A kind of microbubble purification device and method

Abstract

The invention relates to a microbubble purification device and method. After the gas enters the purification device, it is evenly distributed under the action of the first layer of gas distributor, and enters the purification chamber through the hole of the gas distributor to form relatively small liquid bubbles. As it rises, most of the dust is captured in contact with the liquid film of the bubble wall in the bubble. After passing through the second layer of gas distributor, the speed of the liquid bubble passing through the plate hole is increased, the cutting effect on the liquid bubble is strengthened, the liquid bubble is further broken, and dust-catching microbubbles are formed; when the liquid bubble is cut by the second layer of distributor, the cavitation effect of ultrasonic waves And mechanical action, the surface wall of the microbubble forms high-frequency vibration, some microbubbles are further fragmented, and the surface vibration of some microbubbles strengthens the contact probability between the liquid film and the dust, increases the contact frequency between the smoke and the bubble wall, and strengthens the gas-liquid mixed effect. Finally, the fine dust in the flue gas is in full contact with the wall of the purification bubble, which reduces the probability of escape and achieves the purification effect of the fine dust.

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
