Problems solved by technology

There have been oxygen-enriched ventilators or oxygen-enriched health care equipment based on membrane separation technology in the published patents, but these patents have some common problems. As portable equipment, the oxygen-enriched membranes used are roll-type, plate-and-frame or hollow fiber Type membrane module, the flow resistance of feed gas and permeate gas is large, and it is difficult to install and fix. It is difficult to meet the requirements of portable equipment in terms of efficiency, lightness, firmness, and durability. Moreover, the equipment has no oxygen concentration display and lacks an intuitive means of judging performance.

Embodiment 1

[0053] Such as figure 1 As shown, the present invention provides a modular portable air oxygen enrichment and purification equipment using finned membrane modules;

[0054] The components of the oxygen-enriched purification equipment are installed and fixed on the inner casing 18, and the outer casing 19 is covered on the inner casing 18, and the above-mentioned components are fastened and connected by slots and screws. Raw material air passes through the openings on the outer casing 19 and the inner casing 18, and is introduced into the body through the air inlet filter 1, and is driven by the fan 2, enters the finned membrane separator 3, and passes through the finned membrane separator. 3. The inlet port flows to the outlet port. The fins of the membrane separator are composed of membrane bags. The pressure outside the membrane bag is the wind pressure generated by the fan. The inlet pipe 4 is connected to the diaphragm vacuum pump 5, and the inside of the membrane bag is ...

Embodiment 2

[0058] (On the basis of Embodiment 1,) the present invention also provides a vehicle-mounted oxygen-enriched purification equipment (for multiple people to use at the same time);

[0059] The working principle and equipment structure are similar to those in Example 1, but different specifications are set according to the number of users, and the specifications of fans, finned membrane separators, and diaphragm vacuum pumps are enlarged by corresponding multiples (2-5) depending on the number of simultaneous users (2-5 people). times), the oxygen-enriched purified gas output interface is equipped with a one-in-multi-out conversion joint accessory, and the output end is connected to multiple breathing masks for multiple people to use at the same time.

Abstract

The invention relates to the technical field of air oxygen enrichment purifying, in particular to a modular portable air oxygen enrichment and purifying device using a fin type membrane module. The modular portable air oxygen enrichment and purifying device comprises a shell, a draught fan, a fin type membrane separator, a diaphragm type vacuum pump, a mask, an inner chargeable battery and a control system. The interior of the shell is divided into multiple separation cavities through partitions, and the draught fan, the fin type membrane separator, the diaphragm type vacuum pump, the inner chargeable battery and the control system are separated. By means of the technical scheme, the problems that according to a portable device in the prior art, a roll type or plate frame type or hollow fiber type membrane module is adopted as an oxygen permeable membrane for use, raw material gas and permeable gas flowing resistance is large, installation and fixing are difficult, the requirements forthe aspects of high efficiency, lightness, solidness, durability and the like of the portable device can be hardly met, the oxygen concentration cannot be displayed on the device, and the device lacks performance visual judgment means are solved.

Description

technical field [0001] The invention relates to the technical field of air oxygen enrichment purification, in particular to a modular portable air oxygen enrichment and purification equipment using finned membrane modules. Background technique [0002] Human life activities are inseparable from the air, more precisely the oxygen in the air. Oxygen is necessary for the normal metabolism of the human body. In an oxygen-deficient environment, such as the plateau air is thin and the partial pressure of oxygen is lower than that in low-altitude areas, people will have various symptoms of hypoxia, such as headache, dizziness, insomnia, nausea, chest tightness, shortness of breath, severe Some may even faint or die. Studies have shown that for every 12 meters above sea level, the atmospheric pressure decreases by 1mmHg (about 133Pa), and the partial pressure of oxygen also decreases in the same proportion. For example, at an altitude of 4000 meters, the atmospheric pressure is onl...
