Description
Technical field
The invention belongs to the light technical field of waste heat system, it is related to desalination technology on a kind of ship, and in particular to Yi Zhongji
In the Waste Heat Reuse desalination plant of vortex tube effect.
Background technique
Fresh water is the important leverage resource of operation on the sea, however since space is limited, the fresh water reserves of ship receive sternly
It limits again, it is particularly important that sea water desalting equipment is equipped on ship.
Currently, marine sea water desalting method mainly has the way of distillation, embrane method and a crystallisation, technology is more mature, using most
More is the way of distillation and hyperfiltration.Reverse osmosis desalination device energy consumption is lower, and shipload increases very fast in recent years.But due to
Its sea water preprocessing is required it is stringent, for the fishing boat in seriously polluted neritic zone work, the service life of device and
Product water quality is all not satisfactory.In the ship that goes to sea, distillation sea water desalting device is leading products, and type is more.Distillation
The technology of research hot topic has multistage flash distillation and low temperature multiple-effect distillation in method.
Meanwhile there are a large amount of waste heats in steamer diesel engine vent gas, boat diesel engine can generate a large amount of hot cigarette at work
Gas, and a large amount of unused thermal energy have been taken away in the direct external discharge of a large amount of hot fumes, it is normal that this results in boat diesel engine
The incomplete utilization of energy when work.In addition, needing to carry out it with cooling water cold for the safe operation for guaranteeing cylinder of diesel engine
But, jacket-cooling water also can be with the heat of walking system.For boat diesel engine, the energy conversion efficiency of fuel oil is very low,
Only about 50% is transformed into the mechanical work of internal combustion engine, remaining 50% is waste heat.Wherein about 25% waste heat is taken away by exhaust gas, about
20% waste heat is taken away by jacket-cooling water, and the loss of other waste heats accounts for about 5%.Ship cannot efficiently use this part energy
Amount, the efficiency of energy utilization of system are low.
Low-temperature multiple-effect seawater desalination technology refers to about 70 DEG C of highest evaporating temperature of desalination technology of salt water, by one
Serial Falling Film Evaporator of Horizontal Tube is together in series and is divided into several effect groups, is inputted with a certain amount of steam, passes through multiple evaporation
And condensation, to obtain the distilled water for being multiple times than heating quantity of steam.Since its technical operation temperature is low, elastic big, using each
The low-grade heat source of kind form, can efficiently use ship tail gas waste heat.Currently, carrying out sea to using steamer waste heat both at home and abroad
Water system is light to have carried out some researchs.
The application for a patent for invention of Publication No. CN107555514A " a kind of ship fume afterheat desalination plant and its is answered
With method ", including seawater container, inverted funnel shape dress are set, cooling segment, evaporation section, conveyance conduit and second level cooling device.
The device only once utilizes flue gas, and fume afterheat utilization rate is not high, and evaporation chamber structure is simple, mainly by being passed through
The side bend of high-temp waste gas is constituted, so that the easy fouling of pipe bent position and being difficult to clear up, evaporation of seawater low efficiency, product water quality is not
Height is not easy to investment actual use.
A kind of patent of invention " marine turbine fume waste heat twin-stage recycling sea water desalination dress of publication number CN103145207B
Set ", it include steam generator, the first condensing heat exchanger, the second condensing heat exchanger, blowdown heat exchanger, freshwater storage device, delivery pipe
Road and PID controller.The device forces continuous blowdown according to certain seawater ratio that enters, and avoids salt concentration in generator
It increases, so that scale formation is able to slow down and prevent.It is heated up simultaneously using fresh seawater two-stage, improves the effective use of waste heat.
But it is added in the device compared with multi-controller, improves installation cost, while the device volume is larger, be not suitable for ship seawater system
Light use.
The utility model patent " a kind of vortex tube be sprayed desalination plant " of publication number CN206814421U, including air
Compressor, vortex tube refrigerator, humidifier, condenser, strong brine case, fresh-water tank, water pump and sea water tank.The device is by vortex tube
Refrigeration Technique and spray evaporation seawater desalination technology combine, and realize desalination plant miniaturization.But the device divides vortex tube
Hot and cold side air-flow from after is higher to the air quality requirements for being passed through compressor directly with atomization sea water mixing, and air is in pipe
It is highly prone to pollute in road flow process, so that product water quality is lower.
It is obtained by above-mentioned, marine desalination equipment is lower there are capacity usage ratio at present and desalinates the disadvantages of water is small.
Meanwhile steamer diesel engine vent gas exists largely for the waste heat utilized, can provide heat source for sea water desalination.Therefore, it is necessary to set
Count out the efficient sea water desalting equipment and technique of a kind of low energy consumption, it is ensured that production was not only energy saving when desalinizing seawater, but also can hold
Continue self-sufficient efficient operation.

Thermal release pipe front end is equipped with hot gas injection jets.
9. Waste Heat Reuse desalination plant as claimed in claim 8, it is characterised in that: the preheater is pipe shell type heat exchange
The hot end outlet of device, the vortex tube is connected with the tube side import of preheater, tube side outlet row's atmosphere of preheater, the preheating
The tube side outlet of device is connected into seawater pipe, and tube-side inlet is connected with sea water supply pump.
10. a kind of Waste Heat Reuse desalination plant operation method according to any one of claims 8, which is characterized in that including following step
It is rapid:
In the shell side that the high-temperature tail gas being discharged from diesel engine on ship enters evaporator by high-temp waste gas entrance, to evaporation tube
Interior seawater is heated, and after seawater is heated vaporization in evaporation tube, is risen to vaporium along evaporation tube, is passed through steam (vapor) outlet
Into condenser, it is condensed the outlet pipe discharge that desalinizes seawater for passing through condenser as fresh water, fresh water；
Exhaust gas after heating enters the side suction ports of mixer by waste gas outlet, while the air of air compressor compression enters
The high pressure gas import of mixer, the exhaust gas come out after evaporator heating using jet entrainment mixing, passes through mixer after mixing
Gas outlet enter in vortex tube, cold and hot two strands of air-flows are divided by vortex tube, hot end air-flow enters preheater and evaporates to entering
The seawater of device is preheated, and cold end enters condenser, is condensed to the steam for entering condenser, realizes circulation.
