Exhaust gas incinerator

Abstract

The invention relates to a waste gas treatment device, and in particular relates to a waste gas incinerator which comprises a preheater and an incinerator shell, wherein the preheater is provided with tube nests and a turning wind chamber, wherein a waste gas inlet and a gas outlet are connected to a shell of the preheater, the waste gas inlet is communicated with a waste gas combustion chamber through sequentially passing by a tube pass passage which is formed by the tube nests and turning wind chambers which are arranged in an alternative manner, and a first cavity which is formed between the inner wall of the incinerator shell and the outer wall of the waste gas combustion chamber, and the waste gas combustion chamber is communicated with the gas outlet through second cavities among all the tube nests; each tube nest comprises a plurality of high-temperature heat exchange pipes and a plurality of low-temperature heat exchange pipes; and the high-temperature heat exchange pipes are arranged at the outlet end of the waste gas combustion chamber, and the low-temperature heat exchange pipes are arranged between the high-temperature heat exchange pipes and the gas outlet. The cost performance and market competitiveness of the waste gas incinerator are high; and a natural gas combustion chamber, the waste gas combustion chamber and the incinerator shell are stretchable on bases, the diameters of the waste gas combustion chamber and the incinerator shell can be reduced due to the natural gas combustion chamber, and the use amount of heat insulating materials is reduced, so the cost is saved; gases in the waste gas incinerator are fully mixed and combusted, and the incinerator has a good heat insulation effect.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a waste gas incinerator. Background technique [0002] Quite a lot of industrial production will produce waste gas, which is harmful to the human body and pollutes the atmosphere. Therefore, it is necessary to treat the waste gas into harmless gas and allow it to be discharged. A considerable amount of waste gas is a gaseous organic compound. The use of incineration technology is the best Common, effective, and lowest-cost exhaust gas treatment process. [0003] After searching, it is found that a waste gas incinerator disclosed in Chinese patent CN200420024060.9 includes a shell, a combustion chamber and a burner. The exhaust gas inlet leads to the inlet of the combustion chamber through the cavity between the tubes and the cavity between the inner wall of the shell and the outer wall of the combustion chamber; this exhaust gas incinerator realizes the use of combustion heat to p...
