First, the characteristics of the electric and bag dust collector

1. The characteristics of the electric dust catcher electrostatic precipitator is strong electric field in corona discharge make gas ionization, dust charged,

Under the effect of electric field force make the dust separated from the gas. Its features are:

Ontology w filter pressure loss small < 300 pa.

W high temperature resistant, ordinary steel can run under 350 ℃.

W the first electric dust removal efficiency is high, generally can reach 70-80%, especially

Coarse particle size and dust than moderate resistance, high dust removal efficiency, its

Yu electric field only collect dust content of 20-30% of soot.

W is more sensitive to the characteristic of dust, appropriate than the resistance of 1 x 104-5 x 1010 Ω cm,

Efficiency is easily affected by working conditions of flue gas factor and changing.

2. Also called filtering characteristics of bag filter bag filter type dust collector, it makes use of fiber knitting production

Bag filter element to capture dust in the gas solid particles, it features:

W high dust removal efficiency, stable export emissions, or less commonly 50 mg/Nm3.

W is not sensitive to the characteristics of dust emission concentration, not affected by dust resistivity.

W soot cleaning cycle, the service life of filter bag affected by flue gas dust concentration, dust concentration

The higher the degree, ash removal time and shorter service life of filter bag.

W big resistance during operation, the general is 1500-2000 pa, the high cost of operation.

W is not suitable for operation under high temperature, be in commonly 160 ~ 200 ℃.

Second, the working principle of electric multiple dust bag 1, electricity bags defined in the multiple dust bag is in the multiple dust comprehensive utilization and the organic combination of electrostatic precipitators and bag

Advantages of dust collector, first by the electric field to capture a lot of dust in flue gas, after again

A combined efficient remaining fine dust baghouse collecting dust catcher. The dust

Stability (50 mg/Nm3) or less, the characteristics of the performance.

2, work principle,

Based on the working principle of the electrostatic precipitator and cloth dust collector, the organic combination of both

Dust advantage: the level of electric field in the flue gas in advance before 70 - more than 80% of the amount of dust; After class

Cloth bag dust removal device interception to collect the remaining amount of the flue gas dust. Among them, the former level electricity

Field of dust removal effect and charged role for improving the electric properties of bag filter plays an important role.
