Description

Technical Field

[0001] This invention belongs to the technical field of protective equipment for electrostatic precipitators, and in particular relates to a protective device for an electromagnetic vibrator on the top of an electrostatic precipitator. Background Technology

[0002] Currently, electrostatic precipitators are usually installed in the open air on the top of generator sets. Electrostatic precipitators are essential supporting equipment for thermal power plants. Their function is to remove particulate matter from the flue gas emitted by stoves or oil-fired boilers, thereby significantly reducing the amount of dust emitted into the atmosphere. This is an important environmental protection device for improving environmental pollution and air quality.

[0003] The existing electromagnetic vibrators on the top of electrostatic precipitators vibrate continuously during operation. The cathode vibrator vibrates for a long time, which can accelerate the damage of the aging sealing ring and even cause the seal to fail. This leads to the intake of humid air into the insulation chamber along the seal gap, condensation on the vibrator rod cover, and water droplets flowing onto the surface of the vibrator insulation rod. Creepage breakdown can occur, causing a short circuit and tripping of the electric field, which affects the safe and stable operation of the electrostatic precipitator system and may even cause significant economic losses.

A return spring is movably sleeved on the wall of the T-shaped rod, and the two ends of the return spring are fixedly connected to the outer walls of the L-shaped plate and the T-shaped rod, respectively.

[0009] In the aforementioned protective device for the electromagnetic vibrator at the top of an electrostatic precipitator, the dehumidification mechanism includes an air hood fixedly connected to the top of an L-shaped plate. An inlet one-way valve and an outlet one-way valve are fixedly connected to the upper surface of the air hood. A flexible hose is fixedly connected to the output end of the outlet one-way valve, and a dehumidification box is fixedly connected to the output end of the flexible hose. A threaded hole is opened on the upper surface of the dehumidification box, and a sealing plug is threadedly connected to the wall of the threaded hole.

A guide rod is fixedly connected to the lower surface of the push plate. The bottom end of the guide rod passes through the upper surface of the L-shaped plate and is fixedly connected to a connecting mesh plate. Multiple vibration amplification springs are fixedly connected to the lower surface of the connecting mesh plate, and the bottom ends of the vibration amplification springs contact the upper surface of the outer cover.

[0010] In the above-mentioned protective device for the electromagnetic vibrator at the top of an electrostatic precipitator, the dehumidification component includes a sponge block fixedly connected to the inner wall of the mesh cylinder, a cloth bag fixedly connected to the outer wall of the sponge block, and the inside of the cloth bag is filled with a layer of dry silica gel particles.

[0011] In the protective device of the electromagnetic vibrator at the top of the electrostatic precipitator described above, the lower surface of the push plate and the upper surface of the L-shaped plate are connected together by two elastic ropes.

[0016] Compared with existing technologies, the advantages of a protective device for an electromagnetic vibrator on the top of an electrostatic precipitator are:

[0017] 1. Through the installation of protective mechanisms, waterproof covers, and fixing mechanisms, when the electromagnetic vibrator on the top of the electrostatic precipitator is working, a waterproof cover is first installed on the outside of the electromagnetic vibrator to provide reliable sealing protection. Then, the protective mechanism further seals and protects the electromagnetic vibrator on the top of the electrostatic precipitator. Moreover, the fixing mechanism allows for easy disassembly of the outer cover and the corrugated rubber sleeve in the protective mechanism, thus not affecting the normal operation and daily maintenance of the original cathode vibrator. This mechanism can effectively improve the sealing and protection effect of the electromagnetic vibrator on the top of the electrostatic precipitator, preventing moisture from entering the interior of the electromagnetic vibrator and causing short circuits and tripping of the electric field. This not only ensures the safe and stable operation of the electrostatic precipitator system but also avoids unnecessary economic losses.

[0018] 2. Through the dehumidification mechanism and dehumidification components, when the electromagnetic vibrator at the top of the electrostatic precipitator vibrates, the vibration is transmitted through the outer cover to the vibration amplification spring. The vibration amplification spring, through the connecting mesh plate and guide rod, causes the push plate to move back and forth. During the reciprocating movement of the push plate, the dehumidification mechanism transports the air near the electromagnetic vibrator at the top of the electrostatic precipitator to the dehumidification components in the dehumidification box for dehumidification. Finally, the dry air is discharged. This mechanism enables the protective device of the electromagnetic vibrator at the top of the electrostatic precipitator to have the function of air drying, improves the protective effect of the device, and ensures the safe and stable operation of the electrostatic precipitator system.

