Embodiment Construction
[0017] The specific embodiments of the present invention will be described in more detail below in conjunction with the schematic diagram. According to the following description and claims, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and all use imprecise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0018] figure 1 Is a schematic diagram of a micro bubble generator provided by an embodiment of the present invention, see figure 1 As shown, the micro-bubble generator includes an outer tube 1, an air duct 2 and a flow guide tube 3. The outer tube 1 includes a swirling section 101, a transition section 102, a necking section 103 and a diverging section connected in sequence 104. The inner cavity of the swirling section 101 is cylindrical, the inner cavity of the transition section 102 and the in...

The invention discloses a micro bubble generator, which comprises an outer sleeve, a gas-guide tube and a flow guide tube. The outer sleeve comprises a swirling section, a transition section, a necking section and a diffusion section which are connected in sequence; the inner diameter of the necking section is smaller than that of the swirling section; the gas-guide tube comprises a leading-in section and a reducing section, the reducing section is arranged in the necking section, air holes are formed in the tube wall of the reducing section, the leading-in section is arranged in the swirlingsection and connected to the reducing section, the flow guide tube and the swirling section are connected in a crossed mode, and the axis of the flow guide tube and the axis of the swirling section are on different planes. According to the micro bubble generator provided by the invention, liquid enters the necking section around the leading-in section in a high-speed rotating state, gas in the reducing section is mixed with the liquid through the air holes, and the liquid repeatedly shears and crushes the gas so as to generate a large number of ultra-micro bubbles.
Description
Technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a micro-bubble generator. Background technique [0002] According to the generation principle, the ultra-micro bubble generation technology can be divided into multiple technical methods such as pressurized dissolved air degassing method, dispersed air method, jet aeration, ultrasonic cavitation method and electrolysis method. The main principle of the dispersed air method is to use The shearing force is formed by hydraulic shearing, high-speed swirling, etc., and an extreme condition is created. The air is repeatedly sheared and broken, so that it is mixed with water to generate a large number of micro-nano bubbles. At present, there are many ultra-micro bubble generators, but they are often complicated in structure, difficult to manufacture, and high in cost of finished products, which is not conducive to popularization. Moreover, most products often only consider ...
