Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, and more specifically, to a cathode wire connection structure for use in wet electrostatic precipitators. Background Technology

[0002] In hazardous waste incineration production lines, wet electrostatic precipitators (WEESPs) are key dust removal equipment, and their performance and stability directly affect the environmental protection effect and operating cost of the entire system. The cathode system, as the core component of the WEESP, mainly includes cathode wires and cathode mounting frames. High-voltage power supply causes corona discharge in the cathode wires, achieving electrostatic adsorption and collection of dust.

[0003] Existing technology, application CN214320520U, discloses a stainless steel tubular barbed cathode wire for wet electrostatic precipitators and demisting, comprising electrodes and barbs. The cathode wire is relatively long, and its bottom is maintained vertically solely by its own weight or a simple fixing method. Under the impact of high-speed airflow, equipment vibration, or periodic flushing water, the cathode wire is prone to swaying, shaking, and even tangling. Furthermore, when the cathode wire passes through holes in the anode plate, if the hole design is unreasonable or the cathode wire is not securely fixed, direct contact can easily occur, leading to a short circuit between the anode and cathode, causing electric field paralysis. Currently, there is a lack of a novel cathode wire connection structure that effectively allows for cathode wire swaying, is easy to maintain, and is corrosion-resistant. Utility Model Content

[0004] The purpose of this invention is to provide a cathode wire connection structure for use in wet electrostatic precipitators, so as to solve the problem that the cathode wire is prone to shaking in the prior art and to avoid contact between the cathode wire and the anode plate.

[0005] This utility model is achieved through the following technical solution: A cathode wire connection structure for use in a wet electrostatic precipitator includes several crossbeams and an anode plate. Several cathode wires are provided on the crossbeams. Each cathode wire includes an electrode wire and a clamp, with a weight at the bottom of the electrode wire. The clamp is first clamped onto the crossbeam, and then the clamp is fixed to the electrode wire by bolts. The electrode wire of the cathode wire passes through the anode plate and is connected to a connecting beam.

[0006] Furthermore, the cathode wire material is stainless steel.

[0007] Furthermore, a connecting post is welded to the bottom of the polar line, and the connecting post passes through the positioning frame of the connecting beam to fix the drop hammer.

[0008] Furthermore, the connecting post is provided with external threads, and the drop hammer is sleeved on the connecting post and fixed by a nut.

[0009] Furthermore, the anode plate is provided with several through holes; the anode plate and the cathode wire are in a non-contact fit.

[0010] Furthermore, the through hole is hexagonal or circular in shape.

[0011] Furthermore, the polar line is provided with several barbs.

[0012] Furthermore, the connecting beam includes several positioning frames and reinforcing ribs; the positioning frames are fixedly connected by the reinforcing ribs; the connecting beam is made of insulating material; and the connecting beam is suspended in the air.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention connects the cathode wires into a single frame via connecting beams and incorporates weights at the bottom of the cathode wires. This suppresses the swaying of individual cathode wires under the impact of airflow or water flow, preventing changes in electrode spacing and short circuits between the cathode and anode caused by shaking, thus ensuring a stable electric field and high-voltage operation. A clamp is provided at the top of the cathode wires to increase the contact area between the crossbeam and the cathode wires, preventing overheating, ensuring stable current transmission, and enhancing the reliability of the mechanical connection.

Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Example 1: A cathode wire connection structure applied to a wet electrostatic precipitator, such as... Figures 1-4As shown, the device includes several cathode beams 1 and an anode plate 6. Several cathode wires are mounted on the beams 1. Each cathode wire includes an electrode wire 4 and a clamp 2. The clamp 2 is made of stainless steel, with an inner diameter of 100mm, a wrap angle of 360°, an opening width of 25mm, and a width of 50mm. It has 10mm diameter through holes drilled on both sides. A drop hammer 8 is located at the bottom of the electrode wire 4. The clamp 2 clamps the beams 1 and is fixed to the electrode wires 4 by M10 bolts 3. The electrode wires 4 pass through the anode plate 6 and are connected to a connecting beam. The clamp 2 not only firmly clamps the beams 1 but also increases the contact area between the beams 1 and the cathode wires, reducing contact resistance, preventing overheating, ensuring stable current transmission, and enhancing the reliability of the mechanical connection.

[0019] Example 2: A cathode wire connection structure for a wet electrostatic precipitator, wherein the cathode wire is made of stainless steel and has a flat shape. Stainless steel has corrosion resistance, extends equipment life, and prevents cathode wire deformation and breakage.

[0020] The bottom of the electrode 4 is welded with a connecting post 11 with a diameter of 8mm and a length of 180mm. The connecting post 11 passes through the positioning frame 7 of the connecting beam and then fixes the drop hammer 8. The connecting post 11 is provided with external threads 12. The drop hammer 8 is sleeved on the connecting post 11 and fixed by a nut 9. This mechanical connection method is more robust, reliable, and adjustable than traditional welding or binding. During installation, the tension of each cathode wire can be finely adjusted by the nut 9 to ensure that all electrode wires 4 are in the optimal vertical position.

[0021] The anode plate 6 has several through holes; the anode plate 6 and the cathode wire are in a non-contact fit. The through holes are hexagonal or circular in shape. This ensures that the cathode wire will not contact the anode plate 6 within its maximum expected swing range.

[0022] Several barbs 5 are provided on the electrode wire 4 to improve dust removal efficiency. The connecting beam includes several positioning frames 7 and reinforcing ribs 10; the positioning frames 7 are fixedly connected by the reinforcing ribs 10, and the connecting beam is made of insulating material; the connecting beam is suspended. Traditionally, a single cathode wire is freely suspended at the bottom and is prone to swaying. This structure connects multiple cathode wires into a single frame through the connecting beam at the bottom. This fixes the bottom of all cathode wires, forming a stable lower plane; it suppresses the swaying of a single cathode wire under the impact of airflow or water flow, fundamentally avoiding changes in electrode spacing and short circuits between cathodes and anodes caused by swaying, ensuring the stability of the electric field and high-voltage operation. Other aspects are the same as in Embodiment 1.

[0023] During installation, the top of a single cathode wire is passed through the clamp 2 and secured with bolts 3. The electrode body is pulled downwards and, after passing through the anode plate 6, the connecting column 11 passes through the connecting beam and the plumb bob 8, and the plumb bob is secured with nuts 9. The positioning frames 7 in the connecting beam are fixed to each other by reinforcing ribs 10. The overall electrode spacing is adjusted and an energization test is performed to ensure uniform electric field distribution, no shaking of the cathode wire, and good current conduction.

[0024] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
