Description

TECHNICAL FIELD

[0001] The utility model relates to environmental protection equipment technical field, concretely is plastic industry tail gas catalytic combustion equipment. BACKGROUND

[0002] The catalytic combustion equipment is an environmental protection equipment for treating industrial organic waste gas, which utilizes a catalyst to reduce the combustion temperature of the organic waste gas and accelerate the oxidative decomposition of the organic waste gas. The working principle of the catalytic combustion equipment is to utilize a catalyst to reduce the combustion temperature and accelerate the rapid oxidation of harmful gas. Before entering the combustion chamber, the waste gas is preheated by a heat exchanger and then conveyed to the combustion chamber, and heated to the reaction temperature in the combustion chamber. The oxidation reaction is carried out in the catalytic reactor. The purified waste gas releases most of the heat through the heat exchanger, and then is discharged to the atmosphere through a chimney.

The filter chamber pre-treats the waste gas. The gas storage chamber stores the waste gas and controls the discharge rate of the waste gas. The mixing tank mixes the waste gas and air. The nitrogen chamber prevents the catalytic combustion chamber from exploding. The safety tank prevents high-temperature gas from directly contacting the waste gas source. After the organic waste gas is burned and purified, the temperature is relatively high. The cooling device cools the waste gas. The concentration detector detects the content of organic matter. After the content meets the standard, the waste gas can be discharged. The PLC control system controls the entire treatment process of the organic waste gas.
