Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

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

As shown in Fig. 1, the high-temperature, high-pressure, low-pressure blowing function and high-pressure multi-stage compressed breathing air blower and charger having a complex air sterilization and purification function of a UV lamp are multi-stage air compressors as means for compressing air at 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 composed of several stages, such as two to six stages, depending on the pressure required at the place of use, and in the present invention, the multi-stage air compressor 12 composed of three stages is the object of its design. .

To this end, the multi-stage air compressor 12 has a plurality of compression parts 10 arranged in three directions of the compressor body 34, for example, a T-type, V-type or W-type cylinder disposed at 90° intervals. It may have a shape, and in the T-type, as illustrated, a first stage compression unit 10a, a second stage compression unit 10b, and a third stage compression unit 10c may be included.

As a preferred embodiment, the first stage compression unit 10a, the second stage compression unit 10b, and the third stage compression unit 10c are centered around a driving disk 35 disposed in the center and approximately 90° along its circumference. It can be arranged at intervals.

The first-stage compression section 10a, the second-stage compression section 10b, and the third-stage compression section 10c include a first-stage piston 36, a second-stage piston 37, and a third-stage piston that compress air while reciprocating. 38) are respectively provided, and each piston 36, 37, and 38 is connected together while having 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 parts 10a, 10b, and 10c. In the reciprocating motion within, eventually the air can be sucked out and discharged in a compressed state by the sequential reciprocating motion of these pistons.

In addition, inlet and outlet ports having respective poppet valves 39 are formed in the respective compression units 10a, 10b, and 10c, and each of the inlet and outlet ports is a suction side of each of the compression units 10a, 10b, and 10c. It is connected to the line and the discharge-side line, respectively.

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 two stage compression. The inlet and outlet of the portion 10b are respectively connected to a connecting line extending from the first stage compression unit 10a side and a connecting line extending to the third stage compression unit 10c side, respectively, and a suction port of the third stage compression unit 10c. The outlets are respectively connected to a connection line and a discharge line extending from the two-stage compression section 10b side.

Accordingly, the outside air is an air intake device 11 → suction side line → 1 stage compression unit 10a → connection line → 2 stage compression unit 10b → connection line → 3 stage compression unit 10c → discharge side line The flow through the air is shown, and in the end, the external air provided from the air intake device 11 can be compressed in multiple stages sequentially 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 type compressor 12 can compress air at a relatively large pressure as the stage is higher.

For example, the first stage compression unit 10a may have a compression capacity of 0 bar or more and less than 5 bar, and the second stage compression unit 10b may have a compression capacity of 5 bar or more and less than 50 bar, and a third 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 can be appropriately set in consideration of the compression chamber volume, piston diameter, and the like.

Accordingly, the air entering the first stage compression unit 10a can be sent to the second stage compression unit 10b after being boosted by one stage 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 boosted by the second stage, 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 use after being boosted by three stages to 50bar or more and less than 300bar.

Viruses and bacteria usually die at temperatures above 60°C and at pressures above 10 bar.

Therefore, during the compression process of each of the compression units 10a, 10b, and 10c, the air is boosted by one stage through the first compression unit 10a, and then through the second compression unit 10b to 5 bar or more and less than 50 bar. During the boosting, bacteria, such as viruses and bacteria, contained in the air can be completely eradicated.

In addition, the high-temperature, high-pressure, low-pressure blowing function and high-pressure multi-stage compressed breathing air blower and charger having a complex air sterilization and purification function of the 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 dog foreign matter discharge method (13).

The foreign substance discharge device 13 is installed on the connection line and the discharge side line between each compression unit 10 of the multi-stage air compressor 12, and serves to separate and remove moisture and oil contained in the air.

For example, the foreign substance discharge device 13 is a connection line between the first-stage compression section 10a and the second-stage compression section 10b, and the connection between the second-stage compression section 10b and the third-stage compression section 10c. Lines, respectively, can be installed on the discharge-side lines of the three-stage compression section 10c, and it is possible to remove foreign substances generated during the compression process of each compression section 10a, 10b, 10c.

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

In addition, the high-temperature, high-pressure, 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 UV lamp are air filter devices 14 as a means for purifying compressed air that is finally supplied to the place of use. It includes.

