Description

Technical Field

[0001] This utility model relates to the field of gas preparation, specifically to an adsorption tower and a gas preparation device. Background Technology

[0002] Existing gas preparation equipment includes an inlet component, an adsorption component, a tail gas component, and a finished gas component. The inlet component provides feed gas to the adsorption component, which adsorbs specific gases within the feed gas and generates staggered tail gas and finished gas, thereby producing the finished gas. Since the finished gas production capacity of the gas preparation equipment is related to the volume of the adsorption tower, manufacturers need to customize the adsorption tower according to order requirements, leading to increased production cycles, impacting production efficiency, and preventing pre-production.

[0003] In addition, existing gas preparation devices include a set of adsorption components to enable a constant output of finished gas. During use, the gas preparation device will start and stop according to the consumption of finished gas. However, when the gas preparation device is restarted, it needs to be preheated for a long time to ensure that the concentration of prepared gas meets the requirements of finished gas. This not only makes it impossible to replenish finished gas in time due to the long preheating time, but also increases energy consumption and affects service life under frequent opening and closing conditions. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an adsorption tower and a gas preparation device. By assembling modular tubes with a base and a top cover to form an adsorption tower, the volume of the adsorption tower can be adjusted as needed, and the components can be pre-produced for convenient and rapid assembly.

[0005] This invention is achieved through the following method: an adsorption tower includes a tower body, which includes a base and a top cover disposed on the base. At least one modular tube is disposed between the base and the top cover, so that the base, modular tube, and top cover are vertically stacked and enclosed to form an adsorption cavity isolated from the outside. By using modular tubes to assemble with the base and top cover to form an adsorption tower, the number of modular tubes can be adjusted as needed to change the volume of the adsorption tower to meet usage requirements. Furthermore, the modular tubes, base, and top cover can be pre-produced for rapid assembly according to order requirements, effectively improving the user experience.

[0006] Preferably, the corresponding surfaces of the module tube and the base, as well as the corresponding surfaces of the module tube and the top cover, are sealed and connected by flange assemblies. Assembling the corresponding surfaces of adjacent components using flange assemblies facilitates disassembly and assembly, improves assembly efficiency, and enhances connection sealing, ensuring that the adsorption chamber of the adsorption tower is isolated from the outside environment.

[0007] Preferably, there are at least two modular tubes, and the corresponding surfaces of adjacent modular tubes are sealed together by a flange assembly. Assembling the modular tubes using flange assemblies facilitates disassembly and assembly, improves assembly efficiency, and enhances connection sealing, ensuring that the adsorption chamber of the adsorption tower is isolated from the outside environment.

[0008] Preferably, the flange assembly includes separate flange rings that abut against each other and are sealed and locked together by fasteners. The flange rings abutting against each other and being secured together by fasteners ensure a sealed connection between the flange rings. A sealing ring can be provided between corresponding flange rings to ensure a tight seal.

[0009] Preferably, the periphery of the end face of the module tube, the top surface of the base, and the bottom surface of the top cover extends outward to form the flange ring. The flange rings on the module tube, the base, and the top cover are all integrally machined, ensuring both sealing at the joint and improving connection strength.

[0010] Preferably, the module tube, base, and top cover have the same diameter, ensuring that the three are stacked together to form a cylindrical adsorption tower, thereby making the adsorption chamber of the adsorption tower cylindrical, which facilitates the removal and placement of molecular sieves for adsorbing gas.

[0011] Preferably, the volume of the inner cavity of the module tube is A, where A < 30L. This not only improves the volume adjustment accuracy of the adsorption chamber of the adsorption tower by reducing the volume of a single module tube, but also reduces the number of module tubes to be assembled and improves assembly efficiency by increasing the volume of a single module tube.

[0012] A gas preparation apparatus includes adsorption components, at least two groups of which each adsorption component comprises two adsorption towers. Each adsorption component can be independently turned on and off to adjust the gas production output. The two adsorption towers within the same group of adsorption components operate alternately. Adsorption components in different groups are independently controlled to adapt to the current demand for finished gas. This allows for adjustable finished gas production output, ensuring the apparatus meets the demand for finished gas while avoiding frequent on / off switching, eliminating the need for preheating, reducing energy consumption, and improving the user experience.

