Description

The rotating fluid-jet spray pressure charging type cooling-water machine
(1) technical field: the utility model rotating fluid-jet spray pressure charging type cooling-water machine is to be the vacuum evaporation spraying supercharging Refrigeration Technique of working medium and refrigerating medium with water.Belong to refrigeration plant (F25B), atomising device (B05B), heat-exchange apparatus classes such as (F28F).
(2) background technology: 7-20 ℃ chilled water is extensively used in departments such as what petrochemical industry, metallurgy, weaving and the air-conditioning system, has vast market.The existing equipment of producing this chilled water has lithium bromide refrigerator, ammonia water absorbing refrigerator, steam-ejector refrigerating machine etc.The coefficient of refrigerating performance of these refrigeration machines between 0.5-3 or lower, need be a pyrolysis power with steam and hot water all generally, its equipment complexity, and price is higher.Also there is the corrosion situation in lithium bromide refrigerator.
Steam-ejector refrigerating machine is a compressor reducer with the steam jet ejector, water is evaporated take away the latent heat of vaporization under high vacuum and freezes.Its advantage be water be working medium be again refrigerating medium, the latent heat of vaporization of water is big, and is pollution-free; Device structure is simple, cost is low, reliable.Shortcoming is that coefficient of refrigerating performance is very little, is generally 0.45, and need be power with steam, and consumption of cooling-water is big.
If can keep steam jet ejector is the advantage of working medium and refrigerating medium with water, but need not give birth to steam, but obtain the needed high vacuum of refrigeration, will reduce the energy consumption of injecting type vacuum-refrigerator, improve coefficient of refrigerating performance with press water.Chinese patent ' vacuum cooling-water machine by water injection-jet propulsion ' (patent No. 200410021799.9) is provided with the rotating jet air ejector, and the cold boiler system that water ejector, cooling tower are formed promptly is to adopt press water to obtain the needed high vacuum of refrigeration; Wherein water ejector is as the forevacuum first order compression of air ejector, and the rotating jet air ejector belongs to second level compression; Be a kind of cooling-water machine of the full mechanical compress that obtains with press water, this cooling-water machine coefficient of refrigerating performance improved reach 4-7.Other full mechanical compress cooling-water machine, as: the coefficient of refrigerating performance of piston refrigerator, screw refrigerator, centrifugal refrierator greatly about the scope of 3-4.
Water is the cold-producing medium of the natural environmental-protective of tellurian a kind of latent heat of vaporization maximum.If can use the aqueous water sweat cooling, and not needing boiler, and make it further realize cutting down the consumption of energy, will be a kind of desirable refrigeration machine undoubtedly.For seeking better coefficient of refrigerating performance, the inspiration of pressurized steam distillation sea water desalination method in the recent period, again inquiring into the water vapor pressure compression process draws: the final state of saturated vapor adiabatic compression process must be superheat state, the power that compression consumes has only sub-fraction to be used for saturated supercharging, about 80% the overwhelming majority is consumed in overheated temperature rise, and the compression ratio big temperature rise power consumption of healing is bigger, reaches at 5 o'clock as compression ratio, compress per ton/hour power consumption reach 71kw.The full mechanical compress cooling-water machine of traditional above-mentioned water vapour of reaching a conclusion thus can not obtain high again coefficient of refrigerating performance, must inquire into the new system of preparation chilled water.
(3) summary of the invention: the rotating fluid-jet spray pressure charging type cooling-water machine that the utility model proposes solves the problem that the raising of the full mechanical compress cooling-water machine coefficient of refrigerating performance of existing water vapour is restricted exactly.Its technical scheme is as follows:
