苏联《工业劳动安全》82年11期登载了有关采煤机采用挡板提高捕尘装置净化效果的试验,挡板目的在于限制尘源的通风速度减少空气含尘量。研究结果认为:采煤机采用挡板使喷雾降尘效果平均可提高30％,采用捕尘法时具有更大作用,因这种挡板可将全部含尘 The Soviet Union, “Industrial Labor Safety” 82, 11, published on the shearer baffle to improve the purification device dust catching effect test, the purpose of the baffle is to limit the ventilation rate of dust source to reduce the amount of dust in the air. The results show that: Shearer baffle spray dust reduction effect can be increased by an average of 30%, the use of dust catcher has a greater role, because this baffle can be all dust
