CIRCULATION AIR PURIFIER SYSTEM AND APPARATUS OF THE SAME SYSTEM BASED HUMAN RESPIRATORY CIRCULATORY SYSTEM

The present invention relates to a circulating air purification system mimicking the human respiratory circulatory system and a device therefor, and more particularly, to a circulating air purification system imitation of the human respiratory circulatory system capable of preventing deterioration of indoor air quality due to outdoor pollutants outside the target purification space; and It's about the device.

In general, an air purifying system and its device (air purifier) include all systems and devices disposed inside a target purifying space (hereinafter abbreviated as 'indoor') and operated to improve deteriorated indoor air quality.

Indoor air quality is continuously deteriorated by the activities of occupants. For example, generation and accumulation of particulate matter (PM) due to cooking activities, continuous accumulation of carbon dioxide due to respiration of occupants, or volatile organic compounds (VOCs) due to cooking activities and use of high molecular compounds ), and the like.

Such deterioration of indoor air quality, in particular, is difficult to be resolved with a conventional air circulation type air purifier due to gas pollutants (Gas Pollutant, GP) such as carbon dioxide (CO2) and VOC, and the polluted indoor air is discharged. At the same time, it is common to eliminate it through outdoor air circulation that introduces a large amount of outdoor air.

However, the deterioration of outdoor air quality caused by fine dust (PM2.5) with a diameter smaller than 2.5 μm limits indoor air quality improvement activities through the inflow of external air. That is, indoor air purification requires effective material exchange and effective material interception indoors and outdoors.

In order to solve this problem, a conventional general air purification system has adopted a method of introducing purified outside air into a room by operating an air filtering system. However, in the case of the general air filtering system, 1) purification efficiency is reduced due to the absence of an effective exhaust mechanism, 2) periodic filter replacement is required, and 3) gaseous pollutants (tropospheric ozone (O3), etc.) enter the room. It has limitations such as

On the other hand, in order to solve this problem, a method of purifying air by spraying water on inhaled polluted air has been disclosed. Since water is not evenly mixed, there is a problem that the filtration efficiency for dust and the like is very low. This spray-type air purification is suitable for preventing and controlling a specific polluted area, but is not suitable for cleaning a general office space or the interior space of a home.

The present invention has been devised to solve the above technical problem, and at the same time as the accumulated airborne solid matter (PM) in the room, the gas pollutant (GP), which cannot be removed by the conventional filter technology, is introduced into the outdoor pollutant. An object of the present invention is to provide a circulating air purification system and device that mimic the human respiratory circulatory system, which can be continuously removed without the need for continuous removal.

It is a conceptual diagram, and FIG. 5 is a detailed operation diagram of FIG. 4 .

An embodiment of the circulating air purification system and the device imitating the human respiratory circulatory system according to the present invention, as shown in FIGS. 1 to 5 , a purification space boundary portion 10 defining a target purification space C; A purification unit ( 100A, 100B) (hereinafter, it may be defined as the circulating air purification apparatus 100A, 100B according to the present invention).

Here, the target purification space C defined (limited) by the purification space boundary portion 10 may be a concept including an independent indoor space closed from the outside. That is, it can be understood as a 'wall' that partitions each indoor space of a general building, as well as any partition means that do not mix with each other unless an artificial flow force is provided by blocking indoor and outdoor air. can As an example, as shown in FIG. 8 to be described later, a transparent compartment case constructed for an experiment may also correspond to this.

In one embodiment of the present invention, the target purification space C as the space inside the purification space boundary 10 provides a mechanism to be purged through the bubble surface on the gas flow path formed through the pressure gradient. This is a development of the working principle of the respiratory circulatory system of the human body, and as shown in FIG. 3 , 'external respiration', which is a gas exchange that occurs in the lungs of the human body, is the gas that occurs in the capillaries in each end tissue (Peripheral Tissue) inside the body. It is an application and development of 'internal respiration', which is exchange, and the principle of blood circulation that mediates these two actions. The purification space of the present invention corresponds to the inside of the human body, and the internal air purification unit 100A and the external air purification unit 100B correspond to the capillaries and lungs inside the end tissues of the body where 'internal respiration' and 'external respiration' occur, respectively. , blood may be understood as corresponding to the working fluid circulating between the internal air purification unit 100A and the external air purification unit 100B. A more specific mechanism of gas exchange will be described in detail in each corresponding section.

The purification units 100A and 100B, as shown in Figs. 1 and 3, are located inside the purification space boundary portion 10 and are driven for practical air purification. The internal air purification unit 100A and the purification space It may include an external air purification unit 100B that is located outside the boundary portion 10 and is connected in communication with the internal air purification unit 100A to circulate the liquid.

