Abstract

The invention discloses a pressurized steam type capillary drive sea water desalination system. The pressurized steam type capillary drive sea water desalination system comprises an evaporation condensation module, a pressure reducing module, a heat exchange module and a boosting module, wherein the evaporation condensation module comprises a sea water desalination evaporator, the sea water desalination evaporator comprises a sea water cavity, a porous medium, a desalination steam channel, a heat conducting plate and a condensation cavity, the pressure reducing module comprises a pressure reducing pipeline and an expansion valve, the heat exchange module comprises a heat exchange pipeline and a heat exchanger, and the boosting module comprises a boosting pipeline and a compressor. The pressurized steam type capillary drive sea water desalination system is characterized in that a condenser in the traditional desalination technology is abandoned, and maximum heat loss, namely condensation heat loss, during sea water desalination is avoided; besides, sea water supplement is driven by utilizing a capillary force, pump power is not needed, and especially the adopted porous medium is a material with low thermal conductivity, so that sensible heat loss due to discharge of strong brine is greatly reduced.

Description

technical field [0001] The invention belongs to the seawater desalination technology, and particularly relates to a system for high-efficiency utilization of the thermal energy and kinetic energy of the waste heat working medium of an enterprise to carry out pressure-vapor capillary-driven seawater desalination. Background technique [0002] The method of turning seawater into freshwater is called desalination, and its essence is to separate the salt and water in the seawater. The minimum work of brine separation is the downline of the energy that must be consumed by seawater desalination. Only when the separation project is completely reversible, the work consumed by separation is the minimum work. Due to the inevitable irreversibility of the actual process, the energy required for the desalination process is several times, even thousands of times, the minimum work. To make the desalination process more economical, try to keep the energy consumption as close to the minimum...
