中压水加热沥青新技术

利用水被加压后,其温度即可升高而不汽化的原理,将水增压作为传热介质加热沥青的新工艺是当前的发展方向.文中分析了中压水加热沥青的可行性,并介绍了工艺设计及主要设备,指出中压水加热沥青比蒸气加温可节约能源25%以上,此导热油方案可节省投资和使用运行费用.

New Technique of Heating Asphalt by Using Middle Pressure Water

According to the principle that water can be raised in temperature without vaporization after its being pressured,the new technique by using pressure water as a heat transfer medium to heat asphalt is a development direction re- cently.The paver has analysed the possibility of heating asphalt by using middle pressure water and introduced the process design and main equipment,it painted that the pressure water heating asphalt can save 25% energy used in vapour heating asphalt,and need less investment and expanse in application than heat conduct oil method.
