Description

Technical Field

[0001] This utility model relates to electrostatic adsorption dust removal equipment, specifically to a self-cleaning electrostatic adsorption dust removal equipment capable of automatically cleaning dust and other impurities. Background Technology

[0002] Electrostatic adsorption dust removal equipment includes a discharge element and an adsorption element. The discharge element is connected to the negative terminal of the power supply, and the adsorption element is grounded or connected to the positive terminal of the power supply. When the discharge element is energized, a voltage difference is formed between the discharge element and the adsorption element. Dust exists in the gap between the discharge element and the adsorption element, and some of the dust...

[0003] The discharge element is connected to the negative terminal of a power source, and the adsorption element is grounded or connected to the positive terminal of the power source. A gap is left between the discharge element and the adsorption element. The dust-laden gas to be treated passes through the gap between the discharge element and the adsorption element. Some dust particles combine with electrons, become negatively charged, and tend to discharge and deposit on the surface of the adsorption element. However, the exhaust gas contains various impurities such as dust and oil. These impurities are difficult to clean after depositing on the adsorption element, and the deposited impurities will affect the performance and service life of the dust removal equipment.

[0008] Preferably, the adsorption element is a hollow tube, and the discharge element is a discharge rod disposed inside the hollow tube.

[0009] Preferably, the water supply system includes an outer plate outside the adsorbent, the outer plate and the outer wall of the adsorbent forming a water storage cavity, the water storage cavity is connected to a water supply device for supplying water to the water storage cavity, the upper part of the adsorbent is provided with a water outlet hole, the water in the water storage cavity seeps into the adsorption surface of the adsorbent from the water outlet hole, and forms a downward flowing water film on the adsorption surface.

[0010] Preferably, a flexible cloth is provided at the height of the water outlet, and the flexible cloth is fixed to the inner or outer wall of the adsorption element.

[0011] Preferably, the water supply system includes a water storage tank, which is connected to the lower part of the water storage chamber.

[0015] Compared with the prior art, the self-cleaning electrostatic adsorption dust removal equipment provided by this utility model has the following advantages:

[0016] Conventional electrostatic adsorption dust removal equipment requires manual or mechanical cleaning of the adsorption components when impurities accumulate on them. When the deposits contain oil, the impurities adhere to the components, making cleaning difficult and potentially damaging. However, in this invention, the adsorption components are connected to a water supply system, which creates a water film on the components. This water film acts as a positive electrode, adsorbing dust and other impurities directly onto it. As the water film flows downwards, it carries the adsorbed dust and impurities away from the components, preventing excessive accumulation. This design enables the adsorption components to automatically clean themselves of adsorbed dust and impurities, preventing buildup and eliminating the need for manual cleaning. This significantly improves the convenience and lifespan of the self-cleaning electrostatic adsorption dust removal equipment.

[0017] Meanwhile, there is a voltage difference between the discharge element and the adsorption element, and an electric field is formed between them. The electric field helps to decompose the gas, and this self-cleaning electrostatic adsorption dust removal equipment can also play a certain deodorization role. Attached Figure Description

[0029] Example 1

[0030] This embodiment provides a self-cleaning electrostatic adsorption dust removal device, which includes a discharge element and an adsorption element. The discharge element is connected to the negative terminal of a power source, and the adsorption element is grounded or connected to the positive terminal of the power source. A gap is left between the discharge element and the adsorption element, through which the dust-laden gas to be treated passes. The surface of the adsorption element facing the discharge element is an adsorption surface 3, on which a water film is disposed. A water supply system is provided on the adsorption element to supply water to the water film, and the water film is grounded or connected to the positive terminal of the power source.

[0031] In practical use, the discharge element discharges, creating a voltage difference between it and the adsorption element. Dust and other impurities combine with electrons to form negatively charged dust. Under the influence of the electric field, the negatively charged dust moves towards the adsorption element, where a water film adsorbs it. As the water film continues to flow downwards, electrons from the negatively charged dust are conducted to ground or the positive terminal of the power supply, while the dust remains on the water film. As the water film flows downwards and drips off, the dust detaches from the adsorption element. This design allows the adsorption element to automatically clean itself of adsorbed dust and other impurities, preventing the accumulation of various impurities on the adsorption element. This eliminates the need for manual cleaning of deposits, improving the convenience and lifespan of the self-cleaning electrostatic adsorption dust removal equipment.

[0032] Specifically, in this embodiment, negatively charged dust, i.e., dust and other impurities carrying electrons, should be adsorbed by a water film. To prevent dust and other impurities from being adsorbed in areas without a water film, the adsorption surface 3 is an insulator that does not absorb negatively charged dust. This insulator replaces conventional sheet metal in the prior art, as it does not corrode and is less expensive than sheet metal.

