Air purification device

The utility model relates to the technical field of boiler slag removal, in particular to an air purification device which comprises a device body, a cooling mechanism is installed on the front side of the device body, a dust suction mechanism is connected to the rear side of the device body, the device body comprises a slag guide assembly and a slag discharge assembly, and the slag discharge assembly is arranged on the lower side of the slag guide assembly. The slag cooling device has the beneficial effects that the slag guide plate is a hollow metal plate easy to conduct heat, cooling water in the cooling mechanism can conduct cold and heat exchange with slag after entering the slag guide plate, so that the slag is cooled, the air inlet fan blows water mist generated by the cooling mechanism downwards, the water mist is combined with diffused dust, and the slag cooling effect is improved. Meanwhile, a dust collector provides suction force for a dust collection cover through a dust conveying pipe, so that th
