Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrostatic precipitator technology, and in particular relates to an electrostatic precipitator with a cathode wire anti-sway reinforcement device. Background Technology
[0002] Electrostatic precipitators are important environmental protection devices that remove particulate matter from exhaust gases, significantly reducing the amount of dust emitted into the atmosphere. Wet scrubbers are one of the important dust removal methods, and the cathode wire is a key component of wet electrostatic precipitators.
[0003] During dust removal, due to the large length of the cathode wire, especially in situations with large flue gas volume and high flue gas velocity, the cathode system is easily blown by the flue gas and sways. This swaying and displacement of the cathode system makes it impossible to guarantee the electrode distance between the cathode and anode systems, which directly affects the working performance of the entire dust removal system and greatly reduces its dust removal effect. Even worse, if the swaying and displacement of the cathode system reaches a certain distance, it can cause direct contact between the cathode and anode systems, resulting in a short circuit and potentially leading to a safety accident.
[0004] The existing technology mainly prevents the cathode system from swaying by suspending a weight at the end of the cathode wire in the cathode system. The weight of the weight itself pulls the cathode wire taut in the vertical direction, thereby preventing the cathode wire from swaying. For example, patent number CN202310029530.8 discloses an anti-swaying device for the cathode wire of an electrostatic precipitator. However, the above method still results in the cathode wire swaying when the airflow velocity is high. Utility Model Content
[0005] The purpose of this invention is to provide an electrostatic precipitator with a cathode wire anti-sway reinforcement device to solve the technical problem of unstable cathode wire connection in existing electrostatic precipitators, which makes the cathode wires prone to swaying in situations with high airflow velocity.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an electrostatic precipitator with a cathode wire anti-sway reinforcement device, comprising an electrostatic precipitator body, wherein anti-sway reinforcement devices are provided at the upper and lower ends of the electrostatic precipitator body, and a plurality of cathode wires and anode plates are alternately arranged between the anti-sway reinforcement devices. The anti-sway reinforcement device includes a support frame and a reinforcement guide, wherein a plurality of limiting grooves are provided in the support frame, and both ends of the cathode wires extend into the limiting grooves through the slots opened on one side of the support frame and are limited and fixed by a locking component, and the reinforcement guide is correspondingly provided on the outside of the slots.
[0007] Preferably, the support frame includes a base frame and an outer cover, the limiting grooves are spaced apart on the base frame, the limiting grooves are provided with mounting posts, the cathode wires are provided with fixing holes on both sides that match the mounting posts, and the cathode wires are detachably installed in the support frame through the fixing holes and the mounting posts.
[0008] Preferably, the locking assembly includes a locking bolt, the mounting post has an internal threaded hole, the outer cover has a through hole corresponding to the internal threaded hole, and the locking bolt passes through the through hole and is screwed into the internal threaded hole to fix the bottom frame, the outer cover and the cathode wire.
[0009] Preferably, the reinforcing guide is integrally formed on one side of the support frame, and the reinforcing guide has a guide groove for the cathode wire to pass through. The guide groove and the slot opening are connected, and the cathode wire extends into the support frame through the reinforcing guide.
[0010] Preferably, adjacent anode plates enclose each other to form an anode cylinder, and the two ends and the upper and lower end support frames of the anode cylinder are fixedly connected, and the cathode wire is arranged at the center of the anode cylinder.
[0011] Preferably, the cathode wire and the anode plate are arranged in parallel, and the cathode wire includes a rod body and a discharge needle end disposed on the outer periphery of the rod body.
[0012] Preferably, the electrostatic precipitator body has an air inlet and an exhaust outlet at both ends, and the electrostatic precipitator body also has a first power supply component and a second power supply component, which are used to supply power to the cathode wire and the anode plate, respectively.
[0013] By using the above technical solution, this utility model has the following beneficial effects compared with the prior art: by setting anti-sway reinforcement devices at the upper and lower ends of the electrostatic precipitator body, wherein the anti-sway reinforcement device includes a support frame and a reinforcement guide, a limiting groove is opened in the support frame, and the reinforcement guide is connected to the limiting groove. When it is necessary to fix the cathode wire, first open the outer cover at the top of the support frame, then extend both ends of the cathode wire through the guide groove on the reinforcement guide to the limiting groove of the support frame, then insert the fixing hole on the cathode wire into the mounting post located in the limiting groove, then put the outer cover back on, and fix the cathode wire in the support frame by means of threaded connection between the locking bolt and the mounting post.
[0014] By fixing both ends of the cathode wire to the support frame in the above manner, the stability of the connection between the cathode wire and the support frame is improved. This effectively prevents the cathode wire from swaying even in situations with high airflow velocities, keeping the cathode wire taut at all times and thus improving the reliability of equipment operation.
