Overview

Utilizing the adsorption properties of activated carbon with multiple micropores to adsorb organic waste gas is an extremely effective industrial treatment method. Honeycomb shaped activated carbon has the advantages of stable performance, corrosion resistance, and resistance to high-speed airflow impact. Using it to adsorb organic waste gas can achieve a purification efficiency of up to 90-95%. After saturation of activated carbon adsorption, it can be regenerated by hot air desorption. After regeneration, the activated carbon is put back into use. By controlling the flow rate of the desorption process, the concentration of organic waste gas can be concentrated 10-20 times. The desorption gas flows through the combustion device of the catalytic bed and is heated to around 300 ℃. It is ignited under the action of the catalyst, and the purification efficiency of the catalytic combustion process can reach over 90%. After combustion, CO2 and H2O are generated and a large amount of heat is released. A part of this heat is used to heat the high concentration exhaust gas desorbed through the heat exchanger inside the catalytic combustion bed, and the other part is used as the desorption gas for activated carbon outside the heating chamber. Generally, to achieve the self equilibrium process of desorption catalytic combustion, the burner needs to be started for about 1 hour. After reaching thermal equilibrium, the electric heating device can be turned off. At this time, the regeneration treatment system relies on organic solvents in the exhaust gas as fuel to achieve self balancing circulation in the regeneration process without the need for external energy, greatly reducing energy consumption and eliminating secondary pollution. The entire adsorption and catalytic combustion process is automatically controlled by PLC.

Product Features

1. Low energy consumption

The catalytic ignition temperature is low, only 250-300 ℃, and the preheating time of the equipment is known, only 15-30 minutes. The high concentration consumption is only due to the efficiency of the fan, and automatic intermittent compensation heating is used when the concentration is low.

2. Low resistance and high purification rate

The honeycomb ceramic carrier catalyst impregnated with precious metals platinum and palladium has a large specific surface area and low resistance.

3. Waste heat recycling

Waste heat is used to preheat the exhaust gas to be treated, reducing the overall power consumption of the host.

4. Safe and reliable

The equipment is equipped with a flame retardant dust removal system, explosion-proof pressure relief system, over temperature alarm system, and fully automatic control system.

5. Long service life

The catalyst is usually replaced after 8000 hours, and the carrier is renewable.
