在天然水中,总是含有各种不同成份的杂质,这些杂质的微粒以悬浮物、胶体物、溶解物三种状态分散存在于水中。所以天然水不能直接用作锅炉水,必须经水处理合格后进入锅炉。 悬浮物是指悬浮在水中或水面上的细小砂粒、泥土、水藻、油脂等,其大小在万分之一毫米左右,它不但给化学水处理带来困难,而且还会导致锅水起沫,引起汽水共腾,影响锅炉安全运行。悬浮物一般可以通过沉淀和过滤把它除去。
In natural water, always contain a variety of different components of impurities, these impurities in the suspended particles, colloids, dissolved matter in three states dispersed in water. Therefore, natural water can not be directly used as boiler water, water treatment must be qualified into the boiler. Suspended material is suspended in water or water on the surface of small sand, soil, algae, grease, etc., the size of one ten thousandths of a millimeter, it not only brings difficulties to chemical water treatment, but also lead to pot froth, Cause a total of Tengteng affect the safe operation of the boiler. Suspensions can generally be removed by precipitation and filtration.
