A waste liquid multiphase separation device and separation method thereof

Abstract

The invention discloses a waste liquid multiphase separation device and a separation method thereof. The device comprises atomization equipment, an atomization area, a static pressure expansion area, a sounding device, an ash outlet, an inlet of the device and an outlet of the device; wherein the atomization device Set on the top of the atomization area below the entrance of the device, the static pressure expansion area is set under the atomization area and communicates with the atomization area, and the flow area of ​​the static pressure expansion area is larger than the flow area of ​​the atomization area, and the sound generating device is installed area, the ash outlet is set at the bottom of the static pressure expansion area, and the device outlet is set at the side of the static pressure expansion area. The separation method is to atomize the waste liquid through the atomization equipment and then vaporize it through the high-temperature airflow to separate the solid particles in the waste liquid from the water, realize the agglomeration of the solid particles through the sound generating device, and then realize the agglomerated solid particles through the static pressure expansion area The accelerated sinking; the gas is discharged through the outlet of the device, so as to achieve the purpose of multi-phase separation. This device achieves the separation effect of solid, liquid and gas by using high-energy sounding device and unique static pressure expansion design.

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...
