In summer, cold air can be provided to improve the working environment and increase the comfort of workers. The air supply port 5 is a drum-shaped air port, which has the function of adjusting the air supply direction and the characteristics of long air supply distance, which can ensure that fresh air is delivered to the work station. The smoke purifier is composed of various modules assembled as a whole. A single module can smoothly enter the interior of the mechanical cabin 7 through the cabin door and be assembled inside.At this time, the purification section module 601, the cleaning section module 602, the backblowing module 603, and the fan section module 604 are arranged on the same side of the upper and lower sides of the purification section module 601 and the cleaning section module 602 through the segment connectors 614, bolts, and nuts.

The purification section module 601 and the backblowing module 603 are arranged side by side, and the fan section module 604 and the cleaning section module 602 are arranged and installed side by side. After assembly, the dust-containing gas enters through the top air inlet 605, enters the purification section module 601, and is filtered by the filter element. At the same time, the blowing port of the backblowing module 603 blows compressed air to the filter element to allow the dust to fall fully, and compressed air backblowing is performed to shake the dust adsorbed on the filter cartridge 611 off to the cleaning section module 602. The dust falls into the dust cleaning bag 612 below the ash hopper, and the clean gas filtered by the filter element is discharged into the interior of the machinery cabin 7 through the fan B 610 and the air outlet louver 607.
