Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically a waste gas desulfurization and electrostatic dust removal device. Background Technology

[0002] Industrial waste gas refers to the general term for various gases containing pollutants generated during fuel combustion and production processes within a company's factory area; specifically, it refers to the waste gas generated by factories, workshops, etc. Currently, when treating waste gas, it is necessary to first remove the dust in the waste gas, which is generally done by electrostatic dust removal. The working principle of existing electrostatic dust removal equipment is that the gas is electrically separated when it passes through a high-voltage electrostatic field. After the dust particles combine with negative ions and become negatively charged, they tend to discharge and deposit on the anode surface.

[0003] When removing dust from exhaust gas using dust removal equipment, the accumulated dust inside the equipment needs to be cleaned periodically after the equipment has been working for a period of time to avoid excessive dust buildup affecting the performance. The dust removal process needs to be paused during cleaning.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides an electrostatic precipitator for desulfurization of waste gas, comprising a working box 1, a box cover 11 at the top of the working box 1, and a pair of guide pipes 12 connected to both ends of the working box 1; a pair of conductive plates 2 are disposed inside the working box 1, conductive cloth 21 is disposed on the surface of the conductive plates 2, and a drive roller 22 is disposed inside the conductive cloth 21, with the inner surface of the conductive cloth 21 and the surface of the drive roller 22 under pressure; a pair of output motors 23 are disposed at the top of the box cover 11 and above the drive roller 22; the output end of the output motor 23 extends into the working box 1 and is connected to the top of the drive roller 22;

[0033] The work box 1 is equipped with multiple partitions 4 inside, which, together with the conductive cloth 21, isolate the space between a pair of conductive cloths 21 inside the work box 1; a docking shaft is provided at one end of the partition 4 near the conductive cloth 21; there is a pressure between the docking shaft and the end of the conductive cloth 21; a scraper 3 is provided between the conductive cloth 21 and the inner wall of the work box 1; multiple material extraction pipes 10 are connected to the side of the work box 1; a material extraction pump is connected to the outside of the material extraction pipes 10.

[0034] When removing dust from exhaust gas using electrostatic precipitators, the accumulated dust needs to be cleaned periodically after the equipment has been operating for a period of time to prevent excessive dust buildup from affecting performance. Cleaning requires pausing the exhaust gas dust removal process. However, in actual dust removal operations, large quantities of exhaust gas often need to be processed, and processing time is very tight. Therefore, for large-volume exhaust gas processing, the efficiency of existing dust removal equipment needs further improvement. To solve the above problems, this embodiment of the invention includes a conductive cloth 21, a drive roller 22, and other structures. The specific usage process is as follows: During use, exhaust gas is introduced into the working box 1 through the guide pipe 12, and simultaneously, the conductive plate 2 is energized, causing the conductive cloth 21 in contact with the conductive plate 2 to become simultaneously energized. Dust in the exhaust gas inside the working box 1 is adsorbed onto the surface of the conductive cloth 21. The output motor 23 drives the drive roller 22 to rotate. The drive roller 22 drives the conductive cloth 21 to slide on the outside of the conductive plate 2 through friction. When the conductive cloth 21 rotates around the conductive plate 2, the partition plate 4, in conjunction with the docking shaft at the end, isolates the exhaust gas from the scraper 3. When the conductive cloth 21 rotates, the scraper 3 scrapes off the dust adsorbed on the surface of the conductive cloth 21, which accumulates on one side of the scraper 3 and is then extracted through the extraction pipe 10. This completes the automatic cleaning of the conductive cloth 21, enabling the exhaust gas dust removal to operate continuously without interrupting the operation. It also improves the efficiency of exhaust gas dust removal and is beneficial for the treatment of large quantities of exhaust gas. It should be noted that when the dust is scraped on the conductive cloth 21, it first gradually accumulates on the conductive cloth 21. When it accumulates to a certain extent, the accumulated dust falls downward under its own gravity and is then extracted by the extraction pipe 10.

[0035] A baffle 5 is provided on one side of the scraper 3. One end of the baffle 5 contacts the conductive cloth 21, and the other end contacts the inner wall of the working box 1. Multiple hydraulic cylinders 51 are provided on the outside of the working box 1. The output end of the hydraulic cylinder 51 passes through the interior of the blade working box 1 and is connected to the baffle 5. When dust is extracted through the extraction pipe 10, the output end of the hydraulic cylinder 51 drives the baffle 5 to move closer to the scraper 3. The baffle 5 drives the dust falling from the conductive cloth 21 to move towards the scraper 3, thereby reducing the volume of the space where the dust falls in cooperation with the conductive cloth 21 and the scraper 3. This facilitates the extraction of dust by the extraction pipe 10.

