[0019] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, as shown in Figure 1 and Figure 2As shown in the figure, an adsorption type air oxygen-nitrogen separation device includes a separation cylinder 1. A filtering mechanism 5 is fixedly connected to the lower part of the inner surface of the separation cylinder 1. A condensation mechanism 6 is fixedly connected to the middle and lower part of the inner surface of the separation cylinder 1. A collection mechanism 2 is arranged on one side of the condensation mechanism 6. A compression mechanism 7 is fixedly connected to the middle part of the inner surface of the separation cylinder 1. A separation mechanism 8 is fixedly connected to the upper part of the inner surface of the separation cylinder 1. A conveying mechanism 3 is fixedly connected to the middle and upper part of one side of the outer surface of the separation cylinder 1. A spraying mechanism 4 is fixedly connected to the side of the outer surface of the separation cylinder 1 away from the conveying mechanism 3.

[0021] When it is necessary to separate nitrogen and oxygen in the air, the air to be separated is introduced into the interior of the separation cylinder 1 from the lower part of the inner surface of the separation cylinder 1. Subsequently, through the cooperation of the filtering mechanism 5 for filtering, solid particles in the air, impurity liquids such as oil stains in the air, etc. are filtered. After the preliminary filtration, the air slowly passes through the condensation mechanism 6. Through the cooperation of the condensation mechanism 6, the water vapor in the air is condensed and collected in cooperation with the collection mechanism 2. While removing the water vapor in the air, the air is synchronously cooled. The air after removing the water vapor flows to the separation mechanism 8 after being compressed by the compression mechanism 7. Through the cooperation of the separation mechanism 8, the nitrogen in the air is adsorbed, and the oxygen will overflow above the separation mechanism 8 and the upper part of the inner surface of the separation cylinder 1. Subsequently, the separated oxygen is collected by a collection device in the prior art.

[0022] While compressing the cooled air by the compression mechanism 7, the condensed water collected is conveyed to the periphery of the compression mechanism 7 in cooperation with the collection mechanism 2 to cool the compression mechanism 7 and avoid local overheating caused by long-term operation.

[0023] After the condensed water cools the compression mechanism 7, the water temperature rises, and the heated water will be collected and reheated in cooperation with the conveying mechanism 3. After the oxygen collection is completed, through the cooperation of the separation mechanism 8 and the conveying mechanism 3, heating and pressure reduction desorption are carried out to release the adsorbed nitrogen in the separation mechanism 8. The hot water of the conveying mechanism 3 is used to further improve the desorption efficiency of the separation mechanism 8. At the same time, after the nitrogen in the separation mechanism 8 is desorbed and collected, the water in the conveying mechanism 3 is sprayed above the filtering mechanism 5 by the spraying mechanism 4 to wash the filtering mechanism 5 from top to bottom, avoiding the influence of solid particles and impurities such as oil stains adsorbed by the filtering mechanism 5 on the subsequent use of the filtering mechanism 5.

[0024] During the operation of this embodiment, the condensation mechanism 6 cooperates with the compression mechanism 7 to cool the air while removing water vapor from the air, reducing the energy consumption of the compression mechanism 7 for compressing air. At the same time, the collection mechanism 2 cooperates with the conveying mechanism 3 to cool the compression mechanism 7 using the collected condensed water. Subsequently, reheating with the heated water can also assist the separation mechanism 8 in the operation of desorbing nitrogen. After the water that has dissipated heat from the separation mechanism 8, the waste heat is used to wash the filtration mechanism 5 through the spraying mechanism 4, reducing the replacement frequency of the filtration mechanism 5 and facilitating the adsorption of impurities by the filtration mechanism 5 during subsequent air filtration.

[0025] Embodiment 2. On the basis of Embodiment 1, this embodiment aims to achieve the effect of multi-stage collaborative nitrogen-oxygen separation in filtration, condensation, compression, and separation.

[0026] Refer to Figure 2 , a water outlet 12 is provided in the middle of the bottom wall of the inner surface of the separation cylinder 1, an air outlet 11 is provided in the middle of the top wall of the inner surface of the separation cylinder 1, and a plurality of first inlet pipes 13 are annularly arranged in the lower part of the inner surface of the separation cylinder 1.

