Enter corresponding cooling water heat exchanger heat absorption, after heat source water confluxes in thermal source feed pipe 011 after intensification, enter sea water desalinating unit 03
Heat exchange is lowered the temperature.
Under sea water pump 07 effect, raw material seawater enters sea water desalinating unit 03 condensed steam, and the raw material seawater after intensification is divided
Become two branch roads, a road enters sea water desalinating unit 03 through filter 05 and evaporates, and another road is directly discharged.Do not evaporate concentrated seawater through dense
Seawer outlet 033 is discharged, and condenses fresh water and discharges through water outlet 032.Vacuum pump 06 is used for maintaining sea water desalinating unit 03 vacuum
Degree.
First temperature detection controller 01 controls the sea water of sea water desalinating unit sea intake 031 by flow control valve 04
Flow.First temperature detection controller 01 detect enter sea water desalinating unit 03 thermal source coolant-temperature gage relatively low when, by control
Flow control valve 04 reduces the seawater flow of sea water desalinating unit sea intake 031 it is ensured that seawater desalination system efficiently operates.
When the thermal source coolant-temperature gage of entrance sea water desalinating unit 03 is higher, the first temperature detection controller 01 passes through to adjust flow control valve 04
Increase the seawater flow of sea water desalinating unit sea intake 031.
Second temperature detection controller 08 is used for detecting sea water desalinating unit 03 exit thermal source coolant-temperature gage and controls water supply
Pump 010, the switch of sea water pump 07 and vacuum pump 06.Thermal source coolant-temperature gage is in the work temperature that second temperature detects that controller 08 sets
During degree scope, sea water pump 07 and vacuum pump 06 normal work, feed pump 010 cuts out；Thermal source coolant-temperature gage is higher than that second temperature detects
During the maximum operating temperature that controller 08 sets, feed pump 010, sea water pump 07 and vacuum pump 06 all normal works；Thermal source water temperature
When degree detects, less than second temperature, the minimum operating temperature that controller 08 sets, feed pump 010, sea water pump 07 and vacuum pump 06 are all
Quit work.
So it is achieved that when diesel-driven generator operating load is higher, used heat ensures multi-effect distilling desalination system first
In peak load normal work, unnecessary heat passes through the external quantity of heat given up of cooler 09, it is to avoid seawater desalination system over loading,
And diesel-driven generator cooling system normal work；It is in conventional load when diesel-driven generator runs, seawater desalination system is in volume
The 40-120% normal work of constant load；When diesel-driven generator runs and is in underload, by closing seawater desalination system
Sea water pump and vacuum pump, make seawater desalination system be in energy-saving standby state, reduce the impact to system for the frequent start-stop.
