降低初冷器阻力的改造方案及改造效果

Improvement Methods and Effection of Reducing the Resistance of Primary Cooler

初冷器是焦化企业的关键设备,初冷器是净化荒煤气中焦油和萘的重要设备,初冷器运行的好坏直接关系到后系统电捕和净化的运行质量,尤其是已经正常运行的初冷器。若设计之初能够充分考虑初冷器的重要作用,加大冲洗液的分类,不同类别的冲洗液按照其特性做好循环喷洒,一定能够实现初冷器的作用,达到长周期运行的目标。

The primary cooler is the key equipment of coking enterprise,and it is the important equipment to purify the tar and napHthalene in the raw gas.The operation of the primary cooler is directly related to the operation quality of the after system electric capture and purification,especially the primary cooler that has been in normal operation.In fact,at the beginning of the design,the important role of the primary cooler can be fully considered,and the classification of flushing fluid and flushing of different types can be increased According to its characteristics,the washing liquid can be circularly sprayed,which can realize the function of primary cooler and achieve the goal of long-term stability.
