Abstract

Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, specifically to an electrostatic treatment device for waste gas. Background Technology
[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life, especially from chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries. These plants emit strong odors, severely pollute the environment, and negatively impact human health. To treat waste gas, electrostatic precipitators are typically used. These devices utilize the principle of electrostatics to purify particulate matter and harmful substances in the waste gas.
[0003] For example, utility model application CN202321182876.3 discloses an electrostatic treatment device for waste gas. This utility model incorporates a servo motor, a lead screw, and a guide rod. The output of the servo motor drives the lead screw to rotate, causing a movable plate to move downwards and pull the guide rod into the filter holes of the filter screen, thus clearing the filter. The servo motor, lead screw, and guide rod ensure that the filter can be cleared without disassembling it, making filter treatment more convenient and the device easier to use. However, due to the movable plate, the waste gas encounters resistance and its flow rate slows down, thus affecting the waste gas treatment efficiency.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an electrostatic treatment device for waste gas. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrostatic treatment device for waste gas, comprising a treatment box and an electrostatic generator. A filter assembly is installed at the opening at the top of the treatment box, and the filter assembly includes a connecting box, an air inlet pipe, a support base, a cylinder, a rack, a gear, a drive shaft, a brush, and a filter screen. An air inlet pipe is provided through the top right side of the connecting box, and a support base is fixed to the top left side of the connecting box. A cylinder is installed on the support base, and a rack is connected to the right end of the cylinder. A gear is connected to the outer wall of the rack, and a drive shaft passes through the middle of the gear. A brush is installed at the bottom end of the drive shaft. A filter screen is provided inside the connecting box, and the electrostatic generator is installed inside the upper part of the treatment box.
[0007] Furthermore, the interior of the processing box is fixed with a horizontal partition one and a horizontal partition two from top to bottom, and an air pump is installed on the bottom left side of the horizontal partition one.
[0008] Furthermore, the input end of the air pump is connected to an air inlet pipe two, and the top of the air inlet pipe two is provided with a trap cover, and the output end of the air pump is connected to a ventilation pipe one.
[0009] Furthermore, a servo motor is installed on the bottom right side of the horizontal partition, and the output end of the servo motor is connected to a drive shaft, with a synchronous pulley fitted around the drive shaft.
[0010] Furthermore, a second synchronous pulley is connected to the outside of the first synchronous pulley via a synchronous belt, and a second vent pipe is inserted through the middle of the second synchronous pulley. The second vent pipe is located inside the bearing at the opening in the middle of the horizontal partition plate.
[0011] Furthermore, the bottom end of the second vent pipe is connected to the third vent pipe, and an exhaust pipe is installed through the bottom of the third vent pipe.
[0012] Furthermore, the left side of the processing box is provided with a drain port, a filling port and an air outlet from top to top, and the air outlet passes through the opening on the top left side of the horizontal partition.
[0013] This utility model provides an electrostatic treatment device for waste gas, which has the following beneficial effects:
[0014] 1. This utility model uses a cylinder to drive a rack to reciprocate in the horizontal direction. The rack and gear mesh to transmit power and make the drive shaft rotate, so that the brush can clean the filter screen.

Detailed Implementation
[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figure 1 and Figure 2 As shown, an electrostatic treatment device for waste gas includes a treatment box 1 and an electrostatic generator 3. A filter assembly 2 is installed at the opening at the top of the treatment box 1. The filter assembly 2 includes a connecting box 201, an air inlet pipe 202, a support base 203, a cylinder 204, a rack 205, a gear 206, a drive shaft 207, a brush 208, and a filter screen 209. The air inlet pipe 202 is installed through the top right side of the connecting box 201, and the support base 203 is fixed to the top left side of the connecting box 201. The cylinder 204 is installed on the support base 203, and the right end of the cylinder 204 is connected to the rack 205. The outer wall of the rack 205 is connected to the gear 206, and the drive shaft 207 passes through the middle of the gear 206. The bottom end of the drive shaft 207 is installed with a brush 208. The filter screen 209 is installed inside the connecting box 201, and the electrostatic generator 3 is installed inside the upper part of the treatment box 1.
