Application And Scope
The equipment is suitable for treating organic waste gas at room temperature, with high air volume and low to medium concentration, especially for the treatment of volatile organic solvents such as benzene, ester, aldehyde, ether, alkane and mixed types.
It is widely used in industries, including automotive, shipbuilding, motorcycle manufacturing, furniture, home appliances, piano production, and steel structure factories. It is particularly effective in purifying organic waste gases in painting and coating workshops or production lines. Furthermore, it can be integrated with production lines for shoe adhesive, printed iron cans, chemical plastics, printing inks, cables, and enameled wire.
Technical Features
The equipment adopts the combination of adsorption concentration and catalytic combustion processes, with a closed loop for the entire purification and desorption process. Compared with recovery-type organic waste gas purification equipment, it does not require additional energy such as steam, and the operation process does not produce secondary pollution, resulting in low equipment investment and operating costs.
Specially shaped honeycomb activated carbon is used as the adsorption material, with a long lifespan, low resistance, and high purification efficiency. The precious metal palladium and platinum are used as catalysts loaded on honeycomb ceramics, with a catalytic combustion rate of over 97%. The catalyst has a long lifespan, low decomposition temperature, short desorption preheating time, and low energy consumption. The equipment uses a centralized microcomputer control system with fully automated operation and stable and reliable operation.
The front-end adopts a dry high-efficiency dust filtration device, with high purification efficiency, ensuring the lifespan of the adsorption equipment. The equipment is equipped with complete safety facilities, with safety and fire valves (optional) installed between the gas source and the equipment. During desorption, the desorption temperature entering the activated carbon bed is strictly controlled, and protection measures such as flame retardants, temperature sensors, alarms, and automatic shutdowns are in place. The equipment is equipped with a nitrogen generation unit, which is the first of its kind in China, increasing its safety factor.
It can be used to purify and treat organic waste gas produced by continuous or batch production.
Working Principle
The equipment uses a combination of activated carbon adsorption, thermal air low desorption, and catalytic combustion to purify organic waste gas. It utilizes the characteristics of multiple micropores and huge surface tension of activated carbon to adsorb organic solvents in the waste gas, thereby purifying the discharged waste gas as the first working process.
After the activated carbon adsorption is saturated, the organic solvents adsorbed on the activated carbon are desorbed and sent to the catalytic combustion bed in a certain concentration ratio by a thermal airflow, which is the second working process. The high-concentration organic waste gas entering the catalytic combustion bed is decomposed into carbon dioxide and water under the action of oxygen by the catalytic reaction. The heat released during the decomposition is recovered by the high-efficiency heat exchanger and used for heating the high-concentration organic waste gas entering the catalytic combustion bed, which is the third working process.
After running for a certain time and reaching a balance in the three working processes mentioned above, the desorption and catalytic decomposition processes do not require external energy heating.
