Permeation tube power-generating and circulating system

Abstract

A permeation tube power-generating and circulating system comprises a water conduit (1), a permeation tube (2), a water inlet tube (3), a generator (4), a water duct (5), a reverse osmosis desalination device (6) and a draft tube (7) which are connected in sequence, wherein the water inlet of the water conduit (1) and the water outlet of the draft tube (7) are both located in sea water; the water conduit (1) is obliquely and downwards placed, and the tail end of the water conduit (1) is bent and extends into a fresh water tank; the permeation tube (2) is obliquely and downwards placed, and the extending direction of the permeation tube (2) is parallel to the fresh water tank; the water inlet tube (3) is bent and extends to be connected with the generator (4); the water duct (5) is obliquely and upwards placed, and is then connected with a primer pump of the reverse osmosis desalination device (6); the permeation tube (2) is internally provided with a sensor (8) which is used for monitoring the flow rate and water pressure. The permeation tube power-generating and circulating system has the beneficial effects that the system is sustainable, low in energy consumption, high in efficiency, pollution-free, anti-interference and capable of monitoring, high-efficient circulating work can be realized, and the comprehensive utilization rate of sea water and overall economic and social benefits are obviously improved.

Description

technical field [0001] The invention relates to the technical field of marine technology and power generation equipment, in particular to a permeation tube power generation cycle system. Background technique [0002] The sustainable energy released by mixing freshwater and seawater or low-salinity solution with high-salinity solution can be obtained through forward osmosis, in an osmotic system, water molecules permeate from a low-concentration solution to a high-concentration solution through a semi-permeable membrane to pressurize, The pressurized permeate drives the turbine to generate electricity. Forward osmosis can be regarded as the opposite process of reverse osmosis. Reverse osmosis uses external pressure to offset and exceed the osmotic pressure of raw material liquid to desalinate seawater, while forward osmosis uses osmotic pressure to draw fresh water from seawater. Thereby inducing water pressure, because of the similarity to reverse osmosis, the forward osmosi...

Problems solved by technology

[0003] The existing semi-permeable membrane module is an open membrane, and the permeability of such a structure is not high, and the water flow rate of solutions with different concentrations is small, which leads to the small water flow rate of the turbine, which leads to the low efficiency of the generator; and the permeation The water flow in the membrane tube is not easy to control, and once the water flow increases, it is very easy to cause a tube burst accident; in addition, the tail water left over from power generation is generally discharged directly into the water body without any treatment measures, resulting in potential waste of resources and environmental hazards; at the same time Today, when seawater desalination technology is mature, economy is an important factor in determining its wide application
