PLANT WITH AT LEAST ONE ADSORPTION CHAMBER FOR THE ADSORPTION OF CARBON DIOXIDE FROM THE STOCKROOM AIR OF A STOCKROOM

The invention concerns a plant with at least one adsorption chamber for the adsorption of carbon dioxide from the stockroom air of a stockroom for fruits, vegetable, flowers, mushrooms u.dgl, with the help of a firm adsorbent, in particular activated charcoal as well as for the regeneration of the adsorbent with the help of a gaseous desorption means, in particular air. Hiehei is to make the plant possible in accordance with the invention both such procedures, with which the products mentioned in a cooled stockroom up to their distribution are stored, and the procedure, with that ungerei£te fruits od.dgI, in a stockroom under supply by warmth to be after-matured. Can be likewise necessary, ungereifte fruits od.dgI to store first in a cooled stockroom during a certain period and to then submit the stored material in the same stockroom shortly before its distribution to the consumers by supply of warmth a Nachreffungsprozeß. With all procedures it is necessary to reduce the Kohlendioxydgehak of stockroom air to a certain percentage whereby with a Nachreifungsprozeß a substantially stronger sinking of the carbon dioxide content is necessary. For example it is with a pure storage of fruits u.dgl. admits to make possible with the help of a suitable controlled and/or regular atmosphere as well as with a carbon dioxide content of stockroom air favorable for the stored material a durability of fruits stored in gekühIten stockrooms u.dgl. during one period of several months. Bekanndich remain for example such as apples u.dgl, their vital functions to fruits also after the harvest, as oxygen is used and carbon dioxide is produced. The faster these “breathing procedures” run, with which sugars and other nutrients are used, all the faster age the fruits. A slowing down of these breathing procedures lets itself reach by it that the Sanerstoffgehalt of the camp atmosphere is substantially lowered in relation to the oxygen content of normal air, with the storage of fruits appropriately on approximately 3 VOL. - %. Such an atmosphere regarding Sauerstoffund carbon dioxide content, deviating from the normal air composition, can be manufactured in a well-known procedure thereby that in a cooled and outward to a large extent gas-tight locked stockroom from there delivered carbon dioxide is removed for untergehrachten fruits under oxygen admission from the stockroom atmosphere, up to a desired percentage. That is more and more used up by the respiration of the stored material oxygen content of the bearing play. As soon as the desired minimum value of approximately 3 VOL. - %, can this value in the consequence is reached by supply of outside air be maintained. It is however more favorable to reduce the oxygen content of the bearing play artificially to the desired value. As firm adsorbent activated charcoal or Zeollthe can be used favourably. Under firm adsorbents so! however also if such len to be understood, with those a granulated solid, e.g. gravel in the sense of the invention, which carriers for a liquid adsorbent, like e.g. a Pottaschelösurtg, forms. It is with adsorption devices for the reduction of firm, regeneratable adsorbents well-known, as soon as the firm AdsorptionsmitteI is satisfied with carbon dioxide e.g., like activated charcoal, the absorbent, to preferably regenerate by desorption gas, fresh air from the atmosphere, again. So far it was usually, or turned around the reversal of stockroom air to fresh air by in Zuführungsbzw. Abf'ührungsleitungen arranged valves by means of electrical, hydraulic or pneumatic Äntriebsvorrichtungen to make, i.e. for the manipulation of these control valves are necessary additional drive systems. A safe mode of operation of an adsorption device essentially depends on the switching reliability and the tightness of these valves. In addition relative to large torques are necessary the change-over of such valves. The well-known systems are thus in more constructional look extremely complex. The invention set itself a plant with at least one adsorption chamber for the adsorption of carbon dioxide from the stockroom air of a stockroom for fruits u.dgI, to the goal, with which a more economical mode of operation becomes possible and is substantially simpler in particular in its constructional training regarding the controls. This task is solved with a plant of the kind initially specified according to invention thereby that to those or one adsorption chamber each a piece of link is attached, in which for the promotion of stockroom air and/or desorption means a blower with switchable promotion direction is arranged, and that the kind the adsorption chamber branches out the attached piece of link to two lines on that the adsorption chamber cleared away side of the Gehläses, and that further two lines directly or over eizweites piece of link are attached to the adsorption chamber, whereby in the line for the supply of stockroom air into the adsorption chamber and in the line for the guidance of the Lagerraumlu£t from the adsorption chamber into the stockroom as well as in the line door the supply of desorption means into the adsorption chamber and in the line for the Wegfiihrung of the desorption means from the adsorption chamber as a function of the promotion direction of the blower on the pressure of stockroom air and/or of the pressure the desorption means steered check valves in each case is arranged, how those! 