Grinding-disk crushing experiment facility and method suitable for in-pipe hydrate particles

Abstract

The invention discloses a grinding-disk crushing experiment facility suitable for in-pipe hydrate particles. The grinding-disk crushing experiment facility suitable for in-pipe hydrate particles comprises a material premixing device (1), a crushing pipeline section, a crushing grinding disk unit, a power unit (2), a receiver (3) and a monitoring control system (4). The invention also discloses a grinding-disk crushing method suitable for in-pipe hydrate particles. The facility is compact in structure, can be used for recrushing natural gas hydrate particles in a transmission pipeline and efficiently grinding large-size natural gas hydrate particles, has the advantages of adjustable grinding particle size and uniform grinding particle size, is simple to operate, and solves the problems of primary separation and fluidized pipe transmission in the solid fluidized exploitation idea.

Description

technical field [0001] The invention relates to the technical field of seabed natural gas hydrate exploitation, in particular to a grinding disc crushing experimental device and method suitable for hydrate particles in pipes. Background technique [0002] Gas hydrate, also known as combustible ice, has huge reserves, more than twice the sum of known carbon fossil fuels. It mainly exists in land permafrost and ocean bottom, and the reserves of ocean bottom gas hydrate far exceed that in land permafrost. It is a new type of unconventional energy with great mining potential in the 21st century. my country's marine natural gas hydrate resources have a very broad prospect. According to estimates by researchers from the Ministry of Land and Resources, the total resources of natural gas hydrates in the South China Sea alone have reached 65 billion tons of oil equivalent, which is about half of my country's total onshore and offshore oil and natural gas resources. . [0003] The wa...
