Technical Field
[0001] The utility model relates to the technical field of oxygen production equipment, in particular to a lower air inlet system of a molecular sieve oxygen production system. Background Art
[0002] Molecular sieve oxygen generator is an oxygen production equipment that uses control to produce high-purity oxygen. It obtains oxygen by passing air through high pressure, filtering, and then transporting it to an adsorption tower to remove nitrogen, carbon dioxide and other air components. In existing oxygen production systems, molecular sieve oxygen generators and their matching air treatment mechanisms, such as air compressors, cooling systems, gas tanks, filters, etc., are usually laid flat on a mounting table or bottom surface, making the entire oxygen production system large in size, occupying a large area, and not easy to move and transport, and inconvenient to use. In addition, in order to solve the heat generated by the operation of various mechanisms and the heat generated by air compression in existing oxygen production systems, cooling fans are usually added to the oxygen production system to make the wind blow from one side of the system to the other side to take away the heat. However, this method does not fully utilize the principle that hot air rises and cold air falls to fully utilize the temperature of the air itself, and is not the best method.
[0003] In order to make the molecular sieve oxygen generator more convenient to use, the inventor has designed a compact oxygen production system, which effectively reduces the volume of the oxygen production system by integrating compression, cooling, gas storage, oxygen production and other mechanisms together, and through reasonable space utilization and layout. At the same time, the inventor has designed a down-air intake system for this oxygen production system. Utility Model Content
[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a lower air inlet system of a molecular sieve oxygen production system.
[0005] The technical solution of this utility model is as follows:
[0006] A lower air inlet system of a molecular sieve oxygen production system is applied to a compactly arranged oxygen production system, wherein the oxygen production system comprises a box body, wherein the box body is divided into an oxygen production area located on one side of the box body and a gas storage area and an air treatment area on the other side, wherein the gas storage area is located below the air treatment area;
[0007] The gas storage area is isolated from the air processing area and the oxygen production area, and an air source inlet is provided at the bottom, and an air compressor air inlet is provided on the top partition, so that air can enter the air compressor air inlet from the air source inlet;
[0008] The oxygen production area is connected with the air processing area, a cooling air inlet is arranged at the bottom, and a cooling air outlet is arranged at the top of the air processing area. Air can enter the box from the cooling air inlet and be discharged from the cooling air outlet.
[0009] Among them, an air compressor is arranged in the air processing area, and its air inlet end is connected with the air inlet hole of the air compressor through a pipeline.
[0010] The air storage area is equipped with an air tank that can store the high-pressure air compressed by the air compressor.
[0011] A molecular sieve oxygen generator is provided in the oxygen production area, and its air inlet end is connected to the gas storage tank.
[0012] When the oxygen production system is in use, both the molecular sieve oxygen generator and the air compressor will generate heat, so it is necessary to cool the molecular sieve oxygen generator, air compressor and other mechanisms to ensure the normal operation of these mechanisms.
[0013] The oxygen production system of the present application is provided with a cooling air inlet at the bottom of the oxygen production area, and the low temperature of the low-level air is used to make the air entering the oxygen production area low-temperature air to cool the molecular sieve oxygen generator. In addition, the molecular sieve oxygen generator will also discharge low-temperature nitrogen while producing oxygen, and the low-temperature nitrogen will flow to the air treatment area together with the low-temperature air to cool the air treatment mechanism such as the air compressor, and then be discharged from the cooling air outlet.
[0014] In addition, the temperature of the high-pressure air compressed by the air compressor will rise, forming high-temperature and high-pressure air, which will cause the temperature of the gas tank to rise, and it needs to be cooled to avoid equipment damage. To this end, the oxygen production system of the present application opens the air compressor's wind channel in the gas storage area, and the air source inlet is opened at the bottom of the gas storage area, so that the air entering the gas storage area is low-temperature air, and it will pass through the outside of the gas tank when flowing to the air inlet of the air compressor, which has a cooling effect on the gas tank. In addition, the air source of the air compressor directly uses low-temperature air at a low position, which can also reduce the temperature of the compressed air to a certain extent.
[0015] The bottom air intake system of the present application opens the air inlet at the bottom of the box, and uses low-temperature air at a low position for cooling, which can achieve a better cooling effect.
[0016] Specifically, the air source inlet is arranged close to the side wall of one side of the box body, and correspondingly, the air compressor air inlet is located at an end of the partition away from the air source inlet.
[0017] This allows the air to flow longer to cool the tank.
[0018] More specifically, the air source inlet extends along the width direction of the box body to the front and rear walls of the box body.
[0019] The cooling air inlet of the present application specifically includes multiple cooling air inlets, which are respectively arranged close to the front and rear walls of the box body.
[0020] The molecular sieve oxygen generator is located between multiple cooling air inlets so that the air entering from the cooling air inlets can fully cool the molecular sieve oxygen generator and take away the low-temperature nitrogen generated by the molecular sieve oxygen generator.
[0021] An exhaust fan is provided at the cooling air outlet of the present application to provide power for the cooling air flow in the oxygen production area and the air treatment area, and the temperature inside the box can also be regulated by frequency conversion.
