In haze weather, inhalable particles are the most major pollutant, i.e., PM 2.5. PM2.5 means particulate matter having a particle size of 2.5 or less. Compared with larger particulate matters, the PM2.5 has strong activity, small particle size, generally carries harmful and toxic substances (such as bacteria, viruses and the like), has long movement distance in the atmosphere and long retention time, and thus has larger influence on air quality and human health. Because of the small particle size of the fine particulate matter (PM 10, PM 2.5), it is difficult to remove. An effective solution is to change the particle size distribution of dust particles in the air by a charge-coagulation device, so that fine particles are adhered to large particles or the fine particles are adhered to each other to be coagulated into large particles, and the large particles can be separated and removed from the air more easily.

When passing through the electric field coagulation mechanism, the charged particles with different polarities move in opposite directions under the action of electric field force, and then can collide with each other and coagulate to form large particles.

The existing charge coagulation device has the following defects:

1) the charging mechanism and the coagulation mechanism operate independently, and gas needs to pass through the charging device and the coagulation device in sequence for charging and coagulation, so that the whole charging and coagulation device is large in size and occupies more space;
