高炉煤气布袋除尘具有节能、节水、改善操作环境和节约资金等优点,已为我国生产实践所证实。近几年来国外将其成功地用于大型高炉,提高了炉顶余压发电能力,收到良好的节能效果。所以干式除尘已成为发展方向。干式除尘方法很多,布袋除尘是首先试验并广泛使用的一种。它结构简单,运行稳定,除尘效果好,今后将有更大发展。其它如干式电除尘、颗粒层除尘等正在试验,今后可能取得实质性进展,构成多种干式除尘方法。以布袋除尘净化高炉煤气我国起步较早,推广得也快,十几年来全国至少有三四百座小高炉采用,炉容也扩展到300m~3高炉。由于技术原因,未能及时用到大高炉上来。
Blast furnace gas bag dust with energy saving, water saving, improve the operating environment and save money, etc., has been confirmed for the practice of our production. In recent years, foreign countries have successfully used the same for large blast furnaces, enhanced the residual pressure power generation capacity of the roof and received good energy-saving effects. So dry dust has become the development direction. Dry dust removal methods are many, bag dust is the first test and a widely used. Its structure is simple, stable operation, dust removal effect is good, there will be more development in the future. Others such as dry electrostatic dust removal, particle dust removal and other tests are being conducted in the future may make substantial progress, constitute a variety of dry dust removal methods. In order to purify the blast furnace gas with bag dust, our country started earlier and got more promotion. At least three or four hundred small blast furnaces were used throughout the country over the past decade, and the furnace capacity was also extended to 300-3 blast furnaces. Due to technical reasons, failed to use the blast furnace up.
