Description

Technical Field

[0001] This utility model belongs to the field of flue gas purification technology, specifically, it relates to an electrostatic precipitator for industrial oil fume purification. Background Technology

[0002] Electrostatic precipitators use a high-voltage electric field to charge tar and dust particles in the gas. The charged particles move toward the collecting electrode and deposit under the influence of the electric field, thereby achieving gas-solid separation.

[0003] In existing electrostatic precipitators, uneven flue gas distribution leads to excessively high tar and dust concentrations in some areas, affecting overall efficiency. Often, an airflow distribution plate is installed to ensure even gas flow through the settling electrode. Since the distribution plate is positioned below the settling electrode, tar must pass through it before dripping into the bottom of the cylinder. However, with prolonged use, excessive tar accumulates on the distribution plate, clogging the air distribution holes and affecting purification efficiency. Furthermore, the tar dripping into the bottom of the cylinder adheres to the bottom wall, making it difficult to remove. Therefore, we propose an electrostatic precipitator for industrial oil fume purification. Utility Model Content

[0004] This invention provides an electrostatic precipitator for industrial oil fume purification to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An electrostatic precipitator for industrial oil fume purification includes two partitions coaxially fixedly installed inside a cylindrical body. Each partition has several through holes spaced circumferentially. A tubular precipitation electrode is coaxially disposed between the through holes on the two partitions. The upper and lower ends of the tubular precipitation electrode are fixedly connected to the two partitions, respectively. A corona electrode wire coaxially passes through the interior of each tubular precipitation electrode. The upper and lower ends of the corona electrode wire pass through the through holes on the two partitions, respectively. The upper end of the corona electrode wire is fixedly connected to an upper hanger, and the lower end is fixedly connected to a lower hanger. The frame and the lower hanger are fixedly connected to the inner wall of the cylinder. A flue gas stirring mechanism is provided inside the cylinder and below the lower hanger. An air inlet pipe is fixedly connected to the left side of the cylinder and to the left of the flue gas stirring mechanism. A truncated cone-shaped tar storage hopper is coaxially fixedly connected to the bottom end of the cylinder. A tar discharge pipe is coaxially fixedly installed at the bottom end of the tar storage hopper. A slide valve is coaxially fixedly installed at the bottom end of the tar discharge pipe. A scraper mechanism for scraping tar off the inner wall of the tar storage hopper is provided inside. An exhaust pipe is fixedly connected to the top side wall of the cylinder.

[0007] Furthermore, the flue gas stirring mechanism includes rotating shafts rotatably connected to the left and right sides of the mounting plate, and a plurality of stirring crossbars are equidistantly installed on the rotating shafts along the vertical direction. The left and right ends of the mounting plate are fixedly connected to the inner side wall of the cylinder, and a drive motor is fixedly installed on the top wall of the cylinder. The output shaft of the drive motor is connected to each rotating shaft for transmission.

[0008] Furthermore, a rotating rod is coaxially rotatably arranged inside the cylinder. The upper end of the rotating rod is rotatably connected to the top of the cylinder, and the lower end of the rotating rod passes vertically downward through two partitions and a mounting plate. The rotating rod is rotatably connected to the partitions and the mounting plate respectively. Synchronous pulleys are coaxially fixedly mounted on the outer sides of the two rotating shafts and the rotating rod. Each of the synchronous pulleys is connected by a synchronous belt drive, and the synchronous pulleys and the synchronous belt are located below the mounting plate. The output shaft of the drive motor is coaxially fixedly connected to the upper end of the rotating rod.

[0009] Furthermore, cleaning scrapers are respectively provided on the left and right sides of the inner wall of the tar storage hopper. The cleaning scrapers are inclined plates and abut against the inner wall of the tar storage hopper. The rotating rod is connected to the two cleaning scrapers in a transmission manner.

[0010] Furthermore, a rotating shaft is coaxially fixedly connected to the lower end of the rotating rod, and the cleaning scraper is fixedly connected to the rotating shaft via a connecting rod.

[0011] Furthermore, the upper and lower hangers are both annular frames, and the upper and lower ends of the corona electrode are fixedly connected to the annular frames respectively. The left and right ends of the annular frames are fixedly connected to fixing rods, and the fixing rods are fixedly connected to the inner side wall of the cylinder.

[0012] The technological advancements achieved by this invention compared to existing technologies, due to the aforementioned structure, are as follows: During operation, flue gas enters the cylinder through the inlet pipe. Then, the flue gas stirring mechanism is activated to uniformly stir the flue gas. At this point, the flue gas enters the tubular sedimentation electrode evenly. Without the need for an airflow equalization plate, the flue gas can be uniformly purified through each tubular sedimentation electrode, preventing the equalization holes of the airflow equalization plate from being blocked by tar. Furthermore, the scraper mechanism scrapes away the tar on the inner wall of the tar storage hopper, facilitating the discharge of deposited tar. This invention can stir the flue gas to ensure uniform passage through the tubular sedimentation electrode and can also scrape away the tar through the scraper mechanism, facilitating tar discharge.

[0022] The working principle and advantages of this utility model are as follows: the flue gas enters the cylinder 1 from the inlet pipe 6, and then the flue gas stirring mechanism is activated to stir the flue gas evenly. At this time, the flue gas will enter the tubular sedimentation electrode 4 evenly. There is no need to install an airflow equalization plate to purify the flue gas evenly through each tubular sedimentation electrode 4, avoiding the airflow equalization plate's equalization holes being blocked by tar. Furthermore, the scraper mechanism is activated to scrape off the tar on the inner wall of the tar storage hopper 7, making it convenient to discharge the deposited tar.

[0023] In a preferred embodiment of this utility model, the flue gas stirring mechanism includes rotating shafts 12 rotatably connected to the left and right sides of the mounting plate 11, and multiple stirring crossbars 13 are equidistantly mounted on the rotating shafts 12 along the vertical direction.