[0028] Example 2 is based on Example 1, such as... Figure 1 and Figure 4As shown, a dehumidification mechanism 8 is fixedly connected to the upper surface of the L-shaped plate 14. The dehumidification mechanism 8 includes an air hood 81 fixedly connected to the top of the L-shaped plate 14. An inlet one-way valve 82 and an outlet one-way valve 83 are fixedly connected to the upper surface of the air hood 81. A hose 84 is fixedly connected to the output end of the outlet one-way valve 83. A dehumidification box 85 is fixedly connected to the output end of the hose 84. A threaded hole is opened on the upper surface of the dehumidification box 85, and a sealing plug 86 is threadedly connected to the wall of the threaded hole. A mesh cylinder 87 is fixedly connected to the bottom end of the sealing plug 86. An L-shaped air pipe 88 is fixedly connected to the upper surface of the sealing plug 86. A push plate 89 is movably connected to the inner wall of the air hood 81. The lower surface of the push plate 89 and the upper surface of the L-shaped plate 14 are connected to two elastic ropes 15. The elastic ropes 15 enable the push plate 89 to move up and down reciprocally. The lower surface of the push plate 89 is fixedly connected to a guide rod 810. The bottom end of the guide rod 810 passes through the upper surface of the L-shaped plate 14 and is fixedly connected to a connecting mesh plate 811. The lower surface of the connecting mesh plate 811 is fixedly connected to multiple vibration amplification springs 812. The bottom end of the vibration amplification springs 812 contacts the upper surface of the outer cover 2. This mechanism enables the protective device of the electromagnetic vibrator at the top of the electrostatic precipitator to have an air drying function, improves the protective effect of the device, and ensures the safe and stable operation of the electrostatic precipitator system.

[0029] The inner wall of the mesh cylinder 87 is connected to a dehumidification component 9, which includes a sponge block 91 fixedly connected to the inner wall of the mesh cylinder 87. A cloth bag 92 is fixedly connected to the outer wall of the sponge block 91. The inside of the cloth bag 92 is filled with a layer of dry silica gel particles 93. This mechanism can ensure the effect of air drying.

[0030] The operating principle of this invention is described as follows: When the electromagnetic vibrator at the top of the electrostatic precipitator is working, a waterproof cover 13 is first installed on the outside of the electromagnetic vibrator, and the bottom of the waterproof cover 13 is sealed to provide reliable sealing protection. Furthermore, a sponge sound insulation layer 20 is installed inside the waterproof cover 13 to reduce noise. Next, the protective mechanism 6 further seals and protects the electromagnetic vibrator at the top of the electrostatic precipitator. The corrugated rubber sleeve 62, with the cooperation of the third connecting ring 61, provides a secondary seal. The fixing mechanism 7 facilitates the removal of the outer cover 2 and the corrugated rubber sleeve 62 in the protective mechanism 6, thus not affecting the normal operation and daily maintenance of the original cathode vibrator. When the electromagnetic vibrator at the top of the electrostatic precipitator vibrates, the vibration is transmitted through the outer cover 2 to the vibration amplification spring 812, and the vibration amplification spring 812... Connecting the mesh plate 811 and the guide rod 810 causes the push plate 89 to reciprocate. During the reciprocating movement of the push plate 89, in conjunction with the air hood 81, the inlet one-way valve 82, and the outlet one-way valve 83, the air near the electromagnetic vibrator at the top of the electrostatic precipitator is transported to the dehumidification component 9 in the dehumidification box 85 for dehumidification. The sponge block 91 and the dry silica gel particle layer 93 can absorb the moisture in the air. Finally, the dried air is discharged, which can further reduce the humidity of the air near the electromagnetic vibrator at the top of the electrostatic precipitator. This mechanism can effectively improve the sealing and protection effect of the electromagnetic vibrator at the top of the electrostatic precipitator. Moreover, the protective device of the electromagnetic vibrator at the top of the electrostatic precipitator also has the function of air drying, preventing moisture from entering the interior of the electromagnetic vibrator at the top of the electrostatic precipitator and causing short circuit tripping of the electric field. This not only ensures the safe and stable operation of the electrostatic precipitator system, but also avoids unnecessary economic losses.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
