Electrostatic precipitator is a kind of gas dedusting method, which relies on positive and negative ions to neutralize the ions on the dust. Electrostatic precipitator is a necessary supporting equipment for thermal power plants. It is an important environmental protection equipment to improve environmental pollution and air quality. Electrostatic precipitator is a kind of gas dedusting method, which relies on positive and negative ions to neutralize the ions on the dust. Electrostatic precipitator is a necessary supporting equipment for thermal power plants. It is an important environmental protection equipment to improve environmental pollution and air quality. In recent years, the technical level of electrostatic precipitator in China has made great progress, and electrostatic precipitator has been applied on a large scale.

Analysts pointed out that the function of electrostatic precipitator is to remove the particulate smoke and dust in the flue gas discharged from combustion stove or oil-fired boiler, so as to greatly reduce the amount of smoke and dust discharged into the atmosphere. With the development of society, air pollution is becoming more and more serious, human awareness of environmental protection is increasing, the requirements for air quality are higher and higher, and the market of electrostatic precipitator is becoming larger and larger.

After years of development and application, electrostatic precipitator has mature technology and high dust removal efficiency. At present, it has been widely used in electric power, metallurgy, chemical industry and other industries. Among them, the power system is still a large user, accounting for about 72% ~ 75% of the market share As a big country of electrostatic precipitator, China has entered the international advanced ranks not only in quantity but also in technical level. Electrostatic precipitator technology from the equipment body to the computer-controlled high and low voltage power supply, as well as insulation accessories, rapping devices, polar plates and polar wires, has all been localized, and some products have been exported to more than 30 countries and regions.

At the same time, China's electrostatic precipitator industry is developing in a more rational and healthy direction. The low-level competition situation has eased, and the previous vicious competition phenomenon has eased. The market price is stable and rising, which is more reasonable than that in previous years. Under the good industry background, many enterprises in China have begun to pay attention to new technology hotspots. They have made some progress in new technologies such as pan specific resistance electrostatic precipitator technology, mobile electrode electrostatic precipitator technology, thin film electrostatic precipitator technology and laminar electrocoagulation technology, which further promoted the atmosphere of industry innovation. Once there is a breakthrough in the research of dust removal theory, it will bring a qualitative leap to the development of electrostatic precipitator industry.

At present, many large and medium-sized environmental protection industries in China have increased their investment in the technical research and development of electrostatic precipitator, which has made great progress in the application of electrostatic precipitator. China's electrostatic precipitators have entered the international advanced ranks not only in quantity, but also in technical level.
