Nowadays, as most of our lives are done indoors, awareness of the importance of the indoor environment is increasing. is the trend

However, most air purifiers are simple filtration devices that filter and re-supply various impurities contained in indoor air, and have limitations in removing harmful microorganisms such as viruses and bacteria contained in the air. There is an insufficient point in preventing damage from infection or contamination by harmful bacteria.

That is, the existing air purifiers have a limitation in preventing or treating diseases by eradicating primary infection and dormant bacteria or viruses in the respiratory tract in the human body.

Moreover, the need for air sterilization and disinfection is increasing, especially in places where hygiene management is strictly required, such as hospitals, restaurants, or kitchens. Even for workers who work underwater and people who need breathing air for medical purposes, thorough preparation is required to provide clean, purified air that is not contaminated with various bacteria.

Coronavirus Infectious Disease-19, an epidemic disease that recently occurred in Wuhan City, Hubei Province, China, is also called 'Wuhan Pneumonia', 'Novel Coronavirus Infectious Disease' or 'Corona 19', and is a virus caused by a variant of the coronavirus. It is a sexual disease.

Initially known only as a respiratory infectious disease of unknown cause, it is believed to be a new type of coronavirus such as SARS (severe acute respiratory syndrome) that was prevalent in 2003 and MERS (Middle East Respiratory Syndrome) that was prevalent in 2012. It was revealed on January 7th.

The World Health Organization (WHO) declared a public health emergency of international concern (PHEIC) on January 30 due to the spread of COVID-19 to many countries around the world.

Accordingly, prevention is essential because there is no direct treatment method for COVID-19, and the Korea Centers for Disease Control and Prevention recommends washing and drying hands frequently for at least 30 seconds in running water before and after going out based on the characteristics of this disease that is transmitted through the respiratory tract. It is recommended to wear a sanitary mask when going out and prevent transmission through breathing.

In light of the above circumstances, it is necessary to take active interest and action to prevent infection from viruses or bacteria, as well as to take a more active response to infection prevention, such as fundamentally removing the infectious agents contained in the air. .

1 is a schematic diagram illustrating a low-pressure blowing function and a high-pressure multi-stage compressed breathing air blower and charger having a combined air sterilization and purification function of a high temperature, high pressure, UV lamp according to an embodiment of the present invention.

As shown in Figure 1, the low-pressure blowing function and high-pressure multi-stage compressed breathing air blower and charger having a combined air sterilization and purification function of the high-temperature, high-pressure, UV lamp is a multi-stage air compressor as a means for compressing air to a high pressure. (12).

The multi-stage air compressor 12 serves to compress air in several stages while being driven by one power.

The multi-stage air compressor 12 may be configured in multiple stages, such as 2 to 6 stages, depending on the pressure required at the place of use, and in the present invention, the multistage air compressor 12 composed of three stages is the subject of the invention .

To this end, the multi-stage air compressor 12 includes a plurality of compression units 10 arranged in three directions of the compressor body 34, for example, a T-shaped, V-shaped, or W-shaped cylinder arrangement arranged at intervals of 90°. It can have a shape, and the T-type may include a first-stage compression part 10a, a second-stage compression part 10b, and a three-stage compression part 10c, as shown.

In a preferred embodiment, the first-stage compression section 10a, the second-stage compression section 10b, and the third-stage compression section 10c are approximately 90° along the circumference with the driving disk 35 disposed in the center as the center. may be spaced apart.

The first-stage compression part 10a, the second-stage compression part 10b, and the third-stage compression part 10c have a first-stage piston 36, a second-stage piston 37 and a third-stage piston (36) that compress air while reciprocating. 38) is provided, and each of the

pistons

36, 37, and 38 at this time are connected together with a phase difference to one driving disk 35 through a rod.

Accordingly, when the driving disk 35 is rotated by receiving power from a driving source such as a motor (not shown), the first-stage piston 36 to the third-stage piston 38 are respectively compressed by the

compression parts

10a, 10b, and 10c. It reciprocates within, and eventually, the air is sucked in by the sequential reciprocation of these pistons and then it can be discharged in a compressed state.

