DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

In the present specification, dust includes particles and sludge in the form of particles having a diameter of 0.1 to 500 mu m. Dust refers to a solid type material suspended or scattered in the air, and sludge means a solid type material having a relatively large diameter as compared to dust. The dust also includes microorganisms contained in the air, particulate matter generated in the combustion process, or contaminants harmful to the human body. As used herein, dust means all types of contaminants contained in the air, and each contaminant can be removed through an appropriate filter module or processing means. Therefore, the present invention is not limited by the kind of the pollutant.

The dust removing apparatus 10 according to the present invention can be applied to a place where various pollutants are required to be prevented, such as an industrial site, a public facility, or a semiconductor process, and can be operated independently or in conjunction with an air conditioner. Further, the dust removing apparatus 10 according to the present invention can be applied regardless of the particle size of the pollutant, and can be applied to the removal of fine dust including microorganisms according to a filter installed. Therefore, the dust removing apparatus 10 according to the present invention is not limited by the application equipment, the kind of the pollutant or the size of the fine dust.

1A and 1B show an embodiment of a dust removal device 10 according to the present invention.

Referring to FIGS. 1A and 1B, the dust removing apparatus 10 according to the present invention includes a rectifying chamber 11 for introducing outside air to form an air flow; An airflow distribution module (12) for distributing the airflow formed by the rectification chamber (11) while distributing them in different directions; An inertial dust collecting module (13) for modifying the flow of the air stream dispensed by the dispensing module (12) to remove sludge; A pressure regulating plate 14 for regulating the pressure of the airflow passing through the inertial dust collecting module 13; A multi-stage filter module for gradually removing dusts having different sizes from the air flow controlled by the pressure regulating plate 14; And a sludge collection unit (17) for collecting the sludge. The sludge collection unit (17) is connected to the airflow distribution module (12) so that the pressure of the airflow formed in the rectification chamber (11) And adjusts the pressure of the airflow or the internal pressure of the collection unit 17 according to the characteristics of the incoming airflow.

The contaminated air containing dust can be introduced into the rectification chamber 11 through the inlet conduit 111 and forced into the rectification chamber 11 through means such as a fan if necessary. The rectification chamber 11 may have a function to induce smooth air flow of the contaminated air flowing through the inflow conduit 111. The inside of the rectification chamber 11 may be formed to have a curved channel connected to the inlet conduit 111 or to have a high flow velocity at a portion where the channel is changed from the inlet conduit 111. The rectification chamber 11 may have a function of preventing the occurrence of turbulence or laminar flow due to the change of the position of the air flow and the sudden air induction path provided between the airflow distribution module 12. The rectification chamber 11 may have a box shape or a cylindrical shape and has a function of preventing inflow of air into the airflow distribution module 12 at a high speed. A linear airflow can be formed as the air containing contaminants flows from the inlet conduit 111 to the rectification chamber 11.

The induction conduit 112 may have a function to cause the contaminated air passing through the rectification chamber 11 to be led to the airflow distribution module 12 while forming a linear airflow. The induction conduit 112 may extend linearly and extend to the rectifying chamber 11 to an appropriate length depending on the curvilinear path and radius of curvature. For example, when the air flow path formed inside the rectification chamber 11 is long, the length of the induction conduit 112 becomes long, and thus a linear airflow can be easily formed.

