氢电导率
1.氢电导率,就是将检测水样先通过一个阳离子交换柱,水样中的阳离子被离子交换树脂中的氢交换,通过交换柱的水样留有阴离子和交换下来的氢离子,然后测定电导率。
1. hydrogen conductivity is testing the water through a cation exchange column, the cations in water are ion exchange resin in the hydrogen exchange, through the column of water exchange with anion and exchange down hydrogen ions, and then the electrical conductivity was measured.
2. 氢电导率抑制了氨对水汽品质检测的影响，电厂热力系统中为了防止金属腐蚀,普遍采用给水加氨处理。氨是挥发性物质,除了与碳酸反应消耗一部分外也基本上留在热力系统循环,系统中氨含量大约在１～３mg/ｌ。而在机组正常运行时,在除盐水、凝结水、蒸汽中的其他杂质成份含量也基本上是微克级,这毫克级的氨造成普通电导率检测不能反映其他杂质成份,所以通过阳离子交换柱将铵根去除后,检测电导率就能准确反映水汽中阴离子的含量。
2. hydrogen conductivity suppress the effects of ammonia on the steam quality testing, and plant system in order to prevent metal corrosion, commonly used water plus ammonia. ammonia is a volatile substance, in addition to part of the outer carbonate reaction consumes basically stay in the loop thermodynamic system, the system ammonia content of about 1 ~ 3 mg/ｌ. while in the normal operation of the unit. in in salt water, condensed water and steam in the other impurities content is basically microgram level, the mg ammonia caused by ordinary conductivity detection does not reflect other impurity elements, so by cation exchange column ammonium after removal, conductivity test can accurately reflect the content of anions in water vapor.
3. 氢电导率能准确反映凝汽器泄漏。例如:以海水作为凝汽器冷却水的某机组,凝汽器发生微量的短时的泄漏,其他在线仪表还没有反映,而氢电导已经有明显的变化。
3. hydrogen conductivity can accurately reflect the condenser leak. for example: to seawater as cooling water in a condenser unit, condenser leak small amounts of short-term occurrence, other online meter has not been reflected, while the hydrogen conductivity have been significant changes.
4.电厂要重视氢导电率表的作用，根据氢电导率的大小变化,进行水汽控制,是目前最直接、简便、有效的检测手段。它能及时、准确地反映水汽质量的变化,能灵敏地告诉运行人员水质变化,并通过对导电度数据变化规律的分析,可以寻找水汽质量变化的原因。
4. power should pay attention to the role of hydrogen conductivity meter, according to the hydrogen conductivity change in size, were vapor control, it is the most direct, simple, effective means of detection. it can timely and accurately reflect the quality of the water vapor changes, can sensitively tell operating personnel changes in water quality, and by analyzing the variation of the conductivity of the data, you can find the reasons vapor quality change.