In addition, each of the

compression portions

10a, 10b, and 10c is formed with an inlet and an outlet each having a respective poppet valve 39, and each of the inlet and outlet is formed on the suction side of each of the

compression portions

For example, the inlet and outlet of the first-stage compression unit 10a are respectively connected to a suction-side line extending from the air intake device 11 and a connection line extending toward the second-stage compression unit 10b, and the two-stage compression The inlet and outlet of the part 10b are respectively connected to a connection line extending from the side of the first-stage compression unit 10a and a connection line extending from the side of the third-stage compression unit 10c, and the inlet and the outlet of the three-stage compression unit 10c The discharge port is respectively connected to a connection line extending from the side of the two-stage compression unit 10b and a discharge side line.

Accordingly, the external air is discharged from the air intake device 11 → the suction side line → the first stage compression section (10a) → the connecting line → the second stage compression section (10b) → the connecting line → the third stage compression section (10c) → the discharge side line is shown, and eventually, the external air provided from the air suction device 11 can be compressed in multiple stages while sequentially passing through each of the

compression units

10a, 10b, and 10c.

In particular, the

compression units

10a, 10b, and 10c of each stage of the multi-stage compression compressor 12 can compress air with a relatively large pressure as the stage increases.

For example, the first-stage compression unit 10a may have a compression capacity of 0 bar or more and less than 5 bar, the second-stage compression unit 10b may have a compression capacity of 5 bar or more and less than 50 bar, and the three-stage compression unit ( 10c) may have a compression capacity of 50 bar or more and less than 300 bar.

Here, the compression capacity of each compression unit may be appropriately set in consideration of the volume of the compression chamber, the diameter of the piston, and the like.

Accordingly, the air entering the first stage compression unit (10a) can be sent to the second stage compression unit (10b) after the first stage pressure is raised to about 5 bar, and the air entering the second stage compression unit (10b) is 5 bar or more and less than 50 bar After being pressurized in two stages, it can be sent to the third stage compression unit (10c), and the air entering the third stage compression unit (10c) can be sent to the final destination after being pressurized in three stages to 50 bar or more and less than 300 bar.

Usually viruses and bacteria die at a temperature of 60° C. or higher, and at a pressure of 10 bar or higher.

Accordingly, during the compression process of each of the

compression units

10a, 10b, and 10c, the air is pressurized by one stage through the first stage compression unit 10a, and then passes through the second stage compression unit 10b in two stages to 5 bar or more and less than 50 bar. During the pressurization, bacteria such as viruses and bacteria contained in the air can be completely eradicated.

In addition, the low-pressure blowing function and the high-pressure multi-stage compressed breathing air blower and charger having a combined air sterilization and purification function of the high temperature, high pressure, and UV lamp are a plurality of means for separating and removing moisture and oil in the air generated during the air compression process. It includes a foreign object discharge device 13 .

For example, the foreign material discharging device 13 includes a connection line between the first-stage compression unit 10a and the second-stage compression unit 10b, and a connection between the second-stage compression unit 10b and the third-stage compression unit 10c. The line and the three-stage compression unit 10c may be respectively installed on the discharge-side line, and foreign substances generated in the compression process of the

respective compression units

10a, 10b, and 10c may be removed.

In particular, in addition to the role of removing foreign substances (moisture, oil, etc.) in the air during the compression process, the foreign material discharge device 13 serves to prevent viruses and bacteria from being discharged into the atmosphere, a detailed description thereof will be described later. decide to do

In addition, the low-pressure blowing function and the high-pressure multi-stage compressed breathing air blower and charger having a combined air sterilization and purification function of the high temperature, high pressure, and UV lamp are air filter devices (14) includes

The air filter device 14 is installed on the discharge side line of the compression unit 10 located at the end of the multi-stage air compressor 12, that is, on the discharge side line extending from the three-stage compression unit 10c, It plays a role in purifying the compressed air supplied to the place of use.

As the air filter device 14 is installed on the discharge-side line extending from the three-stage compression unit 10c in this way, foreign substances contained in the high-pressure compressed air can be supplied to the place of use in a state in which they are finally removed.

