The activated carbon adsorption box filtration system is more suitable for the treatment of high-volume and low-concentration exhaust gas in exhaust gas treatment equipment. The activated carbon adsorption box has the advantages of high adsorption efficiency, wide application, convenient maintenance, and can treat multiple mixed exhaust gases at the same time. Activated carbon can remove formaldehyde. Activated carbon adsorption box is widely used in the production of electronic components, battery (battery) production and other waste gas generating places.
Activated carbon adsorption box device structure composition
Activated carbon adsorption purification device, desorption purification device, adsorption fan, desorption fan and other components.
Scope of application of activated carbon adsorption box device
The device is used in the treatment of organic waste gas with high air volume and low concentration. It can treat benzene, ketones, alcohols, alkanes and their mixed organic waste gas. It is mainly used in chemicals, machinery, electronics, electrical appliances, painting, and shoemaking. , Rubber, plastics, printing and the purification treatment of harmful waste gas generated in various industrial production workshops.
The activated carbon adsorption box uses the surface force of the high-performance activated carbon adsorbent solid itself to attract the adsorbate of organic waste gas molecules to the surface of the re-adsorbent, which can adsorb the waste gas of organic solvents such as benzene, alcohol, ketone, ester, gasoline, etc. It is more suitable for the treatment of high-volume and low-concentration exhaust gas, and is suitable for industries such as electronics, chemical industry, light industry, rubber, paint, painting, printing, machinery, ships, automobiles, and petroleum.
Working principle of activated carbon adsorption box device
Adsorption process: Due to the unbalanced and unsaturated molecular gravitation or chemical bonding force on the solid surface, when the solid surface is in contact with gas, it can attract gas molecules to concentrate and maintain them on the solid surface. This phenomenon is called For adsorption.
Using the adsorption capacity of the solid surface, the exhaust gas is in contact with the porous solid material on the large surface, and the pollutants in the exhaust gas are adsorbed on the solid surface to separate it from the gas mixture to achieve the purpose of purification.
Performance characteristics of activated carbon adsorption box device
No secondary pollution occurs during operation; equipment investment is low, operating costs are low; stable performance, can treat multiple mixed gases at the same time, purification efficiency ≥95%; new activated carbon adsorbent is used as adsorbent, which has low resistance, long life, The advantages of high purification efficiency; the activated carbon adsorption device can be customized according to the characteristics of waste gas treatment and customer needs.
The activated carbon adsorption device is a dry waste gas treatment equipment, which consists of a box and an adsorption unit packed in the box.
The main processing of activated carbon adsorption device includes three types
1. Acidic waste gas and acid mist (for example: NO2, H2SO4, HCL, HF, etc.);
2. Alkaline waste gas (for example: NH3, etc.);
3. Organic waste gas and odor (for example: benzene, phenol, alcohol, tincture).
Activated carbon adsorption device adsorption unit
It is the core component installed in the exhaust gas purifier. The adsorption unit is installed in a layered drawer in the equipment box, which can be easily taken out from the inspection doors on both sides. And the inspection door is easy to open and tightly sealed.
1. The inlet temperature of the exhaust gas of the device should be lower than 50℃. If the exhaust gas is higher than 50℃, an air cooling device should be added, and it will enter the adsorption tank after cooling;
2. For the purification of exhaust gas containing more particulate dust generated by painting operations, the exhaust gas should be filtered and purified first;
3. When the adsorbed organic solvent has a high boiling point (above 120°C), a steam filter can be used to increase the temperature of the desorption steam;
4. If there is no steam supply, a small electric steam generator can be specially equipped with the purification device.