Contaminant air, which is made into a linear air stream in the induction conduit 112, may be introduced into the airflow distribution module 12. The airflow distribution module 12 may have the function of making the linear airflow in the form of a dispersion air stream directed in different directions and making the pressure between the airflows induced along each direction equal. The airflow distribution module 12 may be in the form of a cone having a gradually increasing cross sectional area from the end of the induction conduit 112 and may include one guide unit 121 and one guide unit 121 for distributing air in different traveling directions, And two guide units 122 spaced apart from each other. 1 guiding unit 121 may include a plurality of grid-shaped guiding paths for distributing contaminated air in different directions. The two guide units 122 may be disposed separately from the one guide unit 121 while having a relatively short flow length as compared with the one guide unit 121. The first guide unit 121 and the second guide unit 122 may have a flow path whose cross-sectional area increases from the center outwardly, and gradually increase in cross-sectional area in the extending direction. The separation of the two guide units 122 is intended to compensate for the pressure difference between the distributing air streams flowing in different directions through the one guide unit 121. [ The sizes of the cross-sectional areas along the different directions in the one guide unit 121 and the two guide unit 122 can be set so as not to generate a pressure difference between the distributing airflows moved in different directions. As described above, the dispersing air stream radially dispersed through the airflow distribution module 12 and flowing at the same time with uniform pressure along different directions can be guided to the inertial dust collecting module 13.

The large diameter sludge or heavy dust can be removed from the inertial dust collecting module 13. The inertial dust collecting module 13 may have a plurality of parallel induction paths PP formed in parallel with each other and having a function of removing dust or sludge by weight. The parallel guiding path PP forms a linear path but the flow of a part of the airflow can be changed by the path changing guide 131 forming the parallel guiding path PP so that the sludge can be dropped and removed. And the dropped sludge can be collected by the sludge collection unit 17. The parallel guide path PP may be formed to extend in a straight line while being connected to a distribution air flow path formed in the air flow distribution module 12, but it is not limited thereto and various structures may be made to remove the sludge in the course of air flow . The air passing through the inertial dust collecting module 13 may be guided to the pressure regulating plate 14 in order to compensate for the pressure difference caused by the flow path change of a part of the air flow in the process of removing the sludge.

The pressure regulating plate 14 has a function of making the pressure of the air flow uniformly along the moving direction while decreasing the flow speed of air before the air is introduced into the multi-stage filter module MC for removing fine dust from the air stream from which the sludge has been removed. . The pressure regulating plate 14 may have a plate shape having a plurality of through holes having different diameters. The air flow whose flow rate and pressure are controlled by the pressure regulating plate 14 can be gradually purified while passing through the multi-stage filter module MC.

The multi-stage filter module MC may have a chamber structure in which a plurality of filter units 15 and 16 are disposed, and the pressure regulating plate 14 may have an inlet function in the multi-stage filter module MC. The multi-stage filter module (MC) may be provided with filter units (15, 16) or sterilizing means having various functions. Specifically, the primary filter unit 15 can be disposed apart from the pressure regulating plate 14 by a predetermined distance. And the secondary filter unit 16 may be disposed at a position spaced apart from the primary filter unit 15. The primary filter unit 15 can be a multi-layer filter structure and can remove dust having a diameter of, for example, 3 to 15 mu m in size. As shown in FIG. 1B, the multi-layer filter structure refers to a structure in which a plurality of filter layers 151 are arranged along a height at regular intervals. In the multilayer filter structure, each of the gradient filter layers 151 may be disposed at an inclination with respect to the flow direction of the airflow. And a cleaning unit 152 having a plurality of nozzles may be disposed above each filter layer 151 as required. The inclined filter layer 151 allows the dust contained in the airflow to be easily separated from the airflow while blocking the filter pores due to dust. The cleaning unit 152 may be operated in accordance with the reduction of the filtration performance of the filter layer 151, and the cleaning may be performed by a fluid mixed with air and water. Supply conduits 153 and 154 for supplying air and water to the cleaning unit 152 may be provided and the fluid used for cleaning the respective filter layers 151 may be dropped downward and discharged to the outside. A drying unit may be provided with the cleaning unit 151, and the drying unit may be, for example, a near-infrared lamp or other suitable heater unit. Each of the filter layers 151 may be composed of at least one filter, and the present invention is not limited by the filter type. The airflow passing through the primary filter unit 15 can be led to the secondary filter unit 16.

