The supply gas is distributed uniformly to each hollow fiber.
A gas separation chamber is formed by forming a supply gas guide channel using a baffle plate so that the permeate gas can efficiently permeate through the gas, and a concentrated gas distribution chamber (gas distribution mechanism) is installed above the pressure vessel. Therefore, the permeate gas distribution ratio can be changed continuously with a simple handle operation. Further, the concentration effect can be further improved by mixing the permeated gas in one section of the concentrated gas distribution chamber as a recycled gas with the supplied gas K, adjusting the pressure, flow rate, and concentration, and then supplying the gas to the gas separation chamber again.
