Description

technical field

The invention relates to the field of environmental protection dust removal, in particular to an electrostatic dust removal device for pressurized cycle adsorption.

Background technique

With the rapid development of my country's economy and the acceleration of industrialization, the problem of environmental pollution in my country has become more and more serious. Especially in recent years, the frequent occurrence of haze weather in our country has caused the air pollution situation in our country to be very serious. Smoke and dust enter the atmosphere. Therefore, my country has restricted the smoke to be discharged into the atmosphere only after dust removal reaches the standard.

The dust collector can effectively reduce the dust in the flue gas. The dust collector is widely used in the factory. The factory produces a large amount of flue gas during the production process, especially in enterprises with high pollution industries such as power plants. The dust content in the flue gas is relatively high. High, the flue gas discharged into the environment will cause serious air pollution, and the flue gas needs to be effectively treated before it can be discharged. Dust collectors are an indispensable pollution control facility. Currently, the most widely used dust collectors are bag dust collectors. Filter, pulse dust collector, bag filter, cyclone dust collector, electrostatic precipitator and wet dust collector, etc., the dust content in the flue gas after dust removal is small, and the flue gas is discharged into the atmosphere without causing air pollution, which is welcomed by people.

At present, the electrostatic precipitator has high dust removal efficiency and wide application range, and is widely used by people. However, when the concentration of smoke and dust in the flue gas is high during the production process of the enterprise, it is difficult for the electrostatic precipitator to remove the smoke and dust in the flue gas through a single electrostatic adsorption. If it is completely removed, it is difficult to achieve the ideal dust removal effect, and the existing electrostatic precipitator has adsorption dead angles during the dust removal process, and it is difficult for the electrostatic plate to fully absorb the smoke and dust in the flue gas, which greatly reduces the dust removal effect of the flue gas.
