Description

Technical Field

[0001] This application relates to the technical field of oxygen generation, and particularly to an oxygen generation device and an oxygen generation system. Background Art

[0002] The oxygen generation method of the adsorption tower is to use the molecular sieve inside to adsorb nitrogen in compressed air, thereby obtaining oxygen with a higher purity. In related technologies, most oxygen generation systems use double-tower oxygen generation equipment or single-tower oxygen generation equipment. However, the double-tower oxygen generation equipment has problems such as large floor area, many pipelines, and high costs. In the single-tower oxygen generation equipment, due to the stacking of molecular sieves, some molecular sieves are not in full contact with air, resulting in more molecular sieves being required to obtain the same amount of oxygen, and the utilization rate of the molecular sieves is relatively low. Summary of the Utility Model

[0031] In addition, if there appears the term "and / or", "and / or" is merely a correlative relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this text generally indicates that the associated objects before and after are in an "or" relationship. If there appear such terms as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0035] Referring to Figure 1 As shown, an embodiment of the present application provides an oxygen generation device 100, which can be used in various molecular sieve adsorption oxygen generation systems, such as VPSA (Vacuum Pressure Swing Adsorption) oxygen generation systems, PSA (Pressure Swing Absorption) oxygen generation systems, etc., which can reduce the occupied area of the equipment, reduce pipeline layout, reduce costs, and improve the utilization rate of molecular sieves.

[0036] Continuing to refer to Figure 2 and Figure 3 As shown, specifically, the oxygen generation device 100 includes a main body 110 and at least one first partition 120. Among them, the main body 110 is provided with a receiving cavity 114, and each first partition 120 is disposed inside the main body 110 and divides the receiving cavity 114 into at least two reaction chambers 1141 to fill molecular sieve materials in each reaction chamber 1141 for adsorption oxygen generation and oxygen supply. The main body 110 is also provided with at least two air outlets 115 and at least two air inlets 116, and each reaction chamber 1141 is communicated with a corresponding air outlet 115 and air inlet 116. The air inlet 116 is connected to an external air supply device to respectively introduce the treated air into the corresponding reaction chamber 1141. The molecular sieve in the reaction chamber 1141 can adsorb nitrogen in the air to provide high-concentration oxygen. In this way, each reaction chamber 1141 has a separate air inlet 116 and air outlet 115, and the individual operation of each reaction chamber 1141 can be realized, so as to reasonably set the number of reaction chambers 1141 required to work according to the demand of oxygen supply.

[0037] Exemplarily, the main body 110 has a cylindrical structure and can be made of stainless steel or carbon steel to meet the operating intensity of high-pressure gases. Each first partition 120 is arranged parallel to the axis of the main body 110, and the number of first partitions 120 can be one, two, three, four, etc., to correspondingly divide the receiving cavity 114 into two, three, four, five, etc. reaction chambers 1141. Correspondingly, the number of air outlets 115 and air inlets 116 is also two, three, four, five, etc.

[0038] In this specific embodiment, the number of the first partition plates 120 can be one. The first partition plates 120 are arranged in the middle of the main body 110 to divide the accommodation cavity 114 into two reaction chambers 1141 of the same size. During the operation process, according to the oxygen supply demand, the two reaction chambers 1141 can operate simultaneously or alternately to realize various operation modes. When controlling the operation state of the reaction chambers 1141, it only needs to pause the air supply of the corresponding air inlet 116 through the valve, and the operation is simple and convenient.

[0039] It can be understood that by integrating multiple reaction chambers 1141 inside one main body 110, compared with the double-tower oxygen generation device 100 in the related art, the installation occupation area is reduced, the pipeline layout is reduced, and the operation cost is reduced. At the same time, compared with the single-tower oxygen generation device 100, when the same amount of oxygen needs to be prepared, the molecular sieves are distributed in the two reaction chambers 1141, the stacking and extrusion degree of the molecular sieves is reduced, the contact between the molecular sieves and the air is more sufficient, and the utilization rate of the molecular sieves is improved.

[0040] In some embodiments, the main body 110 includes a main shell 111, a bottom shell 112, and an air inlet plate 113. The main shell 111 and the bottom shell 112 are spliced and matched. The air inlet plate 113 is arranged at the connection of the main shell 111 and the bottom shell 112. The bottom shell 112 and the air inlet plate 113 define an air inlet chamber 117. The air inlet chamber 117 is communicated with each air inlet 116. The air inlet plate 113 is provided with a plurality of air inlet holes 1131 to communicate the air inlet chamber 117 and each reaction chamber 1141 through the air inlet holes 1131.

[0041] Specifically, the main shell 111 and the bottom shell 112 can be assembled by means of flange surface locking or hoop, etc. to realize the disassembly and assembly cooperation between the main shell 111 and the bottom shell 112, which is convenient for later maintenance. The air inlet plate 113 is fixedly arranged between the main shell 111 and the bottom shell 112 to separate the reaction chamber 1141 from the air inlet chamber 117. When the molecular sieve material is placed in the reaction chamber 1141, the air inlet plate 113 provides support for the molecular sieve. During the operation process, external air flows into the air inlet chamber 117 through the air inlet 116, and then enters the reaction chamber 1141 through the air inlet holes 1131 of the air inlet plate 113, and contacts each molecular sieve material from bottom to top. After the molecular sieve adsorbs the non-oxygen gas in the air, it outputs oxygen with a higher concentration to the air outlet 115.

