Description
Technical field
The present invention relates to a kind of system of injecting type vacuum ice slurry preparation.
Background technology
Ice slurry refers to solid-liquid two-phase aaerosol solution containing tiny ice crystal particle, and the diameter of these ice crystalses is tens to hundreds of micron usually, can be widely used in the fields such as comfort air conditioning system, transport refrigeration, medical treatment and drug-treated, fire-fighting fire extinguishing, energy storage.The preparation method of ice slurry mainly contains fluidized bed process, vacuum method, scrape type method, subcooled water method, direct contact type etc.Vacuum ratio juris sprays liquid water droplets in vacuum tank, and partial drop flash distillation, absorbs heat simultaneously, makes a part of droplet solidification become ice crystal, is mixed to form ice starches with remaining aqueous water.As long as vacuum in maintenance container, the process forming ice slurry can continue to carry out.As can be seen here, vacuum is maintained particularly important for vacuum method preparing ice slurry.Generally take vavuum pump extracting vacuum at present, vavuum pump has running gear, there will be wearing and tearing, and vacuum can decline, and this pump noise is also large, oil consumption, power consumption.Vavuum pump generally can not aspirate condensable gas, emulsification can occur.Although water ring pump can direct pump up water steam, its vacuum is lower, also compares maximization.Therefore the system proposing a kind of novel energy-conservation vacuum producing ice slurry is badly in need of.
Summary of the invention
The object of patent of the present invention is the system proposing a kind of injecting type vacuum ice slurry preparation, is difficult to guarantee, complex structure, problem that energy consumption is high to solve utilize now vavuum pump to be formed vacuum that vacuum carrys out preparing ice slurry.
In order to achieve the above object, the system of injecting type vacuum producing ice slurry of the present invention comprises heater, heat exchanger, steam jet ejector, vacuum tank, gas-water cascade injector, condenser, working medium pump, choke valve, control valve, catches water coil, nozzle, and heater is connected with heat exchanger by pipeline; Gas-water cascade injector is connected with vacuum tank with heat exchanger respectively by pipeline; The import of steam jet ejector is connected with heat exchanger by pipeline, and the outlet of steam jet ejector is connected with condenser by pipeline, the suction inlet of steam jet ejector by pipeline with catch water coil and be connected; Condenser is connected with control valve with throttling arrangement respectively by pipeline; Throttling arrangement by pipeline with catch water coil and be connected; Control valve is connected with working medium pump by pipeline; Working medium pump is connected with heat exchanger by pipeline; Vacuum tank top is provided with nozzle, and nozzle is positioned at catches below water coil; Vacuum tank bottom is provided with ice slurry outlet.
As improvement, described in catch water coil shape be the concentric circles that diameter increases successively.
As further improvement, described heater is solar heat collector.
The advantage of patent of the present invention is: (1) adopts gas-water cascade sprayer pumps water vapour and incoagulable gas to keep the vacuum of vacuum tank, and produces cold with steam jet ejector, without running gear, easy and simple to handle, reliability is high, long service life, and power consumption is few.(2) vacuum keeping apparatus adopts and catches water coil and the associating of gas-water cascade injector, maintains vacuum better.
