Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an oxygen and nitrogen concentration adjustable high pressure air charger,

The present invention relates to an oxygen and nitrogen concentration-regulated high-pressure air charger with aroma generating means, and more particularly to firefighters, water sports and work workers, general industry or people in need of breathing air for medical purposes The present invention relates to an oxygen and nitrogen concentration-regulated high-pressure air charger having a supply port for automatically regulating the oxygen and nitrogen concentration and a perfume generating means for supplying the air containing the perfume.

In general, firefighters who perform rescue work in case of fire, people who enjoy underwater sports or work underwater, people who need breathing air for medical purpose, etc., use air tank filled with respiratory air for breathing .

These respiratory air tanks will be filled with new breathing air if the remaining volume is reduced after use. If left unused for about 3 to 4 months even if not in use, the air in the tank will be prevented from being contaminated After discharging the residual internal air, the new breathing air is charged and used.

As an example of a means for filling the present breathing air tank with fresh breathing air, there is an air compressor which compresses and supplies only general air (general air of about 20% oxygen and about 80% nitrogen) to high pressure.

As another example, there are products in which oxygen and nitrogen are separately contained in a liquid state and circulated on the market.

Generally, in the case of breathing air or industrial air, it is necessary to separate oxygen and nitrogen depending on the intended use, such as for aquatic sports, medical use, and general industrial use. In addition, the concentration of oxygen or nitrogen is suitably adjusted There is a need.

For example, Korean Patent Registration No. 10-0928589 discloses a " mixed gas separation and supply apparatus " in which two or more gases are mixed into a gas component from a mixed gas.

However, the " mixed gas separation / supply device " has disadvantages in terms of energy and spatial layout, since it is a method of operating two compressors operating with separate driving forces separately.

In the case of the method of adjusting the concentration of oxygen or nitrogen, the accuracy of the concentration control is lowered due to the method of manually proceeding with the ratio using current 100% purity oxygen for medical use or 100% purity nitrogen for industrial use. Not only in terms of efficiency, but also in terms of adjusting the optimum concentration suitable for various fields, environments, and various conditions.

On the other hand, the air that is the object of respiration for humans is very important, and the smell contained in the air, that is, the aroma has an absolute influence on the other organs or sensibility of the human body through the smell of the person. This provides the advantage.

For example, clean air and good fragrance can basically enrich the mind, and it is possible to improve the efficiency of various works such as relieving stress by alleviating tensions or diversion.

In addition, good fragrance can remove other odors, and sanitary air can be provided by the sterilizing power contained in the fragrance.

In the case of indoor air conditioning, it is installed in a state in which fragrance is exposed while the air passing through the air duct is directly exposed, and mixed with the fragrance and the spray gas in the compressed vessel, and then the spray gas pressure is used And sprayed in a spraying manner.

The present invention is directed to a technique of supplying oxygen or nitrogen having an optimum concentration suitable for various fields and environments, various conditions and the like, as well as a mixture of aromas beneficial to the human body, while controlling the concentration of oxygen or nitrogen .

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

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram showing the overall layout of an oxygen and nitrogen concentration controlled high pressure air charger with aroma generating means according to an embodiment of the invention; FIG.

As shown in FIG. 1, the oxygen and nitrogen concentration-regulated high-pressure air charger equipped with the above-described perfume generating means can appropriately adjust the oxygen or nitrogen concentration in the atmosphere within a range of 20 to 90 vol% , And in particular, the structure and the layout of the entire system are optimized through a proper combination of arrangement of the multi-stage compression type compressor and each line.

For this purpose, the oxygen and nitrogen concentration-regulated high-pressure air charger includes an integral multi-stage compression compressor 12 as a means for compressing air in a multistage manner while being driven by a single power.

Generally, multi-stage compressors can be composed of more than 2 units as the pressure to be used is higher, 200 or 300 bar is 3 or 4, 400 ~ 700 bar is 5, and more than 700 bar is 6 or more.

For example, when the multi-stage compression type compressor 12 is constructed in a three-stage multi-stage type, a plurality of compression portions arranged in three directions of the compressor main body 31, for example, T- V-shaped or W-shaped cylinder arrangement shape. As shown in the T-shape, the first-stage compressing section 10a, the second-stage compressing section 10b and the third-stage compressing section 10c can be included .

