Plus fresh water total amount, and not by space-time and climatic effect, the stable confession such as coastal Drinking Water for Residents and Industrial Boiler moisturizing can be ensured
Water.
Global Seawater desalination technology is planted more than more than 20, including hyperfiltration, low multiple-effect, multistage flash evaporation, electroosmose process, pressure
Steam distillation, dew point evaporation, water-electricity cogeneration, hotting mask coproduction and utilization nuclear energy, solar energy, wind energy, tidal energy seawater desalination skill
Art etc., and multinomial pretreatment and the aftertreatment technology such as micro-filtration, ultrafiltration, nanofiltration.Wherein, multistage flash vaporization is desalinization work
Technology is most ripe in industry, safety in operation highest, is suitable for large-scale and ultra-large type desalting plant.But multistage flash evaporation seawater desalting work
Skill construction investment is high, and power consumption is big, and the operating flexibility of equipment is small, is not suitable for making the occasion of water change greatly；Heat transfer efficiency
It is low.
Utility model content
To solve the problem of prior art is present, the utility model provides one kind by the use of industrial exhaust heat as thermal source, made
The adjustable sea water desalinating unit of water Flexible change.
Specifically, the technical scheme used for：
A kind of waste heat recovery sea water desalinating unit, including boiler and multistage flash distillation device, multistage flash distillation device include heating
Device and Multi-stage flash steam room,
The steam (vapor) outlet of the boiler and the steam inlet of steam turbine are connected, the exhanst gas outlet and flue gas heat exchange of the boiler
The gas approach connection of device；The low pressure exhaust steam outlet of the steam turbine and the steam inlet of flue gas heat-exchange unit are connected, flue gas heat exchange
The steam (vapor) outlet of device and the medium inlet of heater are connected, and the media outlet of heater and the water inlet of boiler are connected；It is described to add
The outlet pipe of hot device is connected with the flash distillation chamber of first order flash chamber by water ejector, previous flash distillation in two adjacent flash chambers
The saline slot of room is connected with the flash distillation chamber of latter flash chamber also by water ejector.
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.
Use device of the present utility model carry out the general principle of desalinization for：1）It is low with steam turbine using boiler smoke
Pressure exhaust steam is exchanged heat, and the low pressure exhaust steam after heat exchange is used as power steam；2）Power steam is passed through the heating of multistage flash distillation device
Device, is heated to raw material seawater；3）Seawater after heating sprays into atomization seawater by water ejector into first order flash chamber,
1. seawater rapid evaporation under low pressure is atomized, after steam is by the vapor-liquid separating device in flash chamber, contacts cold with condensation tube bank
It is solidifying, obtain the low fresh water of saliferous；2. atomization seawater enters flash chamber in the case where high speed is sprayed, and small liquid pearl is due to colliding with each other and and device
Wall Collision coagulation is mixed into falling in the saline slot of flash chamber under drop with the liquid collected by vapor-liquid separating device；Salt solution
Seawater in groove equally rapid evaporation under low pressure, after steam is by the vapor-liquid separating device in flash chamber, connects with condensation tube bank
Condensation is touched, the low fresh water of saliferous is obtained；4）Seawater in saline slot is under the water ejector effect of next stage flash chamber to next
Atomization seawater is sprayed into level flash chamber；Until passing through afterbody flash chamber, strong brine is discharged.
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, seawater can faster be heated, and improves heat exchange speed
Degree.
Meanwhile, on the basis of original Multi-stage flash steam room, the seawater 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 seawater 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 inland sea 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 seawater 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.
Further, the fresh water of multiple flash chambers collects is discharged by fresh water pump.
Further, power steam is after heat exchanger exchanges heat, the boiler water as low temperature, returns to boiler and uses.
Further, followed by multiple boiler water-steam turbine high-temperature high steam-steam turbine low-pressure exhaust steam-power steam
Water after ring turns into the high industry water of salt content, and the industry water individually carries out desalting processing using a flash distillation plant,
Or be mixed into raw material seawater, carry out multistage flash evaporation desalt processing.
The utility model has the advantages that：The utility model accelerates seawater in multistage by increasing water ejector
The speed of service in flash distillation plant, corresponding increased heat energy is by the heat supplement of boiler smoke, while the increase of power consumption
Can also " equivalent to " pass through heat energy using offset.And set up on the basis of original multistage flash distillation device or change set water injection
Device, can be by adjusting the treating capacity of the whole fresh water device of injection stream velocity modulation, and the mode than regulation temperature and vacuum more saves the energy.
