Example of using catalytic combustion:

The surface coating waste gas of metal and plastic parts in the automotive, motorcycle, and bicycle industries is collectively referred to as spray painting (coating) organic waste gas treatment.

With the continuous improvement of people's lives and the continuous development of the economy, the environment has been deteriorating, and air and water pollution have become increasingly serious. In recent years, the tension of air pollution has been exacerbated, and many areas have experienced varying degrees of acid rain hazards, even glacier melting, causing people's living air to continuously deteriorate and leading to various diseases. The surface coating exhaust gas of metal and plastic parts in the automotive, motorcycle, and bicycle industries, collectively referred to as spray painting (coating) organic waste gas treatment, commonly used activated carbon adsorption boxes, photocatalytic processes, and spray towers can meet emission requirements, but they cause secondary pollution and increase the cost of solid waste treatment.

1. Fully automatic control, easy to operate.

2. The device has advanced principles, high-quality materials, stable performance, easy operation, energy-saving and labor-saving, safe and reliable, and no secondary pollution;

3. Low energy consumption and low operating costs. Only the fan power is used for adsorption, with a short desorption time of 2-4 hours and a long cycle of 2-4 days.

4. The activated carbon adsorption bed that adsorbs organic waste gas can recycle the hot gas after catalytic combustion for desorption and regeneration. The desorbed gas is then sent to the catalytic combustion chamber for purification treatment without the need for external energy, resulting in low operating costs and energy savings.

5. Adopting a new type of activated carbon adsorbent material - honeycomb activated carbon, it has * kinetic performance compared to granular activated carbon. Extremely suitable for use under high air volume.

Working principle of catalytic combustion equipment for organic waste gas treatment:

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.

Organic waste gas activated carbon adsorption catalytic combustion device

Organic waste gas treatment catalytic combustion process flow:

Organic waste gas pretreatment → Organic waste gas activated carbon adsorption → Organic waste gas desorption → Organic waste gas concentration catalytic combustion purification

Activated carbon adsorption desorption catalytic combustion effectively combines the advantages of activated carbon regeneration. Firstly, use activated carbon for adsorption. When the adsorption is saturated, start the catalytic combustion equipment and use hot air to locally heat the activated carbon adsorption bed. When the catalytic combustion reaction bed is heated to 200 ℃ -350 ℃ and the activated carbon adsorption bed locally reaches 50-100 ℃, the desorbed high concentration waste gas can be oxidized and decomposed in the catalytic reaction bed. The high-temperature gas after the reaction undergoes heat exchange in the heat exchanger, and a portion of the heat exchanged gas is sent back to the activated carbon adsorption bed for desorption, while the other portion is directly discharged.
