Description

Technical Field

[0001] This invention belongs to the technical field of electrostatic precipitator equipment, specifically, it relates to a simple electrostatic precipitator for sulfuric acid process rutile titanium dioxide. Background Technology

[0002] The production process of rutile titanium dioxide using the sulfuric acid process generates a large amount of waste gas containing pollutants such as acid mist. If this waste gas is discharged directly into the atmosphere without effective treatment, it will cause serious air pollution, trigger environmental problems such as acid rain, and pose a threat to the ecological environment and human health. Therefore, it is crucial to effectively purify the waste gas generated during the production of rutile titanium dioxide using the sulfuric acid process. Currently, there are various related devices and technologies for waste gas purification, especially electrostatic precipitators.

[0003] Traditional electrostatic precipitators have a relatively fixed ionization area, with the barbs on the cathode wire remaining at a constant position. This results in a limited ionization area, and during waste gas treatment, as particulate matter in the waste gas continuously adheres to the surface of the cathode wire, the ionization efficiency gradually decreases, leading to poor charging of acid mist particles. This, in turn, affects the quality of waste gas purification, making it difficult to meet increasingly stringent environmental emission standards. Furthermore, the flow path of waste gas within traditional electrostatic precipitators is short, and the residence time is limited. This results in insufficient contact between particulate matter in the waste gas and the ionization area, leading to a low charging efficiency and an inability to fully remove pollutants from the waste gas, resulting in unsatisfactory purification effects. To address this, we propose a simplified electrostatic precipitator for rutile titanium dioxide produced using the sulfuric acid process. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0005] A simple electrostatic precipitator for rutile titanium dioxide produced by the sulfuric acid process includes an air vent, a wire, and a rigid tubular cathode wire. The air vent includes an outer cylinder and an inner cylinder, with the inner cylinder located inside the outer cylinder. A gas guide hood is fitted around the outer side of the inner cylinder. A fixing block is fixedly fitted onto the outer wall of the wire. An L-shaped fixing plate connects the outer wall of the fixing block to the top of the gas guide hood. The rigid tubular cathode wire is rotatably connected to the bottom end of the fixing block. The rigid tubular cathode wire moves through the top of the gas guide hood and passes through the inner cylinder. A counterweight is rotatably connected to the bottom end of the rigid tubular cathode wire. An anode cylinder I is attached to the inner wall of the inner cylinder. Anode cylinder II is provided on all four sides of the outer wall of the inner cylinder. A disassembly and assembly assembly for fixing anode cylinder I and anode cylinder II is provided between the anode cylinder I, anode cylinder II, and the inner cylinder. A slow-flow rotation mechanism is provided on the rigid tubular cathode wire. A connecting plate is installed at the top of the inner wall of the gas guide hood. A rigid plate cathode wire is installed on the outer wall of the connecting plate and inserted into the anode cylinder II.

[0006] The slow-flow rotation mechanism includes a guide cylinder and a guide frame. The guide cylinder is installed on a rigid tubular cathode wire, and the guide frame is located below the guide cylinder. A connecting ring is rotatably sleeved on the outer wall of the rigid tubular cathode wire. A fixing rod is connected between the connecting ring and the inner wall of the top outlet of the guide frame. A turbine blade is installed at the bottom end of the guide cylinder.

[0007] In a preferred embodiment of the present invention, a limiting ring plate is installed on the inner wall of the connecting ring, and a limiting ring groove is formed on the outer wall of the rigid tubular cathode wire. The limiting ring plate and the limiting ring groove are rotatably connected. There are four sets of slow-flow rotation mechanisms, and the guide frames on the four sets of slow-flow rotation mechanisms are connected by connecting rods. By setting the limiting ring plate and the limiting ring groove, the connecting ring can be limited, so that the connecting ring and the rigid tubular cathode wire can be relatively fixed and rotated.

[0008] In a preferred embodiment of the present invention, an I-shaped block is installed at the bottom of the fixing block, and a connecting block is installed at the top of the rigid tubular cathode wire. The connecting block is rotatably connected to the outer wall of the I-shaped block. By setting the I-shaped block and the connecting block, the rigid tubular cathode wire can be fixed and rotated below the fixing block.

