Description

Technical Field

[0001] This utility model relates to the field of cathode wire technology, specifically a novel cathode wire for wet electrostatic precipitators. Background Technology

[0002] A wet electrostatic precipitator (WESP) is an air purification device that combines the characteristics of electrostatic and wet dust removal. Its working principle involves applying tens of thousands of volts of DC high voltage between the anode plate (cylinder) and the cathode wire, creating a corona layer around the corona wire. This ionizes the air, generating a large number of negative ions and a small number of positive ions. Dust particles collide with these ions, becoming charged. Under the influence of the electric field, the charged dust particles move towards the opposite electrode and are adsorbed onto the collecting electrode plate or collection tube. Periodic flushing removes the dust with the flowing flushing liquid, preventing the re-entrainment of collected dust. The electrode system of a wet electrostatic precipitator, including the cathode wire and anode plate, is the key component for generating the electric field and adsorbing dust. The cathode wire of a wet electrostatic precipitator is typically suspended vertically inside the precipitator, hanging from the top frame fixing point to the lower fixing device, maintaining a straight line. This promotes a uniform distribution of the electric field, ensuring stable discharge and efficient dust collection.

[0003] For example, Chinese Patent CN205966181U discloses a cathode wire for a wet electrostatic precipitator, including an integrally formed cathode rod (1). The cathode rod (1) is provided with: a discharge body (2), which is arranged around the outer wall of the cathode rod (1) in a plate-like gear shape and located in the axial direction of the cathode rod (1); a swirling fluid (3), which is arranged around the outer wall of the cathode rod (1) and spaced apart from the discharge body (2) on the cathode rod (1), including multiple spaced-apart swirling blades (31); and connecting pieces (4), which are located at both ends of the cathode rod (1). The cathode rod (1) is connected to the cathode frame through the connecting pieces (4). This cathode wire for a wet electrostatic precipitator has a high corona current density and, in conjunction with the swirling blades, generates centrifugal swirling current, increasing the approach velocity of charged particles and thus improving the dust removal efficiency of the wet electrostatic precipitator.

[0004] In actual use, the length of the cathode wire described in this solution cannot be adjusted according to the actual situation. The length of a cathode wire is limited. When it is necessary to increase the length of the cathode wire, the two cathode wires are usually aligned and welded together. The welding process is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a novel cathode wire for a wet electrostatic precipitator to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A novel cathode wire for a wet electrostatic precipitator includes a cathode wire body, which comprises a pair of cathode rods. A first connector and a second connector are respectively installed on the outer sides of the cathode rods. The first and second connectors are used to connect the pair of cathode wire bodies. The first connector includes a lower connecting seat, on which an internally threaded cylinder is installed at the center of its top surface at the end furthest from the cathode rod. Vertical grooves are formed on both outer sides of the internally threaded cylinder, and horizontal grooves are formed on one side of the internally threaded cylinder located at the vertical grooves. The second connector includes an upper connecting seat, on which a dust cover is installed on its top surface. Mounting holes are formed inside both the upper connecting seat and the dust cover at the end furthest from the cathode rod. An outer cylinder is connected between the pair of mounting holes via a bearing, and a pair of movable blocks are connected to the inner wall of the outer cylinder. Furthermore, adjacent vertical and horizontal slots are connected, adjacent first and second connecting members are connected, and two moving blocks are arranged opposite each other, with each moving block located inside the end of the two horizontal slots away from the vertical slot. The outer wall of the moving block slides in cooperation with the inner wall of the vertical and horizontal slots. The beneficial effect of adopting the above-mentioned further solution is that, since the vertical and horizontal slots are connected, the second connecting member on the right side of one cathode wire body and the first connecting member on the left side of another cathode wire body overlap each other. The outer cylinder at one end of the upper connecting seat is sleeved outside the inner threaded cylinder of the lower connecting seat. At this time, a pair of moving blocks on the inner wall of the outer cylinder are located at the lowest end of the vertical slot through the vertical slot. Then, the outer cylinder rotates, causing the pair of moving blocks to rotate to the end of the horizontal slot away from the vertical slot under the action of the vertical slot. The outer cylinder and the inner threaded cylinder are connected, the upper connecting seat and the lower connecting seat are connected, and the second connecting member on the right side of the cathode wire body and the first connecting member on the left side of another cathode wire body are connected, thus realizing the connection between a pair of cathode wire bodies.

