Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to the structure of a cleaning device installed inside a cabinet in an electrostatic precipitator.

(Prior Art) FIG. 2 shows a side sectional view of an electrostatic precipitator equipped with a conventional cleaning device. A cabinet 2 is mounted on a base 1 and has an entrance door 3 and an exit door 4. A plurality of dust collection units 3 are housed inside the cabinet 2. On the outflow side of the dust collection unit 3, a plurality of plate blow pipes 6 are provided which swing vertically in the direction indicated by the arrow P. A plurality of electrode plate blowing nozzles 7 are attached to each electrode plate blowing pipe 6.

(Problems to be solved by the invention) The cleaning device with the above structure can only clean the dust collector electrode plate and the insulator, and the disadvantage is that dust accumulates on the outlet door 4 and the lower part of the outlet side of the cabinet 2. It was hot.

In view of the above-mentioned circumstances, the purpose of this invention is to further provide a nozzle capable of cleaning the outflow side (back side) and the lower part of the outflow side inside the cabinet, and to improve the cleaning device to prevent dust from accumulating.

(Means for solving the problem) In order to achieve the above-mentioned purpose, this invention places a rear blow nozzle at a symmetrical position to the front plate blow nozzle attached to the rear side of the conventional plate blow pipe. Established.

(Function) In addition to cleaning the rear exit door surface inside the cabinet by providing the rear blow nozzle as described above, this rear blow nozzle has a wider swing range than the vertical swing range of the electrode plate blow piping, so it cleans the inside of the cabinet on the outflow side. The ceiling and bottom of the machine can also be cleaned.

(Embodiment) FIG. 1 is a side sectional view of an electrostatic precipitator showing an embodiment of this invention, and the same parts as in FIG. The nozzle newly provided with this invention is the rear blow nozzle 8, which is mounted on the rear side of the plate blow pipe 6, symmetrically with the plate blow nozzle 7, which has conventionally been attached on the front side. Therefore, the range of vertical movement is wider than that of the plate blow pipe, so it is possible to clean not only the exit door surface but also the ceiling surface and bottom surface on the outflow side of the cabinet.

(Effects of the invention) In this invention, in addition to the conventional plate blow nozzle installed on the front side of the plate blow piping, a rear blow nozzle was also installed on the rear side, so the exit door surface, which could not be cleaned conventionally, was installed. , the ceiling surface, and the bottom surface can also be cleaned, making it possible to keep the entire surface of the outflow side inside the cabinet and the electrode plate clean.
