Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic oil fume removal equipment, specifically, to a wet high-voltage electrostatic oil fume removal equipment. Background Technology

[0002] Currently, enterprises often need to use wet high-voltage electrostatic precipitators to treat oil fumes and other gases during production and processing. Wet electrostatic precipitators are devices that use the principle of electrostatics to purify oil fumes.

[0003] For example, a wet electrostatic precipitator for removing oil fumes disclosed in patent CN208131269U has a simple structure. It uses side air intake to distribute the exhaust gas evenly and uses flow equalization holes to ensure that the exhaust gas is evenly directed to the bottom, avoiding uneven purification. However, in actual use, the oil fume exhaust gas entering the housing through the air intake horn is not filtered, allowing larger particles in the oil fume exhaust gas to enter the electrostatic precipitator and easily damage its internal components. Therefore, it needs improvement. Utility Model Content

[0008] Preferably, the mounting component also includes a mounting plate, which is fitted over the rotating shaft. The side wall of the air inlet pipe has a notch for the mounting plate to extend into.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0030] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0031] like Figure 1 As shown, a wet high-voltage electrostatic precipitator for removing oil fumes in this embodiment includes a housing 100. Inside the housing 100, from top to bottom, there is a spray assembly, a high-voltage electrostatic adsorption assembly, and an oil collection tank 141. An air inlet pipe 101 located below the high-voltage electrostatic adsorption assembly is provided on the side wall of the housing 100. An air outlet pipe 102 located above the spray assembly is provided at the top of the housing 100. A detachable filter assembly is installed inside the air inlet pipe 101 through an installation assembly. A dispersing assembly is provided inside the housing 100 corresponding to the air inlet pipe 101. The dispersing assembly is used to disperse the flue gas entering the housing 100 through the air inlet pipe 101.

[0032] In actual use, the high-voltage electrostatic adsorption assembly includes an upper fixing plate 121 and a lower fixing plate 122 fixedly installed in the housing 100. Multiple oil collection pipes 123 are arranged in parallel between the upper fixing plate 121 and the lower fixing plate 122. The two ends of the oil collection pipes 123 pass through the upper fixing plate 121 and the lower fixing plate 122 respectively. The high-voltage electrostatic adsorption assembly also includes an upper electrode frame 131 fixed above the upper fixing plate 121 and a lower electrode frame 132 fixed below the lower fixing plate 122. An electrode wire 133 is arranged between the upper electrode frame 131 and the lower electrode frame 132, passing through the corresponding oil collection pipe 123. Specifically, the electrode wire 133 passes through the oil collection pipe 123 approximately along the axis of the oil collection pipe 123.

[0033] Among them, the external oily fumes enter the housing 100 through the air inlet pipe 101. The oily fumes entering the housing 100 move upward and enter the high-voltage electrostatic adsorption component and the spray component in sequence, and are discharged outside the housing 100 through the air outlet pipe 102.

[0034] Specifically, when the high-voltage electrostatic adsorption component is energized, a high-voltage electrostatic field is formed in the oil collection pipe 123 due to the action of the electrode wire 133. Under the action of the high-voltage electrostatic field, harmful substances such as oil fume particles in the oil fume exhaust gas flowing through the oil collection pipe 123 are adsorbed onto the pipe wall of the oil collection pipe 123. The purified oil fume exhaust gas continues to rise and is discharged from the housing 100 through the air outlet pipe 102 via the spray component. Thus, the oil fume exhaust gas is purified.

[0035] In this embodiment, the oil fume particles adsorbed on the pipe wall of the oil collection pipe 123 continuously accumulate and form oil stains. Therefore, the spray assembly is turned on at regular intervals to flush the pipe wall of the oil collection pipe 123, thereby achieving better cleaning of the oil collection pipe 123 and ensuring the purification effect of the high-voltage electrostatic adsorption assembly on the oil fume exhaust gas.

[0036] In this embodiment, the oil collection tank 141 is located at the bottom of the housing 100, and the air inlet pipe 101 is located on the side wall of the housing 100 between the oil collection tank 141 and the high-voltage electrostatic adsorption component. The oily waste liquid after the spray component washes the oil collection pipe 123 falls due to gravity and is collected in the oil collection tank 141.

[0037] Specifically, the oil collection tank 141 is provided with a drain pipe 103 extending out of the housing 100. The drain pipe 103 is used to discharge the oil fume waste liquid in the oil collection tank 141 so that the oil fume waste liquid can be treated in the future.