[0036] A plastic roller 50 is rotatably mounted on one end of the baffle 5 near the conductive cloth 21. When the conductive cloth 21 rotates, the plastic roller 50 is driven to roll synchronously, which will not affect the adhesion of dust on the surface of the conductive cloth 21. This prevents the dust on the surface of the conductive cloth 21 from being scraped off to the side away from the scraper 3 when the conductive cloth 21 rotates, so that it cannot be drawn out by the extraction tube 10.

[0037] like Figures 6 to 9As shown, a pressure roller 6 is provided inside the conductive cloth 21 and on one side of the drive roller 22. A reserved notch 110 is provided at the top of the box cover 11 and directly above the pressure roller 6. A connecting shaft 61 is rotatably provided at the top of the pressure roller 6. The top of the connecting shaft 61 extends through to the top of the reserved notch 110. A pair of cylinders 7 are provided at the top of the box cover 11. A pair of pistons 71 are slidably connected inside the cylinders 7. A guide rod 72 is provided at the end of the piston 71 facing the outlet of the cylinder 7. A connector is provided between the guide rod 72 and the top of the connecting shaft 61. In use, the cylinder 7 drives the piston 71 and the guide rod 72 through the internal air pressure. The guide rod 72 drives the pressure roller 6 at the bottom of the connecting shaft 61 to squeeze the conductive cloth 21 through the connector at its end, so that the conductive cloth 21 is taut, which helps to maintain a stable friction force between the drive roller 22 and the conductive cloth 21.

[0038] An inflation pipe 74 is connected to the side of the cylinder 7, and the space between the inflation pipe 74 and a pair of pistons 71 inside the cylinder 7 is connected to the top of the cylinder 7; a pressure relief valve 73 is connected to the top of the cylinder 7; the pressure relief valve 73 is connected to the space between the pair of pistons 71 inside the cylinder 7; an air pump is connected to the outside of the inflation pipe 74, and the inflation pipe 74 continuously inflates the cylinder 7 through the air pump. When the air pressure inside the cylinder 7 reaches a certain level, the pressure is released through the pressure relief valve 73; this ensures that the pressure inside the cylinder 7 remains constant, thereby ensuring that the conductive cloth 21 remains continuously and stably taut.

[0039] A sealing plate 8 is sleeved on the outside of the connecting shaft 61, and the sealing plate 8 seals the top of the reserved notch 110. During use, the sealing plate 8 continuously seals the reserved notch 110 and moves synchronously with the connecting shaft 61 to ensure that the working box 1 is sealed during exhaust gas dust removal.

[0040] The bottom end of the drive roller 22 is provided with a circular groove; the roller surface of the drive roller 22 is provided with multiple vent holes communicating with the circular groove; the bottom end of the working box 1 is equipped with a valve 9 whose input end extends into the interior, and the input end of the valve 9 is connected to the circular groove; when in use, the valve 9 is connected to an external air pump, which draws air from the inside of the circular groove through the valve 9, causing the vent holes to generate negative pressure, which is sealed when in contact with the conductive cloth 21, thereby causing the vent holes to adsorb the conductive cloth 21. As the drive roller 22 rotates, the vent holes can increase the driving force of the drive roller 22 on the conductive cloth 21, which is beneficial to the stable rotation of the conductive cloth 21.

[0041] The valve 9 has a first connecting plate 91 at its input end and a second connecting plate 92 at its top. The second connecting plate 92 is arc-shaped and its arc surface is attached to the inner wall of the circular groove to block the vent holes that are not in contact with the conductive cloth 21. This increases the negative pressure when the conductive cloth 21 comes into contact with the vent holes, thereby improving the driving effect of the drive roller 22 on the conductive cloth 21. It should be noted that the exhaust gas extracted by the valve 9 is dust-treated exhaust gas that can be further processed.

[0042] A rotating belt 93 is slidably provided on the surface of the second connecting plate 92; when the drive roller 22 rotates, the rotating belt 93 on the surface of the second connecting plate 92 is driven to rotate synchronously, so that the second connecting plate 92 does not produce sliding friction with the inner wall of the circular groove, thereby preventing the drive roller 22 from overheating and damaging the conductive cloth 21; the conductive cloth 21 is specifically an aluminum foil fiber composite cloth; it is not breathable during use and the dust on the surface can be easily scraped off by the scraper 3.
