Description
Technical Field
The invention belongs to the technical field of dust removal, and particularly relates to a novel composite plate type electrostatic dust collector.
Background
The atmosphere is a natural environment in which humans live, but with the continuous development of industry, air fine-particle pollutants represented by PM2.5 are increasing. The electrostatic dust collector is dust collecting equipment widely applied to thermal power enterprises, and can collect dust particles with the size of more than 0.01 microns, however, the electrode wire and the dust collecting plate have higher maintenance cost in the later period, so that how to reduce the loss of the electrode wire and the dust collecting plate as much as possible on the premise of meeting the national smoke emission standard is a problem which is worth focusing on by a plurality of enterprises.
Disclosure of Invention
The invention provides a technical scheme, which is mainly used for reducing the use of electrode wires and dust collecting plates as much as possible on the premise of meeting the national smoke emission standard.
In order to solve the problems, the technical scheme provided by the invention is as follows: a novel composite plate-type electrostatic precipitator comprises a flue gas inlet, a valve, a dust chamber and a smoke exhaust pipe. Wherein the dust removing chamber comprises a filter screen, an electrode wire, a dust collecting plate and an ash storage hopper. The flue gas air inlet is provided with a valve on the pipeline connected with the dust removal chamber, and the front end of the dust removal chamber is gradually expanded, so that the purpose of the process is to reduce the flow rate of flue gas, and the collection efficiency of dust particles is improved. The front part of the dust chamber is provided with a filter screen. The electrode wire is electrified with high-voltage negative electricity, and the dust collecting plates are positioned on two sides of the charging chamber and are grounded. Thus, after the flue gas enters through the flue gas inlet, dust particles with larger particle size in the flue gas are filtered by the filter screen, and the dust particles which are not collected by the filter screen are negatively charged under the action of the electrode wire and are then adsorbed by the dust collecting plate. Therefore, part of dust particles with larger particle size are filtered out through the filter screen, and the loss of the electrode wire and the dust collecting plate is greatly reduced. The filter screen and the dust collecting plate are respectively provided with a vibrator, the filter screen and the dust collecting plate are cleaned through high-frequency vibration, and dust particles after cleaning fall into the ash storage hopper. Finally, the purified flue gas is discharged from the dust removing chamber.

Detailed Description
Specific embodiments of the present invention are described below with reference to the accompanying drawings.
The invention provides a novel composite plate type electrostatic precipitator, and referring to fig. 1 and 2, fig. 1 is a flow chart of operation of the electrostatic precipitator provided by the invention, and fig. 2 is a structure chart of a dust chamber provided by the invention. The dust remover comprises a flue gas inlet 1, a valve 2 and a dust removing chamber 3, wherein the dust removing chamber 3 comprises a filter screen 4, a dust collecting plate 5, an electrode wire 6, an electrode wire 7, an electrode wire 8, a dust collecting plate 9 and a dust storage hopper 10. The flue gas dust collector is characterized in that a valve 2 is arranged on a pipeline connected with the flue gas air inlet 1 and the dust collection chamber 3, a filter screen 4 is arranged at the front part of the dust collection chamber 3, electrode wires 6, 7 and 8 are arranged inside the dust collection chamber 3, the three electrode wires are electrified to be negative with high voltage, and a dust collection plate 5 and a dust collection plate 9 are arranged on two sides of the dust collection chamber 3 and are grounded.
The flue gas enters into the pipeline through the flue gas air inlet 1, the flow rate of the flue gas can be controlled through the valve 2, the flue gas enters into the dust chamber 3, part of dust particles with larger particle sizes are filtered through the filter screen 4, and the dust particles which are not collected by the filter screen 4 are negatively charged under the action of the electrode wire 6, the electrode wire 7 and the electrode wire 8, so that the dust particles are adsorbed by the dust collecting plate 5 and the dust collecting plate 9. The filter screen and the dust collecting plate are respectively provided with a vibrator, the filter screen and the dust collecting plate are cleaned through high-frequency vibration, and cleaned particles fall into the ash storage hopper 10. Finally, the purified flue gas is discharged from the dust removing chamber. The maintenance cost of the filter screen in the later stage is far lower than that of the electrode wire and the dust collecting plate, part of dust particles with larger particle sizes are filtered by the smoke through the filter screen, and the dust particles with smaller particle sizes, which are not collected by the filter screen, are adsorbed by the dust collecting plate. Therefore, the purification efficiency of the dust remover to the flue gas can be ensured, and the loss of the electrode wire and the dust collecting plate can be reduced.
