Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to an energy-saving electrostatic dust removal device with integrated settling function. Background Technology

[0002] Industrial production generates a large amount of flue gas containing a lot of dust. The dust is complex and consists of particles of varying sizes. To ensure environmental protection, electrostatic precipitators are used to collect these dust particles. However, large dust particles in the flue gas continuously scour the electrostatic precipitator's plates, causing significant wear and affecting the lifespan and dust removal efficiency of the precipitator.

[0003] In related technologies, the common treatment method is to place a settling device before the electrostatic precipitator to filter large dust particles. The settling device uses multiple baffles to change the speed and direction of the dust, so that the large dust particles settle and separate. This dust removal method reduces the flow velocity of the flue gas, which not only affects the flue gas treatment efficiency, but also leads to increased pipeline pressure and is prone to leakage problems. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving electrostatic dust removal device with integrated settling function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving electrostatic precipitator with integrated settling function, comprising an electrostatic precipitator connected to an air inlet pipe, the air inlet pipe connected to a housing, a motor mounted on the surface of the housing, and the output shaft of the motor inserted into the interior of the housing;

[0006] A snap-fit ​​bracket is connected to the output shaft of the motor. A dust baffle is installed on the snap-fit ​​bracket. The output shaft of the motor is fixed to the dust baffle by a locking device, which simplifies the disassembly and assembly process of the dust baffle. When too much dust adheres to the surface of the dust baffle and affects the effect, it can be quickly disassembled for cleaning or replacement.

[0007] A dust collection box is connected to the lower surface of the outer shell. The outlet of the dust collection box is equipped with a valve to control dust discharge. The valve can also discharge dust at regular intervals according to the amount of dust accumulation, reducing the frequency of manual operation.

[0008] Dust-laden flue gas enters the dust baffle shell. Some of the dust falls into the dust collection box after colliding with the dust baffle. The motor drives the dust baffle to rotate, which can reduce the flow resistance of the flue gas in the shell, reduce airflow eddies and impact losses, and indirectly reduce the energy consumption of fans and other supporting equipment, thus having an energy-saving effect.

[0009] Furthermore, the electrostatic precipitator is connected to a first horn tube and a second horn tube on both sides. The first horn tube and the second horn tube are equipped with flanges. The air inlet pipe is connected to the second horn tube, which makes the flue gas flow into and out of the electrostatic precipitator smoother and improves the electrostatic precipitator effect. A connecting pipe is provided in the middle of the outer shell surface to facilitate the connection between the outer shell and external pipes.

[0010] Furthermore, the outer casing is equipped with a maintenance plate. By opening the maintenance plate to maintain the dust baffle, the entire outer casing can be removed without disassembling it, which greatly simplifies the maintenance process, saves maintenance time and costs, and improves the ease of maintenance of the maintenance plate.

[0011] Furthermore, both the outer casing and the inspection plate are fixedly connected with connecting ears, which are screwed with bolts to ensure the connection between the inspection plate and the outer casing, prevent flue gas leakage, and allow the inspection plate to be quickly opened by removing the bolts, thus balancing sealing and ease of maintenance.

[0012] Furthermore, the clip frame has a plug-in slot, into which the dust baffle is inserted, simplifying the dust baffle assembly process, shortening the device production and assembly time, and reducing production and manufacturing costs; at the same time, the plug-in structure also facilitates the quick disassembly of the dust baffle, improving the efficiency of later maintenance.

[0013] Furthermore, the snap-fit ​​bracket is screwed with an anti-detachment bolt, which passes through the dust baffle plate. This effectively prevents the dust baffle plate from coming out of the insertion slot during high-speed rotation due to centrifugal force, airflow impact, and other factors. This avoids the dust baffle plate from colliding with the outer casing or motor output shaft after falling off, causing equipment damage. At the same time, it prevents dust from losing its interception function due to the dust baffle plate falling off, which would lead to a sudden increase in the subsequent dust removal load, thus ensuring the safety of the device operation and the stability of the dust removal effect.

