Temperature determination method for lunar helium-3 resource in-situ exploitation heat release

Abstract

The invention provides a lunar helium-3 resource in-situ exploitation heat release temperature determination method, and belongs to the technical field of lunar resource exploitation. The method comprises the following steps: selecting ilmenite as a representative mineral of lunar helium-3 resource occurrence, carrying out numerical solution by utilizing an established physical model of lunar mineral occurrence helium-3 resource, and establishing high-vacuum and low-gravity physical conditions to conform to the actual environment of the moon; analyzing the evolution law of the release amount and the release rate of the helium-3 resource in the ilmenite along with the heating temperature and the heating time, and finally, comprehensively considering the release rate and the release amount of the helium-3 resource in the lunar soil to determine the optimal heating temperature for in-situ mining of the lunar helium-3 resource. According to the method, the energy consumption ratio during in-situ mining of lunar helium-3 resources can be reduced.

Description

technical field [0001] The invention relates to the technical field of lunar resource mining, in particular to a method for determining the temperature of the heat release in the in-situ mining of lunar helium-3 resources. Background technique [0002] Due to the environment characteristics of high vacuum and low gravity on the moon, the solar wind can be directly injected into the lunar soil, so that a large amount of solar wind materials are stored in the lunar soil, including helium-3 materials. Helium-3 is an efficient, clean, and safe controllable nuclear fusion fuel. 10 tons of helium-3 can meet all the energy needs of the country for a year. At the same time, there are no neutrons in the thermonuclear reactor of helium-3. 3 When used as an energy source, it will not produce radiation. In-situ mining and utilization of helium-3 resources on the moon has become the research content of many countries, which can not only reduce the cost of deep space exploration missions...

AI Technical Summary

Problems solved by technology

[0003] Helium-3 resources exist in the minerals of the lunar soil, and the content in different minerals varies greatly. Currently, the extraction and collection of helium-3 resources is mainly through heating. The heating temperature is too low, and the helium-3 resources are present in the lunar minerals. 3 will not be released, and the heating temperature is too high will lead to a significant increase in cost, so it is very important to determine the heat release temperature of the in-situ mining of lunar helium-3 resources