[0027] Through the cooperation of a plurality of first inlet pipes 13, the air to be separated is introduced into the lower part of the inner surface of the separation cylinder 1. At the same time, the inner surface of the air outlet 11 is connected to a commonly used oxygen collection device in the prior art. During nitrogen-oxygen separation, through the cooperation of the air outlet 11, the separated oxygen is continuously collected. Similarly, when the spraying mechanism 4 cooperates to spray and wash the upper part of the filtration mechanism 5, the washed water flows out through the water outlet 12. During the process of oxygen-nitrogen separation, the water outlet 12 is in a sealed state.

[0028] Refer to Figure 3 , the filtration mechanism 5 includes a first filter plate 51 fixedly connected to the inner surface of the separation cylinder 1, and a second filter plate 52 is fixedly connected to the lower side of the inner surface of the separation cylinder 1. The lower end of the second filter plate 52 is higher than the upper ends of the plurality of first inlet pipes 13.

[0029] Both the above-mentioned second filter plate 52 and the first filter plate 51 are common technical means in the prior art, mainly used to adsorb solid particles and impurities such as oil stains in the air to avoid the influence of oil stains on subsequent operations.

[0030] Furthermore, the air that enters the lower part of the inner surface of the separation cylinder 1 through the cooperation of a plurality of first inlet pipes 13, after passing through the second filter plate 52 and the first filter plate 51 respectively, the solid particles and oil stains in the air are jointly filtered by the first filter plate 51 and the second filter plate 52, and then the filtered air continues to move upward.

[0031] Refer to Figure 4, the condensation mechanism 6 includes a first filter ring 61 fixedly connected to the inner surface of the separation cylinder 1. The inner surface of the first filter ring 61 is fixedly connected with a first conical guide plate 62. Above the first filter ring 61, a plurality of arc-shaped condensation plates 63 are annularly arranged on the inner surface of the separation cylinder 1. Above the plurality of arc-shaped condensation plates 63, a second filter ring 64 is fixedly connected to the inner surface of the separation cylinder 1. The inner surface of the second filter ring 64 is fixedly connected with a conical condensation plate 65. Above the second filter ring 64, a conical condensation plate 65 is fixedly connected to the inner surface of the separation cylinder 1. A through hole 622 is formed in the bottom wall of the inner arc surface of the first conical guide plate 62, and a second hose 621 is fixedly connected to the inner surface of the through hole 622. Above the second filter ring 64, an adsorption block 66 is fixedly connected to the inner surface of the separation cylinder 1.

[0032] The above-mentioned conical condensation plate 65 and a plurality of arc-shaped condensation plates 63 are both commonly used settings in the prior art. During the operation of the conical condensation plate 65 and a plurality of arc-shaped condensation plates 63, the surface temperature of the conical condensation plate 65 and a plurality of arc-shaped condensation plates 63 continuously decreases. When air passes through, the water vapor in the air is condensed into small water droplets through the combined action of the conical condensation plate 65 and a plurality of arc-shaped condensation plates 63, and the water droplets fall through the inclined settings of the outer arc surface of the conical condensation plate 65 and a plurality of arc-shaped condensation plates 63.

[0033] The above-mentioned adsorption block 66 is an adsorption layer commonly used in the prior art to adsorb water vapor in the air.

[0034] Furthermore, the air filtered by the cooperation of the first filter plate 51 and the second filter plate 52 slowly rises through the first filter ring 61 and enters the upper part of the first conical guide plate 62. At this time, the plurality of arc-shaped condensation plates 63 and the conical condensation plate 65 have been operating for a period of time. When the air rising through the first filter ring 61 encounters the surfaces of the plurality of arc-shaped condensation plates 63 with low temperature and the outer arc surface of the conical condensation plate 65, the water vapor in the air will condense into small water droplets and fall on the inner arc surface of the first conical guide plate 62. At the same time, through the cooperation of the through hole 622 and the second hose 621, the condensed water is timely discharged. Further, while removing the water vapor in the air through the cooperation of the conical condensation plate 65 and a plurality of arc-shaped condensation plates 63, the conical condensation plate 65 and a plurality of arc-shaped condensation plates 63 jointly cooperate to cool the air. Subsequently, the cooled air continues to rise slowly through the second filter ring 64 and passes through the adsorption block 66. Through the cooperation of the adsorption block 66, the water vapor in the air is completely removed to avoid the influence of water vapor on the subsequent adsorption and separation.

