technical field

The utility model relates to the technical field of flue gas dedusting devices, in particular to an electric bag composite deduster.

Background technique

Electrostatic bag composite dust collector is a new type of energy-saving and high-efficiency dust collector that organically integrates two dust removal mechanisms of electrostatic dust removal and filter dust removal. In the dust collector, the pre-stage electrostatic precipitator uses the ionization of the gas under the high-voltage electric field, and the dust obtains ions to be charged, and moves to the electrode with the opposite polarity under the action of the electric field force, thereby being trapped. Due to the good conditioning of the flue gas (temperature, pressure, humidity and other factors), the pre-stage electrostatic precipitator can effectively remove more than 80% of the dust. Coupled with the advantages of electrostatic precipitator in the running resistance of various precipitators, the electric bag composite precipitator is complementary in technology. First, the electric precipitator is set in the front, which can capture a large amount of dust and settle the unextinguished dust in the high-temperature flue gas. "Red Star" particles buffer the uniform airflow, and the bag filter is connected in series to collect a small amount of fine dust and strictly control the discharge. At the same time, when any of the two dust collection areas fails, the other area still maintains a certain dust collection effect. , have a strong mutual complementarity.

If the temperature of the flue gas entering the device is too high, the flue gas will have a strong erosive effect on the interior, which will reduce the service life of the internal parts and increase the cost of flue gas treatment.