In the preferred embodiment, the first stage compressing section 10a, the second stage compressing section 10b and the third stage compressing section 10c are formed by centering the drive disc 30 (or centering one power transmission section of the crankshaft) ) Can be disposed at intervals of about 90 DEG around the circumference thereof.

The first stage compression section 10a, the second stage compression section 10b and the third stage compression section 10c are provided with a first stage piston 23, a second stage piston 24 and a third stage piston 25, respectively. The pistons 23, 24, 25 at this time are connected together with a phase difference to one driving disc 30 through a rod.

Accordingly, when the driving disk 30 is rotated by receiving power from a driving source such as a motor (not shown), the pistons 23, 24, and 25 are reciprocated in the respective compressing portions 10a, 10b, So that the piston can be discharged in a compressed state after the air is sucked by the sequential reciprocating motion of the pistons.

Each of the compressing portions 10a, 10b, and 10c is provided with a suction port and a discharge port each having a poppet valve 28. Each of the suction port and the discharge port is connected to an atmospheric side line, a discharge and suction side line, a final discharge side line Respectively.

For example, the suction port and the discharge port of the first-stage compressing section 10a are respectively connected to the main standby line 11 and the discharge / suction line 13a, and the suction port and the discharge port of the second- The suction port and the discharge port of the third stage compressing section 10c are connected to the discharge / suction line 13b and the discharge line 15, respectively.

Accordingly, the air is discharged from the main waiting line 11 → the first stage compression section 10a → the discharge / suction line 13a → the second stage compression section 10b → the discharge / suction line 13b → the third stage compression section 10c The external air flowing through the main waiting line 11 can be compressed in multiple stages while sequentially passing through the respective compression units 10a, 10b and 10c.

Here, the main waiting line 11 can be provided with a dust removing filter 29a, which functions to remove dust and foreign substances in the air introduced into the compressor.

In particular, as the stages of the compression units 10a, 10b, and 10c at the respective stages of the multi-stage compression type compressor 12 become higher, a relatively larger compression pressure can be used.

For example, in the case of a three-stage compression structure, the first-stage compressing section 10a may have a compression capacity of not less than 0 bar and less than 10 bar, and the second-stage compressing section 10b may have a compression capacity of not less than 10 bar and less than 50 bar And the third stage compressing section 10c can have a compression capacity of 60 bar or more.

For reference, in the case of a four-stage compression structure, the pressure of each compression stage is set to be 0 to 5 bar for the first stage compression, 5 to 20 bar for the second stage compression stage, 20 to 100 bar for the third stage compression stage, Can be compressed.

Here, the compression capacity of each compression section can be appropriately set in consideration of the actual compression volume, the piston diameter, and the like.

 Accordingly, the air introduced into the first-stage compressing section 10a can be sent to the second-stage compressing section 10b after being raised from 5 bar to less than 50 bar by one step, and air introduced into the second- Stage compressing section 10c after the two-stage boosting to less than 100 bar, and the air introduced into the third-stage compressing section 10c can be sent to the end-use place after the three-stage boosting to 100 bar or more.

As described above, in the case of the multi-stage compression type compressor 12, the compression portions 10a, 10b, and 10c are arranged in three directions in the compressor main body 31, and in addition to the oxygen and nitrogen separators 14 The main standby line 11, the discharge / suction lines 13a and 13b and the discharge line 15 are arranged around the compressor main body 31 and properly connected to the respective compressing portions 10a, 10b and 10c So that it is possible to efficiently design the entire facility layout, such as minimizing the space occupancy and scale.

In addition, the oxygen and nitrogen concentration-regulated high-pressure air charger equipped with the above-described perfume generating means additionally incorporates the atmosphere to control the concentration of oxygen or nitrogen, and also provides pure air of about 20 vol% A bypass pipe 19 is provided between the first-stage compressing section 10a and the second-stage compressing section 10b so as not to pass the oxygen and nitrogen separator 14 if necessary.

 Here, in order to control the oxygen or nitrogen concentration of the gas to be finally compressed, the sub waiting line 17 is connected to the discharge / suction line 13a connected between the first stage compression section 10a and the second stage compression section 10b do.

That is, the sub stand-by line 17 is connected to the oxygen discharge line 18b extending in the oxygen and nitrogen separator 14 and the discharge / suction line 13a, which is the rear end side merging line of the nitrogen discharge line 18a .

