Abstract

The invention discloses high-salt wastewater evaporation type zero-emission complete treatment equipment, which comprises a non-condensable gas cooler, a first-stage separator, a second-stage separator, a first-stage steam compressor and a second-stage steam compressor, wherein one side of the non-condensable gas cooler is provided with a pre-heater, the outlet of the non-condensable gas cooler isconnected to the inlet of the pre-heater, the other side of the pre-heater is provided with a first-stage heater, the outlet of the pre-heater is connected to the inlet of the first-stage heater, theother side of the first-stage heater is provided with the first-stage separator, the outlet of the first-stage heater is connected to the inlet of the first-stage separator, and the other side of thefirst-stage separator is provided with a second-stage heater. According to the present invention, by arranging the first-stage separator, the second-stage separator, the first-stage steam compressorand the second-stage steam compressor, the problems of high consumption of fresh steam, high energy consumption and product deterioration in the material concentration evaporation process with characteristics of high boiling point, high heat sensitivity and high concentration ratio can be solved.

Description

technical field [0001] The invention relates to the technical field of evaporation and concentration, in particular to an evaporative zero-emission complete treatment equipment for high-salt wastewater. Background technique [0002] In recent years, due to the urgent need for energy saving and emission reduction, traditional multi-effect evaporation is no longer suitable for this demand. At the same time, MVR evaporation and concentration technology has been widely used in the world. The existing single-effect MVR evaporation and concentration technology is limited by the technical limit of the steam compressor, and the temperature rise of a single compressor can only be within 25°C. However, for materials with high boiling point, heat sensitivity and high concentration ratio requirements, At present, the existing single-effect MVR working mode and simple multi-effect evaporation can no longer meet the needs, and often face problems such as insufficient temperature rise of t...
