As shown in Figures 1 to 2, the gas extraction device 2 is connected to the inlet filter device 1. Furthermore, 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 of the membrane tubes 21 The outer surface of the tube 21 has a plurality of membrane holes 211. In detail, the first predetermined gas entering the filtered air A1 in each membrane tube 21 passes through each membrane tube 21 through a plurality of the membrane tubes 21 through permeation. The holes 211 are purified to form a predetermined purified gas A2; and the second predetermined gas of the filtered air A1 does not pass through the membrane tube 21 but flows along the membrane tube 21, and becomes the retained gas AR.

For example, as shown in Figure 2, according to the gas purification extraction device 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, oxygen enters the membrane tube 21 and then permeates out of the membrane tube 21 to become the predetermined purified gas A2. Therefore, the gas extraction device 2 purifies and extracts oxygen in the air. On the other hand, the permeability of nitrogen in the air (that is, the second predetermined gas) in the membrane tube 21 is lower than that of oxygen, so it does not immediately permeate out of the membrane tube 21 after entering the membrane tube 21 21 becomes the retained gas AR, so the gas extraction device 2 collects nitrogen at the end of the membrane tube 21 to purify and extract the nitrogen in the air.

As shown in Figures 1 to 2, continuing from the 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, under 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 retained gas AR) can increase the amount of oxygen (or the amount of nitrogen) purified and extracted by the gas extraction device 2 In this way, the predetermined purified gas A2 and the retained gas AR (that is, oxygen and nitrogen) with improved purity are obtained.

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 maintain 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 to adjust The predetermined purified gas A2 and the retained gas AR (that is, oxygen and nitrogen) whose purity is too high are reduced.

Of course, the adjustment control means for the predetermined purified gas A2 (or the reserved gas AR) is not limited to the above.
