Embodiment 1

[0024] Such as figure 1As shown, the ice storage tank 1 is equally divided into three sub-tanks with equal volumes by the partition plate 9 , that is, the first sub-tank 101 , the second sub-tank 102 and the third sub-tank 103 . A first upper water intake pipe 301 and a first ice slurry pipe 401 are arranged above the first sub-tank 101 , and a first lower water intake pipe 201 is arranged below the first sub-tank 101 . A second upper water intake pipe 302 and a second ice slurry pipe 402 are arranged above the second sub-tank 102 , and a second lower water intake pipe 202 is arranged below the second sub-tank 102 . A third upper water intake pipe 303 and a third ice slurry pipe 403 are arranged above the third sub-tank 103 , and a third lower water intake pipe 203 is arranged below the third sub-tank 103 . The first, second and third lower water intake pipes are respectively provided with a first lower regulating valve 501 , a second lower regulating valve 502 and a third lo...

Embodiment 2

[0036]The above-mentioned embodiment 1 of the present invention is the situation that the ice storage tank is divided into three equal parts. In Embodiment 2, the ice storage tank can be equally divided into 2 sub-tanks or other number of sub-tanks equal to 2 or more. In other embodiments, step 1: arbitrarily select the Nth sub-tank and the Mth sub-tank, the N and the M are any different positive integers, select the Nth sub-tank for ice making, and use the Mth sub-tank The hot water in the sub-tank is heated and decrystallized, the lower regulating valve on the lower water intake pipe of the N sub-tank is opened, and the on-off valve on the ice slurry pipe is opened, and the lower regulating valve of the N sub-tank can be kept Adjust the state of the opening, keep the upper regulating valve of the Mth sub-slot in a state where the opening can be adjusted, and close all other valves; make the water flow from the Nth sub-slot through the cold water heat exchanger and the crysta...

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 ...
