It is a demister filled media electrostatic filter which is excellent in workability and productivity because the life of the product is maintained by the excellent durability even if it is washed and reused after being washed.

In general, the air conditioning system seeks to revive the trend of building facilities to be more advanced and advanced as the buildings become more advanced due to the high economic growth and the improvement of the residential culture. Air Quality (Law) is regulated by law, and on the basis of this, there is a continuous research to promote better indoor environment.

However, these buildings adopt a sealed structure to save energy, thereby reducing the indoor air pollution due to the lack of natural ventilation and the reduction of outdoor air intake.

To this end, recently, various air conditioning systems are encouraged to purify the internal air of the above-described buildings, which are installed in public facilities such as tunnels, subways, factories, department stores, hospitals, and medium and large buildings, and have a pleasant living environment or a clean interior. It is formed to purify the outside air introduced for the air.

On the other hand, the outside air introduced into the room contains a large amount of oil dust, contaminated water, dust, etc., such fine contaminants are filtered and collected by the dust removal filter before passing through the room, in particular, the performance of the filter Therefore, the above-mentioned fine contaminants are smoothly filtered.

Therefore, in the related art, one or more mesh nets are formed in the frame frame to filter out the contaminants of the outside air, and installed on one side of the ventilation system to filter and collect dust, fine dust, etc. introduced from the outside. Forming.

However, such a conventional filter is formed by forming a mesh network by simply weaving a plurality of wire rods formed of a metal material vertically and horizontally, or by using a nonwoven fabric to secure a collection amount and to reduce a cost cost. In case of mesh network, it is difficult to effectively filter fine contaminants such as dust (the pores that can be collected are large or have a large gap), and in particular, filtration is concentrated only on one side of the mesh network into which dust is introduced. As a result, the dust collection rate is biased or low.

Such a conventional filter has a short exchange and washing cycle, which lowers productivity. In particular, in the case of a nonwoven fabric, it is difficult to smoothly filter and collect dust, such as poor durability due to frequent durability due to contamination.

In addition, to compensate for this, some filters are formed to supply separate power to generate static electricity in the mesh network to collect dust and fine dust in an electrostatic manner and deodorize, as described above, a separate power supply unit By laying it, the cost rises at the time of manufacture, and it becomes a cause of the problem that productivity as a whole falls.

The outer circumferential surface of the innumerable metal wire rods crossing the transverse direction and the longitudinal direction to form pores is formed as "W (double oil)", and a tunnel-shaped space portion is formed inside the bent "W (double oil)" to allow the flow of outside air. A plurality of screens are overlapped to form a mesh network 110 so as to facilitate obstacles, and a plurality of urethanes are used to filter and collect secondary dust through and adjacent to one side of the demister 100. Electrostatic urethane foam 200 is provided with a fine hole 210 to form a sponge of the porous body, and the longitudinal direction so as to filter and collect the dust passing through and adjacent to one side of the electrostatic urethane foam 200 in the third A polypropylene plate 310 having a checkerboard shape with a tip of a synthetic resin material overlapping with each other in a transverse direction, wherein the polypropylene plate 310 is neighbored and overlapped with a plurality of polypropylene plates 310. Screen net 400 and the screen net 400 coupled to the outside of the demister 100, the electrostatic urethane foam 200, polypropylene filter net 300 integrally bundled to protect the guide, and the screen The body is formed in a rectangular frame shape to accommodate the demister 100, the electrostatic urethane foam 200, and the polypropylene filter net 300, which are integrally bundled by the network 400, and connect the rectangular shapes. The frame 510 is formed of a stainless channel having a “c” shape opening toward the inside, and the open ends of the frame 510 are bent from the outside to the inside to be inclined at a vertical tip.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

First, as shown in FIGS. 1 and 2, the present invention includes a demister 100, an electrostatic urethane foam 200, a polypropylene filter net 300, and a screen net 400 that bundles them integrally. And, the demister 100, the electrostatic urethane foam 200, the polypropylene filter net 300 and the screen net 400 is largely composed of a filter case 500 to form a filter by combining inside.

At this time, the demister 100 is perpendicular to the transverse wires of the metal material and the longitudinal wires of the metal material overlap each other to form a pore to form a mesh network 110.

At this time, the diameter of the pores formed by the wire rods is preferably formed to be 0.1mm or more and 3.0mm or less, in order to more effectively collect the dust of various sizes introduced from the outside air.

As shown in FIG. 3, the demister 100 has an outer circumferential surface of a number of wire rods intersecting in the transverse direction and the longitudinal direction to form pores, and formed of “W (double oil)”, and the “W (double oil)” of the bent “W (double oil)”. It is preferable to form a mesh network 110 by overlapping a plurality of screens so that a tunnel-shaped space portion is formed on the inner side so as to disturb the flow of outside air.

Compared to the pores formed in the conventional grid-shaped checkerboard mesh (not shown), the mesh network 110 of the present invention is formed of "W (double oil)" in which one outer circumferential surface of the transverse longitudinal wires is bent in a zigzag form. The tunnel-shaped space portion is formed inside the bent wires, and the outside air introduced into the space portion is bent on the mountain (high edge side) and the valley (low edge side) of the "W (double oil)" type and receives resistance (obstruction). That is, there is an advantage to enable more effective capture than the conventional tunnel penetrated in a straight line.

The pores are narrow by the zigzag wires, and the trapping area of the dust is formed by the "W (double oil)" type tip that is bent in layers even after going back, resulting in high filtration efficiency and dust. The collection rate is high.