Referring to FIG. 3 , the external air purification unit 100B serves as a gas exchanger outside the purification space (corresponding to the inside of the human body) like the lungs, and the internal air purification unit 100A is a capillary at the end of the human body. Like blood vessels, it acts as a gas exchanger. The internal air purification unit 100A and the external air purification unit 100B have their circulation mediated by a fluid corresponding to human blood (a working fluid to be described later), for example, an external air purification unit such as oxygen (O2). The gas dissolved in the liquid (working fluid) circulating through 100B may be vaporized and then supplied to the room after being moved to the internal air purification unit 100A according to the liquid circulation, and conversely, internal air such as carbon dioxide (CO2) The gas dissolved in the liquid (working fluid) circulated through the purification unit 100A may be vaporized after being moved to the external air purification unit 100B and discharged outdoors.

That is, the internal air purifying unit 100A performs a function to substantially purify the air in the target purifying space C by sucking the air inside the target purifying space C to be purified, and the external air purifying unit 100B may perform a function of discharging a purification target material in a polluted state purified and filtered through the internal air purification unit 100A to the outside, or supplying a purification target material to be filtered to the internal air purification unit 100A side. .

The internal air purifying unit 100A and the external air purifying unit 100B are provided so that a liquid (a working fluid, which will be described later) flows in communication with each other, and is purified by moving a substance to be purified in a contaminated state in the liquid through a gas exchange mechanism. function will be performed.

In more detail, the internal air purifying unit 100A and the external air purifying unit 100B are, as shown in FIGS. 1 to 3 , the air inside the purified space boundary 10 or the outside of the purified space boundary 10 . The suction chamber C1 for sucking in the air (hereinafter referred to as 'outside air') of It may include a purification case 110 including an exhaust chamber C2 that exhausts air to the side where outside air exists.

The internal air purifier 100A sucks in the outside air existing inside the purification space boundary 10 through the suction chamber C1, and sucks the outside air sucked in through the suction chamber C1 with the exhaust chamber C2. After flowing over the gas flow path formed through the pressure gradient, and allowing substantial gas exchange to occur while passing through the purification chamber C3 positioned therebetween, the purified air flowing into the exhaust chamber C2 is again fed back to the purification space boundary (10) Repeat exhausting to the side where the outside air inside exists.

The external air purification unit 100B also sucks in the outside air existing outside the purification space boundary 10 through the suction chamber C1, and the outside air sucked in through the suction chamber C1 is pressured with the exhaust chamber C2. After flowing over the gas flow path formed through the gradient, and allowing substantial gas exchange to occur while passing through the purification chamber C3 located therebetween, the purified air flowing into the exhaust chamber C2 is again fed back to the purification space boundary ( 10) Repeat exhausting to the side where the outside air exists.

Here, the liquid inside the purification chamber C3 may be a working fluid that is either water or a polar fluid having a predetermined polarity. The working fluid may flow in one direction to communicate with each of the purification chambers C3 of the internal air purification unit 100A and the external air purification unit 100B.

Here, a catalyst material such as CaCO3 or NaHCO3 may be added to the working fluid for selective and effective removal of specific gaseous pollutants (GP). CaCO3 and NaHCO3 are for effective capture of carbon dioxide (CO2). Selective and effective removal of gaseous pollutants through such catalytic materials may be possible through pH adjustment of the working fluid (eg NaHCO3) or salt formation (eg CaCO3) or the like.

1 and 3, the working fluid is purified air that is polluted air existing in the outside air inside the purification space boundary portion 10 sucked through the suction chamber C1 in the internal air purification unit 100A. Gas exchanges in a form that dissolves the target substance.

Conversely, the working fluid, as shown in FIGS. 1 and 3 , is contaminated air present in the outside air inside the purified space boundary portion 10 sucked through the suction chamber C1 in the outside air purification unit 100B. Gas exchange in a form that dissolves the substance to be purified by phosphorus.

Meanwhile, the internal air purification unit 100A and the external air purification unit 100B are disposed to be partitioned between the purification chamber C3 and the intake chamber C1 and the boundary between the purification chamber C3 and the exhaust chamber C2. and may further include a through-hole membrane (THM) that prevents loss of the working fluid filled in the purification chamber C3 and generates air bubbles of a predetermined size in the purification chamber C3 .

The penetrating membrane is made of a special material that passes gas but does not pass liquid (or working fluid) on a gas flow path formed through a pressure gradient. It plays a role in generating countless number of air bubbles below the size.

Here, the penetration layer may include a hydrophobic elastomer THM. The hydrophobic elastomer penetrating film preferably has elasticity such that the size of the bubbles formed in the purification chamber C3 on the surface of the film is limited to a predetermined size or less.

