Micro-bubble purifying apparatus and micro-bubble purifying method

Abstract

The invention relates to micro-bubble purifying apparatus and a micro-bubble purifying method. When gas enters the micro-bubble purifying apparatus, the gas is uniformly distributed under the action of a first-layer gas distributor, and enters a purifying chamber through holes of the first-layer gas distributor so as to form relatively tiny liquid bubbles; and then, the liquid bubbles ascend so asto capture most of dust due to contact of the dust with liquid membranes of liquid bubble walls of the liquid bubbles. When the gas passes through a second-layer gas distributor, speed of the liquidbubbles passing through plate holes increases, so that cutting effects on the liquid bubbles are enhanced so as to further break the liquid bubbles to form dust-capturing micro-bubbles; at the same time, cavitation effects and mechanical actions of ultrasound are utilized when cutting is performed on the liquid bubbles by the second-layer gas distributor, so that high-frequency vibration acts on surface walls of the micro-bubbles to break part of the micro-bubbles further; and thus, contact rate of the liquid membranes with particulates is increased due to vibration of surfaces of part of themicro-bubbles, so that contact frequency of smoke with the liquid bubble walls is improved so as to enhance gas-liquid mixing effects. Finally, fine dust in the smoke fully contacts with purifying liquid bubble walls so as to reduce escape probability, so that purification effects on fine dust is achieved.

Description

technical field [0001] The invention relates to a micro-bubble purification device and method for physical mixing of smoke and purification liquid, which can achieve the mixing of gas and liquid to the level of micro-bubbles, and strengthen the effective purification of fine dust in flue gas; it is suitable for small processing capacity, fine smoke and dust Purification, such as household air purification, kitchen oil fume purification, small flow industrial dust purification. Background technique [0002] Gas-liquid contact mixing can mix harmful flue gas and purification liquid to achieve the purpose of absorbing harmful dust in the gas and purifying the gas. It can be used for household air purification and air quality control in public places (such as air purification in smoking rooms, etc.). [0003] The traditional gas-liquid mixing device absorbs and purifies the flue gas by impacting the liquid surface with the flue gas, atomizing the purification liquid or generati...

Problems solved by technology

However, the volume of the capture body produced by the traditional method is too large, the contact area between the capture body and the flue gas is too small, and the contact opportunity is small, resulting in the escape of fine dust
