Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] Such as figure 1 As shown: the present invention includes a circulating fluidized bed adsorption device 1, a gas-solid separator 11, a VOCs-containing gas inlet 12, a gas outlet 13, an adsorbate inlet and outlet 14, a regeneration device 2, a bag filter a3, a fan a4, and an incineration device 5. Bag filter b6, fan b7. Waste gas containing high, medium and low concentrations of VOCs enters the circulating fluidized bed adsorption device 1 through the VOCs-containing gas inlet 12, and the adsorbate with adsorptive properties enters the circulating fluidized bed adsorption device 1 through the adsorbate inlet and outlet 14, and the circulating fluidized In the bed-type adsorption device 1, after the gaseous state of the VOCs-containing waste gas is in close contact with the adsorbate with adsorption capacity, it is transformed into an adsorbate that carries organ...