The sub-waiting line 17 can be provided with a dust removing filter 29b, which functions to remove dust and foreign substances in the air introduced into the compressor.

Accordingly, the air having the oxygen concentration of about 20 vol.% Flowing through the bypass pipe 19 from the first-stage compressing section 10a is supplied to the second-stage compressing section 10b Air of about 20 vol.% Flowing in through the sub-waiting line 17 is mixed with oxygen or nitrogen discharged from the oxygen and nitrogen separator 14 at a predetermined ratio, And then enters the compression section 10b.

As described above, the sub-standby line 17 is connected to the suction side of the second-stage compressing section 10b and can be appropriately utilized for adjusting the oxygen or nitrogen concentration to the air that is further introduced through the sub-standby line 17 , It is possible to broaden the performance and function of the high-pressure air charger such that it can broaden the range of choices required by the user or the user in relation to the concentration-controlled supply of oxygen or nitrogen.

Here, the bypass pipe 19 and the sub waiting line 17 are provided in the multi-stage compression type compressor 12, and these are operated together, which is advantageous in not only ensuring a sufficient compression volume of the compressor but also enhancing energy efficiency.

For example, in the case of supplying only the atmosphere of about 20% by volume of the oxygen concentration, the atmosphere can be sucked through the first-stage compressing section 10a with a sufficient compression volume and supplied through the bypass pipe 19, It is possible to secure a desired air amount with respect to the operation efficiency.

Therefore, in the case of supplying only the atmosphere of about 20% by volume of the oxygen concentration, the bypass line 19 is used, and when the oxygen concentration and the atmosphere are supplied in a controlled manner, There is also an advantage in that sufficient energy can be secured and provided while reducing energy loss.

On the other hand, when only the atmosphere of about 20% by volume of the oxygen concentration is supplied by using the sub-standby line 17 without the bypass pipe 19, the atmosphere is supplied through the second-stage compressing unit 10b having a relatively small compression volume It is not possible to provide a sufficient amount of air as much as desired with respect to the operation efficiency of the compressor. In addition, since the first stage compressing section 10a is also in the idle state, it is inefficient in terms of energy loss.

In addition, the oxygen and nitrogen concentration regulated high pressure air charger with the perfume generating means substantially comprises oxygen and nitrogen separator 14 as a means of separating oxygen and nitrogen in the air.

The oxygen and nitrogen separator 14 is installed on the discharge / suction line 13a connecting between the first stage compression section 10a and the second stage compression section 10b of the multi-stage compression type compressor 12, And serves to separate oxygen and nitrogen in the air.

For example, the oxygen and nitrogen separator 14 is provided with a gas separation membrane (not shown) inside the separator case, and the gas-liquid separator inner channel (not shown) and the gas- Are connected to two independent lines, that is, a nitrogen discharge line 18a and an oxygen discharge line 18b, which extend out of the separator case.

Here, in the case of the oxygen and nitrogen separator 14, a PSA method or the like may be applied in addition to the membrane method.

The nitrogen discharge line 18a and the oxygen discharge line 18b merge together at the downstream end in the traveling direction and then are discharged to the discharge side of the discharge / Line 13a.

Accordingly, when the compressed air from the first-stage compressing section 10a flows into the inside of the oxygen and nitrogen separator 14 through the discharge / suction line 13a, the compressed air thus introduced flows through the gas- Nitrogen, respectively. That is, due to the difference in solubility and permeability between the respective gases depending on the difference in the partial pressures of oxygen and nitrogen, only oxygen in the two gases is selectively permeated and separated into oxygen and nitrogen, (18b), and nitrogen is discharged to the nitrogen discharge line (18a), respectively.

Here, the method of separating the mixed air into oxygen and nitrogen using the principle of the gas separation membrane is the same as that of the conventional art, so a detailed description thereof will be omitted.

The oxygen- and nitrogen-concentration-regulated high-pressure air charger with the perfume generating means also includes air cooling and purifying filter sections 16a, 16b, 16c as means for purifying as well as compressed air.

The air cooling and purifying filter units 16a, 16b and 16c are connected to respective discharge / suction lines 13a and 13b for connecting the respective compression units 10a, 10b and 10c of the multi-stage compression type compressor 12, The negative discharge line 15, and the like.