The secondary filter unit 16 may be made of a filter capable of removing dust having a relatively small diameter as compared with the primary filter unit 15. The secondary filter unit 16 may be a V-bank structure in which a plurality of V-banks are connected to each other. Each V-bank can be adjusted in the angle of inflow of the airflow, and each V-bank can be coupled to each other to be detachable. Such a V-bank structure has an advantage in that the angle of flow can be appropriately controlled according to the velocity of the airflow while allowing the airflow to flow in and out of the inclined direction. At least one filter layer may be formed in each V-bank.

The airflow in which the fine dust is finally removed by the secondary filter unit 16 can be discharged to the outside of the multi-stage filter module MC. The sterilizing unit 18 may be disposed on the discharge surface of the multi-stage filter module MC or outside the multi-stage filter module MC. The sterilization unit 18 may have various sterilization structures such as ultraviolet sterilization, ultrasonic sterilization or ozone sterilization. The purified air stream sterilized by the sterilization unit 18 can then be discharged through the outlet 191 formed in the discharge module 19 in the direction indicated by the arrow CA to the outside.

As described above, the characteristics of the air flow formed in the contaminated air flowing from the outside and purified in the dust removing apparatus 10 according to the present invention may greatly affect the dust collecting efficiency. For example, the pressure of the airflow entering through the induction conduit 112 may be gradually reduced while passing through the airflow distribution module 12, the inertial dust collection module 13, and the pressure regulating plate 14, Levels need to be adjusted appropriately. In addition, the characteristics or the pressure of the air flow need to be appropriately adjusted according to the temperature state inside the dust removing apparatus 10. [ Such as a forced pressurizing means such as a fan or a temperature regulating means, may be provided to regulate the characteristics of the air flow. Various air flow characteristic adjusting means may be installed in the dust removing apparatus 10. [

According to the present invention, a sludge collection unit 17 may be connected to the rectification chamber 11, the induction conduit 112, or the airflow distribution module 12 so as to allow air flow to control such air flow characteristics. Specifically, the inside of the sludge collecting unit 17 can be maintained at atmospheric pressure or a predetermined atmospheric pressure, and the sludge collecting unit 17 (or the sludge collecting unit) Air can be introduced. Such a pressure control of the airflow means a relative pressure control. Specifically, since the sludge collecting unit 17 is connected to the inertial dust collecting module 13, the pressure of the polluted air stream flowing through the induction pipe 112 according to the pressure difference between the inertial dust collecting module 13 and the induction pipe 112 So that the pressure of the airflow flowing into the inertial dust collecting module 13 is controlled.

The pressure control conduit 171 may be provided with a pressure control conduit 171 for connecting the sludge collection unit 17 and the induction conduit 112, the rectification chamber 11, or the airflow distribution module 12, A possible control valve 173 may be provided. And the air flow is caused to flow in accordance with the pressure difference between the induction conduit 112, the rectification chamber 11 or the airflow distribution module 12 and the sludge collection unit 17 so that the characteristics of the airflow entering the inertial dust collection module 13 Can be adjusted. A check box CB can be provided separately from the sludge collecting unit 17, and the control valve 173 can be made to be automatically opened and closed according to a preset pressure. In such a pressure regulating process, for example, a tube having a structure similar to a Bernoulli tube may be disposed in the induction conduit 112.

The airflow characteristics in the dust removal apparatus 10 according to the present invention can be adjusted in various ways, and the present invention is not limited to the embodiments shown.

2 shows an embodiment of an inertial dust collecting module 13 which can be applied to a dust removing apparatus according to the present invention.

2, the inertial dust collecting module 13 may be made of a louver blade structure, and a plurality of blades 131a may be successively arranged at intervals of, for example, 3 to 10 mm, A plurality of parallel guide paths PP can be formed by the path changing guides 131 facing each other. A sludge box 231 for collecting the sludge may be formed at the end of the parallel guide path PP. The sludge collected by the sludge box 231 can be collected in the collection unit 17 described above. Each of the blades 131a may have a convex lens or a crescent shape convex in the direction of flow of the airflow, and the flow path of a part of the airflow can be changed by the gap formed between the continuously arranged blades 131a. Each parallel guide path PP can be formed so that the width gradually decreases along the advancing direction of the airflow. A sealing plate 232 having an air shield function along the parallel guide path PP and fixing the blade 131a to a predetermined position may be disposed and a coupling member 233 for coupling the different sealing plates 232, Can be disposed.

