Abstract

The invention belongs to the field of osmotic energy power generation equipment, in particular to a pressure flow converter and a pressure delay osmotic energy power generation system. The invention aims to solve the problems of low power generation power density caused by relatively low impregnated liquid flow and high energy consumption of the existing pressure delay osmotic energy power generation system. The pressure flow converter comprises a small cylinder body, a middle seal cover, a big cylinder body and a piston connecting rod, wherein a small cylinder piston and a big cylinder piston are respectively arranged in each inner cavity of the small cylinder and the big cylinder; and the two ends of the piston connecting rod are connected with a small cylinder piston and a big cylinder piston respectively. The pressure delay osmotic energy power generation system comprises the pressure flow converter. By utilizing the pressure flow converter, the liquid medium flow of a hydraulic generator can be significantly improved, so that the flow efficiency of the power generator is improved, and the power density of the power generator is improved. The pressure delay osmotic energy power generation system can ensure that concentrated solution side can reach desired back pressure under the condition that external pressure is not applied so that the energy consumption is effectively reduced.

Description

technical field

[0001] The invention belongs to the field of osmotic energy generating equipment, in particular to a pressure-flow converter and a pressure-delayed osmotic energy generating system. Background technique

[0002] As the global population grows, industrialization and automation continue to increase, the demand for energy is also increasing rapidly. However, mineral energy is limited, such as oil, natural gas, coal, etc. are decreasing rapidly, and bring about increasingly serious environmental pollution problems. Therefore, exploring and developing new energy sources that are green, environmentally friendly and have large reserves has become a difficult problem that countries around the world are competing to tackle. According to research, the mixing of river water and seawater can generate huge osmotic energy. The energy density of the osmotic energy produced by the mixture of general seawater (~3.5%) and river water is equivalent to the gravitational potenti...
