Description

Technical Field

[0001] This application relates to the field of electrostatic precipitator technology, specifically to an electrostatic precipitator device for reducing dust escape and emissions. Background Technology

[0002] With the acceleration of industrialization, air pollution has become increasingly serious. Dust emissions are one of the major pollutants, affecting not only air quality but also posing a threat to human health. Therefore, developing efficient dust treatment devices has become a research hotspot in the environmental protection field.

[0003] Existing electrostatic precipitators suffer from reduced dust collection efficiency due to the large amount of dust collected on the collecting plates. This results in the plates being unable to collect dust efficiently, and the collected dust escaping as it is resuspended by the airflow. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an electrostatic precipitator for reducing dust escape emissions. It features the ability to clean and centrally collect dust on the collecting plates, preventing the plates from becoming inefficient at collecting dust and preventing the large amount of dust collected on the plates from being resuspended by the airflow, thus avoiding dust escape during the dust removal process and improving dust removal efficiency. This solves the problem in existing electrostatic precipitators where a large amount of dust collected on the collecting plates affects the collection efficiency, leading to the plates becoming inefficient at collecting dust and the collected dust escaping due to resuspension by the airflow, resulting in a decrease in overall dust removal efficiency.

[0005] To achieve the aforementioned goals of cleaning and concentrating the dust collected on the dust collecting plates, preventing the plates from becoming inefficient at collecting dust, and preventing the large amount of dust collected on the plates from being resuspended by the airflow, thus avoiding dust escape during the dust removal process and improving dust removal efficiency, this application provides the following technical solution: an electrostatic precipitator for reducing dust escape emissions, comprising a housing, with two support plates disposed at the bottom and top of the inner wall of the housing, and multiple dust collecting plates disposed between the two support plates, with multiple corona wires disposed between every two adjacent dust collecting plates. The two ends of the halo line are located on the inner side of two support plates. One side of each of the multiple dust collection plates is located on one side of a connecting plate. A push rod is located on the other side of the connecting plate. A push plate is located at one end of the push rod. The outer surface of one side of the push plate is slidably connected to the outer surface of one end of the lever. The inner wall of the other end of the lever is fixedly sleeved on the outer surface of one end of the motor shaft. A discharge port that runs vertically through the bottom of the housing is provided. A collection hopper is provided at the bottom of the housing. The inside of the collection hopper is connected to the inside of the housing through the discharge port at the bottom of the housing. An air inlet and an air outlet are respectively provided at both ends of the housing. A negative pressure fan is provided at the air outlet at one end of the housing.

[0006] The above solution utilizes a motor to drive a lever that strikes and moves a push plate. This causes the push plate, through a push rod and connecting plate, to vibrate and shake the dust collection plate. The vibration and shaking of the dust collection plate dislodge the dust adhering to it, which falls into the collection hopper below. This effectively cleans and collects the dust on the dust collection plate, preventing it from becoming inefficient and ensuring that the plate continues to collect dust efficiently. Furthermore, it prevents the large amount of dust collected on the plate from being resuspended by airflow, thus avoiding dust escape during the dust removal process and improving overall dust removal efficiency.

[0007] Furthermore, the corona wire is spirally arranged, and the material of the corona wire is tungsten wire.

[0008] Through the above scheme, the spiral corona wire can increase its discharge area and improve ionization efficiency, so that more dust particles can be charged and captured by the dust collection plate. At the same time, the tungsten wire material has good conductivity and high temperature resistance, which can maintain a stable discharge effect during long-term operation and ensure the efficient operation of the dust removal device.

[0009] Furthermore, an insulating plate is provided on the opposite side of the two outermost dust collecting plates, and the two insulating plates are respectively located between the two outermost dust collecting plates and the two sides of the inner wall of the shell.

[0010] The above solution prevents electrical short circuits between the dust collection plates and the inner wall of the housing, ensuring the safe operation of the dust removal device.

[0011] Furthermore, the two ends of the plurality of dust collection plates are disposed on one side of the two fixed plates, and the two fixed plates are each provided with a connecting frame corresponding to the number of dust collection plates by means of a fixing frame on the side away from the dust collection plates. The inner wall of the middle of the plurality of connecting frames is slidably disposed on the outer surface of the middle of the plurality of positioning rods, and the plurality of positioning rods are respectively disposed at both ends of the support plate.

