Description

Technical Field

[0001] The utility model relates to the technical field of atomizers, in particular to an oxygen-containing atomizer. Background Art

[0002] Nebulizers are widely used in medical, industrial and household fields. Their main function is to convert liquids into fine droplets to achieve specific application effects. However, the performance and efficiency of the nebulizer are often affected by the quality of the gas source. Therefore, improving the purity and stability of the gas source is one of the keys to improving the performance of the nebulizer. In the prior art, nebulizers usually separate oxygen and nitrogen in compressed air through molecular sieves, and use high-purity oxygen for atomization, while nitrogen is discharged as waste gas. However, the adsorption capacity of molecular sieves is limited and requires regular regeneration to maintain its separation efficiency. In addition, air filters will accumulate a large amount of dust and impurities during long-term use, resulting in a decrease in the filtering effect, and regular cleaning and maintenance are required.

[0003] How to solve the above technical problems is the subject faced by this utility model. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides an oxygen-containing atomizer which has a reasonable design, a simple structure, is safe and reliable, and can realize efficient regeneration of molecular sieves and automatic cleaning of air filters.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows: the utility model provides an oxygen-containing atomizer, including an atomizer body, an air filter, an air compressor and a molecular sieve;

[0007] The atomizer is connected to the molecular sieve through a pipeline, the molecular sieve is connected to the air compressor through the rotary separation valve, the air compressor is connected to the air filter, and the input end of the air filter is connected to the outside air;

[0008] The rotary separation valve is connected to an exhaust gas tank, and the exhaust gas tank is communicated with the air filter.

[0009] The molecular sieve includes an adsorber A and an adsorber B. Both the adsorber A and the adsorber B are connected to a tee through a pipeline, and the tee is connected to the air filter.

[0010] The rotary separation valve is connected to an air intake pipe, the input end of the air intake pipe is connected to the output end of the air compressor, and the output end of the air intake pipe is connected to the input end of the rotary separation valve;

[0011] The rotary separation valve includes a first pipeline and a second pipeline, the output end of the first pipeline is connected to the adsorber A, and the output end of the second pipeline is connected to the adsorber B;

[0012] The tube body of the first pipeline is provided with a first valve, and the tube body of the second pipeline is provided with a second valve.

[0013] The first pipeline is connected to a first nitrogen row pipe, on which a third valve is provided. The second pipeline is connected to a second nitrogen row pipe, on which a fourth valve is provided.

[0014] The output ends of the first nitrogen exhaust pipe and the second nitrogen exhaust pipe are both connected to the exhaust gas tank;

[0015] The waste gas tank is provided with a pressure relief valve.

[0016] The exhaust gas tank is provided with a return pipe, the input end of the return pipe is connected to the exhaust gas tank, and the output end is connected to the air filter;

[0017] The return pipe is provided with a one-way valve.

[0018] The air filter includes a filter layer and a back-blowing channel. The back-blowing channel is located downstream of the filter layer and is connected to the return pipe.

[0020] A fine sieve tower is provided between the molecular sieve and the flow sensor, and one or more adsorption materials selected from the group consisting of activated carbon, silica gel, activated alumina, manganese oxide, zeolite, and polyamide resin are provided in the fine sieve tower.

[0021] The beneficial effects of the present invention are as follows: the rotary separation valve of the present invention has significant technical advantages. Through the control of the rotary separation valve, the two adsorbers of the molecular sieve can realize alternating operation, so that one adsorber is adsorbing oxygen while the other adsorber is in a regeneration state. Specifically, after one adsorber completes adsorption, the separated oxygen is partially transported to the atomizer through the rotary separation valve, and the remaining oxygen is used to back-blow the other adsorber, and the nitrogen therein is back-blown to the waste gas tank. This alternating operation method not only ensures the continuity of the oxygen supply, but also realizes the efficient regeneration of the molecular sieve, avoiding the disadvantage of the traditional system that requires shutdown for regeneration, and greatly improving the operating efficiency and reliability of the system;

[0022] This utility model uses nitrogen from the exhaust tank to backflush the air filter, effectively solving the problem of dust accumulation and reduced filtration efficiency after prolonged use. This backflush cleaning method not only allows the air filter to be cleaned without disassembling, but also utilizes the nitrogen resources already in the system, avoiding additional energy consumption and maintenance costs. This automatic cleaning mechanism maintains the air filter's filtration effect over time, significantly extending its service life and improving the overall system's operating efficiency and stability.

