Description

Technical Field

[0001] This invention relates to the field of industrial waste gas purification technology, and in particular to a high-efficiency mist separator device. Background Technology

[0002] In industrial production processes, many steps generate gas-liquid mixtures containing mist. For example, in chemical production, power generation, and metallurgy, gases often carry a large number of fine liquid droplets (mist) after cooling, washing, and reaction operations. If these mists are released directly without effective separation, it will not only waste resources (e.g., the liquid may contain valuable chemical substances), but also pollute the environment (e.g., emissions into the atmosphere may form harmful substances such as acid mist), and may also affect the normal operation of subsequent process equipment (e.g., clogging pipes, corroding equipment).

[0003] Currently, various mist separators exist on the market, but most suffer from low separation efficiency and difficulty in cleaning. Some traditional mist separators use only a single separation method, making it difficult to effectively separate mist particles of different sizes, resulting in high concentrations of mist in the exhaust gas, which fails to meet increasingly stringent environmental protection requirements.

[0004] Moreover, after long-term operation, dirt will accumulate inside the separator, affecting the separation effect. However, existing cleaning methods are often not thorough enough, or the cleaning process is complicated and costly. Therefore, this application proposes a high-efficiency mist separator device to provide a new technical solution to solve the technical problems mentioned above. Summary of the Invention

[0005] Therefore, it is necessary to provide a high-efficiency mist separator device to address the aforementioned technical problems. This device features a dedicated cleaning component. When internal cleaning is required, external water is supplied through an annular distribution pipe to each cleaning nozzle. Simultaneously, a drive component uses steel cables to rotate the cleaning nozzles, with a flexible sealing plate following the rotation. This design allows the cleaning nozzles to thoroughly clean the interior of the cylinder during rotation, effectively removing dirt accumulated on the inner wall and separation layer during separation. This ensures long-term stable operation and high-efficiency separation performance. Compared to traditional mist separators, this device offers a more thorough cleaning method, significantly reducing the decrease in separation efficiency caused by dirt accumulation, and lowering maintenance costs and downtime.

The lower end of the return spring is in contact with the extension plate, and the upper end of the return spring is in contact with the bottom of the A-shaped drive plate.

[0012] In a preferred embodiment of the high-efficiency mist separator device provided by the present invention, a movable frame is slidably connected to the upper part of the annular frame, and the two sides of the movable frame extend to the outer and inner sides of the annular frame, respectively.

Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] Example 1

[0022] Please refer to Figure 1 - Figure 7 A high-efficiency mist separator device, comprising: The cylinder (1) has an inlet port (2) on the lower part of one side for the gas-liquid mixture to be processed to enter, and an outlet port (3) on the upper part of the other side for the gas after separation to be discharged. The cylinder (1) has a primary inertial separation layer (4), a secondary baffle separation layer (5), and a senior wire mesh separation layer (6) arranged from bottom to top inside. The primary inertial separation layer (4), the secondary baffle separation layer (5), and the senior wire mesh separation layer (6) are located between the inlet port (2) and the outlet port (3) for gradually separating the gas-liquid mixture in different ways. The bottom of the cylinder (1) has a drain port (7) for discharging the dirt generated during the separation process. The primary inertial separation layer 4 consists of 20 arc-shaped guide vanes. The radius of curvature of the vanes is 1.3 times the length of the vanes (approximately 780 mm), the length of the vanes is 0.7 times the inner diameter of the separator (approximately 980 mm), the thickness is 4 mm, and the spacing is 25 mm. It uses inertial force to cause large-diameter mist droplets (≥10 μm) to collide with and adhere to the arc-shaped guide vanes, and then agglomerate into large droplets and slide down along the arc-shaped guide vanes, initially removing 60%-70% of the mist droplets in the flue gas. The intermediate baffle separation layer 5 consists of 6 sets of parallel "Z"-shaped baffle units, each set containing 25 baffles. The baffles are made of 316L stainless steel, with a plate spacing of 18mm, a plate thickness of 2.5mm, and a baffle angle of 50°. The flue gas flows in a tortuous manner between the baffles. Medium-sized droplets (5-10μm) collide with and are intercepted by the baffles during the turning process, further agglomerating into larger droplets, achieving a separation efficiency of up to 85%. The advanced wire mesh separation layer 6 is composed of five layers of 316L stainless steel wire mesh, with a total thickness of 60mm, a wire diameter of 0.25mm, a mesh size of 0.7mm, and an open area ratio of 75%. Stainless steel support grilles with a spacing of 25mm are installed at both ends of the wire mesh layer. Utilizing the interception, inertial collision, and diffusion mechanisms of the wire mesh, it deeply separates minute droplets (≤5μm), ensuring that the final emission particulate concentration is ≤15mg / m³.

[0023] The cleaning component 8 is located above the advanced wire mesh separation layer 6 and is used to clean the inside of the device. The outer side of the cylinder 1 is fixedly connected to the protective shell 9, and the cleaning component 8 is located inside the protective shell 9.

