Description

Technical Field

[0001] This invention relates to an electrostatic cyclone composite separation air purification device, and more particularly to an electrostatic cyclone composite filtration air purification device. Background Technology

[0002] Electrostatic precipitators and cyclone separators are commonly used air purification technologies, both of which can effectively remove particulate pollutants from the air under specific operating conditions. However, when the incoming airflow velocity is high, electrostatic precipitators experience two main problems: firstly, the electrostatic module charges the air particles, reducing their efficiency; secondly, the rapid movement of pollutant particles prevents the electrostatic module from efficiently adsorbing air particles, resulting in a significant decrease in operating efficiency.

[0003] Conversely, cyclone separation technology also has significant drawbacks: at low wind speeds, the centrifugal force generated when air particles pass through the cyclone tube is reduced, which prevents particles from passing through the gap between the inlet and outlet pipes, resulting in a significant reduction in particulate matter separation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an air purification device that combines electrostatic dust removal and cyclone separation filtration. By combining the field electrolysis module with the cyclone separation module, the problem that the efficiency of electrostatic dust removal technology drops significantly at high incoming airflow velocities and the particulate matter separation efficiency of cyclone separation technology drops significantly at low airflow velocities is solved, thereby achieving stable and efficient filtration performance of the air purification device at different airflow velocities.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An electrostatic cyclone composite separation air purification device includes a housing, a power supply, and a dust extraction fan. The housing is located at the air inlet, and the power supply is disposed inside the housing. The device further includes an electrostatic module and a cyclone separation module. The electrostatic module includes a flow guide plate and a conductive needle plate. The flow guide plate has flow guide holes distributed on it, and the conductive needle plate has needle structures arranged through the flow guide holes. The cyclone separation module is configured as a spliced ​​structure, consisting of a conductive inlet plate, a conductive intermediate plate, and an outlet plate arranged sequentially, with the outlet plate being an insulator. The conductive inlet plate has an air inlet, front blades, and a positioning center cone. The conductive intermediate plate includes rear blades and a positioning center cone hole. The outlet plate has an outlet pipe. The pipe walls of the conductive inlet plate and the conductive intermediate plate are spliced ​​to form a cavity. The front blades and the rear blades are connected in series to form cyclone tube blades. The power supply is connected to the electrostatic module, the conductive inlet plate, and the conductive intermediate plate.

[0007] The aforementioned electrostatic cyclone composite separation air purification device further includes a micro-electrostatic module, which consists of gaps for passing air particles and electrodes, with the electrodes being alternately arranged in the gaps; the electrodes are connected to the power source.

[0008] In the aforementioned electrostatic cyclone composite separation air purification device, the positioning center cone head is fitted with the positioning center cone hole.

[0009] In the aforementioned electrostatic cyclone composite separation air purification device, the rotation angle of the front blades is less than 90 degrees.

[0010] In the aforementioned electrostatic cyclone composite separation air purification device, the rotation angle of the rear blades is less than 90 degrees.

[0011] In the aforementioned electrostatic cyclone composite separation air purification device, the conductive inlet plate, the conductive intermediate plate, and the outlet plate are coaxially mounted.

[0012] This invention discloses an electrostatic cyclone composite separation air purification device. By configuring the cyclone tube blades into two parts, a front blade and a rear blade, the combined blades of the double-layer cyclone tubes can rotate at an angle of nearly 180 degrees when the rotation angle of each layer of cyclone tube blades is less than 90 degrees. This design saves costs, is convenient in process, simple in structure, and easy to install. In the structure of this electrostatic cyclone composite separation air purification device, the rotation angle of the cyclone tube blades in the cyclone separation module is the sum of the rotation angles of the front blade and the rear blade. This large-angle rotation can effectively increase the air rotation speed, and at the same time increase the radial and tangential velocities of foreign objects, thereby achieving efficient separation of foreign objects entering the device.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0020] Please refer to Figure 1-4 The present invention discloses an electrostatic cyclone composite separation air purification device, comprising a housing 1, a power supply 2, and a dust extraction fan 3. The housing 1 is located at the air inlet, and the power supply is disposed inside the housing 1. The device further includes an electrostatic module 4 and a cyclone separation module 5. The electrostatic module 4 includes a flow guide plate 41 and a conductive needle plate 42. The flow guide plate 41 has flow guide holes 411 distributed on it, and the conductive needle plate has needle structures 421 arranged therethrough, the needle structures 421 penetrating the flow guide holes 411. The cyclone separation module 5 consists of a conductive inlet plate 51, a conductive intermediate plate 52, and an outlet plate 53. 3. Sequential arrangement: The conductive inlet plate 51 is provided with an air inlet 511, a front blade 512, and a positioning center cone 513; the conductive intermediate plate 52 includes a rear blade 521 and a positioning center cone hole 522; the outlet plate 53 is provided with an outlet pipe 531; the pipe walls of the conductive inlet plate 51 and the conductive intermediate plate 52 are spliced ​​to form a cavity; the front blade 512 and the rear blade 521 are connected in series to form a cyclone tube blade; the power supply 2 is connected to the field power module 4, the conductive inlet plate 51, and the conductive intermediate plate 52 respectively.

[0021] The present invention discloses an electrostatic cyclone composite separation air purification device. The device uses an electric field module 4 to charge air particles. When the particles pass through the cyclone separation module 5, they move towards the cyclone tube wall under the action of centrifugal force and electrostatic adsorption, and are separated through the gap between the cyclone tube wall and the outlet pipe 531. Finally, they are discharged by the dust extraction fan 3.

[0022] To further improve air purification efficiency and achieve better air purification results, the aforementioned electrostatic cyclone composite separation air purification device further includes a micro-electrostatic module 6. The micro-electrostatic module 6 consists of gaps 61 for the passage of airborne particles and electrode plates 62, with the electrode plates 62 alternately arranged within the gaps 61. The electrode plates 62 are connected to the power supply 2. Residual particles after dual filtration by the field electrostatic module 4 and the cyclone separation module 5 can be adsorbed by the electrode plates 62 when passing through the gaps 61 of the micro-electrostatic module 6, thereby achieving the purification purpose.

[0023] pass Figure 5 and Figure 6It can be seen that in the cyclone separation module 5 of the electrostatic cyclone composite separation air purification device of the present invention, the cyclone tube system is a combined cyclone tube, which is composed of a double-layer structure of front blade 512 and rear blade 521 connected in series. During use, the rotation angle of the blades of the double-layer structure cyclone tube is the sum of the rotation angle of the front blade 512 and the rotation angle of the rear blade 521. The sum of the two is a large angle close to 180 degrees. Such a large angle rotation can increase the radial velocity and tangential velocity of foreign objects in the air passing through the separator, thereby achieving efficient separation of foreign objects.

[0024] As a further improvement, in the aforementioned electrostatic cyclone composite separation air purification device, the conductive inlet plate 51, the conductive intermediate plate 52, and the outlet plate 53 are coaxially mounted. Coaxial mounting helps maintain stable pressure drop in the cyclone separation module 5, thereby improving separation efficiency and extending the equipment's service life.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the scope of the patent application of the present invention. Therefore, all equivalent structural changes made based on the description and illustrations of the present invention are included within the protection scope of the present invention.
