Waste-liquid polyphase separation apparatus and waste-liquid separation method

Abstract

The invention discloses a waste-liquid polyphase separation apparatus and a waste-liquid separation method. The apparatus comprises atomization equipment, an atomization area, a static-pressure capacity expanding area, a sounding device, an ash outlet, an apparatus inlet and an apparatus outlet; the atomization equipment is disposed at the top of the atomization area below the apparatus inlet; the static-pressure capacity expanding area is disposed below the atomization area and is communicated with the atomization area, and possesses the circulation area larger than that of the atomization area; the sounding device is disposed at the atomization area; the ash outlet is disposed at the bottom of the static-pressure capacity expanding area; and the apparatus outlet is disposed at the later side of the static-pressure capacity expanding area. The separation method comprises atomizing a waste liquid through the atomization equipment, then vaporizing through a high-temperature air flow, so as to separating solid-phase particles and water in the waste liquid, realizing solid particle agglomeration through the sounding device, and realizing accelerated sinking of the solid-phase particles through the static-pressure capacity expanding area; and discharging the gas from the apparatus outlet, so as to realize the purpose of polyphase separation. The apparatus extremely well realizes separation of solid, liquid, gas and the like by employing the high-energy sounding device and unique static-pressure capacity expanding technology.

Description

technical field [0001] The invention relates to a waste liquid multiphase separation treatment collection device and method, in particular to a waste liquid multiphase separation device and separation method that can be used in thermal power, iron and steel and other related fields. Background technique [0002] Currently, wastewater treatment technologies are mainly realized through physical, chemical, biological or a combination of several methods. In general, purely using physical methods for wastewater treatment cannot meet the relevant environmental protection requirements, and chemical or biological treatment methods need to be used in combination. However, biological and chemical treatment methods generally have more complicated processes. For example, biological treatment methods require microbial cultivation, The treatment method requires constant addition of chemicals. In recent years, for some specific wastewater treatment such as power plant desulfurization wast...

Problems solved by technology

The device uses a high-energy sounding device and a unique static pressure expansion design to solve the problem that the solid-liquid-gas mixture is separated by high-temperature evaporation, and the particles are condensed into packages under the action of sound waves, and stall after reaching the static pressure expansion area. The effect further accelerates the sinking and discharge, and further enhances the separation effect of solid, liquid, gas, etc.
