Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electrostatic precipitator,

[0001] The present invention relates to an electrostatic precipitator equipped with a spray device for forming a water film, and more particularly, to a wet electrostatic precipitator in which a spray tube for forming a water film is formed on an upper part of a dust collecting plate, A cleaning water supply tube is provided on the dust collecting plate and the spray tube and the pressure is appropriately adjusted so that the washing water sprayed through the spray tube flows down on the dust collecting plate and the dust collecting function is stably performed, To an electrostatic precipitator equipped with a spray device for forming a water film which enables continuous operation of an electrostatic precipitator without breakdown of insulation between a discharge electrode and a dust collecting plate even in a continuous situation.

At present, awareness of harmfulness of fine dusts has been raised, and interest in techniques for removing fine dusts from various plants is increasing.

Fine dusts are very harmful because they contain various kinds of heavy metals, polyunsaturated aromatic hydrocarbons (PAHs), and mercury, besides they cause health problems because of their small size. It is associated with sulfur oxides to generate fog, which causes visibility disorder, and causes various biological and environmental problems. In order to remove such fine dust, a dry or wet electrostatic precipitator is employed at the rear end of the exhaust gas treatment device discharged from various plants.

The distinction of the dry or wet electrostatic precipitator is determined depending on whether or not water is used to remove the dust collected on the dust collecting plate. FIG. 1 shows a general type of electrostatic precipitator, and FIG. 2 shows a wet electrostatic precipitator.

In the case of the dry electrostatic precipitator, as shown in FIG. 1, the dust adhering to the dust collecting plate 10 is removed through mechanical impact by the chattering device 30. In the wet electrostatic precipitator, as shown in FIG. 2, A large amount of water is sprayed on the surface of the dust collecting plate 10 so that the dust collected through the water film 50 on the surface of the dust collecting plate 10 is washed down to the bottom.

In general, a wet electrostatic precipitator is effective for removing fine dust. In the case of a dry electrostatic precipitator, there is a fear that the dust collected when a mechanical impact is applied to the dust collecting plate 10, The wet dust collector is relatively clean due to the fact that the collected dust is cleaned with water. Therefore, the wet electrostatic precipitator has been actively developed for removing fine dust.

However, although the wet electrostatic precipitator is effective for removing fine dust, if water is sprayed during charging of the electrostatic precipitator, the electrical insulation between the dust collecting plate and the discharge electrode is destroyed. Accordingly, continuous operation of the electrostatic precipitator is not possible and intermittent charging must be performed. As a result, stable operation of the electrostatic precipitator is hindered, which is a great obstacle to widening the range of the electrostatic precipitator.

In the case of a wet electrostatic precipitator, since the gas temperature is irregularly dropped due to intermittent water injection, application to a gas having a high temperature is limited. In the case of spraying water for cleaning the dust collecting plate, A separate mist removing device is additionally required at the downstream end thereof, so that the gas pressure loss is unnecessarily lost, and there is a problem that the initial investment cost increases due to the additional configuration.

In order to solve the above problem, a wet electrostatic precipitator capable of continuous charging has been commercialized recently. A typical example thereof is a method of forming a thin water film on the surface of a dust collecting plate to remove dust immediately after dust collection. The branching method is an example.

1. Method of spraying water into fine particles on the front side of a wet electrostatic precipitator to cause the fine particles to collect on the surface of the dust collecting plate

2. Method of spraying onto the dust-collecting plate by using a fan spray nozzle (spray nozzle)

3. By regularly drilling a hole in the upper part of the dust collecting plate, water flows down from the water pipe located at the rear side

The above methods are all commercially used, and the advantages and disadvantages of each method are shown in Table 1.

system Advantages Disadvantages Fine particle spraying method Reduced initial investment Water particles are almost collected at the early stage of dust collection, Use fan spray nozzles It is possible to form an even film on the surface of the dust collecting plate. 1. High water usage
2. Mist is generated when pressure and injection angle adjustment fails
3. If spraying angle is changed, water can not be sprayed on the dust collecting plate and fall down directly. Water injection through the upper hole of the dust collector Water film formation with small amount of water 1. Can not form water film when pressure control fails
2. In the case of large facilities, it is difficult to keep the water injection quantity constant due to the impossibility of forming uniform pressure
3. The mechanical strength is reduced due to the very dense spacing of the holes.
4. Increase initial investment by using only one side of collecting plate

In spite of the relatively long history of wet electrostatic precipitator, it has been used for small facilities because it has the above disadvantages. In order to overcome the limit of scale and to expand application range, A wet electrostatic precipitator that is simple to install and low in cost needs to be developed.

