In particular, the removal of various harmful components is very important in a hospital (especially an operating room, an intensive care unit, etc.), a clean room in a semiconductor production line, a laboratory, a clean room, and the like.

In the related art, where a variety of harmful components are to be removed, an air cleaning system for removing foreign substances such as various harmful components and dust in the air existing in the room has been constructed.

However, the conventional general air cleaning system is simply provided with a plurality of filters, or only to remove the various foreign matter by the electric dust collection method.

That is, the conventional air cleaning system has not been equipped to effectively remove volatile organic compounds (VOC) present in the atmosphere.

Of course, in the related art, there is a situation in which an air purifier capable of removing the volatile organic compounds described above is partially provided in an indoor (eg, an operating room, a laboratory, a semiconductor production line, etc.) which requires an extremely clean state.

However, since the volatile organic compound has a property of being decomposed into various compounds and easily recombined, the volatile organic compound has not been completely removed.

The present invention has been made to solve the above-mentioned problems of the present invention, and an object of the present invention is to provide a new structure of the air cleaning system which enables the removal of volatile organic compounds as well as various foreign substances.

Hereinafter, a preferred embodiment of the air cleaning system of the present invention will be described in more detail.

1 is a state diagram schematically showing an installation structure of an air cleaning system according to a preferred embodiment of the present invention.

That is, the air cleaning system according to the embodiment of the present invention is largely an air flow tube 100, a blowing fan assembly 200, a disassembling unit 300, a water screen unit 400, and an air cooling unit 500. And, it is configured to include a foreign matter filtering unit 600.

Each of the above components will be described in more detail with reference to FIGS. 2 to 6 as follows.

First, the air flow tube 100 is a pipe through which air in the room is introduced and flows.

At this time, the indoor air is introduced into one end of the air flow tube 100, and the indoor air is discharged to the other end.

In particular, the air flow pipe 100 may be formed as a straight pipe in only one direction, as shown, or at least one portion may be formed as a bent or 휜 pipe, although not shown.

Next, the blowing fan assembly 200 is mounted on the conduit of the air flow pipe 100 is configured to force the flow of air.

At this time, the blowing fan assembly 200 is configured to include a blowing fan 210 and the fan motor 220 as shown in FIG.

The blowing fan 210 may be formed as an axial fan, or may be formed as a cross flow fan such as a sirocco fan as shown in the embodiment. In this case, when the blowing fan 210 is formed as a cross flow fan, the air flow side 120 of the air flow pipe 100 shows the flow of air blown by the blower fan above and / or below the blower fan. It is preferable that the flow path guide 230 is further formed so as to be guided to.

In particular, the blower fan assembly 200 is shown in the embodiment of the air flow pipe 100 is installed in a substantially central portion of the pipeline of the air flow.

This is to allow the air flowing in the air flow tube 100 to be uniformly and smoothly blown from the air inlet side 110 to the air outlet side 120.

Of course, if necessary, the blower fan assembly 200 may be installed on the air inlet side 110 of the air flow tube 100, and the blower fan assembly 200 may be installed in the air flow tube 100. It may be installed on the air outlet side 120.

Next, the decomposing unit 300 is installed on the pipeline of the air flow pipe 100, and is configured to decompose the components constituting harmful components or foreign matter in the air flow into fine individual particle units.

At this time, the decomposing unit 300 is a combustion device that can burn various components in the air passing through the portion by heating the inside of the air flow pipe 100 of the air flow pipe 100 with a very high temperature as shown in the accompanying FIG. It is assumed that the embodiment. Here, the combustion device is an electric heater or various devices capable of burning air accordingly.

In particular, the decomposing unit 300 may be installed outside the air flow tube 100, but may be installed inside a pipe of the air flow tube 100 to directly burn air passing therethrough. It is preferable because combustion efficiency can be obtained.

Of course, the decomposing unit 300 may be configured as a laser device configured to provide a laser beam to excite and dissociate constituents constituting harmful or foreign substances in the air, thereby separating the components from each other. It may be composed of a semiconductor room temperature catalytic oxidation device configured to adsorb the substance on the surface of the catalyst to oxidatively decompose the adsorbed contaminants by radicals.

In addition, the embodiment of the present invention suggests that the decomposition part 300 is installed between the air inlet side 110 of the air flow tube 100 and the blower fan assembly 200.

This is to firstly decompose volatile organic compounds (VOC: Volatile Organic Compounds) in the air sucked from the room into fine molecular units.

