[0002] The composition of volatile organic waste gas from chemical enterprises is relatively complex, generally a multi-component mixed gas, usually flammable, explosive and toxic. At present, the most commonly used volatile organic waste gas treatment facility in chemical enterprises is the regenerative thermal incinerator (RTO), whose working principle is: after the organic waste gas absorbs heat and heats up in the regenerative chamber, it enters the combustion chamber for high-temperature incineration (800-1000℃), and the organic matter is oxidized into inorganic components such as CO2 and H2O, and then passes through another regenerative chamber to store heat and then discharge at low temperature. The stored heat is used to preheat the newly entered organic waste gas, and the airflow direction is periodically changed to maintain the stability of the furnace temperature.

[0003] In the process of oxidizing organic waste gas, the existing organic waste gas regenerative thermal incinerator generates dust which is adsorbed on the inner wall of the pore structure on the ceramic regenerative body, and the thickness of the dust layer gradually increases, making it difficult to clean and collect, thereby reducing the preheating effect of the ceramic regenerative body on the incoming organic waste gas. Therefore, in view of the above problems, an organic waste gas regenerative thermal incinerator is proposed. Utility Model Content