[0038] In this embodiment, the spray assembly includes opposing spray plates 111, and a plurality of spray pipes 112 are evenly distributed between the spray plates 111. Spray nozzles are evenly distributed on the spray pipes 112. The spray pipes 112 are connected to the existing water supply system, which enables the spray nozzles to spray clean water onto the oil collection pipe 123 below, thereby cleaning the oil collection pipe 123.

[0039] In this embodiment, by setting the filter component, the filter component can filter the oil fume exhaust gas entering the housing 100 through the air inlet pipe 101 during actual use, thereby filtering out impurities with larger particle sizes in the oil fume exhaust gas to prevent them from entering the housing 100 and causing damage to its internal components.

[0040] The filter assembly is designed to be detachable, allowing it to be removed for cleaning and maintenance when it becomes clogged.

[0041] In this embodiment, the dispersing component is designed to disperse the oily fumes entering the housing 100 through the air inlet pipe 101, allowing the oily fumes to flow more evenly through the oil collection pipe 123. This prevents the oily fumes from concentrating and causing the oil collection pipe 123 at the edge to have no oily fumes flowing, thus ensuring the high-voltage electrostatic adsorption component's treatment effect on the oily fumes.

[0042] Combination Figure 2 and Figure 3 As shown, in this embodiment, the outer wall of the air inlet duct 101 is provided with a slot for inserting and installing the filter assembly; the filter assembly includes a filter frame 210 and a filter screen 211 disposed in the filter frame 210. The side wall of the filter frame 210 is provided with a slot 301. The mounting component includes a rotating shaft 310 rotatably disposed on the outer wall of the air inlet duct 101. One end of the rotating shaft 310 extends into the air inlet duct 101, and the end of the rotating shaft 310 extending into the air inlet duct 101 is provided with a locking block 311. The rotation of the rotating shaft 310 is used to drive the locking block 311 to slide into or out of the slot 301, thereby realizing the installation and removal of the filter frame 210 in the air inlet duct 101.

[0043] In this embodiment, by setting up the filter frame 210 and the filter screen 211, the filter screen 211 can filter the oil fume exhaust gas when the filter frame 210 is inserted into the air inlet pipe 101 through the slot.

[0044] In this embodiment, in order to ensure the sealing when the filter assembly is inserted, a sealing strip is wrapped on the outer wall of the filter frame 210. When the filter frame 210 is inserted into the air inlet pipe 101 through the slot, the sealing strip presses against the side wall of the air inlet pipe 101 to ensure the sealing of the filter assembly installation.

[0045] In actual use, in order to facilitate the pull-out and insertion of the filter frame 210 in the air inlet pipe 101, the filter frame 210 is provided with a handle 212 on the side wall outside the air inlet pipe 101.

[0046] In order to fix the filter frame 210 inserted into the air inlet pipe 101, in this embodiment, when the filter frame 210 is inserted into the air inlet pipe 101, the locking block 311 is locked into the locking groove 301 by rotating the rotating shaft 310, which can fix the filter frame 210. When the locking block 311 is released from the locking groove 301 by rotating the rotating shaft 310, the filter frame 210 is released, so that the filter frame 210 can be pulled out in the air inlet pipe 101.

[0047] In this embodiment, the mounting component also includes a mounting plate 220, which is sleeved around the rotating shaft 310. The side wall of the air inlet pipe 101 is provided with a notch for the mounting plate 220 to extend into. The outer side of the mounting plate 220 extends outward to form a mounting part 321, which is fixed to the air inlet pipe 101 by screws. The mounting plate 220 is provided with a fixing component for fixing the rotating shaft 310.

[0048] In this embodiment, combined with Figure 4 As shown, a groove is provided on the side of the mounting plate 220 away from the mounting part 321, and a bearing 400 is installed in the groove. The rotating shaft 310 is mounted on the mounting plate 220 through the bearing 400.

[0049] The notch and mounting part 321 allow for better assembly and disassembly of the mounting components on the outer wall of the air inlet duct 101.

[0050] In this embodiment, a screw cap 230 is provided at the end of the rotating shaft 310 located outside the air inlet pipe 101. This allows the operator to drive the rotating shaft 310 to rotate by screwing the screw cap 230, so as to disassemble and assemble the filter assembly. The operation is simple and convenient.

