Ice storage tank with cooling device for evaporative supercooled water continuous ice making system

Abstract

The invention provides an ice storage tank with a cooling device for an evaporative supercooled water continuous ice making system, which can effectively eliminate the supercooled state of the supercooled water and realize the separation of ice water. In the ice storage tank box, the supercooled water droplets collide with the wire mesh for decooling. Its characteristic is that the two adjacent slopes of the corrugated wire mesh make some of the water droplets falling on it rebound and collide with each other, and some small ice crystals will accumulate at the angle between the slopes during the cooling process, and its effect is similar to adding water to supercooled water. In addition, the end of the uppermost wire mesh is installed on the spring, which will accelerate the nucleation and freezing of supercooled water under the action of impact, vibration and "nucleating agent". Under the action of buoyancy, the ice floats on the upper part of the ice storage tank, and the wire mesh installed obliquely on the lower layer not only has the effect of cooling, but also can separate the ice and water. The invention is mainly applied to an 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.
