Description

Air purifier using bubbles}

The present invention relates to an air purifying device, and more particularly, to an air purifying device using air bubbles, which continuously decomposes air bubbles containing dust while passing through a filter unit, and purifies the air in the air bubbles by adsorbing the dust contained in the air bubbles to water.

In general, an air purifier is a device for removing dust or soot in the air, and includes an air filter, an air washer, and an exhaust device for nuclear facilities.

These air purifiers are selected according to the size and concentration of dust, and usually remove dust by passing air through a filter medium.

Conventional general air purifiers filter out dust by forcibly passing air through an air filter (eg, HEPA filter) having a vent smaller than fine dust. In order to increase the amount of fine dust removal, the area of the filter becomes very large, and accordingly, the energy consumption is improved and the clogging cycle of the filter is increased.

Patent Document 1 shows an air purifying device using a conventional micro-bubble generator. Referring to this, an upper body having a plurality of air inlets formed on a wall in a hollow shape, a lower body positioned at the lower portion of the upper body and receiving water therein and fastened to the upper body, and an upper and lower connecting means installed to connect the upper and lower parts of the body to maintain a connection state of the upper and lower parts of the body, one end of which is located on the upper part of the body, the other end of which is located at the lower part of the body so as to be submerged in water. It consists of a bubble generator.

An air circulation fan for forcing air introduced through the air inlet to be supplied to the microbubble generating unit is formed at an upper end of the microbubble generating unit.

Here, the micro-bubble generating unit air inlet is formed at the upper end of the micro-bubble generating unit, and the micro-bubble generating unit air discharge unit is formed at the lower end opposite to the micro-bubble generating unit air inlet.

That is, when air is supplied through the air inlet, the air is forcibly supplied to the microbubble generator air inlet of the microbubble generator by the air circulation fan, and in that state is guided to the microbubble generator and discharged into the water through the air outlet of the microbubble generator.

At this time, the air discharged from the micro-bubble generating unit air discharge unit generates bubbles in the water and allows the fine dust contained in the air to be adsorbed to the water to remove the fine dust contained in the air.

However, in Patent Document 1 as described above, some of the fine dust contained in the air remains in bubbles generated in water in a state that is not adsorbed to water, and in the process of bubbles containing fine dust rising to the surface of the water and bursting, fine dust in the bubbles is released into the air. There is a problem that the reliability of the product is lowered due to the deterioration of the purification function.

The distribution protrusions 302 of the filter unit 300 are formed continuously so as to form a zigzag structure from top to bottom, and spaced apart from each other by a predetermined distance to pass the decomposed air bubbles B therebetween.

The distribution protrusion 302 of the filter unit 300 is formed in an inverted triangle shape with an upper and lower narrow structure.

The blower 400 is connected to one surface of the housing 100 and supplies polluted air to the lower space of the housing 100 partitioned by the partition plate 200 .

The blower 400 is connected to the extension tank 103 to push water in the extension tank 103 toward the lower space of the housing 100 and simultaneously supplies air to the lower space of the housing 100.

The blower 400 supplies polluted indoor air or polluted air in the air to the housing 100 .

The water supply pipe 500 is connected to and installed on one side of the housing 100, and a water supply valve 500a is formed on the outer surface to supply water to the lower space of the housing 100 partitioned by the partition plate 200.

The water supply pipe 500 continuously supplies water so that the water in the housing 100 reaches a predetermined level, so that the filter unit 300 installed in the housing 100 is immersed in water.

The water supply valve 500a is connected to the water level sensor 100b of the housing 100 and is opened and closed in response to the water level detected by the water level sensor 100b located at the top and bottom.

The air purifier using air bubbles according to the present invention configured as described above is used as follows.

First, the water supply valve 500a of the water supply pipe 500 connected to the housing 100 is opened, and water is continuously supplied into the housing 100 through the water supply pipe 500 so that the water in the housing 100 reaches a predetermined water level.

At this time, when the water level of the water supplied into the housing 100 rises gradually and is detected by the water level sensor 100b installed on the upper end of the inner wall of the housing 100, the water level sensor 100b transmits a signal to the water supply valve 500a of the water supply pipe 500, and the water supply valve 500a receiving this signal is closed and the water supply pipe 500 is blocked.

Here, the water supply pipe 500 is connected to the extension water tank 103 connecting the housing 100 and the water supply pipe 500, and by supplying water into the extension water tank 103, the water in the extension water tank 103 is pushed by the pressure of the water flowing through the water supply pipe 500 and continuously supplied to the housing 100.

