Micro-nano bubble generation system

Abstract

The invention discloses a micro-nano bubble generation system which comprises a first pressure pump, the first pressure pump is connected with a first water inlet pipe and a first water outlet pipe, the end, away from the first pressure pump, of the first water outlet pipe is connected with a mixing tank, and the mixing tank is connected with a second water outlet pipe; the first water inlet pipe is provided with an air inlet part and an adjusting valve, and the adjusting valve is used for controlling the water flow in the first water inlet pipe; the first water inlet pipe is connected with a second water inlet pipe, one end, far away from the first water inlet pipe, of the second water inlet pipe is connected with a second pressure pump, and the second pressure pump is communicated with the first water outlet pipe through a third water outlet pipe; the second water inlet pipe is communicated with the second water outlet pipe through a water return pipe, the water return pipe is provided with a second one-way valve, and the second one-way valve prevents water from flowing from the first water inlet pipe to the second water outlet pipe through the water return pipe. According to the micro-nano bubble generation system, the service life of the pressure pump is prolonged, and the micro-nano bubble generation efficiency is improved.

Description

technical field [0001] The present application relates to the field of micro-nano bubble generating equipment, in particular to a micro-nano bubble generating system. Background technique [0002] Micro-nano bubbles refer to bubbles with diameters ranging from tens of microns to hundreds of nanometers when bubbles occur. This kind of bubbles is between micro-bubbles and nano-bubbles, and has physical and chemical characteristics that conventional bubbles do not have. Micro-nano bubbles have the characteristics of large specific surface area, slow rising speed, self-pressurized dissolution, surface electrification, generation of a large number of free radicals and high gas dissolution rate. Widely used in sewage treatment, environmental protection and fruit and vegetable cleaning and other fields. [0003] The micro-nano bubbles themselves do not carry the function of killing bacteria. However, when the bubbles collapse, hydroxyl radicals will be generated, which can comple...

Problems solved by technology

[0005] During the use of the micro-nano bubble generating equipment, due to the different numbers of water-using equipment and the different water consumption, the pump body is prone to start and stop phenomena during the use process, resulting in low service life of the pump body and low micro-nano bubble generation efficiency. , the volume of micro-nano bubbles produced is small, which cannot meet the treatment efficiency of pollutants in water bodies and the requirements for environmental protection equipment
