Problems solved by technology

Careful investigation may have two reasons: On the one hand, the radial dimension of the liquid flow channel must increase correspondingly when the raw water treatment capacity increases. Gas pressure, resulting in high gas consumption and low gas utilization rate, and the possibility of larger particle size bubbles is greatly increased; on the other hand, when the micro-bubble generator is out of service for a period of time Scaling and clogging will inevitably occur in the produced internal concentric tubes, but the cleaning, maintenance and disassembly process is relatively cumbersome

Abstract

The invention discloses a micro-bubble generation device based on a plate type microporous medium foaming mechanism. The micro-bubble generation device comprises a pipe-column-shaped outer barrel body, wherein the upper end and the lower end of the outer barrel body are sealed with flange covers respectively, two independent air chambers are formed in parts close to two side walls in the outer barrel body, and the other cavity in the outer barrel body is a water flow chamber; a conical flow guide barrel is arranged at the upper part of the water flow chamber, the space in the upper part of the conical flow guide barrel is a rotational-flow cavity, a tangential water inlet pipe is arranged on the wall of the outer barrel body at the rotational-flow cavity, and a water outlet pipe is arranged on the wall at the lower part of the outer barrel body; air inlet pipes are arranged on the walls of the outer barrel body at the air chambers, and rectangular microporous plates are arranged between the air chambers and the water flow chamber. The micro-bubble generation device is high in utilization rate of air, large in handling capacity and convenient to dismount, and is mainly used for providing a large quantity of micro-bubbles for water quality air flotation purification treatment or other process with full air-liquid contact requirement.

Description

technical field [0001] The invention relates to a micro-bubble generating device, in particular to a micro-bubble generating device based on the foaming mechanism of a plate-type microporous medium. Background technique [0002] Air flotation technology is to inject a large number of highly dispersed micro-bubbles into the water to be treated, so that the micro-bubbles collide with particulate pollutants (such as suspended solids (SS), oil droplets, etc.) and then float to the water surface by buoyancy to form The scum is removed to realize sewage purification. Air flotation technology first appeared in the beneficiation industry, and is mainly used to remove impurities in ore or for mineral beneficiation or flotation. Later, with the gradual development of air flotation technology, C.L.Peck first proposed the idea of ​​using it for sewage treatment in 1920. However, due to the limitation of micro-bubble generation technology, the air flotation technology did not really de...
