and installation worked

The present invention provides, a method of cleaning semiconductor nanoparticles, pollutant residues or contaminants, especially to clean waste gas, liquid and pasty * # as well as setup for carrying. implementing said

- method. , •.. " - "•- '

The invention relates, more particuliereaent ', is a method of windings and " plant for R e i'd U

pollutants, - by employing a biological filter of organic nature, with which the purification is accomplished residues and in '■■■- mm. ' time, the. moving the support had mass filter # to give a final product fuel, made from the filtering medium and pollution once épiirés ". - -,

The. purified. systems heretofore known ion which may be grouped into two types; those that limit * AIs tùër action of a ^ physical separation of constituents which * cytopathy due part to be scrubbed and product, and b) those in which, in addition to forming this separation, there is a biochemical process for transforming the product to be purified.<

Among the systems of the first type agenda such quotas, can include all filtration systems, in which the filter media is unalterable and can, for example, be a porous mass,, such as sand, as well as physical separation systems,, tejls that electrostatic separators..

Among the systems of the second type, there can be mentioned the systems of waste-water treatment, in which exist a fermentation process and a phase separation by decantation, capable combirer in conjunction with a filtration phase *. In the phase dî settling, there remains as residual sludge, whose el the IIR that heat exchanger constitutes to date a large problem ., '••••"

[) years all. case, earlier, whatever the process adopted, was only recoups treating the product to be purified and is consequently obtientw, the solids, liquid and gaseous substances that enter constituting said the pro *

-^V. has

should, which cannot be used in practice, hr the stringency. in some cases the d * wastewater treatment, cms obtains a slurry or liaon # which after being dried, 5 may be used as fertilizer.

The para illeurs # AGEs are the high cost of maintenance and conventional sewage treatment facilities in II was offered that ## is avoided in many cases thereof, after the aêae toto svoir mounted *, with consequent deterioration of the POIs R. AIs place enviléronnant cooked by the déverseaent residues without the toto svoir¹¹ previously subjected th any a purification treatment.

For the purpose of 1 - ^ * Pick ion is to realize a method corresponding station installation CD, which allow the purification of

- pollutant residues; soaking pit using a biological filter, 15 consisting of a bracket or aasse filter of organic nature, which is etched biologiqueasnt and transforcé during opera ' action of filtration of the purifying th residue, the latter being luiaême attacked, and transformed biologiquesent, such that in the assembly, the end of the th *, we get a product with mental 20 EB by the filter medium. ransforaé and the residue pollutant or contaminant cleaned, said end product is favorably usable as a fuel.

In this way, with the method of the invention, is carried out, not only the purification of pollutant residues, but|* 5 also obtains a solid product which may be used and that, th alone, it is to say for its high value ccmbustibi ", in that the installation becomes cost-effective.

Waste contaminants to be purified can be of natutgâteuse #, for example from the industries, 11 - 30 nature quide,>ARs example (urine) originated in stock farms the swine, cattle and other, or blen pasty nature, corm can be the case with the waste sludge wastewater purifying it.

It is another object of the invention is to provide a prey supplied th¹ - a plant for residues PolI -

luants, by which; the liquid products, once purified, ' are eliminated as they are in the form of liquids or as

-; vapor without producing bad smells nor pollution still another object of the invention is to provide a method for purifying a Iin of pollution, in which a fuel gas that we could use.. , '

The above objects and others which will be readily apparent from the following, are reached according to 1' invention by a method comprising passing the residues to be purified, nature gas, liquid or pasty, through a biological filter, the filter medium which is composed of a mass of organic origin at different stages or types of composting. The mass-qnï ^ constitutes the filter medium may consist of vegetable residues, e.g. residues from wood or forest, or still refuse, or mixtures of refuse or waste from wood. This capability provides the method of the invention a large value, by allowing the use and disposal of garbage from urban centers, which constitute auiourd ' poses a large problem. In this case, the method of 1' Pick ion may be applied for single objective, with the removal of the refuse, further enabling an end product and being adapted to have use as a fuel.

Distinct fermentation conditions are initiated in the filtering support by cultures of microorganisms, such as bacteria, fungi and other, previously prepared, so that they are resistant to pollutant residues to be treated *

As can be appreciated, the microorganisms that cause and maintain the fermentation, must be resistant to the medium in which they are to live and must further be capable of producing the decomposition and the purification desdifes residues. Therefore, it is necessary to pre-culturing the ITS micro orcanisms deed, so that takes place their suitability to medium in which there is developing. Once having obtained microorganisms, resistant hr a determined type of polluting residues, it is thereby of the desired base to proceed with the processing and purifying said residue.

11 may occur depending on the ^ time that the strains, in; the method of 1¹ invention for a determined type of residue polluted&Tg degenerate and become unusable for X ' operation on the filter. In this case, it is requires renewal of 1' seed.

