Description

Technical Field

[0001] This utility model relates to the technical field of converter dust removal, specifically a cooling converter electrostatic precipitator. Background Technology

[0002] The converter is one of the most important pieces of equipment in the steelmaking process, especially in steel production. It reacts molten iron with oxygen to remove impurities and produce molten steel. In this process, a large amount of dust, flue gas and harmful substances are generated. If not treated, these substances may harm the environment and the health of workers. Therefore, dust collectors are needed to treat these substances. However, existing converter dust collectors still have certain defects in their use. During use, the dust removal system of existing converter dust collectors is unstable, and ash blockage and explosion failures often occur. Flue gas overflow pollution still exists in the converter production process.

[0003] To overcome the aforementioned deficiencies, prior art 1 (Chinese patent application number 201921606163.9, application date 2019-09-25) describes a wet electrostatic precipitator for converters, belonging to the field of metallurgical dust removal equipment. This electrostatic precipitator includes a shell, with a gas outlet at the top and a gas inlet at the bottom. Inside the shell, from top to bottom, are arranged a cyclone separator, a spray device, cathode wires, an anode plate, and a gas flow equalization device. The cyclone separator, spray device, and cathode wires are spaced apart, and the gas flow equalization device is spaced below the lower end face of the anode plate and above the gas inlet. A drain outlet is located at the bottom of the shell. This electrostatic precipitator, as an integrated device for gas cooling, dust removal, and dehydration, can achieve the goal of flue gas dust concentration emissions below ultra-clean emission levels and can replace gas coolers and dehydrators, thus solving the problem of system complexity.

[0004] While existing technologies can improve the overall structural stability, during operation, the dust collector uses a spray device for cooling and dust removal, which not only consumes a large amount of water, increasing water resource consumption, but also easily leads to clogging and corrosion of components due to the influence of particles and moisture in the dust-laden gas. The spray device and water pipe system require regular maintenance and cleaning, increasing maintenance costs. Clogging of the spray device can easily affect the dust removal efficiency of the equipment.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing cooling-type converter electrostatic precipitator. Therefore, we proposed that the cooling-type converter electrostatic precipitator can effectively solve the above problems. Utility Model Content

Currently, dust collectors on the market use spray devices for cooling and dust removal, which not only consume a large amount of water, increasing water resource consumption, but also easily lead to component blockage and corrosion due to the influence of particles and moisture in the dust-laden gas. The spray device and water pipe system require regular maintenance and cleaning, increasing maintenance costs. Furthermore, the blockage of the spray device can easily affect the dust removal efficiency of the equipment.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This cooling converter electrostatic precipitator uses a corona discharge stage inside the precipitator body to adsorb dust from the flue gas onto the dust collection plate. This achieves highly efficient separation of flue gas and dust, resulting in high dust removal efficiency, effective purification of flue gas, and reduced environmental pollution. The dust is also shaken off from the dust collection plate, reducing resource waste and increased costs associated with spray dust removal. Overall, the system operates stably, minimizing the need for frequent maintenance that could reduce dust removal efficiency. The specific details are as follows:

[0016] (1) The corona discharge inside the dust collector body can efficiently separate flue gas and dust, effectively purify flue gas, reduce the pollution of flue gas to the environment, shake off the dust on the dust collection plate, and reduce the waste of resources and increased costs caused by using spray dust removal.

[0017] (2) The second motor drives the positive and negative screws to rotate, and drives the agitator to rotate inside the mixing box through the drive component, which facilitates the uniform mixing of dust and auxiliary materials, ensuring the stable quality of the pellets produced later, and providing high-quality iron-containing materials for the converter.

The groove on the pressure roller forms the mixture into pellets, which makes it convenient to use the pellets as iron-containing materials for the converter. This not only realizes the secondary utilization of solid waste and the recycling of resources, but also reduces pollutant emissions, stabilizes the converter operation, and reduces the cost of solid waste treatment.

[0019] (4) The second moving block is raised and lowered in cooperation with the second guide rod, which not only enables the conveying cylinder to be used, but also reduces the problem of increased cost caused by setting more drive structures, improves the energy utilization efficiency of the equipment, and reduces the cost of the equipment.

Excess liquid inside the temperature regulating cover flows back into the liquid storage tank, improving the utilization rate of resources. Attached Figure Description

[0029] 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.