In general, a well-known technique for the generation of small gas bubbles (bubbles) is to use a porous solid material. After immersing a porous solid material (eg, a piece of wood of a specific type, porous ceramic, etc.) in a fluid, and then applying air pressure into the fluid, fine gas bubbles with a level of several micrometers can be generated. However, since the use of such a porous solid material acts as a filter itself, in the case of inflow of a gas including a gaseous suspended solid material (PM), there is a concern about a continuous decrease in performance due to blockage of the pipeline.

Therefore, in the present invention, the penetrating film is applied as a hydrophobic elastomer penetrating film, but it is preferable that the size of the cells is limited to have elasticity generated below the predetermined size described above.

When a pressure gradient is formed at both ends of the hydrophobic elastomer penetrating membrane, it has a characteristic that it vibrates while repeating expansion and contraction without the aid of a device that applies additional vibration force. In other words, after the gas passes, it contracts and expands gradually. This vibration suppresses bubble growth on the surface of the penetration membrane, thereby continuously generating fine gas bubbles (bubbles). Able to know.

In the case of a conventional air-filter, as shown in FIG. 4 , in principle, only particulate matter (PM) in the gas phase can be filtered, and gaseous pollutants contained in the gas (Gaseous) Pollutant, GP) had a problem that could not be removed. However, recently, there have been commercial examples of limited gaseous pollutant (GP) removal using adsorbent porous materials such as activated carbon, but there are distinct limitations for low molecular weight substances such as carbon dioxide (CO2) or ozone (O3). .

The circulating air purification system and its device imitation of the human respiratory circulatory system according to an embodiment of the present invention solve the problems of the above-described air filter, so that not only the airborne solid particles (PM) but also the gaseous pollutants (GP) are easy It starts by focusing on the principle of actively supplying beneficial air components to the interior of the purified space boundary portion 10.

In more detail, the above-described gas exchange principle is, as shown in FIG. 5 , gaseous suspended solids (PM) and gaseous pollutants (GP) contained in the outside air sucked through the suction chamber C1 are It is trapped in an air bubble of a predetermined size or less formed by the penetrating membrane in the purification chamber C3 and moves in the purification chamber C3 in the flow direction of the gas formed through the pressure gradient.

At this time, when the bubble is enlarged, it can be seen that the dissolution and adsorption phenomenon due to the difference in the internal partial pressure of the bubble occurs very actively at the interface where the bubble and the liquid (or working fluid) meet. The gaseous pollutants (GP) inside the relatively small bubbles are dissolved as a liquid (or working fluid), and the gaseous suspended solid substances (PM) inside the relatively large bubbles are dissolved by the liquid (or working fluid). It is adsorbed and flows to the liquid side.

As described above, as an example to which a similar technology of the air purification method using air bubbles in the fluid (working fluid or water) is applied, there is a type of spraying a liquid to purify the air in the target purification space (C). . This is similar to the embodiment of the present invention in terms of air purification using bubbles, but in an embodiment of the circulating air purification system and apparatus according to the present invention, bubbles are formed in the liquid to purify along a predetermined air flow path. It has a technical composition opposite to that for purifying the target material.

For convenience, the former purification system is called a water-in-air system, and an embodiment of the present invention is called an air-in-water system. Similarly, even in the air purification method using bubbles, the movement of the purification target material through the liquid-gas interface formed by the bubbles is more smoothly performed in a closed space (eg, bubbles), so it is a water-in-air system. It can be seen that the purification efficiency of the air-in-water system according to an embodiment of the present invention is very superior to that of the former technique. In the case of a water-in-air system, mass transfer from a gas to a liquid is a principle in which diffusion and convection occur in a complex manner, so the efficiency of mass transfer is significantly lower than that of an air-in-water system.

Meanwhile, the internal air purifying unit 100A and the external air purifying unit 100B may further include a pressure gradient forming unit 130 that forms the above-described pressure gradient so that the air flow of the outside air is achieved.

As shown in FIGS. 1 and 2, the pressure gradient forming unit 130 includes an air suction fan 130a provided on the suction chamber C1 side to suck outside air at a predetermined suction pressure, and an exhaust chamber ( It may be provided as an air suction fan 130b provided on the C2) side to discharge outside air at a predetermined discharge pressure.

In one embodiment of the present invention, the pressure gradient forming unit 130 is described as being limited to the air intake fan 130a and the air intake fan 130b, respectively, but the outside air is sucked in and exhausted through the intake chamber C1. In discharging through the chamber (C2), it will be of course possible to adopt a configuration having any name as long as it is possible to form a predetermined pressure gradient.