[0022] The utility model provides a lower air inlet system of a molecular sieve oxygen production system, which utilizes low-temperature air at a low position to cool the oxygen production system, thereby achieving a better cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a lower air intake system of a molecular sieve oxygen production system, which is applied to a compactly arranged oxygen production system. The oxygen production system includes a box body 1, and the box body 1 is divided by a partition 11 into an oxygen production area 2 located on one side of the box body 1 and a gas storage area 3 and an air treatment area 4 on the other side. The gas storage area 3 is located below the air treatment area 4.
[0029] The gas storage area 3 is isolated from the air treatment area 4 and the oxygen production area 2, and an air source inlet 31 is provided at the bottom thereof, and an air compressor air inlet hole 32 is provided at the top partition 11. An air compressor 41 is provided in the air treatment area 4 on the top of the partition 11 to provide high-pressure air for the molecular sieve oxygen generator 21. The air inlet end of the air compressor 41 is sealedly connected to the air compressor air inlet hole 32 on the partition 11 through a pipeline. Air can flow from the air source inlet 31 through the gas storage area 3 and then enter the air compressor 41 from the air compressor air inlet hole 32 as an air source.
[0030] A plurality of gas storage tanks 33 are disposed transversely in the gas storage area 3 to reduce the overall height of the oxygen production system. The gas storage tanks 33 are connected to the air compressor 41, and the high-pressure air compressed by the air compressor 41 enters the gas storage tanks 33 for storage. Preferably, the gas storage tanks 33 include two.
[0031] The gas storage tank 33 is also connected to the air inlet end of the molecular sieve oxygen generator 21 to supply high-pressure air to the molecular sieve oxygen generator 21 for oxygen production. The molecular sieve oxygen generator 21 is erected in the oxygen production area 2, and the oxygen production area 2 is connected to the air processing area 4. A cooling air inlet 22 is provided at the bottom of the molecular sieve oxygen generator 21, and a cooling air outlet 42 is provided at the top of the air processing area 4. Air can enter the box 1 from the cooling air inlet 22 and be discharged from the cooling air outlet 42.
[0032] When the oxygen production system is in use, both the molecular sieve oxygen generator 21 and the air compressor 41 will generate heat, so it is necessary to cool the molecular sieve oxygen generator 21 and the air compressor 41 to ensure the normal operation of these mechanisms.
[0033] The oxygen production system of the present application is provided with a cooling air inlet 22 at the bottom of the oxygen production area 2, and the air entering the oxygen production area 2 is low-temperature air by utilizing the low temperature characteristic of low-level air, so as to cool the molecular sieve oxygen generator 21. In addition, the molecular sieve oxygen generator 21 will also discharge low-temperature nitrogen while producing oxygen, and the low-temperature nitrogen will flow to the air processing area 4 together with the low-temperature air, cool the air processing mechanism such as the air compressor 41, and then be discharged from the cooling air outlet 42.
[0034] In addition, the temperature of the high-pressure air compressed by the air compressor 41 will rise, forming high-temperature and high-pressure air, which will cause the temperature of the gas tank 33 to rise, so it needs to be cooled to avoid equipment damage. To this end, the oxygen production system of the present application opens the air inlet channel of the air compressor 41 in the gas storage area 3, and the air source inlet 31 is opened at the bottom of the gas storage area 3, so that the low-level low-temperature air enters the gas storage area 3 first, and passes through the outside of the gas tank 33 when flowing to the air compressor air inlet 32, which has a cooling effect on the gas tank 33. In addition, the air source of the air compressor 41 directly uses low-level low-temperature air, which can also reduce the temperature of the compressed air to a certain extent.
[0035] The lower air intake system of the present application opens the air inlet at the bottom of the box 1, and utilizes low-temperature air at a low position for cooling, which can achieve a better cooling effect.
[0036] Please refer to Figure 2 In this embodiment, the air source inlet 31 is arranged close to the side wall of the box body 1, and in order to allow the air to have a longer flow time to cool the air storage tank 33, the air compressor air inlet 32 is arranged at an end of the partition 11 away from the air source inlet 31, so that the air flows through the entire air storage tank 33 to cool it.
[0037] More specifically, the air source inlet 31 extends along the width direction of the box body 1 to the front and rear walls of the box body 1. It can be composed of mesh holes, or designed as a rectangular opening, and covered with a dense mesh to filter large particles of sand, dust, etc. to avoid damage to the air compressor 41.
[0038] The cooling air inlet 22 of the present application specifically includes multiple cooling air inlets 22, which are respectively arranged near the front and rear walls of the box body 1, and the molecular sieve oxygen generator 21 is preferably located between the multiple cooling air inlets 22, so that the air entering from the cooling air inlet 22 can fully cool the molecular sieve oxygen generator 21, and at the same time can take away the low-temperature nitrogen generated by the molecular sieve oxygen generator 21, so as to better cool the various mechanisms of the air treatment area 4.
[0039] The cooling air inlet 22 may also be composed of mesh holes, or designed as a rectangular opening and covered with a dense mesh.
[0040] An exhaust fan 43 is provided at the cooling air outlet 42 of the present application to provide power for the cooling air flow in the oxygen production area 2 and the air treatment area 4, and at the same time, the temperature in the box 1 can be regulated by frequency conversion.
