Description

Technical Field

[0002] The electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate smoke from the flue gas emitted by coal-fired or oil-fired boilers, thereby significantly reducing the amount of smoke discharged into the atmosphere. It is an important environmental protection equipment for improving environmental pollution and improving air quality. The electrostatic precipitator uses the electric field force of a high-voltage direct current electric field to separate dust particles suspended in the gas. However, the existing electrostatic precipitator still has certain shortcomings, that is, the air inlet end of the electrostatic precipitator is not provided with an auxiliary dust removal mechanism, that is, the larger particles in the gas can be preliminarily screened and removed so that they will not enter the working room of the electrostatic precipitator.

[0014] Compared with the prior art, the invention has the following advantages: 1. A filter carrier plate is fixedly installed in the air inlet pipe of the electrostatic precipitator. By arranging the first filter plate and the second filter plate on the filter carrier plate, the gas entering the electrostatic precipitator can be initially filtered, so that larger particles in the gas will not enter the electrostatic precipitator.

[0015] 2. After the gas enters the air inlet pipe, it will push the plug-in matching plate to move. With the movement of the plug-in matching plate, the two first dust removal strips will be driven to move to the two sides of the first filter plate under the action of the first driving connecting rod, so as to facilitate the removal of impurities on the first filter plate. At the same time, with the movement of the plug-in matching plate, the connecting movable frame will be driven to move upward, and then the closed hinge plate will be driven to rotate upward under the action of the connecting movable frame, so as to prevent the dust and impurities collected in the dust box from entering the air inlet pipe from the first dust collection hole during the air intake process.

[0016] 3. In addition, when the connecting movable frame moves upward, it will drive the movable sealing plate to move, so as to prevent dust and impurities in the dust collecting box from entering the air intake pipe from the second dust collecting hole during the air intake process. At the same time, with the movement of the movable sealing plate, it will also drive the second dust removal strip to move to both sides of the second filter plate, that is, during the air intake process, the first dust removal strip and the second dust removal strip are respectively located on both sides of the first filter plate and the second filter plate. In this way, when the air intake is stopped, the first dust removal strip and the second dust removal hole are opened at the same time. Under the action of the first dust removal strip and the second dust removal strip, the impurities accumulated on the first filter plate and the second filter plate can be scraped off and collected in the dust collecting box respectively, thereby ensuring the long-term use of the first filter plate and the second filter plate.
