Description

Technology Field

[0001] The present invention relates to an electrostatic precipitator, and more specifically, to an electrostatic precipitator having a cleaning structure capable of efficiently and effectively removing particles, such as dust, collected in an electrostatic precipitator module. Background Technology

[0002] Air purifiers that capture fine dust need to remove the captured dust. If the appropriate time for dust removal is missed, the air purifier loses its effective capture function.

[0003] However, air purifiers that use filters require regular filter replacement, but the cost of the filters is a burden to the user.

[0004] Plasma-type air purifiers (electrostatic precipitators) apply high voltage to form a corona discharge and utilize the ions generated at that time to capture fine dust. The captured fine dust is mainly removed by water cleaning or mechanical methods. In particular, since cleaning is performed frequently in environments with high concentrations of fine dust, a simple and economical cleaning method is an important technology.

[0005] There are various cleaning technologies in air purifiers that utilize plasma.

[0006] When dust is collected in the collector, there are methods to remove the dust by applying impact to the collector using a tapping device, removing it by flowing water over the collector, or soaking the contaminated collector in a tank containing a cleaning solution (such as a neutral detergent) and then rinsing it. Alternatively, there is a method of cleaning by applying vibration.

[0007] However, the tapping method is not as effective for cleaning as other methods, and the water cleaning method has the disadvantage of requiring a separate water supply. In particular, electrostatic precipitators installed in tunnels require the installation of piping to supply water, and water cleaning is impossible in winter due to the risk of pipe freezing. Additionally, there may be areas where water does not reach due to defects such as nozzle clogging, and dust sludge remains and accumulates in the drainage system, which becomes a factor in re-entrainment.

[0008] Therefore, there is a need to develop an electrostatic precipitator that can be used regardless of external temperature and can efficiently and effectively remove captured dust. Prior art literature

[0035] Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings. In the description with reference to the accompanying drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof are omitted.

[0036] An electrostatic precipitator having a cleaning structure according to one embodiment of the present invention relates to an electrostatic precipitator having a cleaning structure capable of efficiently and effectively removing particles, such as dust, collected in an electrostatic precipitator module.

[0037] FIG. 1 is a perspective view of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0038] An electrostatic precipitator (1000) having a cleaning structure according to one embodiment of the present invention includes a housing (2000) and an electrostatic precipitator module (3000).

[0039] The housing (2000) is an outer casing of an electrostatic precipitator (1000) having a cleaning structure according to the present embodiment, and is configured to allow the electrostatic precipitator module (3000) to be attached and detached. The housing (2000) is inserted and positioned by sliding movement of the electrostatic precipitator module (3000) and is separated by sliding movement. A through-hole (2100) is formed in the housing (2000) along the direction of sliding movement. In the present embodiment, the housing (2000) may be provided in a shape in which the upper and lower surfaces are penetrated along the height direction. That is, the sliding direction is the height direction of the housing (2000). In the present embodiment, the emitter module (100) of the electrostatic precipitator module (3000) is described as being positioned below the collector module (200), and thus the housing (2000) is also described as having an open upper and lower surface, but the positional relationship is merely an example and is not limited thereto.

[0040] FIG. 3 is a perspective view of a housing of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0041] The housing (2000) forms a receiving space by including a pair of first surfaces (2010) that are open in one area (i.e., a through-hole (2100) is formed) as the upper and lower surfaces, a pair of second surfaces (2020) that are the side surfaces connecting the pair of first surfaces (2010), and a pair of third surfaces (2030) as the front and rear surfaces. In this embodiment, an opening (through-hole (2100)) is formed in the pair of first surfaces (2010) so that it has an open shape along the height direction. This height direction is the sliding direction, i.e., the attachment / detachment direction, of the electrostatic precipitator module (3000).

[0042] In this embodiment, the electrostatic precipitator module (3000) is placed inside the housing (2000) but is not fixed to the housing (2000). This is to maximize the vibration application and cleaning efficiency by the vibration module (4000) (and the tapping module (5000)). Accordingly, a mounting hole (2040) is formed in the housing (2000). The mounting hole (2040) is formed so that the electrostatic precipitator module (3000) can be mounted on the housing (2000). In this embodiment, the mounting hole (2040) is formed on each of the second side (2020), which is a pair of sides, but it can also be formed on the third side (2030) if the electrostatic precipitator module (3000) can be mounted by being caught on the housing (2000), and its location is not limited.

[0043] And the housing (2000) can be provided to be fixed to the wall.

