Description

Technical Field

[0001] This utility model relates to the field of settling device technology, specifically a settling device for dust-water separation in wet electrostatic precipitators. Background Technology

[0002] Wet electrostatic precipitators, as key equipment for industrial waste gas purification, are widely used in many industries such as power, steel, and chemical. During their operation, they generate a large amount of dust-laden water. If the water is discharged directly without effective treatment, it will not only waste water resources but also cause serious environmental pollution. Therefore, the sedimentation device for dust-water separation has become an indispensable and important component of wet electrostatic precipitator systems.

[0003] However, traditional sedimentation devices on the market currently have many drawbacks. In terms of dust-water separation efficiency, most traditional devices use simple gravity sedimentation, lacking targeted treatment methods for dust particles of different sizes. This makes it difficult for smaller dust particles to settle in a short time, resulting in a large number of fine impurities remaining suspended in the separated water, failing to meet increasingly stringent environmental emission standards. The filters of traditional sedimentation devices are often easily clogged by dust particles. Once the filters are clogged, it not only reduces the dust-water separation efficiency but also causes the internal pressure of the equipment to increase, affecting the normal operation of the equipment. Cleaning the filters is usually quite complicated, requiring specialized tools and technicians, and often necessitates shutdown. Utility Model Content

[0004] The purpose of this utility model is to provide a settling device for dust-water separation in wet electrostatic precipitators. It solves the technical problems of low dust-water separation efficiency, difficulty in removing dust particles of different sizes, complex equipment maintenance, easy clogging of the filter screen and difficulty in cleaning, etc. of traditional settling devices. It achieves the purpose of dust-water separation, easy maintenance, enhanced device sealing, and prevention of dust-containing water leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a settling device for dust-water separation in a wet electrostatic precipitator, comprising a settling tank, a graded settling installation part, and a graded settling filter part. Supporting legs are fixedly installed at equal intervals around the outer circumference of the settling tank, and supporting pads are fixedly installed on the bottom outer wall of each supporting leg. The graded settling installation part is located on the outer wall of the settling tank, and the graded settling filter part is located inside the settling tank.

[0006] Preferably, the graded settling installation part specifically includes: an outlet bend, which is set inside the settling tank; a fixing block, which is circumferentially fixed to the outer wall of the settling tank; an installation port, which is opened at the top of the settling tank; and an installation groove, which is circumferentially opened at the top outer wall of the settling tank.

[0007] Preferably, a sealing mounting plate is fitted inside the mounting groove, a rotating groove is opened on the top of each fixing block, a rotating rod is rotatably connected inside the rotating groove, a support plate is fixedly sleeved on the outer wall of the rotating rod, and a threaded sleeve is fixedly installed on the top of the support plate.

[0008] A fixing block is installed, which works in conjunction with the rotating rod, support plate, threaded sleeve, and threaded rod to effectively fix the sealing mounting plate. By rotating the rotating wheel, the threaded rod is screwed into the mounting positioning groove on the sealing mounting plate, which can apply stable and uniform pressure to the sealing mounting plate. This ensures that the sealing mounting plate is tightly fitted to the top of the settling tank, preventing dust and water leakage during the settling process, ensuring the sealing performance of the entire settling device, and thus improving the effect and efficiency of dust and water separation.

[0009] Preferably, the threaded sleeve has an internal threaded connection to a threaded rod, one end of which is fixedly connected to a rotating wheel, and the other end of which movably passes through the top outer wall of the support plate and extends to the bottom outer wall of the support plate.

[0010] Preferably, the top outer wall of the sealing mounting plate is provided with equidistant mounting grooves, the threaded rod is adapted to the mounting grooves, the top outer wall of the sealing mounting plate is connected to a water inlet pipe, and one end of the water outlet bend pipe movably penetrates the inner wall of the settling tank and extends to the outer wall of the settling tank.

