The utilization rate of sieving cylinder declines, and increases the occupancy in place.Chinese patent CN201534043U provides a kind of rotary
Adsorption/desorption integration organic waste gas treatment device realizes continuous adsorption/desorption using the form of rotation activated carbon adsorption cylinder
Operation, improves exhaust-gas treatment ability, occupied area is small.Since its single absorbing cylinder configuration flexibility is poor and active
Charcoal itself there are the drawbacks of, with the increase of tubular structure diameter, waste is bigger when filling adsorption material, and gas flow pattern tends to
Turbulent flow is unfavorable for improving adsorption cleaning efficiency；Absorbing cylinder weight is significantly increased, and driving load is gradually increased, and energy consumption increasing etc. is asked
Topic limits application.In addition, there is also use that adsorbent material cannot be cooled down when elevated temperature desorption gas to guarantee to take off for its technical solution
Attached adsorption capacity, desorption gas channel, which are set to inside tubular structure, leads to not meet the problems such as increasing desorption process object.
