Description

Technical Field

[0001] The utility model relates to the technical field of wet electrostatic precipitators, in particular to an anti-pollution insulation structure. Background Art

[0002] Desulfurization tower wet electrostatic precipitator is often used in sintering, ironmaking, steelmaking and other production processes. It can effectively purify flue gas, remove harmful substances in flue gas, and reduce environmental pollution. For example, desulfurization tower wet electrostatic precipitator is used when carbon anode is roasted. However, with long-term operation, the tar pitch in the roasting flue gas will slowly deposit on the outer wall of the insulating porcelain bottle, destroying the insulation and causing the wet electrostatic precipitator to discharge frequently. Not only does it pose installation risks, but it will also cause flue gas emissions to exceed the standard, increasing safety and environmental risks for production enterprises. Therefore, how to design an anti-pollution insulation structure is a technical problem that needs to be solved urgently in this field. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Referring to Figure 1-2 , an anti-pollution insulation structure includes an insulating porcelain bottle 1, an oil receiving tray 6 and an air collecting cylinder 4 with an open bottom. It is easy to understand that both the air collecting cylinder 4 and the oil receiving tray 6 are made of insulating materials. The insulating porcelain bottle 1 is fixed on the mounting bracket 3 through a pull rod 2. In this embodiment, the mounting bracket 3 includes an upper support plate 301 and a lower support plate 302, which are connected by a plurality of support rods 303. On this basis, the pull rod 2 is fixed to the upper support plate 301 through a nut.

[0018] The air collecting cylinder 4 is sleeved outside the insulating porcelain bottle 1 and fixedly connected to the mounting bracket 3. Specifically, the air collecting cylinder 4 is fixedly connected to the upper support plate 301, and the fixed connection method is not limited. For example, in this embodiment, it can be connected by bolts (not shown in the figure). In other embodiments, bonding or other methods can be used.

[0019] The air collecting cylinder 4 is connected to an air inlet pipe 5, and the air inlet pipe 5 is connected to a hot air blower (not shown in the figure). During use, hot air is conveyed into the air collecting cylinder 4 through the air inlet pipe 5 by the hot air blower, so that the tar is softened and falls off, avoiding a large amount of tar pitch deposition on the side wall of the insulating porcelain bottle 1, reducing the discharge phenomenon of the wet electrostatic precipitator, and ensuring the safe and environmentally friendly operation of the purification system.

[0020] In this embodiment, the air inlet pipe 5 is connected to the top of the side wall of the air collecting cylinder 4, which is convenient for the side walls in all directions to be blown, avoiding the direct downward air inlet direction, resulting in a poor hot air blowing effect on the part of the side wall of the insulating porcelain bottle 1 far from the air inlet.

[0021] The lower end of the insulating porcelain bottle 1 is located in the oil receiving tray 6. The provided oil receiving tray 6 can collect the tar flowing down from the side wall of the insulating porcelain bottle 1 to avoid secondary pollution. The oil receiving tray 6 is installed on the mounting bracket 3. Specifically, in this embodiment, the oil receiving tray 6 is in a ring structure and is provided with a ring-shaped oil receiving groove. The inner wall of the insulating porcelain bottle 1 abuts against the inner wall of the oil receiving groove close to the center line. There are three support plates 10 (of course, more support plates 10 can also be provided in other embodiments) for supporting the oil receiving tray 6 rotatably connected to the mounting bracket 3. Specifically, a rotating shaft is provided on the lower support plate 302, and the support plate 10 is sleeved on the rotating shaft, and the support plate 10 can rotate around the rotating shaft. It should be noted that according to the above settings, when removing the oil receiving tray 6, only need to rotate the support plate 10 to the side far from the oil receiving tray 6, and then the oil receiving tray 6 can be removed. That is, the above setting method of the oil receiving tray 6 makes the oil receiving tray 6 easy to disassemble and assemble, and is convenient for regularly cleaning the oil receiving tray 6.

[0022] Furthermore, a handle 11 is provided at a position deviating from the rotation center of the support plate 10. The form of the handle 11 is not limited, as long as it is convenient to hold and rotate the support plate 10. For example, in this embodiment, the handle 11 is designed as a column, and in other embodiments, it can be designed as a plate or other shapes.

[0023] In this embodiment, an annular sliding groove 601 is provided at the outer top of the oil receiving tray 6, and a slidable sphere 7 is embedded in the annular sliding groove 601. It is easy to understand that half of the sphere 7 is located in the annular sliding groove 601 to ensure that the sphere 7 will not fall off. A connecting column 701 is provided at the top of the sphere 7. A scraping plate 8 is provided in the oil receiving tray 6, and the scraping plate 8 is inserted through the connecting column 701. A limiting block 9 is connected to the top of the connecting column 701 through a fastener. It should be understood that the limiting block 9 only needs to limit the scraping plate 8 from falling off, and it is not easy to press the scraping plate 8 too tightly to avoid the scraping plate 8 from sliding smoothly.

[0024] It should be noted that the scraper 8 slides along the annular chute 601 following the sphere 7, scraping the tar to one place, which further facilitates cleaning without the need to find another cleaning tool. In practical applications, an oil leakage hole (not shown in the figure) can be provided at the bottom of the oil receiving pan 6, and during use, the oil leakage hole is blocked by a plug. Further, the cross-section of the connecting column 701 perpendicular to the axis has a polygonal structure, for example, a rectangular structure (of course, in other embodiments, it can also be other polygonal structures such as a hexagonal or triangular structure). With such a setting, it is avoided that the scraper 8 rotates relative to the connecting column 701, resulting in unsmooth sliding.

[0025] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
