Description

Technical Field

[0001] The utility model relates to the technical field of bubble generators, in particular to a flat-plate bubble generator. Background Art

[0002] The tiny bubbles existing in the liquid are called micron bubbles when the bubble diameter is below 100μm, and the bubbles with a diameter of less than 100nm are called nano bubbles. Micro-nano bubbles refer to bubbles with a diameter between tens of microns and hundreds of nanometers when bubbles occur. This type of bubble is between micron bubbles and nano bubbles, and has physical and chemical properties that conventional bubbles do not have. The bubble generator uses cross-flow filtration, and the water flow generates two components of force on the membrane surface. One is the normal force perpendicular to the membrane surface, which allows water molecules to pass through the membrane surface, and the other is the tangential force parallel to the membrane surface, which washes away the retained substances on the membrane surface.

[0003] When the flat-plate bubble generator is in use, due to the different operating environments of the generator, there will be different degrees of dirt in the water. The generator cannot intercept larger dirt, and although smaller dirt can be cleaned by cross-flow, when the dirt accumulates on the membrane surface, the flat-plate bubble generator is inconvenient to open and close, which makes it inconvenient to clean the membrane surface. Therefore, a technician in this field provides a flat-plate bubble generator to solve the problems raised in the above background technology. Utility Model Content
