Claims

[Claims for Utility Model Registration] Two separation cylinders filled with separation agents such as adsorbents and absorbents are provided, and untreated mixed gas is supplied to one of the separation cylinders under high pressure to produce one or two types of separation agents. A separation step of discharging the separated treated gas from the discharge port by adsorbing or absorbing the above gases into the separation agent, and passing a part of the treated gas discharged from the other separation tube through a constriction. A regeneration process in which the gas adsorbed or absorbed by the separation agent is removed from the separation agent by supplying the gas under reduced pressure and is discharged from the discharge port is alternately performed at regular intervals in the two separation cylinders. In the pressure swing type mixed gas separation device, the throttle has two ports separately connected to each of the separation cylinders, and the pressure is reduced from the port on the high pressure side to the port on the low pressure side. The two-way pressure reducing valve has an orifice installed in each of the ports, and the pressure, temperature, and flow rate of the untreated mixed gas supplied to the separation cylinder are determined based on the pressure, temperature, and flow rate of the untreated mixed gas supplied to the separation tube. a regeneration flow rate calculation means for calculating the minimum flow rate of the processed gas required for regeneration of the separation agent in the separation cylinder; a pressure calculation means for calculating the pressure of each of the ports necessary to obtain the pressure, a control means for controlling the set pressure of each of the ports in accordance with each of the calculated pressure values, and a set value of the opening area of each of the orifices. A pressure swing type mixed gas separation device characterized by comprising: correction means for correcting each separately.
