Description

Technical Field

[0001] This utility model belongs to the field of demister technology, and in particular relates to an electrostatic demister that is easy to disassemble and assemble. Background Technology

[0002] Demisters play a crucial role in industrial production. They are mainly used to capture liquid droplets and small amounts of dust in flue gas, thereby reducing water carryover in the flue gas and preventing fan vibration and corrosion. Electrostatic precipitators are a type of precipitator, and they are devices that use electric charge to remove solid particles from gases or liquids. The working principle of an electrostatic precipitator is to generate static electricity through a high-voltage electric field, which ionizes gas molecules. Charged dust particles are adsorbed onto the dust collection plate under the action of the electric field, thereby achieving the effect of purifying the gas.

[0003] A search revealed an electrostatic demister disclosed in patent publication number CN219943208U. The demister includes a main body for purifying flue gas, with an internal adjustment component for adjusting the tension of the anode membrane installation. The adjustment component includes two telescopic members symmetrically positioned on a lower support beam within the inner cavity of the demister main body. Each telescopic member has a worm gear. The inner cavity of the demister main body contains a drive component capable of synchronously rotating the two worm gears and a support component for supporting the drive component. By rotating a handwheel, the two studs can be synchronously driven to rotate, achieving the effect of synchronously raising and lowering the two sleeves in one operation. This reduces the number of operation steps, offering the advantages of simple and convenient operation. It also effectively avoids the situation where the studs get stuck due to asynchronous rotation, making it suitable for widespread use. Furthermore, the worm gear and worm have self-locking properties, effectively preventing the worm from rotating back and ensuring the stability of the anode membrane after installation.

[0004] The aforementioned electrostatic precipitator includes: an electrostatic precipitator body for purifying flue gas and an adjusting assembly for adjusting the tension of the anode membrane installation within the inner cavity of the electrostatic precipitator body. The adjusting assembly is located within the inner cavity of the electrostatic precipitator body. The adjusting assembly includes two telescopic members symmetrically arranged on a lower support beam within the inner cavity of the electrostatic precipitator body. Each telescopic member is equipped with a worm gear. The inner cavity of the electrostatic precipitator body is equipped with a driving member capable of driving the two worm gears to rotate synchronously and a support member for supporting the driving member. The driving member includes a worm gear horizontally and movably connected to the inner cavity of the electrostatic precipitator body. Both ends of the worm gear mesh with the two driving members respectively. The electrostatic precipitator body includes a base, and a tower body is installed on the top of the base. One end of the worm gear is rotatably connected to the inner wall of the tower body through a bearing. The telescopic member includes a support plate fixedly connected to the inner wall of the tower body. A stud is rotatably connected to the top via a bearing. The inner wall of the worm gear is fixedly connected to the surface of the stud. A threaded sleeve is threaded onto the surface of the stud, and a connecting block is fixedly connected to the top of the sleeve. The connecting block is located at the bottom of the support beam inside the base cavity. The surface of the sleeve is equipped with a guide for limiting movement. When the worm gear drives the stud to rotate, the threaded sleeve can move up and down along the central axis of the stud, thereby adjusting the installation tension of the anode membrane. However, the stability of the anode membrane after adjustment is poor, resulting in unstable tension and affecting the electrostatic precipitator effect. Furthermore, the complex structure makes maintenance difficult. In addition, multiple sets of connecting parts are required during installation to improve the stability of the electrostatic precipitator after installation, which results in cumbersome operation steps, increased workload, and reduced disassembly and assembly efficiency of the electrostatic precipitator.

[0005] To address these issues, we provide an electrostatic precipitator that is easy to assemble and disassemble. Utility Model Content

The gas is discharged through the outlet pipe 104. Example 2

[0034] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 Based on the first specific embodiment, an adjustment component 2 is provided.

The motor 201 is started, the lead screw 201b rotates, and when the two ball nuts 201c move towards each other, the connecting rod 206 moves through the hinge 207, the connecting plate 208 moves downward, and the distance between the connecting plate 208 and the top plate 203 gradually increases; when the two ball nuts 201c move in opposite directions, the five-sleeve seat 205 moves in opposite directions, the connecting plate 208 moves upward, and the distance between the connecting plate 208 and the top plate 203 gradually decreases, thereby realizing the adjustment of the anode membrane tension. Example 3

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 Based on specific embodiments one and two, a disassembly and assembly component 3 is provided.

By rotating the screw 303, the height of the support platform 303a is adjusted to realize the positional relationship between the plug rod 304 and the socket 301a, thereby realizing the disassembly and assembly of the electrostatic precipitator housing 1. This simplifies the operation steps and helps to speed up the disassembly and assembly efficiency of the electrostatic precipitator housing 1.

[0039] Specifically, the ear bracket 302 is connected to the side wall of the base plate 202, and a mounting bracket 301 is provided below the ear bracket 302. The side wall of the ear bracket 302 has a through hole 302a, and the side wall of the mounting bracket 301 has an insertion hole 301a. A support platform 303a is provided on the lower surface of the ear bracket 302, and a connecting screw 303 is provided on the upper surface of the support platform 303a. The upper end of the screw 303 passes through the ear bracket 302 and is threadedly connected to the ear bracket 302.
