干式捕塵器设备简单造价便宜,尤其在极度缺水的情况下更有其应用的价值,如若运用得好,它可以免去像湿式凿岩所存在的对微小粉塵控制不住的缺点。目前由于干式捕塵器在设计上尚存在一定的问题,致使目前没有大量的推广使用。我俩曾对干式作业用捕塵器除塵进行了如下的试验调查.一、情况的简介:××地独头掘进坑道,凿岩机是仿苏 OM-506中型,鑽头是硬质合金品,风压机的送风压力在4-5公斤/平方米。岩石绝大多数为花岗岩类,石质坚硬系数在6-7,含游离二氧化矽皆在40%以上。二、二种捕塵器的效果考核:二种捕塵器,一种是仿造苏联的乌斯波恩5型
Simple and cheap dry-cleaning equipment, especially in the case of extreme water shortage more application value, if well used, it can be removed like wet rock drilling there is no control of the shortcomings of small dust. Currently, there are still some problems in the design of dry-type dust catchers, resulting in a large number of popularization and application. We have carried out the following experimental investigations on dust removal for dry-running dust collector: I. Introduction to the situation: × × excavation of tunnels by themselves, rock drills are imitation of the Soviet Union OM-506 medium-sized, the drill bit is cemented carbide products, Air pressure of the air supply in the 4-5 kg / square meter. The vast majority of rock granite class, rock hard coefficient in the 6-7, containing more than 40% of free silica. Second, the effect of two kinds of dust catcher assessment: two kinds of dust catcher, a copy of the Soviet Union’s Uestorn 5
