Description

Technical Field

[0001] This application relates to the field of dust removal, and more particularly to a dust removal device and dust removal system. Background Technology

[0002] High-humidity, high-sulfur waste gas generated in industrial production presents a significant challenge in waste gas treatment due to its complex characteristics, including high concentrations of sulfuric acid mist (acidic aerosol), high particulate matter content, and high moisture content. Conventional waste gas treatment equipment is severely ineffective at removing these complex pollutants, making it difficult to ensure compliance with emission standards. While existing filtration-based dust removal technologies can effectively capture solid particulate matter, they are inefficient at removing highly corrosive sulfuric acid mist, which exists in aerosol form. Acidic mist not only has strong penetrability and is easily escaped, but its high corrosiveness also accelerates equipment damage and significantly shortens equipment lifespan. Utility Model Content

[0043] This application provides a dust removal device, which includes a first cylinder 100, a second cylinder 200, a mounting bracket 400, a discharge electrode 500, and a dust collection electrode 600.

[0044] In some specific embodiments, the first cylinder 100 is connected to an air inlet pipe 110, a portion of which extends into the first cylinder 100. Each air inlet pipe 110 has an air outlet, the outlet being opposite to the exhaust gas emission direction. The second cylinder 200 is located on one side of the first cylinder 100 along the exhaust gas emission direction. Multiple insulating components 300 are fixedly installed on the circumferential surfaces of both the first cylinder 100 and the second cylinder 200. A mounting bracket 400 is installed at the position of the first cylinder 100 and the second cylinder 200. On the insulating component 300 at the position of the cylinder 200, the two ends of the discharge electrode 500 are respectively mounted on the mounting bracket 400 at the positions of the first cylinder 100 and the second cylinder 200. One end of the dust collecting electrode 600 is connected to the first cylinder 100, and the end of the dust collecting electrode 600 away from the first cylinder 100 is connected to the second cylinder 200. The first cylinder 100, the second cylinder 200 and the dust collecting electrode 600 define a gas cavity. The discharge electrode 500 is located in the gas cavity, and the insulating component 300 communicates with the gas cavity.

[0045] The exhaust gas is discharged from bottom to top, that is, the second cylinder 200 is located above the first cylinder 100, and the dust collection electrode 600 is located between the first cylinder 100 and the second cylinder 200.

[0046] Please see Figure 1As shown, the discharge electrode 500 is a conductive wire, that is, the discharge electrode 500 is a cathode wire, and this wire is connected to an external power source. The external power source directly supplies power to the discharge electrode 500. The dust collecting electrode 600 is tubular and hollow inside, and is an anode tube. In this embodiment, the exhaust gas enters the first cylinder 100 from the bottom inlet pipe 110, then flows upward through the gas chamber and finally exits to the outside from the exhaust pipe 210 of the second cylinder 200. During this process, the gas located in the dust collecting electrode 600 is ionized under the action of high voltage. At this time, the gas... Dust particles and droplets carrying negative charges move towards the dust collecting electrode 600 under the influence of the electric field between the discharge electrode 500 and the dust collecting electrode 600, and are collected by the dust collecting electrode 600. The inner wall of the dust collecting electrode 600 has a water film (formed by spraying water). Dust particles and droplets fall down along the inner wall of the dust collecting electrode 600 under the action of gravity. Water can also be sprayed onto the dust collecting electrode 600 to wash away the dust particles and droplets on the inner wall of the dust collecting electrode 600, causing them to fall into the first cylinder 100 for collection.

[0047] It is understandable that some sulfuric acid gases are soluble in water, so the acidic gases will dissolve in highly humid water mist to form acid mist, and dust particles will also combine with mist droplets. Under the action of an electric field, the dust particles bound to mist droplets can be removed, thus having a certain effect on removing acidic gases.

[0048] Please continue reading. Figure 1 As shown, in order to ensure that the exhaust gas from the intake pipe 110 is evenly distributed in the first cylinder 100, the intake pipe 110 is partially inserted into the first cylinder 100. Since dust particles and droplets fall from top to bottom, in order to prevent dust particles and droplets from entering the intake pipe 110, the outlet of the intake pipe 110 can be oriented downwards. This can prevent dust particles and other particles from entering the intake pipe 110 and also increase the diffusion time of the exhaust gas in the first cylinder 100, so that the exhaust gas can be evenly distributed in the first cylinder 100.

[0049] In this embodiment, since the exhaust gas is highly acidic, it is very easy to cause corrosion to various components over a long period of time. Therefore, the components that come into direct contact with the exhaust gas in this application should be made of corrosion-resistant materials, such as stainless steel.