[0015] In addition, by setting up a reinforced guide, it can not only guide the cathode wire during installation, but also strengthen the connection between the end of the cathode wire and the support frame, thereby further improving the stability of the connection between the cathode wire and the support frame and more effectively reducing the sway amplitude of the cathode wire. This solves the technical problem of unstable cathode wire connection in existing electrostatic precipitators and easy swaying of the cathode wire in situations with high airflow velocity.

[0027] like Figure 1-4 As shown: An electrostatic precipitator with a cathode wire anti-sway reinforcement device includes an electrostatic precipitator body 1. Anti-sway reinforcement devices are provided at the upper and lower ends of the electrostatic precipitator body 1. A number of cathode wires 3 and anode plates 4 are alternately arranged between the anti-sway reinforcement devices. The anti-sway reinforcement device includes a support frame 2 and a reinforcement guide part 5. A number of limiting grooves 201 are opened in the support frame 2. The two ends of the cathode wires 3 extend into the limiting grooves 201 through the grooves 202 opened on one side of the support frame 2 and are limited and fixed by a locking component. The reinforcement guide part 5 is correspondingly arranged on the outside of the grooves 202.
[0028] The support frame 2 is fixedly installed inside the main body 1 of the electrostatic precipitator by means of detachable connection or integral molding. The cathode wire 3 and the anode plate 4 are arranged vertically between the upper and lower support frames 2 at intervals. The shape of the limiting groove 201 matches the end of the cathode wire 3. Both ends of the cathode wire 3 can be flatly accommodated in the limiting groove 201. The reinforcing guide part 5 is correspondingly provided on one side of each limiting groove 201. The reinforcing guide part 5 plays a guiding role to facilitate installation.
[0029] like Figure 1-3As shown: The support frame 2 includes a bottom frame 203 and an outer cover 204. Limiting grooves 201 are spaced apart on the bottom frame 203. Mounting posts 205 are provided in the limiting grooves 201. Fixing holes matching the mounting posts 205 are provided on both sides of the cathode wire 3. The cathode wire 3 is detachably installed in the support frame 2 through the fixing holes and the mounting posts 205. In this embodiment, the bottom frame 203 and the outer cover 204 are fastened together to support the support frame 2. The limiting grooves 201 inside will form a number of chambers for mounting the cathode wire 3. The mounting posts 205 and the bottom frame 203 are integrally formed. The above structure makes it easier to assemble the support frame 2 and the cathode wire 3 and the connection is stable and has high strength.
[0030] like Figure 1 As shown: The locking assembly includes a locking bolt 6, an internal threaded hole in the mounting post 205, and a through hole 206 on the outer cover 204 corresponding to the internal threaded hole. The locking bolt 6 passes through the through hole 206 and is screwed into the internal threaded hole to fix the bottom frame 203, the outer cover 204 and the cathode wire 3. The cathode wire 3 is further tightened by the threaded connection, which improves the stability of the connection and makes it easier to disassemble and assemble.
[0031] like Figure 1-3 As shown: The reinforcing guide part 5 is integrally formed on one side of the support frame 2. The reinforcing guide part 5 has a guide groove 501 for the cathode wire 3 to pass through. The guide groove 501 is connected to the slot 202. The cathode wire 3 extends into the support frame 2 through the reinforcing guide part 5. The reinforcing guide part 5 is integrally formed on one side of the support frame 2 by casting or welding to improve the connection strength between the two.
[0032] In this embodiment, adjacent anode plates 4 surround each other to form an anode cylinder, and the two ends of the anode cylinder and the upper and lower end support frames 2 are fixedly connected. The cathode wire 3 is arranged at the center of the anode cylinder.
[0033] like Figure 4 As shown: the cathode wire 3 and the anode plate 4 are arranged in parallel. The cathode wire 3 includes a rod body 301 and a discharge needle end 302 arranged on the outer periphery of the rod body 301.
[0034] like Figure 4 As shown: The electrostatic precipitator body 1 has an air inlet and an exhaust outlet at both ends. The electrostatic precipitator body 1 also has a first power supply component and a second power supply component, which are used to supply power to the cathode wire 3 and the anode plate 4, respectively.
[0035] By selecting the power supply components, the power supply voltage of the second power supply component can be greater than that of the first power supply component. This is because the cathode wire 3, i.e. the discharge electrode, is mainly used for the discharge of the discharge needle end 302, and its maximum voltage is limited. On the other hand, the anode plate 4, i.e. the dust collecting electrode, is used to establish high voltage and can withstand higher voltage. Therefore, a second power supply component with a higher voltage can be connected.
[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