[0051] In order to restrict the rotation of the card block 311 and ensure that the card block 311 is located within the card slot 301, combined with Figure 3 As shown, a positioning post is provided on the side of the mounting plate 220 away from the mounting part 321. When the locking block 311 rotates and overlaps on the positioning post, it can better keep the locking block 311 in the slot 301 and fix the filter frame 210. At this time, in order to avoid the accidental rotation of the rotating shaft 310, in this embodiment, the rotating shaft 310 can be fixed by the fixing component to prevent the filter component from being poorly fixed due to the accidental rotation of the rotating shaft 310 during use.

[0052] Combination Figure 4 and Figure 5As shown, in this embodiment, the fixing component includes a clamping member sleeved on the outside of the rotating shaft 310 and fixedly connected to the mounting plate 220, and a rotating member 240 threadedly connected to the outside of the clamping member. The clamping member includes a fixing part 410 and a deformable part 420. The outer side wall of the deformable part 420 is provided with a clamping inclined surface along its circumference. The rotating member 240 includes a rotating part 510 and a pressing part 520. The rotating part 510 is threadedly connected to the fixing part 410. The inner side wall of the pressing part 520 is provided with a pressing inclined surface that cooperates with the clamping inclined surface. When the rotating part 510 is threadedly connected to the fixing part 410, it is used to drive the pressing inclined surface to press the clamping inclined surface so that the deformable part 420 clamps the rotating shaft 310.

[0053] In this embodiment, the outer side wall of the fixing part 410 is provided with an external thread, and the inner side wall of the rotating part 510 is provided with an internal thread. Through the cooperation between the two, the threaded connection of the rotating part 240 outside the clamping part can be better realized.

[0054] The fixing component is made of plastic, which enables the deformable part 420 to have a deformation clamping function. Specifically, the deformable part 420 is provided with a gap groove along its circumference, thereby improving the deformation clamping of the deformable part 420. In actual use, when the rotating part 510 rotates toward the mounting plate 220 and is threaded onto the fixing part 410, the extrusion slope can press against the clamping slope, that is, the extrusion part 520 presses against the deformable part 420, so that the deformable part 420 deforms and clamps the rotating shaft 310, thereby fixing the rotating shaft 310 and preventing it from rotating accidentally. When the rotating part 510 is rotated away from the fixing part 410, the extrusion slope can be moved away from the clamping slope, thereby resetting the deformable part 420 and releasing its clamping fixation on the rotating shaft 310, so that the rotating shaft 310 can rotate, and thus the filter assembly can be disassembled and assembled.

[0055] In actual use, in order to facilitate the operator to rotate the rotating part 240, friction textures are provided on the outer side wall of the rotating part 240 along its circumference.

[0056] Combination Figure 6 As shown, in this embodiment, the dispersing component includes a base plate 151, on which a rotatable rotating rod is provided via a motor 610, and dispersing plates 153 are evenly distributed on the rotating rod.

[0057] In actual use, the base plate 151 is fixedly installed inside the housing 100, and the rotating rod and the dispersing plate 153 are installed at the center of the base plate 151. The dispersing plate 153 is arranged along the axial direction of the rotating rod, so that the rotating rod rotates and drives the dispersing plate 153 to rotate, thereby dispersing the oily fumes entering the air inlet pipe 101 to avoid the oily fumes from being concentrated.

[0058] Specifically, the motor 610 is a waterproof motor, which is fixedly installed on the lower side of the base plate 151. The motor 610 can better drive the rotating rod to rotate, thereby dispersing the oil fume exhaust gas.

[0059] In actual use, in order to ensure that the rotating rod is stably rotated and installed inside the housing 100, a mounting plate 152 located below the electrode lower frame 132 is fixedly installed inside the housing 100, and the upper end of the rotating rod is also rotatably mounted on the mounting plate 152 via a bearing.

[0060] In this embodiment, in order to allow the oily fumes generated by the spraying assembly to enter the oil collection tank 141 for collection, a guide shroud 620 covering the motor 610 is provided on the lower side of the base plate 151 along the circumference of the rotating rod, and guide grooves 630 communicating with the outside of the guide shroud 620 are evenly distributed on the base plate 151.

[0061] The guide shroud 620 and the guide channel 630 are designed to guide the oily waste liquid flowing from the guide channel 630 to the oil collection tank 141, thus preventing the oily waste liquid from flowing to the motor 610 and affecting its use.

[0062] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