[0012] The above scheme ensures the stability of the dust collection plates during vibration and shaking by cooperating with the connecting frame and positioning rod. The fixing plate can connect multiple dust collection plates together to prevent deformation or damage caused by uneven force.

[0013] Furthermore, a spring is provided on the side of the connecting frame near the support plate, with one end of the spring located at one end of the support plate.

[0014] The above solution allows the spring to further increase the stability of the dust collection plate during vibration and shaking. The spring also enables the dust collection plate to quickly return to its original position after vibration, ensuring the stability and continuity of dust removal efficiency.

[0015] Furthermore, the support plate is made of high-strength ceramic material.

[0016] Through the above scheme, the high-strength ceramic material of the support plate has good mechanical strength and high temperature resistance, and can withstand the stress and friction generated by the dust collection plate during vibration. At the same time, the ceramic material also has good insulation properties, which can prevent electrical short circuits and ensure the safe operation of the dust removal device.

[0017] Furthermore, the bottom of the support plate located below the dust collecting plate has multiple discharge ports, which are located below the dust collecting surface of the dust collecting plate.

[0018] The above scheme ensures that the dust falling from the dust collection surface of the dust collection plate can fall smoothly into the collection hopper below.

[0019] Furthermore, the push plate extends downward to the outside of the housing, and a mounting box is provided at the bottom of the housing corresponding to the position of the push plate. The bottom of the inner wall of the mounting box is fixedly connected to the bottom of the motor by a fixing block.

[0020] With the above solution, the gas blown out from the housing is not without high temperature gas. The downward extension of the push plate allows the motor to be positioned below the air duct inside the housing, preventing the high temperature gas from blowing directly onto the motor and causing it to overheat.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This electrostatic precipitator, designed to reduce dust escape emissions, utilizes a motor to drive a lever that strikes and moves a push plate. This push plate, through a push rod and connecting plate, vibrates and shakes the dust collecting plates. The vibration and shaking dislodge dust adhering to the plates, causing it to fall into the collection hopper below. This effectively cleans and collects the dust on the collecting plates, preventing them from becoming inefficient and ensuring efficient dust collection. Furthermore, it prevents the large amount of dust collected on the plates from being resuspended by airflow, thus avoiding dust escape during the dust removal process and improving overall dust removal efficiency.

One side of each of the multiple dust collection plates 3 is provided on one side of a connecting plate 9. A push rod 10 is provided on the other side of the connecting plate 9. A push plate 11 is provided at one end of the push rod 10. The outer surface of one side of the push plate 11 is slidably connected to the outer surface of one end of a lever 12. The inner wall of the other end of the lever 12 is fixedly sleeved on the outer surface of one end of the motor shaft of a motor 13. A discharge port that runs vertically through the bottom of the housing 1 is provided. A collection hopper 14 is provided at the bottom of the housing 1. The interior of the collection hopper 14 is connected to the interior of the housing 1 through the discharge port at the bottom of the housing 1. An air inlet and an air outlet are provided at both ends of the housing 1. A negative pressure fan 17 is provided at the air outlet at one end of the housing 1.

[0034] Please see Figure 5 and Figure 6 The corona wire 4 is spirally arranged and made of tungsten wire. The spiral shape of the corona wire 4 can increase its discharge area and improve ionization efficiency, so that more dust particles can be charged and captured by the dust collection plate 3. At the same time, the tungsten wire material has good conductivity and high temperature resistance, which can maintain a stable discharge effect during long-term operation and ensure the efficient operation of the dust removal device.

[0035] Please see Figure 3 , Figure 5 and Figure 7 Insulating plates 18 are provided on the opposite sides of the two outermost dust collecting plates 3. The two insulating plates 18 are located between the two outermost dust collecting plates 3 and the inner wall of the housing 1 on both sides. The insulating plates 18 can prevent electrical short circuits between the dust collecting plates 3 and the inner wall of the housing 1, and ensure the safe operation of the dust removal device.