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

In this way, the air filter device 14 is installed on the discharge-side line extending from the three-stage compression section 10c, so that foreign matters and the like contained in the compressed air at high pressure can be supplied to the user in the final removed state.

The air filter device 14 is a structure including a dehumidifying agent (not shown) and activated carbon (not shown) for removing carbon monoxide and carbon dioxide, which are moisture and odor and harmful gases in compressed air, and uses compressed air to absorb compressed air. It is possible to effectively remove foreign substances and the like from the inside.

Compressed air purified through the air filter device 14 is sent to a user along the discharge side line, and foreign matter filtered through the air filter device 14 is external through the drain 40 of the air filter device 14. After being discharged, it is collected.

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

The temperature sensor 17 and the pressure sensor 18 may be made 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 is a single, two-stage compression unit (10b) and three-stage compression unit (10c) on the connection line of the first stage compression unit (10a) and the second stage compression unit (10b) A total of three can be provided, such as one on the connection line, one on the discharge side line of the three-stage compression section 10c, and the pressure sensor 18 also has one-stage compression section 10a and two-stage compression section. One on the connecting line of (10b), one on the connecting line of the two-stage compression section (10b) and three-stage compression section (10c), one on the discharge side line of the three-stage compression section (10c), etc. Three can be provided.

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

In addition, the high-temperature, high-pressure, low-pressure blowing function and the high-pressure multi-stage compressed breathing air transmitter and charger with a complex air sterilization and purification function of the 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).

The first solenoid valve (15) and the second solenoid valve (16) allow compressed air having 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. Uncompressed air plays a role to be discharged to the outside.

To this end, the first solenoid valve 15 and the second solenoid valve 16 are sequentially on the discharge side line of the compression section 10, that is, the three-stage compression section 10c, located at the end of the multistage air compressor 12. It is installed to be able to selectively discharge compressed air.

Here, the first solenoid valve 15 can be installed at the rear end of the air filter device 14 installed on the discharge side line extending from the three-stage compression unit 10c, and the second solenoid valve ( 16) can be installed in the front end of the air filter device (14).

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 turned on (open) or turned off (closed) under output control by a controller (not shown).

For example, the temperature detected 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. In the following case, 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. It is released as it is without.

In other words, viruses and bacteria are killed at a temperature of 60°C or higher and are killed at a pressure of 10 bar or higher, so if the temperature of compressed air is 60°C or lower or the pressure of compressed air is 10bar or lower, bacteria such as viruses and bacteria are included in the compressed air. It is advisable to assume that it is preferable to release compressed air at this time.

On the contrary, the temperature detected 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. If this is the 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. Is killed and clean sterilized compressed air can be sent to the place of use.

To this end, the drain core 30 is installed in a structure erected side by side along the inner central axis of the discharge device case 25, and at the same time, water or oil is used upward by using the separation plate 27 in the upper portion in the form of a disc. It prevents splashing toward the micro filter 23b.

In addition, the drain core 30 is filled in the bottom side of the discharge device case 25 by using a plurality of holes 28 and a hollow inner passage 29 formed in a core body formed of a hollow pipe shape. And the moisture can be discharged.

At this time, a timer-type solenoid valve (not shown) is attached to the drain side of the foreign substance discharge device 13, for example, at the lower end of the drain core 30 to periodically and automatically discharge foreign substances.

When a virus or bacteria are contained in the water and oil discharged during the discharge process, a plurality of bar type UV lamps 26b are installed under the inside of the discharge device case 25 to disinfect the water and oil discharged. The included bacteria can be sterilized, and at the same time, through the passage of the diaphragm structure and through the filter layer for the sterilization of the air discharged to the outside of the device, a number of primary LED UV lamps are included in the space where the filter layer belongs. (26a) is installed so that the bacteria contained in the exhaust air can be sterilized.

Here, since the compressed air at high pressure is compressed at the same time during discharge, it is possible to apply the 2WAY up/down method for controlling to reduce pressure, reduce noise, and reduce the discharge speed during discharge. Inside the case, the water and oily substances that are discharged and contained in the air are rotated in the case when discharged (rotating by the turning force of the air flowing through the air inlet 19b formed in a tangential direction of the case outer circumference). It can flow down and gather.

