Firstly, use the activated carbon module to absorb and compress volatile organic waste gas (VOCs) to increase 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.

Strong>II.Process flow of activated carbon adsorption+catalytic combustion equipment (RCO)

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

With the extension of time, the adsorption capacity of activated carbon is close to saturation. The electronic control system controls the catalytic oxidation furnace to start heating and preheat the precious metal catalyst. The heated high temperature gas is cooled by the heat exchanger and then adjusted to 100-120 ℃ by air mixing to heat and desorb the saturated activated carbon module. The desorbed high concentration organic waste gas is preheated by the heat exchanger and sent to the catalytic oxidation furnace for decomposition. (

The concentration of organic waste gas can reach 10-15 times, which is more suitable for treatment of organic waste gas with large air volume and low concentration;

It only takes 15-30 minutes to raise the temperature to the ignition temperature when the equipment is started, so the energy consumption is low;

The honeycomb catalyst impregnated with precious metal palladium and platinum is adopted, with large surface area, small resistance and high purification rate;

The system waste heat can be returned to the drying channel to reduce the power consumption in the original drying channel, and can also be used as a heat source in other aspects;

Generally, the catalyst is replaced in five years, and the support is renewable, with long service life;

The outside of the equipment is at normal temperature, with high safety and purification efficiency of over 95%;

The electric heating mode is adopted to support combustion, which is simple and convenient;

Fully automatic PLC control is realized throughout the operation process, which is convenient and reliable.

4、 Application scope of activated carbon adsorption+catalytic combustion equipment (RCO)
