Description
Technical Field

Background
The activated carbon with good adsorption performance is widely applied to the adsorption of harmful gases in air purification, and the most widely applied to the treatment of organic waste gases including VOCs is a honeycomb activated carbon product.
The porous structure of the activated carbon has extremely high specific surface area and better adsorption capacity to organic gas, the structure of the honeycomb activated carbon also has larger overfire air contact area under smaller overall dimension, but a certain proportion of bonding materials and other auxiliary materials need to be added into the activated carbon powder in the manufacturing process of the honeycomb activated carbon to meet the requirement of extrusion molding, if the addition proportion of the bonding materials and the auxiliary materials is too large, the adsorption efficiency of the honeycomb activated carbon is reduced, but the strength of a finished product is reduced if the addition amount is too small, the damage in transportation and use is easily caused, and particularly when the honeycomb activated carbon is regenerated in an off-line desorption mode, the breakage rate is greatly increased by repeated assembly, disassembly and transportation, so the contradiction between the adsorption efficiency of the honeycomb activated carbon and the structural strength exists all the time.
Furthermore, the honeycomb activated carbon is easy to cause fire accidents during desorption and regeneration, and the reason is that exothermic reaction is generated in the process of activated carbon reabsorption, and particularly when organic waste gas with low burning point (such as ketone and aldehyde gas) is treated, spontaneous combustion is easily generated to cause fire if the heat dissipation is poor, so that only hot air temperature below 120 ℃ can be used for ensuring safe desorption, and the low desorption temperature is difficult to completely desorb organic solvent with high boiling point, so that the adsorption capacity after honeycomb activated carbon regeneration is gradually reduced, and the service life of the honeycomb activated carbon is reduced.
The zeolite rotating wheel used in the current market can be desorbed by high-temperature hot air, but the price is very high, and the zeolite molecular sieve has a narrow application range to organic waste gas types compared with activated carbon, so the zeolite rotating wheel cannot be generally applied in the market.
