Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for electrical equipment, specifically an electrical dust collector for thermal power plants. Background Technology

[0002] A thermal power plant is a place that uses heat energy to generate electricity. A thermal power plant refers to a thermal power plant that uses steam extracted or exhausted from a steam turbine to supply heat to users while generating electricity. It must be located near the heat load center, which is often the town center of a densely populated area. Its water use, land acquisition, demolition, and environmental protection requirements are much higher than those of thermal power plants of the same capacity. At the same time, a heat pipeline network is also built. Thermal power plants also contain electrical equipment such as transformers and high-voltage switchgear. These devices are installed in the power distribution room. During long-term operation, a lot of dust will accumulate on the surface of the equipment or on the dust screen.

[0003] To prevent dust from affecting the heat dissipation of electrical equipment, regular dust removal is necessary. Traditional methods rely on manual dust removal, which is inefficient and prone to causing significant dust dispersion. Therefore, we propose an electrostatic precipitator for thermal power plants. Utility Model Content

[0004] The purpose of this utility model is to provide an electrostatic precipitator for thermal power plants. By combining a blower for blowing dust and a collection box for collecting dust, the dust of electrical equipment can be removed by blowing air with an air pump, and the blown-down dust can be quickly collected into the collection box. This method can efficiently remove dust by blowing air and at the same time avoid the spread of dust during the dust removal process, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrostatic precipitator for thermal power plants, comprising a collection box, a movable plate, and a blower duct. An upper plate parallel to the movable plate is fixed above it. An air pump is installed between the upper plate and the movable plate. The outlet of the air pump is connected to the blower duct via a flexible hose. Multiple air outlet pipes communicating with the interior of the blower duct are evenly connected to its side. A top cover is placed on top of the collection box, with a side opening communicating with its interior on its surface. A bottom plate is horizontally fixed below the interior of the collection box. A downward-blowing fan is installed between the bottom plate and the bottom of the collection box. Through-holes are opened on the surface of the bottom plate above the fan and the surface of the collection box below the fan. A mesh cylinder is also supported inside the collection box above the bottom plate, with through holes evenly distributed on its surface.

[0006] By adopting the above technical solution, the air pump is used to blow air through the air outlet pipe to remove dust from the surface of electrical equipment. The blown-off dust can be sucked into the collection box and collected in the cloth bag inside the mesh cylinder, thus achieving the purpose of efficient dust removal and preventing dust spread.

[0007] Optionally, a handle is fixed to the side of the hair dryer by two connecting rods, and the handle is parallel to the hair dryer.

[0009] Optionally, a vertical pole is fixed at the upper center of the upper plate, and the handle on the side of the blower is sleeved on the upper outer ring of the pole, with the bottom of the handle supported on the support plate fixed on the upper outer ring of the pole.

[0010] By adopting the above technical solution, the blower can be easily hung and fixed when not in use by using the upright, support plate and handle.

[0011] Optionally, each of the four bottom corners of the collection box is equipped with a first omnidirectional wheel, and there are four first omnidirectional wheels.

[0012] By adopting the above technical solution, the collection box can be easily moved using the first omnidirectional wheel.

[0013] Optionally, four second omnidirectional wheels are installed at the four bottom corners of the movable plate.

[0014] By adopting the above technical solution, the movable plate and its upper structure can be easily moved using the second omnidirectional wheel.

[0015] Optionally, the bottom outer ring of the top cover is provided with an insert plate, which is inserted into a slot opened on the inner side of the collection box.

[0016] By adopting the above technical solution, the insert plate is inserted into the slot, so that the top cover is stably placed above the collection box.

[0017] Optionally, the top cover has side openings on all four sides and the top surface, and multiple side openings are provided.

[0018] By adopting the above technical solution, the dust blown down for cleaning can more easily enter the collection box from the side opening with the airflow.

[0019] Optionally, the top height of the mesh cylinder is less than the bottom height of the top cover.

[0020] By adopting the above technical solution, it is ensured that dust entering from the side opening of the top cover can fall smoothly into the cloth bag inside the mesh cylinder for collection.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

Detailed Implementation

[0030] Please see Figure 1-4This utility model provides a technical solution: an electrostatic precipitator for thermal power plants, including a collection box 1, a movable plate 3, and a blower 4. In order to achieve efficient dust removal, an upper plate 31 parallel to the movable plate 3 is fixed above it. An air pump 34 is installed between the upper plate 31 and the movable plate 3. The air pump 34 is used to compress air, and the outlet of the air pump 34 is connected to the blower 4 through a hose 43. Multiple air outlet pipes 41 connected to the inside of the blower 4 are evenly connected to the side of the blower 4. When removing dust, the air pump 34 is connected to the power supply and is started. Compressed air is supplied to the blower 4 through the hose 43, so that the high-speed airflow is discharged from the air outlet pipes 41 on the side of the blower 4, which can blow away the dust adhering to the surface of electrical equipment or dustproof net.

