Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to high-temperature flue gas pretreatment equipment for electrostatic precipitators. Background Art

[0002] Electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate dust from the flue gas emitted by coal-fired or oil-fired boilers, thereby significantly reducing the amount of dust discharged into the atmosphere. It is an important environmental protection equipment to improve environmental pollution and improve air quality.

[0003] Publication No. CN216800199U discloses an electrostatic precipitator device. The device is equipped with a nozzle, a connecting seat, a connecting pipe, a conveying pipe and an auger rod. When cleaning dust, the dust on the cathode plate is knocked to fall into the ash hopper. At this time, water is sprayed through the nozzle to reduce the escape of dust in the ash hopper. Then, the motor switch is turned on, and the motor drives the auger rod to rotate, so that the dust and water are mixed and the paste-like dust is conveyed to the discharge pipe for output. This reduces the tediousness of dust cleaning. At the same time, the dust is bound by water to prevent dust from escaping into the air. However, the following problems still exist in the actual use of this patent:

[0004] The device is provided with a nozzle, a connecting seat, a connecting pipe, a conveying pipe and an auger rod, which can achieve the goal of knocking the dust on the cathode plate into the ash hopper during dust cleaning. At this time, water is sprayed through the nozzle to reduce the escape of dust in the ash hopper, thereby preventing the dust from escaping into the air. In the prior art, the high-temperature flue gas emitted by coal-fired or oil-fired boilers usually needs to be pretreated before entering the electrostatic precipitator for treatment. This is because the direct entry of high-temperature flue gas into the electrostatic precipitator may cause a series of problems, affecting the dust removal effect and the stable operation of the electrostatic precipitator. However, the device does not have a high-temperature flue gas cooling structure, which may cause the high-temperature flue gas to damage the internal structure of the electrostatic precipitator, especially the electrodes and insulating materials.

[0005] An electrostatic precipitator high-temperature flue gas pretreatment device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a high-temperature flue gas pretreatment device for an electrostatic precipitator to solve the problem proposed in the above-mentioned background technology. At present, through the arrangement of the nozzle, connecting seat, connecting pipe, conveying pipe and auger rod, it can be achieved that when the dust is cleaned, the dust on the cathode plate is knocked to fall into the ash hopper.

In the prior art, the high-temperature flue gas emitted by coal-fired or oil-fired boilers usually needs to be pretreated before entering the electrostatic precipitator for treatment. This is because the high-temperature flue gas directly entering the electrostatic precipitator may bring a series of problems, affecting the dust removal effect and the stable operation of the electrostatic precipitator.

[0013] Preferably, a pull ring is installed on one end of the sliding rod away from the movable plate.

[0014] Preferably, the top of the brush plate fits into the filter screen.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the high-temperature flue gas pretreatment equipment of the electrostatic precipitator is as follows: the high-temperature flue gas flows inside the conveying pipe, the box body and the conical tube, and when the high-temperature flue gas is discharged in the form of bubbles through the aeration holes on the surface of the semicircular hole plate, the bubbles are in full contact with the cold water in the box body, thereby realizing heat exchange and achieving the effect of cooling the high-temperature gas. At this time, the particulate impurities in the gas are swept away by the cold water during the formation and rising of the bubbles. Therefore, this method helps to remove some of the particulate impurities in the gas, achieve a preliminary treatment effect on the high-temperature gas, and reduce the probability that the high-temperature flue gas may damage the internal structure of the electrostatic precipitator. By pulling the slide bar to slide inside the fixed tube, the slide bar drives the movable plate to slide inside the limit box. At this time, the second contraction spring contracts, and the reset property of the second contraction spring enables the plug-in block and the sealing plate to be connected, thereby achieving the effect of quickly installing and removing the sealing plate, and thus facilitating the staff to inspect and maintain the internal structure of the box.

[0016] 1. When the high-temperature flue gas flows inside the conveying pipe, box body and conical tube, and is discharged in the form of bubbles through the aeration holes on the surface of the semicircular orifice plate, the bubbles are fully in contact with the cold water in the box body, thereby realizing heat exchange and achieving the effect of cooling the high-temperature gas. At this time, the particulate impurities in the gas are swept away by the cold water during the formation and rising process of the bubbles. Therefore, this method helps to remove some of the particulate impurities in the gas, achieve the preliminary treatment effect of the high-temperature gas, and reduce the probability that the high-temperature flue gas may damage the internal structure of the electrostatic precipitator. The rotation of the driving rod drives the multiple sets of stirring blades to rotate. Using multiple sets of stirring blades to stir the cold water can significantly improve the mixing uniformity of the bubble gas and the cold water, and the turbulent effect generated by the stirring It helps to disperse the bubbles more evenly in the water, thereby increasing the contact area and contact time between the bubbles and the cold water, and improving the cooling effect. The staff starts the water pump to input the hot water into the condenser through the straw. At this time, the condenser uses heat exchange to cool the hot water. Finally, the cold water is discharged into the box through the valve pipe, so that the hot water can be quickly refrigerated and recycled, which greatly improves the cooling effect of high-temperature gas. Through the cooperation between the wheel and the belt, the rotating rod is driven to rotate inside the shell. The rotation of the first rotating tooth drives the rotation of the second rotating tooth. The rotation of the connecting rod drives the rotation of the brush plate. The rotation of the brush plate drives the bristles to clear the filter, thereby preventing the filter from being blocked by impurities and causing the water pump to run poorly.

