摘　　要：以输油管道垢块、金属铁片为研究对象,利用化学试剂、化学试剂与超声波相结合的方法分别对其进行除垢、防垢实验。结果表明,选用10%Na2CO3,10%盐酸,0.5%NaF组成的除垢剂,除垢量可达0.013 1 g/m2,和超声协同作用除垢量可达0.075 9 g/m2;选用0.01%NaOH、0.01%Na3PO4组成的防垢剂防垢,经过1 h,结垢量为6.83 g/m2,而与超声配合使用,经过同样的时间,结垢量为0.25 g/m2,防垢率可达96.3%。该研究说明了超声波对输油管道具有较强的除垢、防垢能力。The experiment of removal of dirt and prevention of dirt through the method of chemical solvent and ultrasonic using DRSL and metaliron tables of carry oil pipeline as research object. The results showed that the quantity of removal of dirt was 0.013 1 g/m^2 by the regents consisting of 10% Na2CO3 ,10% HCI and 0.5% NaF. It can gain 0. 075 9 g/m^2 when ultrasonic wave act; With the preventional regents of 0.01% NaOH and 0.01% Na3PO4 ,the quantity of entrusting is 6.83 g/m^2 after 1 h,with the effect of ultrasonic,the quantity entrusting was 0.25 g/m^2 in the same time,prevention of dirt rate 96. 3%. It was showed that ultrasonic had better ability to make the carry oil pipeline removal and prevention of dirt.
