我厂日处理甜菜200吨,采用三效蒸发系统,凝结水排系统的主要设备有排水柱,集水罐(简称水包),泵各三台。原设计(图1)存在的问题是: 1、蒸汽、一效汁汽凝结水,经1、2号排水柱,其温度只能降到123℃、115℃,输送过程中不断自蒸发,水泵往往空转,致使排水不通畅;还常出现水锤现象,损坏管道和止逆阀。 I plant processing sugar beet 200 tons, the three-effect evaporation system, condensate drainage system of the main equipment has a drainage column, water collection tank (referred to as the water package), the pump of the three. The original design (Figure 1) problems are: 1, steam, a steam condensate water effect, the No. 1 and 2 drainage column, the temperature can only be reduced to 123 ℃, 115 ℃, the continuous evaporation process from the water pump Often idling, resulting in drainage is not smooth; often appear water hammer phenomenon, damage to the pipeline and check valve.