[0035] Refer to Figure 7 , the compression mechanism 7 includes an air compressor 73 fixedly connected to the inner surface of the separation cylinder 1. A second intake pipe 74 is fixedly connected to the lower part of the outer surface of the air compressor 73. The lower end of the second intake pipe 74 is fixedly connected with a guide cover 71. An outlet pipe 75 is fixedly connected to the upper part of the outer surface of the air compressor 73. The upper end of the outlet pipe 75 is fixedly connected with a sealing plate 72.

[0036] The air compressor 73 mentioned above is a device commonly used in the prior art for compressing gas. When gas enters the air compressor 73, it will be compressed and then released. At the same time, during the operation of the air compressor 73, a large amount of heat will be generated, and the temperature around the air compressor 73 is relatively high. After the air compressor 73 operates for a period of time, it is necessary to perform heat dissipation and cooling treatment on the air compressor 73. The specific internal structure and operating principle of the air compressor 73 will not be elaborated in detail in this solution.

[0037] The air that has been cooled and had water vapor removed enters the interior of the second intake pipe 74 through the guidance of the guide cover 71 and then passes through the air compressor 73. After being compressed by the air compressor 73, it continues to rise through the outlet pipe 75. At the same time, through the sealing fit between the sealing plate 72 and the inner surface of the separation cylinder 1, the high-pressure air rising through the outlet pipe 75 will not affect the uncompressed air.

[0038] Refer to Figure 9 , the separation mechanism 8 includes a honeycomb guide plate 82 fixedly connected to the inner surface of the separation cylinder 1. An adsorption plate 81 is fixedly connected to the inner surface of the separation cylinder 1 above the honeycomb guide plate 82. The metal pipe 33 is located below the adsorption plate 81.

[0039] The interior of the adsorption plate 81 mentioned above is filled with zeolite molecular sieve, which is commonly used in the prior art, for adsorbing nitrogen and allowing oxygen to pass through, so as to achieve the purpose of oxygen-nitrogen separation.

[0040] Furthermore, the air compressed by the air compressor 73 enters the upper end of the sealing plate 72 through the outlet pipe 75. Through the setting of the honeycomb guide plate 82, the pressurized air rises evenly after passing through the honeycomb guide plate 82. Through the adsorption plate 81, at this time, the nitrogen in the air is adsorbed by the adsorption plate 81, while the oxygen enters the space between the upper end of the adsorption plate 81 and the inner surface of the separation cylinder 1 and enters the collection device fixedly connected to the outside through the air outlet 11, realizing the separation of nitrogen and oxygen.

[0041] After the oxygen collection is completed, the nitrogen adsorbed inside the adsorption plate 81 is released by decompression and then collected by the collection device in the prior art, realizing the separation of nitrogen and oxygen in the air.

[0042] Therefore, in this solution, through the cooperation of the first filter plate 51 and the second filter plate 52 for hierarchical filtration to protect the subsequent modules. At the same time, by using the conical condensation plate 65 in cooperation with the adsorption block 66 and several arc-shaped condensation plates 63 to remove the water vapor in the air, avoiding its impact on the performance of the adsorption plate 81. At the same time, through the cooperation of the air compressor 73 with the adsorption plate 81 and the honeycomb guide plate 82, while increasing the air pressure, the efficiency of the adsorption plate 81 for oxygen-nitrogen separation is enhanced.

[0043] Embodiment 3. On the basis of Embodiments 1 and 2, in order to achieve the effect of using condensed water to absorb the waste heat of the air compressor 73, it is also possible to achieve the effect of heating the adsorption plate 81.

[0044] Refer to Figure 5 and Figure 6 , the collection mechanism 2 includes a water collection box 21 fixedly connected to the outer surface of the separation cylinder 1. A water pump 22 is fixedly connected to the outer surface of the separation cylinder 1. One end of the hose 621 away from the conical guide plate 62 is fixedly connected to one side of the inner surface of the water collection box 21. One end of the water pump 22 is fixedly connected to a water inlet pipe 221, and the water inlet pipe 221 is fixedly connected to the lower side of one side of the water collection box 21. One end of the water pump 22 is fixedly connected to a water outlet pipe 222. The end of the water outlet pipe 222 away from the water pump 22 is fixedly connected to a spiral pipe 23. The end of the L-shaped pipe 27 away from the water outlet pipe 222 is fixedly connected to the spiral pipe 23. Symmetric sliding grooves 211 are formed in the side wall of the inner surface of the water collection box 21. A sliding plate 26 is slidably connected to the two sliding grooves 211. The middle part of the lower end of the sliding plate 26 is fixedly connected to a floating ball 25. The middle part of the top wall of the inner surface of the water collection box 21 is fixedly connected to a button 24, and the button 24 is electrically connected to the water pump 22.

