Description
Technical field
The present invention relates to a kind of system of injecting type vacuum preparation ice slurry.
Background technology
Ice slurry refers to contain the solid-liquid two-phase aaerosol solution of tiny ice crystal particle, and the diameter of these ice crystalses is tens to the 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.The vacuum ratio juris is to spray liquid water droplets in vacuum tank, the flash distillation of part drop, and heat absorption, make a part of droplet solidification become ice crystal simultaneously, mixes with the aqueous water that is left to form the ice slurry.As long as keep vacuum in container, the process that forms the ice slurry can continue to carry out.This shows, keep vacuum particularly important for the vacuum method preparing ice slurry.Generally take at present the vavuum pump extracting vacuum, vavuum pump has running gear, wearing and tearing can occur, and vacuum can descend, and this pump noise is also large, oil consumption, power consumption.Vavuum pump generally can not aspirate condensable gas, and emulsification can occur.Although water ring pump is pump up water steam directly, its vacuum is lower, also relatively maximizes.Therefore be badly in need of proposing the system that a kind of novel energy-conservation vacuum producing ice is starched.
Summary of the invention
The purpose of patent of the present invention is to propose a kind of system of injecting type vacuum preparation ice slurry, utilizes now to solve that vavuum pump forms that vacuum comes that the vacuum of preparing ice slurry is difficult to guarantee, complex structure, problem that energy consumption is high.
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; The 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; The vacuum tank bottom is provided with ice slurry outlet.
As improvement, the described concentric circles that diameter increases successively that is shaped as of catching water coil.
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, and easy and simple to handle without running gear, 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, keeps better vacuum.
