Cutter-suction natural gas hydrate collecting system

Abstract

The invention discloses a cutter-suction natural gas hydrate collecting system, which belongs to the technical field of new energy exploitation. The cutter-suction natural gas hydrate collecting system comprises a trolley, which comprises a cutter-suction head, a lever arm, a trolley body and a chassis, wherein the cutter-suction head is connected to bottom of front end of the trolley body with the lever arm; a pipeline is arranged under the lever arm for connecting cutter-suction head and trolley body; the trolley body is mounted on the chassis and is a hollow structure; a separator, hydraulic pump station and an electronic storehouse are provided in the trolley body; band tracks are provided on both sides of the chassis; the cutter-suction natural gas hydrate collecting system solves theproblems of small mining area for natural gas hydrate in current seabed and low efficiency of mining, integrates collection, transport and separation, has more reasonable lever arm structure for balanced stress, and is able to recycle major gasified combustible ice to protect the environment.

Description

technical field [0001] The invention relates to the technical field of new energy exploitation, in particular to a cutter suction type natural gas hydrate collection system. Background technique [0002] Natural gas hydrate (combustible ice) is a clean and efficient new energy with large storage capacity. In the future work, we will combine the actual geological conditions in my country's sea areas and the key scientific issues discovered in the exploration and development, and develop trial production suitable for different types of characteristics. , mining technology and technical equipment, and establish a development technical equipment system suitable for the characteristics of my country's resources. [0003] Since combustible ice generally exists in the seabed or permafrost, the existing natural gas hydrate exploitation is restricted by the complex seabed environment, and it is difficult to adopt conventional drilling methods, which makes it difficult to improve the e...

Problems solved by technology

The Chinese patent with the application number 201510568442.0 provides a subsea gas hydrate cutter suction mining method, which provides the corresponding mining vehicles, pipelines and ships, but does not give a specific structure, especially does not explain how to Avoid letting the gaseous material leak into the environment (this is unavoidable in open suction suction mining, due to agitation and friction, some solid-phase combustible ice will liquefy and gasify, and float to the sea surface and enter the atmosphere)