[0014] Furthermore, the valve includes a frame in which a valve plate is installed. An electric cylinder connected to the valve plate is installed on the frame. The electric cylinder drives the valve plate to automatically open and close the valve. The dust discharge time or dust discharge conditions can be set according to the amount of dust accumulated in the dust collection box (e.g., monitored by a level gauge). There is no need for manual operation of the valve, which reduces labor costs and avoids dust overflow or dust collection box blockage caused by untimely manual operation.

[0015] Furthermore, the inner wall of the frame has a sliding groove, and the valve plate slides inside the sliding groove to guide the movement trajectory of the valve plate, ensuring that the valve plate slides along a fixed path during opening and closing, avoiding friction or collision between the valve plate and the inner wall of the frame due to deviation, reducing mechanical wear between the valve plate and the frame, and extending the service life of the valve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The motor drives the dust baffle to rotate through the clamp. The rotating dust baffle will not excessively obstruct the flow of flue gas, reduce pipeline pressure, maintain flue gas flow rate, and ensure flue gas treatment efficiency. By controlling the speed of the motor to change the speed of the dust baffle, it can also assist the flow of flue gas. The rotating dust baffle has centrifugal force, which can reduce the adhesion of large dust particles and eliminate the need for frequent maintenance.

[0018] (2) The flue gas carrying dust is guided into the shell through the air inlet pipe. Large dust particles hit the dust baffle and fall down into the dust collection box. The large dust particles settle by gravity, which can clean most of the large dust particles, prevent the large dust particles from continuously scouring the electrostatic precipitator plates, reduce the continuous scouring of the electrostatic precipitator plates, reduce plate wear, ensure the stable dust removal effect of the plates, and extend the service life of the plates.

[0019] (3) After opening the inspection plate, unscrew the locking parts and anti-loosening bolts. The dust baffle can be removed for cleaning or replacement. Multiple dust baffles are set up for backup, which helps to shorten downtime and avoids excessive delays in processing. The electric cylinder controls the valve plate switch, which can automatically discharge the dust in the dust collection box, making it convenient to use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figure 1-5 This utility model provides a technical solution: an energy-saving electrostatic dust removal device with integrated settling function, including an electrostatic dust collector 1, which cleans dust in flue gas and reduces dust emissions. The electrostatic dust collector 1 is connected to an air inlet pipe 6, which is connected to a housing 8. A motor 7 is installed on the surface of the housing 8, and the output shaft of the motor 7 is inserted into the housing 8. The motor 7 can adjust its speed, so as to change the power of the motor 7 according to the flow rate of the flue gas, thereby adjusting the speed of the dust baffle 17.

[0029] The clip bracket 18 is connected to the output shaft of the motor 7. A dust baffle 17 is installed on the clip bracket 18. The output shaft of the motor 7 is fixed to the dust baffle 17 by a locking member 16. The locking member 16 is screwed to the output shaft and holds the dust baffle 17, which can improve the stability of the dust baffle 17 installation.

[0030] The dust collection box 9 is connected to the lower surface of the outer shell 8. A valve is installed at the outlet of the dust collection box 9. When the valve is closed, it can prevent flue gas from leaking from the dust collection box 9. When the valve is opened, it can discharge dust. The dust-laden flue gas enters the dust baffle 17 and the outer shell 8. Some of the dust falls into the dust collection box 9 after colliding with the dust baffle 17. This can intercept large dust particles and prevent them from washing away the electrodes inside the electrostatic precipitator 1, thus ensuring the dust removal effect of the electrostatic precipitator 1, extending the life of the electrostatic precipitator 1, and reducing the cost of flue gas treatment.

