Description

Modular Electrostatic Precipitator

The present invention relates to a modular electric dust collector, and more particularly, to a modular electric dust collector that is easy to install and maintain by modularizing a dust collecting plate that collects particles charged by the force of an electric field.

The electrostatic precipitator is a device for purifying air by charging contaminants such as dust contained in the air and collecting the charged contaminants on a dust collecting plate by electrostatic force.

The dust collector constituting the electric dust collector is divided into a first plate to which a high voltage is applied and a second plate to which a polarity opposite to that of the high voltage is applied or grounded. In general, a plurality of first plates and a plurality of second plates are alternately arranged to be spaced apart. It is configured to increase dust collection efficiency.

Electrostatic precipitators have been widely used in small air purifiers, but recently they are also used to purify air in large spaces or large facilities such as subway stations, semiconductor manufacturing facilities, and thermal power plants. As the processing capacity of a large-sized electric dust collector increases, the size of the dust collecting plate used inevitably increases, and the number of dust collecting plates also increases.

As the size of the dust collecting plate increases and the number of dust collecting plates increases, the weight of the dust collecting unit becomes heavy and assembly becomes difficult. In addition, when some dust collecting plates are damaged due to sparks, etc., it is difficult to find and replace the damaged points, so there is a problem of maintenance.

In addition, the conventional dust collecting plate is generally made of a metal plate, but in the case of a metal plate such as SUS, there is a problem that it can be easily corroded when air containing a corrosive gas is targeted, such as semiconductor equipment. In addition, when the size (area) of the dust collecting plate is increased, it is difficult to manufacture it thinly as a metal plate and the weight becomes heavy. Recently, a conductive non-metal plate using carbon fiber reinforced plastic (CFRP) is being applied to a corrosive environment. It has excellent corrosion resistance, but has a disadvantage in that it is less economical than the existing SUS. Accordingly, recently, a film-type dust collecting plate manufactured by coating a conductive material such as carbon on a base film has been used. In this case, it is possible to solve the problems of the above-described metal plate type dust collecting plate and CFRP type dust collecting plate because it has strong corrosion resistance, light weight, low manufacturing cost, and mass production. Since the film-type dust collecting plate is light in weight, it can be fixed by drilling a hole in the dust collecting plate and inserting a plurality of dust collecting plates into a long rod at regular intervals. In addition, the dust collecting plate may be electrically connected through the rod through the contact between the inside of the hole and the outside of the rod. However, the contact between the inside of the hole and the outside of the rod is not stable. For assembly, there is a fine but tolerance between the hole and the rod of the dust collecting plate, and if the dust collecting plate is loosened and shakes due to vibration or aging due to use, the electrical connection between the dust collecting plate and the rod becomes more unstable, causing sparks. may occur. Therefore, it is necessary to improve the dust collecting efficiency by stably electrically connecting the rod and the dust collecting plate.

In addition, as the size of the electric dust collector increases, the amount of electricity applied to the dust collecting plate also increases. If contaminants enter the structure that supplies high voltage to the dust collecting plate and the insulation is broken, it may cause overall problems in the operation of the electrostatic precipitator and may cause a fire due to sparks.

Accordingly, an object of the present invention is to solve the problems of the prior art, and it is easy to scale up the dust collecting plate to a large electric dust collector by modularizing the dust collecting plate, and the modular electric dust collector is easy to assemble and maintain. is to provide.

In addition, an object of the present invention is to solve such a problem in the prior art, by fixing a conductive washer to at least one side of the dust collecting plate so that the dust collecting plate is not shaken, and the contact area between the fixed rod and the dust collecting plate through the washer. It is intended to provide a dust collecting plate fixing structure of an electric dust collector capable of electrically connecting the dust collecting plate more stably.

In addition, an object of the present invention is to solve such a problem in the prior art, by separating a dust collecting room where dust is collected and an insulating room for applying a high voltage, and forming a partition wall between the dust collecting room and the insulating room as a double partition spaced apart. An object of the present invention is to provide an electric dust collector which prevents the inflow of contaminants from the dust collecting room to the insulating room and thereby prevents the insulation from being destroyed.

The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

According to the modular electric dust collector of the present invention as described above, it is easy to scale up the electric dust collector by modularizing the dust collector.

In addition, there are advantages in that assembly is simple and maintenance is convenient even if it is manufactured in a large size.

