technological process

1、 Principle Introduction

Designed based on the two basic principles of adsorption (high efficiency) and catalytic combustion (energy saving), it adopts dual gas path continuous operation, with one catalytic combustion chamber and two adsorption beds alternately used. Firstly, the organic waste gas is adsorbed onto activated carbon, and when it reaches saturation, the adsorption is stopped. Then, the organic matter is desorbed from the activated carbon using a hot gas flow to regenerate the activated carbon; The detached organic matter has been concentrated (with a concentration several tens of times higher than before) and sent to the catalytic combustion chamber for catalytic combustion into carbon dioxide and water vapor, which are then discharged. When the concentration of organic waste gas reaches 2000mg/m3 or above, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating. Part of the exhaust gas after combustion is discharged into the atmosphere, while the majority is sent to the adsorption bed for activated carbon regeneration. This can meet the heat energy requirements for combustion and adsorption, achieving the goal of energy conservation. After regeneration, it can enter the next adsorption; During desorption, purification can be carried out using another adsorption bed, which is suitable for both continuous and intermittent operations.

Scope of Application

The purification and elimination of harmful organic waste gases emitted or leaked from painting, printing, electromechanical, home appliances, shoe-making, plastic and various chemical workshops, as well as the elimination of odors, are most suitable for low concentration organic waste gases that are not suitable for direct combustion or catalytic combustion and adsorption recovery treatment, especially for high air volume and low concentration treatment scenarios, which can achieve satisfactory economic and social benefits.

3、 Main features

The device has advanced design principles, unique materials, stable performance, simple structure, safety and reliability, energy saving and labor-saving, and no secondary pollution. The equipment occupies a small area and is lightweight. The adsorption bed adopts a drawer type structure, which is easy to load and replace.

Low power consumption, the catalytic combustion chamber uses honeycomb ceramic shaped precious metal catalysts as carriers, with low resistance and high activity. When the concentration of organic waste gas exceeds 2000mg/h, spontaneous combustion can be maintained.
