[0002] Wet electrostatic precipitator is widely used in the power industry, mainly in coal-fired power plants, especially after wet desulfurization, to further remove dust, acid droplets, PM2.5 and other fine particles in the flue gas; it can effectively reduce the concentration of smoke emissions to even below 5mg / m 3 The emission standards meet strict environmental protection requirements; the flue gas after desulfurization contains a certain amount of sulfur dioxide, aerosols, PM2.5 and other substances, which will react with the oxygen and water in the spray water to generate impurities such as sulfates. These sulfates and impurities will be deposited inside the anode sheath to form dirt; such impurities are corrosive, so it is necessary to clean the dirt on the anode sheath regularly and effectively.

[0003] The anode sheath of the existing wet electrostatic precipitator is sprayed with water by a water spray component to form a water film on the surface of the anode sheath, so that the dust deposited on the dust collecting plate flows into the water storage tank with the water flow; the anode sheath of the wet electrostatic precipitator is a regular hexagonal anode tube. The anode sheath of the wet electrostatic precipitator will be scaled during long-term operation. Scaling seriously affects the dust removal effect, and problems such as high electric field flicker frequency and low voltage parameters will occur; after the unit is shut down, the scaling problem of the anode sheath is solved by manually replacing the severely scaled anode sheath or flushing the anode sheath with high-pressure water. However, at present, this type of solution has a large amount of labor, high labor cost and maintenance cost, long maintenance period, low maintenance economy, and cannot guarantee equipment reliability and personal safety.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a wet electrostatic precipitator anode sheath cleaning device, which can achieve the effect of removing deposited scale on the inner wall of the anode sheath through a scraper 102.

[0031] The cleaning assembly includes a flat plate 100 disposed on the end surface of the moving tube 107 and a scraper 102 disposed on the outer wall of the flat plate 100 for scraping off the scale; wherein,

[0032] When the operating rod 103 and the moving pipe 107 move relative to each other, the scraper 102 will move synchronously therewith to remove the scale.

[0033] The upper end of the moving tube 107 is fixed with a plate 100 , the operating rod 103 is slidably connected to the moving tube 107 , and one end of the scraper 102 is rotatably connected to the plate 100 .

[0034] A spring 101 is fixed on the surface of the scraper 102 , and the other end of the spring 101 opposite to the scraper 102 is fixedly connected to the plate 100 .

[0035] A pull wire 106 is connected to the surface of the scraper 102 , and the other end of the pull wire 106 opposite to the scraper 102 is connected to the operating rod 103 .

[0036] Pull the operating rod 103, the operating rod 103 moves downward relative to the moving tube 107, and the pull wire 106 connected to the surface of the operating rod 103 is pulled. The pull wire 106 pulls the scraper 102 to rotate relative to the flat plate 100, the scraper 102 is retracted, and the spring 101 is compressed, and the scraper 102 is placed into the inner wall of the anode sheath. Release the moving tube 107, the spring 101 extends, and the scraper 102 is squeezed against the inner wall of the anode sheath. Push the operating rod 103 downward, and the scraper 102 removes the deposited scale on the inner wall of the anode sheath.