[0045] The water pump 22 above is a conventional design in the prior art. Through the electrical connection with the button 24, when the button 24 is pressed, the water pump 22 can be triggered to operate, and the condensed water inside the water collection box 21 is conveyed upward. The specific internal structure and operating principle of the water pump 22 will not be elaborated in detail in this solution.

[0046] The water condensed by the cooperation of the conical condensation plate 65 and several arc condensation plates 63 is guided by the conical guide plate 62 and cooperated with the hose 621, and the condensed water is timely converged to the inner surface of the water collection box 21. As the condensed water continuously increases, the water level rises. When the condensed water level inside the water collection box 21 rises to start contacting the lower part of the outer surface of the floating ball 25, at this time, the floating ball 25 is subjected to buoyancy. As the water level inside the water collection box 21 rises, the buoyancy received by the floating ball 25 gradually increases. When the buoyancy received by the floating ball 25 is greater than the sum of the gravity of the floating ball 25 and the sliding plate 26, at this time, the water level inside the water collection box 21 continues to rise, and the buoyancy received by the floating ball 25 will continue to increase, thereby pushing the floating ball 25 and the sliding plate 26 upward along the inner surface of the two sliding grooves 211.

[0047] When the floating ball 25 and the sliding plate 26 slide upward until the upper end of the sliding plate 26 starts to contact the lower part of the outer surface of the button 24, at this time, the floating ball 25 and the sliding plate 26 continue to rise and press the button 24. Through the mutual cooperation of the electrical connection between the button 24 and the water pump 22, the water pump 22 is activated to start operating at this time. Immediately, the water pump 22 sucks the condensed water from the inside of the water collection box 21 through the water inlet pipe 221 and discharges it upward through the water outlet pipe 222.

[0048] Furthermore, the condensed water entering the inside of the water collection box 21 through the second hose 621 reaches equilibrium with the condensed water flowing out through the first water inlet pipe 221, keeping the water level in a state where the float ball 25 and the sliding plate 26 press upward on the button 24, that is, the first water pump 22 operates continuously.

[0049] Further, the water discharged through the first water outlet pipe 222 enters the inside of the spiral pipe 23 through the inside of the L-shaped pipe 27. The air compressor 73 is located in the middle of the spiral of the spiral pipe 23. When the condensed water enters from below the spiral pipe 23 and exits from above, the cooling time of the condensed water for the air compressor 73 can be extended, and at the same time, the condensed water can be heated for a longer time.

[0050] Through the heat exchange treatment of the outer surface of the air compressor 73 by the condensed water, after the condensed water is discharged above the spiral pipe 23, the water temperature can reach between 50 - 60 °C, and then the heated water is collected again.

[0051] Refer to Figure 8 , the conveying mechanism 3 includes a thermostat box 31 fixedly connected to one side of the outer surface of the separation cylinder 1. One side of the inner surface of the thermostat box 31 is fixedly connected to one end of the spiral pipe 23. A second water pump 32 is fixedly connected to one side of the outer surface of the separation cylinder 1 near the thermostat box 31. One end of the second water pump 32 is fixedly connected to a second water inlet pipe 321, and the second water inlet pipe 321 is fixedly connected to one side of the inner surface of the thermostat box 31. The upper end of the second water pump 32 is fixedly connected to a second water outlet pipe 322. The end of the second water outlet pipe 322 away from the second water pump 32 is fixedly connected to a metal pipe 33, and the end of the metal pipe 33 away from the second water outlet pipe 322 is fixedly connected to a first hose 34. The lower end of the first hose 34 is fixedly connected to a water tank 35.

[0052] The above-mentioned thermostat box 31 is a conventional design in the prior art, that is, the thermostat box 31 can not only achieve the function of maintaining a constant temperature, but also increase the temperature of water that has not reached the set temperature, and can also cool the water with a temperature higher than the set temperature and then keep it warm.