In this system, a three-stage or four-stage piston type multistage compression structure is applied to increase the high pressure pressure of 200~300bar to charge air respirators of firefighting, firefighting, and quarantine authorities that need to compress and use air at high pressure. Each compression stage (10a ~ 10c) of the compressor (12) is provided with a temperature sensor (17) to monitor whether the temperature of the air has reached a temperature of 60°C or higher, which is the temperature at which bacteria such as viruses and bacteria die. By providing a pressure sensor 18 in the compression stages 10a to 10c, monitoring whether the pressure of air reaches a pressure of 10 bar or more, which is the pressure at which bacteria such as viruses and bacteria die, viruses and bacteria contained in compressed air, etc. It is possible to supply cleanly purified and sterilized compressed air to the place of use with completely eradicated bacteria.

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

And, if the temperature of the air during the compression process is 60 ℃ or more, or the pressure of the air is more than 10bar, or the temperature of the air is more than 60 ℃ and the pressure is more than 10bar, the first solenoid valve 15 is turned ON and 2 The solenoid valve (16) operates OFF to supply air to the user during the compression process, while adsorbing fine dust, moisture and oil, harmful gases such as carbon monoxide and carbon dioxide in the air sent to the final air filter unit (14) The filter is purified through a non-woven fabric, and the odor in the air is activated by using an adsorption filter made of activated carbon. Afterwards, viruses in the air that may be left are finally purified through a micro-micron (0.01 to 0.1 µm) filter, then discharged and fresh. It is possible to produce sterilized air.

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

As shown in FIG. 4, here, an example of a low pressure air blower used for discharging low pressure air during compression is used for other purposes (for example, as a sterilized air in a negative pressure room of a hospital).

To this end, a bypass pipe 31 is installed between the suction side line and the discharge side line of the compression section 10, that is, the compression section 10, which is positioned at the end of the multistage air compressor 12, and thus Accordingly, the compressed air coming from the second-stage compression section 10b can be compressed by entering the third-stage compression section 10c or bypassing the third-stage compression section 10c.

In addition, a third solenoid valve 32 is installed on the suction side line of the compression section 10, that is, the three-stage compression section 10c, located at the end of the multistage air compressor 12, and the bypass pipe 31 The front end of, for example, the connecting line connected to the suction end of the bypass pipe 31 or the front end of the bypass pipe 31 branched on the connecting line connected to the suction side of 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 substance discharge device 13 installed on the top.

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

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

In addition, when the user selects the high pressure air supply, the third solenoid valve 32 is opened and the fourth solenoid valve 33 is closed, and the compressed air from the two-stage compression unit 10b continues to be a three-stage compression unit ( 10c), and eventually, 30Mpa of high pressure air used in an air respirator can be supplied to the user for use.

As such, a separate low-pressure filter line is established for the sterilized air of 10 bar or more and less than 50 bar, which is a low-pressure step during the compression process, to remove foreign substances such as moisture, oil, and fine dust and odor through a non-woven filter, and to 0.01 μm. By passing through a purifiable filter and discharging it, it is supplied to a sound pressure room of a hospital, and thus it can be effectively used for the treatment of corona 19 and the like.

To this end, if a low pressure sterilization mode is set on the controller, the next three stages are utilized by using the third solenoid valve 32 and the fourth solenoid valve 33 after the multistage treatment process, the second stage compression (5-50 bar compression process) treatment process. The line going to compression (50~300bar compression process) is 100% 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 electron to simultaneously implement the function of filling the air of a high pressure with a bar of 300 bar, such as a low pressure air supply function and a high pressure compression, that is, a function that requires work and prevention. Through proper control of the operation of the valve 33, 50% is sent to a low-pressure air blower, and 50% is directed to the next compression stage (three-stage compression section). Virus sterilization and purified air can be charged.

As described above, the present invention provides a system for compressing air at a high pressure through a high pressure compression function of a multi-stage air compressor, an irradiation function of a UV lamp, and a filtration function of a micro filter, thereby killing viruses and bacteria contained in the air. 100% high pressure air, 100% low pressure air, 1~99% high pressure air, and 99~1 by adopting a method that can supply clean and sterilized air to the place of use and properly control the multi-stage compression process during air compression. % By providing a new system that selectively performs low-pressure air transmission, it is possible to supply compressed air that has been purified and sterilized for a variety of uses, such as a sound pressure room in a hospital, in case of discharge, and an air respirator.
