According to national requirements, the exhaust gas must be effectively treated, among which chemical adsorption treatment is the most effective.

[0003] The existing chemical adsorption exhaust gas processor, when in use, due to the accumulation of dry solid chemical adsorbent in the reactor, the exhaust gas only contacts and reacts with the outer surface of the chemical adsorbent when it is introduced, the reaction effect is poor and slow, and part of the exhaust gas is not adsorbed in time during the adsorption process and flows out of the reactor, resulting in poor use effect;

The two groups of collecting buckets 15 are respectively arranged at both ends of the lower surface of the filter plate 8. The support plate 16 is used to support the collecting bucket 15 for collecting impurities, so that the collecting bucket 15 can collect the impurities cleaned by the cleaning component 6.

[0025] Both ends of one side of the processing box 1 are rotatably connected to limit knobs 20, and the two groups of limit knobs 20 respectively interfere with one side of the two groups of collecting buckets 15. The two groups of collecting buckets 15 are both arranged above the diverter plate 9. The limit knobs 20 are used to facilitate locking of the collecting buckets 15, thereby ensuring the stability of the collecting buckets 15 in the processing box 1.

[0026] The inner cavity of the treatment box 1 is formed with a filter chamber 17, an adsorption chamber 18 and a reflux chamber 19 from top to bottom in sequence through the filter plate 8, the diverter plate 9 and the breathable partition 10.
