Seafloor hydrothermal vent temperature difference energy power generating device

Abstract

The invention discloses a seafloor hydrothermal vent temperature difference energy power generating device. The seafloor hydrothermal vent temperature difference energy power generating device comprises a flow guide tube and a cavity; a top end cover and a flange end cover are fixed to two ends of the cavity respectively; the flow guide tube, the top end cover, the flange end cover and the cavity form a sealed cavity; a first temperature difference power generating sheet, a separation board and a second temperature difference power generating sheet are arranged in the sealed cavity; the hot ends of the first temperature difference power generating sheet and the second temperature difference power generating sheet are attached to the outer wall of the flow guide tube; the cold ends of the first temperature difference power generating sheet and the second temperature difference power generating sheet are attached to the inner wall of the cavity; the exterior of the cavity is provided with a plurality of ring ribs; and the lower end of the flow guide tube is provided with a flow guide tube flange and a trumpet-shaped flow separation hood. According to the seafloor hydrothermal vent temperature difference energy power generating device of the invention, a thermoelectric Seebeck effect is utilized, and the flow guide tube is adopted to guide hydrothermal fluid, and the temperature difference power generating sheets are adopted to convert heat energy into electric energy, and therefore, power generation can be realized. The seafloor hydrothermal vent temperature difference energy power generating device of the invention is simple and compact in structure; and the temperature difference of the two ends of each temperature difference power generating sheet is large, and therefore, the utilization rate of hydrothermal energy is high.

Description

technical field [0001] The invention relates to a power generation device, in particular to a thermal difference energy power generation device of a seabed hydrothermal outlet, and belongs to the field of utilization and development of seabed hydrothermal resources. Background technique [0002] Modern seafloor hydrothermal activity is a process of energy and material exchange between the lithosphere and the ocean that generally develops on the boundaries of active plates in the ocean and in the volcanic centers inside the plates. Its prominent appearance is the flow of high-temperature hydrothermal fluids from the sea floor. This marine geological phenomenon has caused special seabed landform features and overlying water body anomalies, and due to the existence of high-temperature heat sources, modern seabed hydrothermal active areas usually have large seabed heat flow anomalies. [0003] The earth is continuously transferring heat from the inside to the outside in vario...
