Abstract

The invention discloses a fuzzy control system of a micro-nano bubble generating device, the fuzzy control system is used for controlling the micro-nano bubble generating device to work, the micro-nano bubble generating device comprises a micro-nano bubble generating mechanism, a regulating valve and a water pump. The regulating valve is arranged on a connecting pipeline between the water pump and the micro-nano bubble generating mechanism; the fuzzy control system comprises a signal acquisition module, a central processing unit which is used for calculating fuzzy control input quantity, a fuzzy control module which is in data connection with the central processing unit, and a PID module which is in data connection with the fuzzy control module. According to the fuzzy control system and control method of the micro-nano bubble generating device, when water pressure fluctuates and gas-liquid two-phase exchange fluctuates, the size of the regulating valve and the rotating speed of the water pump are controlled through fuzzy control, the control convergence is good, and the morphological characteristics generated by micro-nano bubbles have good consistency.

Description

technical field [0001] The invention relates to the technical field of micro-nano bubble generating equipment, in particular to a fuzzy control system of a micro-nano bubble generating device. Background technique [0002] Usually, bubbles with a diameter of ten to tens of microns in water are called microbubbles, bubbles with a size of hundreds of nanometers or less are called nanobubbles, and the mixed state of bubbles existing in the middle of both sides is called micronano bubbles. The physical and chemical properties of this kind of micro-nano bubbles as small as ten microns will undergo fundamental changes, and they have the advantages of strong adsorption capacity for suspended matter, long residence time, good stability, large surface area, and high mass transfer efficiency. Therefore, micro-nano bubbles are widely used in the field of water treatment technology, such as industrial fields such as oily wastewater treatment, fish farming, and household fields such as h...
