Description

Technical Field

[0001] The utility model relates to the technical field of VPSA oxygen production, in particular to a novel VPSA oxygen production adsorber. Background Technique

[0002] VPSA oxygen production technology, the full name is vacuum pressure swing adsorption technology, uses molecular sieve as an adsorbent, and under the alternating action of vacuum and pressure, selectively adsorbs nitrogen in the air, so as to separate high-purity oxygen. VPSA oxygen production technology is widely used in medical, chemical, electronic, food and other fields to provide people with high-purity oxygen.

[0003] For the existing VPSA oxygen production adsorber, air is usually compressed and then introduced into the adsorption cylinder, and the molecular sieve in the adsorption cylinder is used to adsorb nitrogen in the air to separate oxygen and nitrogen in the air. However, most of the existing VPSA oxygen production adsorbers can only intake air in a single direction, resulting in a low intake rate. At the same time, it is difficult for air to come into uniform contact with the molecular sieve, resulting in low utilization rate of the molecular sieve, and thus low oxygen production efficiency.

[0004] Therefore, a novel VPSA oxygen production adsorber is now developed, which can intake air from both the upper and lower directions simultaneously, improve the intake rate, and enable the molecular sieve to come into uniform contact with air, thereby improving the oxygen production efficiency. Content of the Utility Model

[0005] In order to overcome the shortcomings that most of the existing VPSA oxygen production adsorbers can only intake air in a single direction, resulting in a low intake rate, and at the same time, it is difficult for air to come into uniform contact with the molecular sieve, resulting in low utilization rate of the molecular sieve and thus low oxygen production efficiency, the utility model provides a novel VPSA oxygen production adsorber that can intake air from both the upper and lower directions simultaneously, improve the intake rate, and enable the molecular sieve to come into uniform contact with air, thereby improving the oxygen production efficiency.

[0006] Technical Solution: A novel VPSA oxygen production adsorber includes a cylinder body, a lower head, a lower inlet pipe, an outlet pipe and an adsorption assembly. The lower side of the cylinder body is connected with the lower head, the lower side of the middle part of the lower head is connected with the lower inlet pipe, the right side of the cylinder body is connected with the outlet pipe, and an adsorption assembly capable of adsorbing and producing oxygen is arranged in the cylinder body.

[0007] In addition, particularly preferably, it further includes legs, and a plurality of legs are connected to the lower side of the lower head to improve the stability of the cylinder body during oxygen production.

[0008] In addition, particularly preferably, the adsorption assembly includes a blocking net plate, an inner cylinder, an upper head and an upper inlet pipe. The inner sides of the upper and lower parts of the cylinder body are connected with the blocking net plate, the inner cylinder is connected between the blocking net plates, the inner cylinder is connected with the cylinder body, the upper side of the cylinder body is connected with the upper head, and the upper side of the upper head is connected with the upper inlet pipe.

[0009] In addition, it is particularly preferred that the blocking mesh plate is provided with uniformly sized meshes, which can block the molecular sieve while not affecting the air flow.

[0010] In addition, it is particularly preferred that the inner cylinder is uniformly filled with molecular sieve.

[0011] In addition, it is particularly preferred that both the lower air inlet pipe and the upper air inlet pipe are provided with flange plates for easy docking.

[0012] In the present utility model, by allowing air to enter the cylinder from the lower air inlet pipe and the upper air inlet pipe respectively, the air intake rate is increased, and the molecular sieve and the gas can be made more fully and uniformly distributed. It achieves the effect of a new type of VPSA oxygen production adsorber that can intake air simultaneously from the upper and lower directions, increase the intake rate, and enable the molecular sieve to contact the air evenly, thereby improving the oxygen production efficiency.

[0016] The present utility model will be further described below with reference to the drawings and embodiments.

[0017] A new type of VPSA oxygen production adsorber, as Figure 1 and Figure 2 shown, includes a cylinder 1, a lower head 2, a lower air inlet pipe 3, an outlet pipe 4, support legs 5 and an adsorption assembly. The lower side of the cylinder 1 is connected to the lower head 2, the lower side of the middle part of the lower head is connected to the lower air inlet pipe 3, the right side of the cylinder 1 is connected to the outlet pipe 4, and three support legs 5 are connected to the lower side of the lower head 2 to improve the stability of the cylinder 1 during oxygen production. An adsorption assembly is provided inside the cylinder 1.

[0018] As Figure 1 and Figure 2As shown in the figure, the adsorption assembly includes a blocking net plate 6, an inner cylinder 7, an upper head 8, and an upper air inlet pipe 9. The inner sides of the upper and lower parts of the cylinder body 1 are connected with the blocking net plate 6. The inner cylinder 7 is connected between the blocking net plates 6. The inner cylinder 7 is connected with the cylinder body 1. The upper side of the cylinder body 1 is connected with the upper head 8. The upper side of the upper head 8 is connected with the upper air inlet pipe 9. The blocking net plate 6 is provided with uniformly sized mesh holes, which can block the molecular sieve while not affecting the air flow. The inner cylinder 7 is uniformly filled with molecular sieve inside. Both the lower air inlet pipe 3 and the upper air inlet pipe 9 are provided with flange plates for easy docking.

[0019] When using the present utility model, first move the cylinder body 1 to the VPSA oxygen generation area, support the cylinder body 1 through the legs 5 to ensure the stability of the cylinder body 1 during oxygen generation. Both the lower head 2 and the upper head 8 are matched with the whole body to ensure the airtightness of the cylinder body 1. Then dock the lower air inlet pipe 3 and the upper air inlet pipe 9 with the air supply pipeline. After the docking is completed, ventilate the lower air inlet pipe 3 and the upper air inlet pipe through the air supply pipeline, so that air enters the cylinder body 1 from the lower air inlet pipe 3 and the upper air inlet pipe respectively, thereby improving the air intake rate and accelerating the oxygen generation efficiency. After the air enters the cylinder body 1, it passes through the blocking net plate 6 and enters the inner cylinder 7. After passing through the molecular sieve in the inner cylinder 7, the molecular sieve adsorbs the nitrogen and other impurities in the air. And the gas enters the adsorber from both the upper and lower directions at the same time, which can make the molecular sieve and the gas contact more fully. Thus, it plays the role of a new type of VPSA oxygen generation adsorber that can intake air from both the upper and lower directions simultaneously, improve the intake rate, and make the molecular sieve and the air contact evenly to improve the oxygen generation efficiency. After the adsorption is completed, the remaining oxygen in the air is discharged and collected from the outlet pipe 4, and the oxygen generation process is completed.