[0050] In some specific embodiments, the insulating component 300 includes a housing 310, the housing 310 having a mounting cavity 311, an insulating component 320 being fixedly disposed within the mounting cavity 311, and the insulating component 320 being connected to the mounting bracket 400.

[0051] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, in order to fix the two mounting brackets 400 in the first cylinder 100 and the second cylinder 200 respectively for mounting the discharge electrode 500, insulating components 300 are provided on both sides of the outer periphery of the first cylinder 100 and on both sides of the outer periphery of the second cylinder 200. Since the second cylinder 200 is located above the first cylinder 100, the insulating component 300 at the position of the second cylinder 200 can be defined as the top insulating component 300, and the insulating component 300 at the position of the first cylinder 100 can be defined as the bottom insulating component 300. The insulating component 300 at each position has the same structure and is connected to the air cavity.

[0052] In this embodiment, a mounting bracket 400 that radially penetrates the first cylinder 100 is connected between the two bottom insulating components 300, and a mounting bracket 400 that radially penetrates the second cylinder 200 is connected between the two top insulating components 300, and the two mounting brackets 400 have the same structure.

[0053] Please see Figure 4 and Figure 5 As shown, since both mounting brackets 400 are connected to the discharge electrode 500, the mounting brackets 400 are also charged. In order to prevent the mounting brackets 400 from directly contacting the housing 310 and causing a short circuit, an insulating member 320 is fixedly installed in each housing 310, and the mounting brackets 400 are fixedly installed on the insulating member 320, thereby achieving insulation between the mounting brackets 400 and the housing 310.

[0054] For example, the insulating element 320 can be an insulating component such as a ceramic insulator.

[0055] In some specific embodiments, the dust collecting electrode 600 includes multiple tubes 610 and multiple reinforcing hoops 620. The tubes 610 are fixedly connected to each other. The tube group composed of multiple tubes 610 has multiple reinforcing hoops 620 located in its axial direction along the length direction of the tube group. One end of the tube group is provided with a first connector 630 connected to the first cylinder 100, and the other end of the tube group away from the first connector 630 is provided with a second connector 640 connected to the second cylinder 200.

[0056] Please see Figure 2As shown, in this embodiment, the entire pipe assembly is composed of multiple pipe bodies 610. Specifically, the pipe bodies 610 can be connected by welding. In order to connect with the first cylinder 100 and the second cylinder 200, the bottom of each pipe body 610 is fixedly connected to the first connector 630, and the top of each pipe body 610 is fixedly connected to the second connector 640. The connection between the pipe body 610 and the first connector 630 is sealed to prevent exhaust gas from escaping from the gaps between the pipe bodies 610 and the gap between the pipe body 610 and the first connector 630. Similarly, the connection between the pipe body 610 and the second connector 640 is also sealed to prevent exhaust gas from escaping from the connection between the pipe body 610 and the second connector 640. Furthermore, the connection between the first connector 630 and the first cylinder 100 and the connection between the second connector 640 and the second cylinder 200 are also sealed to prevent gas leakage.

[0057] Furthermore, in order to ensure that the various first connectors 630 are firmly connected and do not become separated, a reinforcing hoop 620 is fixedly installed on the periphery of the pipe assembly composed of the various first connectors 630 to achieve reinforcement.

[0058] For example, the first connector 630 and the second connector 640 may be connecting flanges.

[0059] In some specific embodiments, the cross-section of the tube 610 is polygonal, and the number of sides of the polygon is N, satisfying: N≥3.

[0060] For example, the cross-section of the tube 610 can be triangular, quadrilateral, pentagonal, hexagonal, heptagonal, etc. In this embodiment, the cross-section of the tube 610 is a regular hexagon.

[0061] In some specific embodiments, the mounting bracket 400 includes a base plate 410 fixedly connected to the insulating component 300, and a plurality of mounting plates 420 connected to the discharge electrode 500 are fixedly mounted on the base plate 410.

[0062] Please see Figure 2 and Figure 3 As shown, since the dust collecting electrode 600 has multiple tubes 610, the number of discharge electrodes 500 corresponds to the number and position of the tubes 610. Therefore, a discharge electrode 500 needs to be installed at each position of the tube 610, that is, the discharge electrode 500 at each position of the tube 610 needs to have a connection point. For this purpose, multiple mounting plates 420 are longitudinally arranged on the substrate 410 fixedly connected to the insulating member 320, and the mounting plates 420 can extend to each position of the tube 610, so that the end of the discharge electrode 500 can be connected to the mounting plate 420 to realize the installation of the discharge electrode 500.

