Jet binary ice generator

Abstract

The invention discloses a jet binary ice generator. The jet binary ice generator comprises a pump, a liquid storage box, a refrigerating pipe and an ice storage box which are connected in turn through a pipeline to form a loop, wherein the refrigerating pipe and the ice storage box are connected with a refrigerating machine; ice slurry is arranged in the pipeline; the pump is a booster pump; the pressure of the ice slurry positioned between the liquid storage box and the refrigerating pipe is between 0.1 and 4MPa; the temperature of the ice slurry positioned near a jet outlet of the refrigerating pipe is between -5 and 4 DEG C; a throttle valve capable of limiting the pressure of the ice slurry in the liquid storage box and the refrigerating pipe is arranged at the jet outlet of the refrigerating pipe; and a unidirectional input device capable of introducing gas or liquid unidirectionally is arranged on the liquid storage box. The invention has the advantages that: the jet binary ice generator has low noise and generates small and uniform ice crystal particles; a large amount of low-temperature carbon dioxide exists in the ice slurry, so that the ice slurry has an antibacterial effect and has a dormancy effect on fishes; and ice is made in a jet mode, so that a large amount of binary ice slurry can be quickly made, and the like.

Description

technical field [0001] The invention relates to a refrigeration cold storage device, in particular to a jet-type binary ice generator. Background technique [0002] Binary ice is a promising cooling medium. In recent years, the production, research and application of binary ice (or ice slurry, Ice Slurry) has attracted more and more attention from the ice-making industry. Binary ice is usually a mixture of ice crystal particles with a diameter of 50-100 μm and water. It has the advantage of good fluidity and can be transported by a booster pump. There is no ice layer on the solid heat transfer surface during the ice-making process. , to achieve complete flow heat exchange, so the heat transfer coefficient in the ice making process is large, the heat transfer temperature difference is small, and the COP of the system is significantly improved. Due to the small size of binary ice ice crystal particles, it can achieve a high ice surface area. If binary ice is used for ice sto...