According to the present invention, the cleaning water supply tube, the spray tube, and the dust collecting plate are integrated to facilitate the installation of the electrostatic precipitator, and a certain degree of pressure is constantly formed in the cleaning water supply pipe, Accordingly, unevenness due to the position of the spray hole is minimized, so that it can be applied to both a compact and an enlarged electrostatic precipitator.

Accordingly, the installation is easy regardless of the skill of the operator, The dust collecting plate has a structure in which the dust collecting tube supports the dust collecting plate, thereby preventing the formation of a water film on the dust collecting plate, even when the dust collecting plate is twisted during operation.

According to the present invention, water droplets are prevented from splashing even when the water pressure is relatively high, because the cleaning water jetting holes are opposed to the dust collecting plate in a relatively densely spaced space, and thus stable operation can be performed.

According to the present invention, when the process gas is moved from the lower part to the upper part, the recovery tray installed at the lower part of the dust collecting plate functions as a baffle, and the dust can be uniformly distributed, The efficiency can be further improved.

The present invention is not limited to the case where a plurality of the planar type dust collecting plates 10 and the dust collecting plates 10 are provided in a state spaced apart from the collecting plate 10 by a predetermined distance A wet electrostatic precipitator including a plurality of discharge electrodes 20 is provided with a spray device for forming a water film. FIG. 4 shows a plurality of the dust collecting plates 10 arranged in a row, The washing water can be supplied to each of the dust collecting plates in a state where the washing water 100 is separated from the dust collecting plate 10 by a predetermined distance. In FIG. 3, only one dust collecting plate 10 is formed in the lower part of the washing water supplying pipe 100 for the sake of convenience. However, the dust collecting plate 10 may be provided in the cleaning water supplying pipe 100, The washing water supply pipe 100 and the series of dust collecting plates may be formed continuously in the left and right direction.

In the present invention, a spray tube 300 is coupled to an upper portion of the dust collecting plate 10, and the spray tube 300 receives washing water from the washing water supply tube 100 and cleans the surface of the dust collecting plate 10 So that the water flows from the upper part to the lower part. 3 and 4, the washing water is supplied from the washing water supply pipe 100 to the spray pipe 300 through the connection pipe 200, So that the cleaning water supply pipe 100 and the spray pipe 300 can be easily connected to each other. Further, the cleaning water supply pipe 100 and the spray pipe 300 can be easily connected to each other.

The washing water supply pipe 100 is provided with a pressure control valve 110 for controlling the water pressure of the washing water sprayed to the dust collecting plate 10 through the spray pipe 300. A plurality of injection holes 310 having a predetermined diameter are formed in the injection tube 300 and a plurality of injection holes 310 are continuously formed at predetermined intervals over the length of the injection tube 300. The injection pipe 300 used in the present invention may have various shapes such as a circular or square cross section, but may be formed as shown in FIG. 6 when it is formed in a rectangular shape. In this case, the injection holes 310 are continuously formed at the lower part of the rectangular spraying tube 300 at regular intervals.

In the present invention, the injection tube 300 may be formed on only one side of the upper portion of the dust collecting plate 10, or may be formed on both sides of the upper side of the collecting plate 10, Are formed with a predetermined distance from the dust collecting plate (10) over the transverse length of the dust collecting plate (10). 6, an injection hole 310 is formed in a side surface of the injection tube 300 in contact with the dust collecting plate 10 to adjust the gap between the dust collecting plate 10 and the injection tube 300, The gap means 320 is provided on the side surface and the gap means 320 is formed at a position where the plurality of injection holes 300 formed continuously in the lower portion of the injection tube 300 are covered or not overlapped with each other, So that the jetting of the washing water to the washing liquid 10 is not disturbed.

6, a plurality of injection holes 310 and a gap means 320 are provided at a lower side of a side surface facing the dust collection plate 10 in a state where the injection tube 300 is formed of rectangular pipes . In the case where the injection tube 300 is formed of square pipe, it is relatively easy and simple to form the coupling with the dust collecting plate 10, so that the installation is easy regardless of the skill of the operator, There is an advantage that no trouble occurs in the formation of the water film of the dust collecting plate 10.

