摘　　要：介绍了溢流和泡焦两种冷焦工艺的原理和主要特点,并进行了简单比较。改进的溢流冷焦工艺流程与常规溢流冷焦工艺流程相比具有流程简单、投资和操作费用低、占地面积小等优点,但冷焦放水时存在蒸汽弥漫及含硫气体排放等问题。改进泡焦工艺流程对冷焦放水进行单独处理,避免了放水过程中的蒸汽弥漫及含硫气体释放,同时降低了冷焦放水罐的清罐频次。The principle and main characteristics of two coke quench processes, i.e. the overflow process and the soaking process, were introduced and compared. The improved overflow coke quench process is superior to the common overflow process due to its simpler process flow, lower investment and operating cost and less floor area. However, the pervasion of steam and the emission of sour gas still need to be solved. For the improved soaking process, such problems were avoided by separately treating the coke cooling water, and the cleaning frequency of coke cooling water tank was also reduced.
