Description

Technical Field

[0001] This utility model relates to the field of oxygen control devices, and more particularly to an oxygen control module. Background Technology

[0002] With the continuous advancement of technology, the demand for gas separation technology is increasing. Hollow fiber membrane fibers are fibrous in shape and have a self-supporting function. Hollow fiber membrane fibers are made from polysulfone and dimethylacetamide as raw materials, processed into hollow filaments, and then coated with a highly permeable polymer, exhibiting selective permeation characteristics. Because water vapor, hydrogen, ammonia, carbon dioxide, and oxygen permeate relatively quickly, while methane, nitrogen, argon, and carbon monoxide permeate more slowly, this allows for the separation of fast-permeating and slow-permeating substances.

[0003] However, the installation and replacement of hollow fiber membrane fibers are relatively troublesome when used. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen control module.

[0005] The innovation of this utility model lies in making the hollow fiber membrane filaments modular, which can be flexibly combined and installed according to different application scenarios. It can be easily integrated and used in small food packaging equipment, large medical equipment or electronic production lines.

[0006] To achieve the aforementioned objectives, the technical solution of this utility model is as follows:

[0007] An oxygen control module includes a housing, which contains a membrane zone and an extraction zone. The membrane zone contains hollow fiber membrane filaments, one end of which is open and the other end is closed. The open end of the hollow fiber membrane filaments is inserted into the extraction zone to connect the membrane zone and the extraction zone. The housing has an extraction port in the extraction zone and a gas flow hole in the membrane zone.

[0008] Furthermore, a purging device is also provided at the membrane region. The hollow fiber membrane fibers are purged to remove nitrogen gas enriched on the surface of the hollow fiber membrane fibers, thereby reducing the influence of nitrogen gas on the oxygen permeation rate of the hollow fiber membrane fibers.

[0009] Furthermore, the purging element is a fan and is located at the closed end of the hollow fiber membrane filament.

[0010] Furthermore, the housing is also provided with dust removal holes for dust discharge.

[0011] Furthermore, the membrane area and the extraction area are separated by glue injection.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, the hollow fiber membrane filaments are made into modules, which can be flexibly combined and installed according to different application scenarios. Whether in small food packaging equipment or in large medical equipment or electronic production lines, they can be easily integrated and used.

[0014] 2. The modular design of this utility model makes component maintenance and upgrades more convenient. When a module fails, it can be quickly replaced without affecting the operation of the entire system. Furthermore, with continuous technological advancements, modules can be easily upgraded to improve component performance and functionality. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0018] Example 1: An oxygen control module includes a housing 1, within which a membrane zone 2 and an extraction zone 3 are provided, separated by adhesive filling. Hollow fiber membrane filaments 4 are provided within the membrane zone 2, each filament having an open end 4.1 and a closed end 4.2. The open end 4.1 of the hollow fiber membrane filaments 4 is inserted into the extraction zone 3, connecting the membrane zone 2 and the extraction zone 3. An extraction port 1.1 is provided in the extraction zone 3 of the housing 1, and a gas flow hole 1.2 is provided in the membrane zone 2 of the housing 1. A dust removal hole 1.3 is also provided on the housing 1.

[0019] A purging element 5 is also provided at membrane zone 2. The purging element 5 is a fan and is located at the closed end 4.2 of the hollow fiber membrane filament 4.

[0020] During operation: The pump draws air through the air extraction port 1.1 and, under the action of negative pressure difference, draws air into the housing 1 through the gas flow hole 1.2. Then, the air passes through the gas separation functional layer on the surface of the hollow fiber membrane 4 to separate nitrogen and oxygen. Oxygen first passes through the gas separation functional layer on the surface of the hollow fiber membrane 4 and enters the membrane pores, entering the extraction zone 3 from the opening end 4.1. Then, it is extracted through the air extraction port 1.1. Nitrogen remains on the surface of the membrane filaments and accumulates in the module. It is slowly discharged through the gas flow hole 1.2 and then purged by the tail purge element 5. This purge can quickly remove the nitrogen accumulated on the surface of the hollow fiber membrane filaments 4, ensuring that the oxygen permeation rate through the membrane is unobstructed.

[0021] The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
