Description

Technical Field

[0001] This utility model relates to the field of gas separation technology, specifically to a separation structure for mixed gases. Background Technology

[0002] In many industrial processes involving chemical reactions, it is often necessary to separate gas mixtures, as purer gaseous substances are beneficial for engineering applications. When a gas mixture is placed in a storage tank, under certain pressure and temperature conditions, gas A in the mixture transforms into a liquid state, while gas B remains gaseous. If gas B is released directly at this point, the pressure change within the storage tank will cause the already liquefied gas A to revert to a gaseous state and be released along with gas B, failing to achieve the desired separation and potentially leading to some degree of environmental pollution.

[0003] Chinese patent discloses a gas separation and storage tank and separation device for mixed gases (application number: 201921586428.3), comprising: a first tank body, which is a shell structure containing a sealed cavity, and a first tank opening with a first valve; and a second tank body, which is also a shell structure containing a sealed cavity, and a second tank opening with a second valve. The second tank body and the first tank body are connected via a conduit, and a third valve is provided on the conduit. However, its temperature control is inaccurate, resulting in low production efficiency. Utility Model Content
