Connected by water ejector.
The medium waste heat of strong brine heat exchanger is heated to raw material salt solution；Salt solution after heating is by water ejector to
Aerosolized saline is sprayed into primary flash room, 1. aerosolized saline rapid evaporation under low pressure, steam passes through the vapour-liquid in flash chamber point
After device, with condensation tube bank condensation by contact, the low fresh water of saliferous is obtained；2. aerosolized saline enters flash distillation in the case where high speed is sprayed
Room, small liquid pearl is due to colliding with each other and with wall Collision coagulation into falling in the saline slot of flash chamber under drop, with passing through vapour-liquid
The liquid mixing that separator collects；Salt solution in saline slot equally rapid evaporation under low pressure, steam passes through in flash chamber
After vapor-liquid separating device, with condensation tube bank condensation by contact, the low fresh water of saliferous is obtained；Salt solution in saline slot is flashed in next stage
Under the water ejector effect of room aerosolized saline is sprayed into downward primary flash room；Until passing through afterbody flash chamber, discharge dense
Salt solution is sent to flash crystallization desalination system.
Further, afterbody flash chamber is connected by the water inlet of fresh water pump and choke valve and boiler, light with desalination
Water is supplemented with water loss boiler.
Further, because boiler water is damaged, causing the salt content of recirculated water increases, and can increase control system, to heating
The water that device outlet pipe returns to boiler is controlled, while increasing the magnitude of recruitment of desalination fresh water, needed for being drawn by calculating
Backwater amount and rate of water make-up.Heater outlet pipe separately has branch road to discharge unnecessary water.Fresh water pump also separately has branch road to deliver to fresh water
User.The fresh water exchanged heat simultaneously by pre-heater converges also by the fresh water of pump and salt solution multi-stage flash system.
Low pressure exhaust steam of the utility model using the high-temperature flue gas of boiler to steam turbine is heated, the cigarette after temperature reduction
Gas is more convenient for carrying out purified treatment.The temperature of exhaust steam is improved simultaneously, strong brine can faster be heated, and improves heat exchange speed
Degree.
Meanwhile, on the basis of original Multi-stage flash steam room, the salt solution that heater is come out and first order flash chamber and phase
Connection between adjacent flash chamber is changed to using water stream injection pump connection, or directly increases by one group on the basis of original structure
Parallel water stream injection pump connection.This improved advantage is that salt solution enters the chamber of flash chamber, specific surface area in the form of water smoke
Increase, evaporation rate is than simple liquid surface evaporation faster.And there are vaporific evaporation and two kinds of shapes of saline slot inner salt water evaporation simultaneously
Formula, the single handling capacity increase of flash chamber.And due to improving thermal source mechanism, thermal source can be calculated according to actual process completely
Flow and brine flow etc..And what is utilized is industrial smoke waste heat and exhaust steam in steam turbine waste heat, the increase without energy resource consumption.
In order to discharge the vapor of evaporation in time, the servicing unit of steam suction can also be increased, and accelerate condenser pipe
The mode of water flow velocity and/or reduction water initial temperature in beam, accelerates steam condensing rate.
The utility model has the advantages that：The utility model, will by the once utilization to high temperature flue-gas from boiler
The power steam that the low pressure exhaust steam of steam turbine is converted into high temperature is heated to strong brine, further by way of improving the temperature difference
Lift the treatment effeciency of flash tank.The method of nucleus is made by salt crystalline portion reuse and the quickening concentration of high salt coolant-temperature gage is improved
Method, Crystallization Separation efficiency is improved, so that the overall treatment effeciency for improving flash crystallization desalination system.In order to flash crystallization
Desalination system provides enough raw material strong brine, sets up or changes on the basis of original multistage flash distillation device and sets water ejector, can
With the treating capacity by adjusting the whole fresh water device of injection stream velocity modulation, the mode than regulation temperature and vacuum more saves the energy.Two are
