Abstract

The invention relates to the technical field of nanobubble generation, in particular to a micro-nanobubble continuous generation control method, system and device. The problems that a gas-liquid mixing pump is high in cost, needs an air pump, is large in noise and is limited in application are solved. The device comprises a water pump, a water inlet valve, a vent valve, a water outlet valve, a first pressure dissolved air tank, a second pressure dissolved air tank and an nth pressure dissolved air tank, the water pump is respectively connected with the first pressure air dissolving tank, the second pressure air dissolving tank to the nth pressure air dissolving tank through a plurality of water inlet valves; the top of each pressure dissolved air tank is communicated to the vent valve, and the bottom is communicated to the water outlet valve. The method comprises the following steps: acquiring the number and residual volume of dissolved air tanks, and starting a dissolved air tank switching program and a water production program to form micro-nano bubble water; collecting the generated micro-nano bubble water, and carrying out sampling detection on the micro-nano bubble water; continuous and stable production is achieved, the production efficiency is improved, continuous supply of bubble water is ensured, additional air pump equipment is not needed, and energy conservation and emission reduction are facilitated.
