Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic precipitator equipment, and in particular to a fiberglass electrostatic precipitator insulator chamber structure. Background Technology

[0002] Electrostatic precipitators (ESPs) are key equipment in the environmental protection field used to purify gases containing droplets, dust, and harmful gases. They are widely used in industries such as sulfuric acid production, metallurgy, and chemicals. Their core function is to charge pollutants in the gas through a high-voltage electric field, thereby collecting and removing them to achieve compliant emissions. The insulator chamber, as an important component of the ESP, plays a crucial role in supporting the cathode frame, isolating the high-voltage electric field from the external environment, and ensuring stable transmission of high-voltage electricity. Its performance directly determines the operational reliability and purification efficiency of the ESP.

[0003] However, traditional electrostatic precipitator insulator chambers have several shortcomings in practical applications: First, the sealing structure design is unreasonable, often employing a single sealing method, which is prone to seal failure due to assembly errors or long-term operation. This allows external moisture and dust to enter the insulator chamber, adhere to the surface of the insulating components, and cause creepage and discharge faults, which can even lead to high-voltage circuit interruption in severe cases. Second, there is a lack of effective temperature control mechanisms. In low-temperature or high-humidity environments, condensation easily forms on the inner wall of the insulator chamber, damaging insulation performance and further increasing the risk of failure. Third, the protection of high-voltage conductive components is insufficient, often directly exposed or simply wrapped, making them susceptible to external impacts and corrosion, leading to unstable high-voltage transmission. Furthermore, the lack of a buffer structure means that assembly errors can easily cause stress damage to conductive components. Fourth, the overall structural support stability is poor. Some use non-metallic shells, which are insufficient in strength and prone to deformation after long-term use, affecting the positioning accuracy and working condition of the internal units.

[0004] The aforementioned defects lead to frequent shutdowns for maintenance of traditional insulator chambers, which not only reduces the operating efficiency of the electrostatic precipitator but also increases equipment maintenance costs and spare parts replacement expenses. This makes it difficult to meet the long-term stable operation requirements of electrostatic precipitators in industrial production. Therefore, there is an urgent need for an insulator chamber structure that is reliably sealed, temperature-controllable, has stable high-voltage transmission, and a robust structure to solve the problems existing in the current technology.

[0008] Preferably, the insulator chamber shell is a circular stainless steel shell with a diameter of 1600-2000 mm and a height of 1500 mm.

[0009] Preferably, the high-voltage conductive unit includes a high-voltage protective cover, a through-ceramic insulator, and a high-voltage connecting wire; The high-voltage protection cover is located outside the high-voltage generator and is connected to the outer shell of the insulator chamber to protect the high-voltage generator and the line; one end of the through porcelain insulator is connected to the damping resistor of the high-voltage generator, and the other end is screwed to the support rod; One end of the high-voltage connecting wire is connected to the through porcelain insulator, and the other end is connected to the support rod, realizing a flexible connection between the through porcelain insulator and the support rod.

[0011] Preferably, the control unit includes a temperature detection device and a control device; The temperature detection device is located on the side of the insulator chamber shell, with one end extending into the interior of the insulator chamber, and is used to detect temperature changes inside the insulator chamber.

[0013] Preferably, the sealing gasket is made of a material with high insulation properties, specifically PTFE or asbestos.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model, through the optimized design of the quartz basin unit, adopts a conical quartz basin body that is thinner at the top and thicker at the bottom, and is equipped with a PTFE sealing gasket, a high-insulation sealing gasket, and a double sealing structure of the upper end cover and the bottom connecting flange.

