Description

Technical Field

[0001] The present application belongs to the technical field of electrostatic precipitators, and in particular, relates to an electrostatic precipitator. Background Art

[0002] The electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate smoke from flue gases emitted by stoves or oil-fired boilers, thereby significantly reducing the amount of smoke discharged into the atmosphere. It is an important environmental protection equipment for improving environmental pollution and improving air quality.

[0003] The principle of the electrostatic precipitator is: when the flue gas passes through the flue in front of the main structure of the electrostatic precipitator, the smoke dust is positively charged, and then the smoke gas enters the electrostatic precipitator channel with multiple layers of cathode plates. Due to the mutual adsorption between the positively charged smoke dust and the cathode plate, the particles in the smoke are adsorbed on the cathode, and the cathode plate is hit regularly, so that the smoke dust with a certain thickness falls into the ash hopper under the electrostatic precipitator structure under the dual effects of self-weight and vibration, thereby achieving the purpose of removing smoke dust in the flue gas.

[0004] The patent with publication number CN106622664B discloses an electrostatic precipitator, including a box body, the box body has an air inlet and an air outlet, the box body has a partition plate, the partition plate divides the box body into an air inlet chamber connected to the air inlet and a dust removal chamber connected to the air outlet, the dust removal chamber has a discharge component, the dust removal chamber is provided with a cathode plate, the air inlet chamber has an air inlet diversion structure, and the air inlet diversion structure has a flue gas pretreatment component.

[0005] In the above autobiography, a side door is set in the air intake chamber. When the equipment needs maintenance, the side door can be opened to replace the activated carbon and clean the accumulated dust. Although the dust can be cleaned to a certain extent, in actual maintenance situations, directly opening the side door or the top cover will be affected by the airflow, and the accumulated dust inside the electrostatic precipitator will gush out and spread around, which will affect the surrounding environment and the subsequent cleaning and maintenance work of the staff. Improvement is needed. Utility Model Content

[0006] The purpose of this application is to provide an electrostatic precipitator that can solve the above problems.

[0007] The purpose of this application is to provide an electrostatic precipitator, comprising:

[0008] A shell body having a cavity inside, a top cover on the top, and a base on the bottom;

[0009] A pole plate is arranged in the shell and connected to the top cover, and a plurality of pole plates are provided;

[0010] A cleaning device, disposed in the housing and used for cleaning the electrode plate;

[0011] Wherein, a dustproof cloth is arranged between the adjacent electrode plates, and the dustproof cloth is detachably connected to the shell.

[0012] By adopting the above-mentioned electrostatic precipitator and setting a plurality of pole plates, the electrostatic precipitator can more effectively capture and remove dust particles in the air. The pole plates are connected to the top cover so that when the top plate is lifted, the pole plates can be lifted together. By setting a cleaning device, the dust on the pole plates can be regularly cleaned. At the same time, by setting a dustproof cloth, dust can be prevented from gushing out and spreading to the surroundings when the top plate is opened and the pole plates are taken out, thereby ensuring the surrounding environment and facilitating subsequent cleaning and maintenance work by the staff. In addition, the detachable connection between the dustproof cloth and the shell makes cleaning and replacement simple and quick, and extends the service life.

[0013] Furthermore, the cleaning device comprises:

[0014] A cleaning mechanism is disposed in the housing and in contact with both sides of the electrode plate;

[0015] An ejection mechanism is arranged on the shell and connected to the top cover;

[0016] The number of cleaning mechanisms is the same as the number of pole plates, the ejection mechanism is used to lift up the top cover, and the cleaning machine hook is used to clean the dust on the pole plates.

[0017] The number of cleaning mechanisms is the same as the number of plates, which ensures that each plate can be fully cleaned, thereby improving the cleaning efficiency of the dust collector and extending the service life of the plates. The cleaning mechanism directly contacts both sides of the plate and can be cleaned without removing the plate, which improves the convenience and efficiency of operation. At the same time, since the ejection mechanism can lift the top cover, the cleaning mechanism can also clean the plate during the lifting process, and after lifting, the inside of the shell can be thoroughly cleaned and maintained.

[0018] In addition, the use of cleaning equipment for automatic cleaning can reduce dependence on manual labor to a certain extent, reduce labor intensity, and improve the accuracy and consistency of cleaning. Regular cleaning of dust on the plates can reduce wear and corrosion on the plates, thereby extending the service life of the dust collector. It can also prevent the weakening of the electric field and the decrease in dust removal efficiency caused by excessive dust accumulation, ensuring the continuous and efficient operation of the dust collector. The cleaned dust will fall to the bottom of the cavity, and the base of the cavity is provided with a dust box for collecting dust.

[0019] Further: the cleaning mechanism comprises:

[0020] A mounting frame, which is sleeved outside the electrode plate and has a through slot inside for the electrode plate to pass through;

[0021] Brush hairs are arranged on the inner wall of the mounting frame and in contact with the electrode plate;

[0022] A guide slot is provided in the housing, and a movable seat adapted to the guide slot is provided on the mounting frame, and the movable seat can slide on the guide slot;

[0023] The movable seat can drive the mounting frame to move up and down along the pole plate.