For example, one air cooling and purifying filter section 16a is provided on the discharge / suction line 13a between the first stage compression section 10a and the second stage compression section 10b, and the second stage compression section 10b And the other air cooling and purifying filter portion 16b is provided in the discharge / suction line 13b between the first-stage compressing portion 13c and the third-stage compressing portion 10c, 15 is provided with another air cooling and purifying filter portion 16c.

Normally, the air introduced from the outside always contains moisture, and in particular, when the air is compressed by a compressor using lubricating oil, the oil component may be mixed into the compressed air.

Therefore, the air cooling and purifying filter units 16a, 16b and 16c are provided with a coalescing filter (not shown) or the like in order to filter the oil components remaining in a large amount of compressed air supplied from each compression unit. And a cooler (not shown) or a dryer (not shown) may be incorporated to remove water and the like.

The oxygen and nitrogen concentration-regulated high-pressure air charger equipped with the perfume generating means is located at the rear end of the air cooling and purifying filter unit side and includes condensed water separators 26a and 26b as means for removing water.

The condensed water separating units 26a and 26b may be installed in the discharge / suction line 13b connecting the compression units 10b and 10c of the multi-stage compression type compressor 12 and the discharge line 15 of the final compression unit do.

For example, on the discharge / suction line 13b between the second stage compressing section 10b and the third stage compressing section 10c, one condensed water separating section 26a is provided on the rear end side of the air cooling and purifying filter section 16b, And another discharge line 15 extending from the discharge side of the third stage compressing section 10c is provided with another condensed water separating section 26b at the rear end side of the air cooling and purifying filter section 16c.

Here, the condensed water separating units 26a and 26b have a structure including an oil water separating function, and the condensed water in the compressed air can be removed using the centrifugal force principle.

Since the moisture remaining in a large amount of compressed air is removed by the condensed water separating sections 26a and 26b, the quality of the compressed air finally supplied can be ensured and the temperature deviation between the components can be minimized in the high- .

The high-pressure air purifier 27 is provided on the discharge line 15 extending from the third-stage compressing section 10c, that is, on the final discharge side of the compressed air at the position of the rear end side of the condensed water separating section 26b, The foreign matter contained in the high-pressure compressed air is finally removed, and it can be supplied to the user with the perfume contained in the high-pressure compressed air.

The high-pressure air purifier 27 includes a dehumidifying agent and a deodorant for removing carbon monoxide or carbon dioxide, which are moisture, odor, and harmful gas in the compressed air, and includes a material generating a perfume. It is possible to effectively remove impurities and the like in the compressed air and to add a perfume that gives a refreshing feeling to the compressed air.

That is, the high-pressure air purifier 27 serves to filter moisture, odor, and noxious gas contained in the compressed air. In particular, the high-pressure air purifier 27 discharges compressed air mixed with a perfume by using a built- .

The high pressure air purifying section 27 includes a cylindrical purifying section main body 27c and a dehumidifying agent layer 27d filled in the purifying section main body 27c and a deodorant layer 27e and a perfume layer 27f do.

The inlet 27a and the outlet 27b of the purifier main body 27c are formed with an inlet 27a for receiving the compressed air and an outlet 27b for discharging the purified compressed air. Side discharge line 15 extending from the discharge side 26b and the discharge-side discharge line 15 extending to the use side.

The dehumidifying agent layer 27d, the deodorant layer 27e and the perfume layer 27f may be sequentially stacked in the purifying section main body 27c.

For example, the dehumidifying agent layer 27d, the deodorant layer 27e, and the perfume layer 27f can be stacked in this order from the inlet 27a of the purifying section main body 27c.

At this time, the order of lamination of the dehumidifying agent layer 27d and the deodorant layer 27e may be changed. In the case of the perfume layer 27f, it is preferable that the deodorant layer 27d is disposed on the uppermost layer in the purifying section main body 27, desirable.

The deodorant layer may be a particle or granular type charcoal, silica gel, activated alumina, opal, activated carbon, etc. The deodorant layer may be a particle or granular photocatalyst, alumina, silica, activated carbon, zeolite, etc. .

Particularly, in the case of the perfume layer, a mint leaf, a petal, a pine needle, etc. may be dried and pulverized into particles.

Therefore, the compressed air supplied to the user or the user in the multi-stage compression type compressor can be supplied by mixing the fragrance with the oxygen adjusted to have a concentration suitable for respiration, so that the air is always fresh and pleasant There is an advantage to breathing.

