Abstract

Provided is a grading air distribution type heat accumulating type incinerator which comprises a purging auxiliary fan, a main fan, a regenerative chamber, an oxidation chambers, an efficient waste heat boiler, energy-saving type pilot flame and a chimney. The regenerative chamber is internally provided with an air distribution section, a heat storage section, an air ring pipe, energy-saving pilotflame and a secondary air ring pipe. By adopting a combustion process of first performing preheating and then performing gradation air distribution incineration, medium and low concentration organicwaste gas containing oxygen (or containing a small amount of oxygen) can be treated. The waste gas cannot maintain the combustion. When the waste gas is treated by a conventional heat accumulating type incinerator, the waste gas needs to be diluted with plenty of air to below the deflagration limit of 25%, so that the waste gas treatment amount, equipment investment and application difficulty aregreatly increased. The grading air distribution type heat accumulating type incinerator is an innovation based on the conventional heat accumulating type incinerator, this type of organic waste can befully and efficiently treated, and the goals of cost reduction, high efficiency, economy and environmental protection are achieved.

Description

technical field [0001] The present invention relates to a device for treating waste gas, in particular to a device for treating waste gas containing high concentrations of volatile organic compounds (VOC), in particular to a graded air distribution type regenerative incinerator . Background technique [0002] With the wide application of organic chemical products in industrial production, more and more volatile organic pollutants enter the atmosphere, and the discharge of these pollutants seriously endangers people's health. At present, the removal methods or processes of VOCs mainly include adsorption, absorption, condensation, membrane separation, biodegradation, low temperature plasma, photocatalytic oxidation and combustion. Among them, the method of using regenerative incinerator (RTO) to treat industrial organic waste gas has been widely used due to its advantages of high purification rate, high thermal efficiency, simple maintenance, and self-heating operation under ...