[0009] In a preferred embodiment of the present invention, a connecting plate is installed at the bottom end of the rigid tubular cathode wire, a T-shaped rotating block is installed at the bottom end of the connecting plate, and a T-shaped rotating groove is opened at the top end of the counterweight block. The T-shaped rotating block and the T-shaped rotating groove are rotatably connected. By setting the T-shaped rotating block and the T-shaped rotating groove, the counterweight block and the rigid tubular cathode wire can achieve relative rotation, reducing the impact of the counterweight block on the rigid tubular cathode wire and ensuring the flexibility of the rotation of the rigid tubular cathode wire.

[0010] In a preferred embodiment of the present invention, the rigid tubular cathode wire is provided with a reinforcing rib inside. The reinforcing rib is installed between the connecting plate and the connecting block. The guide cylinder is fixedly connected to the reinforcing rib through the outer wall of the rigid tubular cathode wire. The outer wall of the guide frame near the bottom end is attached to the inner wall of the anode cylinder. By providing the reinforcing rib, the rigid tubular cathode wire can be reinforced to a certain extent, thereby improving the service strength of the rigid tubular cathode wire. The reinforcing rib can be made of alloy steel.

[0011] In a preferred embodiment of the present invention, the inner wall of the gas guide shroud is provided with an installation groove, the anode cylinder II is engaged in the installation groove, the connecting plate is provided with a connecting hole, the inner wall of the connecting hole is provided with a limiting ring groove II, the outer wall of the rigid tubular cathode wire is fixedly sleeved with a limiting ring plate II, the limiting ring plate II is rotatably connected to the limiting ring groove II, and a connecting column is connected between the top of the connecting plate and the gas guide shroud. By setting the limiting ring plate II and the limiting ring groove II, the rigid tubular cathode wire and the connecting plate can be rotated relative to each other, and the rigid plate cathode wire can be electrically connected to the rigid tubular cathode wire through the limiting ring plate II and the connecting plate.

[0012] In a preferred embodiment of the present invention, a sealing frame is fixedly fitted on the outer wall of the rigid tubular cathode wire, and a sealing groove is opened at the top of the inner wall of the gas guide hood. The sealing frame is inserted into the sealing groove and is rotatably connected to the sealing groove. A sealing ring is installed on the inner wall of the sealing groove, and the sealing ring is tightly fitted to the outer wall surface of the sealing frame. There is a gap between the gas guide hood and the bottom of the inner wall of the outer cylinder. By setting the sealing frame, sealing groove and sealing ring, the sealing performance between the rigid tubular cathode wire and the gas guide hood can be greatly improved, and exhaust gas leakage can be avoided.

[0013] In a preferred embodiment of the present invention, the fixing block, the I-shaped block, the connecting block, the limiting ring plate II, and the connecting disk are all made of conductive materials, and the outer wall of the rigid tubular cathode wire is provided with barbs.

[0014] In a preferred embodiment of the present invention, the disassembly and assembly assembly includes a first clamping plate, a second clamping plate, and an L-shaped limiting plate. The first clamping plate is slidably connected to the top end of the first anode cylinder and is clamped to the top end of the inner cylinder. The second clamping plate is installed on the top end of the second anode cylinder. A clamping groove is provided on one side of the first clamping plate, and the second clamping plate is inserted into the groove. The L-shaped limiting plate is slidably connected to the top end of the inner cylinder. A limiting groove is provided on the outer walls of the first and second clamping plates, and the L-shaped limiting plate is inserted into the limiting groove. By setting the L-shaped limiting plate, the first and second clamping plates can be inserted into the limiting groove, thereby limiting the position of the first clamping plate and the second clamping plate, and thus fixing the first and second anode cylinders.

