DETAILED DESCRIPTION

[0028] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0029] This embodiment discloses a novel integrated oxygen production and supply shelter, comprising a standard 6058mm-long shelter with an expansion compartment, oxygen production system equipment, gas piping, electrical system, and auxiliary equipment. The expansion compartment includes an oxygen inhalation terminal, lighting, heating vents, and folding seats. The electrical system includes a power distribution cabinet, external power supply ports, and an in-cabin lighting system.

[0030] A separate compartment, 1398mm deep, is located at the rear of the shelter. A diesel generator set is housed within it. The generator set's air intake grille is located beneath the double doors at the rear of the compartment. The sides of the compartment are equipped with an air intake fan, utility power connection port, fuel filling port, nitrogen exhaust port, generator set smoke exhaust port, and generator set exhaust grille. Auxiliary equipment includes a shelter leveling mechanism, a ladder, and a fire extinguisher. The leveling mechanism is installed at the lower corners of the front and rear sides of the shelter.

[0031] The outside of the shelter Figure 1 、 Figure 2 、 Figure 3 shown. Figure 1 This is the left side view of the exterior of the oxygen production cabin. Figure 2 The left side of the center is the external rear view of the oxygen production cabin. Figure 2 The middle right side is the front view of the oxygen production cabin. Figure 3 This is the right side of the exterior of the oxygen production cabin. The cabin is divided into four parts: the oxygen production room, the bottle filling room, the expansion compartment, and the generator compartment.

[0032] The oxygen production equipment is located within the oxygen production room and includes the air compressor, refrigeration and drying unit No. 1 23, the air compressor, refrigeration and drying unit No. 1 25, the air buffer tank 22, the oxygen buffer tank 28, the oxygen generator 26, the carbon fiber oxygen storage tank 24, and the oxygen compressor 29. The oxygen generator 26 is located at the rear of the oxygen production room, while the oxygen compressor 29, air buffer tank 22, and oxygen buffer tank 28 are located in the middle. Four sets of filters are installed between the air buffer tank 22 and the oxygen generator 26.

[0033] The air buffer tank 22 and the oxygen buffer tank 28 have dimensions of 550 mm in diameter and 1545 mm in diameter. The air buffer tank 22 and the oxygen buffer tank 28 are fixed vertically to the bottom plate of the cabin.

[0034] The filling room houses two 40L oxygen cylinders 30 at the rear, with a filling bus 32 located above the cylinders. Nine 2L oxygen cylinders 33 are located on the right side. The left side houses connections for external oxygen supply lines and a low-pressure oxygen bag filling port, and a foldable oxygen cart 31 is located at the lower left side.

[0035] The bottle filling bus 32 is provided with 4 bottle filling interfaces, thereby enabling a maximum of 4 oxygen cylinders to be filled at the same time.

[0036] The carbon fiber oxygen storage tank 24 is horizontally fixed on the top wall of the oxygen production chamber.

[0037] The expansion cabin described in this embodiment is located on the right side of the cabin. A 27-cabin oxygen inhalation terminal, an information display and control terminal, and a warm air inlet are installed on the partition between the expansion cabin and the oxygen production room. An explosion-proof light is installed on the top of the expansion cabin.

[0038] The generator compartment described in this embodiment is located at the rear of the cabin and is used to house a diesel generator set 20. A generator compartment maintenance door 9 is located at the rear of the compartment. A generator installation and maintenance door 8 is located on the left side of the compartment. A nitrogen exhaust grille 4 is located at the top of the left side of the compartment. An active air intake grille 15 is located on the upper right side of the compartment. An air scoop installed inside the compartment draws fresh air from outside into the oxygen production chamber, ensuring proper air circulation. A mains power input port 18 and a fuel filling port 19 are located on the lower right side of the compartment.

[0039] A fuel heater is installed on the generator support, and warm air is introduced into the oxygen production room and expansion cabin through air ducts. When the external environment of the cabin is cold, the warm air generated by the fuel heater heats the oxygen production unit and expansion cabin.

[0040] Explosion-proof lighting is installed in the oxygen production room, bottle filling room, expansion cabin, and generator compartment to illuminate the cabin.

[0041] This embodiment also discloses a method for high-efficiency oxygen production at high altitudes using the oxygen production equipment. The oxygen production system uses clean air as the raw material for oxygen production and a zeolite molecular sieve as the adsorbent. Compressed air utilizes the molecular sieve's varying adsorption capacities for nitrogen and oxygen at different pressures. Nitrogen, water, carbon dioxide, and other components are adsorbed on the molecular sieve's surface, while unadsorbed oxygen is collected at the outlet and becomes product gas.

[0042] The adsorbent utilizes a medical-grade, small-particle sodium-lithium hybrid molecular sieve, offering excellent adsorption efficiency and high oxygen output concentration. Utilizing the principle of pressurized adsorption and reduced-pressure desorption, oxygen can be separated from air at room temperature. Pressure swing adsorption (PSA) achieves nitrogen and oxygen separation, adsorbing nitrogen from the air and releasing oxygen, thereby separating the oxygen. PSA oxygen production utilizes the selective adsorption properties of molecular sieves, employing a cycle of pressurized adsorption and reduced-pressure desorption, allowing compressed air to alternately enter the adsorption tower to achieve air separation, resulting in the continuous production of high-purity oxygen.

[0043] The oxygen generator consists of eight adsorption towers, divided into two groups. These two groups alternate between adsorption and regeneration, producing oxygen with a stable flow rate and purity. Switching between the two adsorbers is automatically accomplished by a programmable valve controlled by a PLC.

[0044] Key points of the present invention

[0045] 1. Following the design principles of miniaturization, lightweight, and modularization, through reasonable layout and effective utilization of cabin space, large-flow oxygen production equipment and large-capacity oxygen storage equipment are installed in the cabin.

[0046] 2. Expand cabin design and implementation.

[0047] 3. The cabin is integrated with a diesel generator set to achieve self-generation and emergency power supply functions.

[0048] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, it is apparent to those skilled in the art that several variations and improvements may be made without departing from the principles of the present invention, and these should also be considered to fall within the scope of protection of the present invention.
