石家庄市煤炭批发部煤场,81年经营40万吨,储煤10万吨,旺季吞吐量日达2000吨。4月份试制煤场喷水除尘设备。在一般天气条件下,早晨、中午喷水两次,不但解决空气污染,防止煤肺病;同时,可降低煤炭损耗。工艺原理:机井水经潜水泵抽入蓄水池,再经离心清水泵加压,输入地下管道,最后经可自 Coal yard of Shijiazhuang Coal Wholesale Department handled 400,000 tons of coal and 100,000 tons of coal in the year of 81. The peak season throughput reached 2,000 tons. In April, coal-fired water dedusting equipment was trial-produced. Under normal weather conditions, spraying water twice in the morning and at noon will not only solve air pollution and prevent coal-pulmonary disease, but also reduce coal loss. Process principle: The well water is pumped into the reservoir via a submersible pump, and then pumped by a centrifugal clear water pump to enter the underground pipeline.
