Description

A conductive filter module, a conductive filter module including a conductive filter unit, and a fine dust removal system with a conductive filter module

The present invention relates to a fine dust removing system provided with a conductive filter module, and more particularly, to a fine dust removing efficiency with a low pressure loss by providing a conductive filter module including a cylindrical conductive filter, And more particularly to a fine dust removing system provided with a conductive filter module having excellent applicability and versatility as an installation air cleaning device or an independent air cleaning device in the room.

Fine dusts are small in size and penetrate deep into alveoli without being caught by mouth or nasal airway during respiration of human body. They also have optical characteristics such as refraction and scattering of light, which causes many obstacles to securing sight. In addition, fine dusts contain many organic and harmful substances, and the fine dust that has penetrated into the lungs remains in the lungs. It transfers various harmful substances of organic and inorganic substances contained in the lungs to the human body to treat very serious respiratory diseases such as pneumonia, lung cancer and bronchitis ≪ / RTI >

Fine dust is not only a mobile pollutant source such as automobiles in our country but also a fixed pollution source caused by household heating and industrial energy consumption, as well as a yellow dust coming from the Gobi desert in China, and a large industrialization in recent years, And it is experiencing many difficulties due to fine dust in indoor as well as indoor.

Most of the air filtration apparatuses for removing fine dust in the room are using a method using a filter. Among the filters used to remove fine dust, the HEPA filter shows a high fine dust filtration rate capable of collecting 99.97% of fine dust having a diameter of 0.3 μm.

However, the HEPA filter is very effective in removing fine dust, but the nano-sized fine polymer or glass fiber is very densely entangled, and the filter permeation efficiency of air is very low. That is, the pressure loss is very large. Therefore, when the HEPA filter is used in an air cleaning system for removing fine dust, a large-capacity blower is required, and the power consumption due to the HEPA filter is large. Therefore, there is a disadvantage in additionally requiring facilities for noise and vibration. Also, since the once used HEPA filter can not be reused, there is a need to replace it every 6 to 12 months.

Recently, a variety of functional filter materials have been introduced to overcome the disadvantages of such a HEPA filter. A representative filter material is an electret filter which has a positive or negative charge on the filter material itself and effectively collects fine dust in the air through electrostatic force. However, the electric charge characteristics of the electrostatic filter disappear as the dust collects and accumulates, and the electric charge characteristic easily disappears even if it is stored for a long time without being used for capturing particulate pollutants. Even when the surface of the electrostatic filter is exposed to water or alcohol, the charging characteristics are very easily removed and the ability to remove fine dust is significantly lowered.

In order to solve the problem that the charge characteristics of the electrostatic filter easily disappear or deteriorate naturally or with external damage over time, the conductive filter is superimposed on the upper and lower sides of the filter having the dielectric property, The air filtering filter is electrostatically activated by applying a positive high voltage to the dielectric filter to electrically filter the dielectric filter (Japanese Patent Laid-Open No. 10-2011-0128465). However, there is still a problem of the high cost of the filter due to the complexity of the process and the need to make the filter three layers in total.

A method has been disclosed in which a metal is coated on a general nonwoven filter having a pressure loss of 1/5 to 1/20 of that of a general HEPA filter, and a conductive filter is applied to an electrostatic dust collecting system to very effectively remove fine dust (ACS Appl. Materials, Interfaces 2017, 9, 16495-16504). In order to solve the high pressure loss problem of the HEPA filter, a method of coating a metal with a filter material having a low pressure loss to maximize the electric field with the charged fine particles by giving a high electric conductivity, / 10 level, but fine dust could be removed at the same level as the HEPA filter.

However, when a filter bending method, which is generally applied to remove a large amount of air in a certain volume of space, is applied to a metal-coated conductive filter, a uniform electric field is not formed, and thus, The fine attraction of the fine dust is hardly achieved. That is, in order to purify a large amount of air containing fine dust by using a conductive filter material capable of maintaining a low pressure loss, a new filter module should be provided instead of the conventional filter bending method.

On the other hand, since there is little ion generation between the conductive filter inside the cylindrical module and the electrode, ions generated from the particleizer at the front end must exist up to the inside of the cylindrical module, so that fine dust removal efficiency can be improved. However, the movement of ions generated from the particle charging device is so fast that it is very likely to disappear by touching an object in the vicinity, so there are not many ions flowing into the cylindrical module. That is, since only the particles charged by the ions generated in the particle charging device can be removed from the conductive filter module, the uncharged fine dust between the particle charging device and the conductive filter module is not removed by the cylindrical conductive filter module May occur.

The present inventors have made intensive researches in order to overcome the problems of the prior art. As a result, in the case of a fine dust removing system including a conductive filter unit having an electrode rod including a cylindrical bending filter module and a conductive member having a carbon member disposed therein , The pressure loss is about 0.5 to 10 pa when the filtration speed of the air passing through the unfolded filter module is 5 cm / sec, which is about 1/20 to 1/5 of the pressure loss of the general hepa filter, By generating a strong electric field and a large amount of ions between the charging device and the conductive filter, it is possible to charge even the uncharged fine dust between the particle charging device and the conductive filter module, thereby purifying a large amount of air including fine dust with high efficiency And the present invention was completed.

