[0020] See also Figures 1 to 3The utility model discloses an active carbon adsorption steam desorption organic waste gas treatment device, including vertical jar 1, the outer wall of vertical jar 1 is integrally formed with the lateral jar 2 of outward protruding, vertical jar 1 and lateral jar 2 are mutually perpendicular state distribution, the bottom of vertical jar 1 is installed with the air intake mechanism extending to the top of vertical jar 1, the top of vertical jar 1 is installed with the desorption mechanism extending to the below of vertical jar 1, the inside of lateral jar 2 is installed with active carbon frame 11, and active carbon frame 11 is vortex structure, and the inside of active carbon frame 11 is filled with active carbon in continuous annular cavity.

[0021] In the embodiment: first in the adsorption waste gas contained in the particle and organic matter through the lower half of air intake mechanism enter to vertical jar 1 and lateral jar 2, and after entering and being fully contacted with the active carbon in active carbon frame 11, the component contained in waste gas can be intercepted, filtered at this time is intercepted by active carbon, because active carbon frame 11 is vortex structure, therefore after waste gas enters active carbon frame 11, along its vortex track flow, fully contact with active carbon, thereby realize more effective filtering efficiency, after waste gas flows to the central position of active carbon frame 11, can be discharged through the upper half of air intake mechanism;

[0022] During the long time use of active carbon, active carbon needs to be desorbed, so as to maintain the filtering performance of active carbon, at this time, the components attached to the inside of active carbon are washed out by desorption mechanism.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 , the air intake mechanism is located below the air inlet pipe 4 of vertical jar 1, the output end of air inlet pipe 4 is connected with the input end of lower connecting pipe 13 through a tee pipe, the output end of lower connecting pipe 13 is connected with the bottom end of vertical jar 1, the inner cavity of lower connecting pipe 13 is connected with the inner cavities of vertical jar 1 and lateral jar 2, the air intake mechanism further includes an upper connecting pipe 5 installed on the top end of vertical jar 1 and extending into the inner cavity of lateral jar 2, the upper connecting pipe 5 penetrates the active carbon frame 11 at the end of the inner cavity of lateral jar 2 and extends to the central position of active carbon frame 11.

[0024] In the embodiment: when filtering waste gas, the air pump inputs waste gas into lower connecting pipe 13 through air inlet pipe 4, and the waste gas enters vertical jar 1 and lateral jar 2 through lower connecting pipe 13, at this time, the air pressure in vertical jar 1 and lateral jar 2 increases, and because the air pressure always flows from high pressure to low pressure, the waste gas enters active carbon frame 11 and fully contacts with the active carbon in active carbon frame 11, thereby realizing the filtration of waste gas, and then the waste gas flows to the most central position of active carbon frame 11 and is discharged from the upper connecting pipe 5.

[0026] In this embodiment: when desorbing the activated carbon plate, the steam pump is first started to transport the steam to the desorption tube 6 through the steam pipe portion 8, and then the high-temperature steam enters the center of the activated carbon frame 11 through the upper connecting pipe 5. The high-temperature steam circulates along the vortex route to achieve desorption of the filtered components and the activated carbon at high temperature. Then the steam enters the exhaust pipe 3 through the lower connecting pipe 13, and enters the corresponding closed collection container through the exhaust pipe 3. Finally, the high-pressure air pump is started to input dry air into the gas pipe portion 9. The dry high-pressure air enters the upper connecting pipe 5 through the desorption tube 6, and then enters the center of the activated carbon frame 11 through the upper connecting pipe 5.

[0030] In this embodiment, the conical surface structure design of the guide surface 12 can achieve smooth discharge of steam and dry high-pressure air, thereby reducing discharge resistance.