The air filter device 14 has a structure including a desiccant (not shown) and activated carbon (not shown) for removing moisture, odors, and harmful gases such as carbon monoxide and carbon dioxide in compressed air, and uses an adsorption principle to remove compressed air. It is possible to effectively remove foreign substances, etc. from the inside.

The compressed air purified through the air filter device 14 is sent to the place of use along the discharge side line, and foreign substances filtered through the air filter device 14 pass through the drain 40 of the air filter device 14 to the outside. It is collected after being discharged to the

In addition, the low-pressure blowing function and the high-pressure multi-stage compressed breathing air blower and charger having a combined air sterilization and purification function of the high temperature, high pressure, and UV lamp are a means for sensing the temperature and pressure of the compressed air, the temperature sensor 17 and the pressure It includes a sensor 18 .

The temperature sensor 17 and the pressure sensor 18 may consist of at least one installed on the connection line and the discharge side line of each compression unit 10 .

As an example, the temperature sensor 17 includes one on the connection line between the first-stage compression unit 10a and the second-stage compression unit 10b, the second-stage compression unit 10b and the third-stage compression unit 10c. A total of three, such as one on the connection line and one on the discharge side line of the three-stage compression unit 10c, can be provided, and the pressure sensor 18 also includes a first-stage compression unit 10a and a two-stage compression unit. One on the connecting line of (10b), one on the connecting line of the two-stage compression unit 10b and the three-stage compression unit 10c, one on the discharge side line of the three-stage compression unit 10c, etc. total Three can be provided.

The temperature and pressure values sensed by the temperature sensor 17 and the pressure sensor 18 are low-pressure blowing function and high-pressure multi-stage compressed breathing air with a combined air sterilization and purification function of the high temperature, high pressure, and UV lamp of the present invention. And it is input to a controller (not shown) that manages the operation of the charger so that it can be used to control the operation of the solenoid valves.

In addition, the low-pressure blowing function and the high-pressure multi-stage compressed breathing air blower and charger having a complex air sterilization and purification function of the high temperature, high pressure, and UV lamp selectively control the supply and discharge of air compressed by the compression unit 10 . It includes a first solenoid valve 15 and a second solenoid valve 16 as a means to do so.

The first solenoid valve 15 and the second solenoid valve 16 allow compressed air that meets predetermined conditions, for example, compressed air from which viruses and bacteria have been removed, to be supplied to a place of use, and viruses and bacteria are not removed. The uncompressed air is discharged to the outside.

To this end, the first solenoid valve 15 and the second solenoid valve 16 are sequentially connected to the discharge side line of the compression unit 10 positioned at the end of the multi-stage air compressor 12 , that is, the three-stage compression unit 10c. It can be installed to selectively exhaust compressed air.

Preferably, the second solenoid valve 16 can be installed on the drain 40 side of the air filter device 14 .

The first solenoid valve 15 and the second solenoid valve 16 are selectively ON (open) operation or OFF (closed) operation by receiving output control by a controller (not shown).

For example, the temperature sensed by the temperature sensor 17 is 50 to 70° C. or less, preferably 60° C. or less, and/or the pressure sensed by the pressure sensor 18 is 8 to 12 bar or less, preferably 10 bar. Below, the detection signal at this time is input to the controller, and at the same time, the first solenoid valve 15 is closed and the second solenoid valve 16 is opened by the output control of the controller, so the compressed air at this time is not provided to the place of use. and is emitted to the outside as it is.

In other words, since viruses and bacteria die at a temperature of 60 °C or higher and at a pressure of 10 bar or higher, when the compressed air temperature is 60 °C or lower or the compressed air pressure is 10 bar or lower, bacteria such as viruses and bacteria are included in the compressed air. Since it is reasonable to assume that there is, it is desirable to discharge the compressed air at this time to the outside.

Conversely, the temperature sensed by the temperature sensor 17 is greater than 50 to 70° C., preferably greater than 60° C. and/or the pressure sensed by the pressure sensor 18 is greater than 8 to 12 bar, preferably greater than 10 bar. In this case, the detection signal at this time is input to the controller, and at the same time, the second solenoid valve 16 is closed and the first solenoid valve 15 is opened by the output control of the controller, so that the compressed air at this time, that is, viruses and bacteria The compressed air that has been cleaned and sterilized can be sent to the place of use.

