Abstract

The invention discloses a heat exchange mechanism used for a sea water desalination system. The heat exchange mechanism used for the sea water desalination system comprises a pressure reducing mechanism, a heat exchange mechanism and a booster mechanism, wherein the pressure reducing mechanism comprises a pressure reducing pipeline and an expansion valve, the heat exchange mechanism comprises a heat exchange pipeline and a heat exchanger, the booster mechanism comprises a boosting pipeline and a compressor, a heat working medium circulates in the heat exchange pipeline, a water turbine is arranged on the heat exchange pipeline, the water turbine is driven by the heat working medium in the heat exchange pipeline, and the compressor is driven by virtue of a connecting rod shaft. The heat exchange mechanism used for the sea water desalination system has the advantages that a condenser in the traditional desalination technology is abandoned, maximum heat loss, namely condensation heat loss, during sea water desalination is avoided, the adopted heat working medium is industrial circulating water, the recycling rate of heat energy is improved, and functions of the heat working medium are reasonably utilized, so that the heat working medium is taken as a power source of the compressor.

Description

technical field [0001] The invention belongs to seawater desalination technology, and in particular relates to a heat exchange mechanism for a steam-pressed capillary-driven seawater desalination system by utilizing thermal energy and kinetic energy of waste heat working medium in an enterprise with high efficiency. Background technique [0002] The method of turning seawater into freshwater is called seawater desalination, and its essence is to separate the salt and water in seawater. The minimum work of brine separation is the lower line of energy consumption for 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. In order to make the desalination process more economical, try to keep the energy consumption as close as poss...