[0008] Furthermore, a first gear is sleeved on the outside of the outer cylinder, and a rotating shaft is rotatably connected between the inner top surface of the dust cover and the top surface of the upper connecting seat. A second gear is sleeved on the outside of the rotating shaft, and the first gear and the second gear mesh with each other.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting a dust cover, the first gear and the second gear are protected from dust, and dust is prevented from adhering to the surface of the first gear and the second gear. Through the cooperation of the rotating shaft, the second gear, the first gear and the outer cylinder, when the rotating shaft rotates, it drives the second gear to rotate, and the outer cylinder is rotated under the meshing action of the second gear and the first gear, so that the position of the moving block on the inner wall of the outer cylinder changes inside the transverse groove.

[0010] Furthermore, a hollow ring plate is installed on the top surface of the dust cover on the side away from the outer cylinder. The upper end of the rotating shaft extends through the hollow ring plate to the outside. Limiting seats are connected to both sides of the top surface of the hollow ring plate. Slots are provided inside the pair of limiting seats and the rotating shaft. A plug is provided between the three slots. The beneficial effect of adopting the above-mentioned further solution is that by setting the hollow ring plate, the inner wall of the hollow ring plate is clearance-fitted with the outer wall of the rotating shaft, thus not affecting the rotation of the rotating shaft. Through the cooperation of the limiting seats, slots, and plug, the cooperation between the plug and the slot can limit and fix the rotating shaft. When the first connecting piece and the second connecting piece are connected, inserting the plug can prevent the rotating shaft from rotating arbitrarily.

[0011] Furthermore, the bottom surface of the outer cylinder is in contact with the top surface of the lower connecting seat at the end away from the cathode rod, and the inner wall of the outer cylinder is in clearance fit with the outer wall of the internally threaded cylinder.

[0012] The beneficial effect of adopting the above-mentioned further solution is that when the outer cylinder inside the upper connecting seat on the right side of one cathode wire body is aligned with the inner threaded cylinder inside the lower connecting seat on the left side of another cathode wire body and pressed down, the inner threaded cylinder is located inside the outer cylinder, and the bottom surface of the outer cylinder and the top surface of the lower connecting seat at the end away from the cathode rod are in contact with each other. At this time, the arc-shaped end of the upper connecting seat and the arc-shaped end of the lower connecting seat are in contact with the inner wall of the arc-shaped groove of the lower connecting seat and the inner wall of the arc-shaped groove of the upper connecting seat, respectively, so that the first connecting piece and the second connecting piece overlap each other.

[0013] Furthermore, the lower connecting seat has a circular hole inside at the end away from the cathode rod, and the central axes of the circular hole, the internal threaded cylinder, and the outer cylinder (34) are collinear.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, by making the central axes of the round hole, the internal threaded cylinder, and the outer cylinder collinear, it is convenient for one end of the bolt fastener to pass through the round hole and the internal threaded hole and rotate, thereby fixing the connection of a pair of cathode rods in a designated position.

[0015] Furthermore, both the front and back sides of the pair of cathode rods are connected with several serrated tips.

