This recovery system 100 comprises: a first gas separation device 11 that separates a first gas G1 including a gaseous substance A and a gaseous substance B different from the gaseous substance A to obtain a second gas G2 in which the substance A content is higher than in the first gas G1; a recovery device 20 that changes the state of the substance A included in the second gas G2 and recovers the substance A; and a third gas circulation path 61 that guides a third gas G3 discharged from the recovery device 20 to the upstream side of the first gas separation device 11. For example, the first gas includes carbon dioxide as the substance A and nitrogen as the substance B.

A gaseous substance collection system that can be used on extraterrestrial celestial bodies is envisaged for collecting target gaseous atoms and molecules that float in a shielded environment at a pressure equal to or less than 1 * 10-5 bar. The shielded environment is defined within a cover placed on top of the granular soil, and in one embodiment, the granular soil is a weathered layer. The cover includes a cover body extending from an edge to a top of the cover. The shielding environment is not communicated with the external environment through the cover body. The mining device further comprises a blade, a heat source and a gas collecting face. A blade extends from the edge and is configured to penetrate particulate soil. A heat source disposed in the cover is configured to heat particulate soil. The gas collection face is disposed in the shielded environment and is configured to maintain a temperature below 100 DEG Kelvin.

A gaseous substance collection system that can be used on extraterrestrial celestial bodies is envisaged for collecting target gaseous atoms and molecules (materials) that float in a shielded environment at a pressure equal to or less than 1 bar. A shielded environment is defined within a cover and skirt arrangement placed on top of granular soil, in one embodiment, the granular soil is a weathered layer. The cap and skirt device generally include a skirt extending from the cap that is substantially sealed over the weathered layer surface to create a shielded environment that prevents gaseous material from escaping into the space. The skirt may be lowered or dragged across the weathered layer surface, even made into a conforming surface. The gaseous material may be mined by a blade or digging tool and a heat source that releases the gaseous material from the weathered layer.

The invention relates to the technical field of gas substance trapping, and provides a device and a system for trapping substances in rarefied gas at an ultralow temperature, the device comprises: a trapper, which is provided with a closed first cavity, an inlet of the first cavity is provided with a first valve body, and the first cavity is internally provided with a thermolator; the storage device is provided with a closed second cavity, an inlet of the second cavity is communicated with an outlet of the first cavity, and a second valve body is arranged at the inlet of the second cavity; when the first valve body is opened and the second valve body is closed, the cold head reduces the temperature in the first cavity so as to desublimate gas in the first cavity; and when the first valve body is closed and the second valve body is closed, the cold head increases the temperature in the first cavity, and the gaseous substance is liquefied. According to the device, multiple cyclic capturing can be carried out after one-time capturing is completed, a large number of substances are captured, the capturing effect is better, sequence sampling can be carried out at different heights, and the use mode is more flexible and diverse.