[0053] After the condensed water realizes heat exchange with the air compressor 73 through the cooperation of the spiral pipe 23, while the condensed water cools the air compressor 73, the temperature of the condensed water itself rises to 50 - 60 °C. Subsequently, the hot water discharged above the spiral pipe 23 enters the inside of the thermostat box 31, and then through the cooperation of the thermostat box 31, the water temperature inside the thermostat box 31 is kept constant at 90 °C.

[0054] Further, when the collection of oxygen is completed and it is ready to perform vacuum desorption of nitrogen on the adsorption plate 81, the water pump two 32 is activated at this time. Meanwhile, the water pump two 32 transfers the 90°C hot water inside the thermostatic chamber 31 to the inside of the outlet pipe two 322 through the inlet pipe two 321, and through the cooperation of the metal pipe 33, continuously heats the lower part of the adsorption plate 81, providing heat for the desorption inside the adsorption plate 81, so that the nitrogen adsorbed inside the adsorption plate 81 is more likely to break away after absorbing heat, further improving the efficiency of vacuum desorption of the adsorption plate 81. The nitrogen that breaks away is collected by the collection device in the prior art.

[0055] The hot water that has dissipated heat through the cooperation of the metal pipe 33 enters the inside of the water tank 35 through the hose one 34.

[0056] Refer to Figure 10 , the spraying mechanism 4 includes a water pump three 41 fixedly connected to the outer surface of the separation cylinder 1. One end of the water pump three 41 is fixedly connected with an inlet pipe three 411. The end of the inlet pipe three 411 away from the water pump three 41 is fixedly connected to one side of the inner surface of the water tank 35. One end of the water pump three 41 is fixedly connected with an outlet pipe three 42. The lower end of the outlet pipe three 42 is fixedly connected with an arc-shaped pipe two 44. The lower part of the outer surface of the outlet pipe three 42 is fixedly connected with an arc-shaped pipe one 43.

[0057] A plurality of spray heads are fixedly connected to the outer surfaces of the above-mentioned arc-shaped pipe one 43 and arc-shaped pipe two 44.

[0058] After the nitrogen inside the adsorption plate 81 is desorbed, by activating the water pump three 41, the water pump three 41 is operated, and then the hot water inside the water tank 35 is discharged from the outlet pipe three 42 through the cooperation of the water pump three 41 through the inlet pipe three 411. Subsequently, the hot water discharged through the outlet pipe three 42 is sprayed out through the arc-shaped pipe one 43, the arc-shaped pipe two 44 and a plurality of spray heads respectively.

[0059] The sprayed hot water respectively falls above the filter plate one 51 and the filter plate two 52, falls by the gravity of the hot water itself, and cleans the solid particles, oil stains and other impurities adsorbed and filtered by the filter plate one 51 and the filter plate two 52. The falling water finally converges at the bottom wall of the inner surface of the separation cylinder 1 and flows out through the water outlet 12, realizing the self-cleaning effect of the filter plate one 51 and the filter plate two 52 after the oxygen-nitrogen separation is completed, improving the utilization rate of the filter plate one 51 and the filter plate two 52 and the next filtering effect.

[0060] Therefore, this solution utilizes the small water droplets formed during the process of removing water vapor from the air. At the same time, through the cooperation of the floating ball 25, the sliding plate 26 and the button 24, the operation of the first water pump 22 is triggered, achieving the effect that the condensed water and the air compressor 73 can conduct heat exchange. While the condensed water cools down the air compressor 73, the condensed water heats up. Subsequently, through the cooperation of the thermostat 31, the warm water is heated and then through the cooperation of the metal pipe 33, the area below the adsorption plate 81 is continuously heated, providing heat for the desorption of nitrogen in the adsorption plate 81, accelerating the separation of nitrogen, further improving the efficiency of nitrogen-oxygen separation. At the same time, the heated water can also spray and wash the upper ends of the first filter plate 51 and the second filter plate 52, realizing the self-cleaning function, avoiding the frequent replacement of the first filter plate 51 and the second filter plate 52, and also avoiding the situation that the first filter plate 51 and the second filter plate 52 are blocked due to lack of cleaning and resulting in poor filtering effect in the follow-up. Overall, through the cooperation between various structures, utilizing the water temperature of the condensed water and the waste heat of the air compressor 73, the energy consumption of the device operation is further reduced.

[0061] It should be specifically noted that the specific installation methods, circuit connection methods and control methods of the second water pump 32 and the third water pump 41 adopted in the present invention are all conventional designs, and the present invention will not elaborate in detail.
