Description

Technical Field

[0001] This invention relates to the field of electrostatic precipitators, and more specifically to an electrostatic precipitator equipped with a multifunctional corona electrode anti-sway structure. Background Technology

[0002] In electrostatic precipitator technology, the canopy structure of traditional electrostatic precipitators cannot evenly distribute the impact force of flue gas, resulting in excessive local stress on the canopy and causing it to shake. This shaking not only reduces the operating efficiency of the equipment, but may also damage the canopy and related components, shortening the service life of the equipment.

[0003] When electrode posts malfunction and require maintenance, the lack of effective disassembly devices often necessitates extensive disassembly by operators. This not only consumes significant time and manpower, increasing maintenance costs, but also risks secondary damage due to improper operation during disassembly and installation, affecting the normal operation of the equipment. However, a new technology addresses this issue by using a hydraulic push rod to move the ceramic support upwards. The ceramic support, through a rubber pad, presses upwards against the ceramic positioning seat, lifting the lower suspension and causing the bottom hook of the electrode post to separate from the second fixing ring. This allows for rapid disassembly of the electrode post for maintenance.

[0004] To address the aforementioned issues, we propose an electrostatic tar precipitator equipped with a multifunctional corona electrode anti-sway structure. Summary of the Invention

[0005] The purpose of this invention is to provide an electrostatic tar precipitator equipped with a multifunctional corona electrode anti-sway structure to address the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrostatic precipitator for tar removal equipped with a multifunctional corona electrode anti-sway structure, comprising an electrostatic precipitator tank, a support ring fixedly provided on the inner wall of the electrostatic precipitator tank, a sedimentation tube installed inside the electrostatic precipitator tank through the support ring, and a suspension mechanism inside the electrostatic precipitator tank, wherein a ceramic positioning seat is fixedly provided at the bottom center of the suspension mechanism, a rubber pad is fixedly provided at one bottom end of the ceramic positioning seat, and a vertically upward hydraulic push rod is fixedly provided at the bottom center of the electrostatic precipitator tank, wherein a ceramic support is fixedly provided at the output end of the hydraulic push rod, and the ceramic support is located directly below the rubber pad; The suspension mechanism includes an upper suspension and a lower suspension. The upper suspension is located at the top of the sedimentation tube, and the lower suspension is located at the bottom of the sedimentation tube. The bottom outer wall of the upper suspension has equidistantly distributed sliding tubes. The inner wall of each sliding tube is slidably connected to equidistantly distributed ball bearings. The bottom outer wall of each ball bearing is fixed with a vertically downward lifting rod. One bottom end of the lifting rod is fixed with a first fixing ring. The top outer wall of the lower suspension has equidistantly distributed second fixing rings fixed via a bracket. An electrode post is located between the first and second fixing rings, penetrating the interior of the sedimentation tube. Hooks are fixed at the top and bottom ends of the electrode post, hooking onto the inner walls of the first and second fixing rings. The upper and lower suspensions form a regular hexagonal spiderweb structure. The bottom six ends of the lower suspension are connected to counterweight cones via ropes.

[0007] Preferably, the ceramic positioning seat is installed at the bottom center of the lower parachute.

[0008] Preferably, an insulating sleeve is fixedly installed at the top center of the electrostatic precipitator tank through an opening. An insulator is fixedly installed inside the insulating sleeve. A vertically downward connecting rod is installed on the insulator. One bottom end of the connecting rod is fixedly connected to the top center of the upper canopy. Sub-supports are welded to the six outer walls of the upper canopy. The other end of the sub-supports is fixedly connected to the outer wall of the connecting rod by welding.

[0009] Preferably, an air inlet pipe is fixedly provided on one side of the bottom of the electrostatic precipitator tank through an opening, and an exhaust pipe is fixedly provided on one side of the top of the electrostatic precipitator tank through an opening.

[0010] Preferably, the bottom outer wall of the electrostatic tar collector tank is connected to a downwardly inclined drain pipe through an opening.

[0011] Preferably, a manhole is fixedly provided on one side of the outer wall of the electrostatic precipitator tank through an opening, the manhole including a sealing cover and a door handle installed on the sealing cover.

[0012] Preferably, the bottom outer wall of the electrostatic precipitator tank is provided with vertically downward supporting legs that are evenly distributed and fixed by welding.

[0013] S1: The flue gas enters from the bottom of the side of the electrostatic precipitator tank and passes through the upper and lower suspended umbrellas in a regular hexagonal spider web structure. This structure makes the overall force uniform and can effectively disperse the force brought by the flue gas impact. S2: The counterweight cone block connected by ropes to the six ends of the lower canopy further increases the stability of the canopy structure and reduces the swaying of the canopy caused by factors such as flue gas flow. The electrode column penetrates the inside of the sedimentation tube. Under the action of the electric field, tar droplets and other impurities are charged and move towards the electrode column under the action of the electric field force, and finally attach to the electrode column to achieve the purification of flue gas. The purified gas is discharged from the exhaust pipe at the top of one side of the electrostatic precipitator tank. S3: When the electrode column needs maintenance or replacement, first use the hydraulic push rod to move the ceramic support upward, so that the ceramic support contacts the rubber pad and lifts the lower umbrella to a certain height. At this time, the hook at the top of the electrode column is still engaged with the first fixing ring at the bottom of the upper umbrella, and the hook at the bottom of the electrode column is separated from the second fixing ring at the top of the lower umbrella. The operator can open the sealing cover through the manhole to enter the tank and easily remove the electrode column from the first fixing ring for maintenance or replacement. After maintenance or replacement is completed, use the hydraulic push rod to lower the ceramic support, allowing the lower umbrella to return to its original position, and re-engage the hook at the bottom of the electrode column with the second fixing ring to allow the equipment to operate normally.

[0014] The technical effects and advantages provided by the present invention in the above technical solution are as follows: The upper and lower canopies employ a hexagonal spiderweb structure, which evenly disperses the impact force of the flue gas and effectively prevents the canopies from swaying due to excessive local stress. In addition, the counterweight cones at the bottom of the lower canopy, connected by ropes to the six ends of the outer wall, greatly improve the stability of the canopy during operation and provide a stable operating environment for the electrode column.

[0015] The ceramic support is pushed upward by the hydraulic push rod. The ceramic support then presses the ceramic positioning seat upward through the rubber pad, which lifts the lower suspension umbrella and separates the bottom hook of the electrode column from the second fixing ring. This allows the electrode column to be quickly removed from the equipment, facilitating its maintenance. Attached Figure Description

[0024] Working principle of this invention: Refer to the instruction manual appendix Figure 1-7First, the generated flue gas is connected to the inlet pipe 22 through a pipe. The flue gas enters from the inlet pipe 22 at the bottom of one side of the electrostatic precipitator tank 1. It passes through the upper canopy 4 and the lower canopy 5 in a regular hexagonal spider web structure. This structure makes the overall force uniform and can effectively disperse the force brought by the flue gas impact, reducing shaking.
