Patent ID: 10472257

Abstract:
The present disclosure relates to a wastewater flue evaporating device. An wastewater evaporation crystallizer is provided, including an evaporating tube inlet, an inlet flange, an inlet chamber, a pneumatic inlet baffle, an evaporating tube body, a pneumatic outlet baffle, an outlet chamber, an outlet flange, and an evaporating tube outlet which are successively coupled, where the evaporating tube inlet is connected to provide a gas pipeline; the gas pipeline is connected on a flue between an external denitration device and an air preheater; the evaporating tube outlet is communicated with an inlet flue of a dust collector; the evaporating tube body is provided with a wastewater nozzle; and the wastewater nozzle is communicated with a pretreated waste pipe. The present disclosure provides an efficient and energy-saving wastewater evaporation crystallizer which increases evaporation efficiency by bringing in a high-temperature gas at a front end of the air preheater.