[0044] The housing (2000) can be electrically grounded by connecting it to a collector module (200) that is electrically grounded by a vibration module bracket (4200, see FIG. 9).

[0045] FIG. 4 is a perspective view of an electrostatic precipitator module having a cleaning structure according to an embodiment of the present invention, FIG. 5 is a perspective view of an emitter module having a cleaning structure according to an embodiment of the present invention, and FIG. 6 is an explanatory diagram between an emitter and a collector of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0046] The electrostatic precipitator module (3000) is configured to charge particles such as fine dust and air pollutants through ions generated through corona discharge to collect dust and to generate an ion wind, and includes an emitter module (100), a collector module (200), a non-collection section (300), a side plate (400), and an insulating wall (500).

[0047] In this embodiment, the emitter (130) of the emitter module (100) and the collector (210) of the collector module (200) are configured to charge particles such as fine dust and air pollutants through ions generated via corona discharge, thereby collecting dust and generating an ion wind. In this embodiment, the emitter module (100) is described as being positioned below the collector module (200) as an example. However, the positional relationship is merely an example and is not limited thereto.

[0048] The principles of corona discharge, ion wind, and dust collection are well known, so they will be explained briefly.

[0049] In the case of a wire-type emitter, when a voltage generally 10 to 30 kV higher than that of the collector is applied to the emitter, a positive corona discharge occurs in which positive ions are generated in the surrounding plasma region and move toward the collector. These moving positive ions continuously collide with neutral air molecules to generate an upward ion wind, causing dust particles to flow in from below and move upward. At this time, a charging phenomenon occurs where positive ions collide with dust particles and adhere to their surfaces. When these charged dust particles (positively charged) enter a collection unit to which an electric field is applied, the Coulomb force ( It is moved to the collector and captured by the electric field (q: charge, E: electric field). However, since ozone generated in the plasma region has no electrical polarity, it is discharged out of the electrostatic precipitator along the streamlines of the ion wind.

[0050] Emitters can be broadly classified into wire type and pin type, and the principle of the pin type emitter is the same as that of the wire type, except that it is a negative corona discharge with a voltage lower than that of the collector.

[0051] The emitter module (100) includes a support frame (110) and an emitter (130).

[0052] The support frame (110) is configured to support the emitter module (100) as a whole and is configured to receive high voltage from a power supply unit (not shown). The support frame (110) is provided in a plate shape and has a through hole (111) formed to allow air to pass through. In addition, a fixing frame (112) is formed in a side area of ​​the support frame (110), which is formed vertically from the support frame (110) and to which the emitter (130) is fixed. Since the fixing frame (112) is formed in a side area of ​​the support frame (110), the support frame (110) protrudes laterally from the fixing frame (112). The protruding area of ​​the support frame (110) is called the fixing part (113). The fixing part (113) can be fixed to an insulating wall (500).

[0053] The emitter (130) may be formed in a thin sheet strip or manufactured separately and fixed by being directly welded to the fixed frame (112) of the support frame (110). When formed in a thin sheet strip, the thin sheet strip is fixed to the fixed frame (112) and may be provided in multiple numbers and spaced apart from each other, and multiple emitters (130) may be formed spaced apart from each other on each thin sheet strip.

[0054] The emitter (130) can be broadly classified into wire type and pin type, and this embodiment is a pin type emitter. In this embodiment, the emitter (130) can be formed by etching a thin plate made of metal material. As an example, it can be formed by etching with an etching solution.

[0055] Since both the emitter (130) and the fixed frame (112) are made of metal, when a high voltage is applied to the support frame (110), a high voltage is applied to the emitter (130).

[0056] The collector module (200) is spaced apart from the emitter module (100), and in this embodiment, is positioned above the emitter module (100).

[0057] The collector module (200) includes a plurality of collectors (210) spaced apart from each other, and the collectors (210) can be connected to each other through a collector bracket (600).

[0058] The collector (210) is provided as a metal plate and is electrically grounded. In this embodiment, the collector (210) may be an aluminum plate. The collector (210) is configured to charge particles through corona discharge and generate an ion wind in relation to the emitter (130), and to collect charged particles in relation to the non-collection part (300). In other words, in this embodiment, the collector (210) and the collection electrode have an integrated structure.

[0059] And, the collector module (200) includes a plurality of collectors (210) spaced apart from each other, and among these, the collectors (210) at both ends are side plates (400).