[0015] In a preferred embodiment of the present invention, a T-shaped sliding plate is installed at the top of the inner cylinder, and a T-shaped sliding groove is formed at the bottom of the card plate. The T-shaped sliding plate and the T-shaped sliding groove are slidably connected. A movable groove is formed at the top of the inner cylinder, and an L-shaped limiting plate is slidably connected to the movable groove. A limiting rod is fixedly installed on the inner wall of the movable groove. The limiting rod movably passes through the L-shaped limiting plate, and a spring is surrounded on the outer wall of the limiting rod. The spring is installed between the outer wall of the L-shaped limiting plate and the inner wall of the movable groove. By setting the limiting rod, the L-shaped limiting plate and the spring can be limited, ensuring the stability of the L-shaped limiting plate and the spring during use and compression.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention allows the rigid tubular cathode wire to rotate as the exhaust gas passes through the ventilation cylinder. This causes the position of the barbs on the rigid tubular cathode wire to change periodically, dynamically refreshing the ionization region. Under the action of centrifugal force, it can effectively reduce the adhesion of dust to its surface, expand the effective ionization area, and thus improve the charging efficiency of acid mist particles. Furthermore, the guide frame and guide cylinder can increase the flow time of the exhaust gas in the anode cylinder, thereby increasing the probability of particles in the exhaust gas becoming charged. This causes the charged particles to be adsorbed onto the inner wall of the anode cylinder, thus greatly improving the quality of exhaust gas purification.

[0018] This invention, through the combined action of the gas guide hood, the second anode cylinder, and the rigid plate cathode wire, can guide the waste gas into the second anode cylinder, causing the residual particles in the waste gas to become charged, thereby achieving secondary purification of the waste gas and further improving the quality of waste gas purification.

[0019] This invention, by setting up modular anode cylinder one and anode cylinder two, facilitates disassembly and replacement by personnel, eliminating the need to wait for cleaning before subsequent purification, thus greatly saving time and ensuring improved efficiency in waste gas treatment.

[0020] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

The following embodiments are used to illustrate the present invention.

[0034] like Figures 1 to 10As shown, the present invention provides a technical solution: a simple electrostatic precipitator for rutile titanium dioxide produced by the sulfuric acid process, comprising an air vent, a wire 3, and a rigid tubular cathode wire 9. The air vent includes an outer cylinder 1 and an inner cylinder 2, with the inner cylinder 2 disposed inside the outer cylinder 1. A gas guide hood 5 is fitted over the outer side of the inner cylinder 2. A fixing block 4 is fixedly fitted over the outer wall of the wire 3.

The outer wall of the connecting plate 41 is equipped with a rigid plate cathode wire 40. The rigid plate cathode wire 40 is inserted into the anode cylinder 22.

[0035] The slow-flow rotation mechanism includes a guide cylinder 15 and a guide frame 17. The guide cylinder 15 is installed on the rigid tubular cathode wire 9, and the guide frame 17 is located below the guide cylinder 15. A connecting ring 18 is rotatably sleeved on the outer wall of the rigid tubular cathode wire 9. A fixing rod 43 is connected between the connecting ring 18 and the inner wall of the top outlet of the guide frame 17. A turbine blade 16 is installed at the bottom of the guide cylinder 15.

[0036] Furthermore, a limiting ring plate 19 is installed on the inner wall of the connecting ring 18, and a limiting ring groove 20 is opened on the outer wall of the rigid tubular cathode wire 9. The limiting ring plate 19 and the limiting ring groove 20 are rotatably connected. There are four sets of slow-flow rotation mechanisms, and the guide frames 17 on the four sets of slow-flow rotation mechanisms are connected by connecting rods 39.

[0037] The limiting ring plate 19 and the limiting ring groove 20 can limit the connecting ring 18, so that the connecting ring 18 and the rigid tubular cathode wire 9 can be relatively fixed and rotated.

[0038] Furthermore, an I-shaped block 7 is installed at the bottom of the fixing block 4, and a connecting block 8 is installed at the top of the rigid tubular cathode wire 9. The connecting block 8 is rotatably connected to the outer wall of the I-shaped block 7.

[0039] By setting the I-shaped block 7 and the connecting block 8, the rigid tubular cathode wire 9 can be fixed and rotated below the fixed block.

[0040] Furthermore, a connecting plate 11 is installed at the bottom of the rigid tubular cathode wire 9, a T-shaped rotating block 13 is installed at the bottom of the connecting plate 11, and a T-shaped rotating groove 14 is opened at the top of the counterweight block 12. The T-shaped rotating block 13 and the T-shaped rotating groove 14 are rotatably connected.

