Why the Coal-fired Power Plant should change the Electric bag to bag house filter bags?
Mar 14, 2018

Electrostatic precipitator is the main power plant in China. The application of electrostatic precipitator in China is earlier than before. Due to the failure of filter material manufacturing process, the filter bag was damaged; resulting in low efficiency of dust removal and frequent bag change, resulting in the bag filter was not widely applied.

In recent years, with the development of the manufacturing technology of filter material, bag filter in the filter strength, high temperature resistance, corrosion resistance, abrasion resistance and other aspects have greatly improved. 15~50mg/m can be controlled by the concentration of dust emission fand dust collector, has been widely used in power plants, metallurgy, chemical, cement and other industries. Because the country is increasingly high demands on the soot emission standards, the existing electrostatic precipitator, to meet the new emission standards must be carried out technological transformation.

The advantages of filter bag Precipitator compared with Electrostatic Precipitator

The increased ventilation can be handled; the filter medium can be changed when the process condition is changed.

When used in the dry desulfurization system, the desulfurization efficiency can be improved properly, the broken filter elements can be replaced at any time, and the high efficiency operation can be ensured for a long time.

Bag dust collector can be designed into several independent units to realize online maintenance and maintenance.

The dust removal efficiency is high, the dust above 0.3 nm can be captured, and the dust containing gas purifying knife is made up of 15 mg / m or less. The structure is relatively simple, the operation and maintenance are convenient, and the cost and operation cost are far lower than that of the electric precipitator.

Reduced maintenance, online maintenance; no more precise restrictions on changes in the properties of inlet dust
