Technical Field

The utility model relates to the technical field of resin adsorption tanks, in particular to an adsorption regenerated resin adsorption tank.

Background

At present, organic waste gas treatment is carried out, and the method aims at single component of the treated waste gas, has recycling value and adopts an adsorption-solvent recycling technology.

The concentration of the waste gas to be treated is high, the boiling point of the main component is low, and the selection of the adsorption material is the key point of project treatment reaching the standard. The adsorbents commonly used in the industrial waste gas treatment include activated carbon, molecular sieve zeolite, activated alumina, and polymeric adsorbents. When the treatment effect of the activated carbon and the zeolite molecular sieve on the gases such as methylene dichloride and the like is not ideal, the functional polymeric adsorbent-adsorbent resin is recommended to be selected, and the adsorption effect of the functional adsorbent resin on the gases is particularly remarkable. The adsorption resin is characterized by adsorption and has a porous three-dimensional structure. The porous resin is newly developed in the polymer field in recent years, the specific surface area of the polymer multifunctional adsorption resin is large and is as high as 1200m < 2 >/g, and the adsorption resins with different pore sizes and different polarities can be selected according to the types of the adsorbed organic waste gas; the conventional adsorption material of the existing adsorption tank is granular carbon. The adsorption effect of the activated carbon is not obvious for some gases with special components, such as dichloromethane, and the adsorption effect of the adsorption resin on the dichloromethane is not obvious; traditional adsorption resin is required to be taken out to be cleaned after organic gas is adsorbed, and then the resin can be reused, so that the cleaning of the adsorption resin is inconvenient.
