Description

Technical Field

[0001] The present application belongs to the technical field of electrostatic precipitator equipment, and in particular relates to a cathode mechanism and a radial flow electrostatic precipitator. Background Art

[0002] As an efficient and energy-saving air purification equipment, radial flow electrostatic precipitator has been widely used in the field of environmental protection in my country. Its working principle is to use high-voltage electric field to charge dust particles. The charged dust migrates to the collecting plate under the action of the electric field, thereby achieving dust collection and purification. Compared with traditional dust collectors, radial flow electrostatic precipitator has the advantages of high dust removal efficiency, small equipment footprint, simple operation and maintenance, etc., and is suitable for dust control in various industrial production processes.

[0003] The cathode mechanism of the radial flow electrostatic precipitator includes a cathode hanger, a main mast, a plurality of cathode wire frames, and a cathode wire. The insulating porcelain bottle is installed on the top plate of the radial flow electrostatic precipitator and fixed to the cathode hanger through a double nut. The cathode hanger is welded to the main mast through the top plate. A plurality of cathode wire frames are arranged on the main mast, and the cathode wire is installed on the cathode wire frame.

[0004] In the above structure, since the cathode wire frame is offset from the main mast axis by a certain distance, the center of gravity of the cathode structure deviates from the suspension center, causing the main mast to bend and deform due to gravity. In this case, the pole distances between the anode and cathode also change, resulting in a decrease in the dust removal effect of the radial flow electrostatic precipitator. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide a cathode mechanism and a radial flow electrostatic precipitator. The above scheme can solve the problem that the main mast is bent and deformed due to gravity, causing the pole distance between the anode and the cathode to change, resulting in a reduction in the dust removal effect of the radial flow electrostatic precipitator.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a cathode mechanism for a radial flow electrostatic precipitator, the cathode mechanism comprising:

[0008] A cathode structure, the cathode structure comprising a main mast, a cathode wire frame and a cathode wire, the cathode wire frame is arranged on the main mast, the cathode wire is arranged on the cathode wire frame, the main mast has a first end and a second end, the first end and the second end are opposite to each other;

[0009] A suspension structure, the suspension structure comprising a first suspension rod, a second suspension rod and a tension rod, the first suspension rod is connected to the first end, and the second suspension rod is connected to the second end via the tension rod;

[0010] The suspension center of the suspension structure and the center of gravity of the cathode structure are located in the same plane.

[0011] In the embodiment of the present application, the cathode mechanism is suspended by a suspension structure, that is, by a first suspension rod and a second suspension rod, the suspension center of the suspension structure and the center of gravity of the cathode structure are located in the same plane, and the main mast is pulled sideways by the second suspension rod and the pull rod, so that the main mast can be prevented from bending and deforming, which is conducive to ensuring the polar distance between the anode and the cathode. In addition, adding a side pull at the bottom of the main mast can effectively ensure the error of the polar distance and avoid the overall shaking of the structure causing a large fluctuation of the polar distance.

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] The cathode mechanism and radial flow electrostatic precipitator provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0024] like Figure 1 to Figure 2 As shown, an embodiment of the present application provides a cathode mechanism, which includes a cathode structure 100, a suspension structure 200, a first insulating porcelain bottle 300 and a second insulating porcelain bottle 400.

[0025] The cathode structure 100 includes a main mast 110, a cathode wire frame 120 and a cathode wire 130. The cathode wire frame 120 is arranged on the main mast 110, and the cathode wire 130 is arranged on the cathode wire frame 120. The extension direction of the cathode wire 130 is the same as the extension direction of the main mast 110. The main mast 110 has a first end 111 and a second end 112, and the first end 111 and the second end 112 are opposite to each other. The suspension structure 200 includes a first suspension rod 210, a second suspension rod 220 and a tie rod 230. The first suspension rod 210 is connected to the first end 111, and the second suspension rod 220 is connected to the second end 112 through the tie rod 230. The suspension center of the suspension structure 200 and the center of gravity of the cathode structure 100 are located in the same plane.

[0026] In the embodiment of the present application, the cathode mechanism is suspended by the suspension structure 200, that is, by the first suspension rod 210 and the second suspension rod 220, the suspension center of the suspension structure 200 and the center of gravity of the cathode structure 100 are located in the same plane, and the main mast is pulled sideways by the second suspension rod 220 and the pull rod 230, so that the main mast 110 can be prevented from bending and deforming, which is conducive to ensuring the polar distance between the anode and the cathode. In addition, the addition of side pulling at the bottom of the main mast 110 can effectively ensure the error of the polar distance and avoid the overall shaking of the structure causing a large fluctuation of the polar distance.

[0027] The first suspension rod 210 and the second suspension rod 220 extend in the same direction, that is, the first suspension rod 210 and the second suspension rod 220 are parallel, which is conducive to ensuring that the suspension center of the suspension structure 200 and the center of gravity of the cathode structure 100 are located in the same plane.

[0028] The cathode structure 100 further includes a connector 140, the first suspension rod 210 and the main mast 110 are both connected to the connector 140, and the main mast 110 is located on a side of the connector 140 away from the first suspension rod 210. The connector 140 facilitates the arrangement of the main mast 110 and the first suspension rod 210. The connector 140 is a connecting plate.

[0029] The cathode structure further includes a first insulating porcelain bottle 300 and a second insulating porcelain bottle 400. The first insulating porcelain bottle 300 is sleeved on the first suspension rod 210, and the second insulating porcelain bottle 400 is sleeved on the second suspension rod 220. The first insulating porcelain bottle 300 and the second insulating porcelain bottle 400 can ensure the insulation effect of the cathode structure 100.

[0030] The number of the suspension structures 200 corresponds to the number of the main masts 110, and there are two suspension structures 200. The two suspension structures 200 can make the suspension of the cathode mechanism more stable.

[0031] The number of the cathode wire frame 120 is one, that is, the cathode wire frame 120 is an integral wire frame, which is more conducive to ensuring that the suspension center of the suspension structure 200 and the center of gravity of the cathode structure 100 are located in the same plane.

[0032] The embodiment of the present application also provides a radial flow electrostatic precipitator, which includes the cathode mechanism, anode mechanism 500 and shell 600 of the above embodiment. The cathode structure 100 and the anode mechanism 500 are both arranged in the shell 600, and the cathode structure 100 and the anode mechanism 500 are arranged opposite to each other. The anode mechanism 500 is a mesh structure.

[0033] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