[0022] This application provides a fiberglass electrostatic precipitator insulator chamber structure, which effectively solves the technical problems of traditional electrostatic precipitator insulator chambers, such as poor sealing performance, difficulty in temperature control, unstable high-voltage transmission, easy creepage discharge faults, and poor structural support, which lead to frequent equipment shutdowns for maintenance, low operating efficiency, and high maintenance costs. Example

[0023] like Figure 1-2 As shown, the overall technical solution in this application embodiment is as follows: To address the problems existing in the prior art, this utility model provides a fiberglass electrostatic precipitator insulator chamber structure, specifically including a quartz basin unit 1, a high-voltage conductive unit 2, a micro-heating unit 3, an insulator chamber shell 4, and a control unit 5. Each unit works together through a pre-set assembly relationship to achieve the functions of sealing and isolation, high-voltage conduction, temperature control, and structural support of the insulator chamber. The assembly details of each unit and the overall working process are described in detail below: The insulator chamber outer shell 4 is a circular stainless steel shell with a diameter of 1600-2000mm and a height of 1500mm. It is distributed on the outside of the insulator chamber and serves as the core support frame of the entire structure. During assembly, the insulator chamber outer shell 4 is first aligned and fixed with the main structure of the electrostatic precipitator using pre-set fixing brackets to ensure that the shell is vertical and tilt-free. This provides a flat and stable foundation for the subsequent installation of internal units and also protects against external impurities, rainwater, and impacts.

[0024] Quartz basin unit 1 is installed inside the insulator chamber shell 4 and is the core component for achieving isolation and sealing between the electric field and the insulator chamber. Its assembly process and the function of each sub-component are as follows: Positioning of the quartz basin body 11: The quartz basin body 11 is a cone-shaped body that is thinner at the top and thicker at the bottom. It is made of quartz and its height is controlled between 500-700mm. The inner diameter of the upper part is 360mm and the outer diameter is 520mm. The inner diameter of the lower part is 480mm and the outer diameter is 590mm. During assembly, the quartz basin body 11 is placed vertically in the center of the insulator chamber shell 4, ensuring that its axis coincides with the axis of the insulator chamber shell 4.

[0025] Assembly of the upper end cap 12 and sealing structure: The upper end cap 12 is made of stainless steel and covers the upper surface of the quartz basin body 11; a sealing gasket 13 is laid between the upper end cap 12 and the quartz basin body 11. The sealing gasket 13 is made of PTFE. The upper end cap 12 and the quartz basin body 11 are fastened by the cover plate clamping bolts 19. The cover plate clamping bolts 19 are made of ordinary carbon steel or stainless steel. When tightening, a diagonal and uniform force is applied to ensure that the sealing gasket 13 is fully compressed to achieve upper sealing.

[0026] Assembly of support rod 14 and insulation structure: PTFE bushing 15 is embedded in the middle of upper end cover 12, with a central opening of ¢38mm for the support rod 14 to pass through; one end of support rod 14 extends out of upper end cover 12, and the other end passes through PTFE bushing 15 and extends into the quartz basin body 11 and remains centered; a metal adjusting shim 16 is fitted on the outside of the end of support rod 14 that extends out of upper end cover 12, a fixing nut 17 is screwed on the metal adjusting shim 16, and a locking nut 18 is screwed on the fixing nut 17. The position of support rod 14 is adjusted by tightening the fixing nut 17, and the locking nut 18 is tightened to prevent loosening. The metal adjusting shim 16, fixing nut 17, and locking nut 18 are all made of ordinary carbon steel or stainless steel.

[0027] Bottom connection and sealing assembly: Base connecting flange 111 is fitted around the quartz basin body 11 and located at its bottom, and is made of stainless steel; base connecting flange 112 is fitted on the upper part of the connection end of the electrostatic precipitator body support tube, and is made of stainless steel; a sealing gasket 113 is laid between base connecting flange 111 and base connecting flange 112, and the sealing gasket 113 is made of PTFE or asbestos (with high insulation performance). The two are then screwed together and fixed by base fastening bolts 110, which are made of stainless steel, to ensure the sealed connection and insulation isolation between the quartz basin unit 1 and the electrostatic precipitator body.

[0028] The high-voltage conductive unit 2 is installed on the side of the insulator chamber shell 4 and is used to transmit high-voltage electricity to the electric field cathode. Its assembly process is as follows: The high-voltage protection cover 21 is installed on the outside of the high-voltage generator. The edge of the high-voltage protection cover 21 is welded or bolted to the side of the insulator chamber shell 4 to form physical protection for the high-voltage generator and subsequent lines, avoiding the impact of external collisions or pollutants.

