The organic waste gas to be treated enters the ceramic medium layer of regenerator 1 (the ceramic medium "stores" the heat of the previous cycle). The ceramic releases heat and the temperature decreases, while the organic waste gas absorbs heat and the temperature increases. After leaving the regenerator, the waste gas enters the oxidation chamber at a higher temperature. At this time, the temperature of the waste gas depends on the volume of the ceramic body, the flow rate of the waste gas and the geometric structure of the ceramic body .      In the oxidation chamber, the organic waste gas is heated by the burner to the set oxidation temperature of 760 ℃, so that the VOC component is decomposed into carbon dioxide and water. Since the exhaust gas has been preheated in the regenerator, the fuel consumption is greatly reduced. The oxidation chamber has two functions: one is to ensure that the exhaust gas can reach the set oxidation temperature, the other is to ensure that there is enough residence time to fully oxidize VOC in the exhaust gas. The waste gas is incinerated in the oxidation chamber to become purified high-temperature gas, and then leaves the oxidation chamber and enters the regenerator 2 (which has been cooled in the previous cycle). After heat release and cooling, the waste gas is discharged, while the regenerator 2 absorbs a lot of heat and then heats up (for heating the waste gas in the next cycle). The purified waste gas is discharged into the atmosphere through the chimney, and a small stream of purified gas is introduced to clean the regenerator 3. The exhaust temperature is about 40 ℃ higher than the intake temperature. After the cycle is completed, the inlet and outlet valves are switched once, and then enter the next cycle. The exhaust gas enters from the heat storage chamber 2 and the heat storage chamber 3 is discharged. At the same time, a part of purified gas is introduced to clean the heat storage chamber 1. Work continuously and again.
