Description

technical field [0001] The invention relates to the field of organic waste gas treatment, in particular to an RTO combustion system. Background technique [0002] The regenerative thermal incinerator is called "Regenerative Thermal Oxidizer" in English, so it is called "RTO" for short. It oxidizes and decomposes the gas through a high-temperature heating chamber, and then discharges the oxidized and decomposed gas. The existing combustion device heats the organic waste gas to above 760 degrees Celsius through natural gas combustion, resistance heating combustion, microwave heating, etc., so that the VOC in the waste gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through the special ceramic regenerator to heat up the ceramic body to achieve the effect of heat storage. By absorbing a large amount of heat, it is used to preheat the organic waste gas that enters later, thereby saving fuel consumption for heatin...

AI Technical Summary

Problems solved by technology

[0003] The heating device of the existing combustion system usually uses natural gas combustion, resistance heating combustion, and microwave heating. In the process of gas treatment, the natural gas combustion method will produce ammonia and nitrogen, pollute the environment, and the temperature is too high and difficult to control. Low safety factor and other problems; the resistance heating method has high energy consumption, but the heat conversion efficiency is too low, easy to damage and cause short circuit and other problems; although the microwave heating method has high heat conversion efficiency and fast speed, it is harmful to the human body. It is feasible in a closed space, but it is not applicable in the pipeline space, and the heat storage system in the prior art has a relatively simple structure, and only uses ceramic heat storage bodies to store heat for the oxidized gas