The inertial dust collecting module 13 may be made of aluminum or stainless steel, for example, and may function as a filter for sludge of a finger thickness. The inertial force generated between the airflow and the sludge by the airflow resistance along the part of the airflow flowing between the continuous blades 131a of the sludge having the diameter or length in the range of 0.5-10 cm contained in the airflow by the inertial dust collecting module 13 The sludge can be collected. Other functions of the inertial dust collecting module 13 are such that the distributor air streams directed in different directions by the air stream distributing module 12 proceed parallel to each other. Thus, fine dust can be efficiently removed from the air stream in which the sludge is removed in the multi-stage filter module.

The inertial dust collecting module 13 can be made in various structures, and the present invention is not limited to the embodiments shown.

3 shows an embodiment of a pressure regulating plate 14 which can be applied to the dust removing apparatus according to the present invention.

Referring to FIG. 3, the pressure regulating plate 14 may include a plurality of regulated porous plates 343 fixed by fixing members 341 and 342. The pressure regulating plate 14 may be disposed in front of the multi-stage filter module to prevent contamination or breakage of the filter unit, and to adjust the speed or pressure of the airflow entering the filter. The pressure regulating plate 14 is composed of a plurality of regulated porous plates 343 so that uniform pressure is formed in the direction of the airflow by regulating pressure in each region. A plurality of through holes may be formed in each of the adjusting porous plates 343, and the through holes may have different diameters depending on positions. For example, the through holes may be arranged such that the diameter increases from the central portion of the pressure regulating plate 14 toward the outside. Or vice versa. The diameter of the through hole of the adjustment porous plate 343 can be appropriately determined according to the distance between the pressure regulating plate 14 and the multi-stage filter module or the area of the facing surface. The pressure of the pressure regulating plate 14 can be adjusted so that the induced airflow having a uniform pressure in the horizontal direction can be guided to the multi-stage filter module.

4A shows an embodiment of a primary filter unit 15 that can be applied to a dust removal device according to the present invention.

Referring to FIG. 4A, the primary filter unit 15 may be composed of a plurality of gradient filter layers 151, and each gradient filter layer 151 may include a plurality of filter layers. And a cleaning unit 152 for cleaning each of the gradient filter layers 151 may be disposed above the gradient filter layer 151. [ The inclined filter layer 151 has a function of removing a large amount of fine dust from the airflow passing through the inertial dust collecting module and the collecting performance of the inclined filter layer 151 can be maintained by the washing unit 152. The cleaning unit 152 may be arranged to be movable along a guide member 451 by a drive unit 452 such as a motor. The cleaning unit 152 may be composed of a plurality of spray nozzles and the plurality of spray nozzles may be arranged such that one direction of the gradient filter layer 151 can be completely washed. And the entire inclined filter layer 151 can be cleaned while the cleaning unit 152 is moved in the other direction of the inclined filter bed 151 by the drive unit 452. [ And, as described above, the cleaning can be done, for example, by a mixed fluid of air and water, and various additives can be added as needed. The drying unit may be installed together with the cleaning unit 152, and the drying unit may be formed by various methods such as a heater, a near infrared ray lamp, or air drying. The cleaning unit 152 may have a plurality of nozzles and the cleaning liquid used for cleaning should be able to be collected by a collection means that does not disturb airflow.

