Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic precipitators, and particularly to an electrostatic precipitator with a fine screening function. Background Art

[0002] Electrostatic precipitators are essential auxiliary equipment in thermal power plants. Their function is to remove particulate soot in the flue gas discharged from coal-fired or oil-fired boilers, thereby significantly reducing the amount of soot discharged into the atmosphere. This is an important environmental protection device for improving environmental pollution and air quality. Electrostatic precipitators use the electric field force of a high-voltage direct current electric field to separate dust particles suspended in the gas. However, there are still certain deficiencies in existing electrostatic precipitators, that is, no auxiliary dust removal mechanism is provided at the air inlet end of the electrostatic precipitator, which can preliminarily screen and remove larger particles in the gas so that they do not enter the interior of the working chamber of the electrostatic precipitator. On the one hand, it can reduce the working intensity of the electrostatic precipitator and its working pressure, and on the other hand, it can further improve the working efficiency of the electrostatic precipitator.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, and has the following advantages:

[0016] 1. A filtering load-bearing plate is fixedly installed in the air inlet pipe of the electrostatic precipitator. The first filter plate and the second filter plate are arranged on the filtering load-bearing plate to preliminarily filter the gas entering the electrostatic precipitator, so that larger particles in the gas will not enter the electrostatic precipitator.

[0017] 2. After the gas enters the intake pipe, it will push the plug-in mating plate to move. As the plug-in mating plate moves, under the action of the first driving connecting rod, it will drive the two first dust removal strips to move towards both sides of the first filter plate, facilitating the removal of impurities on the first filter plate. At the same time, as the plug-in mating plate moves, it will also drive the connecting movable frame to move upward. Then, under the action of the connecting movable frame, it will drive the closing hinge plate to rotate upward, preventing the dust and impurities collected in the dust collection box from entering the intake pipe through the first dust falling hole during the intake process.

[0018] 3. In addition, during the upward movement of the connecting movable frame, it will drive the movable hole closing plate to move, preventing the dust and impurities in the dust collection box from entering the intake pipe through the second dust falling hole during the intake process. At the same time, as the movable hole closing plate moves, it will also drive the second dust removal strip to move towards both sides of the second filter plate. That is, during the intake process, the first dust removal strip and the second dust removal strip are respectively on both sides of the first filter plate and the second filter plate. In this way, when the intake stops, the first dust removal strip and the second dust removal strip are reset, and at the same time, the first dust falling hole and the second dust falling hole are opened. 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 collection box respectively, ensuring the long-term use of the first filter plate and the second filter plate.

Also, since the closing hinge plate 6 and the movable hole closing plate 7 are reset, the first dust falling hole 27 and the second dust falling hole 29 are in an open state, and the dust and impurities can fall into the dust collection box 18. When the dust collection box 18 needs to be cleaned, just lift the safety lock plate 16 upward and remove it.
