Technological Principle

The device is designed on the basis of two basic principles of adsorption (high efficiency) and catalytic combustion (energy saving). It works continuously with two gas paths, one catalytic combustion chamber and two or more adsorption beds alternately. The organic exhaust gas is first adsorbed by activated carbon, and then desorbed by hot air to regenerate activated carbon. The desorbed organic matter has been concentrated (the concentration is more than ten times higher than the original) and sent to catalytic combustion chamber for carbon dioxide combustion and water vapor discharge. 。 When the concentration of organic waste gas is over 2000 PPm, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating. After combustion, part of the exhaust gas is discharged into the atmosphere, and most of it is sent to the adsorption bed for regeneration of activated carbon. In this way, the thermal energy required for combustion and adsorption can be satisfied, and the purpose of energy saving can be achieved. After regeneration, the activated carbon can enter the next adsorption; during desorption, the purification operation can be carried out in another adsorption bed, which is suitable for both continuous operation and intermittent operation.

purpose

The purifying device of motor assembly line is mainly used to purify and eliminate harmful organic waste gas volatilized or leaked from painting, printing, electromechanical, household appliances, shoe-making, plastics and various chemical workshops. Powder coating line is suitable for organic waste with low concentration, which is not suitable for direct combustion or catalytic combustion and adsorption recovery. Satisfactory economic and environmental benefits can be obtained for air, especially for the treatment of large air volume.

Performance and characteristics

1. The equipment has advanced design principle, unique material, stable performance, simple structure, safety and reliability, energy saving and power saving, and no secondary pollution. The equipment covers a small area and is light in weight. The adsorption bed adopts a drawer structure, which is convenient for filling and replacement.

2. The honeycomb bulk activated carbon, a new type of activated carbon adsorption material, is suitable for use in high air volume.

3. Noble metal catalysts supported on honeycomb ceramics have low resistance and high activity in catalytic combustion chamber.

4. Activated carbon bed adsorbing organic waste gas is desorbed and regenerated by hot air after catalytic combustion, and the desorbed gas is sent to catalytic combustion chamber for purification without external energy, with low operating cost and remarkable energy saving effect.
