Research and Application of the Extensive Resistivity and Efficient Electrostatic Precipitator

摘要

As the improving standard of environment protection, it is a flinty challenge to the Electrostatic Precipitator (ESP). The problems of the current ESP for treating high or low resistivity dust, minuteness dust and high concentration dust doesn't be resolved until now. So it has great significance to develop the economical ESP with high efficiency which can be used all kinds of situation. Sinosteel Tiancheng Environmental Protection Science & Technology Co., Ltd. has researched and used the extensive resistivity ESP in recent years. The new ESP's frame of cathode is appended assistant electrode, anode (grounding electrode) is interlaced collocation at the perpendicular way of airflow, the face of grounding electrode is parallel to airflow, which to form the combined type of adjustable single-double area ESP. It mainly aimed to treat with the problems of the current ESP for treating high or low resistivity dust, minuteness dust and high concentration dust, gives a new electric field's structure of ESP independently. In this article the technical solving way and dust collection improved mechanism of the extensive resistivity ESP were introduced emphatically. Secondly, in this article briefly introduced the result of medium industrial experiment research when the new ESP were used in power plant of Xiangfan city, Hubei province, China, and the industrial application effect of the new ESP for retrofitting 2×108 m2 ESP of the head of sinter band in sintering plant of Liu Zhou, China iron and steel company.