[0042] Furthermore, the oxygen generation device 100 further includes at least one second partition plate 150. Each second partition plate 150 is arranged inside the bottom shell 112 and divides the air inlet chamber 117 into at least two sub-chambers 1171. Each sub-chamber 1171 is respectively communicated with a corresponding reaction chamber 1141 and an air inlet 116, so as to realize the separate air supply of each reaction chamber 1141. Only by pausing the air supply of the corresponding air inlet 116, the separate operation control of the corresponding reaction chamber 1141 can be realized.

[0043] Furthermore, the main body 110 further includes a top cover 118 which is connected to one end of the main housing 111 away from the bottom housing 112. The air outlet 115 is provided on the top cover 118 so that the gas is discharged upward, and during the flow process, the air contacts the molecular sieve material upward in sequence, improving the adsorption efficiency of the molecular sieve.

[0044] Specifically, flange surfaces are provided on both the outer sides of the top cover 118 and the main housing 111. During the assembly process, after the flange surfaces of the top cover 118 and the main housing 111 are fitted, bolts are used for locking. Preferably, sealing treatments are performed at the connection between the top cover 118 and the main housing 111 and at the connection between the main housing 111 and the bottom cover, such as coating a sealing member, setting a sealing retaining ring, etc., which are not specifically limited herein to meet the sealed working environment of the main body 110 and avoid gas leakage.

[0045] Furthermore, the main body 110 further includes an upper sealing plate which is arranged at the connection between the top cover 118 and the main housing 111 to define an accommodation cavity 114 with the main housing 111.

[0046] Specifically, the upper sealing plate is a flat plate member and can completely cover the top of the main housing 111 to seal the top of the accommodation cavity 114 and ensure the sealing operation of the reaction chamber 1141. The upper sealing plate can be directly welded and fixed to the main housing 111, or can be provided with a flange surface and directly locked with the main housing 111 and the top cover 118 by bolts, which are not specifically limited herein.

[0047] In some embodiments, the oxygen generation device 100 further includes at least two gas collecting pipes 130, and each gas collecting pipe 130 respectively passes through the corresponding air outlet 115.

[0048] Continue to refer to Figure 4 As shown, specifically, the gas collecting pipe 130 includes an air outlet part 131 and a gas collecting part 132. The air outlet part 131 passes through the air outlet 115 and one end is exposed outside the reaction chamber 1141 to output the oxygen generated by the reaction chamber 1141. The gas collecting part 132 is fixedly arranged at one end of the air outlet part 131 located in the reaction chamber 1141, and a plurality of gas collecting holes 133 are formed on the circumferential side of the gas collecting part 132 so that the oxygen in the reaction chamber 1141 enters the inside of the gas collecting pipe 130 through each gas collecting hole 133. Under the guiding and conveying of the gas collecting part 132, the oxygen converges in the gas collecting pipe 130 and is finally discharged through the air outlet part 131.

[0049] Furthermore, the inner diameter of the gas collecting part 132 is larger than that of the air outlet part 131, so as to facilitate the convergence of oxygen from the gas collecting part 132 into the air outlet part 131 and improve the output rate of oxygen.

[0050] Specifically, the gas collection part 132 is coaxially arranged with the gas outlet part 131, and the bottom surface of the gas collection part 132 is in a sealed state. The gas collection holes 133 are distributed in an array structure on the circumferential side of the gas collection part 132, so that oxygen can only enter from the gas collection holes 133 on the circumferential side, and oxygen in different directions can enter simultaneously, facilitating the convergence and discharge of oxygen.

[0051] Continue to refer to Figure 5 As shown, in some embodiments, the oxygen generation device 100 further includes a pressing assembly 140 and a screen. The screen is laid on one side of the intake plate 113 located in the reaction chamber 1141, and the pressing assembly 140 is used to fix the screen to the intake plate 113.

[0052] Specifically, the aperture of the screen (not shown in the figure) needs to be smaller than the particle size of the molecular sieve to prevent the molecular sieve from falling into the intake chamber 117 through the intake holes 1131 of the intake plate 113. After the screen is laid on the intake plate 113, the pressing assembly 140 fixes the screen and the intake plate 113 to prevent the screen from being displaced.

[0053] Continue to refer to Figure 6 As shown, in one embodiment, the pressing assembly 140 includes a pressure ring 141 and a locking member 142. The pressure ring 141 is circumferentially arranged on the side of the intake plate 113, and the locking member 142 is used to fix the pressure ring 141 to the intake plate 113.

[0054] Specifically, locking hole positions can be provided on both the pressure ring 141 and the side of the intake plate 113. The locking member 142 can be a bolt. After the locking hole positions of the pressure ring 141 and the intake plate 113 are aligned, the pressure ring 141 and the intake plate 113 are locked and fixed by bolts to limit and fix the screen.

[0055] In some other embodiments, the pressing assembly 140 can also be ceramic balls, cylinders, etc., as long as the screen can be pressed against the intake plate 113, and no specific limitation is made here.

[0056] In a second aspect, the embodiments of the present application further provide an oxygen generation system, including the oxygen generation device 100 in any of the above embodiments.

[0057] Specifically, the oxygen generation system can further include a gas supply device and a gas storage device. Among them, the gas supply device is connected to the intake port 116 of the oxygen generation device 100 through a pipeline to supply the air to be processed to the oxygen generation device 100. The gas storage device is connected to the outlet port 115 of the oxygen generation device 100 through a pipeline to store the generated high-concentration oxygen. Exemplarily, the gas supply device can be a blower or an air compressor, etc., and the gas storage device can be a gas storage tank or a gas storage cylinder, etc., which can be reasonably selected according to different operation modes, and no specific limitation is made here.

[0058] In this embodiment, there is the oxygen generation device 100 in any of the above embodiments. Therefore, it has all the beneficial effects of the oxygen generation device 100 in any of the above embodiments, and will not be elaborated here one by one.

[0059] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0060] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