[0063] In this embodiment, the mounting bracket 400 at the top can be energized to transmit electricity to each discharge electrode 500, thereby forming an electric field between each discharge electrode 500 and each tube 610 to capture dust particles in the exhaust gas, thus completing the exhaust gas dust removal.

[0064] In some specific embodiments, the air intake pipe 110 includes an air intake section 111 connected to the first cylinder 100, and an air outlet section 112 located inside the air intake pipe 110 is fixedly provided at the end of the air intake section 111. At least one guide plate 113 is provided inside the air outlet section 112.

[0065] Please see Figure 1 , Figure 6 as well as Figure 7 As shown, in order to ensure that the exhaust gas is evenly distributed in the first cylinder 100 and enters each pipe 610, multiple guide plates 113 are provided in the exhaust section 112 located in the first cylinder 100. This allows the exhaust gas to enter the first cylinder 100 from the intake section 111 through the exhaust section 112 and be evenly distributed therein. Furthermore, the exhaust port of the exhaust section 112 faces downward, which can prevent dust particles and water from entering the exhaust section 112. At the same time, it can also increase the time for the exhaust gas to diffuse evenly in the first cylinder 100 to a certain extent, thereby improving the uniformity of distribution.

[0066] In some specific embodiments, a flow equalization plate 120 is fixedly provided inside the first cylinder 100. The flow equalization plate 120 is located between the air outlet of the air inlet pipe 110 and the dust collection electrode 600. The flow equalization plate 120 includes a plate 121 fixedly connected to the first cylinder 100, and a plurality of flow equalization holes 122 are provided on the plate 121.

[0067] Please see Figure 8 As shown, in order to ensure that the exhaust gas from the first cylinder 100 enters each pipe 610 evenly, a flow equalization plate 120 is provided in the first cylinder 100 to distribute the gas evenly into the pipe 610, so that the amount of gas entering each pipe 610 is the same. Specifically, when the gas passes through the flow equalization plate 120, the exhaust gas is divided into several parts by the flow equalization holes 122, so that it is evenly transported and moved towards the pipe 610, making the amount of gas entering the pipe 610 approximately the same. The distribution of the flow equalization holes 122 can be designed according to the actual situation, and is not limited here.

[0068] In some specific embodiments, the number of air intake pipes 110 is M, where M≥1. When M≥2, a partition 123 is fixedly provided on the plate 121 to separate two adjacent air intake pipes 110.

[0069] Please continue reading. Figure 8As shown, in order to improve the intake efficiency, multiple intake pipes 110 can be installed on the first cylinder 100. In order to further improve the uniformity of gas distribution in the first cylinder 100, adjacent intake pipes 110 are separated by partitions 123, and then the gas is evenly distributed through the flow equalization holes 122 in the corresponding areas. In this embodiment, there are two intake pipes 110, that is, a partition 123 is set in the middle of the two intake pipes 110 to separate them. In other embodiments, the number of intake pipes 110 can also be three, four, etc., and the number of partitions 123 will increase accordingly.

[0070] In some specific embodiments, the bottom circumferential surface of the first cylinder 100 is connected to a manhole 130 and a sewage pipe 140 that communicate with its interior.

[0071] Please see Figure 5 As shown, the components in the first cylinder 100 can be replaced and installed through the manhole 130. The drain pipe 140 is located at the bottom of the first cylinder 100. Dust and water from each pipe 610 are collected at the drain pipe 140. Finally, the dust and water can be sucked out and cleaned by a pump or other suction device.

[0072] See Figure 9 As shown, this application embodiment also provides a dust removal system, which includes the dust removal device of any of the above and a hot air assembly 700. The hot air assembly 700 includes a fan 710 and a heater 720. The air outlet of the fan 710 is connected to the air inlet of the heater 720, and the air outlet of the heater 720 is connected to each insulating component 300.

[0073] Since the housing 310 of each insulating component 300 is connected to the air cavity, water vapor from waste will enter the interior of the housing 310, which may affect the insulation of the insulating component 320. Therefore, hot air is introduced into the insulating component 320 to achieve the drying effect, thereby keeping the insulating component 320 in a dry state and achieving the insulation effect.

[0074] Specifically, hot air can be provided to each insulating component 300 outside the dust removal device through the cooperation of fan 710 and heater 720. The hot air heated by heater 720 is delivered to each housing 310 through connecting pipe 730, thereby removing moisture from each housing 310 and keeping the insulating component 320 dry and maintaining its insulation.

[0075] In this embodiment, a corresponding spraying device can also be installed on the exhaust pipe 210 at the top of the second cylinder 200. The spraying device can include components such as water pipes, water pumps and spray heads, and can spray the pipe 610 at regular intervals to wash away the dust on its inner wall and keep it clean.
