Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, specifically relating to a wet electrostatic dust removal device. Background Technology

[0002] Wet electrostatic precipitators are a commonly used dust removal device. Their working principle involves flue gas passing through an electric field region with cathode wires. A high voltage is applied to the cathode wires, generating corona discharge, which charges the dust particles in the flue gas. Under the influence of the electric field, the charged dust particles move towards the anode tubes with opposite polarity and deposit on their inner walls. A spray system then washes away the acid mist adhering to the inner walls of the anode tubes. Existing patent CN118649781B discloses a high-efficiency, energy-saving honeycomb-type wet electrostatic precipitator, including a precipitator body. The precipitator contains multiple anode tubes arranged in a honeycomb pattern, with cathode wires suspended inside each anode tube. A spray system is installed on the inner wall of the precipitator. However, the spray system in existing precipitators is fixedly installed inside the housing and cannot be moved. This prevents the spray system from thoroughly cleaning the dust inside the metal spray tubes, leading to severe dust accumulation and affecting the dust removal efficiency. Therefore, a wet electrostatic precipitator needs to be designed to overcome the above difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a wet electrostatic dust removal device. This invention uses a lifting component and a horizontal moving component to move the spray frame, thereby adapting and adjusting the relative position of the spray frame and the metal pipe, resulting in high cleaning efficiency and more thorough cleaning, and better overall dust removal effect.

[0004] The objective of this invention is achieved through the following technical solution: A wet electrostatic precipitator includes an upper chamber and a lower chamber. An electric field assembly is provided between the upper and lower chambers. The electric field assembly includes two anode wire supports arranged side by side, and several uniformly distributed cathode wire assemblies are provided between the two anode wire supports.

[0008] By setting up a clamping bushing and sealing components, water inside the upper chamber is prevented from directly spreading to the porcelain insulator support, thus preventing corrosion of the porcelain insulator support and affecting the dust removal effect. By setting up a first fixed seat and a second fixed seat, it is convenient to install the porcelain insulator support. By setting up a locking handle, it is convenient to open and close the door panel, thus facilitating the replacement of the porcelain insulator support. The locking handle here is a T-type handle, which is an existing standard part, specifically model MS309-2.

[0009] Preferably, the lifting assembly includes a horizontal mounting plate, a lifting plate, and a pair of lifting cylinders. The lifting plate is provided with a horizontal moving component that can move relative to it. The lifting assembly and the horizontal moving component are symmetrically arranged on the left and right sides of the upper housing. The horizontal moving component is detachably connected to the spray frame, and a clamp assembly for fixing the two is provided between the horizontal moving component and the spray frame. The horizontal mounting plate is fixedly installed in the upper housing, and a lifting cylinder is fixedly installed on the lower end face of the horizontal mounting plate. The lifting plate is fixedly installed on the piston shaft of the lifting cylinder, and the horizontal moving component is slidably installed on the lifting plate.

[0010] Preferably, the horizontal moving assembly includes a strip plate, a drive motor, gears, and a rack; the strip plate is provided with several rollers rotatably connected thereto, and the lifting plate is provided with a guide limiting groove, in which the rollers are slidably installed; a rack is fixedly installed on the lower end face of the lifting plate, and a drive motor is fixedly installed on the strip plate; a gear is installed on the motor shaft of the drive motor, and the gear meshes with the rack; when the drive motor drives the gear to rotate, the strip plate moves axially along the guide limiting groove; a clamp assembly is provided between the strip plate and the spray frame to fix the two together.

[0013] Preferably, the spray frame is provided with paired water inlet channels, the outer layer of the upper box is provided with paired water inlets, and a telescopic hose is provided between the water inlets and the water inlet channels; the end of the spray frame facing the metal pipe is provided with several spiral water outlets, and the spiral water outlets are positioned towards the open end of the metal pipe; the lower box is provided with an air outlet channel, and the metal pipe is positioned between the air inlet channel and the air outlet channel.