[0029] One end of the through-insulator 22 is fixedly connected to the damping resistor of the high-voltage generator by bolts, and the other end extends into the interior of the insulator chamber shell 4 and is screwed to the support rod 14. The through-insulator 22 plays a dual role as a high-voltage insulation and conductive carrier.

[0030] One end of the high-voltage connecting wire 23 is crimped or bolted to the end of the through porcelain insulator 22 away from the high-voltage generator, and the other end is crimped or bolted to the corresponding position of the support rod 14, forming a flexible connection between the through porcelain insulator 22 and the support rod 14, which ensures the stable transmission of high-voltage electricity and can adapt to assembly errors or a small amount of structural displacement.

[0031] The micro-heating unit 3 is installed on the side of the insulator chamber shell 4 to maintain the temperature inside the insulator chamber. Its assembly process is as follows: The heaters 32 are electrically heated and are evenly arranged along the circumference of the circular body of the insulator chamber shell 4. Three sets of heaters 32 are installed on each insulator chamber shell 4, and the three sets of heaters 32 are distributed at a 120° angle to ensure the uniformity of heating inside the insulator chamber.

[0032] A heater protective cover 31 is installed on the outside of each heater 32. The bottom of the heater protective cover 31 is welded and fixed to the side of the insulator chamber shell 4. A rectangular or circular opening is opened on the upper part of the heater protective cover 31. The opening size is slightly larger than the shape of the heater 32 to facilitate the disassembly and maintenance of the heater 32. A rain cover (made of stainless steel) is welded on the top of the heater protective cover 31 to prevent rainwater from entering and damaging the heater 32.

[0033] Control unit 5 is used to automatically control the temperature inside the insulator chamber. Its assembly and control logic is as follows: The temperature detection device 51 uses a temperature sensor (such as a platinum resistance sensor). Its probe extends into the insulator chamber through a pre-set opening on the side of the insulator chamber shell 4. The sensor body is fixed to the insulator chamber shell 4 by a flange or thread to ensure that the probe can detect the temperature change inside the insulator chamber in real time.

[0034] The control device 52 (such as a PLC controller or temperature controller) is installed in the power distribution room and is connected to the temperature detection device 51 and the heater 32 via cables. The control device 52 has a preset temperature control threshold (usually set above 100°C to ensure water vapor evaporation). When the temperature detection device 51 detects that the temperature in the insulator room is lower than the threshold, the control device 52 sends a signal to start the heater 32. When the temperature is higher than the threshold, the control device 52 sends a signal to stop the heater 32, so as to realize the intermittent operation of the heater 32 and achieve energy saving.

[0035] Overall work process: Isolation and protection: The quartz basin unit 1 effectively isolates the electric field from the inside of the insulator chamber through the insulating and sealing effect of the upper sealing gasket 13, the bottom sealing gasket 2 113 and the PTFE bushing 15, preventing smoke particles and water vapor in the electric field from entering the insulator chamber and eliminating the occurrence of creepage faults from the root.

[0036] High-voltage transmission: The high-voltage electricity generated by the high-voltage generator is transmitted to the support rod 14 through the porcelain insulator 22 and the high-voltage connecting wire 23, and then to the electric field cathode through the support rod 14, so as to realize the stable transmission of high-voltage electricity and ensure the normal operation of the electric field of the electrostatic precipitator.

[0037] Temperature control: The temperature detection device 51 collects the temperature inside the insulator chamber in real time and transmits it to the control device 52. The control device 52 controls the start and stop of the heater 32 according to the preset threshold, so that the temperature inside the insulator chamber is always kept above 100℃, preventing water vapor from adhering to the inner wall of the quartz basin body 11, and further reducing the probability of discharge faults. At the same time, the intermittent operation of the heater 32 greatly reduces power consumption, which meets the requirements of energy conservation and carbon reduction.

[0038] This embodiment effectively solves the problems of traditional insulator chambers being prone to moisture discharge, high energy consumption, and high maintenance risks by precisely assembling and coordinating the work of each unit, ensuring the stable operation of the FRP electrostatic precipitator and improving the safety and efficiency of subsequent sulfuric acid production processes.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
