Exhaust deodorization adsorption equipment, activated carbon adsorption purifier role
Equipment construction
The adsorption tower is composed of four parts: an upper box body, a lower bracket, a working ladder, a platform guardrail and a discharge device.
Activated carbon tower type can be designed as: magazine type, horizontal type, drum type. Material can be made using SUS304, SS41, PP, etc.. Commonly filled with activated carbon coconut shell and coal activated carbon, internal anti-corrosion treatment
Activated carbon is an adsorbent material widely used in industrial waste gas and wastewater treatment at present. There are two research focuses on activated carbon: one is the development of activated carbon with special properties, such as fiber activated carbon and wood activated carbon; two is the modification of activated carbon pore structure adjustment, improve the ability to absorb specific adsorbates or reduce the desorption requirements. Commonly used activated carbon modification methods include oxidation, reduction, loading of heteroatom and compounds, etc.. The wet activated oxidation of coconut shell activated carbon by H2O2 and concentrated HNO3 can enhance the adsorption capacity of activated carbon to benzene. Purification of activated carbon was modified by acid and alkali, can improve the selective adsorption of volatile organic compounds. The treatment of activated carbon with high boiling point material reduces the requirement for desorption conditions of activated carbon.
Activated carbon adsorption tower work process: first of all, the hot flue gas scrubber, with saturated ammonium sulfate solution, the flue gas cooling process, at the same time, due to the evaporation of water saturated ammonium sulfate solution and precipitation of ammonium sulfate crystal. Cooling flue gas sulfur dioxide absorption tower by demister. In the absorption tower, ammonia ammonia and water mixture. Sulfur dioxide absorption in flue gas, ammonia reaction to produce ammonium sulfate. Finally, activated carbon after the chimney 120 meters high smoke into the atmosphere. Ammonium sulfate solution was sent to the recovery tower. Process of washing tower of ammonium sulfate pulp dehydration system. First by hydraulic cyclone and dewatering, then by ammonium sulfate centrifuge cake. From the cyclone recovery solution and centrifuge scrubber, recycling. Ammonium sulfate filter cake was sent to the granulation system, a high value granular ammonium sulfate fertilizer that was taken away by train or truck prior to storage in a storage can accommodate 50000 tons of ammonium sulfate dome.
Process characteristics of glass fiber reinforced plastics activated carbon tower
1. Double alkali activated carbon tower is sodium alkali as absorbent, high reactivity, rapid absorption, can reduce the gas-liquid ratio, thereby reducing operating costs, and can reduce investment in water tanks, pumps and pipelines;
2. Use lime neutralization precipitation, sodium alkali regeneration recovery, less waste, low operating costs;
3 shows. Absorption process without wastewater discharge in normal operation;
4 shows. Precipitation separation and reliable, can greatly reduce investment;
5. Activated carbon slag non-toxic, minimum solubility, no two pollution, comprehensive utilization;
6. Easy to operate, stable system can run for a long time