[0011] Preferably, the graded sedimentation filtration section specifically includes: a fixed annular plate, fixedly installed on the inner wall of the sedimentation tank; an installation tank, fixedly installed between the fixed annular plate and the top of the inner wall of the sedimentation tank; a motor mounting bracket, fixedly installed on the top outer wall of the sealing mounting plate; a water inlet, opened on the sealing mounting plate; a sealing block, fixedly installed on the bottom outer wall of the sealing mounting plate; and a connecting fixing rod, circumferentially fixedly installed on the bottom outer wall of the sealing mounting plate.

[0012] An installation bucket is installed, which cooperates with the fixed circular plate to be securely installed between the top of the inner wall of the settling tank and the fixed circular plate, providing a reliable installation foundation for the entire graded settling filtration section. The installation bucket fits tightly with the sealing block and sealing ring at the bottom of the sealing installation plate, effectively preventing leakage of dust-laden water during the settling process. When dust-laden water flows into the installation bucket from the inlet pipe through the inlet, the sealing structure ensures that the water flow can only enter the graded filter settling screen tank for treatment according to the predetermined path, preventing water overflow. This not only improves the efficiency of dust-water separation but also avoids pollution to the surrounding environment.

[0013] Preferably, the water inlet is connected to the water inlet pipe, sealing rings are fixedly installed at equal intervals on the outer wall of the sealing block, the sealing block is adapted to the installation bucket, and a graded filter sedimentation screen bucket is fixedly sleeved at equal intervals on the outer wall of the connecting fixing rod.

[0014] A tiered filtration and settling screen is installed, which is tightly fitted with connecting rods and fixed inside the installation tank. The connecting rods provide stable support to ensure stability during settling. This stable installation method allows tiered filtration and settling screens of different sizes to be arranged in a predetermined order to filter and settle dust-laden water step by step. The dust-laden water first passes through the upper screen with a large aperture to initially filter out larger dust particles, and then enters the lower screen with a small aperture to further capture fine dust particles. This greatly improves the accuracy of dust-water separation and makes the separated water clearer.

[0015] Preferably, a motor is fixedly installed inside the motor mounting bracket, and a rotating rod is fixedly connected to the output end of the motor. The other end of the rotating rod movably penetrates the top outer wall of the sealing mounting plate and extends into the interior of the mounting barrel. Vortex rotating fans are fixedly fitted at equal intervals on the outer wall of the rotating rod, and the vortex rotating fans are respectively installed inside the graded filter settling screen barrel.

[0016] Equipped with a vortex fan, the high-speed rotation generates vortices that continuously wash the grading filter settling tank, preventing dust particles from accumulating and clogging the surface of the tank, keeping the filter clean, extending its service life, and reducing maintenance costs. Connected to a motor, the fan provides stable power, driving the fan to rotate at high speed, creating a powerful vortex inside the grading filter settling tank. Under the action of the vortex, dust-laden water and dust particles are accelerated to settle towards the tank wall and bottom due to the combined effects of centrifugal force and gravity, greatly shortening the settling time and improving separation efficiency.

[0017] This invention provides a settling device for dust-water separation in wet electrostatic precipitators. It has the following beneficial effects:

[0018] (1) The design of the graded sedimentation installation part makes the installation and disassembly of the sedimentation device simple and quick. The sealing installation plate is installed in the installation groove by snapping. This installation method does not require complicated tools and operations. Operators can easily install or disassemble it. At the same time, the rotating rod can rotate in the rotating groove of the fixed block, driving the support plate and its threaded sleeve to move. By rotating the rotating wheel, the threaded rod can be matched or separated from the installation positioning groove on the sealing installation plate. During equipment maintenance, simply rotate the rotating wheel to disengage the threaded rod from the installation positioning groove, and the graded sedimentation filter part can be easily removed for inspection, cleaning or replacement of parts inside the sedimentation tank. This greatly shortens the maintenance time and improves the maintenance efficiency.

