Technical Field

The utility model relates to a sewage discharging equipment technical field, specifically speaking relates to a full-automatic continuous blowdown flash tank.

Background

In the industrial furnace pollution prevention and control, pollutants in the flue gas of the furnace need to be removed through a combined removal technology, a great deal of sewage is discharged in the pollutant removal process, the sewage needs to be treated, the continuous sewage discharged from a boiler is saturated water under the working pressure of the boiler, the temperature is high, the enthalpy is large, if the pressure is suddenly reduced, the vaporization point of the water is reduced, the original saturated state is destroyed, over-heat is released from part of the water to become saturated water under new pressure, and part of the water absorbs latent heat of evaporation to become steam. The evaporation is called flash evaporation, the continuous blowdown expander obtains secondary steam by using the principle of flash evaporation, and after boiler blowdown water with certain parameters is suddenly input into the expander with the volume several times larger than that of the pipeline from the pipeline, the pressure is reduced, the volume is increased, and thus the steam is evaporated by flash evaporation. The current blowdown expander is inconvenient when using effectively separates soda, leads to the steam after the flash distillation to hardly discharge, and the inside silt of the device is too much, causes the jam easily, and inconvenient maintenance and clearance.
