Polishing is a common production process, and is one of surface modification techniques, and usually selects a corresponding polishing mode, a polishing tool and a polishing material according to the surface requirements of a product. Generally, a processing method for changing physical properties of a material surface by friction by means of a rough object (sand paper containing particles of higher hardness, etc.), mainly for the purpose of obtaining a specific surface roughness. Dust is often generated in the grinding process, is suspended or covered on a station, not only influences the health of the operation station, but also has the possibility of catching fire or explosion when the dust is accumulated to a certain degree, and is a very serious potential safety hazard. In order to improve the environment of a grinding station, a dust removal device is often required to be arranged at the station so as to remove dust generated by grinding as soon as possible.

Currently, common dust removal devices can be divided into two main categories: 1) a dry dust collector: comprises a gravity settling chamber, an inertial dust collector, an electric dust collector, a bag-type dust collector and a cyclone dust collector. 2) A wet dust collector: comprises a Venturi scrubber, a spray tower, a packed tower, a sieve plate tower and a rotational flow plate tower.

In addition, dust explosion can produce some toxic substances. Insufficient combustion results in the generation of carbon monoxide, and dust of the explosive itself also generates toxic substances, which sometimes causes fatal harm to workers at the production site, so that a new or improved technical solution is urgently needed to solve the technical problems.