Preferably, the pressure gradient forming unit 130 may be operated so that the pressure on the side of the intake chamber (C1) is greater than the pressure on the side of the exhaust chamber (C2). Therefore, after the outside air is easily introduced into the suction chamber C1 by the suction pressure of the air suction fan 130a, the air between the suction chamber C1 and the purification chamber C3 is formed on the working fluid of the purification chamber C3. The boundary between the purification chamber C3 and the exhaust chamber C2 after flowing while forming a predetermined gas flow path in the form of innumerable bubbles of a predetermined size or less formed by the lower penetration layer 120a disposed to partition the boundary It flows into the exhaust chamber C2 through the upper penetrating membrane 120b disposed to partition the will be.

On the other hand, the internal air purifying unit 100A and the external air purifying unit 100B communicate with each of the purifying chambers C3, the working fluid filled in the purifying chamber C3 of the internal air purifying unit 100A. The working fluid discharge pipe 150 provided with a discharge pump P1 for discharging to the purification chamber C3 of the external air purification unit 100B communicates with each purification chamber C3, and the external air purification unit 100B A working fluid supply pipe 160 provided with a supply pump P2 for supplying the working fluid filled in the purification chamber C3 of the internal air purification unit 100A to the purification chamber C3 of the internal air purification unit 100A may be further included.

Both ends of the working fluid discharge pipe 150 and the working fluid supply pipe 160 communicate at different positions of the purification chamber C3 of the internal air purification unit 100A and the purification chamber C3 of the external air purification unit 100B, respectively. can be very provided. The discharge pump P1 of the working fluid discharge pipe 150 and the supply pump P2 of the working fluid supply pipe 160 are operated in consideration of the internal partial pressure of bubbles formed by the outside air in each purification chamber C3. This is preferable. The internal partial pressure of the bubble may be set differently depending on the type of the purification target material.

An air purification process according to an embodiment of the circulating air purification system and the device imitation of the human respiratory circulatory system according to the present invention configured as described above will be briefly described with reference to the accompanying drawings.

1 and 3, the pressure between the intake chamber C1 and the exhaust chamber C2 through the pressure gradient forming unit 130 of the internal air purification unit 100A and the external air purification unit 100B to form a gradient.

Then, in the internal air purification unit 100A located inside the purification space boundary portion 10, for example, the outside air containing gaseous pollutants GP such as gaseous suspended solids (PM) and carbon dioxide (CO2) Carbon dioxide (CO2) and The same gaseous pollutants are dissolved as a working fluid at the interface of the bubbles, and a relatively large gaseous suspended solid material (PM) is adsorbed to the working fluid and purified by an operation of being collected by the working fluid, and the remaining bubbles are removed from the upper penetrating membrane 120b. ), being collected into the exhaust chamber C2 and then exhausted repeatedly. At this time, after gaseous material such as oxygen (O2) is dissolved from the external air purification unit 100B to the working fluid side of the purification chamber C3, the purification chamber of the internal air purification unit 100A through the working fluid supply pipe 160 ( After flowing to C3), it can be supplied by being vaporized into the bubble by controlling the internal partial pressure of the bubble.

And, in the outside air purification unit 100B located outside the purification space boundary portion 10, for example, the outside air containing gaseous substances such as gaseous suspended solids (PM) and oxygen (O2) is sucked into the intake chamber (C1). ) flows toward the purification chamber C3, and is collected inside the bubbles formed to a size smaller than a predetermined size by the lower penetration film 120a and moved to the exhaust chamber C2, gaseous substances such as oxygen (O2) Gas-phase suspended solid matter (PM), which is dissolved as a working fluid at the interface of the bubbles and has a relatively large size, is purified by adsorbing to the working fluid and collected by the working fluid, and the remaining bubbles are exhausted through the upper penetrating membrane 120b. After being collected into the chamber (C2), the exhaust is repeated.

Therefore, the purified air and oxygen (O2) required in the target purification space C are continuously supplied, and at the same time, the pollutants of the target purification space C, such as gaseous suspended solid matter (PM) and carbon dioxide (CO2), are The gaseous pollutants (GP) can be removed by continuously dissolving to the working fluid side.

6 is a graph showing the reduction amount by contamination concentration, FIG. 7 is a graph showing the contamination removal time for each bubble size, and FIG. It is a photograph comparing the state of the purification space (C).

Referring to FIG. 6 , adsorption and dissolution of contaminants (PM and GM) at the interface of bubbles are predicted to proceed by diffusion.

In addition, referring to FIG. 7 , it can be experimentally proven that the smaller the bubble size, the shorter the removal time of the contaminants (PM and GM).

In addition, referring to FIG. 8 , after 4 minutes have elapsed from the initial state, contaminants present inside the purification space boundary portion 10 are remarkably removed by the circulating air purification system and the device according to an embodiment of the present invention. And it can be visually confirmed that the reduction.
