Full fluid type evaporating system and method for preparing supercooled water ice slurry

Abstract

The invention discloses a full fluid type evaporating system and a full fluid type evaporating method for preparing supercooled water ice slurry. The full fluid type evaporating system comprises a cold media fluid storage tank, a circular pump, a supercooled evaporator, a restricting element, a liquid level detecting device, a temperature detecting device, an electric control unit, a general wateroutlet pipe, a general water inlet pipe, a cold media fluid inlet pipe and a cold media outlet pipe; an output end of the cold media fluid storage tank is in sealing connection with an input end of the circular pump through a pipeline, and an output end of the circular pump is in sealing connection with an input end of the restricting element. Through matching of the liquid level detecting device, the temperature detecting device, the electric control unit, the circular pump, and the cold media fluid storage tank lamp, the heat exchange cold media in the supercooled evaporator is always undera stable state, the stable preparation of cold water and continuous running of the subsequent icing process are guaranteed; the heat exchange efficiency and running stability of the supercooled waterdynamic icing system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cold water ice slurry preparation, in particular to a flooded evaporation system and method for preparing supercooled water ice slurry. Background technique [0002] Generally speaking, industrial and commercial ice making methods can be divided into two categories: direct heat exchange ice making and indirect heat exchange ice making. Direct heat exchange ice-making is the direct heat exchange between water and refrigerant. It has high heat transfer efficiency and high heat transfer capacity. However, due to the generation of corrosive gases, it affects the purity of the refrigerant and affects the operation of the refrigeration system. It has been basically eliminated. . [0003] Indirect heat exchange ice-making is the indirect heat exchange between water and refrigerant or refrigerant, which includes static ice-making and dynamic ice-making: [0004] 1. Static ice making: that is, ice is formed outs...

Problems solved by technology

[0011] However, the way of using brine also has many disadvantages: due to the secondary heat exchange, the overall efficiency of the supercooled water ice making system is relatively low, and the operating cost is high; in addition, an additional brine circulation system is required, It also increases the initial investment of ice making equipment
