开展高炉煤气干法除尘技术研究,是国家的重点科研项目。冶金部安全技术研究所、武汉钢铁设计研究院和武钢燃气厂联合试验组按总体试验规划,选用沸腾反吹清灰的颗粒层除尘器实验室第一阶段试验现已完成。今将其概况略述于下。1.试验条件及结果:入口含尘量10克/米~3,工况下过滤气速10～30米/分;采用三种不同粒径的砂子(0.63—1.25;0.63—0.9;0.9—1.25毫米);砂层厚分别为200—500、200—400、400—600毫米;过滤阻力小于600—700毫米水柱;过滤时间6—8分钟以上。除尘效率
Blast furnace gas dry dust removal technology research, is the state’s key scientific research projects. Metallurgical Institute of Safety Technology, Wuhan Iron and Steel Institute Iron and Steel Design Institute and Wugang Gas Plant Joint Test Group, according to the overall experimental plan, the use of boiling backwashing particle layer dust collector laboratory first phase of the test has been completed. The outline is now outlined below. 1. Test conditions and results: The inlet dust content of 10 g / m ~ 3, under the conditions of filtration speed of 10 to 30 m / min; using three different particle sizes of sand (0.63-1.25; 0.63-0.9; 0.9- 1.25 mm); sand thickness 200-500,200-400,400-600 mm respectively; filtration resistance is less than 600-700 mm water column; filtration time 6-8 minutes. Dust removal efficiency
