Abstract

The invention belongs to the technical field of energy development, and relates to a heating device and method for a deep sea hydrate production pipe column, the heating device comprises a sleeve, at least two power generation modules and a heating module, the sleeve is used for fixing the power generation modules and the heating module with the hydrate production pipe column; the power generation modules and the heating module are arranged on the sleeve in a sleeving mode, the heating module is arranged between the two power generation modules, and the power generation modules are connected with the heating module through power transmission lines and supply power to the heating module. By arranging the heating module, secondary formation of hydrates in the mining process is avoided, by arranging the multiple layers of power generation modules with the blades, undulating wave energy can be effectively captured, and stable electric energy is provided for the device.

Description

technical field [0001] The invention relates to a heating device and method for a deep-sea hydrate production pipe column, which belongs to the technical field of energy development, in particular to the technical field of deep-sea hydrate development. Background technique [0002] With the continuous development of society, the consumption of traditional energy such as coal and oil is increasing day by day. Finding new and efficient clean energy has become a necessary prerequisite for the current social development. Formed under special conditions of high pressure and low temperature, the appearance of non-traditional ice-like solid crystalline gas hydrate is likely to change the existing world energy pattern. Natural gas hydrate has the advantages of wide distribution, shallow burial depth, and little pollution after combustion. According to the data, the resource reserves of natural gas hydrate are twice that of traditional energy reserves, and it will be an important e...

Problems solved by technology

[0003] At present, deep-sea hydrate collection is mainly realized through deep-sea hydrate production strings. The flow state in deep-sea synthetic production strings is complex, and solid-liquid-gas three-phase coexistence, but hydrates are very easy in the mixed state of multi-component natural gas due to the memory effect. Secondary formation of hydrates occurs. Secondly, there are many energies such as wind energy, tidal energy, wave energy, and ocean current energy in the deep sea. As a result, the ups and downs of ocean waves will be affected by various energies and lack regularity.

Deep-sea hydrate production strings usually use the energy of ocean waves to provide their own power supply. However, due to the irregular energy of ocean waves, the power supply is unstable and cannot be used for deep-sea hydrate production strings. However, setting up a battery management system or The energy storage device will significantly increase the weight and cost of the device, which is not conducive to deep water hydrate exploitation
