The utility model discloses a kind of
sodium sulfate wastewater refining device, including pretreatment component, primary
evaporation crystallization component,
waste heat recovery component, secondary
evaporation crystallization component,
solid-liquid separation component,
liquid storage tank and control component, the utility model is guided
slurry to form
cyclone by multiple
evaporation crystallization component's vertical evaporation
tower inner spiral guide vane, cooperate the
closed loop circulation structure of
forced circulation heater, strengthen heat exchange uniformity;
Waste heat recovery component is compressed after
evaporator top secondary steam and is transported by
gas pipeline, realizes heat source utilization to reduce
energy consumption;The three-stage
filtration mechanism of
solid-liquid separation component is classified by stepped screen group and intercepts
crystal, fine separation is carried out to
slurry in combination with horizontal
centrifuge, ensure the efficient separation of
sodium sulfate crystal and liquid;Each component is connected in series by modularization
layout to reduce fluid conveying resistance, the real-time coordination pump valve and sensor operation of the PLC controller of control component, guarantee
system continuous stable operation.
