[0035] Example 2:

[0036]The above-mentioned Embodiment 1 of the present invention is a case where the ice storage tank is divided into three sub-slots in three equal parts. In Embodiment 2, the ice storage tank can be equally divided into two sub-slots or equally divided into two or more other number of sub-slots. In other embodiments, step 1: arbitrarily select the Nth sub-slot and the Mth sub-slot, the N and the M are any positive integers that are not identical, select the Nth sub-slot for ice making, and use the Mth sub-slot to make ice. The hot water in the sub-tank is heated and decrystallized, the lower regulating valve on the lower water intake pipe of the Nth sub-tank is opened, and the on-off valve on the ice slurry pipe is opened, and the lower regulating valve of the Nth sub-tank is kept open. The state of adjusting the opening degree, maintaining the state that the upper regulating valve of the Mth sub-slot can adjust the opening degree, and closing all other v...

Abstract

The invention relates to a supercooled water type dynamic ice slurry making system. The supercooled water type dynamic ice slurry making system is a technologic system for making a clear water ice slurry by adopting a supercooled water technology. The system is characterized in that one or more separator plates is/are arranged in an ice storage tank, a water level balancing hole is arranged in every separator plate, and the separator plates are equidistantly arranged, and divide the ice storage tank into two or more separate tanks; and an upper water extracting tube and an ice slurry tube are arranged above every separate tank, a lower water extracting tube is arranged below every separate tank, the upper water extracting tubes and the lower water extracting tubes are provided with regulating valves, and every ice slurry tube is provided with a switch valve. In the ice slurry making process, water in one of the separate tank is extracted from the lower portion, high temperature water is extracted from the upper portion of another separate tank, the extracted water and the extracted high temperature water are mixed, the obtained water mixture is sent to a supercooled water heat exchanger through a water pump and forms the ice slurry in a crystallization promoting device, the ice slurry is sent to the upper portion of the one separate tank for making, and above cycle is repeated. The system has the advantages of great reduction of cold heat loss generated by cooling water preheating, great reduction of the preheating loss, and substantial energy saving benefit.

Description

technical field [0001] The invention relates to a supercooled water dynamic ice slurry production technology, in particular to a supercooled water dynamic ice slurry production system capable of reducing preheating losses. Background technique [0002] Supercooled water dynamic ice slurry production technology is a new type of high-efficiency ice-making process. Its basic principle is to use high-efficiency plate heat exchangers to cool liquid water to -2°C. According to the natural supercooling characteristics of water, although the temperature is lower than the freezing point (0°C) when it leaves the heat exchanger, it can still maintain a non-freezing liquid state under certain conditions. The water in this state is Super cold water. After the supercooled water leaves the heat exchanger, it enters the crystal accelerator. The crystal accelerator is a container with ultrasonic radiation, in which the supercooled water will be rapidly transformed into ice slurry under the ...