[0030] Example 1: In this example, the dust on the dust collection plate 5 is shaken off, reducing the resource waste and increased costs associated with using spray dust removal. Overall operation is stable, reducing the need for frequent maintenance that could lead to reduced dust removal efficiency. Figures 1-5The technical solution shown includes a dust collector body 1, a gas inlet pipe 2 on the side of the dust collector body 1, a dust collection assembly inside the dust collector body 1, a corona electrode 4 installed inside the dust collector body 1, the corona electrode 4 being electrically connected to a power transmission component 3 located at the top of the dust collector body 1, a dust collection plate 5 installed inside the dust collector body 1, an auxiliary assembly on the upper end of the dust collection plate 5, and a support frame 6 installed on the upper end of the support frame 5. The inner side of the support frame 6 is oscillated by shaking. Component 7 is connected to the side of the dust collection plate 5. A connecting plate 8 is provided on the upper end of the support frame 6. A first moving block 9 is installed on the upper end of the connecting plate 8. A first guide rod 10 is connected through the first moving block 9. A spring 11 is sleeved on the outside of the first guide rod 10. A first motor 12 is installed on the side of the dust collector body 1. The output end of the first motor 12 is connected to an eccentric wheel 14 through a rotating shaft 13. The eccentric wheel 14 is located on the side of the connecting plate 8, and after the eccentric wheel 14 rotates, it contacts the connecting plate 8. The flue gas to be treated is discharged through the gas inlet pipe 2. The gas is delivered into the dust collector body 1. The power supply component 3 is turned on, causing the corona electrode 4 inside the dust collector body 1 to discharge. At this time, the dust inside the flue gas is adsorbed onto the dust collection plate 5, which can efficiently separate the flue gas and dust. The dust removal efficiency is high, which can effectively purify the flue gas and reduce the pollution of the environment. The first motor 12 is turned on, and the output end of the first motor 12 drives the eccentric wheel 14 to rotate through the rotating shaft 13. The eccentric wheel 14 contacts the connecting plate 8, causing the connecting plate 8 to move on the first guide rod 10 through the first moving block 9. This causes the shaking component 7 in the support frame 6 under the connecting plate 8 to shake off the dust on the dust collection plate 5, reducing the waste of resources and increased costs caused by using spray dust removal. The overall operation is stable, reducing the need for frequent maintenance and the problem of reduced dust removal efficiency. Since the first guide rod 10 is equipped with a spring 11, when the eccentric wheel 14 continues to rotate away from the surface of the connecting plate 8, the spring 11 rebounds, which makes it easy for the connecting plate 8 to return to its initial position. The overall automation level is greatly improved.

[0031] Example 2: In this example, the slot 24 forms the mixture into pellets, facilitating the use of these pellets as iron-containing materials in the converter. This not only achieves secondary utilization of solid waste and resource recycling but also stabilizes converter operation and reduces solid waste treatment costs. Specifically, as follows... Figure 2 and Figure 6As shown, the bottom of the dust collector body 1 is connected to a mixing box 16 via a dust collection hopper 15. A drive box 17 is located on the side of the mixing box 16. A drive assembly is installed inside the drive box 17, including a second motor 18 installed inside the drive box 17. The output end of the second motor 18 is connected to a positive and negative screw 19. The upper end of the positive and negative screw 19 is connected to a rotating shaft 20 via a drive component. The upper end of the rotating shaft 20 is connected to a stirring component 21 via a drive component. The stirring component 21 is installed inside the mixing box 16. A cold press 22 is located at the bottom of the mixing box 16. Pressure rollers 23 are installed inside the cold press 22. The pressure rollers 23 are symmetrically arranged and have slots 24. Falling dust enters the mixing box 16 through the dust collection hopper 15. Auxiliary materials are poured into the mixing box 16. The drive box 17 is then opened. The second motor 18 drives the positive and negative screws 19 to rotate, which in turn drives the rotating shaft 20 through the drive component. This allows the rotating shaft 20 to drive the agitator 21 to rotate inside the mixing box 16, facilitating the uniform mixing of dust and auxiliary materials. This ensures the stable quality of the subsequently produced pellets and provides high-quality iron-containing materials for the converter. The mixture falls into the cold pressing box 22. The drive motor on the side of the cold pressing box 22 is turned on, causing the pressure roller 23 to rotate. The groove 24 on the pressure roller 23 forms the mixture into pellets, which can then be used as iron-containing materials for the converter. This not only realizes the secondary utilization of solid waste and the recycling of resources, reducing pollutant emissions, but also stabilizes the converter operation and reduces solid waste treatment costs.

[0032] Example 3: In this example, by effectively regulating the temperature of the power transmission component 3, the stable operation of the dust collector body 1 is ensured, reducing equipment failures and maintenance frequency. Specifically, as follows... Figure 2 , Figure 6 and Figure 7As shown, a second movable block 25 is provided on the outer side of the positive and negative screw 19. A second guide rod 26 is connected through the second movable block 25. A piston 27 is connected to the side end of the second movable block 25. The piston 27 is located inside the conveying cylinder 28. The input end of the conveying cylinder 28 is connected to the inside of the liquid storage tank 29 through a pipe. The liquid storage tank 29 is located at the bottom of the drive box 17. The output end of the conveying cylinder 28 is connected to the inside of the temperature regulating cover 30 through a pipe. The temperature regulating cover 30 is sleeved on the outside of the power transmission component 3. When the positive and negative screw 19 rotates, the second movable block 25 on its outer side moves up and down in cooperation with the second guide rod 26, so that the piston 27 inside the conveying cylinder 28 moves up and down through the second movable block 25, which not only enables the conveying cylinder 28 to be used, but also... Furthermore, it reduces the need for numerous drive structures, thus minimizing costs and improving energy efficiency. The conveying cylinder 28 transports the liquid from the storage tank 29 to the temperature regulating hood 30, which effectively regulates the temperature of the power transmission component 3, significantly extending its lifespan. Excess liquid in the temperature regulating hood 30 flows back to the storage tank 29 and is effectively regulated by the temperature control device inside the storage tank 29, improving resource utilization. Effective temperature regulation of the power transmission component 3 ensures stable operation of the dust collector body 1, reducing equipment failures and maintenance frequency.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