Next, the water screen unit 400 is installed on the conduit of the air flow tube 100, and supplies water to the air flowing in the air flow tube 100 to the decomposition unit 300 from the air It is a series of configurations which can remove the various components decomposed | disassembled by air again from air.

At this time, the water screen unit 400 is configured to include a water supply assembly 410, the reservoir 420, and the drainage assembly 430 as shown in FIG.

The water supply assembly 410 is configured to inject water toward the air passing through the portion (space provided with the water screen unit), and comprises a spray nozzle 411 and the flow path opening and closing valve 412. At this time, the injection nozzle 411 is preferably provided on the upper portion of the water screen unit 400.

In addition, the reservoir 420 is a kind of reservoir for storing water supplied by the water supply assembly 410 and removing contaminants from the air. The reservoir 420 is preferably provided in the bottom side space of the water screen unit 400. This is to allow the dropped water to be received in the space on the bottom side of the water screen unit 400 when the water injected into the flowing air falls by its own weight.

In addition, the drainage assembly 430 is a kind of pump or a flow path open / close valve configured to selectively drain water stored in the reservoir 420.

At this time, the water in the reservoir 420 should be drained as often as necessary, which is a state that contains a lot of pollutants in the stored water, and if the reservoir 420 is not frequently drained water stored therein This is because it can overflow rather contaminate the inside of the air flow pipe (100). Of course, the water in the reservoir 420 may be reused to purify the air through the water supply assembly 410 as necessary.

Most preferably, the water screen unit 400 configured as described above is installed between the disintegrating unit 300 and the blower fan assembly 200 among the pipelines of the air flow pipe 100.

This, when considering that the decomposition unit 300 is composed of a combustion device in the embodiment of the present invention, the dust is generated as the air is burned while passing through the decomposition unit 300, such dust is relatively This is because it is necessary to remove it because it is carried on the air in a light state.

Of course, the water screen unit 400 also has an effect of primarily cooling the air heated by the decomposition unit 300.

On the other hand, the above-mentioned flow of air passing through the interior of the water screen 400 is preferably to be flowed for a long time.

This is to prevent the blower fan assembly 200 from being damaged due to the high temperature heat by allowing the air of the high temperature state passed through the decomposition part 300 to be sufficiently cooled.

To this end, the embodiment of the present invention proposes to install at least one guide plate 440 in a zigzag form alternately along the upper side and the lower side of the inner conduit of the water screen unit 400.

That is, since the air is zigzag flow guided by the guide plate 440, the air can flow in the water screen unit 400 for the longest time as well as the contaminants and Removal of foreign matter can be made more smoothly.

Next, the air cooling unit 500 is installed on the conduit of the air flow pipe 100, it is configured to cool the air flowing along the air flow pipe (100).

The reason for cooling the air is because the air passing through the decomposing unit 300 is in a high temperature state as described above, and there is a reason for causing a decrease in temperature thereof, but substantially to remove moisture, that is, moisture from the air. to be.

At this time, the air cooling unit 500 is installed to surround the outer circumferential surface of the air flow tube 100 as shown in Figure 5 suggests that the low-temperature refrigerant is composed of a heat exchanger flows.

Of course, the air cooling unit 500 may be installed on the inner conduit of the air flow pipe (100). However, in this case, as the air cooling unit 500 plays a role of the flow path resistance to the air, the load of the blower fan assembly 200 is increased, thereby lowering the blowing efficiency. Therefore, the air cooling unit 500 is most preferably provided on the outside of the air flow pipe (100).

In particular, the air cooling unit 500 as described above is preferably provided between the blower fan assembly 200 and the air outlet side 120 of the air flow pipe 100 of each of the air flow pipe (100). Do.

Next, the foreign matter filtering unit 600 is installed on the conduit of the air flow pipe 100, and is configured to directly remove various foreign matters contained in the flowing air.

The foreign matter filtering unit 600 is preferably configured to include at least one filter as shown in FIG.

At this time, since each filter is a final means for removing foreign matters from the air, foreign matters such as fine dust should be configured to remove as much as possible.

To this end, an embodiment of the present invention suggests that at least one of the above filters is composed of a HEPA filter, a pre-filter, a carbon filter, or the like.

Of course, it is more preferable that each filter of the foreign substance filtering unit 600 further includes a filter for removing an odor component, but since the contaminants such as the odor component are mostly removed while passing through each other part, it must be present. It is not.

In particular, the foreign matter filtering unit 600 is preferably installed between the air cooling unit 500 and the air outlet side 120 of the air flow pipe 100 of each of the air flow pipe (100).

