Description

A cleaning device for the anode sheath of a wet electrostatic precipitator Technical Field

[0001] This invention relates to the field of wet electrostatic precipitator technology, and in particular to a cleaning device for the anode sheath of a wet electrostatic precipitator. Background Technology

[0002] Wet electrostatic precipitators are widely used in the power industry, primarily in coal-fired power plants, especially after wet desulfurization, to further remove dust, acidic mist droplets, PM2.5, and other fine particulate matter from flue gas; they can effectively reduce flue gas emission concentrations to or even below 5 mg / m³. 3 The emission standards meet stringent environmental protection requirements. The flue gas after desulfurization contains a certain amount of sulfur dioxide, aerosols, PM2.5 and other substances. These substances react with oxygen and water in the spray water to generate impurities such as sulfates. These sulfates and impurities will deposit inside the anode sheath to form dirt. Such impurities are corrosive, so it is necessary to clean the anode sheath regularly and effectively.

[0003] Existing wet electrostatic precipitators (WESPs) use water spraying components to spray water onto the anode sleeve, forming a water film on its surface. This allows dust deposited on the collection plate to flow into the water storage tank. The anode sleeves of wet ESPs are hexagonal anode tubes. During long-term operation, scale buildup on the anode sleeves can occur, severely impacting dust removal efficiency and causing problems such as high electric field flicker and low voltage parameters. After the unit is shut down, the scale problem is addressed by manually replacing severely scaled anode sleeves or flushing them with high-pressure water. However, these solutions are currently labor-intensive, incurring high labor and maintenance costs, long maintenance periods, and low economic efficiency, and cannot guarantee equipment reliability and personnel safety. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wet electrostatic precipitator anode sheath cleaning device, comprising,

[0006] The adjustment assembly includes an operating lever and a movable tube movably disposed outside the operating lever; and,

[0007] The cleaning assembly includes a plate disposed on the end face of the moving tube and a scraper disposed on the outer wall of the plate for removing scale.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, referring to Figure 1, is the first embodiment of the present invention. This embodiment provides a wet electrostatic precipitator anode sleeve cleaning device, which can remove deposited scale from the inner wall of the anode sleeve by means of a scraper 102.

[0029] Specifically, a wet electrostatic precipitator anode sleeve cleaning device includes,

[0030] The adjustment assembly includes an operating lever 103 and a movable tube 107 movably disposed outside the operating lever 103; and,

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

[0032] When the operating lever 103 moves relative to the moving tube 107, the scraper 102 will move synchronously to remove the scale.

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

[0034] A spring 101 is fixed to the surface of the scraper 102, and the other end of the spring 101 relative 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 relative to the scraper 102 is connected to the operating lever 103.

[0036] Pulling the operating lever 103 causes it to move downward relative to the moving tube 107, pulling the pull wire 106 connected to the surface of the operating lever 103. The pull wire 106 pulls the scraper 102 to rotate relative to the plate 100. The scraper 102 retracts, compressing the spring 101 and placing the scraper 102 into the inner wall of the anode sleeve. Releasing the moving tube 107 causes the spring 101 to extend, pressing the scraper 102 against the inner wall of the anode sleeve. Pushing the operating lever 103 downward causes the scraper 102 to remove the deposited scale from the inner wall of the anode sleeve.

[0037] Example 2, referring to Figures 1-3, is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a sliding groove and a slider in the anode sheath cleaning device for wet electrostatic precipitators, which solves the problem of limiting the movement of the operating rod.

[0038] Specifically, the surface of the moving tube 107 is provided with a groove 104, and the upper end of the operating rod 103 is fixed with a slider 105, which is slidably connected to the groove 104.

[0039] When the operating lever 103 moves relative to the moving tube 107, the slider 105 slides inside the slide groove 104. The slide groove 104 restricts the movement position of the slider 105, ensuring the connection between the operating lever 103 and the moving tube 107. At the same time, it controls the angle of the scraper 102, ensuring that the scraper 102 can properly remove deposits while also ensuring the normal opening and closing of the scraper 102.

[0040] Example 3, referring to Figures 1-4, is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a pull wire movement path for the anode sheath cleaning device of the wet electrostatic precipitator, which solves the problem of normal transmission of the pull wire.

[0041] Specifically, the surface of the flat plate 100 is provided with a through groove, and the pull wire 106 is slidably connected to the through groove.

[0042] The surface of the moving tube 107 is provided with a groove, and the pull wire 106 is slidably connected to the groove.

[0043] The through groove on the surface of the flat plate 100 and the inclined groove on the surface of the moving tube 107 ensure the normal movement of the pull wire 106, so that the operating lever 103 can drive the scraper 102 to rotate when it moves, thus ensuring the stable transmission of the operating lever 103 and the scraper 102.

For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered.
