Heat accumulating type catalytic combustion device

Abstract

The invention discloses a heat accumulating type catalytic combustion device which comprises a combustion furnace, wherein a shell is mounted on the outer side of the combustion furnace; an opening and closing valve is arranged on the right side of the combustion furnace; a first burner and a second burner are mounted on the left side and the right side of the lower part of the combustion furnace separately; a smoke flue is arranged between the first burner and the second burner; a first pipe is connected to the lower part of each of the first burner and the second burner; a first valve and a second valve are arranged in the first pipes separately; a second pipe is fixedly mounted at the lower part of the smoke flue; the smoke flue is connected with a reversing valve through the second pipe; the left side and the right side of the reversing valve are fixedly connected with a radiant tube through a first pipeline and a second pipeline; and a combustion body, a heat accumulating body and a mixture body are arranged at each of the tops of the radiant tube from bottom to top. According to the heat accumulating type catalytic combustion device provided by the invention, the combustion bodies loaded with a catalyst are completely combusted at the combustion stage and efficiently transfer heat in a radiation manner, and the advantages of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of catalytic combustion equipment, in particular to a regenerative catalytic combustion device. Background technique [0002] Regenerative high-temperature air combustion technology is a new concept combustion technology that appeared in the late 1980s. Industrial furnaces using this technology can reduce fuel consumption, reduce pollutant emissions, increase production, etc. Regenerative heat exchange technology has been widely used in heating furnaces of metallurgical enterprises such as aluminum furnaces. The traditional regenerative combustion device uses a regenerative flue gas waste heat recovery device, which alternately switches air or gas fuel and flue gas through the regenerator, and the regenerator absorbs the waste heat of the flue gas to heat the air or gas fuel , in order to be able to recover the waste heat of high-temperature flue gas to the greatest extent, and make the temperature distrib...

AI Technical Summary

Problems solved by technology

The traditional regenerative catalytic combustion device does not burn completely, and the heat transfer efficiency is very low, which produces a large amount of pollutants and seriously affects the surrounding environment. Therefore, a new type of regenerative catalytic combustion device is urgently needed in the market
