我所采用苏联циатим-58实沸点装置来进行减压蒸馏切割油品中的重馏分。但该装置在操作中易漏气,影响操作中的真空度。为此,我们对该装置进行了改装。我们将整个装置(见图1)分为三部分。画入虚线中的是第Ⅰ、Ⅱ部分,虚线外的是第Ⅲ部分,第Ⅰ部分是在常温下使用的。油气在受油器中已凝为液体,剩下少量的不凝气体,其腐蚀性并不大,所以这部分不易漏气。用胶管把泵、压力计、缓冲罐和受油器连接好后,用醋酸织维(加丙酮溶成浆糊状)或石蜡 I used the Soviet Union циатим-58 real boiling point device for vacuum distillation cut heavy oil products. However, the device is easy to leak during operation, affecting the degree of vacuum in operation. To this end, we modified the device. We divide the entire installation (see Figure 1) into three parts. Draw the dotted line is the first part, the second part, the dotted line is the third part, the first part is used at room temperature. Oil and gas in the oil has been condensed into a liquid, leaving a small amount of non-condensable gas, the corrosion is not large, so this part is not easy to leak. Hose to the pump, manometer, buffer tank and the receiver connected, with acetic acid weaving (plus acetone soluble paste) or paraffin