[0022] The specific operation is as follows: the cylinder 204 drives the rack 205 to reciprocate in the horizontal direction. The rack 205 and the gear 206 mesh to transmit power, causing the transmission shaft 207 to rotate, so that the brush 208 cleans the filter screen 209. Since the brush 208 is designed in a long strip shape, it reduces obstruction and avoids gas accumulation, while removing dust efficiently over a large area.
[0023] like Figure 1 and Figure 3As shown, inside the processing box 1, from top to bottom, are fixed horizontal partition 4 and horizontal partition 5. An air pump 6 is installed on the bottom left side of horizontal partition 4. The input end of the air pump 6 is connected to an air inlet pipe 7, and a trap hood 8 is installed on the top of the air inlet pipe 7. The output end of the air pump 6 is connected to a ventilation pipe 9. A servo motor 10 is installed on the bottom right side of horizontal partition 4, and the output end of the servo motor 10 is connected to a drive shaft 11. A synchronous pulley 12 is sleeved on the outside of the drive shaft 11. The outside of 12 is connected to a timing pulley 14 via a timing belt 13, and a vent pipe 15 is inserted through the middle of the timing pulley 14. The vent pipe 15 is located in the bearing at the opening in the middle of the horizontal partition 5. The bottom end of the vent pipe 15 is connected to a third vent pipe 16, and an exhaust pipe 17 is inserted through the bottom of the third vent pipe 16. The left side of the treatment box 1 is provided with a drain port 18, a filling port 19 and an exhaust pipe 20 from top to top, and the exhaust pipe 20 is inserted through the opening on the top left side of the horizontal partition 5.
[0024] The specific operation is as follows: Drive shaft 11 and synchronous pulley 12 rotate under the drive of servo motor 10. The synchronous belt 13 meshes with synchronous pulley 12 and synchronous pulley 14 to transmit power, causing ventilation pipe 15, ventilation pipe 16 and exhaust pipe 17 to rotate. This allows the waste gas to be uniformly introduced into the acid-base neutralizing agent. The stirring action of exhaust pipe 17 ensures that the waste gas and acid-base neutralizing agent are fully mixed, ensuring the purification effect and preventing secondary pollution.
[0025] In summary, when using the electrostatic treatment equipment for this waste gas, first connect the inlet pipe 202 to the waste gas pipe, then inject the acid-base neutralizing agent into the treatment tank 1 through the liquid filling port 19. After the waste gas enters the connecting box 201 through the inlet pipe 202, the filter screen 209 will filter the particulate matter in the waste gas. The treated waste gas will then reach the electrostatic generator 3 for electrostatic dust removal.
[0026] Next, the air pump 6 operates to introduce the waste gas into the acid-base neutralizing agent through the second air inlet pipe 7, the first air inlet pipe 9, the second air inlet pipe 15, the third air inlet pipe 16, and the exhaust pipe 17 in sequence. Since the end of the first air inlet pipe 9, which is away from the air pump 6, is located in the bearing at the inlet of the second air inlet pipe 15, the servo motor 10 drives the drive shaft 11 and the first synchronous pulley 12 to rotate. The synchronous belt 13 meshes with the first synchronous pulley 12 and the second synchronous pulley 14 to transmit power, causing the second air inlet pipe 15, the third air inlet pipe 16, and the exhaust pipe 17 to rotate. This can evenly distribute the waste gas in the acid-base neutralizing agent. Under the stirring action of the exhaust pipe 17, the waste gas will be fully mixed with the acid-base neutralizing agent to prevent secondary pollution. The purified gas is discharged from the exhaust pipe 20.
[0027] When the surface of filter screen 209 becomes clogged, the cylinder 204 on the support base 203 is activated. The cylinder 204 drives the rack 205 to reciprocate in the horizontal direction. The rack 205 and the gear 206 mesh to transmit power, causing the drive shaft 207 and the brush 208 to rotate. This allows the brush 208 to clean the surface of filter screen 209. Because the brush 208 is designed in a long strip shape, it reduces the resistance to airflow and reduces clogging.
[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
