As one of the means of harmless waste treatment, incineration method can quickly realize the reduction of waste, harmless and recycling, so it has been more and more widely used in China.

In the process of waste incineration, toxic organic compounds such as dioxins are inevitably produced, which causes environmental pollution problems.

Activated carbon powder injection combined with bag dust collector (ACI+ BF) is an effective and widely used method to control dioxin emission from incinerator flue gas. bulk activated carbon pellets 

In order to provide reference and theoretical basis for the preparation and selection of activated carbon for the adsorption of dioxins, this paper carried out a study on the combined technology of activated carbon injection and double bag dust collector, the characteristics of activated carbon adsorption for dioxins and the influencing factors of activated carbon adsorption for dioxins.The adsorption and desorption isotherms of 13 kinds of commercial activated carbon were determined by low temperature nitrogen adsorption method, and the physical structures of activated carbon were calculated according to BET, T-Plot, BJH and DFT theory, and the iodine value and methylene blue value of 4 kinds of activated carbon were detected.activated carbon distributors  

The physical structure characteristics of activated carbon were analyzed in detail to prepare for the subsequent experiment. the influence of wood particle size. When the particle size of wood chips in the production of powdered activated carbon is 6~40 mesh, the particle size of wood chips has no obvious effect on the product quality. The effect of sawdust particle size on product quality is related to the zinc chip ratio used. When the zinc chips are relatively small (such as 80%), the wear resistance and relative density of activated carbon decrease with the increase of sawdust size. When the size of zinc chip is large (e.g. 200%), the wood chip particle size is 0.25~2.0mm, and the wear resistance and relative density of activated carbon are not significantly affected