[0036] Please see Figure 3 and Figure 4 Multiple dust collection plates 3 are positioned at both ends on one side of two fixed plates 7. The two fixed plates 7, away from the dust collection plates 3, are each equipped with a connecting frame 6 corresponding to the number of dust collection plates 3 via a fixing frame. The inner wall of the middle of the multiple connecting frames 6 is slidably mounted on the outer surface of the middle of multiple positioning rods 5. The multiple positioning rods 5 are respectively positioned at both ends of the support plate 2. The cooperation between the connecting frames 6 and the positioning rods 5 can ensure the stability of the dust collection plates 3 during vibration and shaking. The fixed plates 7 can connect the multiple dust collection plates 3 together to prevent the multiple dust collection plates 3 from deforming or being damaged due to uneven force.

[0037] Please see Figure 3 and Figure 4 A spring 8 is provided on the side of the connecting frame 6 near the support plate 2. One end of the spring 8 is located at one end of the support plate 2. The spring 8 can further increase the stability of the dust collection plate 3 during vibration and shaking. The spring 8 can also make the dust collection plate 3 quickly return to its original position after vibration, ensuring the stability and continuity of dust removal efficiency.

[0038] Please see Figure 3 , Figure 4 and Figure 5 The support plate 2 is made of high-strength ceramic material. The high-strength ceramic material of the support plate 2 has good mechanical strength and high temperature resistance, and can withstand the stress and friction generated by the dust collection plate 3 during vibration. At the same time, the ceramic material also has good insulation properties, which can prevent electrical short circuits and ensure the safe operation of the dust removal device.

[0039] Please see Figure 6 and Figure 7 The bottom of the support plate 2 located below the dust collecting plate 3 has multiple discharge ports 15. The discharge ports 15 are located below the dust collecting surface of the dust collecting plate 3. The discharge ports 15 are designed so that the dust falling off the dust collecting surface of the dust collecting plate 3 can fall smoothly into the collection hopper 14 below.

[0040] Please see Figure 1 , Figure 2 and Figure 4 The push plate 11 extends downward to the outside of the housing 1. A mounting box 16 is provided at the bottom of the housing 1 corresponding to the position of the push plate 11. The bottom of the inner wall of the mounting box 16 is fixedly connected to the bottom of the motor 13 by a fixing block. The gas blown out from the housing 1 may contain high temperature gas. The downward extension of the push plate 11 allows the motor 13 to be positioned below the air duct of the housing 1, avoiding the high temperature gas from blowing directly onto the motor 13 and causing the motor 13 to overheat.

[0041] This embodiment of an electrostatic precipitator for reducing dust escape emissions utilizes a motor 13 that drives a lever 12 to strike and move a push plate 11. This causes the push plate 11, through a push rod 10 and a connecting plate 9, to vibrate and shake the dust collecting plate 3. The vibration and shaking of the dust collecting plate 3 shakes off the dust adhering to it, which falls into the collection hopper 14 below. This achieves the goal of cleaning and concentrating the dust collected on the dust collecting plate 3, preventing the dust collecting plate 3 from becoming inefficient in collecting dust, and preventing the large amount of dust collected on the dust collecting plate 3 from being resuspended by the airflow. This avoids dust escape during the dust removal process and improves the efficiency of dust removal.

[0042] The working principle of the above embodiment is as follows: the air inlet at one end of the housing 1 is connected to the air source to be treated, and the air outlet of the negative pressure fan 17 at one end of the housing 1 is connected to the exhaust system. The air source to be treated enters the housing 1 through the air inlet at one end of the housing 1. The negative pressure fan 17 operates to draw the air source to be treated into the housing 1, causing the air source to be carried out through the channel between multiple dust collection plates 3. The corona wire 4 generates a strong electric field, which charges the dust particles in the air. Under the action of the electric field force, the charged dust particles move towards the dust collection plates 3 and adhere to their surface, thus removing dust from the air source. The air source after dust removal is then passed through the negative pressure fan. The exhaust system connected to the machine's air outlet discharges the dust. When a large amount of dust adheres to the dust collection plate 3, the motor 13 operates, driving the lever 12 to rotate. The lever 12 strikes and moves the push plate 11, causing the push plate 11 to vibrate and shake through the push rod 10 and the connecting plate 9. The dust collection plate 3 slides on the positioning rod 5 through the connecting frame 6, and the spring 8 pushes the connecting frame 6, causing the dust collection plate 3 to reciprocate due to inertia. The dust adhering to the dust collection surface of the dust collection plate 3 is shaken off by the vibration and shaking of the dust collection plate 3 and falls into the collection hopper 14 through the discharge port 15 for collection.
