AI Technical Summary
Existing chemical waste gas incinerators release heat along with the waste gas during the incineration process, resulting in energy waste.
A chemical waste gas incinerator was designed, comprising heat exchange coils and a scrubbing system. Waste gas is transported to the incinerator body through a gas transmission pipe for incineration. The incinerated waste gas is then pumped into the pipe body for heat recovery, then comes into contact with the cleaning liquid through an aeration pipe and is stirred by stirring blades, and finally undergoes secondary scrubbing through a spray pipe.
It enables the recovery and utilization of heat after chemical waste gas incineration and multiple washing processes, reducing energy waste and improving the efficiency and effectiveness of waste gas treatment.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In use, this utility model transports chemical waste gas to a heat exchange coil via a gas transmission pipe, and then the heat exchange coil transports the chemical waste gas to the incinerator body. The gas is then burned by the flame ignited by the burner. The incinerated chemical waste gas is then transported to the pipe body via a first connecting pipe under the action of a delivery pump, and then output from the second connecting port by the delivery pump. The waste gas, which is heated by combustion in the pipe body, heats the chemical waste gas in the heat exchange coil, which is beneficial for energy recovery and utilization.
