Then, comprehensively examines the activated carbon pore structure of mainstream smoke particles with phase content in the conventional chemical composition is the relationship between the filtration efficiency, found that adding activated carbon can be reduced in different degrees in cigarette mainstream smoke conventional component content, and under the condition of the same dosage of activated carbon, the ternary composite way of flue gas composition of conventional filtration efficiency higher than binary compound mode. In the process of adsorption of flue gas components, the specific surface area of activated carbon with different pore structures determines its total adsorption capacity, and the pore size distribution affects its adsorption selectivity. The contents of total particulate matter, nicotine, moisture and tar in the mainstream smoke of cigarettes all increased stably with the increase of the number of suction outlets. In the process of cigarette smoking, the filtration efficiency of activated carbon with different pore structure to the conventional components of smoke changed dynamically with the increase of the number of suction ports. Qualitative description method was used to evaluate the sensory quality of activated carbon cigarettes. It was found that the addition of activated carbon increased the smoke suction resistance, reduced the smoke concentration and aroma, reduced the irritation, and had no obvious peculiar smell and discomfort, and had no negative effect on the sensory quality of cigarettes. conditions:Treatment air volume :Q=20000 m'h, design temperature is 35° C, pressure is 1.01325×103Pa  Since the proportion of air in exhaust gas is far greater than that of pollutants, the properties of exhaust gas can be approximately viewed as the thermophysical properties of dry air. Please refer to Appendix 9 of Principles of Chemistry to obtain the following data:Properties of air mixture:Fluid density P;=1.147kg/ m', viscosity u,= 1.94×10-5 Pa.S, specific heat capacity C,=1.005kJ/(kg."C)activated charcoal pellets bulk
Used for gas phase adsorption of activated carbon: benzene, toluene, xylene, acetone, oil and gas, CS, and other organic solvents adsorption and recovery, cigarette filter, decoration in addition to taste, indoor air purification (formaldehyde, benzene removal), Industrial gas purification (such as CO, N, etc.), petrochemical industry production, natural gas purification, desulfurization, deodorization, waste gas treatment, biochemical, paint industry, underground places. Leather factory, animal feeding places of air purification, deodorization, flue gas odor adsorption, sulfide adsorption, mercury vapor removal, reduce the generation of dioxin.www.wyactivatedcarbon.comThe products of these activated carbon plants can be roughly divided into three categories:
One is the use of low temperature coking (blue carbon plant) by-product of small "coke slag", directly into the Slip activation furnace for steam activation, the production of iodine value of 500 to 700mg/g, ash content is not higher than 8%, strength of only 65 to 80%, bulk density of 350-380g /L granular carbon, Sell to other professional activated carbon factory or ask business processing into powdered activated carbon products;