[0013] Preferably, the adsorption components are arranged in four groups, which ensures that the gas preparation device can operate with multi-stage finished gas production and also effectively simplifies the structure by limiting the number of groups. The adsorption components are arranged in parallel with each other, and each adsorption component shares the inlet component, the exhaust gas component, and the finished gas component.

[0014] Preferably, the gas preparation device includes an inlet component, an exhaust gas component, and a finished gas component. The inlet component provides raw material gas to the adsorption components, and the exhaust gas and finished gas discharged from the adsorption components are treated by the exhaust gas component and the finished gas component, respectively. The inlet component, exhaust gas component, and finished gas component work in conjunction with each adsorption component to not only meet the usage requirements of the adsorption components but also to adjust the efficiency according to the number of adsorption components in operation, ensuring the smooth operation of the gas preparation device.

[0015] The beneficial effects of this invention are as follows: By using modular tubes to assemble with the base and top cover to form an adsorption tower, the number of modular tubes can be adjusted as needed to control the volume of the adsorption tower and meet usage requirements. Furthermore, the modular tubes, base, and top cover can be pre-produced for rapid assembly according to order requirements, effectively improving the user experience. In addition, the two adsorption towers within the same adsorption assembly group operate alternately, and the adsorption assemblies in different groups are independently controlled to adapt to the current finished gas consumption demand. This makes the finished gas output of the gas preparation device adjustable, ensuring that the gas preparation device can meet the finished gas usage demand while avoiding frequent switching between on and off, eliminating the need for preheating, reducing energy consumption, and improving the user experience.

[0019] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] This embodiment provides an adsorption tower.

[0022] like Figure 1 The illustrated adsorption tower comprises a tower body, which includes a base 1 and a top cover 2 mounted on the base 1. At least one modular tube 3 is disposed between the base 1 and the top cover 2, allowing the base 1, modular tube 3, and top cover 2 to be vertically stacked and enclosed to form an adsorption cavity isolated from the outside environment. By using modular tubes 3 to assemble with the base 1 and top cover 2 to form the adsorption tower, the number of modular tubes 3 can be adjusted as needed to control the tower volume and meet usage requirements. Furthermore, the modular tubes 3, base 1, and top cover 2 can be pre-produced, facilitating rapid assembly according to order requirements and effectively improving the user experience.

[0023] In this embodiment, the adsorption tower is assembled from a base 1, a module tube 3, and a top cover 2. The base 1 and the top cover 2 are basic components, and the module tube 3 is an adjustable component. The volume of the adsorption chamber of the adsorption tower can be adjusted by increasing or decreasing the number of module tubes 3. This ensures that the structure of the adsorption tower meets the usage requirements and also allows for convenient and rapid assembly by pre-producing various components, thereby improving the user experience.

[0024] In this embodiment, the base 1 and the top cover 2 can be freely matched with the module tube 3, thereby adjusting the volume of the adsorption chamber of the adsorption tower, including but not limited to the following structures:

[0025] Structure 1: The base 1 and the top cover 2 are directly connected, without the module tube 3, so that the adsorption chamber of the adsorption tower has the minimum basic volume.

[0026] Structure 2: A modular tube 3 is installed between the base 1 and the top cover 2;

[0027] Structure 3: Two modular tubes 3 are installed between the base 1 and the top cover 2.

[0028] Adjusting the number of module tubes 3 on the adsorption tower to change the volume of the adsorption chamber and thus meet the usage requirements should be considered as a specific implementation method of this embodiment.

[0029] In this embodiment, the corresponding surfaces of the module tube 3 and the base 1, the corresponding surfaces of the module tube 3 and the top cover 2, and the corresponding surfaces of adjacent module tubes 3 are all sealed and connected by flange assemblies. This facilitates quick assembly and ensures the sealing of the connection, effectively isolating the adsorption chamber of the adsorption tower from the outside world.

