Description

Moisture eliminator in oxygen producing device

The present invention relates to a water remover of the oxygen generator for removing water contained in the oxygen in the process of transporting the oxygen generated from the oxygen generator to the demand.

An oxygen generator is a mechanical device that separates air sucked from the outside into oxygen and a gas other than oxygen, and supplies the separated oxygen to a demand destination that requires it. There are many kinds of such oxygen generators, for example, oxygen generators employing PSA (Pressure Swing Adsorption), or oxygen generators employing membrane separation using flat or hollow fiber membranes.

On the other hand, an oxygen transport line is installed to supply oxygen generated from the oxygen generator to the demand destination. The oxygen transport line is connected to the oxygen outlet of the oxygen generating device is configured with a pipe or hose (hose) for moving the oxygen generated in the oxygen generating device to the demand. Since the oxygen transport line may have a flow resistance when the length thereof is long, a booster such as a booster pump may be separately installed to allow oxygen to be sent farther.

Oxygen that flows internally along the oxygen transport line contains water, which often generates water droplets, that is, condensed water, due to temperature and pressure differences between the outside and the inside of the oxygen transport line. However, the above-mentioned water droplets generated in the oxygen transport line may corrode the inside of the oxygen transport line or the boost pump. In addition, there is a problem that the water droplets may be discharged directly into the room or the interior of the vehicle that is the demand for oxygen may cause discomfort to the user of the oxygen generating device.

The present invention has been made to solve the above problems, the object of the present invention is to provide a moisture remover of the oxygen generating device that can provide a refreshing feeling to the consumer of oxygen by removing the water contained in the oxygen generated in the oxygen generating device. It is done.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention. Basically, the water remover of the oxygen generating device according to the present invention is applicable to the oxygen generating device of the indoor as well as the vehicle, the following detailed description will be described with reference to the example of applying the oxygen generating device to the vehicle.

1 is a schematic view showing an oxygen supply system to which a water remover of an oxygen generator according to an embodiment of the present invention is applied, and FIG. 2 schematically shows an embodiment of a water remover of the oxygen generator according to the present invention. It is sectional drawing.

As shown in FIG. 1, the oxygen generator 2 is installed in the trunk of the vehicle 1. Oxygen generated from the oxygen generator 2 passes through the water remover 10 to remove moisture, and is discharged through the front grill G inside the vehicle 1. Meanwhile, as illustrated in FIG. 2, the water remover 10 of the oxygen generator according to the preferred embodiment includes a first housing 20 including a first water filter 25 and a second water filter 45. And a second housing 40 including a moisture absorbent 50. In addition, an oxygen transport line for transporting oxygen from the oxygen generator (2) to the interior of the vehicle (1), the first oxygen line 12 extending from the oxygen generator (2) to the first housing (20) and And a second oxygen line 14 extending from the first housing 20 to the second housing 40, and extending from the second housing 40 to the front grill G inside the vehicle 1. A third oxygen line 16 is provided.

The first housing 20 includes a first inlet 21, the first outlet 22, and a drain 23, and an inner space is provided. The first inlet 21 is provided at one side of the first housing 20 and is connected to the first oxygen line 12 so that oxygen generated in the oxygen generator 2 is introduced therethrough. . A predetermined oxygen inflow passage 27 extending from the first inlet 21 is provided inside the first housing 20, so that oxygen introduced through the first inlet 21 is transferred to the first housing 20. To the inner space of the The first outlet 22 is provided at the other side of the first housing 20, and through the first inlet 21 and the oxygen inlet passage 27, the first outlet 22 is provided in the inner space of the first housing 20. Inflow of oxygen flows out. A predetermined oxygen outlet passage 28 extending from the first outlet 22 is provided inside the first housing 20, so that oxygen in the inner space of the first housing 20 may be transferred to the first outlet 22. Guide). The drain port 23 is provided at the lower side of the first housing 20, through which the water droplets 7 formed by condensing moisture contained in oxygen introduced into the inner space of the first housing 20 are formed. 1 Discharge to the outside of the housing 20. A drain pipe 18 is connected to the drain port 23, and a solenoid valve 35 provided to open and close the drain port 23 is connected to the drain pipe 18 according to an electrical signal from the vehicle 1.

The first water filter 25 is installed in the inner space of the first housing 20. The first water filter 25 has a cylindrical shape having openings at upper and lower ends thereof, and the opening at the upper end of the first water filter 25 is formed at an end of the inner space side of the first housing 20 of the oxygen inflow passage 27. The opening at its lower end is closed by the first water filter cap 26. In the illustrated exemplary embodiment, the first water filter 25 may be made by sintering polyethylene (PE) powder. The polyethylene (PE) powder sintering means that the polyethylene (PE) powder is press-molded in a cylinder form and then heated to a temperature close to the melting point so that the powders are bonded to each other or connected to each other by vapor deposition to maintain the cylinder form. I say that. The first water filter 25 made by the polyethylene (PE) powder sintering method has numerous micropores which are sintered and formed between adjacent powder particles. Therefore, when oxygen containing water passes through the sidewall of the first water filter 25, the oxygen containing water continuously strikes the polyethylene (PE) powder and the pressure increases. Such a rise in pressure causes some of the moisture contained in the oxygen to condense so that the moisture becomes water. However, oxygen does not liquefy because it does not reach condensation conditions despite the rise in pressure. The first water filter 25 is not limited to polyethylene (PE) sintering as long as it has a structure having a large number of micropores, such as a nonwoven fabric or a copper sintered product. However, the water filter by polyethylene (PE) sintering is preferable to those mentioned above in terms of ease of molding and strength or cost.

