Description

Technical Field

[0001] This utility model belongs to the field of cyclone separator technology, specifically relating to an electrostatic dust removal mechanism for a cyclone separator. Background Technology

[0002] With increasing environmental awareness and stricter emission standards, gas-solid separation technology is being used more and more widely in the industrial field. Cyclone separators, as a common type of gas-solid separation equipment, utilize the centrifugal force generated by rotating airflow to separate particulate matter from the airflow.

[0003] However, traditional cyclone separators suffer from low separation efficiency when handling small-diameter particles due to the weak inertial force of these particles, making it difficult to meet stringent environmental protection requirements. The low separation efficiency of traditional cyclone separators for small-diameter particles leads to high emission concentrations, failing to meet environmental regulations. Furthermore, existing cyclone separators have a relatively simple structure, failing to fully utilize multiple separation mechanisms such as rotating airflow and electrostatic fields.

[0004] To address the shortcomings of existing technologies, an electrostatic dust removal mechanism for cyclone separators is proposed. Utility Model Content

[0005] The present invention aims to solve the technical problem of low separation efficiency of cyclone separators when processing small-diameter particles due to their low inertial force.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrostatic dust removal mechanism for a cyclone separator includes a cyclone separator body, an electrostatic generator, electrostatic electrodes, and a conductive layer.

[0008] The cyclone separator body includes a straight cylinder, an air inlet pipe, an air outlet pipe, and a conical cylinder. The bottom of the conical cylinder is equipped with a collection device for collecting impurities.

[0009] An electrostatic generator is installed at the air inlet pipe of the cyclone separator body to generate an electrostatic field;

[0010] The electrostatic electrode is installed inside the conical cylinder of the cyclone separator body and connected to the electrostatic generator to adsorb charged particles.

[0011] A conductive layer is coated on the inner wall of the conical cylinder of the cyclone separator body and connected to the electrostatic electrode; it is used to enhance the adsorption effect of the electrostatic field.

[0012] The electrostatic generator produces an electrostatic field at the air inlet duct, which charges the dust-laden gas particles. The particles move toward the conductive layer on the inner wall of the conical cylinder and are adsorbed onto the conductive layer. The particles fall into the collection device due to gravity.

[0013] Preferably, the air inlet pipe is located on the side wall of the straight cylinder, the air outlet pipe is located on the upper end face of the straight cylinder, and the conical cylinder is located at the bottom of the straight cylinder.

[0014] Preferably, the conical cylinder includes an upper part that connects to the straight cylinder and a lower part that connects to the collecting device.

[0015] Preferably, the lower half includes an inner cone that connects to the upper half and the collecting device, and an outer cone that surrounds the outer side of the inner cone. An electrostatic electrode is installed in the cavity formed by the inner and outer cones, and a conductive layer is coated on the inner surface of the inner cone.

[0016] The conical cylinder is divided into an upper and a lower section. The upper section connects to the straight cylinder, and the lower section connects to the collection device. This design facilitates modular production and installation, as well as maintenance and replacement.

[0017] Preferably, the inner cone is provided with flanges A at its upper and lower ends, which are connected to the upper half and the collecting device. The outer cone includes a left half and a right half. The mating surfaces of the left and right halves are provided with flanges. The left and right halves are fixed together by bolts that pass through the flanges. The upper and lower ends of the left and right halves are provided with flanges B. The flanges B on the left and right halves are connected to flanges A by flange bolts.

[0018] The inner cone is equipped with flanges A at both the upper and lower ends, and the left and right halves of the outer cone are connected by flange B. This flange connection method facilitates the assembly, disassembly and maintenance of the electrostatic electrode.

[0019] Preferably, the outer side of the air inlet duct is fitted with a clamp that is fixedly connected to the mounting panel, and the electrostatic generator is fixedly installed on the mounting panel.

[0020] Preferably, the cyclone separator body is equipped with a support frame. The support frame enhances the stability of the cyclone separator and avoids structural damage caused by vibration and other factors.

[0021] Compared with the prior art, the technical effects and advantages of this utility model are:

[0022] This cyclone separator's electrostatic dust removal mechanism creates an electrostatic field by introducing an electrostatic generator and electrostatic electrodes into the cyclone separator. This charges the particles, thereby enhancing their centrifugal separation effect in the rotating airflow. The coating of a conductive layer further improves the uniformity of the electrostatic field and the adsorption efficiency of the particles, effectively increasing the separation efficiency for fine particles.

[0023] The conical cylinder design utilizes modular production, facilitating installation and maintenance. Furthermore, the structure of the inner and outer conical cylinders helps enhance the concentration and effectiveness of the electrostatic field, making the entire separation process more efficient.

[0024] By incorporating the above content, the electrostatic precipitator mechanism of the cyclone separator makes up for the shortcomings of traditional cyclone separators in handling fine particulate matter, significantly improves separation efficiency, reduces emission concentration, meets stricter environmental protection requirements, and has good practicality and economic benefits.

[0031] 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.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses an electrostatic dust removal mechanism for a cyclone separator, including a cyclone separator body 1, an electrostatic generator 2, an electrostatic electrode 3, and a conductive layer 4.

[0034] The cyclone separator body 1 includes a straight cylinder 5, an inlet pipe 6, an outlet pipe 7, and a conical cylinder 8. The bottom of the conical cylinder 8 is equipped with a collection device 9 for collecting impurities. The inlet pipe 6 is located on the side wall of the straight cylinder 5, the outlet pipe 7 is located on the upper end face of the straight cylinder 5, and the conical cylinder 8 is located at the bottom of the straight cylinder 5. Side wall air intake helps to form a more efficient rotating airflow, making it easier for particulate matter to separate during rotation within the cyclone separator. The outlet pipe 7's location on the upper end face facilitates the optimization of the airflow organization inside the cyclone separator, reducing turbulence and improving the quality of the outlet air.