[0016] The advantage of adopting the above-mentioned further scheme is that by setting several serrated tips on the front and back of the cathode rod, the discharge efficiency is improved.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: When the outer cylinder inside the upper connecting seat on the right side of one cathode wire body is aligned with the internally threaded cylinder inside the lower connecting seat on the left side of another cathode wire body and pressed down, the internally threaded cylinder is located inside the outer cylinder. The bottom surface of the outer cylinder and the top surface of the lower connecting seat at the end furthest from the cathode rod are in contact. At this time, the arc-shaped end of the upper connecting seat and the arc-shaped end of the lower connecting seat are respectively in contact with the inner wall of the arc-shaped groove of the lower connecting seat and the inner wall of the arc-shaped groove of the upper connecting seat, causing the first connecting piece and the second connecting piece to overlap. Since the vertical groove and the horizontal groove are connected, a pair of moving blocks on the inner wall of the outer cylinder are located at the lowest end of the vertical groove. Through the cooperation of the rotating shaft, the second gear, the first gear, and the outer cylinder, when the rotating shaft rotates, it drives the second gear to rotate, and the second gear and the first... The meshing of gears causes the outer cylinder to rotate, which in turn changes the position of the moving blocks on the inner wall of the outer cylinder within the transverse groove. This causes a pair of moving blocks to rotate to the end of the transverse groove away from the vertical groove under the action of the vertical groove. The outer cylinder and the internal threaded cylinder are connected, as are the upper and lower connecting seats. The second connecting piece on the right side of the cathode wire body and the first connecting piece on the left side of the other cathode wire body are connected, thus connecting a pair of cathode wire bodies. Through the cooperation of the limiting seat, slot, and insert rod, the insertion rod and slot can limit and fix the rotating shaft. When the first and second connecting pieces are connected, inserting the insert rod can prevent the rotating shaft from rotating arbitrarily. By ensuring that the central axes of the round hole, the internal threaded cylinder, and the outer cylinder are collinear, it is easy for one end of the bolt fastener to pass through the round hole and the internal threaded hole and rotate, thus fixing the connection of a pair of cathode rods in the designated position.

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] Please see Figures 1-5This utility model provides a technical solution: adjacent vertical grooves 24 and horizontal grooves 25 are connected, adjacent first connecting members 2 and second connecting members 3 are connected, two moving blocks 35 are arranged opposite each other, and the two moving blocks 35 are respectively arranged inside the ends of the two horizontal grooves 25 away from the vertical grooves 24. The outer wall of the moving block 35 slides with the inner wall of the vertical groove 24 and the horizontal groove 25. A first gear 36 is sleeved on the outside of the outer cylinder 34. A rotating shaft 37 is rotatably connected between the inner top surface of the dust cover 32 and the top surface of the upper connecting seat 31. A second gear 38 is sleeved on the outside of the rotating shaft 37. The first gear 36 and the second gear 38 mesh with each other. Since the vertical grooves 24 and horizontal grooves 25 are connected, the second connecting member 3 on the right side of one cathode wire body 1 and the first connecting member 2 on the left side of the other cathode wire body 1 overlap each other. The outer cylinder 34 at one end of 31 is fitted onto the outside of the internally threaded cylinder 23 of the lower connecting seat 21. At this time, a pair of moving blocks 35 on the inner wall of the outer cylinder 34 are located at the lowest end of the vertical groove 24. Through the cooperation of the rotating shaft 37, the second gear 38, the first gear 36 and the outer cylinder 34, when the rotating shaft 37 rotates, it drives the second gear 38 to rotate. Under the meshing action of the second gear 38 and the first gear 36, the outer cylinder 34 is rotated, so that the pair of moving blocks 35 rotate to the end of the horizontal groove 25 away from the vertical groove 24 under the action of the vertical groove 24. The outer cylinder 34 and the internally threaded cylinder 23 are connected, the upper connecting seat 31 and the lower connecting seat 21 are connected, and the second connecting piece 3 on the right side of the cathode wire body 1 and the first connecting piece 2 on the left side of the other cathode wire body 1 are connected, realizing the connection between a pair of cathode wire bodies 1. The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figures 1-5This utility model provides a technical solution: a hollow ring plate 39 is installed on the top surface of the dust cover 32 on the side away from the outer cylinder 34. The upper end of the rotating shaft 37 extends through the hollow ring plate 39 to the outside. Limiting seats 310 are connected to both sides of the top surface of the hollow ring plate 39. Slots 311 are opened inside the pair of limiting seats 310 and the rotating shaft 37. A rod 312 is provided between the three slots 311. The bottom surface of the outer cylinder 34 is in contact with the top surface of the lower connecting seat 21 at the end away from the cathode rod 11. The inner wall of the cylinder 34 is clearance-fitted with the outer wall of the internally threaded cylinder 23. The lower connecting seat 21 has a circular hole 22 inside at the end away from the cathode rod 11. The central axes of the circular hole 22, the internally threaded cylinder 23, and the outer cylinder 34 are collinear. Several serrated tips 12 are connected to the front and back of the pair of cathode rods 11. By setting a hollow ring plate 39, the inner wall of the hollow ring plate 39 is clearance-fitted with the outer wall of the rotating shaft 37, so as not to affect the rotation of the rotating shaft 37. Through the limiting seat 310, the slot 311, and the insertion rod 3 The use of connectors 12 and 311 allows the insertion rod 312 to engage with the slot 311, which can limit and fix the rotating shaft 37. When the first connector 2 and the second connector 3 are connected, inserting the insertion rod 312 can prevent the rotating shaft 37 from rotating freely. When the outer cylinder 34 inside the upper connecting seat 31 on the right side of one cathode wire body 1 is aligned with the internal threaded cylinder 23 inside the lower connecting seat 21 on the left side of another cathode wire body 1 and pressed down, the internal threaded cylinder 23 is located inside the outer cylinder 34, and the bottom surface of the outer cylinder 34 is lower than the connecting seat 21. The top surfaces of the ends away from the cathode rod 11 are attached together. At this time, the arc-shaped end of the upper connecting seat 31 and the arc-shaped end of the lower connecting seat 21 are attached to the inner wall of the arc-shaped groove of the lower connecting seat 21 and the inner wall of the arc-shaped groove of the upper connecting seat 31, respectively, so that the first connecting piece 2 and the second connecting piece 3 overlap each other. By the fact that the central axes of the round hole 22, the internal threaded cylinder 23 and the outer cylinder 34 are collinear, it is convenient for one end of the bolt fastener to pass through the round hole 22 and the internal threaded hole to rotate, and fix the connection of the pair of cathode rods 11 in the designated position.