[0030] In this embodiment, the flange assembly includes separate flange rings 4, which abut against each other and are sealed and locked together by fasteners. Specifically, the flange rings 4 are formed by extending outwards from the periphery of the end face of the module tube 3, the top surface of the base 1, and the bottom surface of the top cover 2. Each flange ring 4 has a flat end face with the same contour and size. The flange ring 4 is provided with mounting holes equidistantly spaced along its circumference. When the end faces of the flange rings 4 are tightly fitted together, they are aligned with the corresponding mounting holes so that fasteners pass through the mounting holes and are screwed in to lock the flange rings together, ensuring a sealed fit. To improve sealing reliability, a sealing ring is sandwiched between the corresponding flange rings 4, thereby enhancing the sealing effect.

[0031] In this embodiment, the module tube 3, base 1, and top cover 2 have the same diameter, and the inner wall diameters of the inner membrane tube, base 1, and top cover 2 are also the same, so that the adsorption tower has a cylindrical adsorption cavity, which improves the pressure resistance, facilitates the handling of molecular sieves, and enhances the user experience. A cylindrical lower cavity is formed by a recess in the center of the top surface of the base 1, and a cylindrical upper cavity is formed by a recess in the center of the bottom surface of the top cover 2, so that when the base 1 and top cover 2 are directly connected, they can enclose an adsorption cavity with the smallest possible volume.

[0032] In this embodiment, the volume of the inner cavity of the module tube 3 is A, where A < 30L. This not only effectively improves the volume adjustment accuracy of the adsorption chamber of the adsorption tower when adding or removing module tubes 3, but also effectively reduces the number of module tubes 3 to be adjusted, thus facilitating disassembly and assembly.

[0033] Example 2:

[0034] Compared to Embodiment 1, this embodiment provides a gas preparation apparatus.

[0035] like Figure 2 The illustrated gas preparation device comprises adsorption components 5, of which there are at least two groups. Each adsorption component 5 includes two adsorption towers 6. Each adsorption component 5 can be independently opened and closed to adjust the gas production output. The two adsorption towers within the same group of adsorption components 5 operate alternately. Adsorption components 5 in different groups are independently opened and closed to adapt to the current demand for finished gas. This makes the finished gas output of the gas preparation device adjustable, ensuring that the gas preparation device can meet the demand for finished gas while avoiding frequent opening and closing switching, eliminating the need for preheating, reducing energy consumption, and improving the user experience.

[0036] In this embodiment, the output of the finished gas from the gas preparation device is correlated with the number of operating adsorption components 5. There are four groups of adsorption components 5, and each group can be independently controlled to open and close, allowing for multi-level adjustment of the operating power of the gas preparation device. This ensures that the output of the finished gas meets usage requirements while eliminating the need for frequent start-ups and shutdowns, thus improving work efficiency. Specifically:

[0037] When all four adsorption components 5 are running simultaneously, the gas preparation device operates at full load, and the output of finished gas can reach 100% of the rated output.

[0038] When the three adsorption components 5 are running simultaneously, the gas preparation device operates at full load, and the output of finished gas can reach 75% of the rated output.

[0039] When the two adsorption components 5 are running simultaneously, the gas preparation device operates at full load, and the output of finished gas can reach 50% of the rated output.

[0040] When a set of adsorption components 5 are running simultaneously, the gas preparation device operates at full load, and the output of finished gas can reach 25% of the rated output.

[0041] The number of adsorption components 5 can be adjusted according to needs and adjustment precision, and all of these should be considered as specific implementation methods of this embodiment.

[0042] In this embodiment, the gas preparation device includes an inlet assembly, an exhaust gas assembly, and a finished gas assembly. The inlet assembly provides raw material gas to the adsorption assembly 5, and the exhaust gas and finished gas discharged from the adsorption assembly 5 are treated by the exhaust gas assembly and the finished gas assembly, respectively. The adsorption assemblies 5 are arranged in parallel to each other to ensure that each group of adsorption assemblies 5 can be directly used in conjunction with the inlet assembly, the exhaust gas assembly, and the finished gas assembly.

[0043] In this embodiment, the gas preparation device may be an oxygen generator, a nitrogen generator, etc., and all of these should be considered as specific implementations of this embodiment.

[0044] The structure and effect of the adsorption tower described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