The first oxygen line 12 is made of a pipe or hose, one end of which is connected to the oxygen generator 2 and the other end of which is connected to the first inlet 21 of the first housing 20. . In the illustrated preferred embodiment, the length is 1 m or more, and the reason thereof is as follows. A temperature difference between the first oxygen line 12 and the inside and outside of the vehicle 1 during operation of the vehicle 1 is generally generated. In particular, in winter, the temperature outside the first oxygen line 12 is minus 10 degrees Celsius. While falling below, the temperature inside the first oxygen line 12 may be at least 30 degrees Celsius, resulting in a temperature difference of at least 40 degrees Celsius. As a result of condensation due to the temperature difference between the inside and the outside, water droplets 7 may be formed by partially condensing moisture contained in oxygen on the inner wall of the first oxygen line 12. According to the illustrated embodiment, the length of the first oxygen line 12 is set to 1 m or more, so that the water droplets 7 move in the same direction as the flow direction of oxygen and attract the surrounding moisture and become larger and larger. After being introduced into the first housing 20 together with the oxygen in a larger state, it may be discharged through the drain port 23.

The second housing 40 has a cylindrical shape having an internal space, and includes a second inlet 41 through which the oxygen flowing out through the first outlet 22 of the first housing 20 flows into the lower end thereof. A second outlet 42 through which the oxygen introduced through the second inlet 41 flows is provided at the upper end. The second housing 40 is provided with a moisture adsorbent 50 for adsorbing some moisture contained in oxygen introduced into the second housing 40. In the preferred embodiment shown, the moisture adsorbent 50 is comprised of a large number of alumina particles having a number of diameters of several millimeters in diameter. Since the alumina particles are occupied by upper and lower wire meshes 53 and 54 having a mesh of a diameter smaller than the diameter of the alumina particles, the second inlet 41 or second of the second housing 40 is limited. 2 outlet 42 is prevented from being blocked by the alumina particles. Instead of the alumina particles, for example, silica gel may be used as the moisture adsorbent 50 if the water adsorbent has a property of adsorbing water, but the silica gel has a poor water adsorption performance compared to the alumina particles, and also absorbs moisture. It is liable to be brittle in a state, which may block the wire meshes 53 and 54, which is not preferable compared to alumina particles.

In the preferred embodiment shown, a second moisture filter 45 is provided inside the second housing 40 to condense some of the moisture contained in the oxygen. The second water filter 45 may be formed in the second housing 40 to allow oxygen introduced into the inner space of the second housing 40 to pass therethrough prior to reaching the water absorbent 50. It is installed below the moisture absorbent (50). Similarly to the first water filter 25, the second water filter 45 has a cylindrical shape having openings at upper and lower ends thereof, and the opening at the lower end thereof is connected to the second inlet 41. The opening at the upper end thereof is blocked by the second water filter cap 46. The second water filter 45 may also be made by sintering polyethylene (PE) powder like the first water filter 25. However, in the preferred embodiment shown, the second water filter 45 is made by sintering a so-called fine powder having finer particles than the polyethylene (PE) powder used in the manufacture of the first water filter 25. The second water filter 45 made as described above is provided with numerous micropores having a smaller inner diameter than the first water filter 25. Therefore, when oxygen containing water passes through the side wall of the second water filter 45, water droplets are generated by the same mechanism as the water generation mechanism by the first water filter 25. However, due to the difference in the micropores of the first water filter 25 and the second water filter 45, most of the water droplets 7 may pass through the micro holes of the first water filter 25. In addition, most of the droplets 7 may not pass through the micro-pores of the second moisture filter 45. Similarly to the first water filter 25, the second water filter 45 is not limited to polyethylene (PE) sintering. For example, a nonwoven fabric, a copper sintered product, or the like can also be used.

The second oxygen line 14 is formed of a pipe or hose, one end of which is connected to the first outlet 22 of the first housing 20 and the other end of the second housing 40. 2 is connected to the inlet (41). The second oxygen line 14 extends upwardly from the first outlet 22 of the first housing 20 to the second inlet 41 of the second housing 40, but is illustrated in FIG. 2. It is shown cut for. Accordingly, the second inlet 41 is actually positioned higher than the first outlet 22, but in FIG. 2, the second inlet 41 is shown as being lower than the first outlet 22. . In the preferred embodiment shown by the above configuration, the water droplet 7 generated during the passage of oxygen through the second water filter 45 and not passing through the second water filter 45 is Along the second oxygen line 14 flows in the direction opposite to the flow direction of oxygen from the second inlet 41 toward the first outlet 22 and flows back into the inner space of the first housing 20. Can be.

