Description

Technical Field

[0001] The utility model relates to a split discharge electrode for an electrostatic collector and the electrostatic collector, belonging to the field of electrode structures. Background Art

[0002] Electrostatic collectors are widely used in flue gas analysis, industrial exhaust purification, dust control and other fields. They use electrostatic force to separate suspended particles and droplets from airflow. Corona discharge is generated by the metal discharge electrode under the action of high DC voltage, so that the dust particles in the dust-laden gas are charged and migrate to the dust collecting electrode under the action of the electric field force, thereby achieving gas purification.

[0003] In existing electrostatic collectors, the collecting electrode is usually tubular, with the discharge electrode arranged on the center line of the collecting electrode and one end cantilevered inside the collecting electrode. The electrostatic collector also includes an electrode fixing tube for fixing the discharge electrode and a collecting electrode fixing tube for fixing the collecting electrode. The electrode fixing tube is located inside the collecting electrode fixing tube. A through hole is provided in the electrode fixing tube, one end of which is for the discharge electrode to be inserted into, and the other end is for the power cord to be inserted into. The power cord contacts the discharge electrode to charge the discharge electrode, forming an electric field inside the collecting electrode. A circular hole is provided on the side of the collecting electrode fixing tube for connecting to the gas outlet pipe. One end of the collecting electrode is fixed to the collecting electrode fixing tube, and the other end of the collecting electrode is open to allow flue gas to enter. Particles such as tar in the flue gas will be charged in the electric field inside the collecting electrode and move toward the collecting electrode, thereby filtering out the tar and achieving flue gas purification. The inner hole of the collecting electrode and the circular hole are connected to form a gas flow channel, and the purified flue gas can be discharged through the gas flow channel.

[0004] Because the discharge electrode is exposed to flue gas, tar will adhere to its surface after repeated use, preventing it from functioning properly. Therefore, regular maintenance and replacement of the discharge electrode are necessary to ensure the electrostatic collector's impurity removal effectiveness. However, existing discharge electrodes are typically integrated. To disassemble the discharge electrode, the entire electrode must be removed, cleaned, and then inserted into the discharge electrode fixing tube. Due to the interference fit between the discharge electrode and the discharge electrode fixing tube, the friction during removal and insertion is high, making disassembly and assembly extremely inconvenient and inconvenient for routine maintenance and replacement. Utility Model Content

[0005] The purpose of the utility model is to provide a split discharge electrode for an electrostatic collector and an electrostatic collector, so as to solve the problem that the discharge electrode in the existing electrostatic collector needs to be pulled out or plugged in as a whole during disassembly and assembly, and the friction force during pulling out or plugging is large, which makes disassembly and assembly inconvenient.

[0006] To achieve the above-mentioned purpose, the split discharge electrode for the electrostatic collector in the present invention adopts the following technical solutions:

The electrode body also includes a threaded connection section, and a threaded matching section adapted to the threaded connection section is provided on the electrode seat, so that the electrode seat and the electrode body are detachably connected. Therefore, during installation, the electrode seat is fixed in the electrode fixing tube, and the electrode body is screwed and installed on the electrode seat. When daily maintenance and replacement are required, it is only necessary to unscrew the electrode body without removing the electrode seat. Moreover, the electrode seat is threadedly connected to the electrode body, and the friction force is small when screwing, so that the disassembly of the discharge body is effortless, thereby realizing simple and convenient disassembly and assembly of the discharge electrode.

[0009] Furthermore, the electrode body also includes a square rod section for the operating tool to screw and apply force, and the square rod section is located between the threaded connection section and the discharge section.

[0010] Furthermore, the square rod segment is a quadrangular prism.

[0022] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0023] In response to the technical problems existing in the prior art, the basic technical concept of the present invention is: the discharge electrode in the electrode collector is set as a separately connected electrode seat and an electrode body, the electrode seat and the electrode body are threadedly connected, and the electrode seat is fixed on the electrode fixing tube of the electrostatic collector. During daily maintenance and replacement, it is only necessary to unscrew the electrode body without removing the electrode seat, and the friction force of screwing the electrode body is small, thereby realizing simple and convenient disassembly of the discharge electrode.

[0024] Embodiment of the split discharge electrode for electrostatic collector in the utility model:

[0025] like Figure 1 As shown, the split discharge electrode for the electrostatic collector includes an electrode holder 1 and an electrode body 3 that are separately connected. In this embodiment, the discharge electrode is cylindrical as a whole and has a length of 8 cm, wherein the electrode holder 1 is 3 cm long and 0.8 cm in diameter, and the discharge area of ​​the electrode body 3 is 5 cm long and 5 mm in diameter. Such dimensions can ensure sufficient electric field strength and mechanical strength, while also taking into account manufacturing costs and process feasibility. The electrode body 3 is made of the same material as the electrode holder 1, and pure copper or other corrosion-resistant conductive materials can be selected. The electrode holder 1 can be in contact with and connected to the power line, and transfer current to the electrode body 3, so that the electrode body 3 can generate corona current.

