Exhaust gas combustion furnace and exhaust gas treatment equipment

Abstract

The invention discloses an exhaust gas combustion furnace and exhaust gas treatment equipment. The exhaust gas combustion furnace comprises a combustion chamber, heat accumulators, gas preheating pipelines, combustors, an exhaust gas conveying pipeline, an exhaust pipeline and a gas conveying pipeline, wherein the combustion chamber comprises a first combustion chamber and a second combustion chamber; the upper part of the first combustion chamber communicates with the upper part of the second combustion chamber; each heat accumulator is positioned at the bottom of the combustion chamber; a gas inlet of each gas preheating pipeline is used for communicating with the external gas conveying pipeline; each heat accumulator is internally provided with the corresponding gas preheating pipeline;a gas outlet of each gas preheating pipeline extends out of the combustion chamber; and the air outlet of each gas preheating pipeline is provided with the corresponding combustor. By the scheme, onone hand, the exhaust gas combustion furnace increases the utilization rate of gas, on the other hand, the exhaust gas combustion furnace quickens decomposition of harmful gases in the exhaust gas, reduces consumption of the gas, improves the incineration efficiency and effect of the exhaust gas and achieves good economical benefits and environmental protection benefits.

Description

technical field [0001] The invention belongs to the field of waste gas combustion, and in particular relates to a waste gas combustion furnace and waste gas treatment equipment. Background technique [0002] VOCs (Volatile Organic Compounds) are volatile organic compounds. There are many methods to deal with volatile organic compounds. Among them, catalytic combustion (catalytic oxidizers) is an effective method for treating waste gas containing organic solvents. [0003] The device for treating organic waste gas has a regenerative catalytic combustion device, which has high utilization efficiency of catalytic combustion waste heat. It is an internationally recognized energy-saving organic waste gas treatment device, but because the catalyst used is generally a noble metal catalyst, the cost of the catalyst is relatively high. , and the current life of noble metal catalysts is not long enough, therefore, the recycling of catalysts has also become an important factor limiting...

AI Technical Summary

Problems solved by technology

[0004] The existing regenerative combustion device preheats the industrial waste gas first, which can improve the treatment effect of industrial waste gas under certain circumstances, but the gas and industrial waste gas in the existing regenerative combustion device cannot be fully combusted, which on the one hand reduces the The utilization rate of gas, on the other hand, also slows down the decomposition of harmful gases in industrial waste gas
