TECHNICAL FIELD

[0001] The utility model relates to flue gas treatment technical field especially, it is a kind of activated carbon adsorption device for medical waste incineration flue gas treatment. BACKGROUND

[0002] The flue gas generated in the medical waste incineration process is treated by the following process: the flue gas generated by incinerating medical waste in the incinerator is transported to the activated carbon adsorption equipment through the flue gas pipeline (heat exchange equipment is arranged on part of the flue gas pipeline to reduce the temperature of the flue gas), the pollutants in the flue gas are adsorbed by the activated carbon in the activated carbon adsorption equipment, and then the flue gas purified by the activated carbon adsorption equipment is discharged into the purification tower for further purification treatment, and finally the clean flue gas after treatment is discharged through the discharge chimney.

[0003] The activated carbon adsorption equipment in the medical hazardous waste incineration system mainly works by utilizing the adsorption characteristics of activated carbon, and its working principle includes: 1. adsorption, when the waste gas generated by medical hazardous waste incineration passes through the activated carbon device, harmful substances in the waste gas, such as organic compounds, heavy metal ions, odors, etc., will be adsorbed by the microporous structure on the surface of activated carbon. The large specific surface area and rich microporous structure of activated carbon provide a large number of adsorption sites, so that activated carbon can effectively adsorb harmful substances in waste gas; 2. purification: after the adsorption process, harmful substances in the waste gas are left on the surface of activated carbon, thereby achieving the purification of waste gas.

[0004] However, in the current activated carbon adsorption equipment, due to the problem of volume, the contact time between flue gas and activated carbon is short, so that the flue gas is difficult to contact with activated carbon for a sufficient contact time, and thus there is a hidden danger that the activated carbon cannot fully adsorb pollutants.
