Description
Technical field
The utility model belongs to ice will make the field, be specifically related to the anti-ice crystal transmission device of a kind of jetting type.
Background technology
Ice-storage air-conditioning is a kind of user side administrative skill that the network load peak load shifting is had remarkable effect, this technology is utilized the ice making of electric power unlatching more than needed at night refrigeration unit, the form of cold with ice stored, the peak of power consumption period then discharges cold for the air conditioner user demand by the mode of ice-melt by day, thereby avoid or reduce the electric power that uses peak period, realization is to the peak load shifting of network load, alleviate the peak-valley difference contradiction of network load, improve the operational efficiency in power plant, finally realize energy-saving and emission-reduction benefit of overall importance.
The core of ice-storage air-conditioning is exactly an ice-making system, traditional ice storage technology mainly comprises two kinds of ice ball type and coileds, the ice-making process of these two kinds of ice storage technologies all is by the low temperature non freezing solution from the refrigeration main frame cold transmission feedwater to be frozen under static relatively state, therefore is referred to as static ice cold-storage.The transmission of heat need overcome the big thermal resistance of plastics or metal pipe-wall and ice sheet in static ice-making process, thereby it is low to have a heat transfer efficiency, and ice making speed is slow, many shortcomings such as refrigeration host computer energy consumption height.
The subcooled water formula dynamic ice cold-storage technology that grows up at the inherent technology shortcoming of static state ice cold-storage has then fundamentally solved above-mentioned technical disadvantages, the ice-making process of dynamic ice cold-storage is to utilize glassware for drinking water that the principle of certain degree of supercooling is arranged, at first in heat exchanger, produce and be lower than 0 ℃ subcooled water, guarantee that by special technique subcooled water does not take place by freeze (otherwise can stop up heat exchanger) in heat exchanger simultaneously, wait subcooled water to discharge heat exchanger then and enter afterwards ice generator again, remove supercooled state, generate the ice slurry.The ice slurry that generates is pumped and enters Ice Storage Tank, frozen water natural layering under the effect of density contrast then, and ice is stored in the groove, and water then continues circulation to be sent into cool-heat-exchanger and produced subcooled water, and so circulation realizes dynamic ice-making process continuously.Heat exchange in the dynamic ice cold-storage ice-making process is passed through liquid in crossing cold heat exchanger---and liquid forced convertion mode realizes, therefore has the coefficient of heat transfer far above static ice making, thereby overcome traditional static ice cold-storage the intrinsic coefficient of heat transfer low, energy consumption high-technology shortcoming.
The key of guaranteeing the stable operation of dynamic ice cold-storage ice-making process is effectively to prevent the frozen problem in the cold heat exchanger.Subcooled water is a kind of astable physical form, under effects such as various disturbances such as stirring, impact, ultrasonic wave radiation, perhaps exists and all very easily removes coldly under the situations such as nuclearing centre such as hydraulically rough surface, impurity particle, crystal ice granule in moment, generates ice and starches.Because runner is narrow and small in the cool-heat-exchanger excessively, not only can stop up runner in case generate the ice slurry, also can cause the structural damage of heat exchanging device, so the ice crystal propagation blocking-up of crossing between cold heat exchanger outlet and the ice generator inlet is one of key technology because of the volumetric expansion that takes place after freezing.Ice crystal is best nucleator for subcooled water, and in a single day subcooled water runs into ice crystal will generate new ice crystal around ice crystal rapidly, and the process of this generation ice crystal has strong propagation trend.In dynamic ice-making system, the a large amount of ice crystals that exist in the ice slurry generator have the strong trend of upstream (crossing cool-heat-exchanger) and propagating along the subcooled water pipeline, and as not adopting effective blocking-up, ice crystal has been bamboo telegraph in the cold heat exchanger, thereby freeze heat exchanger, cause the ice making cycle interruption.
