Description

Back flushing device for softened water of boiler

Technical Field

The utility model relates to a back-flush mounting especially relates to a back-flush mounting of boiler demineralized water.

Background

More water scales can appear in the heating process of the boiler, and when the water scales are formed on the evaporation surface of the boiler, the heat of the fire side can not be quickly transferred to the water side, so that the output of the boiler can be reduced. Along with the evaporation of the water vapor, a large amount of impurities in the salt can be carried in the water vapor, so that the salt deposition condition is caused, and the service efficiency of the boiler is influenced. When the boiler is washed, the washing range is fixed due to the fixed position of the water spray holes, so that washing dead angles are formed, and the washing efficiency in the guide boiler is low.
