Combustible ice extraction pipe column

Abstract

The invention relates to the field of combustible ice mining equipment, in particular to a combustible ice extraction pipe column. The combustible ice extraction pipe column comprises a plurality of first limiting holes, a limiting structure, conveying structures, fixed plates and a connecting structure. The first limiting holes for limiting the limiting structure are symmetrically in pairs, linearly and equidistantly arranged in the side walls of the conveying structures which are provided with a cylinder structure and used for conveying combustible ice gas. The limiting structure used for fixing the connecting structure is fixed to the conveying structures. The connecting structure is provided with the four fixed plates which are symmetrical in pairs. The fixed plates corresponding to the limiting structure one by one are detachably connected with the limiting structure. The conveying structures are connected with a circulating pipeline for cooling, the interior of the conveying structures is conveniently cooled in the process of land mining and conveying, the problem that danger is caused, and the conveying quality is affected due to the fact that the internal temperature of theconveying structures is too high is effectively solved, and the conveying quality is improved. The two conveying structures are connected through the connecting structure, so that the conveying structures are more convenient to mount and dismount, and the sealing performance between the conveying structures is improved.

Description

technical field [0001] The invention relates to the field of combustible ice mining equipment, in particular to a combustible ice extraction pipe string. Background technique [0002] With the rapid development of society and the advancement of science and technology, combustible ice is mined and used. Natural gas hydrates, organic compounds, and chemical formula CH4·xH2O are combustible ice, which are distributed in deep sea sediments or permafrost in land areas. The ice-like crystalline substance formed under high pressure and low temperature conditions has very high requirements on the transportation pipeline during the mining of combustible ice, so as to ensure the smooth progress of mining. [0003] However, the traditional combustible ice extraction string does not have the function of cooling the pipeline during use, and it is inconvenient to control the sealing and stability of the pipeline connection during use, and it is not convenient to dredge and repair the pipe...
