Dust Control of Coal Yard

In the coal power plant, there would be dust in some place. The dust is resulting from the raising dust with wind blowing and handling coal of bucket wheel machine. In generally, there would be three methods of avoiding dust. The first one is spray dust-removal in sealing house, but the cost is high. The second one is adopting wind break wall, with disadvantage of high cost. The third one is using the spray gun to remove the dust, with advantage of low cost and high efficiency. However, there will be a problem of prior-period investment. If choosing large spray gun, the range and cover area is large. The quantity of large spray gun is less than small spray gun. However, the large spray gun has larger volume. The price of the large spray gun is higher than small spray gun. To balance this contradiction is difficult and important. The most important thing is the design of the spray gun, which needs designer to consider the earlier investment and the low cost factor. The spray gun is easily influenced by wind power. The best solution is that the wind break wall is added outside of the spray dust-removal equipment.
In this way, the stacker reclaimer and belt conveyor could convey the coal to the fixed destination without much dust. This is an important measure for protecting the environment.