According to the present invention, a cleaning liquid collection unit 453 connecting the different ends of the gradient filter layers 151 adjoining each other up and down can be disposed between adjacent gradient filter layers 151. [ The cleaning liquid collecting unit 453 can be formed in a structure having a curved shape as a whole and a structure in which the cleaning liquid flows naturally and collects. Each of the cleaning liquid collection units 453 may be connected by an appropriate connection conduit and collected in the lower tank and discharged to the outside. The washing liquid collecting unit 453 can form an airflow guiding curved surface that induces an airflow between adjacent inclined filter layers 151. [ Specifically, the airflow introduced into the gradient filter layer 151 needs to be guided in the form of a stream passing through the filter layer formed in the gradient filter layer 151. For this purpose, the washing liquid collecting unit 453 may form an airflow guiding curved surface connecting one end of the vertically adjacent gradient filter layer 151 and the other end. The airflow guiding curved surface may be formed into a curved shape that leads the airflow to the filter layer 151 while gradually becoming narrower from the inlet where the airflow is introduced.

The cleaning unit 152 can be made in various structures and the present invention is not limited to the embodiments shown. The cleaning liquid is scattered in the cleaning process of the inclined filter layer 151 by the cleaning unit 152 so that the contaminants stacked on the inclined filter layer 151 can be scattered together, So that the performance of the entire dust removing device including the inclined filter layer 151 may be deteriorated. Such a problem due to scattering can be similarly generated in the cleaning process of the secondary filter unit. Therefore, an appropriate means for preventing scattering generated in the cleaning process of the filter unit is required.

FIG. 4B shows an embodiment of a filter cleaning unit capable of being applied to the dust removal apparatus according to the present invention. FIG.

Referring to FIG. 4B, a plurality of nozzles N may be installed on the movable cleaning unit 152 disposed above the gradient filter layer 151, The range SR can be determined. The injection range SR can be determined by the number of nozzles or the arrangement structure and can be set so as not to overlap with each other in the gradient filter layer 151. [ The scattering prevention units 154a, 154b, 155a, and 155b may be formed in a shape that covers the cleaning unit 152 from above or a surrounding shape. Specifically, the scattering prevention units 154a, 154b, 155a and 155b may be formed so as to separate the cleaning unit 152 from each other. The upper side of the inclined filter layer 151 may be sealed by a cover for installing the cleaning unit 152. [ Therefore, the scattering prevention units 154a, 154b, 155a, and 155b are formed along the circumference of the cleaning unit 152 and include one scattering prevention walls 154a and 154b for preventing scattering in one direction, And two scattering prevention walls 155a and 155b that prevent scattering in two directions perpendicular to one direction. The scattering prevention units 154a, 154b, 155a and 155b may be constructed to be inserted into and fixed to the inside of the main cover forming the outer cover, and may be made detachable from the main cover. A droplet prevention plate 157, such as a demister, is disposed between the one shroud prevention walls 154a and 154b and the two shroud prevention walls 155a and 155b to remove the floating moisture during the cleaning process. The droplet prevention plate 157 may be disposed so as to be spaced apart from the inclined filter layer 151, and may be formed to be separated into a lower space and an upper space.

The scattering prevention units 154a to 155b may be formed in various structures in which a closed space in which the gradient filter layer 151 and the nozzles N of the cleaning unit 152 are arranged vertically is formed, .

5 shows an embodiment of a secondary filter unit 16 which can be applied to a dust removal device according to the present invention.

5, the secondary filter unit 16 can be made in a V-bank structure, and a plurality of plate-shaped inlet angle-adjusting filters 161 are connected to each other by an inlet angle-adjusting bracket 561, And can be made to be V-shaped. The secondary filter unit 16 causes the inlet airflow to flow into the filter at an angle other than the vertical angle by the inlet angle control filter 161 so that the effect of expanding the filtration area substantially occurs. Each inlet angle-adjusting filter 161 may be arranged to be detachable, and may be formed of a plurality of filter layers. The inflow angle control filter 161 adjacent to each other can adjust the inflow angle of the airflow by the inflow angle control bracket 561.

The secondary filter unit 16 having various structures can be applied to the dust removing apparatus according to the present invention and the present invention is not limited to the embodiments shown.

