基于液化天然气(LNG)冷量的废旧橡胶低温粉碎工艺流程
Cryogenic pulverization process of waste rubber based on cold energy of liquefied natural gas(LNG)
【摘要】 探讨了废旧橡胶低温粉碎中LNG冷量的利用问题。用空气作为中间冷媒,将LNG冷量先传给空气,再由空气去喷吹冷却胶粉。设计了此冷却换热的工艺流程,进行了物料及冷量的衡算,以实现冷量的有效利用。
【Abstract】 The usage of cold energy in LNG was studied during the waste rubber was pulverized in low temperature.With air used as a middle cold medium,the cold energy of LNG was transferred to air and then the cold air was used to blow and cool rubber granules.The cooling and heat-exchange process was designed,and the equity calculation of mass and cold energy was accomplished to get the effective use of cold energy.