[0019] (2) By setting up multi-layer graded filter settling screens, this utility model can filter and settle dusty water step by step. Dust particles of different sizes will be intercepted and settled in the corresponding layers of screens. Larger dust particles are first intercepted in the upper screens. As the water flows downward, smaller dust particles are further filtered in the lower screens. This can more effectively remove dust particles of different sizes. The motor drives the vortex fan to rotate at high speed in the graded filter settling screens. The centrifugal force and water flow disturbance generated by the vortex can accelerate the settling speed of dust particles and also play a self-cleaning role in the graded filter settling screens, maintaining the filtration performance of the screens.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0027] Addressing the existing problems of difficulty in removing dust particles of different sizes, complex equipment maintenance, and easy clogging and cleaning of filters, this utility model provides a preferred embodiment of a settling device for dust-water separation in wet electrostatic precipitators, for example... Figures 1-4 As shown: A settling device for dust-water separation in a wet electrostatic precipitator includes a settling tank 1, a graded settling mounting part 3, and a graded settling filter part 4. Supporting legs are fixedly installed at equal intervals around the outer circumference of the settling tank 1, and supporting pads 2 are fixedly installed on the bottom outer wall of the supporting legs. The graded settling mounting part 3 is located on the outer wall of the settling tank 1. The graded settling filter part 4 is located inside the settling tank 1.

[0028] The graded settling installation unit 3 specifically includes: an outlet bend 311, which is set inside the settling tank 1; a fixing block 312, which is fixedly installed on the outer wall of the settling tank 1 at equal intervals around the circumference; an installation port 319, which is opened at the top of the settling tank 1; and an installation groove 318, which is opened at equal intervals around the circumference on the top outer wall of the settling tank 1.

[0029] The mounting slot 318 is fitted with a sealing mounting plate 3111. The top of each fixing block 312 is provided with a rotating groove. The rotating groove is rotatably connected to a rotating rod 313. The outer wall of the rotating rod 313 is fixedly fitted with a support plate 314. The top of the support plate 314 is fixedly installed with a threaded sleeve 315.

[0030] The threaded sleeve 315 has a threaded rod 316 connected to its internal thread. One end of the threaded rod 316 is fixedly connected to a rotating wheel, and the other end of the threaded rod 316 movably passes through the top outer wall of the support plate 314 and extends to the bottom outer wall of the support plate 314.

[0031] The top outer wall of the sealing mounting plate 3111 is provided with mounting positioning grooves 3112 at equal intervals. The threaded rod 316 is adapted to the mounting positioning grooves 3112. The top outer wall of the sealing mounting plate 3111 is connected to the water inlet pipe 317. One end of the water outlet bend 311 movably penetrates the inner wall of the settling tank 1 and extends to the outer wall of the settling tank 1.

[0032] In this embodiment, the graded filter settling tank 4112 is installed inside the installation tank 412 by engaging the sealing mounting plate 3111 in the installation groove 318. The rotating rod 313 moves the support plate 314 and its threaded sleeve 315 to the appropriate position. The rotating wheel is rotated to screw the threaded rod 316 into the installation positioning groove 3112 on the top of the sealing mounting plate 3111, thus completing the fixing of the sealing mounting plate 3111. This effectively fixes the sealing mounting plate. By rotating the rotating wheel to screw the threaded rod into the installation positioning groove on the sealing mounting plate, a stable and uniform pressure can be applied to the sealing mounting plate. This ensures that the sealing mounting plate is tightly fitted to the top of the settling tank, preventing dust and water leakage during the settling process. Example 2:

[0033] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is further obtained: the graded sedimentation filtration section 4 specifically includes: a fixed annular plate 411, fixedly installed on the inner wall of the sedimentation tank 1; an installation tank 412, fixedly installed between the fixed annular plate 411 and the top of the inner wall of the sedimentation tank 1; a motor mounting bracket 417, fixedly installed on the top outer wall of the sealing mounting plate 3111; a water inlet 413, opened on the sealing mounting plate 3111; a sealing block 415, fixedly installed on the bottom outer wall of the sealing mounting plate 3111; and a connecting fixing rod 414, circumferentially fixedly installed on the bottom outer wall of the sealing mounting plate 3111.

[0034] The inlet 413 is connected to the inlet pipe 317. The outer wall of the sealing block 415 is fixedly equipped with sealing rings 416 at equal intervals. The sealing block 415 is compatible with the installation bucket 412. The outer wall of the connecting fixing rod 414 is fixedly fitted with a graded filter sedimentation bucket 4112 at equal intervals.