[0024] Specifically, the cleaning assembly 8 includes multiple cleaning nozzles 10 arranged in a ring array around the cylinder 1. The cleaning nozzles 10 and the cylinder 1 are rotatably connected. The output end of the cleaning nozzle 10 is located inside the cylinder 1, and a flexible sealing plate 12 is sleeved on the outside of the output end of the cleaning nozzle 10. The flexible sealing plate 12 fits against the inner wall of the cylinder 1 and can move synchronously along the inner surface of the cylinder 1 with the movement of the cleaning nozzle 10 to prevent water leakage during the cleaning process. Furthermore, the cleaning assembly 8 also includes an annular diverter pipe 11, which is located outside the cylinder 1 and is fixedly connected to the cylinder 1. The annular diverter pipe 11 is connected to an external water source and is connected to the cleaning nozzle 10 through the diverter pipe. It is used to distribute water from the external water source to each cleaning nozzle 10. An elastic element is provided between the annular diverter pipe 11 and the cleaning nozzle 10 to pull the cleaning nozzle 10 back to its original position after the rotation cleaning action is completed. Furthermore, the cleaning assembly 8 also includes a steel wire rope 13, which is disposed on the outside of the cylinder 1 and located below the cleaning nozzle 10. The end of the cleaning nozzle 10 away from the cylinder 1 is connected to the drive assembly 14 via the steel wire rope 13.

[0025] Specifically, the drive assembly 14 includes an annular frame 15, which is sleeved on the outside of the cylinder 1 and fixedly connected to the cylinder 1. An movable groove 16 is provided on the outside of the annular frame 15. An A-shaped drive plate 17 is vertically slidably connected inside the movable groove 16 at a position corresponding to the cleaning nozzle 10. The lower end of the steel wire rope 13 is connected to the corresponding A-shaped drive plate 17. A guide wheel 18 is provided on the outside of the annular frame 15 at a position corresponding to the steel wire rope 13. A pressure wheel 20 is provided on the inside of the movable groove 16 and can move along the movable groove 16.

[0026] The wire rope 13 is fixedly connected to both ends with fixing bolts 22. The wire rope 13 is detachably connected to the corresponding cleaning nozzle 10 and the corresponding A-shaped drive plate 17 through the fixing bolts 22 at the ends, which facilitates installation and maintenance.

[0027] Furthermore, an extension plate 23 is fixedly connected to the outer side of the cylinder 1. A fixing post 24 is vertically fixedly connected to the upper end of the extension plate 23 at a position corresponding to each A-shaped drive plate 17. The upper part of the fixing post 24 is inserted into the A-shaped drive plate 17. A return spring 25 is sleeved on the outer side of the fixing post 24. The lower end of the return spring 25 is in contact with the extension plate 23, and the upper end of the return spring 25 is in contact with the bottom of the A-shaped drive plate 17, which is used to assist the A-shaped drive plate 17 in resetting after it moves.

[0028] Through the above structural design, when this high-efficiency mist separator is in operation, the gas-liquid mixture enters the cylinder 1 from the inlet port 2, and is sequentially separated by the primary inertial separation layer 4, the intermediate baffle separation layer 5, and the advanced wire mesh separation layer 6. The separated gas is discharged from the outlet port 3, and the contaminants are discharged from the drain port 7. When it is necessary to clean the inside of the device, the external water source is distributed to each cleaning nozzle 10 through the annular diversion pipe 11. At the same time, the drive component 14 drives the cleaning nozzle 10 to move through the steel wire rope 13, and the flexible sealing plate 12 moves accordingly, performing all-round cleaning of the inside of the cylinder 1.

[0029] Example 2

[0030] The high-efficiency mist separator device provided in Example 1 is further optimized, specifically, as follows: Figure 7As shown, a movable frame 19 is slidably connected to the upper part of the annular frame 15. The two sides of the movable frame 19 extend to the outer and inner sides of the annular frame 15, respectively. The pressure roller 20 is rotatably connected to the movable frame 19 located on the outer side of the annular frame 15. A drive motor 21 is fixedly connected to the movable frame 19 located on the inner side of the annular frame 15. A drive gear 28 is fixedly connected to the output end of the drive motor 21. A mating tooth 27 that meshes with the drive gear 28 is provided on the inner side of the annular frame 15. The drive gear 28 and the mating tooth 27 are meshed together. The drive motor 21 drives the drive gear 28 to rotate, thereby causing the movable frame 19 to slide along the annular frame 15, thereby driving the pressure roller 20 to move. Thus, the pressure roller 20 moving inside the movable groove 16 presses down on the A-shaped drive plate 17 at the corresponding position in sequence, thereby pulling the corresponding cleaning nozzle 10 to rotate through the wire rope 13, thereby changing the cleaning angle of the cleaning nozzle 10.

[0031] Furthermore, there are multiple pressure rollers 20, and the number of movable frames 19 corresponds to the number of pressure rollers 20. Multiple movable frames 19 are rotatably connected to the corresponding pressure rollers 20, and the tops of multiple movable frames 19 are fixedly connected through a linkage frame 26 to realize the synchronous movement of multiple pressure rollers 20.