That is, the water supplied into the housing 100 through the extension tank 103 reaches a predetermined water level in the housing 100, and at the same time, a predetermined amount of water in the extension tank 103 is supplied. Maintained.

Then, when the air blower 400 is driven to forcibly supply polluted air in the air or indoor space into the extension tank 103, the water in the extension tank 103 is pushed out by the pressure of the air and introduced into the lower space of the housing 100 partitioned by the partition plate 200.

Then, the water accommodated in the lower space of the housing 100 is moved toward the bubble generating hole 201 of the partition plate 200 by air pressure, and at this time, air and water are simultaneously passed through the bubble generating hole 200, and bubbles B are generated in the bubble generating hole 201.

In addition, the bubbles B generated in the bubble generating hole 201 soar directly upward toward the filter part 300 and then collide with the support plate 301 of the filter part 300 inclined at a predetermined angle to move upward along the support plate 301.

Here, the bubbles B moving along the support plate 301 collide with the inverted triangular distribution protrusions 302 and are disassembled into a pair adjacent to each other with respect to the distribution protrusions 302. At this time, the dust contained in the bubbles B is adsorbed to water to remove the dust in the bubbles B.

Thereafter, the mutually decomposed air bubbles (B) pass between the distribution protrusions 302, and then collide with the other distribution protrusions 302 in the same manner as described above, and disintegrate into a pair adjacent to each other based on the distribution protrusions 302.

That is, the bubbles B moving along the support plate 301 are decomposed while continuously colliding with the plurality of distribution protrusions 302 formed on the support plate 301, and their diameter gradually decreases. In the process of being decomposed, the dust contained in the bubbles B is adsorbed to water and the air inside the bubbles B is purified.

Then, when bubbles B rise to the surface of the water in the housing 100 after passing through the filter unit 300, the bubbles B burst and the purified air is dispersed above the housing 100.

On the other hand, when the air is purified by the filter unit 300 as described above, contaminants float to the surface of the water in the housing 100 or submerge in the water and sink to the bottom surface of the housing 100 .

At this time, the pollution level measuring sensor 100a installed in the housing 100 continuously measures the water pollution level in the housing 100, and if the water pollution level in the housing 100 rises above a predetermined pollution concentration, the pollution level measuring sensor 100a transmits a signal to the control valve 102a to open the control valve 102a.

Then, the water in the housing 100 is discharged to the outside through the discharge pipe 102 opened by the control valve 102a. At this time, the pollutants floating on the surface of the water are discharged through the discharge pipe 102 located at the upper end of the discharge pipe 102, and the contaminants settled on the bottom surface of the housing 100 are discharged through the discharge pipe 102 located at the lower end.

In addition, as the water in the housing 100 is discharged, the water level is gradually lowered. At this time, when the water level is detected by the water level sensor 100b installed at the lower end of the inner wall of the housing 100, the water level sensor 100b transmits a signal to the control valve 102a to close the discharge pipe 102 and simultaneously transmits a signal to the water supply valve 500a to supply the water supply pipe 50 0) open.

Thereafter, water is supplied to the extension water tank 103 through the open water supply pipe 500, and the water in the extension water tank 103 is pushed by the pressure of the water flowing through the water supply pipe 500 and supplied into the housing 100.

In addition, water is continuously supplied into the housing 100 so that the water level gradually increases. At this time, the water level sensor 100b installed on the upper end of the inner wall of the housing 100 detects the water level and shuts off the water supply valve 500a.

Then, water in a clean state is supplied into the housing 100, and then, when air is forcibly supplied to the blower 400 in the same manner as above, bubbles B are generated through the bubble generating hole 201, and the bubbles B are continuously decomposed to remove dust contained in the bubbles B to purify the air.

As described above, the bubble B containing dust is generated in the bubble generating hole 201 of the partition plate 200, and the bubble B is continuously decomposed in the filter unit 300 to remove the dust contained in the bubble B to purify the air. It is possible to remove the fine dust of, and also, as the bubble (B) is continuously decomposed, it is changed to a small diameter, so that the fine dust contained in the bubble (B) can be precisely removed, and the bubble (B) from which the fine dust is removed rises to the surface of the water surface. In the process of bursting, the purified air in the bubble (B) is supplied into the air through the air outlet 101, and purified air can be supplied to the atmosphere or to the indoor space.
