渣油是公路部门修建和养护黑色路面的主要材料。目前公路部门油渣的加温及其辅助作业所采用的方法一般是比较落后的,不仅工人的劳动强度大,造成环境污染,而且也损耗大量渣油。为了解决上述问题,并节约能源,我们根据渣油的特点和当地气候条件,设计和使用了太阳能渣油地。油渣的黑度系数为0 .93,对太阳辐的射热有良好吸收能力,吸收率达0.89。我们当阳地区(纬度30°38′)在5至9月施工季节的平均月日照时间达190.5小时。这
Residue is the main material used by highway departments to construct and maintain black pavements. At present, the heating methods of oil residue in highway departments and their auxiliary operations are generally lagging behind. Not only is the labor intensity of the workers high, resulting in environmental pollution, but also a large amount of residual oil is consumed. In order to solve the above problems and save energy, we design and use solar residue according to the characteristics of residual oil and local climatic conditions. The blackness coefficient of oil residue is 0.93, and has good absorption ability to the radiant heat of the solar radiation with an absorption rate of 0.89. The average monthly sunshine duration in our Dangyang area (latitude 30 ° 38 ’) during the construction season from May to September amounted to 190.5 hours. This