Hereinafter, a conductive filter module 100 and a fine dust removing system 10 including the conductive filter module 100 according to an embodiment of the present invention will be described.

First, the conductive filter unit 110 of the present invention will be described.

1 and 2 show a conductive filter unit 110 constituting a conductive filter module 100 for collecting fine dust particles according to an embodiment of the present invention.

A conductive filter unit according to an embodiment of the present invention includes: a first electrode cap; A second electrode cap; A conductive filter forming an internal space between the first electrode cap and the second electrode cap and electrically connected to the first electrode cap; And an electrode connected to the second electrode cap and forming an electric field in an inner space formed by the conductive filter; .

In the present invention, as shown in FIGS. 1 and 2, the present invention includes a conductive filter unit 110 for high-efficiency dust collection using a conductive filter used for fine dust removal through a filtration system and an electrostatic dust collection system.

In order to highly efficiently collect fine dust through the conductive filter material, the conductive filter must be positioned in a relatively large area in a limited space, and a bent filter is generally used to install a filter having a larger area. The filter 111 can be made of any material having a filter structure made of an electrically conductive material.

For reference, the filter structure means an object having a structure composed of suitable pores and supports, a structure in which a fluid including particulate matter passes through the filter, a part or whole of particulate matter is adhered to and removed from the support, do.

Preferably, in order to satisfy the flexibility required for deformation such as bending and bending of the conductive filter, it is preferable that the filter is made of polymer, natural fiber, glass fiber, paper or the like rather than a bulk metal filter, It is preferable that the material is supplied in a coated state.

In order to collect fine dust efficiently through the conductive filter material, the area of the electrode made of the highly conductive material contacting the filter so that a uniform voltage is applied to the entire area of the conductive filter rather than a voltage applied to one side of the conductive filter .

In the present invention, the conductive filter 111 may be wound in a cylindrical shape with a predetermined diameter to include a conductive filter unit 110 capable of realizing a relatively narrow volume and a wide filtering area.

More specifically, the conductive filter unit 110 includes a first electrode cap 112; A second electrode cap 113; A plurality of supports (114) connecting the first electrode cap and the second electrode cap; A conductive filter (111) which surrounds the outer circumferential surface of the support and connects the first electrode cap and the second electrode cap while forming a space therein; And an electrode rod (115) protruding from the center of the second electrode cap to an inner space formed by the conductive filter.

The conductive filter unit 110 may have an opening formed in one side of the conductive filter 111 so as to allow air containing fine dust to flow between the conductive filter 111 and the electrode rod 115 A first electrode cap 112 having a ring shape and a second electrode cap 113 having an electrode rod on the other side and sealed to prevent air from entering.

In addition, it is preferable that an electrode made of a conductive material is provided on the first electrode cap 112 so that a high voltage can be applied to the conductive filter 111, or the first electrode cap 112 itself is made of a conductive material. The conductive filter 111 is rolled up so as to be in close contact with the first electrode cap 112 so as to be in contact with the electrode of the first electrode cap 112. The conductive filter 111 and the first electrode cap 112 are made of an adhesive material, So that the high-voltage application can be completed perfectly. At this time, the air introduced into the conductive filter 111 is prevented from escaping between the first electrode cap 112 and the conductive filter 111.

The second electrode cap 113 hermetically seals the lower portion of the conductive filter 111 and fixes the electrode 115. The second electrode cap 113 closely contacts the lower portion of the conductive filter 111. The lower part of the conductive filter 111 is completely tightly wound along the second electrode cap 113 and the air is discharged between the second electrode cap 113 and the conductive filter 111 as in the case of the first electrode cap 112. [ It is sealed and bonded with an adhesive material.

According to an embodiment of the present invention, since the lower portion of the conductive filter 111 is sealed by the second electrode cap 113, the second electrode cap 113 serves to fix the electrode rod 115 can do. The second electrode cap 113 is electrically connected to the conductive filter 111 and the electrode rod 115 in order to form an electric field between the conductive filter 111 and the electrode rod 115. In this case, It may be made of a short-circuited structure.

The conductive filter unit 110 according to the present invention includes a support 114 for connecting the first electrode cap 112 and the second electrode cap 113 and holding the conductive filter, Of the conductive filter 111 may be included.

In the high-efficiency dust collecting using the conductive filter 111 according to the present invention, it is necessary to allow all the air entering the fine dust removing system 10 to pass through the filter. For this purpose, a filter and a support The air introduced into the filter can pass through the filter without any external leakage. Thus, the conductive filter 111 wrapped around the support body 114 can be completely bonded with an adhesive material so as to prevent air from leaking between the both end portions of the filter.

The conductive filter unit 110 is disposed inside the conductive filter 111 by locating the electrode rod 115 protruding from the center of the second electrode cap 113 into the inner space of the conductive filter 111 wound in a cylindrical shape. So that a uniform electric field is formed between the electrode rod 115 and the inner surface of the filter.

