Example two
As shown in fig. 11, in order to more facilitate the replacement of activated carbon and avoid the existence of the swing angle 371 from affecting the vertical placement of activated carbon, in comparative example one, another embodiment of the present invention is as follows: the two sides of the second drawer 32 are provided with sliding grooves 322, and a push plate 39 is connected to one side of the second drawer 32 adjacent to the end plate 36 in a sliding manner; the two ends of the push plate 39 are fixedly connected with sliding blocks which are in sliding fit with the sliding grooves 322; a holding plate 38 is fixedly connected in the middle of the top of the push plate 39; when the device is used, the swing angle 371 exists on the second drawer 32, so that the activated carbon corresponding to one side of the swing angle 371 is difficult to vertically place on the second drawer 32, at the moment, the activated carbon can be placed in the end, adjacent to the end plate 36, of the second drawer 32, and the push plate 39 is driven to move towards the end far away from the end plate 36 by the holding plate 38, so that the activated carbon can be placed in order without being influenced by the swing angle 371.
Working principle: in the prior art, when thermal desorption is adopted to regenerate saturated activated carbon, a steam mixture combined with the hot steam is easily discharged into the atmosphere through an air outlet pipeline to cause pollution, so in order to prevent the situation, when the waste gas generated by a granulator is filtered, the air outlet pipeline is communicated with one end cover 2 and the opposite end cover 2, after the waste gas is sent into a box body 1 through the air inlet pipeline, the porous structure on the activated carbon can be used for absorbing and capturing harmful gas in the waste gas, so that the waste gas fully contacted with the activated carbon is purified, and the purified waste gas is discharged through the air outlet pipeline; meanwhile, a piston rod 44 is arranged in a branch pipe 42 of a steam pipeline 4, when the air pressure in the branch pipe 42 is increased, thrust is generated by the piston rod 44, the piston rod 44 drives a contact plate 43 to move outwards and contact with a baffle 13, so that the baffle 13 separated from the guide module 12 when high-temperature steam is not introduced is extruded to one side of the guide module 12 through the contact plate 43 and is tightly adhered to the guide module 12, and as the bottom of the baffle 13 is also spliced and matched with a rubber strip 15, when the baffle 13 moves and contacts with the guide module 12, sealing of two sides of the box body 1 is realized through the rubber strip 15, so that the high-temperature steam can be prevented from being discharged to the atmosphere through an air outlet pipeline when the thermal desorption regeneration effect of active carbon is realized, atmospheric pollution is caused, meanwhile, the generated steam mixture can be pumped by adopting an air outlet pipe arranged on the other split half box 11, the steam mixture is condensed by being matched with a condenser arranged outside, liquid is prepared, the liquid is treated, and the liquid containing harmful substances is removed by adopting a corresponding treatment mode, and the harmful substances in the waste water is removed relatively lower in cost;
because the service life of the activated carbon is limited, after repeated thermal desorption is carried out repeatedly for a plurality of times, the service life of the activated carbon is reduced, at this time, the activated carbon needs to be replaced, in general, when the activated carbon in the carbon tank 3 is replaced, the first drawer 31, the second drawer 32 or the third drawer 33 can be slipped out, and the activated carbon carried by the activated carbon is enabled to be in an inclined state, at this time, in order to enable the first drawer 31, the second drawer 32 or the third drawer 33 to keep inclined, a support needs to be given, the second drawer 32 or the third drawer 33 of the next layer is usually manually slipped out, and is used for carrying the first drawer 31 or the second drawer 32 above, in the device, when the first drawer 31 is slipped out, the first drawer 32 is used as an example, due to the first connection angle 311 of the bottom surface of the inner end part of the first drawer 31, the second drawer 32 is clamped after a sliding distance, and the swing angle 371 cannot rotate towards the direction close to 36 due to the limitation of the torsion spring, the second drawer 32 can be in the inclined state, the second drawer 32 can be enabled to be in the inclined state, the first drawer 31 is in the inclined state and the first connection angle 311 is enabled to be in the inclined state, and the first drawer 31 is enabled to be in the inclined state and the first connection angle is enabled to be in the inclined state, and the first connection angle is not to be separated from the first connection angle 311 and the first connection angle is used as an end plate 31, and the end plate 31 is required to be in the inclined state, and the first end plate 31 is required to be in the inclined state and the end plate 31 is required to be independently in the opposite a corresponding position to be in the inclined state.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
