Abstract

The invention discloses a sea water desalting plant with a fixed bar mirror combination for linear solar condensation, and a desalting method thereof. According to the device, mixed bar reflection mirrors are applied to condensation and heat collection to generate liquid or steam at middle and high temperatures, a piston in a gas-liquid combined cylinder is used for directly driving and boosting the liquid or the steam which then enters into a reverse osmosis desalination device, exhaust steam is applied to sea water desalination again by a distillation method, and condensate water is circulated to a solar condensation collector to form semi-closed circulation. According to the sea water desalting plant, as the reflector is fixed, and an absorber is tracked, so that a tracking system is simplified, the energy consumption is reduced, and the system utilization efficiency is improved; and furthermore, sea water desalination by reverse osmosis is driven by high pressure obtained from acting with direct expansion, the exhaust steam is recycled, and energy levels are utilized in echelon and coupling manners, so that the efficiency of available energy is improved. The sea water desalting plant can be used for automatically adjusting pressure and steam temperature required by brackish water and sea water with different concentrations, and has great superiorities when being applied to desalination of the brackish water and the sea water in regions with high wind power along the coast and in a desert land.