Hereinafter, a process of removing various contaminants and foreign substances contained in the indoor air by the air cleaning system according to the embodiment of the present invention will be described.

First, when the operation of the air cleaning system is performed, the blower fan assembly 200, the disassembling unit 300, the water screen unit 400, and the air cooling unit 500 are respectively driven.

Among these, the blowing fan assembly 200 is driven to blow air in the room.

In this case, the indoor air affected by the driving of the blower fan assembly 200 is introduced into the air flow pipe 100 through the air inlet side 110 of the air flow pipe 100, and subsequently the air flow pipe ( After flowing along the 100, it is discharged back to the room through the air outlet side 120 of the air flow pipe (100).

At this time, the air contains a variety of pollutants (volatile organic compounds such as pathogens, foreign substances and harmful compounds) existing in the atmosphere of the room.

In addition, the air is combusted while passing through the decomposing unit 300 during the above-described series of processes.

As a result, since various contaminants in the air passing through the decomposition unit 300 are burned, the primary purification of the air is performed.

At this time, volatile organic compounds are also broken down into fine molecular units as they are burned.

However, the primary purified air contains ash left after the pollutant has been burned.

Therefore, the air passing through the decomposition unit is provided to the water screen unit 400 while flowing along the air flow tube 100 in a state of containing ash in the dust state.

At this time, the water supply assembly 410 constituting the water screen unit 400 is operated to spray water into the space in which the air flows.

Accordingly, the air passing through the water screen unit 400 is stored in the reservoir 420 together with the sprayed water while various foreign substances contained therein, that is, ash is removed again by the sprayed water. At this time, the water and foreign matter stored in the reservoir 420 is selectively drained by the operation of the drainage assembly 430.

In addition, the air is introduced into the water screen unit 400 in a high temperature state through the decomposition unit 300, but in a state where the temperature is reduced due to the water sprayed while passing through the water screen unit 400 Spills.

In particular, since a plurality of guide plates 440 are provided in a zigzag form in the water screen unit 400, the air passes through the water screen unit 400 for a long time, and thus the air is more excellent. Purification efficiency can be achieved and reduced to lower temperatures.

In addition, the air from which the contaminants are removed again by the above-described series of processes passes through the air blowing fan assembly 200, and then continues through the air cooling unit 500.

In this case, when the air cooling unit 500 is configured as a heat exchanger through which a low-temperature refrigerant flows, air passing through a portion provided with the air cooling unit 500 is condensed at the same time as the temperature is reduced.

Therefore, moisture or moisture contained in the air is condensed and separated from the air, and the air passing through the air cooling unit 500 continues to pass through the foreign matter filtering unit 600.

In this case, the foreign matter filtering unit 600 includes a plurality of filters, and considering that the HEPA filter is included in each filter, the foreign matter remaining in the air passing through the foreign matter filtering unit 600 is filtered out of the foreign matter. Completely removed from unit 600.

As a result, the air once again purified while passing through the foreign matter filtering unit 600 is discharged back into the room through the air outlet side 120 of the air flow pipe (100).

As such, the air that is purified while passing through the air cleaning system according to the embodiment of the present invention is first burned while passing through the decomposing unit 300, before the molecules of various components separated from each other are recombined with the water screen unit 400. And while passing through the air cooling unit 500 and the foreign matter filtering unit 600 are filtered from the air, respectively.

Therefore, the air passing through the air purification system can achieve a state in which volatile organic compounds are completely removed, as well as various dusts and fine foreign matters in the air.

As described above, since the air cleaning system according to the embodiment of the present invention can remove the volatile organic compounds contained in the air, the air purification performance is maximized.

In particular, the volatile organic compounds are filtered out of the air sequentially passing through the water screen unit, the air cooling unit and the foreign matter filtering unit before being recombined in the state of being decomposed into the unit molecular state by the decomposing unit. It has the effect of being removable.

In addition, the air cleaning system according to an embodiment of the present invention can be gradually lowered in the course of passing the high mild air while passing through each of the other components while passing through the decomposition portion to finally discharge the air toward the room It does not raise the temperature of the room, and has the effect of not affecting the temperature change of the room.

In particular, since the air cooling unit can completely remove the moisture or moisture contained in the air has an effect that can maintain the indoor environment in a comfortable state.

In addition, the air cleaning system according to the embodiment of the present invention can remove various dusts and foreign matters from the air by using water, and the various dusts and foreign matters can be completely removed from the air by each filter. Purification performance is improved.