In other words, compared to the conventional mesh network formed in a straight line, the mesh network 110 of the present invention consists of "W" (double oil) up, down, left, and right, which maximizes the collection area compared to the conventional mesh network, so that the exchange and washing cycles are maximized. It has the advantage of leading long.

On the other hand, the electrostatic urethane foam 200 is formed to have a plurality of micropores in the urethane so as to filter and collect the dust passing through and adjacent to one side of the demister 100 to have a porous sponge form.

At this time, the micropores cause their own static electricity from the incoming external air dusts, and induces the dusts to stick and collect as they are rubbed with the air passing through them.

That is, when the book base is rubbed on a dry cloth, static electricity is generated without a separate power supply as the paper sticks, which causes friction force to be generated by the outside air passing through the pores formed by the micro holes 210. At this time, the dust of the outside air passing through is stuck to the fine hole 210 and collected.

The sponge-type electrostatic urethane foam 200 is capable of being reused after cleaning, and in particular, its weight is light, and its life is semi-permanent because it is not affected by humidity, temperature, air pollution, etc., which is very durable. have.

On the other hand, the polypropylene filter net 300 is a checkered polypropylene plate with a front end of the synthetic resin material overlapping in the longitudinal and transverse directions so as to filter and collect the dust passing through the neighboring one side of the electrostatic urethane foam (200) 310 is formed, but the polypropylene plate 310 is formed so as to overlap a plurality of neighboring.

At this time, the polypropylene plate 310 is made of a synthetic resin material, light weight and particularly strong electrostatic power to promote the collection of dust once more, to filter the indoor air from the outside air pleasantly and cleanly.

On the other hand, the screen net 400 is coupled to the outside of the demister 100, the electrostatic urethane foam 200, the polypropylene filter net 300 is integrally bundled to protect the guide.

This is because the integrally bundled electrostatic media, that is, the screen net 400, the thinner lamination of the demister 100, the electrostatic urethane foam 200, the polypropylene filter net 300 reduces the area of the installation, By arranging the outer ends of the filters by preventing them from escaping to the outside of the filter case, it is possible to achieve stable fixing during installation and to induce the safety of the operator.

At this time, the screen net 400 is preferably a mesh formed in the pores of more than 1cm 3cm or less to facilitate the inflow of outside air. This is a kind of guide that is installed to prevent the screen net 400 is formed so as not to escape to the outside while supporting the electrostatic media formed in the filter case 500, the dust of the outside air flowing into one side is stacked on the surface of the screen net 400 400 In order to prevent this from happening in order to facilitate the inflow and flow of outside air.

On the other hand, the filter case 500 is a frame-shaped body of a rectangular body to accommodate the demister 100, the electrostatic urethane foam 200, the polypropylene filter net 300 is integrally bundled by the screen net 400 inside The frame 510 connecting the quadrangles is formed of a stainless channel having a shape of “c” which is opened inward, and both ends of the frame 510 are opened inward. A filter tip bending frame 520 is installed to guide the filter 10, which is bent at a predetermined angle and coupled to the filter 10, to be stretched from the outside to the inside, and to be more securely and firmly fixed.

At this time, the tip bending frame 520 of the filter case 500 is preferably bent from the outside to the inclined angle of 1 to 30 ° with respect to the vertical tip.

This is the demister 100, the electrostatic urethane foam 200, the polypropylene filter net 300 is accommodated inside the screen net 400 is more tightly accommodated, which is the frame 510 in the direction of passing outside air By inducing not to protrude outward from the outer circumferential surface, it prevents a worker's safety accident (jamming due to the protruding mesh net), while providing accurate assembly and installation of the equipment.

Next will be described an embodiment of the present invention according to the above-described configuration.

It is coupled to the inner side of the case, but both ends are protected by a screen net to prevent the demister 100, the electrostatic urethane foam 200, and the polypropylene filter net 300, which are accommodated in the case, from protruding or deviating outward. It is formed so as to, the electrostatic filter consisting of the demister 100, the electrostatic urethane foam 200, the polypropylene filter net 300 is sequentially stacked inside the screen net to form an integrated filter.

Contaminants such as dust, fine dust, oil and the like are accommodated in the outside air passing through the electrostatic filter, which is precisely and safely filtered and collected by the present invention having a triple structure.

That is, the outside air (dust, dust) introduced into the first demister 100 is deeply penetrated by the mesh network 110 having a “W (double oil)” shape, and is filtered and collected, in particular, a capture area compared to a conventional mesh network. This maximizes the advantage of inducing a long exchange and cleaning cycle.

On the other hand, a number of fine holes 210 are formed in the urethane foam 200 so that the first filtered dust is collected and filtered secondarily by the electrostatic urethane foam 200 adjacent to the demister 100.

At this time, the fine holes 210 cause their own static electricity from the incoming external air dusts, and induces the dusts to stick and collect as they are rubbed with the air passing through them.

In addition, the remaining dust filtered secondly is formed by the polypropylene filter net 300 to be filtered and collected in the third, which is the end of the synthetic resin material overlapping in the longitudinal and transverse direction checkered polypropylene plate 310 It is formed, but the polypropylene plate 310 is formed so as to overlap a plurality of neighboring.

Since the polypropylene plate 310 is made of a synthetic resin material, the weight is light and the electrostatic force is particularly strong so as to promote the collection of dust once more, thereby filtering the indoor air from the outside air comfortably and cleanly.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
