Abstract

The present application discloses a waste argon separation system capable of reducing emission of cryogenic waste argon. The waste argon separation system capable of reducing emission of cryogenic waste argon includes a valve bank, at least two adsorption towers, sewage discharge channels having at least the same number as the adsorption towers, a gas inlet component, and at least one argon reflux component. The valve bank includes a gas inlet valve, an analytic control valve, and at least two sewage discharge valves. The top of each of the adsorption towers is provided with an argon-rich gas outlet, and the argon-rich gas outlet at the top of each of the adsorption towers is connected to each other to form a regeneration channel. The argon-rich gas outlet at the top of each of the adsorption towers is further connected to an argon-rich gas outlet channel.
