Background technology
At present, aggregate second wind cooling, add flake ice and cold water and mix and stir the main pre-refrigeration technique produced as Outputting Pre-cooling Concrete, very ripe.Although the temperature drop depth of each pre-refrigeration technique has its limit, integrated use, still effectively pre-cold-peace concrete outlet temperature can be reduced to design load.
Because the requirement of every engineering to outlet temperature is had nothing in common with each other, no doubt effect is fine for the integrated use of various main precooling technical measures, but Pre-cooling equipment and infrastructure cost high, and refrigeration system operation energy consumption is high, moreover refrigeration system operations staff degree of specialization requires high, greatly reduces the economy of engineering.
Often there is such a case in engineering: after using a certain or two kinds of precooling measures, the outlet temperature from design only differs from 1 ~ 2 DEG C, must add precooling technical measures again.Such as: taking batching plant feed bin first cooling by wind, add flake ice and cold water is mixed as precooling measure, outlet temperature only comparatively designs value difference 1 ~ 2 DEG C, surface wind must be increased again as a supplement cold, but it is air-cooled to increase ground, must corresponding increase surface wind cold burden storehouse and supporting refrigeration workshop and refrigeration system equipment, cause engineering cost increasing degree very big, especially in remote construction of hydropower plant, because landform is precipitous, build the excavation in large-sized wind cooling feed bin and refrigeration workshop, basement process cost is high, add the transport of large-scale refrigeration plant, the installation of refrigeration system, run, maintenance and dismounting etc., cost comparatively common engineering is higher.In addition, because large-sized concrete chilldown system all adopts ammonia as cold-producing medium, then a major hazard source while increasing a set of refrigeration system, is added.
