[0038] Multiple heat storage ceramics 21 are uniformly installed inside the gas supply pipe 3, and the multiple heat storage ceramics 21 are arranged at an angle. Burners 22 are fixedly installed on the inner wall surface of the combustion chamber 5, and multiple cooling ceramics 25 are fixedly installed on the inner wall surface of the cooling chamber 6. Multiple through grooves are provided on the surface of the cooling ceramics 25.

The high-temperature purified gas after combustion enters the cooling chamber 6 through the gas pipe 2 and exchanges heat with the internal cooling ceramics 25 to quickly reduce the gas temperature.

[0039] The cleaning mechanism includes a water tank 26, a water supply pipe 27, a water pump 28, and a ring pipe 29. An arc-shaped plate 23 is installed at the lower end of the combustion chamber 5.

The water decomposed inside the combustion chamber 5 flows downward along the drain pipe in the center of the arc plate 23 into the water collection pipe 24. The water flows into the water tank 26 through the water collection pipe 24. When it is necessary to clean the purification tank 1, water pump 28 is started to draw water out of the water tank 26 and deliver it to the inside of the ring pipe 29 through the water supply pipe 27. The water flows out downward through the drain at the lower end of the ring pipe 29. The water flow washes the inside of the purification tank 1. The liquid inside the water tank 26 can be detected and adjusted through the water tank 26.

[0040] Working principle: Organic waste gas enters the centrifuge 13 from the lower part of the purification tank 1 through the inlet pipe 2. The rotary motor 8 starts, driving the main shaft 10 to rotate via the synchronous belt 9. The centrifuge 13 at the lower end of the main shaft 10 rotates at high speed, using centrifugal force to throw large particles of impurities entrained in the waste gas toward the inner wall of the purification tank 1. The scraper 12 on the main shaft 10 rotates synchronously, scraping off the impurities attached to the tank wall. The impurities settle down to the bottom along the funnel-shaped tank wall and are finally discharged through the drain port. The support at the lower end of the centrifuge 13... Plate 14 is fixed to the inner wall of purification tank 1 by support column 15 to ensure stable operation of rotating parts; at the same time, multiple layers of filter screen 18 are installed inside purification tank 1, which further filters the rising pre-treated exhaust gas. The pre-treated exhaust gas enters heat storage chamber 4 through gas pipe 3 and flows through the inclined heat storage ceramic 21 inside. The high temperature heat stored in heat storage ceramic 21 preheats the exhaust gas. The preheated exhaust gas enters combustion chamber 5 through gas pipe and mixes with fuel sprayed from burner 22 on the inner wall, undergoing an oxidation reaction to decompose organic pollutants into harmless carbon dioxide and water. The high temperature purified gas after combustion enters cooling chamber 6 through gas pipe 2, where it exchanges heat with cooling ceramic 25 on the inner wall and quickly cools down to a safe temperature. The cooled purified gas is discharged through discharge pipe 7, completing the exhaust gas purification. The water decomposed inside combustion chamber 5 flows downward along the drain pipe in the center of arc plate 23 into the water collection pipe 24. The water flows into water tank 26 through water collection pipe 24. When it is necessary to clean purification tank 1, water pump 2 8. When started, water is drawn out of water tank 26 and transported to the inside of ring pipe 29 through water pipe 27. The water flows out downward through the drain at the lower end of ring pipe 29, and the water flow washes the inside of purification tank 1. The washing water flows out through the drain outlet. The mounting ring 17 and fixing ring 16 outside the purification tank are fixed by positioning pin 20. The fixing bushing 19 fits against the surface of the main shaft 10. When the filter screen 18 needs to be replaced, the positioning pin 20 is removed and the mounting rings 17 on both sides are pulled out horizontally for replacement.