[0041] By setting T-shaped rotating block 13 and T-shaped rotating groove 14, the counterweight block 12 and the rigid tubular cathode wire 9 can rotate relative to each other, reducing the impact of the counterweight block 12 on the rigid tubular cathode wire 9 and ensuring the flexibility of the rigid tubular cathode wire 9 in rotation.

[0042] Furthermore, the rigid tubular cathode wire 9 is provided with a reinforcing rib 10 inside. The reinforcing rib 10 is installed between the connecting plate 11 and the connecting block 8. The guide cylinder 15 is fixedly connected to the reinforcing rib 10 through the outer wall of the rigid tubular cathode wire 9. The guide frame 17 is close to the bottom outer wall and fits against the inner wall of the anode cylinder 21.

[0043] Among them, by setting the reinforcing rib 10, the rigid tubular cathode wire 9 can be reinforced to a certain extent, and the service strength of the rigid tubular cathode wire 9 can be improved. The material of the reinforcing rib 10 can be alloy steel.

[0044] Furthermore, the inner wall of the gas guide shroud 5 is provided with an installation groove 33, the anode cylinder 22 is engaged in the installation groove 33, the connecting plate 41 is provided with a connecting hole, the inner wall of the connecting hole is provided with a limiting ring groove 38, the outer wall of the rigid tubular cathode wire 9 is fixedly sleeved with a limiting ring plate 37, the limiting ring plate 37 is rotatably connected to the limiting ring groove 38, and a connecting column 42 is connected between the top of the connecting plate 41 and the gas guide shroud 5.

[0045] By setting the limiting ring plate 2 37 and the limiting ring groove 2 38, the rigid tubular cathode wire 9 and the connecting disk 41 can rotate relative to each other, and the rigid plate cathode wire 40 can be electrically connected to the rigid tubular cathode wire 9 through the limiting ring plate 2 37 and the connecting disk 41.

[0046] Furthermore, a sealing frame 34 is fixedly sleeved on the outer wall of the rigid tubular cathode wire 9, and a sealing groove 35 is opened at the top of the inner wall of the gas guide hood 5. The sealing frame 34 is inserted into the sealing groove 35 and is rotatably connected with the sealing groove 35. A sealing ring 36 is installed on the inner wall of the sealing groove 35. The sealing ring 36 is tightly fitted with the outer wall surface of the sealing frame 34. There is a gap between the gas guide hood 5 and the bottom of the inner wall of the outer cylinder 1.

[0047] By setting the sealing frame 34, sealing groove 35 and sealing ring 36, the sealing performance between the rigid tubular cathode wire 9 and the gas guide shroud 5 can be greatly improved, thus preventing exhaust gas leakage.

[0048] Furthermore, the fixing block 4, the I-shaped block 7, the connecting block 8, the limiting ring plate 37, and the connecting plate 41 are all made of conductive materials, and the outer wall of the rigid tubular cathode wire 9 is provided with barbs.

[0049] Furthermore, the assembly and disassembly components include a first clamping plate 23, a second clamping plate 27, and an L-shaped limiting plate 26. The first clamping plate 23 is slidably connected to the top of the anode cylinder 21, and the first clamping plate 23 is clamped to the top of the inner cylinder 2. The second clamping plate 27 is installed on the top of the anode cylinder 22. A groove 28 is provided on one side of the first clamping plate 23, and the second clamping plate 27 is inserted into the groove 28. The L-shaped limiting plate 26 is slidably connected to the top of the inner cylinder 2. A limiting groove 29 is provided on the outer wall of the first clamping plate 23 and the second clamping plate 27, and the L-shaped limiting plate 26 is inserted into the limiting groove 29.

[0050] In this design, by setting an L-shaped limiting plate 26, the L-shaped limiting plate 26 can be inserted into the limiting groove 29, thereby limiting the first clamping plate 23 and the second clamping plate 27, and thus fixing the first anode cylinder 21 and the second anode cylinder 22.

