Fast evaporation system and method used for high-salt wastewater

Abstract

The invention discloses a fast evaporation system used for high-salt wastewater. The system includes a feeding pump, an electromagnetic processor, an ultrasonic processor, an ultrasonic atomizer, an ultrasonic short-distance evaporating chamber, a steam-water and material separator, an air dehumidifier, a dry-air conveyer, an ultrasonic spiral deflector and a residue discharging device. The ultrasonic spiral deflector includes a spiral deflector and a first ultrasonic transducer, wherein the spiral deflector is arranged at the middle part of the ultrasonic short-distance evaporating chamber, and the first ultrasonic transducer is arranged at the external wall of the ultrasonic short-distance evaporating chamber and is connected to the spiral deflector, and the electromagnetic processor isarranged above the spiral deflector and includes a vertically-arranged titanium alloy pipe. Correspondingly, the invention further provides a fast evaporation method for high-salt wastewater. The problem that high-salt wastewater is poor in flowability and quite prone to scale is solved, the high-salt wastewater can be continuously efficiently dried till a water content suitable for burning treatment is reached in one time, and the hazard of the high-salt wastewater is totally removed.

Description

technical field [0001] The invention belongs to the field of wastewater evaporation and concentration, and relates to a rapid evaporation system and method for high-salt wastewater. Background technique [0002] With the acceleration of my country's modernization process, the output of saline wastewater has increased year by year, and the sources have become more extensive. Such as printing and dyeing, pesticides, chemical production, oil and natural gas extraction, food processing and other industries. These salty wastewaters often contain high concentrations of organic matter. If they are directly treated by biological methods, the salts will enter the biochemical process, inhibiting microorganisms, affecting the effect of biochemical treatment, and making it difficult to discharge the effluent. However, the currently commonly used treatment methods have the limitations of high energy consumption, easy scaling, low concentration rate, easy fouling of membrane modules and ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a rapid evaporation system for high-salt wastewater to overcome the problems of poor fluidity and easy fouling of "high-salt wastewater" and to achieve continuous and efficient evaporation of the high-salt wastewater. "High-salt wastewater" is dried to a moisture content suitable for combustion treatment at one time, and the heat released during combustion is greater than the heat absorbed, thereby completely eliminating the harm of "high-salt wastewater"; correspondingly, the present invention also provides a method for using Rapid evaporation method for high-salt wastewater