[0023] Through the rotary separation valve and air filter backflushing cleaning technology of the utility model, the efficiency of the entire atomizer system has been significantly improved. First, the application of the rotary separation valve enables the molecular sieve to be regenerated without affecting the oxygen supply, ensuring a continuous supply of high-purity oxygen. Secondly, the backflushing cleaning mechanism of the air filter effectively maintains the clean state of the filter, avoiding the decrease in system efficiency due to filter clogging. The combination of the two technologies enables the system to maintain stable gas source quality and efficient working state during operation, reduces maintenance frequency and cost, and improves the overall reliability of the system;

[0024] This utility model fully utilizes the nitrogen resources within the system. By using the nitrogen in the waste gas tank for backwash cleaning of the air filter, it achieves resource recycling and has excellent environmental benefits. Furthermore, by avoiding frequent maintenance downtime and additional energy consumption, the system also excels in energy conservation. By optimizing the system's workflow and resource utilization, this invention achieves the goals of high efficiency, energy conservation, and environmental protection.

[0030] The molecular sieve 4 includes an adsorber A401 and an adsorber B402 . Both the adsorber A401 and the adsorber B402 are connected to a tee 9 through a pipeline, and the tee 9 is connected to the air filter 2 .

[0031] The rotary separation valve 5 is connected to the intake pipe 10, the input end of the intake pipe 10 is connected to the output end of the air compressor 3, and the output end of the intake pipe 10 is connected to the input end of the rotary separation valve 5. The rotary separation valve 5 includes a first pipeline 501 and a second pipeline 502. The output end of the first pipeline 501 is connected to the adsorber A401, and the output end of the second pipeline 502 is connected to the adsorber B402. The tube body of the first pipeline 501 is provided with a first valve 503, and the tube body of the second pipeline 502 is provided with a second valve 504.

[0032] The first pipeline 501 is connected to a first nitrogen pipe 505 , on which a third valve 507 is provided. The second pipeline 502 is connected to a second nitrogen pipe 506 , on which a fourth valve 508 is provided.

[0033] The rotary separation valve 5 is connected to the exhaust gas tank 8, the exhaust gas tank 8 is connected to the air filter 2, the output ends of the first nitrogen row pipe 505 and the second nitrogen row pipe 506 are both connected to the exhaust gas tank 8, the exhaust gas tank 8 is provided with a pressure relief valve, the exhaust gas tank 8 is provided with a return pipe 801, the input end of the return pipe 801 is connected to the exhaust gas tank 8, the output end is connected to the air filter 2, and the return pipe 801 is provided with a one-way valve.

[0034] The air filter 2 includes a filter layer and a back-flushing channel. The back-flushing channel is located downstream of the filter layer and is connected to the return pipe 801 .

[0035] A flow sensor 7 is provided between the molecular sieve 4 and the atomizer 1 .

[0036] A fine sieve tower 11 is provided between the molecular sieve 4 and the flow sensor 7 . One or more adsorption materials selected from the group consisting of activated carbon, silica gel, activated alumina, manganese oxide, zeolite, and polyamide resin are provided in the fine sieve tower 11 .

[0037] During actual use of the present invention: air enters the air compressor 3 through the air filter 2, and the compressed air enters the adsorber A401 and adsorber B402 through the rotary separation valve 4 for adsorption separation. The controller 6 controls the rotary separation valve 5 to change the adsorption cycle and distribute the flow direction of intake and exhaust. Taking one cycle in the process as an example, the compressed air enters the adsorber A401. At this time, the first valve 503 and the fourth valve 508 are open, and the second valve 504 and the third valve 507 are closed. The nitrogen in the air is adsorbed into the adsorber A401 of the molecular sieve 4, and the oxygen flows out through the tee 9 at the top of the adsorber A401. A part of it is used to backflush the adsorber B402 in the desorption state, and the other part is output through the fine sieve tower 11 and the flow meter. Before the molecular sieve in adsorber A401 reaches critical adsorption saturation state 0, controller 6 closes valves 1003 and 1008, and opens valves 2004 and 3007.

At this time, all valves are closed, and only the valves of the waste gas tank 8 and the air filter 2 are opened. After the nitrogen sent out from the first nitrogen pipe 505 and the second nitrogen pipe 506 is stored in the waste gas tank 8, the one-way valve is opened by the control system to allow the nitrogen to enter the backflush channel of the air filter 2 through the reflux pipe 801. The output end of the backflush channel is connected to the downstream of the filter layer, and backflush is carried out from the downstream to the upstream of the filter layer to achieve the impurities in the filter layer being blown back to the outside air.
