摘要

Taking an open-air coal yard as an example, comparing the effects of different setting methods of the windbreak net on the dust formation in the open-air yard, the results show that when the windproof net is of “mouth” type, the effect of dust suppression and windproof is the best; when the windproof net is in “L” shape, the dust suppression effect is the worst. Comparing the dust suppression effect of the windscreen under different dusting parameters, it is obtained that while optimizing the plane parameters, height and opening rate, the influence of moisture content on the dust suppression effect of the windscreen also needs to be considered. The results show that when the moisture content when the dust suppression rate reaches 8%, the dust suppression rate can reach more than 85%, and the dust suppression effect is greatly improved.

摘要

Economic development not only promotes social progress, but also makes the electric energy consumed by the production and operation of various industries continue to increase, putting forward high requirements for the capacity and production rate of coalfired thermal power plants. The increase in the capacity of coal-fired thermal power plants is bound to be accompanied by the expansion of scale and the increase in the output of polluting organisms, leading to the intensification of environmental pollution caused by coal-fired thermal power plants. In this regard, this paper emphasizes that coal-fired power plants must strengthen their own environmental protection efficiency, carry out targeted prevention and control of various pollutants generated in the production process, innovate and improve on the basis of previous environmental protection measures, and meet the two-way demand of society for environmental protection and energy at the same time, so that coal-fired power plants can achieve better development in the new economic situation.
