Combustible ice core sample storage device

Abstract

The invention discloses a combustible ice core sample storage device and relates to the technical field of combustible ice storage. According to the combustible ice core sample storage device, the problems that in the prior art, combustible ice cannot be preserved or is short in preservation time, and the situation that the combustible ice is subjected to temperature control and accordingly various properties of the combustible ice are researched cannot be achieved are solved. The combustible ice core sample storage device comprises a storage tank and a sealing cover. A boss is arranged on thelower portion of the sealing cover; plug pins are arranged on the lower portion of the boss, and plug holes are formed in the upper portion of the storage tank; the sealing cover is of a hollow structure and internally provided with a battery pack and a CCS which are connected; and the storage tank comprises an outer barrel and an inner barrel, and a semiconductor flexible refrigerating belt is arranged between the inner barrel and the outer barrel. The structure is simple, operation is convenient and rapid, combustible ice samples are stored effectively, the various states of the combustibleice samples are preserved, and scientific analyzing of the combustible ice samples is guaranteed.

Description

technical field [0001] The invention relates to the technical field of combustible ice storage, in particular to a combustible ice core sample storage device. Background technique [0002] Natural Gas Hydrate (Natural Gas Hydrate, referred to as Gas Hydrate) is a new mineral resource discovered during scientific investigations in the 20th century. It is distributed in deep sea sediments or permafrost in land areas. A solid substance produced when mixed under certain conditions. It looks like ice and snow or solid alcohol. It can burn when ignited. It is known as "combustible water", "air ice" and "solid gas". It is known as the most commercially developed in the 21st century. Strategic resource for prospects. Natural gas hydrate is a new type of high-efficiency energy. Its composition is similar to that of natural gas that people usually use, but it is purer. When mining, it only needs to increase the temperature and depressurize the solid "natural gas hydrate" to release a...

AI Technical Summary

Problems solved by technology

[0007] (3) At high temperature, combustible ice will gasify, making it impossible to carry out further scientific analysis;

[0009] (5) Under normal pressure, if the combustible gas in the combustible ice escapes, it will be scattered in a local area, forming a flammable and explosive space, causing a safety hazard;

[0010] (6) When taking out the combustible ice sample, first remove the outer layer of wax film, and the escaped combustible gas cannot be collected for analysis;

[0011] (7) Combustible ice samples are precious, and the cost of taking rock cores is high. If it is damaged, it will cause great waste, and it is also the responsibility of the operator.
