Description

Technical Field

[0001] This application relates to the technical field of tar capture equipment, and specifically to a tar capture and treatment equipment. Background Art

[0002] An electrostatic tar precipitator refers to a primary cooler for coke oven gas that uses the action of a high-voltage direct current electric field to separate tar droplets and gas. The electrostatic tar precipitator can be installed before or after the coke oven gas blower. Compared with a mechanical tar remover, the electrostatic tar precipitator has the characteristics of high tar capture efficiency, low resistance loss, and large gas treatment capacity.

[0003] Now, after connecting impurities and tar in the gas through an electrostatic tar precipitator, both the tar and impurities will fall to the bottom of the catcher. Subsequently, as the quantity increases, they will be discharged through a pipeline. However, the collected tar needs to be utilized later, so the impurities accompanying the tar need to be filtered later, resulting in the need for additional operations, which is rather cumbersome and will increase additional costs. Summary of the Utility Model

[0004] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. The summary is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments, but rather serves as a preface to the subsequent detailed description.

[0005] The embodiments of the present disclosure provide a tar capture and treatment equipment to solve the problem that the current tar catcher does not have the function of filtering and separating impurities in tar.

[0006] In some embodiments, a tar capture and treatment equipment includes a tar catcher body. An air inlet pipe is installed on the side wall at the bottom of the tar catcher body. An air outlet pipe is installed at the top of the tar catcher body. A base is installed at the bottom of the tar catcher body. A discharge pipe connected to the bottom of the tar catcher body is installed on the base. A treatment tank is provided below the base. A sealing cover is provided at the top of the treatment tank. A feed pipe corresponding to the discharge pipe is installed on the upper surface of the sealing cover. An installation cover in a circular shape is provided at the upper end inside the treatment tank. A filter screen is fixedly installed inside the installation cover. The outer wall of the installation cover abuts against the inner wall of the treatment tank. A fixed cover is fixedly provided outside the treatment tank near the installation cover. A toothed ring connected to the installation cover is rotatably provided inside the fixed cover. A driving gear is rotatably provided outside the treatment tank near the fixed cover.

[0008] The tar capture and treatment device provided by the embodiments of the present disclosure can achieve the following technical effects:

[0009] The filter screen in the installation cover of the present utility model can directly intercept and filter the impurities in the tar, without the need to use additional equipment for subsequent operations. While reducing costs, it is also convenient for operation. At the same time, the driving motor can drive the filter screen to rotate, so that the position of the entire filter screen below the feed pipe changes. As a result, the tar and impurities entering the treatment tank through the feed pipe will not be filtered only at one place of the filter screen, increasing the probability of blockage and extending the service life of the filter screen;

[0010] The scraper provided in the present utility model cleans the impurities intercepted on the filter screen to prevent the filter screen from being blocked and affecting the filtering effect of the impurities in the tar. The adjusting gear can facilitate the working drive of the toothed plate to move up and down, thereby controlling the toothed plate to adjust the distance between the scraper at the bottom of the second long rod and the filter screen, ensuring that the scraper can fully clean the filter screen.

[0027] Combined Figures 1-5 As shown, the embodiments of the present disclosure provide a tar capture and treatment device, including a tar capture body 1. An air inlet pipe 11 is installed on the side wall at the bottom of the tar capture body 1. An air outlet pipe 12 is installed on the top of the tar capture body 1. A base 13 is installed at the bottom of the tar capture body 1. A discharge pipe 14 connected to the bottom of the tar capture body 1 is installed on the base 13. A treatment tank 2 is provided below the base 13. A sealing cover 21 is provided at the top of the treatment tank 2. A feed pipe 22 corresponding to the discharge pipe 14 is installed on the upper surface of the sealing cover 21. It is worth noting that the discharge pipe 14 and the feed pipe 22 can be connected and installed through a sealing flange. Subsequently, the discharge pipe 14 and the feed pipe 22 are separated, and then the sealing cover 21 can be removed, and the filter screen 24 in the installation cover 23 can be taken out for cleaning or replacement. An installation cover 23 in a circular shape is provided at the upper end inside the treatment tank 2. A filter screen 24 is fixedly installed inside the installation cover 23. The outer wall of the installation cover 23 abuts against the inner wall of the treatment tank 2. A fixing cover 25 is fixedly provided outside the treatment tank 2 near the installation cover 23. A toothed ring 26 connected to the installation cover 23 is rotatably provided inside the fixing cover 25. A driving gear 29 is rotatably provided outside the treatment tank 2 near the fixing cover 25. The driving gear 29 can be meshed and connected with the toothed ring 26 inside the fixing cover 25.

