Device for exploiting combustible ice

Abstract

The invention discloses a device for exploiting combustible ice with the advantages of reducing the freezing point of water and facilitating combustible ice exploitation, and relates to the field of combustible ice exploitation. The device for exploiting combustible ice is characterized by comprising an offshore platform, a seawater desalination device, a heat exchanger, a first pump and a secondconnecting pipe, wherein the offshore platform is arranged on the sea; the seawater desalination device is arranged on the offshore platform; the heat exchanger is arranged on the offshore platform and is connected with the seawater desalination device through a first connecting pipe; the first pump is arranged on the first connecting pipe; the second connecting pipe is arranged at an outlet of the heat exchanger; a micro-interface reinforcing device for filling natural gas into hot water is arranged on the second connecting pipe; a water discharging pipe extending to an seabed exploitation position is arranged at an outlet of the micro-interface reinforcing device; a natural gas output pipeline extending to the seabed exploitation position is arranged on the offshore platform; a second pump is arranged on the natural gas output pipeline; and a gas-liquid separator is connected to an outlet of the natural gas output pipeline.

Description

technical field [0001] The invention relates to the mining field of combustible ice, more specifically, it relates to a device for mining combustible ice. Background technique [0002] Natural gas hydrate, also known as "combustible ice", is a solid substance formed by mixing water and natural gas under high pressure and low temperature conditions. It looks like ice and snow or solid alcohol. It can burn when exposed to fire. High, clean and pollution-free, combustible ice, as the preferred alternative energy source for the "post-petroleum generation", is a strategic resource with commercial development prospects in the 21st century. In my country, as an important new energy mineral deposit in the future, "combustible ice" will be included in the energy planning for the first time. [0003] The Chinese patent with the notification number CN102817596A discloses a marine combustible ice mining device, which includes the following components: drill bit, drilling rig, mixture c...

Problems solved by technology

[0004] However, when the hot water output pipeline is inputting hot water into the seabed, if the hot water output pipeline passes through the permafrost layer, the hot water in the hot water output pipeline is likely to cool down, increase the viscosity, increase the flow resistance, and even solidify and block the hot water. The output pipeline is not conducive to the mining of combustible ice at this time