The third oxygen line 16 is made of a pipe or hose, one end of which is connected to the second outlet 42 of the second housing 40 and the other end of the grille G of the vehicle interior (FIG. 1). Reference). However, the other end of the third oxygen line 16 may be connected to a sun visor so as to discharge oxygen closer to the driver's head, as shown in FIG.

Hereinafter, the operation of the water remover 10 of the oxygen generating device according to a preferred embodiment of the present invention having the above structure.

When the driver of the vehicle 1 operates the oxygen generator 2, the oxygen generator 2 generates oxygen, and the oxygen is generated in the first housing 20 through the first oxygen line 12. 1 to the inlet (21). As described above, the first oxygen line 12 condenses some of the moisture contained in the oxygen due to condensation, thereby generating water droplets 7, and the water droplets 7 together with oxygen form the first water droplets. It is introduced into the first housing 20 through the inlet 21. The oxygen and the water droplets 7 are introduced into the first water filter 25 in the form of a cylinder along the oxygen inflow passage 27 in the first housing 20, by the first water filter cap 26. The flow is redirected to pass through the first water filter 25. As described above, some of the moisture contained in the oxygen is condensed by the micro-pores of the first moisture filter 25 to form the water droplets 7. At this time, the micro-pores of the first water filter 25 is large enough to allow the water droplets 7 to pass through the water droplets 7, as described above, and the water droplets generated and flowed from the first oxygen line 12 (7). ) And most of the water droplets 7 generated while passing through the first water filter 25 pass through the first water filter 25. The water drop 7, which has passed through the first water filter 25, is accumulated under the inner space of the first housing 20 by gravity.

The oxygen passing through the first water filter 25 is introduced into the second inlet 41 of the second housing 40 through the oxygen outlet passage 28 and the second oxygen line 14 in order. The oxygen is introduced into the second water filter 45 in the form of a cylinder, and the flow is redirected by the second water filter cap 46 to pass through the second water filter 45. Some of the water contained in the oxygen passing through the second water filter 45 is condensed by the micro-pores of the second water filter 45 to form a water drop 7. However, since the micropores of the second water filter 45 are not large enough to pass the water droplets 7, unlike the micropores of the first water filter 25, the generated water droplets ( 7) does not pass through the second water filter 45 in most cases. As described above, the water droplets 7, which do not pass through the second water filter 45, are reversed by the gravity as opposed to the flow of oxygen, and flow into the internal space of the first housing 20 through the second oxygen line 14. Then, the first housing 20 is accumulated in the lower side of the inner space.

The oxygen passing through the second water filter 45 passes through the water absorbent 50 and is discharged to the interior of the vehicle 1 via the third oxygen line 16. Some of the water contained in the oxygen is adsorbed to the moisture absorbent 50 while passing through the moisture absorbent 50.

On the other hand, when the solenoid valve 35 is opened, the droplet 7 accumulated in the lower side of the inner space of the first housing 20 passes through the drain port 23 and is discharged to the outside through the drain pipe 18. The solenoid valve 35 is converted into a position to open the drain opening 23 by a predetermined electric signal, for example, about 20 seconds per hour, for example, by a battery of a vehicle, and then again after a predetermined time. It may be converted to a position to close the drain 23.

As described above, the water remover 10 of the oxygen generator according to the preferred embodiment, the oxygen in the first oxygen line 12, the first water filter 25, and the second water filter 45. The water contained in the oxygen is condensed in water and separated and discharged, and by adsorbing and separating the water contained in the oxygen by the water absorbent 50, the water contained in the oxygen can be removed in multiple stages.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. For example, the water remover 10 of the oxygen generator according to the present invention, the oxygen generated in the oxygen generator 2 is pressurized to open the first, second, and third oxygen line (12. 14. 16) It may be provided with pressurizing means such as a blower so as to flow along. As another example, the first housing 20 or the second housing 40 may be divided into two or more parts so as to easily clean the interior of the first housing 20 or the second housing 40 or replace internal components. It can also be configured to be separated and combined. Meanwhile, the moisture absorbent 50 and the wire meshes 53 and 54 may be configured as a module so that the moisture absorbent 50 whose moisture adsorption performance is lost due to use can be easily replaced. Therefore, the true scope of protection of the present invention should be defined only by the attached utility model registration claims.

The water remover of the oxygen generator described above may reduce the absolute humidity by removing the water contained in the oxygen generated by the oxygen generator, thereby providing a refreshing feeling to the user of the oxygen.

In addition, by providing a first oxygen line having a length of 1m or more, and further comprising a second moisture filter and a moisture adsorbent, or by optionally providing the above-mentioned can further improve the performance of water removal.
