Background technology
The phase-changing energy-storing technology is to be used for building energy saving field to reduce the important technology that building and heating/energy consumption for cooling solves contradiction between power supply and demand.Ice storage technology then is one of important representative of current phase-changing energy-storing technology.Ice-storage system can be divided into static ice-storage system and dynamic ice cold-storage system.Static ice-storage system is easy to realize, uses comparatively generally, but exists certain defective: the obvious layering of cold water and ice sheet, increased the thermal resistance of solid/liquid interfaces, and reduced heat exchange efficiency, energy loss is big; The bulk ice that the ice of processing is normally static, it is slow to release speed of cooling, and is unfavorable for transporting, and lacks flexibility.In order to overcome these problems, the dynamic ice cold-storage technology is arisen at the historic moment.The ice of producing in the dynamic ice cold-storage system is fluid ice (binary ice, ice slurry), is that the form of mixtures with the small ice crystal and the aqueous solution is present in the cold accumulation system.Ice crystal has bigger heat transfer area, can obtain cooling speed and the characteristic of temperature conciliation preferably faster; Improve storage density of cold, reduced the floor space and the initial cost of ice storage system; Fluid state ice has good flowability, can carry through pump, and the flexibility of cold accumulation system has also obtained promoting greatly.
At present, the preparation method of fluid state ice mainly contains: direct contact heat-exchanging method, facing, vacuum method, subcooled water system fluid state ice method.These methods exist respectively that environmental protection characteristic is poor, energy consumption is big, vacuum state is difficult to keep, the supercooled state instability of water is easy to generate that ice is stifled, the control of evaporating temperature requires the very accurately very high shortcoming of difficulty, therefore research and develop the new and effective method of producing fluid state ice and have great importance.
Summary of the invention
The present invention provides a kind of environmental protection and energy saving, simple in structure, easy to implement based on the ultrasonic atomization spray and evaporated the method for producing fluid state ice and the device of refrigeration technique.
For solving the problems of the technologies described above, technical scheme provided by the invention is:
A kind of device that utilizes ultrasonic wave to prepare fluid state ice comprises: ultrasonic atomization spray equipment and fluid state ice ice-making compartment; Said ultrasonic atomization spray equipment comprises supersonic generator, energy converter and ultrasonic nozzle.Supersonic generator, energy converter and ultrasonic nozzle link to each other successively, and ultrasonic nozzle is positioned at fluid state ice ice-making compartment upper end; There is air intake fluid state ice ice-making compartment upper end, and cooler is separated in inside, and the lower end has air outlet slit to link to each other with centrifugal blower; Fluid state ice ice-making compartment lower end links to each other with frozen water separator, ice machine bin successively.
A kind of method of utilizing ultrasonic wave to prepare fluid state ice, adopt following steps:
The chilled water that (1) will be stored in the freezing water tank is extracted out and is sent in the supersonic atomizer, is atomized into uniform vaporific particle and sprays in the fluid state ice ice-making compartment through ultrasonic nozzle;
(2) low water capacity air is admitted to the fluid state ice ice-making compartment through air intake, the atomization refrigeration coolant-temperature gage is reduced condense into little ice crystal;
(3) ice crystal and the chilled water that freezes are through the frozen water separator separates, and ice crystal gets into ice machine bin, and chilled water gets in the freezing water tank through water pump;
(4) the fluid state ice ice-making compartment higher humid air that contains of discharging is sent to solution deep dehumidifying circulation through centrifugal blower and is carried out dehumidification treatments, sends into the fluid state ice ice-making compartment by air intake again.
Chilled water is to utilize the preposition process of evaporative freezing precooling to produce.
Technical scheme of the present invention is that traditional vacuum method and subcooled water legal system fluid state ice technology are combined, and utilizes the ultrasonic atomization spraying technique simultaneously, and is aided with that evaporative freezing precooling process and solution deep dehumidifying circulation realizes.The cold excessively method of producing fluid state ice of ultrasonic atomization spraying and sprinkling evaporation comprises ultrasonic atomization and evaporated cold two processes of fluid state ice of producing.
Its concrete scheme is following: at first utilize the evaporative freezing precooling process to produce chilled water; In fact the evaporative freezing precooling process is exactly the evaporative cooling process under non-normal temperature operating mode; This process is the pre-treatment process of this programme, and the chilled water of generation is stored in the freezing water tank; Then with temperature 0
oThe above chilled water of C is extracted out from freezing water tank and is sent in the supersonic atomizer through water pump, and chilled water is atomized into uniform vaporific particle by supersonic atomizer and sprays in the ice-making compartment through atomizer; On the other hand, the air of low water capacity also is admitted in the evaporation ice-making compartment simultaneously, and the dry-bulb temperature of air and water capacity are controlled in suitable numerical value through solution deep dehumidifying circulation, and this makes the wet-bulb temperature of air remain on 0
oBelow the C, the pressure in the ice-making compartment is maintained under the three phase point pressure (611.73Pa) the constantly vaporization of droplet surface that then in ice-making compartment, produces by ultrasonic atomization; And absorption heat of vaporization; Make the drop temperature to reduce gradually,, condense into little ice crystal up to the temperature that reaches the freezing point; Pressure in the ice-making compartment can remain on below the 611Pa or vacuum state, and droplet will be cooled to supercooled state this moment.Handled with separating cooler by supercooled water droplets; Water droplet becomes ice crystal after removing the subcooled water state; The ice crystal that generates can mix with the part water that does not freeze and separate through the frozen water separator, and ice crystal is used to produce fluid state ice, and regaining unnecessary chilled water into, freezing water tank continues to utilize.And the air of the higher water capacity of coming out from ice-making compartment can feed and dehumidifies the solution deep dehydrating unit, and the air of dehumidifying low water capacity later gets into again and continues on for ice making in the ice-making compartment.
Beneficial effect of the present invention is following.
1, the present invention mainly with water as cycle fluid, reduced pollution to environment; Save a large amount of electric energy with respect to traditional method, realized the sustainable development of using energy source.