According to the structure of fixing the dust collecting plate of the electric dust collector of the present invention as described above, the dust collecting plate is fixed without shaking by using a washer part, and the contact area between the fixed rod and the dust collecting plate is increased through the dust collecting plate and the washer part, so that the dust collecting plate is more stable.

In addition, there is an advantage in that the dust collecting plate is more firmly fixed through the contact reinforcement and electricity can be stably transmitted from the fixed rod to the dust collecting plate.

According to the electrostatic precipitator of the present invention as described above, the dust collecting room in which the dust collecting plate is disposed and the insulating room for applying a high voltage to the dust collecting plate are spatially separated, and the barrier between the dust collecting room and the insulating room is composed of spaced double barriers. Thus, there is an advantage in that it is possible to effectively block the breakdown of insulation by blocking the inflow of contaminants from the dust collection room to the insulation room.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention pertains It is provided to fully inform those who have the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the present invention will be described with reference to the drawings for explaining a modular electric dust collector according to embodiments of the present invention.

It is a side view, and FIG. 5 shows the connection structure of the plate according to the present invention, and FIG. 6 is a view showing the structure of the double partition wall between the dust collecting room and the insulating room.

The electrostatic precipitator according to the present invention moves the charged particles by the force of an electric field generated between the first plate 110a to which a high voltage is applied and the second plate 110b to which a voltage having a polarity opposite to that of the high voltage is applied or grounded. It collects dust on the dust collecting plate 110 . In the following description, the second plate 110b will be described as being grounded.

The electric dust collector according to an embodiment of the present invention may include a housing 100 and a dust collection module 200 .

As shown in FIGS. 1 and 2 , the housing 100 forms the outer shape of the electric dust collector. In this embodiment, a dust collecting room for performing electric dust collection is formed in the center of the housing 100, and insulating rooms for applying a high voltage to the first plate 110a of the dust collecting module 200 are formed on both sides of the dust collecting room to collect dust Room and space can be separated.

A high voltage rod 182 extending into the dust collecting room to apply a high voltage to the dust collecting module 200 and an insulator 180 for insulation may be accommodated in the insulating room. A pipe 190 receiving air from the outside may be formed above the insulating room. The air introduced into the insulation room flows into the dust collection room through the

partition walls

107 and 108 between the insulation room and the dust collection room through which the high voltage rod 182 penetrates to prevent moisture from forming inside and outside the insulation room and from the dust collection room. Prevent the ingress of contaminated particles into the insulation room and break the insulation.

The lower and upper sides of the dust collecting room are opened, so that polluted air is introduced from the lower side, and purified air can be discharged through the dust collecting room to the upper side.

The dust collecting module 200 may include a plurality of first plates 110a, a plurality of second plates 110b, a first fixing rod 120a, and a second fixing rod 120b. In the present invention, a plurality of dust collecting modules 200 as shown in FIG. 3 may be modularized and provided in a plurality of dust collecting rooms. In this embodiment, the description is given as an example that two dust collecting modules 200 are disposed on the left and right, but a plurality of dust collecting modules 200 may be disposed in the front and rear directions as well.

By modularizing and installing the

dust collecting plates

110a and 110b in this way, it is easy to scale up to a large electric dust collector, and when a failure occurs due to sparks in the dust collecting plate 110 at a specific point, the dust collecting plate 110 Since the dust collection module 200 including a replacement and repair can be performed, maintenance is convenient.

A high voltage may be applied to the dust collecting module 200 on the left through the insulating room on the left, and a high voltage may be applied to the dust collecting module 200 on the right through the insulating room on the right, respectively.

A detailed configuration of the dust collecting module 200 will be described.

The first plate 110a and the second plate 110b are alternately spaced apart from each other. An electric field is formed between the first plate 110a to which a high voltage is applied and the second plate 110b to be grounded. Particles charged with anions or cations move in different directions by the force of the electric field to move in different directions to the first plate ( 110a) or may be collected on the second plate 110b.

In addition, the electrostatic precipitator according to the present invention can be used as a large electrostatic precipitator, such as a device for removing fine dust contained in exhaust gas of a thermal power plant. Accordingly, the dust collecting plate 110 may be manufactured in a large size having a large dust collecting area. In the following description, the dust collecting plate 110 used in the present invention will be described with reference to FIGS. 7 to 9 . However, not only the dust collecting plate 110 described in FIGS. 7 to 9 can be used in the electrostatic precipitator of the present invention, and other conventionally known dust collecting plates may also be used in the electrostatic precipitator of the present invention.

