Description

Technical Field

[0001] This utility model relates to the technical field of oxygen supply equipment, specifically to a space-diffuse oxygen supply equipment applied in plateau areas. Background Technology

[0002] In the 1970s, Union Carbide Corporation in the United States first industrialized pressure swing adsorption (PSA) oxygen production, subsequently developing vacuum desorption (VPSA) technology, which significantly reduced energy consumption by regenerating molecular sieves under negative pressure. In recent years, with the upgrading of domestic lithium-based molecular sieve products, adsorption capacity has increased by 8%, and service life has reached over 10 years. VPSA oxygen production technology, with its advantages of low pressure adaptability, low energy consumption, and intelligent operation, has become a disruptive solution for high-altitude oxygen supply. However, adsorption oxygen production requires a cyclical adsorption-desorption process; oxygen cannot be produced during desorption, thus preventing continuous oxygen production.

[0018] Example 1 A space-diffusion oxygen supply device for use in high-altitude areas includes an air supply component 1, a desorption component 2, a first adsorber 3, a second adsorber 3', and an air storage component 4.

[0019] The first adsorber 3 and the second adsorber 3' both include a tower body 31, within which an air chamber 3a, an adsorption chamber 3b, and an oxygen chamber 3c are provided. The air chamber 3a and the adsorption chamber 3b are separated by a first grid 33, and the adsorption chamber 3b and the oxygen chamber 3c are separated by a second grid 34. The adsorption chamber 3b is filled with a molecular sieve 35. The air chamber 3a, the adsorption chamber 3b, and the oxygen chamber 3c are arranged sequentially from bottom to top, and a tower cover 32 is provided on the top of the tower body 31.

[0020] The air chamber 3a of the first adsorber 3 is connected to the gas supply assembly 1 via the first air inlet pipe 5 and to the desorption assembly 2 via the first desorption pipe 6. A first air inlet valve 6151 is installed on the first air inlet pipe 5, and a first desorption valve is provided on the first desorption pipe 6. The oxygen chamber 3c of the first adsorber 3 is connected to the gas storage assembly 4 via the first air outlet pipe 7, and a first air outlet valve 71 is provided on the first air outlet pipe 7.

[0021] The air chamber 3a of the second adsorber 3' is connected to the gas supply assembly 1 via the second air inlet pipe 5' and to the desorption assembly 2 via the second desorption pipe 6'. A second air inlet valve 51' is installed on the second air inlet pipe 5', and a second desorption valve 61' is installed on the second desorption pipe 6'. The oxygen chamber 3c of the second adsorber 3' is connected to the gas storage assembly 4 via the second air outlet pipe 7', and a second air outlet valve 71' is installed on the second air outlet pipe 7'.

[0022] In addition, the second end of the first adsorber 3 is connected to the second end of the second adsorber 3' through the pressure equalization pipe 8, and the pressure equalization pipe 8 is equipped with a pressure equalization valve 81.

[0023] In this embodiment, the air supply assembly 1 includes a blower 11 and an air filter 12. The outlet of the blower 11 is connected to the first air inlet pipe 5 and the second air inlet pipe 5'. The inlet of the blower 11 is connected to the air filter 12.

[0024] The desorption assembly 2 includes a vacuum pump 21 and a silencer 22. The inlet of the vacuum pump 21 is connected to the first desorption tube 6 and the second desorption tube 6'. The outlet of the vacuum pump 21 is connected to the silencer 22.

[0025] The gas storage assembly 4 includes a buffer tank 41, an oxygen booster 42, and a gas storage tank 43. The inlet of the buffer tank 41 is connected to the first outlet pipe 7 and the second outlet pipe 7'. The outlet of the buffer tank 41 is connected to the inlet of the oxygen booster 42. The outlet of the oxygen booster 42 is connected to the inlet of the gas storage tank 43.

[0026] This embodiment achieves continuous oxygen production by using two adsorbers to alternately adsorb and regenerate, thus improving work efficiency.

[0027] Specifically, when the first adsorber 3 is connected to the gas supply assembly 1 and the gas storage assembly 4 for adsorption and oxygen production, the second adsorber 3' is connected to the desorption assembly 2 for desorption and regeneration. After adsorption and desorption are completed, the first adsorber 3 is connected to the desorption assembly 2 for desorption and regeneration, and the second adsorber 3' is connected to the gas supply assembly 1 and the gas storage assembly 4 for adsorption and oxygen production. This process is repeated cyclically to achieve uninterrupted alternating oxygen production.

[0028] In addition, in this embodiment, the oxygen chambers 3c of the two adsorbers are connected by the equalizing pipe 8. When adsorption is complete, a portion of the high-pressure gas in the adsorber that has completed adsorption is sent to the other adsorber, so that the pressure in the two adsorbers is equalized. This not only recovers the energy of the high-pressure gas in the adsorber that has completed adsorption, but also recovers the high-concentration oxygen in the oxygen chamber 3c of the adsorber. This reduces the energy consumption of the pressure swing adsorption oxygen generator and the exhaust volume of the required blower 11, and improves the oxygen recovery rate.

[0029] Example 2 The difference between this embodiment and Embodiment 1 is that a porous partition 36 is provided below the first grid 33, and a first ceramic bead layer 37 is filled between the first grid 33 and the porous partition 36.

[0030] A second ceramic bead layer 38 is placed on top of the second grille 34, and the top of the second ceramic bead layer 38 is flush with the top of the tower body 31.

[0031] In this embodiment, by setting the first ceramic bead layer 37 and the second ceramic bead layer 38, the volume of the air cavity 3a and the oxygen cavity 3c can be reduced, the amount of unrecoverable gas residue in the air cavity 3a and the oxygen cavity 3c can be reduced, and the oxygen recovery rate can be further improved.

[0032] In addition, due to the thin air at high altitudes, the adsorption efficiency of molecular sieve 35 is reduced. The first ceramic bead layer 37 and the second ceramic bead layer 38 apply pressure to the molecular sieve 35 from the top and bottom sides, which can reduce the bed gap of molecular sieve 35 and improve the adsorption efficiency of molecular sieve 35.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