5 check valves in accordance with their passage direction are so arranged that either only stockroom air can flow or only desorption means by the adsorption chamber. As Rückschlagldappen automatic, commercial check valves with the plant according to invention, which e.g. from a plastic, how exist polyvinyl chloride (PVC, can), to be used. At the respective operational sequence of a Adsorptionsoder of a regeneration interval the promotion direction of the blower, e.g. by phase change-over, can be changed. Favourably the plant according to invention can be equipped with two parallel switched adsorption chambers, in which alternately an adsorption and/or a regeneration of the adsorbent can be accomplished in each case at the same time, whereby each chamber a blower switchable in the promotion direction is assigned in each case and the two chambers during one time interval alternately in the Adsorpfionsbzw. Desorption enterprise by attitude of the two blowers in opposite promotion direction to be driven know. Further characteristics of the invention result on the basis of and in the following described remark examples of the invention represented in the designs. In the designs shows: Fig.1 a plant with an adsorption chamber and a Fig.2 a plant with two parallel switched adsorption chambers, in which alternately an adsorption and/or a recovery of the adsorbent is accomplished in each case at the same time. An adsorption chamber --1-- in accordance with Fig.1 a filling from granulated activated charcoal contains. To the lower part of the chamber --1-- is a Zwlschenleitnngsstück --2-- attached, into a blower switchable in the promotion direction --3-- is arranged for the circulation of stockroom air from a stockroom --4-- by the adsorption chamber and of this into the stockroom and/or for the promotion of fresh air by the adsorption chamber. During one adsorption period stockroom air becomes from the stockroom ---4-- by a line --5-- with due to the blower propelled against the clockwise direction --3--, e.g. a Ringoder turning piston blower, opened check valves --6 and 8-- by the adsorption chamber --1-- promoted, whereby carbon dioxide is adsorbed. From the chamber --1-- stockroom air flows by a line --7-- with the opened check valve --8--, again into the stockroom --4-- back. During an adsorption interval are in the lines --9 and 10--, which serve during a regeneration interval for the promotion of the desorption means, arranged check valves --11 and 12-- closed. During a following rain radon interval the blower becomes --3-- in its promotion direction switched (see not full-taken off arrow). Thus it is caused that the check valves --6 and 8-- close and the check valves --11 and 12-- open. The DesorptionsmitteI, in the remark example fresh air, becomes then from the blower --3-- by the line ---9-- and a Zwlschenleitungsstück --13-- by the adsorption chamber --1-- sucked, hiebei from the adsorbent adsorbed Koh takes up] endioxyd and becomes by line --10-- into the external atmosphere exhausted. The length of time Adsorptionsund of regeneration intervals is Rir each special AnwendungsfaU differently. The change-over of the blower can be caused for example with the help of a time switch or be stopped if necessary also by Hafid. Fig.2 finally shows a device with two parallel switched chambers, whatever can be arranged as a construction unit, naturally spatially separately. Since the device differs opposite Fig.1 only thereby that two parallel switched adsorption chambers are arranged, the individual design features are in Fig.2 with the same reference numbers as once in Fig.1, however with an apostrophe and once with two apostrophes additionally provide. The promotion direction of the blower --3 '-- and the direction of flow of the bearing play during the adsorption interval is äses by full-taken off arrows and the direction of rotation of the Geb] --3 "-- and the direction of flow of the fresh air is during the regeneration interval through not full-taken off Pfei! e marks. The plant represented in Fig.2 represents an operating condition, with which in the right chamber --1 '-- an adsorption takes place, during in the left chamber --1 "-- the Adsorptlonsmittel loaded with carbon dioxide is regenerated. Hiezu turns in the piece of link --2 '-- arranged blowers --3 '-- against the clockwise direction, so that in the line --5 '-- and in the line --7 '-- arranged check valves --6 ' and 8 '-- opened, there they are as a function of the promotion direction of the blower --3 '-- of the pressure of stockroom air in the stockroom --4-- are subjected. Thus stockroom air becomes from the stockroom ---4--- by a line --14--, the line --5 '-- and the piece of link --2 '-- by the chamber --1 '-- promoted and herein from air carbon dioxide adsorbs. -- 4 - NR 3 /40 stockroom air, from carbon dioxide was washed, becomes then by line --7 '--and a connecting cable --15-- into the stockroom ---4--- led back. The Riickschlagklappen --11 ' and 12 '-- are closed by the dead weight of their valve disks. During the time interval, in chamber --1 '-- Carbon dioxide from stockroom air is adsorbed, becomes that the chamber --1 "-- assigned blowers --3 "-- in the Zwischenleitnngsstüek --2 "-- in to the Förderrichtnng of the blower --3 '-- opposite direction, i.e. in the clockwise direction, in enterprise set. Hiedurch is caused that in line --9 ", 10 "-- arranged Riickschlagklappen --11 " and 12 "-- open, while in line --5 " and 7 "-- arranged Rückschlagldappen --6 " and 8 "-- are closed. Thus serving fresh air becomes by the lines as desorption means --9 "-- and the piece of link --13 "-- of the blower --3 "-- by the chamber --1 "-- sucked, herein taken up carbon dioxide carries forward and flows by the line from the adsorbent ---10 "--- into the external atmosphere off. It is still pointed out that the Zwischenleitungsstticke --13-- (Fig.1) --13 ' and 13 "-- (Fig.2) to be omitted, and the lines can --7, 9; 7 ', 9 ' and 7 ", 9 "-- separately directly to the chambers --1, 1 ', 1 "-- to be attached can.