[0060] Among the multiple collectors (210) of the collector module (200), the height of the collector (210) positioned at both ends is provided to be higher than the height of the other collectors (210). That is, the height of the side plate (400) is provided to be higher than the height of the other collectors (210). Furthermore, the heights of the other collectors (210), excluding the side plate (400), may be the same.

[0061] By forming the height of the side plate (400) higher than the height of the other collectors (210), sparks that may occur intermittently, especially when the height of the central collector (210) is high, can be prevented.

[0062] Multiple collectors (210) can be fixed by a collector bracket (600). The side plate (400), the collector bracket (600), and the collector (210) are electrically connected to each other, and can all be electrically grounded by grounding any one of them.

[0063] The non-collection unit (300) is configured such that charged particles are collected by the collector (210) when a high voltage is applied. That is, the collector (210) and the collection electrode have an integrated structure. The non-collection unit (300) includes a plurality of non-collection electrodes (310) and a fixed container (320), and the non-collection electrodes (310) and the collector (210) are arranged alternately.

[0064] The non-collecting electrode (310) includes two insulating films, a metal film, and a wire.

[0065] In this embodiment, the non-collecting electrode (310) has a metal film placed between two PVC films with a thickness of 0.5 mm. The metal film may be aluminum foil (Al foil) or a conductive film. If a conductive film is used, it may be a PET film with aluminum deposited on it.

[0066] The fixed container (320) is configured to fix a plurality of non-collecting electrodes (310) and at the same time ensure that the non-collecting electrodes (310) have a completely waterproof structure.

[0067] The non-collecting electrodes (310) can be fixed by the non-collecting bracket (700).

[0068] The non-collection bracket (700) is provided in a number corresponding to the collector bracket (600), and the upper and lower parts are each fixed to the collector bracket (600).

[0069] Accordingly, the non-collection electrode (310) can be fixed by sliding it into a slit formed in a plurality of non-collection brackets (700).

[0070] That is, multiple non-collecting electrodes (310), each fixed by a fixed container (320), are slidably inserted together, making fastening and separation easy, and maintenance is also easy because they have a completely waterproof structure.

[0071] FIG. 7 is an explanatory diagram of an insulating wall of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0072] The insulating wall (500) connects a pair of side plates (400) to each other. At this time, the insulating wall (500) is fixed at a point spaced inward by a predetermined distance from the ends of the pair of side plates (400). Through this, the side plates (400) protrude outside the insulating wall (500).

[0073] Meanwhile, the height of the insulating wall (500) is provided to be higher than the height of the side plate (400). Accordingly, when the emitter module (100) is attached to the lower surface of the insulating wall (500), the side plate (400) and the emitter module (100) are separated from each other. That is, the collector module (200) and the emitter module (100) are separated from each other.

[0074] The insulating wall (500) is made of an insulating material. As an example, it may be made of bakelite or epoxy glass.

[0075] The insulating wall (500) is provided to minimize surface discharge. Surface discharge may occur from the emitter module (100) to the metal side plate (400). Surface discharge may occur when the surface of the insulating wall (500) is contaminated or becomes wet. Accordingly, a groove may be formed in the insulating wall (500) that is recessed inward from one side. In this embodiment, the groove may alternately be formed as a first groove (510) and a second groove (520) that is recessed inward from the other side. By increasing the surface discharge distance through the first groove (510) and the second groove (520), surface discharge can be minimized. That is, in the drawing, when grooves such as the first groove (510) and the second groove (520) are not formed, the surface discharge distance becomes D1, but when the first groove (510) and the second groove (520) are formed, the surface discharge distance becomes D2, thereby increasing the surface discharge distance and minimizing the surface discharge.

[0076] The insulating wall (500) may be divided into a first area (530) in which grooves (510, 520) are formed and a second area (540) without grooves, wherein the width of the first area (530) is smaller than the width of the second area (540). Specifically, both ends of the first area (530) are located inwardly compared to both ends of the second area (540).

[0077] In a high-humidity environment, a discharge may occur between the insulating wall (500) and the housing (2000). This is due to insulation breakdown caused by high humidity. Accordingly, by making the width of the first region (530) smaller than the width of the second region (540), the distance between the end of the first region (530) and the housing (2000) is increased so that insulation breakdown does not occur.

[0078] Meanwhile, each corner formed in the insulating wall (500) can be rounded. Since discharge may occur at the corners in a high-humidity environment, the corners can be made curved to minimize water accumulation.

[0079] FIG. 8 is an explanatory diagram of a modified example of an insulating wall of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0080] As a variation, the insulating wall (500') may include an insulator (501) and a bracket (502) to which the insulator (501) is fixed.