The electric field between the conductive filter 111 and the electrode rod 115 plays a key role in allowing the fine dust introduced into the conductive filter 111 to be collected at high efficiency by the electric field by the electric field.

In order to form a uniform electric field between the conductive filter 111 and the electrode rod 115, an electrode must be formed on the first electrode cap 112 so that a high voltage can be applied to the conductive filter 111, The electrode 115 protruding from the inner space must have an electrode for applying a voltage of a polarity opposite to the voltage applied to the filter or for grounding the electrode.

Next, the electrode rod 115 of the present invention will be described.

3 and 4, the electrode rod 115 includes a conductive member 115a protruding from the second electrode cap to an inner space formed by the conductive filter 111, and a conductive member 115a And a carbon member 115b disposed on at least a part of the surface.

The carbon member 115b disposed on a part of the surface of the conductive member 115a may be carbon fiber and powdered carbon fiber for generating a large amount of ions between the particle charging device and the conductive filter, The length of the carbon fiber in the longitudinal direction may be 1 mm (millimeter) to 300 cm (centimeter), and the average particle diameter of the powdered carbon fiber may be 1um (micrometer) to 1000um (micrometer).

In the case of the conductive filter unit using the electrode rod 115 in which the carbon member 115b is disposed on the surface of the conductive member 115a, a high voltage of the same polarity as the high voltage applied to the particle lower portion is applied to the conductive member 115a The conductive filter applies a voltage of a polarity opposite to that of the high voltage applied to the ground or conductive member 115a.

A negative or positive high voltage is applied to the electrode 115 on which the carbon member 115b is disposed on the surface of the conductive member 115a and the ground or conductive member 115a is connected to the conductive filter And applies a high voltage having a polarity opposite to that of the applied high voltage.

In the case of the conductive filter unit using the conductive member 115a in which the carbon member 115b is disposed on the surface as the electrode rod 115, in addition to forming an electric field for inducing the charged particles to be collected in the conductive filter well, And induces ion generation to improve the chargeability of the fine dust particles. Particularly, in this case, the ions generated between the conductive member 115a and the conductive filter, that is, the conductive particles, are generated in the conductive member and move to the conductive filter. The fine dust particles moving in a direction perpendicular to this path collide with the ions The probability is increased and the particle charge rate can be dramatically improved. Also, due to collision with ions, the moving direction of the fine dust particles is changed to the direction of the conductive filter, and the collection efficiency by the electrostatic force can be greatly improved.

According to an embodiment of the present invention, when a cylindrical filter module including an electrode rod on which a carbon member is not disposed on a surface without a separate particle charging device is used to ground the conductive filter without applying voltage to the electrode rod, The average removal rate was 6.7%. On the other hand, a carbon member cut to a length of 0.5 cm (centimeter) to 7 cm (centimeter), a carbon member cut to a length of 1 mm (millimeter) to 3 mm (millimeter), and a carbon member cut to a length of 10um ) Was applied to an electrode rod in a cylindrical filter module including a powdered carbon electrode having a particle size of 1 to 6 kV and a conductive filter was grounded, the respective fine dust removal efficiencies were measured , The fine dust removing efficiency was 90 to 100% and excellent fine dust removal efficiency was exhibited.

Next, the conductive filter module 100 of the present invention will be described.

The conductive filter module 100 may include a filter fixing plate 120 for mounting and fixing a plurality of the conductive filter units 110 described above, as shown in FIGS. 5 to 6.

The filter fixing plate 120 may include an air inlet 121 as many as the number of the conductive filter units 110 to be connected to mount the conductive filter unit 110.

The air inlet 121 is formed to have a structure in which the first electrode cap 112 of the conductive filter unit 110 can be connected to the air inlet 121. The conductive filter 111 and the first The electrode cap 112 and the filter fixing plate 120 may not be electrically short-circuited.

7 and 10 illustrate a method in which a high voltage is applied to the conductive filter module 100 including the filter fixing plate 120 equipped with the plurality of conductive filter units 110 according to an embodiment of the present invention. Respectively.

In the present invention, a high voltage of 1 to 20 [kV] is applied to the conductive filter module 100 in order to form an electric field necessary for fine dust removal. The filter fixing plate 120, the first electrode cap 112, and the conductive filter 111 are connected to each other so that a high voltage is applied to the conductive filter 111 in a structure that is not electrically short-circuited. The electrode rod 115 is grounded or a high voltage of a polarity opposite to the voltage applied to the filter fixing plate 120 is applied to form a uniform electric field between the conductive filter 111 and the electrode rod 115.

When the electrode 115 having the carbon member 115b disposed on the surface of the electrode member 115a is used, the conductive filter 111 is grounded or a high voltage of a polarity opposite to the voltage applied to the electrode 115 is applied So that a large amount of ions can be generated from the electrode member 115a, and at the same time, the electric field between the conductive filter and the electrode rod is also enhanced, thereby maximizing the collection ratio of the fine dust particles on the conductive filter.

9 and 14 illustrate a mechanism for collecting fine dust when fine dust is introduced into the conductive filter unit 110 according to an embodiment of the present invention.