[0017] 2. When the water pump is running, the suction pipe and the frame generate suction, causing the block to separate from the top inlet of the frame. At this time, the block drives the slide plate to move downward. At this time, the slide plate slides outside the fixed rod. At this time, the first contraction spring contracts. When the water pump is not running, the first contraction spring quickly resets, causing the block to fit with the top inlet of the frame, achieving an anti-backflow effect, thereby effectively preventing the backflow of cooling water. This can protect the water pump from the impact and damage of the backflow liquid and extend the service life of the water pump;

[0018] 3. The staff inserts the sealing plate into the top of the box body. At this time, the staff pulls the slide bar to slide inside the fixed tube. At this time, the slide bar drives the movable plate to slide inside the limit box. At this time, the second contraction spring contracts. At this time, the movable plate drives the roller to roll and connect inside the limit groove. By loosening the slide bar and then through the reset property of the second contraction spring, the plug-in block and the sealing plate can be plugged in, so that the sealing plate can be quickly installed and removed, which makes it easier for the staff to inspect and maintain the internal structure of the box body, and the roller is used to roll inside the limit groove, so that the movement of the movable plate can be more stable.

[0031] Working principle: Before using this electrostatic precipitator high temperature flue gas pretreatment equipment, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, the staff starts the high-temperature resistant fan to make the high-temperature flue gas flow inside the air inlet pipe 103. At this time, the high-temperature flue gas flows inside the delivery pipe 201, the box body 202 and the tapered tube 203. At this time, when the high-temperature flue gas is discharged in the form of bubbles through the aeration holes on the surface of the semicircular orifice plate 204, the bubbles are fully in contact with the cold water in the box body 101, thereby realizing heat exchange and achieving the effect of cooling the high-temperature gas. At this time, the particulate impurities in the gas are swept away by the cold water during the formation and rising process of the bubbles. Therefore, this method helps to remove some particulate impurities in the gas and realize preliminary treatment of the high-temperature gas. The effect is to reduce the probability that high-temperature flue gas may damage the internal structure of the electrostatic precipitator. At this time, the cooled gas is discharged into the interior of the electrostatic precipitator body 1 through the connecting pipe 102, and then the staff starts the motor 213 to drive the rotation of the driving rod 211. The rotation of the driving rod 211 drives the multiple sets of stirring blades 212 to rotate. The use of multiple sets of stirring blades 212 to stir the cold water can significantly improve the mixing uniformity of the bubble gas and the cold water. The turbulent effect generated by the stirring helps the bubbles to be more evenly dispersed in the water, thereby increasing the contact area and contact time between the bubbles and the cold water, and improving the cooling effect. When the box 1 When the cooling water inside 01 becomes hot, the staff starts the water pump 207 to input the hot water into the condenser 205 through the suction pipe 208. At this time, the condenser 205 uses heat exchange to cool the hot water. Finally, the cold water is discharged into the box body 101 through the valve pipe 206, so that the hot water can be quickly refrigerated and recycled, which greatly improves the cooling effect of the high-temperature gas. The rotation of the driving rod 211 drives the rotation of the wheel 216, and the cooperation between the wheel 216 and the belt 217 drives the rotating rod 215 to rotate inside the shell 209. The rotation of the rotating rod 215 drives the first rotating gear 218 rotates, the rotation of the first rotating tooth 218 drives the rotation of the second rotating tooth 219, the rotation of the second rotating tooth 219 drives the rotation of the connecting rod 2201, the rotation of the connecting rod 2201 drives the rotation of the brush plate 220, and the rotation of the brush plate 220 drives the bristles to clear the filter 210, thereby preventing the filter 210 from being clogged by impurities and causing the water pump 207 to operate poorly. In addition, the design of the filter 210 can prevent impurities from entering the water pump 207 or the condenser 205 and causing damage to the internal structure, which brings convenience to the staff during use;

[0032] When the water pump 207 is running, the suction pipe 208 and the frame 221 generate suction, so that the block 222 is separated from the top inlet of the frame 221. At this time, the block 222 drives the slide plate 223 to move downward. At this time, the slider 226 slides outside the fixing rod 225. At this time, the first contraction spring 227 contracts. When the water pump 207 is not running, the first contraction spring 227 quickly returns to its original position, so that the block 222 fits with the top inlet of the frame 221, achieving an anti-backflow effect, thereby effectively preventing the backflow of cooling water. This can protect the water pump 207 from the impact and damage of the backflow liquid and extend the service life of the water pump 207.

[0033] After that, the staff can insert the sealing plate 301 into the top of the box body 101, and at this time the staff pulls the slide bar 303 to slide inside the fixed tube 302, and at this time the slide bar 303 drives the movable plate 305 to slide inside the limit box 3011, and at this time the second contraction spring 304 contracts, and at this time the movable plate 305 drives the roller 308 to roll and connect inside the limit groove 307, and by loosening the slide bar 303, and then through the reset property of the second contraction spring 304, the plug-in block 306 can be plugged into the sealing plate 301, thereby achieving the effect of quickly installing and removing the sealing plate 301, which is convenient for the staff to inspect and maintain the internal structure of the box body 101, and using the roller 308 to roll inside the limit groove 307, the movable plate 305 can move more stably, and through the design of the pull ring 309, it is convenient for the staff to operate the slide bar 303.
