Description of drawings
Fig. 1 becomes ice test principle figure for the refrigerating medium that the present invention contains binary additive.
The specific embodiment
Below in conjunction with embodiment the present invention is elaborated.
The invention provides a kind of binary additive configuration that is applied to have in the secondary refrigerating medium anti-freezing property.The combination solution 3 that this additive is made up of Tween-80 (Tween-80), glycerine and glucose, wherein Tween-80 (Tween-80) is 1:400 ~ 1:1000 with the ratio of water, the ratio of glycerine, glucose and water is 1:4:30 ~ 1:4:60.Produce in the process of ice slurry utilizing a refrigerating medium (35% ethylene glycol solution); Low temperature ethylene glycol solution 4 flows in pipe; Carry out heat exchange through low temperature ethylene glycol solution and combination solution 3, generate ice crystals 2 on the tube wall, the ice slurry soft fluffy of generation; No coacervation has flow behavior and heat transfer characteristic preferably; And the glycerine that in additive, has added a little has reduced the viscosity that generates the ice slurry, very easily scraping on tube wall with imitating.
The present invention through with the process of a refrigerating medium heat exchange in; After adding the combination solution additive of this kind prescription, can on tube wall, generate the ice slurry of soft fluffy, very easily scraping; Both had good flowability; No accumulation phenomena has high ice content again, guarantees the good operation of ice slurry device for making and ice slurry aerial cooler effectively.
Embodiment:
Referring to Fig. 1, in filling the tank of 2000ml, adding earlier is glycerine and the glucose of 1:4:30 ~ 1:4:60 with the ratio of water; And then the ratio of adding and water is the Tween-80 (Tween-80) of 1:400 ~ 1:1000, fully stirs, and in heat exchanger tube 1, flows through 35% ethylene glycol solution 4 of (6 ~-10) ℃; Can on tube wall, generate the ice slurry 2 of soft fluffy; Very easily scraping had both had good flowability, no accumulation phenomena; High ice content is arranged again, guarantee the good operation of ice slurry device for making and ice slurry aerial cooler effectively.
The present invention is used to produce the binary additive of ice slurry; Release the secondary refrigerating medium that contains binary additive with the present invention and produce ice slurry technology; The high ice content that has of its generation is starched with better ice mobile, that soft fluffy does not have accumulation phenomena; And ice is starched after ice slurry aerial cooler carries out heat exchange recycle effectively.
