Abstract

The present invention relates to the field of natural gas hydrate exploitation, more specifically to a clean development device for deep-sea natural gas hydrate, which includes a floating platform, an electrical storage device, a liquid storage tank, a windmill generator, a solar heating device and other components, and the floating platform The fixed column is fixed on the seabed, the floating platform is installed on the fixed column of the floating platform, the power storage device, liquid storage tank, windmill generator, solar heating device, liquid acceleration pump and electric heating device are installed on the floating platform, and one end of the output pipeline is connected to the floating platform. The liquid acceleration pump is connected, the other end of the output pipeline is connected with the annular space, the liquid acceleration pump is connected with the power device of the acceleration pump, the ocean current power generation device is installed in the floating platform, and the wave energy power generation device is installed on the fixed column of the floating platform. It can use natural clean energy to heat the liquid, and provide power to inject the heated liquid into the subsea, so as to successfully produce hydrate and fill the space after hydrate production.

Description

A clean development device and method for deep-sea natural gas hydrate technical field The present invention relates to the field of clean energy natural gas hydrate exploitation, more specifically a kind of deep-sea natural gas hydrate A clean development device and method for objects. Background technique Natural gas hydrate is also called "combustible ice" because its appearance is like ice and it can be burned in case of fire. An ice-like crystalline substance formed by natural gas and water under high pressure and low temperature conditions. Hydrates are widely distributed in nature on continents Permafrost, island slopes, uplifts of active and passive continental margins, polar continental shelves, and oceans and some interiors The deep water environment of land lakes. According to rough statistics, the distribution range of seafloor hydrates is about 40 million square kilometers, accounting for 30% of the total ocean area. 10%, the reserves of seabed combu...

Problems solved by technology

[0003] The offshore mining of hydrates is far away from the mainland, so it is more difficult to replenish the power of the mining equipment at a long distance, and the consumption of the required power is also a huge capital cost

At present, there is no device at home and abroad that utilizes the potential energy of the ocean itself to mine hydrates. The common energy sources in the ocean are ocean current energy and wave energy, or offshore solar energy and wind energy. Therefore, it is reasonable to design a clean development device for deep-sea natural gas hydrates. Efficient production of hydrates is necessary
