Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, specifically to a backflush ceramic bottle box for an electrostatic precipitator. Background Technology

[0002] An electrostatic precipitator (ESP) is a primary cooling device for coke oven gas that uses a high-voltage direct current electric field to separate tar droplets from the gas. The ESP removes tar and dust from the flue gas after it has been washed and cooled in the conditioning tower before sending it to the next process. The washed and cooled flue gas enters the ESP through an inlet pipe, where it is captured by the electric field during its ascent, thus removing tar and dust. Finally, it is sent to the next process through an exhaust pipe connected to the exhaust port at the top of the ESP. ESPs are available in three structural forms: concentric circle, tubular, and honeycomb.

[0003] The existing technology has the following problems: At the top of the current electrostatic precipitator tank, there is a porcelain insulator box powered by an external power grid, containing porcelain insulators. During the operation of the electrostatic precipitator tank, a certain amount of moisture and dust often adheres to the porcelain insulators, requiring cleaning with a blower. However, the existing cleaning method directly uses a blower to blow air onto the porcelain insulators, and its structural performance is relatively simple. When the blower is working, the airflow acts on the porcelain insulators from top to bottom, which can easily lead to uneven airflow, and moisture and dust may still remain on the outer surface of the porcelain insulators, resulting in incomplete cleaning and reducing the cleaning effect.

[0004] Therefore, we need a reverse-flush ceramic bottle box for electrostatic precipitators to solve the above problems. Utility Model Content

[0005] This invention provides a backflush ceramic bottle box for an electrostatic precipitator to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A back-blowing ceramic bottle box for an electrostatic precipitator includes an electrostatic precipitator. A ceramic bottle box is fixedly connected to the left and right sides of the top of the electrostatic precipitator. A collection box is fixedly connected to the front side of the top of the electrostatic precipitator. Two L-shaped discharge pipes are fixedly connected to the left and right sides of the outer surface of the collection box. The outer surfaces of the left and right L-shaped discharge pipes penetrate the interior of the ceramic bottle box and are fixedly connected. An air pump is fixedly connected to the center of the front of the collection box.

[0007] The L-shaped discharge pipes on the left and right extend into the interior of the ceramic bottle box. A receiving hopper is fixedly connected to the outer surface of the L-shaped discharge pipe. Ceramic bottles are installed inside the ceramic bottle box.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example 1: As Figures 1 to 5As shown, this utility model provides a back-blowing ceramic bottle box for an electrostatic precipitator, including an electrostatic precipitator 1. The electrostatic precipitator 1 is the core main equipment, and the ceramic bottle box 2, which is fixedly connected through the top left and right sides of the electrostatic precipitator 1, provides a closed installation and protection space for the ceramic bottle 28 and related cleaning components, preventing external impurities from interfering with the insulation performance of the ceramic bottle 28. A collection box 3 is fixedly connected to the front top of the electrostatic precipitator 1, which is mainly used to collect dust and hot air discharged from the ceramic bottle box 2. An air pump 4 is fixedly connected to the center of the front of the collection box 3. When working, it can generate negative pressure to provide power for the flow of dust and hot air, so that they can smoothly enter the collection box 3 and be discharged through the air pump 4. In addition, the input end of the air pump 4 is fixedly connected through the inside of the collection box 3. Furthermore, a protective shell can be installed on the outer surface of the air pump 4 to protect it. Two L-shaped discharge pipes 21 are fixedly mounted on the left and right sides of the outer surface of the collection box 3. One end is connected to the collection box 3, and the other end extends into the interior of the ceramic bottle box 2 and is fixedly connected, forming a channel for the mixture of dust and gas to flow from the ceramic bottle box 2 to the collection box 3. The L-shaped discharge pipes 21 extend into the interior of the ceramic bottle box 2, and a receiving hopper 22 is fixedly connected to the outer surface of the L-shaped discharge pipes 21. When the air pump 4 is working, it sucks up the dust and water vapor near the receiving hopper 22, which more comprehensively receives the impurities cleaned from the ceramic bottle box 2, and also has the function of sucking up nitrogen. Example 2: Figures 1 to 5 As shown, a box body 23 is fixedly connected to the top of the ceramic bottle box 2. The box body 23 is the mounting carrier for the blower and heating components. The heating pipe 24 installed on the front side of the box body 23 is used to heat the incoming gas. A conveying pipe 25 is fixedly connected to the inner wall of the heating pipe 24, which undertakes the function of gas conveying, delivering the heated gas to the inside of the ceramic bottle box 2 and forming hot air. A square opening is opened on the upper rear side of the inner wall of the box body 23. A dustproof net 231 is fixedly connected to the square opening. When the blower 233 draws in outside air, it can filter dust and other impurities in the air, preventing impurities from entering the heating pipe 24 and the conveying pipe 25, and avoiding affecting the subsequent cleaning process. An installation port 232 is opened on the lower front side of the box body 23 to provide a position for the installation of the heating pipe 24, ensuring that the heating pipe 24 is fixed on the box body 23. A blower 233 is fixedly connected to the lower surface of the inner wall of the box body 23. When working, it can draw outside air into the box body 23 and then send it into the heating pipe 24 for heating. The heating tube 24 has several positioning rings 241 fixedly connected inside. These rings not only fix the heating wires 242 and ensure that the heating wires 242 are evenly distributed inside the heating tube 24, but also have several heating wires 242 fixed in a ring array on the surface of the positioning rings 241. When energized, these heating wires 242 generate heat to heat the air delivered by the blower 233, so that the hot air generated after heating can better clean the ceramic bottle 28.

