Embodiments of the present invention will be described below based on FIGS. 1 to 10 . This description is not intended to limit the implementation of the present invention, but is one of the examples of the present invention.

As shown in FIG. 1 to FIG. 2 , a gas purification and extraction device 100 according to the first embodiment of the present invention includes: an inlet filter device 1 , a gas extraction device 2 and a gas purity control device 3 . In this way, the gas purification and extraction equipment 100 of the present invention can extract specific gases (such as oxygen or nitrogen) in the air in a purified manner, and the extracted predetermined gas is filtered and purified to provide to Workplaces or users with specific gas requirements. The proportion of oxygen in the air is about 21%, and the proportion of nitrogen in the air is about 78%. The gas purification and extraction equipment 100 of the present invention separates and extracts the oxygen and nitrogen in the ambient air to achieve "in the workplace The effect of increasing oxygen" and "increasing nitrogen in the workplace".

As shown in FIG. 1 to FIG. 2 , the inlet filter device 1 performs impurity filtration on the air A0 to be treated to form filtered air A1 . Specifically, the inlet filter device 1 is used to filter the air flowing into the gas purification and extraction equipment 100 , for example, to filter out impurities or particles in the air whose size is below 1 micron (Micrometer, μm).

As shown in Figures 1 to 2, the gas extraction device 2 is connected to the inlet filter device 1 . Further, the gas extraction device 2 has a plurality of membrane tubes 21, and the filtered air A1 enters the plurality of membrane tubes 21 of the gas extraction device 2 from the outlet of the inlet filter device 1, wherein each membrane The outer surface of the tube 21 has a plurality of membrane holes 211 . Specifically, the first predetermined gas of the filtered air A1 entering each of the membrane tubes 21 passes through the plurality of membranes of each of the membrane tubes 21 from each of the membrane tubes 21 by permeation The second predetermined gas of the filtered air A1 does not pass through the membrane tube 21 but flows along the membrane tube 21 to become the retained gas AR.

For example, as shown in Figure 2, according to the gas purification and extraction equipment 100 of the first embodiment of the present invention, the membrane tube 21 of the gas extraction device 2 is a polymer film or an inorganic film and the filtered air A1 Purification forms the predetermined purified gas A2. Due to the permeability of the oxygen in the air (that is, the first predetermined gas) in the membrane tube 21, the oxygen permeates out of the membrane tube 21 immediately after entering the membrane tube 21 and becomes the predetermined purified gas A2. Therefore, the gas extraction device 2 purifies and extracts the oxygen in the air. On the other hand, the nitrogen in the air (that is, the second predetermined gas) has a low permeability compared with oxygen in the membrane tube 21, so it does not permeate out of the membrane tube immediately after entering the membrane tube 21 21 to become retained gas AR, so the gas extraction device 2 collects nitrogen at the end of the membrane tube 21, thereby purifying and extracting the nitrogen in the air.

As shown in Figures 1 to 2, as mentioned above, when the purity of the predetermined purified gas A2 (or the retained gas AR) reaches the lower limit of the purity threshold of the predetermined purified gas (or the retained gas AR), the The gas purity control device 3 increases the output flow rate of the predetermined purified gas A2 (or the output flow rate of the retained gas AR) to increase the purity of the predetermined purified gas A2 (or the purity of the retained gas AR). That is to say, on the premise of maintaining the same air supply pressure, increasing the flow rate of the predetermined purified gas A2 (or the flow rate of the reserved gas AR) can increase the amount of oxygen (or the amount of nitrogen) purified and extracted by the gas extraction device 2 , thereby obtaining the predetermined purified gas A2 and the retained gas AR (ie, oxygen and nitrogen) with increased purity.

When the purity of the predetermined purified gas A2 (or the purity of the retained gas AR) reaches the upper limit of the purity threshold of the predetermined purified gas (or the retained gas AR), the gas purity control device 3 reduces the output flow rate of the predetermined purified gas A2 (or the output flow rate of the retained gas AR) to keep the purity of the predetermined purified gas A2 (or the retained gas AR) within a predetermined purity range. In other words, under the same air supply pressure, reducing the flow rate of the predetermined purified gas A2 (or the retained gas AR) can reduce the amount of oxygen (or nitrogen) purified and extracted by the gas extraction device 2, thereby adjusting The predetermined purification gas A2 and the reserved gas AR (that is, oxygen and nitrogen) that are too high in purity are reduced.

Of course, the adjustment and control means for the predetermined purified gas A2 (or the retained gas AR) are not limited to the above. Under the condition of maintaining the same purity of the predetermined purified gas A2 (or the reserved gas AR), the air supply pressure is increased, and the amount of oxygen or nitrogen purified by the gas extraction device 2 increases, so that the gas purification and extraction equipment 100 The amount of oxygen or nitrogen supplied increases.