[0081] A groove may be formed in the insulator (501) by being recessed inward from one side. In this embodiment, the groove may alternately be a first groove (510) and a second groove (520) by being recessed inward from the other side. As the surface discharge distance is increased by the first groove (510) and the second groove (520), surface discharge can be minimized, just as with the insulating wall (500) above.

[0082] The bracket (502) is fixed to the insulator (501), and the bracket (502) connects a pair of spaced-apart side plates to each other. The bracket (502) can be joined to the side plates by bending both ends. The width of the bracket (502) is provided to be greater than the width of the insulator (501). Accordingly, both ends of the insulator (501) are located inward from both ends of the bracket (502).

[0083] Accordingly, by making the width of the insulator (501) smaller than the width of the bracket (502), the distance between the end of the insulator (501) and the housing (2000) is increased so that insulation breakdown does not occur.

[0084] In the embodiment, the bracket (502) may be made of a metal material, and an insulating member may be placed between the insulator (501) and the bracket (502) for insulation. In the embodiment, the insulating member may be a PVC insulating film, but is not necessarily limited thereto.

[0085] The above-described electrostatic precipitator module (3000) is described in detail in the inventor's patent No. 10-2681365.

[0086] FIG. 9 is a perspective view of a vibration module of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention, and FIG. 10 is an exploded perspective view of a vibration module of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0087] The vibration module (4000) is mounted on the electrostatic precipitator module (3000) and is configured to apply vibration to the electrostatic precipitator module (3000) so that dust collected in the collector and dust attached to the emitter are detached.

[0088] The force F exerted by vibration on the mass m of the captured dust m It is as follows.

[0089]

[0090] Here, rpm is the rotational speed per minute of the vibration motor (4100), and r is the amplitude of the vibration.

[0091] At this time, the particle with mass m has an adhesive force F d It is attached to the electrode surface (emitter, collector) by means of. Therefore, F m >F d The particles are separated from the electrode surface.

[0092] Specifically, the force F that a particle receives due to vibration m When the particle undergoes simple harmonic motion, the displacement of the particle is is. (Here, r is the amplitude of the vibration, and ω is the angular velocity.)

[0093] And the speed is is, and acceleration is am.

[0094] Therefore, the force F acting on the dust m silver and therefore the maximum force is am.

[0095] At this time since am.

[0096] The vibration module (4000) includes a vibration motor (4100) and a vibration module bracket (4200). In this embodiment, the vibration module (4000) is provided as a pair and is fixed to each side of the electrostatic precipitator module (3000). The vibration motor (4100) includes a motor shaft (4110) and an eccentric mass (4120) fixed to the motor shaft (4110). The vibration motor (4100) is a known configuration.

[0097] The vibration module bracket (4200) is configured such that the vibration motor (4100) is fixed and the electrostatic precipitator module (3000) is mounted on the housing (2000). The vibration module bracket (4200) may include a first bracket (4210) fixed to the electrostatic precipitator module (3000) and a second bracket (4220) fixed to the vibration motor (4100), and the first bracket (4210) and the second bracket (4220) may be combined with each other.

[0098] At this time, the bracket, particularly the first bracket (4210), includes a mounting portion (4211) that is inserted into and mounted in the mounting hole (2040).

[0099] FIG. 11 is an explanatory diagram of the mounting structure of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0100] As described above, the electrostatic precipitator module (3000) is placed inside the housing (2000) but is not fixed to the housing (2000). This is to maximize the vibration application and cleaning efficiency by the vibration module (4000) (and the thrusting module (5000)).

[0101] A mounting hole (2040) is formed in the housing (2000), and a mounting portion (4211) is inserted into the housing (2000) and protrudes to be fixed. That is, the vibration module bracket (4200) is fixed to the electrostatic precipitator module (3000), and the electrostatic precipitator module (3000) is mounted to the housing (2000) by the mounting portion (4211) of the vibration module bracket (4200) being mounted in the mounting hole (2040), and is not fixed to the housing (2000).

[0102] At this time, the size of the mounting hole (2040) is formed to be larger than that of the mounting portion (4211). Specifically, the width and height of the mounting hole (2040) are provided to be larger than the width and thickness of the mounting portion (4211). Accordingly, the mounting portion (4211) is provided to be movable along the length / width / height direction of the mounting hole (2040). In other words, the mounting hole (2040) is provided to be larger than the mounting portion (4211), thereby allowing movement of the vibration module bracket (4200). In the embodiment, the width and height of the mounting hole (2040) may be about 2 to 3 mm larger than the width and thickness of the mounting portion (4211).

