Technical Field

[0001] The utility model relates to a cleaning device, in particular to an electrostatic dust collector cleaning device, and belongs to the technical field of mechanical design and manufacturing. Background Art

[0002] The electrostatic precipitator is one of the more commonly used dust removal equipment in industrial production. It uses the static electricity emitted by the electrodes arranged on the central axis of each dust removal pipe arranged in a matrix to adsorb the dust in the gas flowing through the dust removal pipe onto the wall of the dust removal pipe, thereby removing the dust in the gas. After the electrostatic precipitator in actual production has been used for a period of time, the dust attached to the dust removal pipe and the electrode needs to be cleaned, otherwise it will affect the normal use of the electrostatic precipitator, and even cause faults such as short circuit in severe cases. The existing cleaning method is to set a spray head above several dust removal pipes arranged in a matrix, and use the sprayed water to rinse the dust removal pipes and electrodes below. In the actual cleaning process, it is found that the water sprayed on the top can effectively rinse the top, but it cannot effectively rinse each dust removal pipe. It can only clean some dust removal pipes facing the water spray. There are cleaning dead corners where multiple dust removal pipes cannot be cleaned, which in turn affects the normal use of the electrostatic precipitator. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0005] The spraying member is configured as a nozzle with a rear end connected to the side wall of the spraying pipe, a front end passing through a corresponding through hole on the side wall of the dust removal pipe, and an inclined downward in the dust removal pipe. The front end of the nozzle is an open end. The nozzles are arranged on the left and / or right side walls of the spraying pipe, and the number and positions of the nozzles are adapted to the number and positions of the dust removal pipes, so that the inner walls on both sides of the dust removal pipe can be cross-sprayed through the oppositely arranged nozzles, and the electrode rod in the center can also be sprayed at the same time, so as to thoroughly clean the dust on the dust removal pipe and the electrode rod and eliminate cleaning dead corners.

[0006] The multiple spray pipes distributed longitudinally or transversely are configured as horizontal square tubes or circular tubes, the connecting tubes connected to both ends of the multiple spray pipes are correspondingly configured as horizontal square tubes or circular tubes, and a dust removal pipe is provided between every two spray pipes, so that the inner wall of the dust removal pipe can be cross-sprayed from both sides through a row of spray pipes on both sides of the dust removal pipe.

[0007] The utility model has the following advantages and effects: by adopting the above scheme, water is supplied to multiple spray pipes through a connecting pipe, and then a plurality of spray members arranged opposite to each other on the multiple spray pipes are used to cross-spray both sides of the corresponding dust removal pipes at the same time, which can not only thoroughly clean the inner wall of each dust removal pipe, but also clean the electrode at the center of the dust removal pipe. While ensuring high efficiency and speed and eliminating dead corners in cleaning, it also ensures the cleanliness after cleaning, providing guarantee for the normal use of the subsequent electrostatic precipitator.
