Through the above manner, on the one hand, the timely discharge of the invalid adsorbent particles is achieved in the adsorption process, the difficulty of increasing the passing of waste gas is avoided, on the other hand, after the adsorption is completed, the adsorbent particles at the bottommost layer are convenient to replace, when the blocking screen 4 moves to the final position, the blocking screen is lowered to the position below the material taking hole 1b, and most importantly, the upper adsorbent particles do not pass through the material discharging hole 3a to slide downwards in the removal process due to the blocking effect of the rotary scraper 3 on the adsorbent particles, so that the replacement of the adsorbent particles at the bottommost layer is convenient to realize. The top of the reaction tank body 1 is provided with a feed inlet, and after part of adsorbent particles are discharged, new materials can be fed into the reaction tank along the feed inlet again.

If the air outlet pipe 7 is of a vertical pipe structure, the exhaust gas emission area is limited, and the main reason is that the adsorbent particles are covered on the top of the air outlet pipe 7, therefore, as shown in fig. 3, the air outlet pipe 7 is of a pipe structure, the air outlet pipe 7 is horizontally arranged, the middle part of the air outlet pipe 7 is communicated with the top of the air guide pipe 5, and a plurality of air holes are formed in the outer edge of the air outlet pipe 7. Through upwards discharging along air duct 5, will be discharged along the bleeder vent on the outlet duct 7, because the part overall structure of bleeder vent on the outlet duct 7 is longer for the region that waste gas was discharged enlarges, and when air duct 5 rotated, can drive outlet duct 7 and carry out synchronous rotation, further improvement outlet duct 7 was discharged regional.
And when outlet duct 7 rotates, the marginal adsorbent granule of outlet duct 7 is in the state of downwardly flowing, and this resistance that just makes the rotatory time-dependent resistance of outlet duct 7 reduce, and outlet duct 7 is rotated in the convenience, and the rotatory time-dependent stirring adsorbent granule of outlet duct 7 for the adsorbent granule can more smoothly be discharged along discharge gate 3a.
As shown in fig. 5, a plurality of fan-shaped frames 3b are arranged at the top of the rotary scraper 3, the bottom of each fan-shaped frame 3b is of an opening structure, one side of the circumference of the fan-shaped frame 3b is of an opening structure, and a cover plate 3c is rotatably covered on the opening of one side of the circumference of the fan-shaped frame 3 b. When the rotary scraper 3 rotates counterclockwise, the adsorbent particles will abut against the cover plate 3c and slide out downward along the opening of the fan-shaped frame body 3b, and enter above the blocking screen 4. On the contrary, when the rotary scraper 3 rotates clockwise, the openings of the fan-shaped frame body 3b are not in direct contact with the adsorbent particles, so that the particles are reduced to pass out of the discharge port 3a, and the particles are further reduced to pass out of the discharge port 3a through the blocking effect of the cover plate 3 c.
The reason why the fan-shaped frame 3b rotates clockwise is that the blocking screen 4 needs to be lifted and reset, and when the blocking screen 4 covers the bottom of the rotary scraper 3, the hollow structure of the fan-shaped frame 3b can store the partially dropped adsorbent particles, and a partial gap is left between the rotary scraper 3 and the blocking screen 4.
As shown in fig. 2, a heating pipe 8 is arranged above the rotary scraping plate 3, and the heating pipe 8 is fixedly connected with the reaction tank 1. And the position that sets up through heating pipeline 8 is close to retort body 1 for when adsorbing, the adsorbent granule that contacts with VOCs first can be heated, along with the discharge of the adsorbent granule after accomplishing the use, can make new adsorbent granule constantly supply to heating area in heating pipeline 8.
And during desorption, the most serious adsorbent particles are also closest to the heating pipeline 8, so that a better desorption effect can be achieved.
As shown in fig. 3, the sliding guide mechanism 6 includes a mounting plate 6b and a plurality of elastic telescopic tubes 6a, the mounting plate 6b is fixedly mounted in the reaction tank 1, the plurality of elastic telescopic tubes 6a are fixedly mounted at the top of the mounting plate 6b, the top of each elastic telescopic tube 6a is fixedly connected with the blocking screen 4, the air duct 5 is rotatably connected with the middle part of the mounting plate 6b, and the air duct 5 is rotatably supported by the mounting plate 6 b. The plurality of elastic bellows 6a apply an upward elastic supporting force to the barrier screen 4 and vertically guide the barrier screen 4 so that the barrier screen 4 can only move vertically when the barrier screen 4 is engaged with the air duct 5.
Because during desorption, the gas is discharged from top to bottom, and the discharged nitrogen can only enter the air duct 5 along the air holes of the air outlet pipe 7 to realize desorption, which leads to longer desorption time, therefore, as shown in fig. 3, 4 and 6, the outer edge of the air duct 5 is provided with an air return hole 5a, the air duct 5 is provided with an elastic sealing mechanism 9 for covering the air return hole 5a, the mounting disc 6b is provided with a cover opening mechanism 10 for opening the elastic sealing mechanism 9, and the fan-shaped frame 3b is provided with a plurality of strip-shaped air holes for allowing VOCs to pass through. When the barrier screen 4 moves downwards to the final position, the cover opening mechanism 10 opens the elastic sealing mechanism 9, so that VOCs downwards pass through the strip-shaped ventilation holes and the air return holes 5a to enter the air guide pipe 5, and finally are conveyed to the combustion chamber along the air guide pipe 5 for post-treatment.
