Description

Technical field

[0001] The invention belongs to the technical field of treatment of water, wastewater, sewage or sludge, and specifically relates to a regenerative multi-stage flash seawater desalination device with multiple recovery and utilization of heat energy. Background technique

[0002] The multi-stage flash seawater desalination system makes the hot brine flow through several flash chambers with gradually decreasing pressure. At this time, the ambient pressure is lower than the saturated vapor pressure corresponding to the temperature of the hot brine, and the hot brine is rapidly partially vaporized. Steam becomes fresh water after condensation. It has the advantages of simple and reliable equipment, easy to large-scale, large operating flexibility, and the use of low-level heat and waste heat, and has a wide range of application prospects. However, in practical applications, all the latent heat released by the flash steam is used to heat the circulating brine in the co...
