Zeolite Fixed Bed+Catalytic Combustion Equipment (RCO)

1、 Process Principle of Zeolite Fixed Bed+Catalytic Combustion Equipment

Firstly, use zeolite module to adsorb and compress volatile organic waste gas (VOCs) to improve the concentration;

Desorption of high-concentration waste gas molecules and sending to catalytic oxidation furnace for flameless combustion, decomposition into CO2 and H2O, so as to purify organic waste gas.

2、 Process Flow of Zeolite Fixed Bed+Catalytic Combustion Equipment

The volatile organic waste gas (VOCs) with large air volume and low concentration is filtered by the filter under the action of the induced draft fan, and then enters the zeolite fixed bed adsorption module for adsorption and concentration. The clean air after being absorbed and purified by the zeolite is discharged into the atmosphere through the chimney.

With the increase of time, the adsorption capacity of zeolite approaches saturation. The electronic control system controls the catalytic oxidation furnace to start heating and preheat the noble metal catalyst. The heated high temperature gas is cooled by the heat exchanger and then adjusted to 180~220 ℃ by air mixing to heat and desorb the saturated zeolite module. The desorbed high concentration organic waste gas is preheated by the heat exchanger and sent to the catalytic oxidation furnace for decomposition.

The organic waste gas heated to 250~350 ℃ in the catalytic oxidation furnace will burn without flame under the action of precious metal catalyst. The organic waste gas will be oxidized and decomposed into CO2 and H2O to achieve the purpose of purification. The purified air will be discharged to the high altitude through the chimney.