[0103] When the electrostatic precipitator module (3000) is firmly fixed inside the housing (2000), the vibration or shock applied from the vibration motor to the electrostatic precipitator module (3000) is significantly reduced, thereby reducing the particle detachment effect. In particular, when the housing (2000) is fixed to a wall, the detachment effect becomes even smaller.

[0104] This is because when the electrostatic precipitator module is in a fixed state, vibration energy is easily absorbed or dispersed by the fixed structure. Also, the above From F m is constant, but since mass m becomes very large, the acceleration corresponding This is the same as the effect of becoming very small.

[0105] Additionally, the vibration motor (4100) induces vibration by utilizing the asymmetric rotation of the mass, and if the electrostatic precipitator module (3000) has degrees of freedom, this vibrational motion can act more effectively on the electrostatic precipitator module (3000).

[0106] Additionally, due to the applied vibration, the mounting part (4211) vibrates freely while mounted in the mounting hole (2040), and during this process, an impact occurs due to the collision between the housing (2000) and the vibration module bracket (4200), which can increase the particle detachment effect.

[0107] FIG. 12 is an explanatory diagram of the fixing structure of a vibration module of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0108] The vibration module bracket (4200) is fixed to the side plate (400) and / or the insulating wall (500). In this embodiment, the side plate (400), the collector bracket (600), and the collector (210) are electrically connected to each other, and all are electrically grounded by grounding any one of them. Accordingly, the vibration module bracket (4200) is also electrically grounded.

[0109] The vibration module (4000) is operated when the electrostatic precipitator module (3000) is not in operation. That is, vibration is applied when high voltage is not applied to the electrostatic precipitator module (3000). When not in vibration (when the electrostatic precipitator module (3000) is on), the surface of the mounting part (4211) strongly presses against the surface of the mounting hole (2040) due to the weight of the electrostatic precipitator module (3000) to form an electrical connection, so both the collector (210) and the housing (2000) maintain a grounded state.

[0110] Meanwhile, the force F received by a particle with small mass m due to the aforementioned vibration m This becomes smaller. As particles become smaller, the ratio of surface area to volume increases. Therefore, small particles are relatively difficult to separate. This is because as the volume decreases, the force acting on the surface becomes greater than the force acting on the volume. Accordingly, it is desirable to apply vibration when particle capture has progressed to a certain extent and the mass m has increased.

[0111] FIG. 13 is an explanatory diagram of the arrangement of a vibration module of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0112] Meanwhile, in this embodiment, a blackening phenomenon may occur at the pin tip of the emitter (130). The blackening phenomenon is a phenomenon in which particles grow and harden at the end of the emitter (130) over time during corona discharge, causing a black ball (fuzz ball) to grow.

[0113] In this embodiment, the direction of the motor shaft (4110) of the vibration motor (4100) is arranged to intersect with the height direction of the emitter (130), and preferably to be orthogonal. Considering the direction of the centrifugal force acting on the center of gravity of the eccentric mass (4120) fixed to the motor shaft (4110), the force acts in the direction orthogonal to the motor shaft (4110), but the force is relatively small in the direction parallel to the motor shaft (4110), that is, the same direction. Therefore, in this embodiment, the direction of the motor shaft (4110) is arranged to be orthogonal to the height direction of the emitter so that particles with blackening phenomena can be effectively detached.

[0114] The direction of the motor shaft (4110) is arranged to be perpendicular to the height direction of the emitter, so that the direction of the centrifugal force acts in the height direction of the emitter. If the black ball (fuzz ball) is assumed to be a single rigid body, when it vibrates in a direction perpendicular to the height direction of the emitter, the rigid body may not be able to detach in one direction because the other direction is blocked, but when the vibration acts in a direction perpendicular to the height direction of the emitter, there is no such action, so the detachment of the rigid body by vibration is easy.

[0115] In other words, by arranging the direction of the motor shaft (4110) to be orthogonal to the height direction of the emitter, the vibration caused by the rotation of the eccentric mass (4120) acts in the height direction of the emitter, thereby allowing particles to be easily detached from the emitter.

[0116] FIG. 14 is an explanatory diagram of a thrusting module of an electrostatic precipitator having a cleaning structure according to an embodiment of the present invention.

[0117] The tapping module (5000) is configured to complement the vibration module (4000) to allow particles to be detached. The tapping module (5000) may include a bell unit and a fixed bracket.