7 is a cross-sectional view of a dust collecting plate according to an embodiment of the present invention, FIG. 8 is a modification of FIG. 7 , and FIG. 9 shows a manufacturing process of the dust collecting plate of FIGS. 7 and 8 .

As shown in Figure 7, the film-type dust collecting plate 110 according to an embodiment of the present invention is bonded along the edge of the film portion and the film portion in the form of a film including an electrically conductive conductive layer 112. It may be configured to include a fixed frame 115 made of a rigid material.

The film part includes a base film 111 that is a flexible plastic, an electrically conductive conductive layer 112 formed on the base film 111, and a coating layer 113 formed of an insulating material on the conductive layer 112. can be configured. The conductive layer 112 may be formed by a carbon coating on the base film 111 .

FIG. 8 shows a modification of FIG. 7 , wherein the conductive layer 112 and the coating layer 113 are formed only on one side of the base film 111 in FIG. 7 , whereas in FIG. 8 , the conductive layer 112 . There is a difference in that the coating layer 113 is formed on both sides of the base film 111 .

The coating layer 113 is formed on the conductive layer 112 , but a conductive part 114 in which a portion of the conductive layer 112 is exposed may be formed. The conducting portion 114 is preferably formed on one edge of the film portion so that one edge of the conductive layer 112 is exposed. By bonding the fixing frame 115 to the edge of the film part, the conductive layer 112 may be electrically connected to the outside through the fixing frame 115 . The configuration of electrically connecting the conductive layer 112 to the outside through the fixing frame 115 may be better understood through the description of the method of manufacturing the dust collecting plate 110 with reference to FIG. 9 . For reference, FIGS. 7 and 8 may be cross-sectional views taken along line A-A of FIG. 9 .

The manufacturing method of the dust collecting plate 110 includes the steps of preparing a film portion including an electrically conductive conductive layer 112 (S210 to S230) and bonding a rigid frame 115 along the edge of the film portion. It may include a step (S240) of making.

The step of preparing the film part in the form of a film may correspond to S210 to S230 in FIG. 9 . First, a base film 111 in the form of a film is prepared (S210), and an electrically conductive conductive layer 112 is formed on the base film 111 (S220). The base film 111 may be a plastic film having flexibility. For example, a PET film, a PVC film may be used. At this time, the conductive layer 112 may be formed only on one side of the base film 111 as shown in FIG. 7 , and the conductive layer 112 on both sides of the base film 111 as shown in FIG. 8 . ) may be formed.

In addition, the conductive layer 112 is preferably formed to be slightly smaller than the base film 111 . That is, the edge of the conductive layer 112 is formed inside the edge of the base film 111 so that the edge of the conductive layer 112 is not exposed to the outside. This prevents sparks from being generated when a high voltage is applied to the conductive layer 112 and makes it electrically stable.

In this case, the conductive layer 112 may be formed through carbon coating. Although carbon (C) is a non-metal, it has electrical conductivity and is so light that it cannot be compared with metal. In addition, there is also an advantage of having strong corrosion resistance to corrosive gas. Furthermore, it can be easily manufactured by coating the base film 111 and has the advantage that the manufacturing cost is low.

Next, a coating layer 113 is formed with an insulating material (eg, plastic) on the conductive layer 112 ( S130 ). The coating layer 113 is formed to have the same size as the base film 111 , and the conductive layer 112 is formed between the coating layer 113 and the base film 111 , and as described above, the edges of the conductive layer 112 are It is desirable not to be exposed to the outside. The conductive layer 112 formed of the carbon coating has strong corrosion resistance by the conductive layer 112 itself, but may have stronger corrosion resistance by the coating layer 113 .

In the case of FIG. 8 , the conductive layers 112 are formed on both sides of the base film 111 , and the coating layers 113 are respectively formed on the conductive layers 112 on both sides.

At this time, as shown, the coating layer 113 is formed so that a conductive part 114 through which a part of the conductive layer 112 is exposed is formed. The conductive part 114 may be positioned at one edge of the conductive layer 112 on which the fixing frame 115 is formed. A portion of the conductive layer 112 may be exposed by the conductive portion 114 , which is a region where the coating layer 113 is not formed, to electrically connect the conductive layer 112 from the outside.

