Polymer polyol reaction waste gas absorption tower

The utility model relates to the technical field of waste gas absorption towers, and discloses a polymer polyol reaction waste gas absorption tower, which comprises a waste gas absorption tower, and the waste gas absorption tower comprises a tower body, a gas inlet, a gas outlet, a base, a medicament storage tank, a blow-off pipe, a mounting rack, a motor, a worm, a nozzle, a water pump, a drying cylinder, a mounting cylinder, a mounting plate and an electric push rod. According to the polymer polyol reaction waste gas absorption tower, the mounting plate, the electric push rod, the mounting cylinder and the drying cylinder are mounted, so that moisture in gas can be absorbed by the drying cylinder instead of a demister, and when replacement is needed, the mounting cylinder can be driven by the electric push rod to be lifted out of the exhaust port, and then the drying cylinder is directly taken out of the mounting cylinder; and the maintenance is more convenient. By mounting the mounting frame, the motor and
