 Activated carbon adsorption unit 
 A brief 
 ZH series of activated carbon adsorption of organic waste gas purification recovery management unit, is summed up my company Dowoson experience domestic and foreign similar products, improved design and manufacture. 
 This series of equipment, system design improvement, ancillary equipment, fully furnished, clean and high efficiency. In a leading position. It is widely used in petroleum, chemical, rubber, paint, coating, printing and other industries, where the release of benzene and other organic waste gas purification of exhaust gas can. It can effectively clean up the environment, eliminate pollution, to improve the working conditions of operation, to ensure that health workers, and to recover the organic solvent, lower production costs. 
 This series appliance is compact, small footprint, management, maintenance is simple, safe operation. 
 This product has been finalized four specifications (such as less than or greater than the specification can be designed): ZH-3000A / B, ZH-5000A / B, ZH-7000A / B, ZH-9000A / B (processing air volume of 3000 respectively. , 5000,7000,9000 m3 / h), points A and B a total of eight products. A type of single tank series, suitable for batch adsorption and regeneration; B-type double-tank series, suitable for continuous adsorption and regeneration.

 Third, the principle and process of adsorption purification 
 1, adsorption: 
 Solid organic waste through the filter to remove particulate matter, from the top down into the absorption tank, the organic matter is carbon capture, absorb and concentrate, purify the air from the tank through the lower part of the main fan into the atmosphere. 
 2, desorption 
 When the activated carbon adsorption of organic matter saturated, stop the inhalation of organic waste. Up into the activated carbon bed by steam stripping, activated carbon will be evicted from the organic matter, ie desorption. Can recover its activity in activated carbon, that is renewable. 
 3, hot air drying and cooling: 
 After desorption with steam activated carbon layer, leaving about 80 to 90% of the steam condensate, the hole filled with activated carbon, thereby reducing the activity of the carbon layer. Therefore, the pass into the hot air drying of the carbon layer. Then close the steam valve, and then pass into the air at room temperature, cooled to about 25 ℃, activated carbon recovery as ever, to prepare for recycling. 
 4, the organic solvent recovery: 
 The use of organic solvents with higher dew point temperature characteristics of the organic solvent mixture of steam and the introduction of the condenser to condensate, condensate through the trap into the separator, the use of solvents lighter than water features, separation and recovery. 
 5, the condensate water purification: 
 In order to ensure clean condensate, the condensate water to avoid organic solvents into the water, after the separation in the separator into the compressed air through the water, the organic solution in water full relief agent. Containing organic compounds by air expelled from the exhaust air return system, re-adsorption. Purified condensate, into the sewers. 
 6, continuous adsorption measures: 
 In continuous production plant in the corresponding continuous adsorption system also need to work in the exhaust gas purification system design, selection of two-tank series, so that adsorption and regeneration alternating continuous use. 
 7, the regeneration cycle: 
 Regeneration cycle should be based on the purified exhaust gas concentrations may be harmful. When harmful gas concentrations close to exceeding the value, that should stop adsorption, regeneration. The initial phase of the system work to help determine the need for timely outlet harmful gas concentrations in order to master a reasonable adsorption regeneration cycle.