[0035] A motor 418 is fixedly installed inside the motor mounting bracket 417. A rotating rod 419 is fixedly connected to the output end of the motor 418. The other end of the rotating rod 419 movably passes through the top outer wall of the sealing mounting plate 3111 and extends into the interior of the mounting barrel 412. Vortex rotating fans 4111 are fixedly sleeved at equal intervals on the outer wall of the rotating rod 419. The vortex rotating fans 4111 are respectively installed inside the graded filter settling screen barrel 4112.

[0036] In this embodiment, the motor 418 is turned on, driving the rotating rod 419 to rotate. This causes the vortex fan 4111 to rotate at high speed inside the graded filter settling tank 4112, forming a vortex. Under the action of the vortex, larger dust particles in the dust-laden water are first intercepted in the uppermost or slightly above-average graded filter settling tank 4112 and settle to the bottom. As the water continues to flow downwards, smaller dust particles are further filtered and settled in the lower graded filter settling tank 4112, thus effectively filtering the dust-laden water. The system employs a step-by-step filtration and sedimentation process, where dust particles of different sizes are intercepted and settled in corresponding mesh bins. Larger dust particles are first trapped in the upper mesh bins, while smaller dust particles are further filtered in the lower mesh bins as the water flows downwards. This process effectively removes dust particles of different sizes. A motor drives a vortex fan to rotate at high speed within the staged filtration and sedimentation mesh bins. The centrifugal force generated by the vortex and the disturbance of the water flow accelerate the settling speed of the dust particles and also provide a self-cleaning effect for the staged filtration and sedimentation mesh bins, maintaining their filtration performance.

[0037] Working principle: When in use;

[0038] Step 1: Fix the supporting legs circumferentially at equal intervals on the outer wall of the settling tank 1, and then fix the supporting pad 2 on the bottom outer wall of the supporting legs to place the settling device stably. Install the sealing mounting plate 3111 into the mounting groove 318, install the graded filter settling screen 4112 inside the mounting tank 412, rotate the rotating rod 313 to move the supporting plate 314 and its threaded sleeve 315 to the appropriate position, rotate the rotating wheel to screw the threaded rod 316 into the mounting positioning groove 3112 on the top of the sealing mounting plate 3111 to complete the fixing of the sealing mounting plate 3111, and connect the water inlet pipe 317 to the top outer wall of the sealing mounting plate 3111 so that it is connected to the water inlet 413.

[0039] Step 2: Start the water supply system related to the wet electrostatic precipitator. The dust-laden water enters the graded filter settling screen 4112 inside the settling tank 1 through the water inlet pipe 317 and the water inlet 413.

[0040] Step 3: Turn on the motor 418. The motor 418 drives the rotating rod 419 to rotate, which in turn causes the vortex rotating fan 4111 to rotate at high speed inside the graded filter settling screen 4112, forming a vortex. Under the action of the vortex, the larger dust particles in the dust-laden water are first intercepted in the uppermost or slightly higher graded filter settling screen 4112 and settle to the bottom of the screen. As the water continues to flow downward, the smaller dust particles are further filtered and settled in the lower graded filter settling screen 4112.

[0041] Step 4: The clean water after grading and settling filtration is discharged from the settling tank 1 through the outlet bend 311, and can be recycled or discharged for further treatment.

[0042] Step 5: Periodically close the inlet pipe 317 to stop water intake, turn off the motor 418, rotate the wheel to unscrew the threaded rod 316 from the mounting positioning groove 3112, rotate the rotating rod 313 to remove the support plate 314, remove the sealing mounting plate 3111 from the mounting groove 318, clean the graded filter sedimentation screen 4112 to remove the deposited dust particles, and at the same time check the sealing condition of components such as the sealing block 415 and the sealing ring 416. If there is any damage, replace it in time. After cleaning, reinstall the sealing mounting plate 3111 and other components according to the installation method in Step 1, and prepare for the next dust-water separation operation.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
