Gas-liquid entrainment mixing apparatus and method

Abstract

The invention relates to a gas-liquid entrainment mixing apparatus and method. The invention relates to an apparatus and a method for physically mixing smoke and purified liquid, which solves the problems in a gas-liquid contact way that the airflow impacts the liquid surface that the gas and liquid are insufficiently mixed due to the intermittent and paroxysmal stimulation of the purified liquid trapping body. When the airflow impacts the liquid surface, the stability of the liquid surface of the purified liquid is adjusted by virtue of a liquid phase flow stabilizing apparatus and a two-phase flow guide apparatus, the high-frequency stimulation of the purified liquid trapping body is adjusted by virtue of the gaseous distributing and pressurizing apparatus and the two-phase flow guide apparatus, a gas-liquid mixing space is controlled by virtue of an entrainment cavity and the two-phase flow guide apparatus, the gas-liquid entrainment and mixing effect is improved, finally the gas and liquid in a purification cavity can be sufficiently mixed, harmful components in the harmful gas can contact with the purified liquid sufficiently, the leakage probability of the harmful components can be reduced, and the purification efficiency can be improved.

Description

technical field [0001] The invention relates to a device and method for physical mixing between flue gas and purification liquid, specifically a gas-liquid entrainment mixing device and method, which can make the gas-liquid two-phase stable entrainment mixing effect, and strengthen the purification liquid The purification effect on harmful substances in the flue gas is suitable for the treatment of respirable dust, SO 2 , ammonia and other harmful flue gas purification. Background technique [0002] Gas-liquid contact mixing is an important way to complete the purification by mixing harmful flue gas and purification liquid. It can deal with high humidity, high temperature and waste gas containing sulfide, ammonia, smoke and so on. It is a commonly used method for flue gas purification in high-emission industries such as traditional mining, metallurgy, chemical industry, cement, and industrial kilns; as flue gas emissions become more and more stringent, flue gas emissions fr...

AI Technical Summary

Problems solved by technology

However, during the operation of the existing equipment, there is no effective control of the fluidity of the gas phase and the liquid phase, so that the process of stimulating the purification liquid by the harmful air flow has obvious paroxysmal and intermittent characteristics, and a Larger ineffective contact space is created, and the effect of full gas-liquid mixing cannot be achieved, which provides possible time and space for the escape of harmful substances in the airflow, and the overall purification efficiency is reduced
