Abstract

The invention belongs to the technical field of water treatment and relates to a micro bubble generation method and a micro bubble generator. The micro bubble generator comprises a microporous device,a hollow pipe, a rotating joint, a motor, a power output shaft, a driving shaft and an air pump, wherein the motor is connected with the microporous device through the power output shaft and the driving shaft in sequence and drives the microporous device to rotate around the axial direction of the driving device; the air pump is communicated with the microporous device through the rotating jointand the hollow pipe in sequence and inputs gases into the microporous device; the surface of the microporous device is provided with micropores of which the porosity is not lower than 28 percent; thesize of the micropores is 0.01 to 2 mu m; the gases entering the microporous device overflow from the micropores on the surface of the microporous device to form bubbles with particle size of 5 to 100mu m. The invention provides the micro bubble generation method and the micro bubble generator, which have the advantages of low energy consumption, simple structure and capability of stably producing a large amount of high-density micro bubbles with uniform particle size in liquid phase for a long term.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a bubble generating device, in particular to a micro bubble generating method and a micro bubble generator. Background technique [0002] Fine bubbles refer to bubbles with a particle size of 1-200um formed by dispersing gas in liquid through physical and chemical methods. Micro-bubbles are used in sewage treatment, sludge concentration, mineral processing, black and odorous water treatment, health care and other fields. The methods of generation include pressurized dissolved air method, multiphase dissolved air pump method and induction method. [0003] The basic principle of the pressurized gas-dissolving method is: firstly, the air or other gas is dissolved in the raw water to be treated under a certain pressure, and reaches a supersaturated state, and then the pressure of the dissolved gas water is reduced to form the gas dissolved in it. Fine air bubbles. This method...