Fig. 6 shows an embodiment of the collection unit 17 according to the present invention.

As described above, the collection unit 17 may be installed under the inertial dust collection module to collect sludge. The collection unit 17 may have a function of adjusting the characteristics of the airflow introduced into the dust removing apparatus or the airflow pressure. Or the internal pressure of the collection unit 17 can be adjusted.

The collection unit 17 includes a collecting body 671 for collecting sludge SL on the bottom surface thereof, a pressure control conduit 171 connected to the induction conduit, a sludge inlet for introducing the sludge SL collected from the inertial dust collecting module, And at least one guide plate 673a, 673b, 673c for guiding the air flow inside the collecting unit 17 and the collecting unit 672. The pressure control conduit 171 may be connected at one end to the collection unit 17 by a connector 171a and at the other end to an induction conduit. It is advantageous that the pressure inside the collection unit 17 is lower than the internal pressure of the inertial dust collection module in order to induce the fall of the sludge SL. Since the sludge SL is accumulated in the bottom of the collection unit 17 and the air introduced together with the sludge contains fine dust, it needs to be filtered. Air introduced with the sludge SL through the inlet can be led to the pressure control conduit 171 by guide plates 673a, 673b, 673c. The guide plates 673a, 673b and 673c may be disposed on the ceiling surface or the side surface of the collection unit 17 so as to be parallel or inclined with respect to the bottom surface since the suspension of the sludge SL should be prevented in this process . Also, the pressure inside the collection unit 17 can be made equal to or lower than the internal pressure of the inertial dust collection module, and can be adjusted to be, for example, 70 to 95% of the internal pressure of the inertial dust collection module. Another function of the guide plates 673a, 673b and 673c is to make the upper surface of the sludge SL accumulated on the bottom surface of the collection unit 17 flat. Generally, sludge SL is introduced through sludge inlet 672 and sludge SL is pushed to the opposite side of sludge inlet 672 when the internal air of collection unit 17 is discharged through pressure control conduit 171 As a result, the sludge SL is accumulated in a convex mountain shape. This may cause floating of branches. Therefore, in order to prevent this, the guide plates 673a, 673b, and 673c may guide the air introduced into the sludge inlet 172 to the side without being directed toward the bottom surface.

The other end of the pressure control conduit 171 may protrude into the induction conduit and the pressure inside the induction conduit may be low due to the Bernoulli principle due to the flow of air through the conduit. As a result, the air inside the collection unit 17 naturally flows into the interior of the induction conduit. If too much air is introduced into the induction conduit in this process, the formation of the total airflow may be hindered. For example, the amount of air flowing into the internal conduit from the collection unit 17 can be adjusted to be 5 to 15% of the total amount of air. A control valve may be provided in the pressure control conduit 171 for this purpose. A screen mesh 68 may also be provided to prevent the entry of dust into the pressure control conduit 171. The mesh specification of the screen mesh 68 may be suitably set according to the size of the branch collected in the collection unit 17 and the size of the fine particles allowed to flow into the airflow distribution module.

The sludge collected in the collection unit 17 can be discharged through the check box CB.

With this structure, the dust contained in the sludge SL can be filtered while allowing the sludge SL to be completely collected in the dust removing apparatus according to the present invention, . The collection unit 17 and the induction conduit can be connected to allow air flow in various ways, and the present invention is not limited to the embodiments shown.

The dust removing device according to the present invention effectively removes dust or contaminants having different sizes by a continuously installed filter module by controlling the pressure of inflowing polluted air. The angle of inflow and outflow of the airflow according to the present invention can be adjusted, and a replaceable filter module is applied to facilitate maintenance and management of the cleaning device. By effectively dispersing the incoming air according to the present invention, different kinds of dust or contaminants can be completely removed at each stage. In addition, the dust removal device according to the present invention can be used in various environments by applying a replaceable filter module.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention . The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
