Novel salinity difference energy storage and power device

Abstract

The invention provides a novel salinity difference energy storage and power device, and belongs to the technical field of salinity difference energy. The problem of energy utilization in areas such as river estuaries, ships, submarines and salt lakes is solved. The system comprises a fresh water area, a medium salt area, a high salt area, a first reciprocating linkage gate device for switching salt solutions with different concentrations between the fresh water area and the medium salt area, and a second reciprocating linkage gate device for switching salt solutions with different concentrations between the medium salt area and the high salt area, the fresh water area comprises a fresh water tank and a fresh water supply system, the medium salt area comprises a medium salt tank and an engine acting device, the high salt area comprises a high salt tank, a high salt water supply system and a high salt flat permeable membrane, and the two reciprocating linkage gate devices are identical in structure and are pneumatic gates. Salt solutions with different concentrations in the three areas are switched through switches of the two reciprocating linkage gate devices to form pressure difference to drive an engine acting device to output power. The invention provides a green energy source, and the whole system is simple in structure, free of chemical fuel combustion and low in power generation cost.

Description

technical field [0001] The invention belongs to the technical field of salt difference energy storage, and in particular relates to a novel salt difference energy storage and power device. Background technique [0002] With the rapid development of the global economy, people's demand for energy is increasing day by day. Traditional fossil energy has problems such as large consumption of non-renewable resources and serious environmental pollution. Water conservancy, wind power and other new energy technologies are affected by natural environment conditions, regional adaptability, Operational stability, storage safety and other factors. [0003] At the mouth of the river in each city, there is a natural pressure difference in this place. How to make full use of this part of the pressure difference and convert it into electricity is a very valuable thing; for this clean energy, a large amount of energy is actually needed. However, the cost of traditional energy storage devices...

Problems solved by technology

[0002] With the rapid development of the global economy, people's demand for energy is increasing. Traditional fossil energy has problems such as large consumption of non-renewable resources and serious environmental pollution. Water conservancy, wind power and other new energy technologies are affected by natural environment conditions, regional adaptability, Restrictions on factors such as operational stability and storage safety

[0003] At the river estuary of each city, there is a natural pressure difference in this place. How to make full use of this part of the pressure difference and convert it into electrical energy is a very valuable thing; for this kind of clean energy, a lot of energy is actually needed. However, the cost of traditional energy storage devices is high, so it is urgent to develop efficient and environmentally friendly power generation methods, improve resource utilization, and strengthen the recycling of renewable energy to solve the increasingly prominent energy economy and sustainable development of the ecological environment. question
