Abstract

The invention provides a wastewater treater. The treater comprises an upper head, a shell and a lower head, wherein a gas outlet is arranged on the upper head; a concentrated liquid outlet is arranged on the lower head; the shell comprises a vapor-liquid separationsection, a material distribution section, an evaporation section and a liquid storage section along a liquid-phase material flowing direction; a feeding port is arranged on the shell above the material distribution section; a heating vapor inlet and a condensate outlet are arranged on the shell of the evaporation section, and an auxiliary vapor inlet are arranged on the shell of the liquid storage section. The treater provided by the invention can improve the wastewater evaporation area and the liquid film updating speed, and increases a heat transfer rate and a heat transfer coefficient of the vapor and the wastewater.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy saving, in particular to a liquid-phase evaporator, in particular to equipment for concentrating and treating waste water containing salt and high-molecular organic matter. Background technique [0002] Highly saline wastewater refers to wastewater with a total saline mass fraction TDS ≥ 1%, which generally belongs to refractory wastewater. Common high-salinity wastewater mainly comes from wastewater discharged from seawater and industrial production wastewater. The desalination treatment processes of high-salt wastewater mainly include electrodialysis, reverse osmosis, ion exchange and evaporation. Organic wastewater mainly comes from chemical industry, road deicing, food processing and other fields, and also includes printing and dyeing wastewater, petroleum mining and processing wastewater, papermaking wastewater and pesticide industry wastewater. The total amount ...