[0051] Furthermore, a T-shaped sliding plate 24 is installed at the top of the inner cylinder 2, and a T-shaped sliding groove 25 is opened at the bottom of the first card plate 23. The T-shaped sliding plate 24 and the T-shaped sliding groove 25 are slidably connected. A moving groove 30 is opened at the top of the inner cylinder 2. An L-shaped limiting plate 26 is slidably connected to the moving groove 30. A limiting rod 31 is fixedly installed on the inner wall of the moving groove 30. The limiting rod 31 moves through the L-shaped limiting plate 26. A spring 32 surrounds the outer wall of the limiting rod 31. The spring 32 is installed between the outer wall of the L-shaped limiting plate 26 and the inner wall of the moving groove 30.

[0052] The limiting rod 31 can limit the L-shaped limiting plate 26 and the spring 32, ensuring the stability of the L-shaped limiting plate 26 and the spring 32 during compression.

[0053] The implementation principle of a simple electrostatic precipitator for rutile titanium dioxide produced by the sulfuric acid process is as follows: In use, multiple sets of this device are arranged in a honeycomb pattern inside the waste gas treatment tower. Then, the rigid tubular cathode wire 9, anode cylinder 1 21, and anode cylinder 22 are energized, creating magnetic fields between the rigid tubular cathode wire 9 and anode cylinder 1 21, and between the rigid plate cathode wire 40 and anode cylinder 22. At this time, the waste gas enters the anode cylinder 1 21 through the bottom of the inner cylinder 2. After being guided by the guide frame 17, the waste gas is blown towards the guide cylinder 15, and then continues to move upwards after being guided by the guide cylinder 15. The turbine blades 16, under the action of the airflow, drive the guide cylinder 15 to rotate, which in turn drives the rigid tubular cathode wire 9 to rotate. This causes the position of the barbs on the rigid tubular cathode wire 9 to change periodically, dynamically refreshing the ionization area. Furthermore, under the action of centrifugal force, it can effectively reduce... Dust adheres to its surface, expanding the effective ionization area and thus improving the charging efficiency of acid mist particles. Furthermore, the guide frame 17 and guide cylinder 15 increase the flow time of the exhaust gas in the anode cylinder 21, thereby increasing the probability of particles in the exhaust gas becoming charged. This causes the charged particles to adhere to the inner wall of the anode cylinder 21, significantly improving the quality of exhaust gas purification. After initial purification through the inner cylinder 2, the exhaust gas flows into the anode cylinder 22 under the action of the air guide shroud 5, where it undergoes secondary purification. This charges the remaining particles in the initially purified exhaust gas, which then adhere to the anode cylinder 22. Through the combined action of the air guide shroud 5, the anode cylinder 22, and the rigid plate cathode wire 40, the exhaust gas is guided into the anode cylinder 22, causing the remaining particles to become charged. This achieves secondary purification of the exhaust gas, further improving the quality of exhaust gas purification.When cleaning and replacing anode cylinder 1 21 and anode cylinder 22 are required, the wire 3 can be directly disassembled upwards. The wire 3, through the L-shaped fixing plate 6 and the fixing block 4, will drive the air guide hood 5 and the rigid tubular cathode wire 9 upwards, causing the air guide hood 5 to detach from the ventilator. This will also cause the rigid tubular cathode wire 9, the rigid plate cathode wire 40, the guide frame 17, and the guide cylinder 15 to detach from the ventilator. Then, the L-shaped limiting plate 26 can be pulled outwards, compressing the spring 32 and disengaging it from the limiting groove 29. This will prevent the L-shaped limiting plate 26 from limiting the clamping plates 1 23 and 27. Finally, pulling anode cylinder 22 outwards will cause it to disengage clamping plate 27 from the clamping groove. 28. Disconnect anode cylinder 22 from the outer wall of inner cylinder 2, thus completing the disassembly of anode cylinder 22. Then, pull anode cylinder 21 upwards to disconnect it from inner cylinder 2, thus completing the disassembly of anode cylinder 21. At this point, anode cylinders 21 and 22 can be directly cleaned and maintained. New anode cylinders 21 and 22 can then be installed to ensure proper purification of subsequent waste gas. The modular design of anode cylinders 21 and 22 facilitates disassembly and replacement, eliminating the need to wait for cleaning before subsequent purification, significantly saving time and improving the efficiency of the device in treating waste gas.
