Self-preheating waste gas incinerator

Abstract

The utility model discloses a self-preheating waste gas incinerator which comprises an incineration chamber. A diaphragm is arranged in the incineration chamber, the inlet of the incineration chamber is communicated with a preheating pipe, the preheating pipe is sleeved outside the incineration chamber, the outlet of the incineration chamber is communicated with a heat exchanger, and a gas exhaust hole is respectively arranged at the high temperature outlet and the high temperature inlet of the heat exchanger. The utility model has the advantages of reasonable design, simple structure, favorable waste gas treatment effect, high waste gas purification rate through actual detection, small utilization stroke for heat energy recovery and little heat energy loss, saves a set of independent preheating device through a spontaneous preheating structure design, reduces the energy consumption on the basis of ensuring the preheating effect, can more sufficiently decompose the waste gas after preheating, can secondarily recover the heat energy, greatly enhance the recovery efficiency and efficiently save the energy.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a self-preheating 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 a harmless gas before allowing 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. The incineration process will generate a lot of heat while processing the waste gas. The waste gas incineration equipment will be equipped with some heat energy recovery devices. At present, the heat energy recovery and utilization device of the common waste gas incineration equipment is to pass the high-temperature gas after incineration through a hot water tank, and use heating Water is used to recover hea...

Problems solved by technology

The incineration process will generate a large amount of heat while processing the waste gas. The waste gas incineration equipment will be equipped with some heat energy recovery devices. At present, the common heat energy recovery device of the waste gas incineration equipment is to pass the high-temperature gas after incineration through a hot water tank, and use heating Water is used to recover heat energy. The biggest disadvantage of this recovery method is that the recovery rate of heat energy is not high.

Part of the exhaust gas incineration treatment device directly enters the incineration chamber without preheating. A large amount of low-temperature exhaust gas entering the incineration chamber will cause the incineration room temperature to be too low and the exhaust gas incineration treatment is insufficient. Most of the exhaust gas incineration treatment devices are additionally preheated device, high energy consumption, large investment, complex structure