3, when the jetting tube 300 is directly coupled to both the upper and lower surfaces of the dust collecting plate 10, the rectangular jetting tubes provided on both sides of the jetting tube are disposed at the lower side of the jetting hole, A plurality of gap means are formed. The coupling between the dust collecting plate 10 and the injection tube 300 may be band-wise or weld-coupled, or may be mutually coupled by various other methods.

In the present invention, a cleaning water recovery tray 400 is further provided at the lower end of the dust collecting plate 10, and the cleaning water recovered through the recovery tray 400 is treated to remove fine dust contained therein And then reused through the supply of the cleaning water through the cleaning water supply pipe 100. The present invention is applicable to both the case where the process gas including fine dust moves horizontally with respect to the dust collecting plate or the case where the process gas vertically moves from the bottom to the top, And the dust collecting efficiency of the electrostatic precipitator can be further improved through the uniform distribution of the exhaust gas.

The injection pressure of the washing water sprayed through the plurality of spray holes 310 of each spray tube 300 can be collectively controlled by adjusting the pressure control valve 110 provided in the washing water supply pipe 100 . A certain amount of pressure is constantly formed in the cleaning water supply pipe 100 so that the amount of the cleaning water sprayed into the spray hole 310 is kept constant and the irregularity in accordance with the position of the spray hole 310 It is advantageous to be applicable not only to a small size but also to a large-sized electrostatic precipitator

According to the present invention, the washing water from the washing water supply pipe 100 is supplied to the spray pipe 300 through the connection pipe 200 connected to the cleaning water supply pipe 100, And is sprayed to the dust collecting plate at a constant pressure through a plurality of injection holes 310. The pressure is such that the injected washing water does not bounce after colliding against the dust collecting plate.

The present invention is characterized in that the washing water is sprayed straightly horizontally on the dust collecting plate 10 slightly spaced apart at regular intervals after spraying the washing water through the spray hole 310. In this case, The washing water is scattered after the washing water hits the dust collecting plate and the insulation between the discharge electrode 20 and the dust collecting plate 10 is not destroyed. In the present invention, the water pressure of the washing water sprayed through the spray hole 310 provided for each spray pipe 300 is uniformly adjusted through the pressure control valve 110 provided in the washing water supply pipe 100 , The structure of the apparatus is simplified, and maintenance is easy.

The plurality of injection holes 310 provided in the present invention may have various sizes depending on the capacity of the electrostatic precipitator, the water pressure applied thereto, and the like, but may have a diameter of about 1 to 5 mm. The interval between the injection holes 310 may be varied according to the injection amount of the washing water, the size of the injection hole, or the water pressure required for the electric dust collector, but is generally 2 to 100 times the diameter of the injection hole 310, So that the washing water injected through the injection hole 310 is superimposed on the dust collecting plate 10 so that dust collecting is performed while the surface of the dust collecting plate 10 is completely covered. According to the present invention, since the cleaning water jetting holes 310 are opposed to the dust collecting plate 10 in a relatively densely spaced space, water droplets do not splash even when the water pressure is relatively high, There are advantages.

The gap between the dust collecting plate 10 and the spray hole 310 is spaced apart by a gap unit 320. The gap may be varied depending on the spray amount of the washing water required for the electrostatic precipitator, But it is generally 0.02 to 10 times the diameter of the injection hole 310. This is because the gap is less than 0.02 times the diameter of the injection hole to prevent a situation where the washing water hits against the dust collecting plate 10 due to the water pressure and prevents the gap from exceeding 10 times the diameter of the injection hole, Thereby preventing a portion of the dust collecting plate 10 from flowing in the washing water.

According to the present invention, the injection tube 300 for forming a water film is directly coupled to the upper portion of the dust collecting plate 10, and the coupling is performed at a predetermined interval so that the injection holes 310 The dust can be collected in a state in which the washing water is discharged through the dust collecting plate 10 in a stable manner and the fine dust can be collected by the dust collecting tube 300 while the water pressure is properly controlled through the pressure regulating valve 110 The washing water is stably discharged through the discharge electrode 20 and the dust collecting plate 10, so that the dielectric breakdown between the discharge electrode 20 and the dust collecting plate 10 is not performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
