The invention provides an offshore floating type water-power co-production platform. A power generation system and a seawater desalination system are organically integrated on a bearing floating body to achieve water-power co-production to supply water and power to offshore life. Low-quality steam of a solar power generation system steam turbine is introduced into a first-effect evaporator of a low-temperature multi-effect seawater desalination device to carry out heat exchange with fed seawater, seawater desalination is achieved through a distillation method, and meanwhile the low-quality steam is condensed, and waste heat of the steam turbine is fully utilized. A small-waterplane-area tetrahedral ship with shake stabilizing fins and a cross arm is adopted as the bearing floating body, and the enough space area and stability are provided for the platform. The requirements of remote islands of China for power and fresh water can be met, and the advantages of being low in manufacturing cost, short in building period, environmentally friendly and the like are achieved. In addition, transfer is convenient, and the number of platforms can be increased or decreased according to the requirements of the islands to achieve flexible application of the platforms. Meanwhile the platform has good stability under the conditions of sea wind and waves.
Description
technical field [0001] The invention relates to an offshore platform, in particular to an offshore hydropower cogeneration platform. Background technique [0002] Diesel engine power generation, photovoltaic power generation and submarine cable power transmission are widely used in existing islands. However, these power generation and power transmission methods have shortcomings. Diesel engine power generation pollutes the environment, with high noise and high fuel consumption, which needs to be constantly replenished with fuel; photovoltaic power generation has low power generation efficiency, small power generation, large footprint, and serious pollution in the production process; the laying cost of submarine cable transmission is high, and laying The risk is high, and daily maintenance is difficult. For islands lacking fresh water resources, fresh water mainly comes from rainwater collection, seawater desalination and continental transportation. Drinking water mainly com...
