Abstract

This invention discloses an activated carbon adsorption tank with filter element replacement without downtime and continuous filtration function, belonging to the technical field of filtration equipment. The activated carbon adsorption tank includes a tank body, a filter element switching transmission mechanism, and two activated carbon filter elements. Two mounting slots are axially formed inside the tank body. The upper end of each mounting slot communicates with an air inlet mechanism, and the lower end penetrates the bottom of the tank body to communicate with the outside. The filter element switching transmission mechanism is located at the two mounting slots. The two activated carbon filter elements are positioned one-to-one inside the two mounting slots. The upper parts of both activated carbon filter elements are inserted into the filter element switching transmission mechanism, and the lower parts are snapped into the bottom of the tank body, with the lower ends of the mounting slots sealed accordingly. The filter element switching transmission mechanism enables seamless switching of the air path, allowing the activated carbon filter elements to continuously filter waste gas, and also improves the filtration efficiency of the activated carbon adsorption tank for waste gas.
