A micro-nano bubble generating system

Abstract

The invention discloses a micro-nano bubble generating system comprising a first pressure pump, the first pressure pump is connected with a first water inlet pipe and a first water outlet pipe, and the end of the first water outlet pipe away from the first pressure pump is connected with a mixing The mixing tank is connected with a second water outlet pipe; the first water inlet pipe is provided with an air inlet part, and the first water inlet pipe is provided with an adjustment valve, which is used to control the water flow in the first water inlet pipe; the first water inlet pipe is connected with There is a second water inlet pipe, the end of the second water inlet pipe away from the first water inlet pipe is connected with a second pressure pump, the second pressure pump is connected with the first water outlet pipe through the third water outlet pipe; the second water inlet pipe is connected with the return pipe through the return pipe. The second water outlet pipe is connected, and the water return pipe is provided with a second one-way valve, which prevents water from flowing from the first water inlet pipe to the second water outlet pipe through the return water pipe. The micro-nano bubble generation system provided by the invention improves the service life of the pressurizing pump and the generation efficiency of the micro-nano bubbles.

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 micrometers to hundreds of nanometers when they occur. These bubbles are between micro-bubbles and nano-bubbles and have physical and chemical properties that conventional bubbles do not have. Micro-nano bubbles have the characteristics of large specific surface area, slow rising speed, self-pressurized dissolution, surface charging, 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] Micro-nano bubbles themselves do not carry the function of killing bacteria. However, upon bursting of the bubbles, hydroxyl radicals are generated, which can complete the bacterial killi...

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
