Single-stage activated carbon adsorption box

The utility model discloses a single-stage activated carbon adsorption box which comprises a box body, an inlet with a flange and an integrated structure are arranged at the bottom of the box body, and an outlet with a flange and an integrated structure are arranged at the top of the box body; the partition plate is arranged in the box body, an inner cavity of the box body is divided into two single-stage adsorption cavities through the partition plate, and when one single-stage adsorption cavity is in an open state and the other single-stage adsorption cavity is in a closed state, the upper partition plate and the lower partition plate abut against the partition plate, so that the adsorption box in the single-stage adsorption cavity on the side is located in the closed space. When the adsorption box in the closed space is detached and replaced, the access door is conveniently opened through a hinge, and the adsorption box is moved out of the box body from the box taking opening, so that new activated carbon
