Micro-nano bubble generator

Abstract

The invention discloses a micro-nano bubble generator. The micro-nano bubble generator is characterized by consisting of a dissolved air tank, an air pump and a circulating water pump, wherein the upper part of the dissolved air tank is a dissolved air area provided with atomizing water distribution spray nozzles, a valve core and a filler layer; the lower part of the dissolved air tank is a waterstorage area provided with a water inlet pipe, a floating ball liquid level control valve, a micro-nano bubble outlet and a circulating water outlet; the air pump and the circulating water pump are provided with electric cabinets for adjusting the air inlet pressure and circulating time of sparkling water so as to generate micro-nano bubbles with different particle sizes and uniformities. Compared with the prior art, the micro-nano bubble generator disclosed by the invention has the advantages that diameters of bubbles are distributed at micro-nano scale more stably and uniformly, the instantone-time water feeding mount is large, and the condition that the bubbles break and further lose a cleaning effect due to waiting in the generation process of bubble water volume is effectively avoided; the diameters of the bubbles are controllable; the system can stably work and save energy; the micro-nano bubble generator is simple in structure and compact in equipment and can be particularly arranged on a domestic washing machine or a dish washing machine in a miniaturization mode for use.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a micro-nano bubble generator used for household cleaning and equipment cleaning. Background technique [0002] Micro-nano bubbles are currently emerging high-tech. They can be used in household cleaning such as laundry and dishwashing, industrial equipment cleaning, plant planting, aquaculture, and scientific research. At present, the most commonly used micro-bubbles are pressurized dissolved air. Produced by air flotation method, water ejector method and water pump impeller cutting method. The pressurized dissolved air flotation method adopts the method of water inflow, air inflow and water outflow at the same time. The air is dissolved in water under pressurized conditions to reach the air supersaturated state, and then reduced to normal pressure to let the air separate out. Bubbles are released in the water. Although the system is relatively stable, the wat...

Problems solved by technology

The pressurized dissolved air flotation method adopts the method of water inflow, air inflow and water outflow at the same time. The air is dissolved in water under pressurized conditions to reach the air supersaturated state, and then reduced to normal pressure to let the air separate out. Bubbles are released in the water. Although the system is relatively stable, the water intake has to overcome a large pressure. The head of the water pump is high, the power consumption is large, and the stable operation of the system is more complicated to control. The bubbles generated are more micron-sized and less nano-sized. ; while the water ejector method and the water pump impeller cutting method produce relatively large air bubbles, and the system is unstable and difficult to control

[0003] The microbubbles in the prior art are all produced by the principle of hydraulic cavitation, the particle size of the bubbles is uncontrollable, the energy consumption is large, the system is unstable, and the diameter of the bubbles is relatively wide, generally concentrated in the micron level, and less in the nanometer level , even without nano-scale air bubbles, the processing cost is high, the efficiency is low, and it is especially difficult to provide a sufficient amount of sparkling water at one time. Due to the instability of the sparkling water, the continuously released bubble water will burst quickly, resulting in the process of waiting for the amount of bubble water The cleaning effect is lost, which greatly limits the wide application of micro-nano bubble water in the cleaning field
