Description

Technical Field

[0001] The present invention relates to the technical field of off-line dust cleaning of anode plates and cathode lines of electrostatic precipitators, and more specifically, to a remote control dust cleaning device and method for electrostatic precipitators. Background Art

[0002] Electrostatic precipitator is a dry dust collection device that uses the high voltage discharge of the cathode line to generate a large number of positively and negatively charged particles. When the dusty flue gas flows between the anode plate and the cathode line, the dust particles are adsorbed by the positively and negatively charged particles. The positively charged particles adsorb the dust and move toward the cathode line and are adsorbed on the cathode line. The negatively charged particles adsorb the dust and move toward the anode plate and are adsorbed on the anode plate.

[0003] In order to ensure the normal discharge and continuous and efficient operation of the electrostatic precipitator, it is necessary to remove the dust attached to the anode plate and cathode wire through mechanical vibration, ultrasonic impact and other methods.

[0004] For manufacturing and economic considerations, most electrostatic precipitators use carbon steel for their anode plates and cathode wires. As the equipment runs longer, the surfaces of the anode plates and cathode wires become rough due to dust erosion or corrosion, and their ability to adhere to dust becomes stronger.

[0005] After the electrostatic precipitator has been working continuously for a long time, the anode plates and cathode wires are too thickly coated with dust and ash to be processed online, so it is necessary to use the downtime opportunity for offline cleaning. The currently known electrostatic precipitator cleaning technology has great limitations, and usually only considers the cleaning of the anode plates. Existing electrostatic precipitator cleaning technology usually requires changes to the structure of the precipitator or the material of the precipitator, and is only designed for cleaning the anode plates, without considering the cleaning of the cathode wires, which are the key components of the electrostatic precipitator. In addition, the existing known technology requires changes to the structure or material of the electrostatic precipitator, which is difficult and costly to modify, and is difficult to apply in actual production work. Summary of the invention

[0006] Based on this, the object of the present invention is to provide a remote control electrostatic precipitator cleaning device and method, which can realize remote control cleaning of anode plates and cathode wires without changing the structure and materials of the electrostatic precipitator itself.

The frame can be adjusted according to the main size of the anode plate to ensure that the frame and the anode plate are well matched.

[0009] In the present invention, the device relies on the anode plate itself as a moving track. After the cleaning device is installed on the anode plate, the device can be remotely operated outside the electrostatic precipitator to clean the cathode line while cleaning the anode plate.

The device has low manufacturing and use costs, can replace manual off-line cleaning of the electrostatic precipitator, has high cleaning efficiency, and good cleaning effect.

A spring is provided in the vertical direction between the cleaning scraper and the anode plate to ensure close contact between the cleaning scraper and the anode plate during the working process, enhance the scraping ability and control the descending speed of the cleaning device.

[0015] The invention has strong applicability, does not need to change the structure and material of the original electrostatic precipitator, relies on the original electrostatic precipitator anode plate as a moving track, and realizes the cleaning of the anode plate and the cathode line.

[0032] like Figure 1-3 As shown, a remote control type electric dust collector cleaning device, which includes an electric drive and wireless control component 1, a drive shaft 2, an anode plate 10, a cathode wire 8, and a detachable frame 5;

[0033] The electric drive and wireless control component 1 is connected to the drive shaft 2, the drive shaft 2 is connected to the detachable frame 5, the detachable frame 5 is adapted to the size of the anode plate 10, and after the detachable frame 5 completes the cleaning of the anode plate 10 and the cathode line 8 on one side, it can be removed and installed on another anode plate 10 to continue cleaning.

[0034] Specifically, the electric drive and wireless control component 1 and the drive shaft 2 are both arranged on one side of the detachable frame 5. The upper frame and the lower frame of the detachable frame 5. The electric drive and wireless control component 1 can remotely control the dust removal and realize the upward, downward and stop functions of the dust removal device.

[0035] The detachable frame 5 is a metal material with rigidity. The frame is a detachable structure, and the dust cleaning device is installed on the anode plate 10 and the preload force between the roller and the anode plate is adjusted through the detachable frame.

[0036] Specifically, in this embodiment, friction wheels 3 and guide wheels 6 are provided on both sides of the upper frame, the upper frame is connected to the drive shaft 2, and a dust cleaning cylinder brush 4 is arranged on the drive shaft 2.

[0037] In this embodiment, the cleaning cylinder brush 4 is arranged on the upper frame driving shaft 2, and the cleaning device realizes the cleaning effect on the cathode line 8 and the anode plate 10 during the up and down movement. Two cleaning scrapers 7 are arranged on the two non-driving frames of the lower frame of the cleaning device, and the cleaning device realizes the scraping cleaning effect on the anode plate 10 during the up and down movement. A cleaning plate brush 9 is also arranged on the lower half of the cleaning device to realize the cleaning effect on the cathode line 8.

[0038] Through this device, when the electrostatic precipitator is stopped, the anode plate 10 and the cathode line 8 can be remotely cleaned. This device does not need to change the structure of the electrostatic precipitator itself, and uses the existing electrostatic precipitator anode plate itself as a moving track. The dust cleaning device is simple to install. The dust cleaning device can move up and down along the anode plate 10, and the dust scale attached to the cathode line and the anode plate is removed by the rotation of the dust cleaning brush 4 and the scraping action of the dust cleaning scraper 7.

[0046] S4. During the upward and downward movement of the cleaning device, the cleaning scraper 7 scrapes the anode plate 10 to clean the surface dust;

[0047] S5. After the anode plate 10 and cathode line 8 on one side are cleaned, the cleaning device is disassembled and installed on another anode plate 10 to continue the cleaning work or multiple cleaning devices are set up at the same time to perform the cleaning work.

[0048] Through this device, when the electrostatic precipitator is stopped, the anode plate 10 and the cathode line 8 can be remotely cleaned outside the precipitator. This device can replace manual cleaning work, and can effectively solve the problems of low manual cleaning efficiency and dust harming health caused by limited space, high-altitude work, and poor working environment. This device does not need to change the structural composition of the electrostatic precipitator itself, and uses the existing electrostatic precipitator anode plate itself as the movement track. The installation method of the cleaning device is simple. The cleaning device can move up and down along the anode plate 10, and the ash attached to the cathode line 8 and the anode plate 10 is removed by the rotation of the cleaning cylinder brush 4, the scraping action of the cleaning plate brush 9 and the cleaning scraper 7.
