Description

Technical Field

[0001] This utility model belongs to the technical field of electrostatic precipitators for copper smelting, and specifically relates to an insulating support for the top of an electrostatic precipitator. Background Technology

[0002] In copper smelting, the flue gas produced by furnace smelting contains a certain amount of dust. Some furnace types do not have dried raw materials, resulting in high moisture content in the flue gas. In addition, certain elements in some raw materials cause the dust in the flue gas to easily form high resistivity dust, which makes the materials in the flue gas easy to stick together. This leads to a decrease in the insulation performance of 95 porcelain insulators, a decrease in the dust collection efficiency of electrostatic precipitators, and ash accumulation in downstream flue equipment. This increases the difficulty of subsequent chemical processing and seriously affects normal production. Utility Model Content

[0003] To address the problem that flue gas generated during furnace smelting affects the insulation performance of electrostatic precipitators, this utility model provides a top insulation support for electrostatic precipitators, which can ensure timely cleaning of damp dust and ash accumulation inside the top insulation support while ensuring the insulation and sealing of the insulation support.

[0004] This utility model is achieved through the following technical solution: An insulating support for the top of an electrostatic precipitator is provided at the top of the cathode hanging rod of the electrostatic precipitator, and includes a 95-degree ceramic conical sleeve, a corrugated compensator, a sealing gland, and a hot air purging pipe. The 95mm conical ceramic sleeve is fitted onto the top of the cathode hanging rod of the electrostatic precipitator. A hot air inlet is provided on the side of the 95mm conical ceramic sleeve. The hot air inlet is connected to one end of the corrugated compensator, and the other end of the corrugated compensator is connected to the hot air purging pipe. One end of the hot air purging pipe is connected to the hot air main pipe. The sealing cap is located on the top of the 95mm ceramic conical sleeve and is fixed to the extended end of the cathode hanging rod by a nut.

[0005] Preferably, the hot air inlet is located 1-5 cm below the middle of the 95mm ceramic conical sleeve.

[0006] The 95 ceramic conical sleeve has a narrow top and wide bottom structure. The hot air inlet is located in the middle of the sleeve, which can efficiently blow the large space at the bottom of the 95 ceramic conical sleeve. At the same time, the rising hot air can also blow the small space at the top of the 95 ceramic conical sleeve.

[0007] Preferably, the hot air purging pipe is wrapped with insulating material.

[0008] The working principle of this utility model is as follows: This invention involves installing a 95mm ceramic conical sleeve on the outer side of the top of the cathode hanging rod of an electrostatic precipitator to ensure the insulation performance of the cathode hanging rod. Simultaneously, a sealing cap is used at the top of the cathode hanging rod to seal the portion of the rod penetrating the 95mm ceramic conical sleeve, preventing flue gas escape. A hot air inlet is installed on the side of the 95mm ceramic conical sleeve, connected to a corrugated compensator and then to a hot air purging pipe. This allows hot air from the main hot air pipe to be drawn into the 95mm ceramic conical sleeve to purge accumulated dust and ash. The hot air also ensures the interior of the 95mm ceramic conical sleeve remains dry, preventing moisture from affecting the insulation performance. The corrugated compensator automatically expands and contracts based on the required hot air purging temperature and the material of the hot air purging pipe, effectively coping with electrostatic precipitator operations under different environments.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a simple structure and convenient installation. It utilizes hot air generated during furnace smelting to purge and dry the interior of the 95mm ceramic conical sleeve, effectively preventing the accumulation of damp dust that could degrade its insulation performance. Simultaneously, a corrugated compensator regulates the hot air intake. This compensator automatically adjusts the pipe length and diameter based on the hot air temperature, ensuring a stable flow of hot air into the 95mm ceramic conical sleeve for purging and drying, thus reducing the blockage rate.

[0012] The present invention will be further described below with reference to the accompanying drawings. In the embodiments, unless otherwise specified, the technical means used are all conventional technical means in the art. Example 1

[0013] like Figure 1 The above-displayed top insulating support for an electrostatic precipitator is installed at the top of the cathode hanging rod 5 of the electrostatic precipitator and includes a 95-inch ceramic conical sleeve 1, a corrugated compensator 2, a sealing gland 3, and a hot air purging pipe 4. The 95mm conical ceramic sleeve 1 is fitted onto the top of the cathode hanging rod 5 of the electrostatic precipitator. A hot air inlet 6 is located on the side of the 95mm conical ceramic sleeve 1, connected to one end of a corrugated compensator 2. The other end of the corrugated compensator 2 is connected to a hot air purging pipe 4. One end of the hot air purging pipe 4 is connected to a main hot air pipe. The hot air inlet 6 is located 1cm below the middle of the 95mm conical ceramic sleeve 1. The 95mm conical ceramic sleeve 1 has a narrow top and wide bottom structure. The hot air inlet is located below the middle of the sleeve, maximizing the efficiency of purging the large space at the bottom of the 95mm conical ceramic sleeve 1, while the rising hot air can purge the small space at the top of the 95mm conical ceramic sleeve 1.

[0014] The sealing cap 3 is located on the top of the 95mm ceramic conical sleeve 1 and is fixed to the extended end of the cathode hanging rod 5 by a nut 7.

[0015] The working principle of this embodiment is as follows: A 95mm ceramic conical sleeve 1 is installed on the outer side of the top of the cathode hanging rod 5 of the electrostatic precipitator to ensure the insulation performance of the cathode hanging rod 5. Simultaneously, a sealing cap 3 is used at the top of the cathode hanging rod 5 to seal the portion of the cathode hanging rod 5 that penetrates the 95mm ceramic conical sleeve 1, preventing flue gas escape. A hot air inlet 6 is installed on the side of the 95mm ceramic conical sleeve 1, connected to a corrugated compensator 2, and then connected to a hot air purging pipe 4. This allows hot air from the main hot air pipe to be drawn into the 95mm ceramic conical sleeve 1 to purge accumulated dust and ash. The hot air also ensures the interior of the 95mm ceramic conical sleeve 1 remains dry, preventing moisture from affecting the insulation performance. The corrugated compensator 2 can automatically expand and contract based on the required hot air purging temperature and the material of the hot air purging pipe, effectively coping with electrostatic precipitator operations under different environments. The 95 ceramic conical sleeve has a narrow top and wide bottom structure. The hot air inlet is located in the middle of the sleeve, which can efficiently blow the large space at the bottom of the 95 ceramic conical sleeve. At the same time, the rising hot air can also blow the small space at the top of the 95 ceramic conical sleeve. Example 2
