Description

The present invention relates to an apparatus capable of simultaneously obtaining hot air, cold air, electricity, concentrated oxygen, and concentrated nitrogen.

There is a device called a vortex tube as a device for simultaneously obtaining hot air and cold air. This vortex tube is a T-shaped metal pipe, and you can easily get cold and hot air just by blowing compressed air into it.

However, in order to obtain only hot air, it is possible to freely generate hot air at a desired temperature as long as it has a dryer, not the vortex tube. Therefore, when the vortex tube is used, the actual condition is mainly to cool the heat generated during machining.

In this case, even if compressed air is generated and sent to the vortex tube, it is not necessary in terms of energy to use only cold air and throw it away without using hot air. In order to make the most of the energy of compressed air, how to efficiently generate hot air and cold air, the vortex tube has been improved in the past as described in the patent publication of the prior art document. Has been. As a result, cold air obtained from the vortex tube can be obtained at a lower temperature, and hot air can be obtained at a higher temperature.

However, there has been a demand for a multipurpose device that can further expand the usage of the vortex tube. However, among the conventional devices, as in the present invention, elements other than concentrated oxygen, concentrated nitrogen, electric cold air, and hot air are used. However, there was no vortex tube technology available at the same time.

Here, looking at the composition of air, nitrogen is about 78%, oxygen is about 21%, and argon is about 1%, which is overwhelmingly nitrogen and oxygen. The molecular mass of oxygen and nitrogen is 32 g and 28 g, respectively. Since air has a phenomenon of convection and diffusion, nitrogen and oxygen constituting the air are not normally separated.

However, it was newly found that nitrogen and oxygen in the air were centrifuged due to the mass difference of the gas when compressed air was blown into the pipe from the tangential direction to generate a high-speed rotating vortex.

Therefore, compressed air is supplied to the vortex tube to generate a rotating vortex, so that when the gas outside the rotating vortex is taken out, high-temperature concentrated oxygen is obtained, and conversely, low-temperature concentrated nitrogen is supplied from the center of the rotating vortex. As a result of the experiment, it was found that it can be obtained. In this way, there was no one who had previously studied that air could be separated and concentrated by a rotating vortex, and there was no such technology in the existing technology, and it was discovered for the first time this time. is there.

An embodiment of the present invention will be described with reference to FIGS. 1 to 9, and a conventional vortex tube will be described with reference to FIG.

FIG. 10 is a cross-sectional view of a conventional vortex tube. In FIG. 10, 1 is a vortex tube, 2 is a compressed air supply device, 3 is a compressed air supply port, 4 is a pipe, 5 is a regulating valve, 6 is a cold air discharge port, 7 is a hot air discharge port, 12 is an air compressor, Reference numeral 13 denotes a motor, 22 is cold air, 23 is hot air, 28 is a chamber, 30 is a cold air pipe, 31 is a hot air pipe, and 32 is compressed air. The structure and operation of a conventional vortex tube will be described with reference to FIG. In FIG. 10, the vortex tube 1 is configured such that a joint portion between a short cold air pipe 30 and a long hot air pipe 31 is a chamber 28. A pipe 4 provided with a compressed air supply port 3 is connected in a T-shape so that compressed air 32 is supplied perpendicularly to a straight line formed by the cold air pipe 30, the chamber 28 and the hot air pipe 31 and from the tangential direction of the joint. It is. When compressed air 32 is blown into the compressed air supply port 3, the compressed air 32 rotates at a high speed in the chamber 28, the cold air pipe 30, and the hot air pipe 31. However, the central air is discharged from the cold air discharge port 6 of the short cold air pipe 30 and the air on the inner wall side is discharged from the hot air discharge port 7 of the long hot air pipe 31 as cold air 22 and hot air 23, respectively. . Although this is due to the vortex effect, the hot air 23 discharged from the long hot air pipe 31 is relatively rarely used, but the cold air 22 discharged from the short cold air pipe 30 is mainly used industrially. ing. The gas discharge temperature and the discharge amount can be adjusted by the adjusting valve 5.