[0031] Since the blown dust floats in the air and needs to be collected quickly, a top cover 2 is placed on top of the collection box 1. An insert plate 22 is arranged around the bottom outer ring of the top cover 2. The insert plate 22 is inserted into the slot 12 opened on the inner side of the top of the collection box 1, so that the top cover 2 can be detached and fixed, making it convenient to open the collection box 1 when needed. The surface of the top cover 2 has a side opening 21 that communicates with its interior, and the top and sides of the top cover 2 also have side openings 21. There are multiple side openings 21.

[0032] To achieve the purpose of sucking in and collecting dust, a base plate 13 is horizontally fixed at the bottom of the inside of the collection box 1. A fan 14 that blows downwards is installed between the base plate 13 and the bottom of the collection box 1. Both the base plate 13 above the fan 14 and the surface of the collection box 1 below the fan 14 have through openings 15. The inside of the collection box 1 above the base plate 13 is also supported by a mesh cylinder 16. The surface of the mesh cylinder 16 is evenly provided with through holes. When in use, a breathable cloth bag needs to be put inside the mesh cylinder 16 first, and then the top cover 2 is closed. The fan 14 is then turned on and blows downwards. The external airflow will carry the dust blown out and enter the top cover 2 and the inside of the collection box 1 through the side opening 21, and continue to flow downwards, so that the dust is collected and left inside the cloth bag. In addition, in order to ensure that the dust entering from any side opening 21 can be collected into the cloth bag, the top height of the mesh cylinder 16 is made smaller than the bottom height of the top cover 2.

[0033] A handle 42 is fixed to the side of the hair dryer 4 by two connecting rods. The handle 42 is parallel to the hair dryer 4, and the two connecting rods are also parallel to each other. When in use, the handle 42 serves as a handle for convenient operation of the hair dryer 4. A vertical pole 32 is also fixed in the middle of the upper plate 31. When not in use, the handle 42 on the side of the hair dryer 4 can be fitted onto the upper outer ring of the vertical pole 32, and the bottom of the handle 42 is supported on the support plate 321 fixed on the upper outer ring of the vertical pole 32, which allows the hair dryer 4 to be hung.

[0034] In addition to the above structure, the bottom four corners of the collection box 1 are equipped with first universal wheels 11, and the bottom four corners of the moving plate 3 are equipped with second universal wheels 33. There are four of each type of universal wheel 11 and universal wheel 33, which can facilitate the movement of the collection box 1 and the moving plate 3. In addition, the first universal wheels 11 and universal wheels 33 are universal wheels with a brake structure, which can be locked when needed.

[0035] In use, guided by the first caster wheel 11, the collection box 1 is moved to the side of the electrical equipment requiring dust removal, and the brakes on the first caster wheel 11 are locked. Guided by the second caster wheel 33, the moving plate 3 is also moved to the side of the electrical equipment requiring dust removal, and the brakes on the second caster wheel 33 are locked as well. The control terminals of the fan 14 and the air pump 34 are connected to the industrial control panel and powered on. After removing the top cover 2 of the collection box 1, a breathable collection bag is placed inside the mesh cylinder 16, and the top cover 2 is replaced again. It is necessary to ensure that the top of the bag is fitted over the outer ring of the mesh cylinder 16. The fan 14 and the air pump 34 are then started. Then, lift the handle 42 to remove the blower 4. Use the handle 42 as a handle to operate the blower 4, causing the air pump 34 to blow air into the blower 4 through the hose 43 and out through the air outlet 41. Align the air outlet 41 with the dusty area on the surface of the electrical equipment to blow away the dust. Due to the downward blowing action of the fan 14, external air enters the collection box 1 through the side opening 21, and the airflow carries the blown-down dust into the collection box 1 through the side opening 21, eventually collecting it in the cloth bag in the mesh cylinder 16. Afterwards, when stopping the machine, the top cover 2 can be removed and the cloth bag can be taken out. After use, stop the fan 14 and the air pump 34, and the handle 42 can be put back on the outer ring of the upright 32 and supported on the support plate 321.
