With the acceleration of industrialization and urbanization, China's worsening air pollution, increasingly stringent emission standards of air pollutants, high removal efficiency of bag filter, electrostatic precipitators have been widely used. Currently, electrostatic precipitators and baghouse dust is the mainstream technology. About electrostatic precipitator and baghouse dust are two ways of comparison as follows: compared with electrostatic precipitators bag filter has a greater advantage in terms of energy conservation, under the national emission standards are becoming increasingly stringent conditions, the use of the bag ESP will be the main selection control dust pollution.
