Activated carbon adsorption box is mainly used to treat organic waste gas with large air volume low concentration. Activated carbon adsorbent can treat purify a variety of organic inorganic pollutants: benzene, alcohol, ether, alkane their mixed organic waste gas, acid waste gas alkaline waste gas; it is mainly used in manufacturing, smelting, chemical industry, machinery, electronics, electrical appliances, paint, shoe making, rubber, plastic, printing desulfurization, purification of harmful waste gas produced by various industrial production workshops.
The exhaust gas is powered by a fan, enters the activated carbon adsorption box under positive negative pressure, which contains a certain amount of activated carbon. Due to the unbalanced unsaturated molecular attraction chemical strength on the solid surface of activated carbon, when the solid surface contacts with gas, it can attract gas molecules to concentrate maintain on the solid surface, pollutants are adsorbed. After the exhaust gas is adsorbed filtered by the filter, the clean gas is discharged at high altitude, the saturated activated carbon can be recycled reduced. Cost.
How to calculate the size of activated carbon adsorption box according to the air volume?
The gas flow rate of adsorption layer of activated carbon adsorption device should be determined according to the form of adsorbent. For example, when using granular adsorbent, the gas flow rate should be less than 0.60m/s; when using fibrous adsorbent (activated carbon fiber felt), the gas flow should be less than 0.15m/s; when using honeycomb adsorbent, the gas flow should be less than 1.20m/s.
Activated carbon adsorption box commonly used materials are PP, carbon steel, stainless steel
Activated carbon pretreatment: granular activated carbon should be immersed in clean water, then washed into the filter, washed to remove dirt, lined with rubber lining can be immediately put into the filter. 5% HCl 4% NaOH solution were used for one treatment alternately, the flow rate was 10 meters per hour, the dosage was about 3 times of the volume of activated carbon, then washed to neutral after treatment.
Normal operation: open the upper drain valve inlet valve. After the upper drain valve discharges water, open the outlet valve, then close the upper drain valve.