Accordingly, the primary LED UV lamp 24a sterilizes bacteria such as viruses and bacteria in the air when the air flows from the outer side of the case, and the secondary LED UV lamp 24b is installed in the air flowing through the inside of the partition wall. There is a double effect of sterilizing bacteria such as viruses and bacteria while simultaneously sterilizing bacteria such as viruses and bacteria accumulated on the surface of the micro filter 23a.

Therefore, there is no need to coat a silver nano material or the like to sterilize the bacteria accumulated on the outer surface of the filter non-woven fabric as in the past, and the filter itself is also sterilized through the bar-type UV lamp 24c located inside the micro filter 23a. It has the effect of

To this end, the drain core 30 is installed in a structure that is erected side by side along the inner central axis of the discharge device case 25, and at the same time, moisture or oil is separated from the upper part by using the separation plate 27 of the upper part in the form of a disk. It prevents splashing toward the micro filter (23b) of the.

In addition, the drain core 30 uses a plurality of holes 28 and hollow inner passages 29 formed in the core body in the form of a hollow pipe to fill the bottom of the discharge device case 25 . and moisture can be expelled.

At this time, a timer-type solenoid valve (not shown) is attached to the drain side of the foreign material discharging device 13 , for example, at the lower end of the drain core 30 , so that the foreign material can be periodically and automatically discharged.

When the moisture and oil discharged during this discharge process contain viruses or bacteria, a plurality of bar-type UV lamps 26b are installed at the bottom of the inside of the discharge device case 25 to sterilize the moisture and oil to be discharged. The included bacteria can be sterilized, and at the same time, to sterilize the air discharged to the outside of the device, it passes through the flow path of the diaphragm structure and is discharged through the filter layer, and a plurality of primary LED UV lamps in the space to which the filter layer belongs. (26a) is installed so that bacteria contained in the discharged air can be sterilized.

Here, at the time of discharge, the compressed air at high pressure is compressed at once, so a method of discharging in a 2WAY top/bottom method can be applied to reduce the pressure, reduce noise, and reduce the discharge speed during discharge. Moisture and oil lumps, which are liquids that are discharged and contained in the air, rotate within the case when discharged (rotating by the swirling force of air introduced through the air inlet 19b formed in the tangential direction of the outer circumferential surface of the case) inside the case It can flow down and gather.

In a system that uses a piston-type multi-stage compression structure such as three or four stages for a high pressure increase of 200 to 300 bar for charging the air respirator of the CBC, firefighting, and quarantine authorities, which must be used by compressing air at high pressure, multistage air A temperature sensor 17 is provided at each compression stage 10a to 10c of the compressor 12 to monitor whether the temperature of the air has reached a temperature of 60° C. or higher, which is a temperature at which bacteria such as viruses and bacteria die, and, along with each A pressure sensor 18 is provided at the compression ends 10a to 10c to monitor whether the pressure of the air reaches a pressure of 10 bar or more, which is the pressure at which bacteria such as viruses and bacteria die, so that viruses and bacteria contained in the compressed air, etc. It is possible to supply cleanly purified and sterilized compressed air to the place of use while completely eradicating the bacteria of

For example, when the temperature of the air does not exceed 60 °C during the compression process, or when the air pressure does not exceed 10 bar, or when the air temperature does not exceed 60 °C and the pressure does not exceed 10 bar, The first solenoid valve 15 is operated OFF and the second solenoid valve 16 is operated ON to discharge air to the outside during the compression process.

And, when the temperature of the air during the compression process is 60° C. or higher, or when the air pressure is 10 bar or higher, or when the air temperature is 60° C. or higher and the pressure is 10 bar or higher, the first solenoid valve 15 operates ON and The two solenoid valve 16 operates OFF to supply air to the place of use during the compression process, while adsorbing fine dust, moisture, oil, and harmful gases such as carbon monoxide and carbon dioxide in the air sent to the final air filter device 14 by zeolite material. It is purified through a filter non-woven fabric, and odors in the air are removed by using an adsorption type filter made of activated carbon material. sterilized air can be produced.

