Micro-nano bubble generating device

Abstract

The invention discloses a micro-nano bubble generating device. The device comprises a water inlet pipe, and a first flow meter, a water pump and a first electric control valve are installed on the water inlet pipe; an inner ring cavity is formed in the water inlet pipe, and a plurality of air outlets are uniformly distributed in the inner ring cavity; the inner ring cavity is communicated with anair inlet pipe, and an air pump, a second flow meter and a second electric control valve are mounted on the air inlet pipe; the water inlet pipe and the air inlet pipe are both communicated with a spiral mixing pipe, and the spiral mixing pipe is communicated with a pressurizing pipe; and the inner diameter of the pressurizing pipe is gradually reduced from two sides to the middle part. The deviceis simple in structure and convenient to use, the ratio of water to air can be automatically adjusted, the micro-nano sparkling water can be stopped when used, and the micro-nano sparkling water canbe continuously generated.

Description

Technical field: [0001] The invention belongs to the field of machinery, in particular to a micro-nano bubble generating device. Background technique: [0002] Microbubbles are tiny bubbles with a diameter of less than 50 microns (μm) produced when bubbles occur, and can also be called micro-nano bubbles, micro-bubbles or nano-bubbles according to their diameter range. At the moment when the micro-nano bubbles burst, due to the dramatic change of the disappearance of the gas-liquid interface, the high-concentration ions accumulated on the interface will release the accumulated chemical energy at once, and at this time, a large number of hydroxyl radicals can be excited. Hydroxyl radicals have an ultra-high oxidation-reduction potential, and the super-strong oxidation produced by them can degrade pollutants that are difficult to oxidize and decompose under normal conditions in water, such as phenol, to achieve water purification. Therefore, it can be used for people's daily ...

AI Technical Summary

Problems solved by technology

However, the existing micro-bubble generating device usually mixes water and air and pressurizes, so that the gas is pressed into the water to form micro-nano bubbles, which has low efficiency, high energy consumption, and cannot continuously generate micro-nano bubbles.