FIG. 1 shows an embodiment of the present invention. In FIG. 1, 1 to 7, 12, 13, 22, 23, 28, 30, 31, and 32 are the same as those in FIG. 8 is a nitrogen outlet, 9 is an oxygen outlet, 10 is a thermoelectric element, 11 is a turbine generator, 24 is concentrated nitrogen, 25 is concentrated oxygen, 27 is a radiator, and 33 is a turbine generator cover pipe. The vortex tube 1 according to the present embodiment has a connection portion connecting the cold air pipe 30 and the hot air pipe 31 as a chamber 28 and a compressed air supply port at one end so that the compressed air 32 can be blown from the tangential direction of the inner wall of the chamber 28. 3, the cold air outlet 6 is provided in the axial direction of the cold air pipe 30, and the thermoelectric element 10 and the radiator 27 are provided in the cold air outlet 6. Further, the adjusting valve 5 is provided in the axial direction of the other end of the hot air pipe 31, and the thermoelectric element 10, the radiator 27, the turbine generator 11, and the turbine generator cover pipe 33 covering the thermoelectric element 10 are provided at the hot air outlet 7.

At this time, power is generated by the thermoelectric element 10 using the temperature difference between the cold air 22 and the outside air. At this time, the temperature difference is further increased by the radiator 27 in close contact with the thermoelectric element 10. The compressed air 32 outside the hot air pipe 31 becomes hot air 23 and is discharged from the hot air outlet 7, which is also the concentrated oxygen 25. Also here, power is generated by the thermoelectric element 10 using the temperature difference between the hot air 23 and the outside air. Also at this time, since the heat radiator 27 is provided in close contact with the thermoelectric element 10, a temperature difference is further generated, which is efficient. Furthermore, the turbine generator 11 provided at the hot air outlet 7 can also generate power. And since the composition of the obtained cold air 22 and the hot air 23 is the concentrated nitrogen 24 and the concentrated oxygen 25, respectively, these are taken out from the nitrogen extraction port 8 and the oxygen extraction port 9, respectively. At this time, the cold air outlet 6 also serves as the nitrogen outlet 8, and the hot air outlet 7 also serves as the oxygen outlet 9. In this way, cold air 22, hot air 23, concentrated nitrogen 24, concentrated oxygen 25, and electricity can be obtained from compressed air 32 at a time.

The generation of electric power is expected to be larger than that of the embodiment. However, since the temperature of the hot air 23 obtained after operating the power generation turbine 11 is lowered and the concentration rate of the concentrated oxygen 25 is lowered, when the concentrated oxygen 25 is desired to be obtained, it is provided at the end of the hot air pipe 31. The hot air 23 and the concentrated oxygen 25 obtained from the hot air side surface extraction pipe 35 are used.

A fourth embodiment of the present invention will be described with reference to FIG. In FIG. 5, 1-9, 11-13, 22-26, 28, 30-33 are the same as FIG. Reference numeral 10 denotes a thermoelectric element. In the present embodiment, the cold air side pipe 34 and the hot air side outlet pipe 35 provided on the side surfaces of both ends of the cold air pipe 30 and the hot air pipe 31 provided in FIG. 4 are removed, and the thermoelectric element 10 is provided. It is. In the case of the present embodiment as well, as in the third embodiment, it is possible to take out five elements of cold air 22, hot air 23, concentrated nitrogen 24, concentrated oxygen 25, and electricity. In the case of the present embodiment, the shape of the turbine generator cover pipe 33 covering the turbine generator 11 is a straight pipe without expanding the vortex tube 1 side, and the radiator 27 is removed. This is effective for improving productivity by simplifying. However, the power generation efficiency in this case is slightly lower than in the previous embodiment.

A fifth embodiment of the present invention will be described with reference to FIG. In FIG. 6, reference numerals 1 to 10, 12, 13, 22 to 25, 28, 30, 31, and 32 are the same as those in FIG.

After cooling while rotating the flow path 38, it goes out of the pipe 4, and as a result, the temperature difference between the front and back of the thermoelectric element 10 becomes larger and more current is obtained. Of course, since this is an embodiment, the thermoelectric element 10 may be provided not on the hot air pipe 31 side but on the cold air pipe side as in this embodiment. In this case, on the contrary, the thermoelectric element 10 generates electricity by cooling the inner side and heating the outer side. The thermoelectric element 10 is described as being formed in a ring shape in the figure, but even if it is a commercially available flat type, the flow path of the cold air 22 and the hot air 23 can be secured according to the shape. Since this is the same effect, this method can be used and can be produced at low cost.