In this way, a film-shaped film part including the electrically conductive conductive layer 112 is prepared, and then the fixing frame 115 made of a rigid rigid material is bonded along the edge of the film part (S240). The fixing frame 115 may be formed by bonding on both sides of the edge of the film unit, but is not limited thereto and may be formed by mechanical coupling.

Therefore, in the present invention, since the shape of the dust collecting plate 110 can be maintained by the fixed frame 115 made of a rigid material, a large dust collecting plate 110 in the form of a film having a width of 1 m or more that is not easily bent or bent can be implemented. have.

At this time, the fixing frame 115 is bonded to the conductive layer 112 through the conductive part 114 formed on one edge of the conductive layer 112 , and the conductive layer 112 is removed from the outside through the fixing frame 115 . It can be electrically connected. That is, the fixing frame 115 is formed of an electrically conductive material, and a high voltage is applied or grounded to the fixing frame 115 to connect the dust collecting plate 110 to the first plate 110 to which the high voltage is applied or the second plate to be grounded. (110b) can be used.

Referring to the configuration of the dust collecting module 200 again, the first fixing rod 120a fixes the plurality of first plates 110a to be spaced apart from each other, and applies a high voltage to the first plate 110a. In addition, the second fixing rod 120b fixes the plurality of second plates 110b to be spaced apart from each other and ground the second plate 110b. A structure for fixing the plurality of first plates 110a on the first fixing rod 120a and a structure for fixing the plurality of second plates 110b on the second fixing rod 120b are the same.

A fixing hole 118 into which the first fixing rod 120a is inserted is formed in the first plate 110a. When the first fixing rod 120a is inserted into the fixing hole 118, the inner surface of the fixing hole 118 and the outer surface of the first fixing rod 120a come into contact with each other to generate a high voltage applied to the first fixing rod 120a. It can be transferred to the first plate (110a). In this case, the fixing hole 118 may be formed in the fixing frame 115 of the first plate 110a to apply a high voltage to the conductive layer 112 through the fixing frame 115 .

In addition, the first fixing rod 120a may be inserted into the outer space maintaining portion 128 for maintaining a constant separation distance between the adjacent first plate (110a) may be disposed. Both ends of the spacing maintaining unit 128 may be in contact with the first plate 110a to maintain a constant separation distance between the adjacent first plates 110a. At this time, it is preferable that the gap maintaining portion 128 is formed of an insulator.

For reference, the second plate 110b disposed between the first plate 110a is not shown in FIG. 5, but as shown in FIG. 4, the first fixing rod 120a is connected to the second plate 110b. Interference prevention holes 119 may be formed in the second plate 110b so as not to be interfered with so that the first fixing rods 120a are inserted to be spaced apart.

The first plate 110a is inserted into the first fixing rod 120a and is electrically connected through contact between the inner surface of the fixing hole 118 and the outer surface of the first fixing rod 120a, and the first fixing rod 120a A high voltage applied thereto may be transferred to the first plate 110a. When inserting the first fixing rod 120a into the fixing hole 118, there is a fine tolerance between the first fixing rod 120a and the fixing hole 118 for the convenience of assembly. Therefore, when the first fixing rod 120a is inserted into the fixing hole 118 of the first plate 110a, the diameter of the fixing hole 118 and the first fixing rod 120a do not exactly match, so the fixing hole 118 ) It is possible to make line contact at one point rather than the entire contact along the circumference of the inner surface. Accordingly, the contact point between the inner surface of the fixing hole 118 and the outer surface of the first fixing rod 120a is small, so that the contact between the first fixing rod 120a and the first plate 110a may be unstable. Furthermore, the fixing of the first plate 110a on the first fixing rod 120a is released even by vibration and aging according to the operation of the electric dust collector, so that the contact between the first fixing rod 120a and the first plate 110a is reduced. may become unstable.

Accordingly, the washer part 125 is inserted into the first fixing rod 120a and fixed to one side of the first plate 110a to fix the position of the first plate 110a. At this time, as shown in FIG. 5 , it is preferable that the washer parts 125 are respectively fixed to both sides of the first plate 110a to firmly fix the position of the first plate 110a.

The first fixing rod may be electrically connected to the first fixing rod 120a through the inner surface of the washer portion 125 into which the first fixing rod is inserted, and the first fixing rod is in contact with the first plate 110a through one side of the washer portion 125 to make the first The high voltage applied to the first fixing rod 120a may be transmitted to the first plate 110a.

