Abstract

The invention relates to a spiral-flow type micro bubble generator and a micro bubble generation method, and belongs to a plurality of fields of ore dressing, wastewater treatment, waste paper deinking, aquatic products breeding and transportation, and the like. The spiral-flow type micro bubble generator includes three kinds of structures such as a self air-suction type structure, a non self air-suction type structure and a mixed flow type structure; the method comprises determining of the flow-in way of a fluid according to the different structure of the spiral-flow type micro bubble generator, and determining of the flow-out way of the fluid according to the different structure of the spiral-flow type micro bubble generator. The spiral-flow type micro bubble generator has the advantages of good air inflation performance and low energy consumption, generated micro bubbles are uniform and reasonable in size distribution; the shape and size of an air inlet or a flow outlet can be changed according to the actual situation to achieve the self suction air in letting and flow out letting at both ends to generate the micro bubbles; the air supply mode can adopt self suction air supply type or pressurized air supply, air is taken into the micro bubble generator in the manner of taking with the fluid, and the spiral-flow type micro bubble generator has the characteristics of simple structure, uneasy blockage and convenient maintenance.

Description

Technical field [0001] The invention relates to a swirling type microbubble generator and a method for generating microbubbles, belonging to the fields of mineral processing, wastewater treatment, waste paper deinking, aquatic product breeding and transportation, and the like. Background technique [0002] Microbubbles are a crucial factor in microbubble flotation. Different flotation requires different sizes and different numbers of microbubbles. How to produce microbubbles suitable for different requirements is the key to the success of microbubble flotation separation. It has been found in practice that it is especially important to produce small and stable microbubbles. [0003] Microbubble flotation itself is a huge innovation in the flotation industry. It has been widely used in many fields such as metal and non-metal mineral processing, wastewater treatment, waste paper deinking, etc. abroad. Microbubble flotation is based on the difference of the surface properties of diff...
