NOVELTY - Electricity, water and salt are co-produced using condensing-type steam turbine generator set (1) by generating electricity from the steam turbine generator set; introducing the steam turbine generator set exhaust steam into heat exchanger (2) provided with cooling medium to condense it into water; introducing the heated cooling medium into gas-liquid separator (5) to obtain separated secondary steam which is then condensed into water in surface condenser (10) using circulation cooling seawater, and separated liquid brine which can be utilized in chlor-alkali or sodium carbonate production.    USE - Method for co-production of electricity, water and salt using condensing-type steam turbine generator set (claimed).    ADVANTAGE - The method is simple, has high heat energy utilization rate, and enables co-production of electricity, water and salt with high efficiency.    DETAILED DESCRIPTION - Electricity, water and salt are co-produced using condensing-type steam turbine generator set (1) by:    (A) introducing steam into condensing-type steam turbine generator set to generate electricity; introducing the steam turbine generator set exhaust steam with a gauge pressure of less than -0.04 MPa into heat exchanger (2) to heat exchange with cooling medium, which is introduced from storage tank (9) into heat exchanger through forced circulation pump (8), so as to condense it into water; introducing the condensed water into steam trap condensed water drainage device (3) to carry out gas-liquid separation before introducing it into boiler water treatment system (4) so as to enable recycling;    (B) introducing the heated cooling medium, which has a temperature higher than its boiling point, from heat exchanger into gas-liquid separator (5) to obtain separated secondary steam and separated liquid brine having a salt concentration of 300-310 g/L; introducing a portion of the separated liquid brine as qualified raw material brine into chlor-alkali or sodium carbonate production system (7) through forced circulation pump (6); recycling the remaining portion of the separated liquid brine by mixing it with cooling medium to be introduced into the heat exchanger; and    (C) introducing the separated secondary steam from gas-liquid separator into surface condenser (10); adding fresh seawater into cooling tower (13) and then introducing it into surface condenser through cooling seawater circulation pump (14) to heat exchange it with secondary steam so as to condense the secondary steam into fresh water; sending the condensed fresh water from the surface condenser into water supply pipe network (12); pumping out the non-condensable gas in the surface condenser using vacuum pump (11); returning the circulation cooling seawater from the surface condenser to the cooling tower, mixing it with fresh seawater, and then sending it back to the surface condenser to enable recycling.