[0118] The tapping module (5000) is positioned below the emitter module (100) and can be fixed to the housing (2000).

[0119] The alarm unit may include a motor and a piston, and the rotational motion of the motor shaft may be converted into the reciprocating motion of the piston. As the piston of the alarm unit moves back and forth, it strikes the emitter module (100), causing the emitter (130) and the collector (210) to vibrate, thereby causing particles to be detached.

[0120] As a variation, the alarm unit may include a solenoid, and when current is applied, the solenoid generates a magnetic field so that the piston moves, and when the current is cut off, the magnetic field disappears and the piston returns to its original position by a restoring force such as a spring so that the piston can reciprocate.

[0121] Insulation is required when particles are removed by the tapping module (5000). The alarm unit is fixed to the housing (2000) by a fixed bracket, and can be electrically grounded by the fixed bracket being coupled to the housing (2000).

[0122] Additionally, an insulating layer (5100) may be fixed to the lower surface of the emitter module (100), that is, the lower surface of the support frame (110). In this embodiment, the insulating layer (5100) may be formed of epoxy, and the piston of the alarm unit may strike the insulating layer (5100).

[0123] The insulating layer (5100) includes a first insulating layer fixed to the lower surface of the support frame (110) and a second insulating layer fixed to the first insulating layer, and through this structure, surface discharge can be prevented. In addition, the first insulating layer and the second insulating layer can be bonded to each other with an epoxy adhesive, and the first insulating layer and the support frame can be fixed by bolt connection or bonding with an epoxy adhesive.

[0124] As a variation, the insulating layer (5100) can be replaced with a concave container (5200) made of a synthetic resin such as plastic.

[0125] Meanwhile, the tapping module (5000) may be mounted on both sides (2020) of the housing (2000) and may vibrate the collector module (200) by applying impact to the vibration module bracket (4000). Through this, if the particle detachment effect through the vibration module (4000) is insufficient, the vibration module can be supplemented to allow the particles to be detached.

[0126] The collection unit (6000) is configured to collect particles that are detached from the electrostatic precipitator module (3000) and fall by the vibration module (4000) and the tapping module (5000).

[0127] The collection unit (6000) may include a collection container (6100) and a support member (6200).

[0128] The collection container (6100) has a container shape with an open top surface and is positioned below the housing (2000) and spaced apart from the housing (2000).

[0129] At this time, a second mounting hole (2050) is formed in the housing (2000), and a third mounting hole (6010) is formed in the collection part (6000). The support member (6200) has both ends bent and mounted in the second mounting hole (2050) and the third mounting hole (6010), respectively, so that the collection container (6100) is maintained in a state separated from the housing (2000). Furthermore, the separation of the collection container (6100) is easy through the mounting structure of the support member (6200).

[0130] Meanwhile, as a variation example, the support member (6200) can be fixed not only to the collection part (6000) and the housing (2000) but also to the collection part (6000).

[0131] Since the collection container (6100) is spaced apart from the lower part of the housing (2000), it does not affect the volume of ion wind generated in the electrostatic precipitator module (3000).

[0132] The collection container (6100) may be equipped with a scattering prevention unit (6300) to prevent the collected particles from scattering. The scattering prevention unit (6300) may be configured such that falling dust passes through a plurality of spaced-apart wing parts, while the collected dust is not scattered. At this time, the above effect can be more clearly achieved by each wing part forming a predetermined angle of inclination with respect to the height direction of the collection container (6100).

[0133] As a variation, the scattering prevention part (6300) may be a metal mesh having a grid structure. The metal mesh may be made of stainless steel.

[0134] The scattering prevention member (6300) may be optionally installed. The support member (6200) can be separated from the housing (2000) and the collection container (6100) by releasing the support member (6200), and the gap between the housing (2000) and the collection container (6100) can be adjusted by replacing the support member (6200). The gap between the housing (2000) and the collection container (6100) is preferably greater than the width of the electrostatic precipitator module (3000) so as not to affect the airflow of the ion wind generated in the electrostatic precipitator module (3000). If the gap between the housing (2000) and the collection container (6100) is large (for example, more than twice the width of the electrostatic precipitator module), there is no risk of the particles collected in the collection container (6100) being re-scattering by the ion wind, so the scattering prevention member (6300) may not be necessary.

[0135] As described above, according to the present invention, an electrostatic precipitator having a cleaning structure capable of efficiently and effectively removing particles, such as dust, collected in an electrostatic precipitator module is provided.