[0019] The porcelain insulator 28 is a key insulating component in the electrostatic precipitator. A terminal 281 is fixedly connected to its top, extending to the outside of the insulator housing 2 for easy connection to an external circuit. An L-shaped rod is installed at the bottom of the insulator 28 to connect to the internal components of the electrostatic precipitator 1, enabling the electrode wire to be energized. The terminal 281 is L-shaped. A connecting component 27 is provided on the outer surface of the insulator 28 for fixing and supporting the pipeline structure related to the conveying process. A mounting bracket 29 is fixedly connected to the lower part of the outer surface of the connecting component 27 and is fixedly connected to the inside of the insulator housing 2. The mounting bracket 29 can fix the insulator 28 inside the insulator housing 2. Example 3: Figures 1 to 5 As shown, the cylindrical box 271 in the connecting assembly 27 serves as an intermediate carrier for gas distribution. The cylindrical box 271 is fixed to the inner wall of the porcelain bottle box 2. The conveying pipe 25 penetrates and is fixedly connected to both the porcelain bottle box 2 and the cylindrical box 271, allowing the gas conveyed by the conveying pipe 25 to smoothly enter the cylindrical box 271. A nitrogen inlet pipe 26, fixedly connected to the outer surface of the conveying pipe 25, passes through it and is connected to a nitrogen generator. The nitrogen generated by the nitrogen generator can enter the conveying pipe 25 through the nitrogen inlet pipe 26. Nitrogen is inert, effectively preventing impurities from forming on the surface of the porcelain bottle 28 due to oxidation, and also assisting in cleaning. Nitrogen gas enters the ceramic bottle box 2 under positive pressure, further protecting the ceramic bottle 28. Several pipes 272 are fixedly arranged in a ring array on the lower surface of the cylindrical box 271, which evenly distributes the gas in the cylindrical box 271 into each pipe 272. Several nozzles 273 are fixedly arranged in a ring array on the outer surface of the pipes 272 near the ceramic bottle 28, which can spray the gas in the pipes 272 onto the surface of the ceramic bottle 28 to blow away dust or water vapor on the surface of the ceramic bottle 28. The ring array of pipes 272 and nozzles 273 can ensure that the surface of the ceramic bottle 28 is thoroughly cleaned without any dead corners. Solenoid valves are installed on the outer surfaces of the delivery pipe 25, nitrogen inlet pipe 26, and L-shaped outlet pipe 21, which can control the opening and closing of each pipe respectively.

[0020] Working principle: When cleaning the porcelain insulator 28 is required, if hot air cleaning is selected, the solenoid valves of the conveying pipe 25 and the L-shaped discharge pipe 21 can be opened, the solenoid valve of the nitrogen inlet pipe 26 can be closed, the blower 233 and the heating wire 242 can be started, and the heated air enters the cylindrical box 271 through the conveying pipe 25, and then is sprayed onto the surface of the porcelain insulator 28 through the pipe 272 and the spray pipe 273. At the same time, the vacuum pump 4 is started to generate negative pressure, which draws the blown-down dust, hot air and water vapor into the collection box 3 through the receiving hopper 22 and the L-shaped discharge pipe 21, and then through the vacuum pump. 4. Discharge: If nitrogen is selected, the solenoid valves of nitrogen inlet pipe 26 and L-shaped outlet pipe 21 can be opened, and the solenoid valve of delivery pipe 25 can be closed. The nitrogen generated by the nitrogen generator is transported through the pipeline and enters delivery pipe 25 through nitrogen inlet pipe 26. Then it is sprayed onto porcelain bottle 28 through cylindrical box 271, pipe 272 and spray pipe 273. During the operation of electrostatic precipitator 1, nitrogen is introduced into porcelain bottle box 2 and a slightly positive pressure is maintained to form a gas seal barrier to prevent coal gas from leaking from inside electrostatic precipitator 1 into the interior of porcelain bottle box 2.

[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
