8. The vacuum desorption method of the organic waste gas adsorbent according to claim 1, characterized in that: the diameter of the middle cavity of the catalytic box (19) is larger than the caliber of the upper port of the catalytic box (19).
9. The vacuum desorption method of the organic waste gas adsorbent according to claim 1, characterized in that: the method comprises the following steps:
s1: firstly, materials are injected into the inner cavity of the desorption tank (22) from the material injection pipe (11), and then the heating outer tank (1) is heated by the two heating plates (2), so that the inner cavity of the desorption tank (22) is heated by the heat conduction pipe (24) on the side wall of the desorption tank (22), the heating efficiency is higher, and the effect is better;
s2: the vacuum pump (6) works to blow the waste gas in the desorption tank (22) into the drive box (10) through the blowing pipe (5) through the suction pipe (9), the blowing impeller (25) in the drive box (10) rotates at a high speed, so that the stirring rod (4) is driven to fully stir the materials in the inner cavity of the desorption tank (22), the desorption effect and efficiency are improved, the motor drive is not needed, the energy is saved, the environment is protected, the desorption tank (22) is in the initial reaction stage, the valve (7) on the suction pipe (9) is closed, the valve (7) on the auxiliary suction pipe (8) is opened, the vacuum pump (6) can be ensured to work to drive the blowing impeller (25) in the drive box (10) to rotate, and the stirring effect is achieved;
s3: then, the gas discharged from the driving box (10) can be conveyed to a reverse condenser (14) through an air conveying communicating pipe (13) for liquefaction treatment, and is discharged into a reverse heat exchanger (21) for gas evaporation after being filtered by a filter box (15);
s4: hot steam exhausted from the heat exchanger (21) is introduced into the catalytic box (19) and is put into catalyst fillers on the two filter screen plates (28) to carry out contact reaction to purify gas, and then the gas backflow is carried out to-and-fro operation on the heat exchanger (21) to be more sufficient;
s5: when needing to discharge the change to the catalytic material in catalysis case (19), cylinder (17) work drives pull rod (27) and descends, thereby it falls down to drive two filter plate (28) and falls the middle part of catalyst case (19) and reach the discharge, when throwing the material then cylinder (17) drive two filter plate (28) and progressively stretch out catalysis case (19) upper end oral area, then operating personnel carry out progressively put in the catalyst can, convenient and fast, avoid the inconvenient problem of catalyst input in the catalysis case (19) among the prior art.