On the other hand, the compressed air including the fragrance supplied to the user or the place of use as described above may be stored in a container such as a container such as an oxygen cylinder used by a firefighter, an oxygen cylinder used by a skin scuba diver, or the like.

The oxygen and nitrogen concentration control type high pressure air charger includes a solenoid valve and flow meters 20a, 20b, 20c, 19a, an oxygen and nitrogen concentration detection sensor 21 as means for controlling and controlling the oxygen and nitrogen concentration, , And a controller (22).

The solenoid valve and the flow meters 20a, 20b, 20c and 19a are valve devices of a type capable of controlling the amount of opening and closing. The oxygen discharge line 18b and the nitrogen discharge line 18a in the oxygen and nitrogen separator 14, The sub-standby line 17 and the bypass line 19 respectively control the flow rate of air flowing through each line, that is, oxygen, nitrogen, and atmospheric air, and control the flow.

The electromagnetic valve and flow meters 20a, 20b, 20c, and 19a operate under the control of the controller 22, and the flow rate of the air flowing along the line is adjusted .

The oxygen and nitrogen concentration sensor 21 includes a general oxygen sensor (not shown) and a general nitrogen sensor (not shown), and is connected to the two-stage compression unit 10b of the multi- Suction line 13a, and serves to detect the concentration of oxygen and the concentration of nitrogen in the air flowing through the discharge / suction line 13a at this time, respectively.

The oxygen concentration value and the nitrogen concentration value detected by the oxygen and nitrogen concentration detection sensor 21 are provided to the controller 22 so as to be used as basic data for controlling the oxygen and nitrogen concentration.

The controller 22 controls the operation of the solenoid valve and the flow meters 20a, 20b, 20c and 19a and controls the operation of the solenoid valves and the flow meters 20a, 20b, 20c and 19a in various manners .

As an example, the amount of opening and closing of the solenoid valve and the flow meters 20a, 20b, 20c, and 19a can be controlled based on a signal input from the oxygen and nitrogen concentration detecting sensor 21 that detects the concentration of oxygen and nitrogen .

As another example, it is possible to control the amount of opening and closing of the solenoid valve and the flow meters 20a, 20b, 20c, and 19a based on predetermined data (for example, preset opening and closing amounts of the solenoid valve and the flow meter).

An example of a method of controlling the operation of each of the solenoid valves and the flow meters 20a, 20b, 20c, and 19a through the output control of the controller 22 to control the oxygen or nitrogen concentration will be described below.

For example, when the oxygen or nitrogen concentration is 100% by volume, the solenoid valve and flow meter 20c provided in the sub waiting line 17 and the solenoid valve and flow meter 19a of the bypass pipe 19 are completely The solenoid valve and the flow meter 20b provided in the oxygen discharge line 18b of the oxygen and nitrogen separator 14 are fully opened and the solenoid valve and the flowmeter provided in the nitrogen discharge line 18a are opened completely, It is possible to supply the oxygen concentration of 100 vol% while completely closing the solenoid valve and the flow meter 20b provided in the oxygen discharge line 18b of the oxygen and nitrogen separator 14 and In addition, when the solenoid valve and the flow meter 20a provided in the nitrogen discharge line 18a are completely opened, it is possible to supply a nitrogen concentration of 100 vol%.

As another example, when the oxygen or nitrogen concentration is 50% by volume, the solenoid valve and the flowmeter 19a of the bypass pipe 19 are closed 100%, and the solenoid valve and the flow meter The amount of opening and closing of the solenoid valve and the flowmeter 20b provided in the oxygen discharge line 18b of the oxygen and nitrogen separator 14 is opened by 50% and the nitrogen discharge line 20c is opened by 50% When the solenoid valve and the flow meter 20a provided in the valve 18a are completely closed, it is possible to supply the oxygen concentration of 50 vol% (the oxygen concentration relative to 100 vol% of the oxygen concentration supplied in the above example) of 50 vol% On the other hand, the solenoid valve and the flow meter 20b provided in the oxygen discharge line 18b of the oxygen and nitrogen separator 14 are completely closed and the solenoid valve and the flow meter 20a provided in the nitrogen discharge line 18a are closed, Is opened 50%, the nitrogen concentration is 50 parts %, It is possible to supply the (relative nitrogen concentration of 50% by volume to 100% by volume nitrogen concentration to be supplied in an example of the above preparation)
