Gas-liquid direct contact fluidized ice preparation system

Abstract

The invention provides a gas-liquid direct contact fluidized ice preparation system. The gas-liquid direct contact fluidized ice preparation system comprises a circulating refrigeration system and a fluidized ice preparation system body, wherein the circulating refrigeration system comprises a refrigeration compressor, a condenser and evaporators; the refrigeration compressor is connected with thecondenser; an outlet pipeline of the condenser is divided into two outlets, one is connected with the high-temperature evaporator, and the other is connected with the low-temperature evaporator; outlets of the high-temperature evaporator and the low-temperature evaporator are connected with the refrigeration compressor through confluence pipelines; the fluidized ice preparation system comprises an air duct, a fan, a nozzle and an ice storage bucket, one end of the air duct is connected with the top of the ice storage bucket, and the other end of the air duct communicates with an inner space at the upper portion of the ice storage bucket above a liquid level; and an ice water filter is arranged at the bottom of the ice storage bucket, the ice water filter is connected with a circulating pump, and the circulating pump is connected with the nozzle. By means of the gas-liquid direct contact fluidized ice preparation system, low-temperature ice-making cooling gas is obtained by the circulating refrigeration system; and the low-temperature ice-making cooling gas surrounds droplets or water mist, and rapidly cools to a freezing point to produce fine ice crystals, that is, the preparationof fluidized ice is completed.

Description

technical field [0001] The invention belongs to the field of fluid ice preparation, and in particular relates to a gas-liquid direct contact type fluid ice preparation system. Background technique [0002] The direct contact method of liquid ice preparation technology is to use direct contact heat exchange to directly contact the refrigerant / brine and water for heat exchange, so that the water cools down and crystallizes to form ice crystal particles. The direct contact methods include liquid-liquid direct contact and gas-liquid There are two types of direct contact. The liquid-liquid direct contact type uses a refrigerant / blanket refrigerant that is incompatible with water and has a specific gravity greater than water as a low-temperature cooling coal. at the bottom of the container, separated from the liquid ice. At present, the research on the liquid-liquid direct contact fluid ice preparation technology has been relatively mature. However, using liquid as the brine not...
