The existing dust suppression device on the belt conveyor usually adds a spray device in the conveying process or at the exit to spray water into the dust removal space in the form of mist particles, so as to reduce dust pollution by means of water mist dust suppression. This method needs a lot of water resources.
Another way is to add a dust bag to the belt conveyor, which includes a body, a dust inlet, an air outlet, a flower board and a plurality of evenly distributed filter bags connected with the flower board. The dust falls back to the coal conveying belt after being filtered by the filter bag, which reduces the dust pollution of the coal conveying belt. However, this requires a supporting fan, and the filter bag needs regular maintenance and replacement. Usually, a coal conveying belt uses a large number of filter bags, which are frequently replaced and have high daily maintenance costs.
In addition to the above two dust-proof devices, Shenyu Electric also has a dust-proof device for coal conveyor-all-inclusive/liftable dust-proof cover for coal conveyor, which has won the national patent, and is energy-saving and environmentally friendly, and its operating cost is lower than one. The dust-proof cover device has a dust-proof effect of more than 95%, is simple and clean to clean, and is convenient to replace or maintain idler parts. Installing dust cover on coal conveying belt in coal-fired power plant not only solves the dust pollution caused by lignite belt transportation in coal-fired power plant and the noise pollution caused by belt conveyor, but also greatly reduces the fire hazard at coal conveying site.