[0024] The bristles are arranged on the inner wall of the mounting frame and in close contact with the plate, ensuring that the dust on the plate can be thoroughly cleaned. As the mounting frame moves up and down, the bristles can clean the surface of the plate comprehensively and evenly, improving the cleaning efficiency. Each plate is equipped with a corresponding cleaning mechanism, achieving a one-to-one cleaning effect, ensuring that each plate can be fully cleaned, and avoiding the decrease in dust removal efficiency caused by inadequate cleaning. The mounting frame slides on the guide slide groove through the moving seat, and the position of the cleaning mechanism can be adjusted as needed, making the cleaning process more flexible and adaptable to changes in the position and size of different plates. At the same time, the mounting frame is sleeved outside the plate, and a through groove for the plate to pass through is provided inside, which can prevent the mounting frame from colliding with the plate when moving, and avoids damage to the plate during the cleaning process. Through automatic control, the cleaning mechanism can automatically move up and down, reducing the need for manual intervention, not only improving the cleaning efficiency, but also reducing the labor intensity of the operator.

[0025] Furthermore, a rack is provided on the guide slide groove, and the movable seat includes an internal driver and a gear connected to the internal driver, and the gear is meshed with teeth on the rack.

[0026] The guide chute is installed in the shell of the electrostatic precipitator as the guide track of the moving seat. A rack is provided on the guide chute. The teeth on the rack provide an interface for the gear to mesh, so as to achieve power transmission and precise positioning. The moving seat is responsible for driving the mounting frame to move up and down along the plate. The driver is set on the moving seat to provide power. The internal driver is connected to the gear, and the gear meshes with the rack on the guide chute. When the internal driver is started, it drives the gear to rotate, and then through the meshing relationship between the gear and the rack, the moving seat slides on the guide chute.

[0027] When the plate needs to be cleaned, the internal driver starts, driving the gear to rotate, and the gear engages with the rack, causing the movable seat to slide on the guide groove. The movable seat drives the mounting frame to move up and down along the plate, and the bristles contact the plate to remove dust on the plate, effectively improving the cleaning efficiency, reducing the need for manual intervention, and reducing labor intensity.

[0028] Furthermore, the ejection mechanism comprises:

[0029] A mounting groove is provided on the housing;

[0030] A hydraulic cylinder is arranged in the mounting groove, and an output shaft of the hydraulic cylinder is connected to the top cover;

[0031] A buffer groove is arranged at one side of the mounting groove, a buffer member is arranged inside the buffer member, and the other end of the buffer member is connected to the top cover;

[0032] There are multiple installation slots, which are respectively arranged at four corners of the shell.

[0033] The top cover can be smoothly lifted and lowered by connecting the output shaft of the hydraulic cylinder to the top cover. The stability of the top cover during the lifting process can also be ensured to a certain extent. By setting a buffer groove, the buffer groove and the buffer member inside it provide additional protection for the lifting of the top cover. When the top cover is lifted and lowered, the buffer member can avoid the impact between the top cover and the shell, and avoid possible damage or loosening. There are multiple mounting grooves, which are respectively located in each corner of the shell. The multi-point support design ensures that the top cover is evenly stressed during the lifting process. Through the combined use of the hydraulic cylinder and the buffer member, the ejection mechanism can provide additional safety protection while ensuring the stable lifting of the top cover.

[0034] Furthermore, the buffer member includes:

[0035] A connecting rod, one end of which is connected to the top cover and the other end of which extends into the buffer groove;

[0036] A connecting slider is disposed in the buffer groove and can slide in the buffer groove, and one end of the connecting slider is connected to the other end of the connecting rod;

[0037] A damper is arranged in the buffer groove, and the telescopic end of the damper is connected to the other end of the connecting slider;

[0038] The utility model also includes an elastic member, which is sleeved outside the damper, and two ends of the elastic member are respectively connected to the connecting slider and the buffer groove.

[0039] The buffer member includes a connecting rod, a buffer slider, a damper and an elastic member. During the opening and closing process of the top cover, the damper is set to damp and buffer the opening and closing process during the closing and opening process of the top cover, so that the top cover can be opened and closed stably, and the top cover can be prevented from being unstable during the closing and opening process. The pole plate connected to the top cover can also be protected. At the same time, when the connecting slider slides in the buffer groove, it can also drive the elastic member to expand and contract. In conjunction with the damper, the buffer effect can be further improved, making the opening and closing process of the top cover more stable.

[0040] The beneficial effects of this application are:

[0041] 1. By setting up a cleaning device, the dust on the plate can be removed regularly. At the same time, by setting up a dustproof cloth, dust can be prevented from gushing out and spreading around when the top plate is opened and the plate is taken out, thereby ensuring the surrounding environment and facilitating the subsequent cleaning and maintenance work of the staff;

[0042] 2. When the plate needs to be cleaned, the internal driver starts, driving the gear to rotate, the gear meshes with the rack, and the moving seat slides on the guide slot. The moving seat drives the mounting frame to move up and down along the plate, and the bristles contact the plate to remove the dust on the plate, which effectively improves the cleaning efficiency, reduces the need for manual intervention, and reduces labor intensity;

[0043] 3. By setting a damper, the opening and closing process can be damped and buffered, so that the top cover can be opened and closed stably, preventing the top cover from being unstable during the closing and opening process, and protecting the pole plate connected to the top cover. At the same time, when the connecting slider slides in the buffer groove, it can also drive the elastic part to expand and contract. The damper can further improve the buffering effect and make the opening and closing process of the top cover more stable. BRIEF DESCRIPTION OF THE DRAWINGS