[0014] When the lifting cylinder is working, it drives the lifting plate to move up and down, which facilitates the adjustment of the vertical distance between the spray frame and the metal pipe. The lifting plate has a guide limiting groove, and the rollers on the strip plate are positioned within the guide limiting groove. This allows the strip plate to move along the axial direction of the lifting plate when the drive motor rotates the gears. Because there is a certain gap between the spray frame and the metal pipe at the edge of the upper housing, the horizontal moving component controls the spray frame to move towards the edge of the upper housing, thus covering the entire metal pipe inside the upper housing for better dust removal. The adjusting screw on the clamp assembly allows for easy adjustment of the initial height of the spray frame, enabling the vertical distance between the spray frame and the metal pipe to be adjusted accordingly. The clamp body facilitates the connection between the spray frame and the strip plate. The spiral water outlet improves the spraying effect and expands the coverage area. A telescopic hose connects the water inlet and the water inlet channel; the telescopic hose is not shown in the accompanying drawings.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The lifting component and the horizontal moving component facilitate the movement of the spray frame relative to the metal pipe, thereby adapting and adjusting the spray frame, resulting in a wider spray coverage area, more thorough dust removal, and better dust removal effect; 2.

The lifting plate 512 is fixedly installed on the piston shaft of the lifting cylinder 513. The horizontal moving assembly 52 is slidably installed on the lifting plate 512. The horizontal moving component 52 includes a strip plate 521, a drive motor 522, a gear 523, and a rack 524. The strip plate 521 is provided with several rollers 525 rotatably connected to it.

A gear 523 is installed on the motor shaft of the drive motor 522, and the gear 523 meshes with the rack 524. When the drive motor 522 drives the gear 523 to rotate, the strip plate 521 moves axially along the guide limiting groove 514. A clamp assembly 7 is provided between the strip plate 521 and the spray frame 53 to fix them together. The width of the guide limiting groove 514 is adapted to the width of the roller 525, and the vertical height of the guide limiting groove 514 is adapted to the outer diameter of the roller 525.

The end of the adjusting screw 72 is threadedly connected to the mounting base 71, and the mounting base 71 is fixedly connected to the strip plate 521. The spray frame 53 is provided with a pair of water inlet channels 8, and the outer layer of the upper box 1 is provided with a pair of water inlets 9. A telescopic hose is provided between the water inlets 9 and the water inlet channels 8.

The lower box 2 is provided with an air outlet channel 11, and the metal pipe 33 is positioned between the air inlet channel 6 and the air outlet channel 11.

[0030] The specific operation process of this embodiment is as follows: Dust-containing flue gas enters the upper chamber 1 through the air inlet channel 6, then diffuses from the electric field component to the lower chamber 2, and finally exits through the air outlet channel 11. When the flue gas passes through the metal pipe 33, a high voltage is applied to the cathode wire assembly 32, so that the dust will move towards the anode wire support 31. During the movement, the dust will adhere to the inner wall of the metal pipe 33, and then be washed by the spray device 5.

When the drive motor 522 drives the gear 523 to rotate, the strip plate 521 can move along the axial direction of the lifting plate 512. Since there is a certain gap between the spray frame 53 and the metal pipe 33 at the edge of the upper box 1, the horizontal moving component 52 controls the spray frame 53 to move towards the edge of the upper box 1, so that the spray frame 53 covers the entire metal pipe 33 in the upper box 1, resulting in better dust removal effect. The initial height of the spray frame 53 can be easily adjusted by the adjusting screw 72 on the clamp component 7, so that the vertical distance between the spray frame 53 and the metal pipe 33 can be adjusted accordingly. The clamp body 73 facilitates the connection between the spray frame 53 and the strip plate 521. By setting the spiral water outlet 10, the spraying effect is better and the coverage is wider. By setting the clamping bushing 45 and the seal 44, the water source in the upper box 1 is prevented from directly spreading to the porcelain bottle support 41, thereby preventing the porcelain bottle support 41 from being corroded and affecting the dust removal effect. By setting the first fixing seat 410 and the second fixing seat 411, it is convenient to install the porcelain bottle support 41. By setting the locking handle 49, it is convenient to open and close the door panel 43, thereby facilitating the replacement of the porcelain bottle support 41.