The microorganisms used can be susceptible to complete decomposition of the pollutant residues and the mass mistletoe defines a support. F. it thirty them into solid products, be used as fuel "to liquid products harmless * who can be removed at a liquid or gaseous state, and in products * gaseous fuels or non polluting" "•- *

The medium comprises, according to the invention, three consecutive fermentation among which, in the first ' and the third, occur the aerobic fermentation, whereas in the second anaerobic fermentation takes place. ; '

- To maintain substantially constant the boundaries between the three fermentation conditions, as well as activate said fermentation in each state, is set in the presence of oxygen, moisture and temperature in each of said conditions.

In the first and third conditions, is introduced toto âir atmospheric, for providing aerobic fermentation, whereas in the second state, is extracted gasses and liquids, all measures contributing, further, temperatures are maintained.

The first and third fermentation conditions further serve as filters for the gas and liquid that can form in the second stage, by ensuring that their release can occur without bad smell "

The gas that are retrieved directly from the second fermentation step and which are those that can produce malodor, contain large percentages of combustible gasses, so that they can be fed to a chamber for combustion or operation, after having been duly processed "

The mass which constitutes the support filter continuously renewing due passed gradually from the

To maintain the presence of oxygen in the sppcoorLées in first and third conditions of-to-Carmentalion, it may evacuate - gas and the communicating ' directly with the atmosphere.

As is. can understand it, ., . between ' the. similarly tones of the filter media.. which correspond to the three 'conditions, of - fermenting, there is' of PeoPles intermediate transition, in which gradually changed conditions, between the values that correspond to the conditions -' Haltropheâ.'

By extracting the product from the second liquid - state fermentation, in, part in vapor form, together with the hair in gas products in-said-a-tone service, and in part. form-liquid by gravity-or - suction.

Could carry; out the three steps - farmentation together or separately according to, inter alia, environmental conditions, the characteristics of the residue to be cleaned, the nature of the filter media, the cleaning speed desired and the like.

Thus, there can be three statuses fermentation together in a common tank, wherein the first and the-third-in-state of ferment ion to occupy the end zones of said réservoir,-to-a-'tandis -, that the second state occupies the central - portion. thereof.

Onpeufc also implement the three state fermentation in separate tanks. In a first tank, occurs during the first state of aerobic fermentation, from which ' changes' toto riservoir mâsse filter in a second, the takes place the anaerobic fermentation, for passing finally said isasse-in in third tank for the third, state of aerobic fermentation.

According to the invention, the reservoir is supported by brackets could support feet external, which lie around the tank at separate points radially relative thereto. Below the tank is disposed a substructure for supporting the filter media, the tank wall which does not extend to the base defining between them an annular opening, through which a radial worm, which can move angularly along the length of said opening. The seat support is provided with a central opening, which serves as an outlet port, which is located inferiorly connected a pneumatic suction extraction duct.

The worm is supported by its inner end on a pivot bracket, mounted in the central portion of the outlet port of the product. By its outer end, the said worm is connected to an actuation mechanism, for causing rotation thereof and its angular displacement.

Under these conditions, the screw passes through the filtering mass, in the part in which it protrudes beyond the lower edge of the tank by resting on the underlying support. The rotation of the worm results in movement of the filtering mass toward the central port output device, provided in the underbody support, from which said mass is drawn through the discharge line. At the same time, the angular displacement of the worm that runs through the entire substructure supporting, by driving constantly front with a filtering mass which is driven to the central exit opening. In case the worm screw encounters in its angle advance excessive resistance, the driving torque of the actuating mechanism that causes said angle advance is less than a predetermined value, such that when the resistance to said advance is greater than the given value, said mechanism slips, the worm being in this case only the drive rotation so that it does not cease. moving the material toward the orifice âe out¹ ; - * ninarninar.t cu bone. 1 alone * clogging would have been^: occur "by continuing its advance angular"

For^-- prevent in that waterlogging or ' blockages can occur in the central exit opening_F. there is an air inlet duct that extends vertically, inside the tank, in its central part, in. superiorly through the lid and in opening towards a bottom immediately above said central exit opening. In this way, the air drawn in by the discharge line, which extends from the outlet port, - has the effect of penetrating through the central channel mentioned, and further through the opening which receives the worm " by driving constantly the product that the worm moves toward a central exit opening. The supporting feet of the tank remain radially separated from the underbody support, of sufficient magnitude to positioning a circular track, '. on' which is mounted-and may OS moving the mechanism sued the visvis.sans end.

Also manner according to the invention, the reservoir is provided with a series this tabes - vertical, in addition to the aforementioned central conduit, tubes penetrating leedits, equal to the said central duct, the upper lid for closing the reservoir, but reaching only heights corresponding to distinct conditions. A set-their characteristics.. the tubes which extend up to the conditions correspondant'correspondant' with-to-a-aerobic fermentation, serve the input dêdê.l ' SIRs lesdlts conditions.

A part of. ducts qmî. arrive at the area of anaerobic fermentation, can ., is - " prolong.. on. a downwardly inclined path, which opens-a-laterally into the reservoir, and may be used to - the sortie.. des^: liquids " by gravity.

Also, the - ducts. aforesaid perviennent - up to the anaerobic fermentation zone, may be closed at their ends. I imetior -, -;The IQ|" the R;; L-UcoXlecte<3' - liquids, which may be retrieved periodically by suction.

