Binary additive for preparing mud-shaped ice slurry by indirect mode

Abstract

The invention discloses a binary additive for preparing mud-shaped ice slurry by an indirect mode and relates to an additive for preparing ice slurry. The additive is a composite solution (3) consisting of tween-80, glycerol and glucose, wherein the ratio of tween-80 to water is 1:400 to 1:1000, and the ratio of glycerol, glucose and water is 1:4:30 to 1:4:60. With the adoption of the secondary refrigerant binary additive for preparing the ice slurry provided by the invention, ice crystal particles (with average particle size of 0.1-1mm) can be generated; the secondary refrigerant binary additive for preparing the ice slurry has excellent thermo-physical property and chemical property, and meanwhile has the following safety characteristics of no pollution to environment, no toxicity, no corrosion, no combustibility and the like, and has high thermal conducting property and flowing property, and low pumping power; and with the adoption of the binary additive for preparing the mud-shaped ice slurry, the problem of addition of antifreeze additive for preparing the mud-shaped ice slurry (with average particle size of 0.1-1mm) in the prior art is solved; and the latent heat of the ice slurry can be fully utilized.

Description

technical field [0001] The invention relates to a binary additive for preparing muddy ice slurry, in particular to a binary additive for preparing muddy ice slurry indirectly. Background technique [0002] It is used as the secondary refrigerant (ice slurry, ice crystal particle diameter 0.1mm~1mm) used in the ice slurry production device and ice slurry air cooler. It should have good thermophysical properties and chemical properties, and it should have good thermophysical properties and chemical properties. Heat transfer performance, flow performance and small pumping power must also be considered such as environmental pollution and toxicity, flammability, material compatibility, corrosion resistance, safety and disposal costs. In order to ensure that the secondary refrigerant (ice slurry) has the above physical and chemical properties, and requires that the ice slurry can be easily scraped off the pipe wall after generation, and can be pumped to the ice slurry air cooler ...

AI Technical Summary

Problems solved by technology

One of the methods is to use glycerol solution + Tween-80 as an additive. The ice particles generated by it do not have good fluidity, but the ice slurry is easily scraped off the pipe wall.

The second method is to use glucose solution + Tween-80 as an additive. The ice slurry produced by it is soft and fine, but the ice slurry has a higher viscosity at low temperature. Compared with method one, it is not easy to scrape off the pipe wall.