[0033] Specifically, in this embodiment, in order to collect dust and other impurities dripping with the water film, a water droplet pool 4 is provided at the lower part of the adsorption element. Water droplets on the adsorption element fall into the water droplet pool 4, and the water droplet pool 4 is connected to a wastewater treatment system 14. Meanwhile, in this embodiment, an exhaust gas inlet 5 is connected to the lower part of the gap between the discharge element and the adsorption element.

[0034] Specifically, in this embodiment, the specific style of the adsorption element is also disclosed: the adsorption element is a hollow tube 2, the discharge element is a discharge rod 1 disposed inside the hollow tube 2, the adsorption element is a hollow tube 2, the hollow tube 2 can be a round tube, and the self-cleaning electrostatic adsorption dust removal device can be composed of multiple hollow tubes 2 arranged side by side.

[0035] Specifically, in this embodiment, the water supply system includes an outer plate 6 outside the adsorbent. The outer plate 6 and the outer wall of the adsorbent form a water storage cavity 7. That is, the adsorbent should be plate-shaped, which can be a flat plate or a ring plate. The outer plate 6 is provided on the back side of the adsorption surface 3, that is, on the outside of the adsorbent. There is a gap between the outer plate 6 and the adsorbent. The outer plate 6 and the adsorbent form a water storage cavity 7, which is the water storage cavity 7. The water storage cavity 7 is connected to a water supply device that supplies water to the water storage cavity 7. A water outlet is provided on the upper part of the adsorbent. Water in the water storage cavity 7 seeps into the adsorption surface 3 of the adsorbent from the water outlet, that is, from the back side of the adsorbent into the adsorption surface 3, and forms a downward flowing water film on the adsorption surface 3.

[0036] More specifically, in this embodiment, in order to make the water at the bottom of the adsorbent drip rather than form a continuous flow, it is necessary to reduce the water output of the water outlet. For this purpose, a flexible cloth is provided at the height of the water outlet. The flexible cloth is fixed to the inner or outer wall of the adsorbent. Water seepage through the flexible cloth can slow down the water flow and facilitate the formation of a water film.

[0037] More specifically, in this embodiment, the water supply system includes a water storage tank 8, which is connected to the lower part of the water storage chamber 7. A first water level controller 15 is installed on the water storage tank 8 to control the water level inside. The first water level controller 15 is connected to a first water pump 16 for pumping water into the water storage tank 8. When the first water level controller 15 detects that the water level is too low, it controls the first water pump 16 to start and supply water to the water storage tank 8. When the first water level controller 15 detects that the water level has reached a preset value, it controls the first water pump 16 to shut down and stop supplying water. By controlling the water level in the water storage tank 8 in this way, and since the water storage tank 8 and the water storage chamber 7 are connected, the water level in the water storage tank 8 and the water level in the water storage chamber 7 are the same. Therefore, controlling the water level in the water storage tank 8 can control the water level in the water storage chamber 7.

[0038] Specifically, in this embodiment, a small amount of dust and other impurities may accumulate on the discharge component. This embodiment provides a cleaning method for the discharge component. Cleaning should be done after power is cut off, i.e., after the power is turned off, to avoid leakage problems. Of course, it can also be cleaned by dripping water while the power is on. This embodiment preferably cleans after power is cut off. The water supply system also includes a discharge component flushing component, which includes a water supply pipe. The water supply pipe is a water-cutting insulating pipe 9, and the outlet of the water-cutting insulating pipe 9 is located at the upper part of the discharge component. A pneumatic water control valve 10 is installed on the water-cutting insulating pipe 9. The aforementioned water-cutting insulating pipe 9 ensures that the internal water flow is interrupted after the water supply pipe is cut off, preventing current from being conducted to the water supply system through the water supply pipe. To further block the current, this embodiment uses an activation water control valve to control the on / off of the water supply pipe.

[0039] More specifically, in this embodiment, the water-cutting insulating pipe 9 is connected to a water storage tank 11 that is higher than the discharge element. The water storage tank 11 is connected to the water storage tank 8 of the water supply system. A second water level controller 17 is installed inside the water storage tank 11. The second water level controller 17 is connected to a second water pump 18 for pumping water from the water storage tank 8 to the water storage tank 11. The water supply pipe between the water storage tank 11 and the water storage tank 8 is also preferably a water-cutting insulating pipe 9 to avoid contact failure. When the second water level controller 17 detects that the water level is too low, it controls the second water pump 18 to start and supply water to the water storage tank 11. When the second water level controller 17 detects that the water level has reached a preset value, it controls the second water pump 18 to shut down and stop the water supply. The water level of the water storage tank 11 is controlled in the above manner.

[0040] Specifically, in order to ground the water film or connect it to the positive terminal of the power supply, a conductive plate is provided in the lower middle part of the adsorption member, and the conductive plate is grounded or connected to the positive terminal of the power supply; the water film passes through the conductive plate.

[0041] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