[0031] In this embodiment, as Figure 1 As shown, the electrostatic precipitator 1 is connected to a first horn tube 2 and a second horn tube 3 on both sides. The first horn tube 2 and the second horn tube 3 are equipped with flanges 4, which are convenient for connection. The air inlet pipe 6 is connected to the second horn tube 3. A connecting pipe 5 is provided in the middle of the surface of the outer shell 8. The connecting pipe 5 is connected to the pipeline for conveying flue gas and sends the flue gas into the dust collection box 9.

[0032] In this embodiment, as Figure 2As shown, the outer casing 8 is equipped with a maintenance plate 12, which seals the outer casing 8. The maintenance plate 12 is opened to maintain the dust baffle 17. Multiple dust baffles 17 are provided. If the dust baffle 17 that comes into contact with dust first is deformed or damaged, the dust baffles 17 behind it can still intercept the dust. The dust baffle 17 can be replaced by removing the maintenance plate 12.

[0033] In this embodiment, as Figure 2 and Figure 4 As shown, both the outer shell 8 and the inspection plate 12 are fixedly connected with connecting ears 15. The connecting ears 15 have screw holes and are screwed with bolts. Multiple connecting ears 15 and bolts are provided to ensure the stability of the connection.

[0034] In this embodiment, as Figure 5 As shown, the card holder 18 has a plug slot 19, and the dust baffle 17 is inserted into the plug slot 19. When removing or installing the dust baffle 17, the dust baffle 17 can be pulled out directly, which simplifies the operation and makes subsequent maintenance more convenient.

[0035] In this embodiment, as Figure 5 As shown, the snap-fit ​​bracket 18 is screwed with an anti-loosening bolt 20, which passes through the dust baffle 17. This can prevent the dust baffle 17 from separating from the snap-fit ​​bracket 18 due to large centrifugal force, ensuring that the dust baffle 17 is installed stably and will not have any abnormal movement problems.

[0036] In this embodiment, as Figure 3 As shown, the valve includes a frame 10, in which a valve plate 13 is installed. An electric cylinder 11 connected to the valve plate 13 is installed on the frame 10. The electric cylinder 11 can work periodically to control the opening and closing of the valve plate 13 and can periodically discharge dust from the dust collection box 9. A level gauge can be installed on the upper surface of the dust collection box 9 to detect the amount of dust inside the dust collection box 9. When the dust accumulates to a certain height, it can provide a signal to start the electric cylinder 11 to prevent excessive dust accumulation.

[0037] In this embodiment, as Figure 5 As shown, the inner wall of the frame 10 has a sliding groove 14, and the valve plate 13 slides in the sliding groove 14 to improve the stability of the valve plate 13 operation, prevent the valve plate 13 from falling, and improve the smoothness of valve opening and closing.

[0038] Specifically, during use, the flue gas containing dust enters the outer casing 8 through the connecting pipe 5. The output shaft of the motor 7 drives the clamping frame 18 and the dust baffle 17 to rotate. Large dust particles collide with the dust baffle 17 and are intercepted. Then, the large dust particles fall downwards and fall from the outer casing 8 into the dust collection box 9. The flue gas after the large dust particles are removed enters the electrostatic precipitator 1 through the air inlet pipe 6 for dust removal again.

[0039] When the flue gas flows in the outer casing 8, the dust baffle 17 rotates in the same direction as the flue gas flow to prevent the dust baffle 17 from blocking the flow of the flue gas and to maintain a stable flue gas flow rate. The increased rotation speed of the dust baffle 17 can assist the flow of the flue gas without excessively affecting the pressure of the flue gas pipeline. The flue gas flow rate can be maintained without relying on the fan to significantly increase its power, thus indirectly reducing energy consumption.

[0040] When the dust baffle 17 rotates, it generates centrifugal force, which throws large dust particles onto the inner wall of the outer casing 8. With the blocking effect of the dust baffle 17, large dust particles enter the dust collection box 9. Large dust particles that are not easily attached to the dust baffle 17 are reduced, thus reducing the frequency of maintenance.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