In this way, by increasing the contact area between the first fixing rod 120a and the first plate 110a through the washer portion 125, more stably electric power between the first fixing rod 120a and the first plate 110a is increased. can connect In addition, by arranging washer portions 125 on both sides of the first plate 110a to firmly fix the position of the first plate 110a, the first fixing rod 120a and the first plate 110a are caused by vibration and aging. ) can be prevented from becoming unstable.

A plurality of first fixing rods 120a for fixing the first plate 110a may be disposed on the fixing frame 115 . In this embodiment, as shown in FIG. 4, the first plate 110a is fixed by using three pairs of first fixing rods 120a from top to bottom.

As shown in FIG. 4 , the first plate 110a is disposed to protrude further downward compared to the second plate 110b, and the second plate 110b is upwardly compared to the first plate 110a. formed to protrude more. In addition, the width of the first plate 110a is formed to be wider than the width of the second plate 110b.

One end of any one of the first fixed rods 120a (in the drawing, the first fixed rod 120a located at the uppermost end of the first fixed rods 120a) is coupled to the high voltage load 182 extending from the insulating room and is coupled to the high voltage load. Electricity may be transmitted and supported through 182 .

As shown in FIGS. 2 and 6 , the

partition walls

107 and 108 between the insulating room and the dust collecting room may be formed of

double partition walls

107 and 108 spaced apart from each other. Through-

holes

1071 and 1081 larger than the diameter of the high voltage rod 182 may be formed in the

double partition walls

107 and 108 so that the high voltage rod 182 can be inserted to be spaced apart. When the spacing between the through

holes

1071 and 1081 and the high voltage rod 182 is small, contaminants may accumulate in the gap between the through

holes

1071 and 1081 and the high voltage rod 182 may cause a fire due to a spark due to the high voltage. In addition, when the distance between the high voltage rod 182 and the through-

holes

1071 and 1081 is large, contaminants from the dust collection room may easily flow into the insulation room. If the insulation room is contaminated, the insulation will be broken, and the system stability of the electrostatic precipitator will be lowered and a fire may occur. Therefore, it is preferable that the spacing between the high voltage rod 182 and the through

holes

1071 and 1081 is designed to have an appropriate size.

Among the

double partition walls

107 and 108, when the partition located on the insulating room side is called the first partition wall 107 and the partition wall located on the dust collecting room side is called the second partition wall 108, the second partition wall 108 Contaminants may flow into the first partition wall 107 only through the through hole 1081 formed in the . Therefore, the amount of contaminants flowing into the space between the first and

second barrier ribs

107 and 108 may be very small, and it is possible to prevent the contaminants from entering the insulation room and blocking the insulation. .

In addition, the air introduced into the insulating room through the pipe 190 may be introduced into the dust collecting room through the through

holes

1071 and 1081 . If the flow rate of the air flowing into the dust collecting room is high, the dust collecting plate 110 is shaken by applying pressure to the dust collecting plate 110 to generate sparks. It is possible to further block the inflow of contaminants from the dust collection room into the insulation room through the through-

holes

1071 and 1081 by the flow of the incoming air.

In addition, it is possible to lower the humidity around the high voltage rod 182 by the air flowing into the insulation room, thereby preventing sparks from occurring. Therefore, it is preferable that the air flowing into the insulation room is high-temperature air or the temperature is raised in the insulation room to effectively lower the humidity.

Furthermore, the high voltage rod 182 may be coated with an insulating material. For example, coating around the high voltage rod with TEFLON may further prevent sparks from occurring when a high voltage is applied through the high voltage rod 182 .

An air control unit 109 may be disposed on the partition wall 107 . As shown in FIG. 6 , the air control unit 109 is fixed to the through hole 1071 of the first partition wall 107 , and a through hole 1091 through which the high voltage rod 182 passes is formed in the center. Therefore, as described above, the air inside the insulating room can be introduced into the dust collecting room through the through hole 1091, and it is recommended to maintain an appropriate distance between the through hole 1091 and the high voltage rod 1091. desirable.

An inclined surface facing the high voltage rod 182 is formed on the inner surface in front of the passage hole 1091 in the direction in which air flows from the insulating room to the dust collecting room. That is, the cross-sectional area of the passage hole 1091 is gradually reduced toward the front by the inclined surface, and the flow of air is directed toward the high voltage rod 182 penetrating the center of the passage hole 1091 by the inclined surface, and the dust collecting room is headed towards Accordingly, it is possible to more effectively prevent insulation breakdown due to moisture filling the high voltage load 182 .
