Description

Technical field: [0001] The invention belongs to the technical field of activated carbon preparation, and relates to a preparation device for residual energy recovery type activated carbon. The prepared biomass granular activated carbon has excellent adsorption performance and high mechanical strength, and can replace coal-based activated carbon for water treatment and coal-fired flue gas decontamination. and ambient air purification. Background technique: [0002] Among various flue gas treatment techniques, activated carbon adsorption is a general technique capable of adsorbing every impurity in flue gas, including SO 2 , NOx, soot particles, mercury, dioxins, furans, other heavy metals, volatile organic compounds and trace elements. The cost of high-quality coal columnar granular activated carbon is high, and the price is expensive. It is a desulfurizer that is "as expensive as gold". Biomass raw material charcoal includes wood charcoal, bamboo charcoal, coconut shell c...

Problems solved by technology

[0003] At present, in the process of producing activated carbon with high mechanical strength from agricultural waste at home and abroad, the pyrolyzed or activated straw powdery carbon is pressed into columnar particles using grape juice or papermaking slurry as a binder, and activated again. Granular activated carbon is obtained, which has excellent adsorption performance, but the production process is relatively complicated, and the quality of the prepared activated carbon is not good, the cost is high, the relative density is low, and the thermal efficiency is low
