Description

Technical Field

[0001] The utility model relates to the technical field of boiler sewage discharge technical equipment, in particular to a continuous sewage discharge expansion container. Background Art

[0002] The continuous blowdown expansion tank is also called the continuous blowdown expander. It is connected to the continuous blowdown outlet of the boiler and is used to reduce the pressure and expand the capacity of the continuous blowdown of the boiler. The blowdown is adiabatically expanded in the continuous blowdown expander to separate into secondary steam and waste hot water. The expander is expanded, depressurized, and heat exchanged before being discharged. The secondary steam is led out through a special pipeline, and the waste hot water is automatically discharged through a float level valve or an overflow regulating valve.
