[0002] Waste gas treatment refers to the purification and treatment of waste gas to reduce its impact on the environment and human health. Industrial production usually produces a large amount of waste gas, and the waste gas needs to be treated accordingly and meet the emission standards before it can be discharged into the atmosphere. Therefore, a corresponding waste gas treatment system is required.

[0003] The box body is usually a double-layer structure with an upper adsorption net. Exhaust gas is adsorbed by adsorption bricks placed on the adsorption net. However, the adsorption bricks in the box are also consumables. After long-term use, the adsorption capacity decreases and needs to be replaced. At the same time, since the upper adsorption net is fixedly connected to the inner wall of the box, the upper adsorption net cannot be disassembled, which makes it inconvenient to inspect and replace the adsorption bricks. At the same time, the side sealing plates and oblique sealing plates of the box body are both single-layer structures, and the thermal insulation effect is poor. Utility Model Content

At the same time, interlayers are provided inside the two oblique sealing plates and the side sealing plates, and thermal insulation cotton is provided in the interlayer, which is conducive to the insulation of the box during desorption. In the prior art, since the adsorption bricks in the box are also consumable The material has a decreased adsorption capacity after long-term use and needs to be replaced. At the same time, since the upper adsorption net is fixedly connected to the inner wall of the box, the upper adsorption net cannot be disassembled, which is not convenient for maintenance and replacement of adsorption bricks. At the same time, the side sealing plates and oblique sealing plates of the box are both single-layer structures, and the thermal insulation effect is not good. This processing system is convenient for disassembly and assembly of the upper adsorption net, and replacement of adsorption bricks placed on the upper adsorption net, which is convenient for maintenance personnel to inspect the entire interior of the box.

The outer wall of the square tube 4 is fixedly connected to the support frame 6, and the top of the two support frames 6 in the same group is installed with an upper adsorption net 7. The inside of the side sealing plate 1 and the two inclined sealing plates 2 is provided with an interlayer 8, and the inside of the interlayer 8 is provided with thermal insulation cotton 9. The thermal insulation cotton 9 is beneficial to the insulation of the box during desorption. When replacing the adsorption bricks, open the inspection door 16, take out the adsorption bricks on the upper adsorption net 7 and the lower adsorption net 3, and then put the adsorption bricks in respectively. When inspecting the internal situation, it is only necessary to take out all the upper adsorption nets 7 and the adsorption bricks, and then inspect the inside of the box.

[0028] The upper adsorption net 7 and the lower adsorption net 3 are both made of activated carbon materials. The activated carbon can remove odors and adsorb smaller impurities at the same time. The top of the upper oblique sealing plate 2 is connected to an adsorption air inlet valve 10 through a plurality of bolts, the bottom of the lower oblique sealing plate 2 is connected to an adsorption air outlet valve 11 through a plurality of bolts, the outer wall of the upper oblique sealing plate 2 is connected to a desorption air inlet valve 12 through a plurality of bolts, and the outer wall of the lower oblique sealing plate 2 is connected to a desorption air outlet valve 13 through a plurality of bolts.

[0029] A temperature sensor 14 of model "602F-3500F" is installed on the inner wall of the rear side of the side sealing plate 1, and there are two temperature sensors 14. A nitrogen inlet 15 is fixedly connected to the outer wall of the upper oblique sealing plate 2, and there are two nitrogen inlets 15. When the temperature sensor 14 detects that the temperature is too high, an external device injects nitrogen into the box to cool down the inside of the box.

[0030] An inspection door 16 is installed on the front of the side sealing plate 1, and a plurality of supporting feet 17 are fixedly connected to the outer wall edge of the lower oblique sealing plate 2, and a plurality of supporting feet 17 are fixedly connected to the outer wall of the upper oblique sealing plate 2.

[0031] Working principle: When working in the adsorption mode, the adsorption air inlet valve 10 and the adsorption air outlet valve 11 are opened, the desorption air inlet valve 12 and the desorption air outlet valve 13 are closed, the airflow enters the box through the adsorption air inlet valve 10, and then passes through the adsorption bricks. The adsorption bricks adsorb the harmful substances in the exhaust gas, and finally the airflow flows out of the box through the adsorption air outlet valve 11. When the adsorption bricks are saturated with adsorption, desorption can be performed. When working in the desorption mode, the adsorption air inlet valve 10 and the adsorption air outlet valve 11 are closed, the desorption air inlet valve 12 and the desorption air outlet valve 13 are opened, and the high-temperature airflow enters the box through the desorption air inlet valve 12. The airflow passes through the adsorption bricks, and the adsorbed substances in the adsorption bricks are adsorbed. The exhaust gas is desorbed at high temperature, and the desorbed exhaust gas flows out of the box with the high-temperature air flow through the desorption air outlet valve 13, and finally the air flow enters the external catalytic combustion equipment for heating and combustion. When the desorption temperature is too high, the temperature sensor 14 detects it, and the external equipment injects nitrogen into the box through two nitrogen inlets 15 to cool the inside of the box. When replacing the adsorption bricks, open the inspection door 16, take out the adsorption bricks on the upper adsorption net 7 and the lower adsorption net 3, and then put the adsorption bricks in respectively. When inspecting the internal situation, you only need to take out all the upper adsorption nets 7 and adsorption bricks, and then inspect the inside of the box.
