1 前言铁矿石烧结过程中要产生大量废气。从前,烧结废气均采用机械方法除尘,主要目的是保护风机而不是保护环境。1960年,第一套干式电除尘器在德国一家烧结厂投入使用。后来,在欧洲、日本等国家,几乎所有烧结厂都采用了电除尘器。电除尘的效率虽然高于机械除尘,但仍然达不到环境保护标准的要求。 1 Introduction Iron ore sintering process to produce a lot of exhaust. In the past, the sintering exhaust gas was mechanically dedusted, the main purpose is to protect the fan rather than the environment. In 1960, the first dry electrostatic precipitator was put into operation at a sintering plant in Germany. Later, in Europe, Japan and other countries, almost all sintering plants have adopted electrostatic precipitator. Although the efficiency of ESP is higher than mechanical dust removal, it still can not meet the requirements of environmental protection standards.