[0026] The electrode holder 1 is provided with a fixing structure for fixing to the electrode fixing tube of the electrostatic collector. In this embodiment, a sealing ring 2 is provided near one end of the electrode holder 1, and an annular groove (not marked in the figure) is provided at a position corresponding to the sealing ring 2 on the electrode holder 1. The sealing ring 2 and the annular groove constitute a fixing structure. The preferred size of the annular groove is 3 mm deep and 4 mm wide, so that the sealing ring 2 can be sleeved in the groove. When in use, the electrode holder 1 needs to be inserted into the electrode fixing tube for the first installation. The sealing ring 2 is interference fit with the inner wall of the electrode fixing tube to ensure that the electrode holder 1 is installed firmly and reliably. The electrode holder 1 does not need to be disassembled for subsequent use to improve the convenience of installation.

[0027] The electrode holder 1 also includes a threaded fitting section (not shown in the figure), which is located near the end of the sealing ring 2. In the present embodiment, the threaded fitting section is an internal threaded hole. The electrode body 3 includes a threaded connection section 31 that cooperates with the threaded fitting section. The threaded connection section 31 has an external thread, so that the electrode body 3 and the electrode holder 1 can be detachably connected through the threaded connection section 31 and the threaded fitting section. When in use, the discharge holder 1 is fixed in the electrode fixing tube by a fixing structure, and the electrode body 3 is located in the dust collecting electrode to generate an electric field. When maintenance and replacement are required, it is only necessary to unscrew the electrode body 3, and then screw the electrode body 3 back onto the electrode holder 1 after the operation is completed. Installation and disassembly are simple and convenient, which improves the convenience of maintenance.

[0028] The electrode body 3 also includes a discharge segment 33 for discharging. The discharge segment 33 is the discharge area of ​​the electrode body 3, that is, the length of the discharge segment 33 is 5 cm. In this embodiment, the discharge segment 33 is cylindrical, so it is not easy to wear and deform. The electrode body 3 also includes a square rod segment 32. The square rod segment 32 is located between the discharge segment 33 and the threaded connection segment 31. When the electrode body 3 is screwed, the square rod segment 32 provides a force application position for the operating tool. In this embodiment, the square rod segment 32 is set as a quadrangular prism. The cross-sectional area of ​​the square rod segment 32 is larger than the cross-sectional area of ​​the round rod segment 33 and the threaded connection segment 31. When cleaning and maintenance are required, the operator can unscrew the electrode body 3 through the square rod segment 32.

[0029] During use, the electrode holder 1 is fixed in the electrode fixing tube, and the discharge segment 33 is suspended in the dust collecting electrode of the electrostatic collector. The electrode holder 1 is connected to the power supply and transmits current to the discharge segment 33, so that the discharge segment 33 can form an electric field in the dust collecting electrode. After repeated use, when tar adheres to the surface of the discharge electrode and makes it unable to work properly, the discharge electrode needs to be cleaned and maintained. In this case, simply unscrew the electrode body 3 from the electrode holder 1 and wipe it with a solvent such as methanol. After the electrode body 3 is dry, it can be screwed back onto the electrode holder 1 to complete the maintenance operation. It is simple, convenient, and effortless.

[0030] In other embodiments, when setting the threaded connection between the electrode body and the electrode holder, the threaded connection section on the electrode body can be set as an internal threaded hole, and the threaded matching section on the electrode holder can be set as an external thread.

[0031] In other embodiments, when setting the shape of the square rod segment, the square rod segment can be set to be a hexagonal prism or an octagonal prism.

[0032] In other embodiments, the square rod segment may not be provided. In this case, when the electrode body needs to be unscrewed, force may be applied directly to the discharge segment.

[0033] In other embodiments, when setting the fixing structure on the electrode holder, the annular groove and the sealing ring may not be set. In this case, the electrode holder can be directly fixed in the electrode fixing tube by interference fitting, that is, the outer peripheral surface of the electrode holder is directly interference fit with the inner hole wall of the electrode fixing tube. In this case, the fixing structure is the outer peripheral surface of the electrode holder.

[0034] An embodiment of the electrostatic collector in the present invention: The electrostatic collector includes an electrode fixing tube and a discharge electrode fixed on the electrode fixing tube. The structure of the discharge electrode is the same as the structure of the split discharge electrode in the above-mentioned split discharge electrode embodiment for the electrostatic collector, and will not be repeated.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