4 is a schematic diagram showing a low-pressure blowing function and a high-pressure multi-stage compressed breathing air blower and charger having a complex air sterilization and purification function of a high temperature, high pressure, UV lamp according to another embodiment of the present invention.

As shown in FIG. 4 , here is an example of a low-pressure air blower that discharges low-pressure air during the compression process and uses it for other purposes (eg, use as sterilizing air in a negative pressure room of a hospital, etc.).

To this end, a bypass pipe 31 is connected and installed between the suction-side line and the discharge-side line of the compression unit 10 positioned at the end of the multi-stage air compressor 12, that is, the 3-stage compression unit 10c. Accordingly, the compressed air coming out of the two-stage compression unit 10b enters the three-stage compression unit 10c and is compressed or can be bypassed without entering the three-stage compression unit 10c.

In addition, the third solenoid valve 32 is installed on the suction side line of the compression unit 10 positioned at the end of the multi-stage air compressor 12, that is, the three-stage compression unit 10c, and the bypass pipe 31 The front end of the, for example, a connection line connected to the suction side of the front end of the bypass pipe 31 branching off on the connection line connected to the suction side of the three-stage compression section (10c) or the three-stage compression section (10c) A fourth solenoid valve 33 is installed at the front end of the bypass pipe 31 extending from the drain side of the foreign material discharging device 13 installed thereon.

Here, the third solenoid valve 32 and the fourth solenoid valve 33 are controlled by a controller to selectively regulate the flow of compressed air while being operated ON/OFF.

Therefore, when the user selects low pressure air supply, the third solenoid valve 32 is closed and the fourth solenoid valve 33 is opened at the same time, and the compressed air (air compressed at low pressure) coming out of the two-stage compression unit 10b at this time is After being bypassed through the bypass pipe 31 without going through the three-stage compression unit 10c and sent to the compressed air discharge line, it is continuously supplied to the place of use, and eventually low-pressure compressed air (10 bar or more and less than 50 bar) is used in the negative pressure room of the hospital. It can be supplied and used.

And, when the user selects high-pressure air supply, the third solenoid valve 32 is opened and the fourth solenoid valve 33 is closed, and the compressed air coming out of the second-stage compression unit 10b is continuously transferred to the three-stage compression unit ( 10c), and eventually 30Mpa of high-pressure air used for respirator, etc. can be supplied to the place of use.

In this way, a separate low-pressure filter line is constructed for sterilized air with a low pressure of 10 bar or more and less than 50 bar during the compression process to remove moisture and oil, fine dust, and odors, which are foreign substances in the air, with a non-woven fabric filter, By passing it through a purifying filter and discharging it, it can be supplied to a negative pressure room of a hospital, etc., and can be effectively used for treatment of COVID-19.

To this end, when the low-pressure sterilization mode is set in the controller, the third solenoid valve 32 and the fourth solenoid valve 33 are used after the multi-stage treatment process, the main two-stage compression (5-50 bar compression process), and the next three stages 100% of the line going to compression (50-300 bar compression process) is blocked, and the function of sending air to the bypass pipe 31 can be secured.

As another example, the third solenoid valve 32 and the fourth solenoid valve 32 and the fourth solenoid valve 32 and the fourth solenoid to simultaneously implement two functions, that is, work and quarantine, that is, a function for a user to fill a high-pressure air of 300 bar by a low-pressure sending function and a high-pressure compression. 50% of the operation of the valve 33 is sent to the low-pressure air blower through appropriate control, and 50% goes to the next compression stage (three-stage compression unit), and finally passes through the high-pressure compression stage to the air respirator while having a pressure of 300 bar. Virus sterilization and purified air can be filled.

As described above, in the present invention, by providing a system for compressing air at high pressure through the high-pressure compression function of the multi-stage air compressor, the irradiation function of the UV lamp, and the filtration function of the micro filter, after killing viruses and bacteria contained in the air It is possible to supply clean, sterilized air to the place of use, and adopts a method that appropriately controls the multi-stage compression process during air compression. % By providing a new system that selectively performs low-pressure air, it is possible to supply purified and sterilized compressed air suitable for various uses such as negative pressure rooms in hospitals, quarantine, and air respirator.