[0028] Preferably, a driving motor 291 is fixedly installed above the driving gear 29 outside the installation cover 23. The output end of the driving motor 291 is coaxially and fixedly arranged on the driving gear 29. The arranged driving motor 291 can provide power for the driving gear 29, facilitating the operation of the staff. The driving gear 29 is a half-face gear. The half-face gear can intermittently drive the toothed ring 26 to rotate, so that the filter screen 24 inside the installation cover 23 connected to the toothed ring 26 can move after a certain period of time, increasing the filtering time of the filter screen 24 located below the feed pipe 22 for impurities.

[0029] Preferably, a vertically arranged clamping block 27 is fixedly arranged on the inner ring of the toothed ring 26. A clamping groove 28 corresponding to the clamping block 27 is opened at the bottom of the outer wall side of the installation cover 23. The clamping block 27 can be movably inserted into the clamping groove 28. When the installation cover 23 is installed in the treatment tank 2, the clamping groove 28 on the installation cover 23 is correspondingly inserted on the clamping block 27. At this time, the connection between the installation cover 23 and the toothed ring 26 will be completed, increasing the convenience of installation. With the connection between the toothed ring 26 and the installation cover 23, the toothed ring 26 can drive the installation cover 23 to rotate together, so that other positions on the filter screen 24 can move below the feed pipe 22, thus avoiding filtering only through one place of the filter screen 24 and increasing the probability of blockage.

[0030] Preferably, the sealing cover 21 and the treatment tank 2 are hermetically connected by a flange, and the hermetic connection by the flange can ensure the connection stability between the sealing cover 21 and the treatment pipe.

[0031] Preferably, a vertically arranged first long rod 3 is fixedly arranged at the center of the sealing cover 21. A vertically arranged second long rod 31 is movably inserted into the first long rod 3. A scraping plate 32 is fixedly arranged at the bottom of the second long rod 31. As the filter screen 24 rotates to the scraping plate 32, the arranged scraping plate 32 cleans the impurities intercepted on the filter screen 24, preventing the blockage of multiple places of the filter screen 24 from affecting the filtering effect of impurities in tar.

[0032] Preferably, a vertically arranged toothed plate 33 is fixedly provided outside the second long rod 31, and an adjusting gear 34 is meshed on the side wall of the toothed plate 33. The provided adjusting gear 34 can facilitate the work to drive the toothed plate 33 to move up and down, so as to control the toothed plate 33 to adjust the distance between the scraper 32 at the bottom of the second long rod 31 and the filter screen 24, ensuring that the scraper 32 can fully clean the filter screen 24; a rotating rod 35 is fixedly provided on the adjusting gear 34, and a worm gear 36 is fixedly provided at the end of the rotating rod 35. A worm 37 is meshed below the worm gear 36. When the provided worm 37 drives the worm gear 36 to rotate, the rotating rod 35 can drive the adjusting gear 34 to drive the toothed plate 33 to move. The use of the worm gear 36 and the worm 37 for driving can prevent the rotating rod 35 from reversing after adjustment, resulting in a change in the position of the toothed plate 33; a driving rod 38 is fixedly provided at the center of the worm 37, and the driving rod 38 can facilitate the staff to directly drive the worm 37 to rotate, facilitating the operation of the staff; a limiting strip 39 is fixedly provided outside the second long rod 31, and the second long rod 31 can be inserted into the first long rod 3 together with the limiting strip 39. Since the first long rod 3 is fixedly arranged on the sealing cover 21, the provided limiting strip 39 can prevent the second long rod 31 from rotating, and at the same time, the second long rod 31 can move on the first long rod 3.

[0033] Working principle: The gas enters the tar catcher body 1 through the intake pipe 11. After being processed, the processed gas will be discharged from the upper outlet pipe 12. The tar and impurities captured inside the tar catcher body 1 will fall to the bottom of the tar catcher body 1 and enter the treatment tank 2 through the discharge pipe 14 and the feed pipe 22. When the impurities in the tar pass through the filter screen 24, they will be filtered and intercepted. At this time, the tar can be discharged into other collection tanks through the pipeline at the bottom of the treatment tank 2 for collection. The impurities in the tar are separated during the discharge, eliminating the need for additional equipment for subsequent operation, reducing costs and facilitating operation at the same time.

[0034] The driving motor 291 can drive the driving gear 29 to rotate. At this time, the driving gear 29 will drive the toothed ring 26 meshed with it to rotate. The toothed ring 26 will drive the mounting cover 23 to rotate together. At this time, the filter screen 24 inside the mounting cover 23 rotates, changing the position of the entire filter screen 24 below the feed pipe 22. As a result, the tar and impurities entering the treatment tank 2 through the feed pipe 22 will not be filtered only at one place on the filter screen 24, increasing the probability of blockage and extending the service life of the filter screen 24.

[0035] When the mounting cover 23 rotates, the scraper 32 provided inside the treatment tank 2 will scrape the impurities remaining on the surface of the filter screen 24, ensuring good permeability of the filter screen 24 and preventing blockage from causing the tar to be unable to pass through.