[0028] Specifically, the working principle of this new type of wet electrostatic precipitator cathode wire is as follows: During use, when the outer cylinder 34 inside the upper connecting seat 31 on the right side of one cathode wire body 1 is aligned with the internally threaded cylinder 23 inside the lower connecting seat 21 on the left side of another cathode wire body 1 and pressed down, the internally threaded cylinder 23 is located inside the outer cylinder 34. The bottom surface of the outer cylinder 34 and the top surface of the lower connecting seat 21 at the end furthest from the cathode rod 11 are in contact. At this time, the arc-shaped end of the upper connecting seat 31 and the arc-shaped end of the lower connecting seat 21 are respectively aligned with the lower... The inner walls of the arc-shaped groove of the connecting seat 21 and the arc-shaped groove of the upper connecting seat 31 fit together, so that the first connecting piece 2 and the second connecting piece 3 overlap each other. Since the vertical groove 24 and the horizontal groove 25 are connected, at this time, a pair of moving blocks 35 on the inner wall of the outer cylinder 34 are located at the lowest end of the vertical groove 24. Through the cooperation of the rotating shaft 37, the second gear 38, the first gear 36 and the outer cylinder 34, when the rotating shaft 37 rotates, it drives the second gear 38 to rotate, and the second gear 38 and the first gear 36 mesh. The rotation of the outer cylinder 34 is achieved by changing the position of the moving block 35 inside the transverse groove 25. This causes the pair of moving blocks 35 to rotate to the end of the transverse groove 25 away from the vertical groove 24 under the action of the vertical groove 24. The outer cylinder 34 and the internal threaded cylinder 23 are connected, the upper connecting seat 31 and the lower connecting seat 21 are connected, and the second connecting piece 3 on the right side of the cathode wire body 1 and the first connecting piece 2 on the left side of the other cathode wire body 1 are connected, thus achieving the connection between a pair of cathode wire bodies 1. Through the cooperation of the limiting seat 310, the slot 311 and the insertion rod 312, the insertion rod 312 and the slot 311 can limit and fix the rotating shaft 37. When the first connecting piece 2 and the second connecting piece 3 are connected, inserting the insertion rod 312 can prevent the rotating shaft 37 from rotating arbitrarily. By the fact that the central axis of the round hole 22, the internal threaded cylinder 23 and the outer cylinder 34 are collinear, it is easy for one end of the bolt fastener to pass through the round hole 22 and the internal threaded hole and rotate, thus fixing the connection of a pair of cathode rods 11 in the designated position.
