水膜除尘器是以捕滴器为核心设备,与文丘里洗涤器或斜棒式洗涤栅组合而成,被广泛用于我国中小型火力发电厂和工业锅炉房,以达到净化烟气、保护环境的目的.尤其是采用麻石为主要材料的水膜除尘器,更具有节省钢材、造价低、耐磨损等优点,呈现出良好的应用前景.但目前所使用的水膜除尘器存在着耗水量大,文丘里管喉部流速高,易磨损等问题. Water film filter is based on the dropper as the core equipment, combined with the Venturi scrubber or inclined bar washing grid, is widely used in small and medium-sized thermal power plants and industrial boiler room in China, in order to achieve the purification of flue gas, protection Environmental purposes.Especially the use of granite as the main material of the water film dust collector, but also has the advantages of saving steel, low cost, wear resistance, etc., showing a good application prospects.But currently used water film precipitator has a consumption Large amount of water, venturi throat flow rate, easy to wear and other issues.
