Low-energy-consumption lunar in-situ rare gas extraction system and extraction method

Abstract

The invention discloses a low-energy-consumption lunar in-situ rare gas extraction system and method, and belongs to the technical field of lunar soil treatment. The system comprises a screening device, a grinding device and a heating device, and the method comprises the steps that a, screening, specifically, collecting lunar soil through a mechanical arm and putting into the screening device, andscreening the lunar soil with the particle size smaller than 100 micrometers; b, grinding: adding the screened lunar soil into a grinding device for grinding; c, adding the ground lunar soil into a heating device and heating to 150-250 DEG C, and releasing adsorbed rare gas. According to the method, screening and grinding are combined with a traditional heating method to achieve low-power-consumption rare gas extraction on the surface of the moon, the extraction power consumption is only 10-30% of the 900 DEG C hot melting extraction power consumption in the prior art, and moon resource utilization is promoted.

Description

technical field [0001] The invention relates to the technical field of lunar soil treatment, in particular to a low-energy-consumption lunar in-situ rare gas extraction system and an extraction method. Background technique [0002] The lunar soil contains various rich scientific information of the solar system, and is a valuable sample for exploring the historical evolution of the solar system and even the universe; the lunar soil contains many rich mineral resources such as silver, cadmium, lead, tin, titanium, iron, etc. A rare treasure house for long-term research, development and utilization in the future; the lunar soil is located in the surface layer of the moon that is easy to mine, and is the first choice for the construction of lunar bases, mining, road construction and resource extraction in the future. [0003] Rare gases such as He, Xe, etc. on the lunar surface are important energy sources for future deep space exploration, and an efficient and low-energy-consum...

AI Technical Summary

Problems solved by technology

At present, the extraction method of rare gases in minerals on the ground is mainly based on heating and melting. The extraction method on the surface of the moon is also to directly heat and melt the lunar soil at high temperature to release rare gases. Due to heating and melting, the lunar soil needs to be heated to above 900°C. It consumes a lot of energy, and it is difficult to realize it on a large scale on the surface of the moon, which seriously restricts the utilization of rare gases on the lunar surface and the development of lunar resources.