The individual tubes are provided with block valves and radial holes, located at different heights in the region of ferment-ion to which they benzoylacetanilide dir igent *

In the extraction duct is mounted a separation chamber of heavy particles, such as stones, metal objects, pieces of glass and the like. All organic materials which compose the filter media, joined at residue purified, after being passed through the three fermentation steps, density are quite smaller than the particles and objects that may enter said organic materials, whether as particles and objects mineral or organic inclusions which, due to their size, have not been collapse under the effect of the fermentation. The above separator, exploits this density difference for the removal of said particles and objects.

In accordance with 1 * invention, the separator is formed by a chamber below the air extraction duct, in communication with said conduit. In this chamber is a worm, actuated by the corresponding motor, disposed horizontally between two walls of said chamber. O ^ TREs, thence chamber opens laterally into a downwardly inclined conduit, which opens out into the outside bottom it. The mission of the worm is agitate the material that falls from the discharge line and displace it towards the inclined conduit. The open lower end of said inclined conduit is provided with a block valve that can be calibrated. The excess pressure in the discharge line, causes occurs through the inclined conduit, an air inlet toward said extraction duct, variable according to the opening of the valve. This air flow drives again the particles less heavy to the conduit described above. By adjusting the block valve of the lower end of the inclined conduit, can vary the amount of air flowing into the discharge line, so that the drive force of said air is sufficient, the n

tsour send to the pipe-entities for pulling the particles less heavy, corresponding to the organic product, fermented, while the heavier particles fall to the lower end•said tube, from which they are discharged to the outside.

With said system,, may be, simply and reliably, effect the removal of objects and heavy particles or unavoidable, such as soil, stones, crystals, and other metal objects.

The extraction pipe may emerge, beyond the separation chamber, in a hopper portion of which the product is transported, also by 1' through a pneumatic line, crusher in which takes place reducing the size of particles " this operation is facilitated by the absence of foreign bodies, separated by the screen and the separation chamber, and by the conditions under which are the material after fermentation, said material being then readily repulpable.

The output of the mill by a conduit transporting the product to a screen, wherein separate the particles of larger size, then passing to a cyclone, from which it is obtained a powdered product, which # by its characteristics, can be used as fuel injected, and a product of larger particles, which pass in a brr iquetteuse, charged conformation solid compact body, easily manipulâtlesj usable as solid fuels.

Other features and advantages of the invention shall become apparent from the following detailed description of an example of a plant for carrying out the method, illustrative, but none at all limiting, reference to the accompanying drawings, in which ii

figure 1 represents a plan view schematic of one possible form of embodiment of the installation of the invention;

The installation shown in, figures is constituted such that all three conditions of fermentation are implemented in the same tank, although as mentioned above, lesdlts fermentation conditions can be implemented separately, in separate storage containers, and that even the first and at least a portion of or all of said second conditions may be done in the open air, the mass which composes the filter media forming clusters of convenient height, in which. the entry of air into the aerobic fermentation conditions and the output of the MFR of the anaerobic fermentation, can be performed by the aforementioned cluster tubes inserted into appropriate depths. In EE-case, further added in the clusters mentioned, waste contaminants to be purified in the fermentation step the most suitable.

As can be seen in Figure 1, the installation comprises a cylindrical tank 1, vertical-axis, within which consists in carrying out the three steps or fermentation conditions, material-feeding of organic origin which constitutes the filter media is performed by a bucket elevator 2, although it may also be performed by another system of any elevation. The material of organic origin, from a storage area, is poured into a doser 1, from which starts a conveyor belt 4 for powering the crusher 5. Using the metering device 3, by adjusting the amount of material entering the mill 5, so that it does not occur of obstructions in the latter. Said mill 5 is provided to produce a grinding or milling is sufficient to break large objects. For example, in the case where the material of organic origin originates, totally or partially, refuse, this invention finds the mill to cause fragmentation of the refuse bags, boxes, bottles and the like.

From the crusher 5, the product is sent to a screen diu separator 6, are seulsrvant removed the objects of large dimensiao - * - kind of. plastic, metal, crystal and the like. a TES in separate objects come out - 7, while the rest of the product 'is poured onto 1' elevator. 2. said elevator can emerge into - a chamber 8, where ' it passes, by way of the conduit 9, within the reservoir 1.

As shown best in Figure 2, the reservoir 1 comprises a cylindrical wall 10, which is constituted by or covered - internally by a non - of the etchable or deteriorated under the effect-to-'de fermentation, and an upper lid closure. 11, ' while at its lower base, said tank is opened. On the cover 11 there is mounted a soild © receiving '-of the material, such as a cyclone 12, until which reaches the supply line 9. The tank 1 is mounted on brackets. or external supporting legs 13. Below the tank is disposed a basement 14, for example a ' basement concrete or iron, which is slightly separated from the free lower edge of the wall of the tank 10 *. In - the central portion of the floorpan 14 is arranged an outlet 15, from which a line ' extraction pneumatic -■16, . extending radialèsent outside *