[0035] A bracket 12 is provided on the cyclone separator body 1. The bracket 12 enhances the stability of the cyclone separator and avoids structural damage caused by vibration and other reasons. It facilitates the installation and fixing of the cyclone separator, ensuring that it will not move or tilt during use, thereby guaranteeing the dust removal effect.

[0036] An electrostatic generator 2 is installed at the air inlet pipe 6 of the cyclone separator body 1 to generate an electrostatic field. A pipe clamp 10, which is fixedly connected to the mounting panel 11, is fitted onto the outer side of the air inlet pipe 6. The electrostatic generator 2 is fixedly installed on the mounting panel 11. The design of the pipe clamp 10 and the mounting panel 11 makes the installation of the electrostatic generator 2 more secure and facilitates maintenance and replacement. This helps ensure the stability and safety of the overall structure of the cyclone separator.

[0037] The electrostatic electrode 3 is disposed inside the conical cylinder 8 of the cyclone separator body 1 and connected to the electrostatic generator 2 for adsorbing charged particles; the conductive layer 4 is coated on the inner wall of the conical cylinder 8 of the cyclone separator body 1 and connected to the electrostatic electrode 3 for enhancing the adsorption effect of the electrostatic field.

[0038] The electrostatic generator 2 generates an electrostatic field at the air inlet duct 6, which charges the dust-laden gas particles. The particles move toward the conductive layer 4 on the inner wall of the conical cylinder 8 and are adsorbed onto the conductive layer 4. The particles fall into the collection device 9 due to gravity.

[0039] When dust-laden gas enters the cyclone separator body 1, the electrostatic generator 2 generates an electrostatic field, charging the particulate matter. Under the influence of this electrostatic field, the charged particles move towards the conductive layer 4 on the inner wall of the conical cylinder 8 and are adsorbed onto it. As the particles accumulate, when a certain quantity is reached, they fall into the collection device 9 due to gravity, thus achieving effective separation of fine particulate matter. By introducing an electrostatic dust removal mechanism into the cyclone separator, the separation efficiency of fine particulate matter is effectively improved, the emission concentration is reduced, and stricter environmental protection requirements are met. Furthermore, this mechanism has a simple structure, is easy to install, and has low maintenance costs, demonstrating good practicality and economic benefits.

[0040] The conical cylinder 8 includes an upper half 81 that connects to the straight cylinder 5 and a lower half 82 that connects to the collecting device 9.

[0041] The lower half 82 includes an inner cone 8201 that connects to the upper half 81 and the collecting device 9, and an outer cone 8202 that surrounds the outer side of the inner cone 8201. An electrostatic electrode 3 is installed within the cavity formed by the inner and outer cones 8201. A conductive layer 4 is coated on the inner surface of the inner cone 8201. Dividing the cone 8 into an upper half 81 and a lower half 82, with the upper half 81 connecting to the straight cylinder 5 and the lower half 82 connecting to the collecting device 9, facilitates modular production and installation, as well as maintenance and replacement. The structure of the inner and outer cones 8201 and 8202 helps enhance the concentration and effectiveness of the electrostatic field because the electrostatic electrode 3 is installed within the cavity formed by the inner and outer cones 8201 and 8202, allowing for more effective adsorption of charged particles. The conductive layer 4 coated on the inner surface of the inner cone 8201 helps improve the uniformity of the electrostatic field and the adsorption efficiency of particles.

[0042] The inner cone 8201 has flanges A8203 at its upper and lower ends, which are connected to the upper half 81 and the collecting device 9, respectively. The outer cone 8202 includes a left half 8204 and a right half 8205. The mating surfaces of the left half 8204 and the right half 8205 are provided with flanges 8206. The left half 8204 and the right half 8205 are fixed together by bolts passing through the flanges 8206. The upper and lower ends of the left half 8204 and the right half 8205 are provided with flanges B8207, which are connected to flanges A8203 by flange bolts.

[0043] The inner cone 8201 has flanges A8203 at both ends, and the left half 8204 and right half 8205 of the outer cone 8202 are connected by flange B8207. This flange connection method facilitates the assembly, disassembly, and maintenance of the electrostatic electrode 3, improving the reliability and stability of the structure. The flange plate 8206 and the bolt fixing method make the structure of the cone 8 more robust, reducing structural damage caused by vibration and other reasons.

[0044] The electrostatic precipitator mechanism of this cyclone separator utilizes the centrifugal force generated by the rotating airflow to separate particulate matter from the airflow. Larger particles, due to inertia, are thrown against the wall of the cyclone separator and then slide down the wall into the collection device 9 at the bottom of the conical cylinder 8. When the electrostatic generator 2 generates an electrostatic field, the particles become charged as they enter the cyclone separator through the inlet pipe 6. Due to the presence of the electrostatic field, the charged particles are subjected to an electric field force, enhancing their centrifugal separation effect in the rotating airflow. The electrostatic electrode 3 is located on the inner wall of the conical cylinder 8 of the cyclone separator and is connected to the electrostatic generator 2. Under the action of the electric field force, the charged particles are adsorbed onto the electrode, thereby achieving separation. The conductive layer 4 is coated on the inner wall of the conical cylinder 8 of the cyclone separator and connected to the electrostatic electrode 3, which can further enhance the adsorption effect of the electrostatic field and help capture and separate smaller diameter particles.

[0045] In this way, even small-diameter particles can be effectively separated in the cyclone separator. The introduction of the electrostatic field and electrostatic electrode 3 compensates for the shortcomings of the cyclone separator in handling fine particles, resulting in a significant improvement in the separation efficiency of the entire system.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
