The body of liquid is subjected to ultrasonic vibrations to impart loosening forces to the solids deposited on the screen, thereby dislodging them and suspending them in the zone. This causes the solids, which are still under the influence of the ultrasonic vibrations, to settle and concentrate in the liquid at the bottom of the zone. The screen is then moved, and the solids removed from aqueous suspension and in their concentrated solid state from the bottom of the zone. The bath has relatively small volume, so that after solids are deposited on the screen within the tank and are subsequently concentrated on the bottom ...

Method for cleaning a filter device, and filter device for applying the method

The invention relates to a method for cleaning a filter device for liquids, in particular swimming pool water, in which the liquid to be filtered is drawn off from a container via filter elements having an alluvial filter aid layer and which involves, in the cleaning operation, the filter aid layer being washed off into a transverse channel which has a discharge orifice and is disposed at the lowest point of the container. So as to be able to reliably dispose of the contaminated filter aids it is proposed that, during the cleaning operation, the container first be emptied via the filter elements, applying filtration, apart from a residual amount of liquid and that the filter aid washed off be mechanically discharged from the transverse channel and be delivered to a receptacle.

Self Cleaning Debris Screen for Runoff Water Separation Apparatus

A runoff water vault may be divided into an input chamber which receives runoff water and a second chamber which also separates and stores buoyant and non-buoyant materials separated from the runoff water stream. While the separators in such systems remove particles of different densities than water quite well, they have difficulty in removing neutrally buoyant debris. Screens are added into the water flow stream to catch and remove particles of neutral buoyancy. The screens are mounted in a manner which permits lateral movement of the screen relative to the water flow, such as shaking and/or flexing. Screen movement imparts pressure differential across the screen perforations releasing debris trapped against the screen, so that the debris will fall into an entrainment area and allow increased flow through the screen. The screens may also include one or more turbulator fins for intersecting the water flow and transferring energy to the screen, imparting lateral movement to the screen.

Catalytic solid-liquid multiphase reactor

FIELD: chemical engineering. SUBSTANCE: reactor is designed for continuous multiphase catalytic reaction, for instance, for production of higher hydrocarbon fuels. Gas reagents are introduced through gasproof plate into suspension, which contains product and finely disintegrated catalyst. Liquid product is separated from the rest of suspension using filter cell enclosing filter element. Over the latter, a pressure drop is produced by the aid of constant-level device inside filter cell, which maintains level of filtrate inside filter cell below suspension level. Suspension is maintained in the continuous- stirring state owing to introducing gaseous components, e.g. steam bubbles. Fluctuations of pressure drop through filter element prevent the latter from clogging. Gas spaces above the filtrate and suspension communicate with one another. EFFECT: facilitated separation of catalyst particles during reaction. 21 cl, 7 dwg, 2 ex ОсСзЗО0сСЬс ПЧ Го РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (19) ВИ "” 2 120 820 ^^ Сл 51) МПК в 04 8/22, С 07 С 1104, В 01 3 8/26 12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 94040725/25, 24.02.1993 (30) Приоритет: 25.02.1992 СВ 9203958.5 (46) Дата публикации: 27.10.1998 (56) Ссылки: ЗЧ, авторское свидетельство, 1428179, кл.В 01 4 8/22, 1988.

Filamentary filter elements for contaminated fluids - arranged as concentric cylinders between upper and lower grids in housing

The filter consists of lengths of metal, plastic or natural filaments forming vertical concentric cylindrical layers whose ends are held between the rings of transverse upper and lower grids in a lidded housing, these layers forming a filter insert for the impure medium. A central vibratory rod aids periodic regeneration of the filter, loosening adhered material which would normally drop vertically into an exit hopper. The filaments may be homogeneous or vary in compsn. size or shape depending on the material filtered, and for abrasive material filtered and for abrasive materials may be chain with metal or synthetic links. Filaments may be non-reactive or coated with catalytic or other material reacting with the filtered media. The filters clean gases or liqs. in a wide range of heavy and light industry, e.g. mining, cement prodn., foodstuffs, fuel, lubricants. Regeneration is easier and less frequent than for known types, e.g. with multiple fabric bags.

Method and means for filtering the solvent used in chemical cleaning machines

993,184. Filters; filtering systems. M. BOHLER, and F. WEBER, [trading as BOHLER & WEBER KOMM.-GES.]. Oct. 22, 1962 [Oct. 27, 1961], No. 39940/62. Heading B1D. In a process for filtering solvent in chemical cleaning machines, filter powder is added from pin trap 2, Fig. 2, to solvent from cleaning drum 1, in a single quantity sufficient for filtering several charges of solvent to filter casing 6. The filter powder is floated afresh on to filter elements in 6 at the start of each charge, and the accumulated cake is removed therefrom, by means operable from outside the casing, at the end of each charging operation without removal from the filter casing. Solvent, moved by pump 4, may be recycled to the filter casing via pipes 7 and 8. A preferred filter apparatus comprises a casing having conical bottom 12, Fig. 1, and a plate 13 with filter elements 15 connected thereto under tension. A domed cover 14 forms hollow space 20 for filtered solvent, discharging through pipe 21. Solvent enters pipe 16, which has one outlet 18 at the end of riser pipe 17, and another outlet 19 directed downwardly in such a manner that the solvent may impinge against the conical base of the casing. Preferably, outlet 19 is is placed off-centre and skew of the longitudinal axis of the casing. Sedimented filter powder is thus swirled upwardly, and light particles, e.g. fluff, are swirled downwardly, so that an even deposit on the filter elements is obtained. Outlets 18 and 19 may be provided with nozzles to subdivide the flow. Filter elements 15 are coiled springs. Filter cake is removed from the elements by means of pusher rods 22, extending inside the elements. When the rods 22 connected by yoke 23 are pushed downwards by actuator 25, the apertures between the coils of the springs are enlarged, causing the cake to fall away to the bottom of the casing. Alternatively, compressed air or back-flushing may be used to remove the cake. Sludge is removed, e.g. at the end of each day's ...
