The condensed water in power plant includes steam turbine condensate and various kinds of drain water. In addition, there is condensate returned from hot users in thermal power plant, which is combined with make-up feed water to form boiler feed water; untreated condensate generally contains a certain amount of impurities, which come from condenser leakage, corrosion of thermal equipment metal and residual impurities in boiler make-up water, etc Most of the suspended matters contained in it are insoluble, such as iron oxide, iron hydroxide and other corrosion products, which can not be removed by ion exchange. If the corrosion products in condensate water are not treated, they will be sent to the boiler and deposited in the high heat load position to form iron scale, which will affect the heat transfer and safe operation of the furnace tube.
It can directly filter high temperature water;
The amount of backwashing water is small;
The equipment is simple in structure, simple in operation and easy in maintenance.
A wide range of application, a variety of filter types can be selected to achieve the desired separation effect;
Reliable operation, compact equipment, easy to realize automatic control, etc.
