Ice storage tank with de-cold device of evaporative supercooled water continuous ice-making system

Abstract

The invention provides an ice storage tank with a de-cold device of an evaporative supercooled water continuous ice-making system, which can effectively remove the supercooled state of supercooled water and realize the separation of ice and water. In the ice storage tank, the supercooled water drop impacts a metal mesh for de-cold. The invention is characterized in that two adjacent inclined planes of the wave-shaped metal mesh lead part of water drops which fall on the metal mesh to mutually collide after rebounding; and small ice crystals can be accumulated at the included angle of the inclined planes during the de-cold course, and the action of the small ice crystals is similar to that of the nucleating agent added to the supercooled water; additionally, the tail end of the metal mesh at the top layer is installed on a spring and can speed up nucleating and freezing of the supercooled water under the actions of impacting, vibrating and the 'nucleating agent'. The ice floats at the upper part of the ice storage tank under the action of floatation; except for de-cold, the metal mesh which is aslant installed at the lower layer can separate ice from water. The ice storage tank provided by the invention is mainly applied to the evaporative supercooled water continuous ice-making system.

Description

technical field [0001] The invention relates to an ice storage tank for an evaporative supercooled water continuous ice-making system, in particular to an ice-water separation ice storage tank with a supercooling removal device for the evaporative supercooled water continuous ice-making system. Background technique [0002] Dynamic ice-making with supercooled water is a new refrigeration technology developed in recent years. Compared with traditional static ice-making, it has higher ice-making rate and energy efficiency. During the dynamic ice making process of supercooled water, the ice layer does not grow on the heat exchange surface, so the thermal resistance between the water and the refrigerant does not change with the ice making process, and the whole system operates stably and has high energy efficiency. Moreover, the "slud ice" produced by supercooled water dynamic ice making is a mixture of ice and water. Compared with block ice, the heat transfer coefficient betwee...

These methods are more reliable, but the device is more complicated

[0004] At present, the method of producing supercooled water by evaporative spraying is a new method, that is, water at a certain temperature is atomized and sprayed through nozzles in a low-temperature and dry air environment to achieve evaporative refrigeration to produce supercooled water (about -2°C). The decooling device generally adopts the method of supercooled water hitting the wire mesh for decooling. This kind of decooling device mainly prevents ice crystals from growing up at the impact point, blocking the metal filter screen, affecting the decooling effect, and reducing the ice storage capacity of the ice storage tank.
