Description
Technical field
The invention belongs to boiler feed water chemical processing fields, are related to a kind of water treatment agent, and specifically a kind of high-pressure boiler is used more
Imitate phosphate-free water treatment agent and preparation method thereof.
Background technique
High-pressure boiler is one of most important power-equipment of present industrial production, and operating condition is special, the high requirements on the equipment.
It is easily heavy to dissolve the impurity such as a small amount of colloid, calcium, the iron in water in the environment of high temperature and pressure for boiler water as energy transmission medium
Product forms dirt, is deposited on equipment surface, equipment is caused to be corroded, cause to damage to equipment.Especially in the special work of high temperature and pressure
Make under environment, boiler plant surface stress is very big, and corrosion damage can also bring some potential safety problems, therefore need under regular situation
Agent-feeding treatment is carried out to boiler water, with regulating water quality, delay or reduce high-pressure boiler generation dirt as far as possible.
The high-pressure boiler water treatment agent of mainstream is phosphorus system medicament at present, and this medicament is easy after being added to boiler feed water
It forms calcium phosphate precipitation and boiler is finally discharged.But there are certain drawbacks for this technology: it is more demanding to system loading,
The phenomenon that often failing, while further increasing with environmental requirement, phosphatic discharge is also as production run
Bottleneck problem, so researching and developing more perfect without phosphorus water-treating agent of boiler becomes the task of top priority.
