Micro nano bubble generator

Abstract

The invention discloses a micro nano bubble generator which comprises a water intake pipe and a drainage pipe; one end of the water intake pipe is connected with a booster pump; the other end of the booster pump is connected with the top part of an air saturator in a sealing manner through a pipeline; an electromagnetic flowmeter is arranged on the pipeline; the top part of the air saturator is communicated with an air intake pipe in a sealing manner; an electromagnetic valve arranged on the air intake pipe is arranged in a control cabinet; an ejector nozzle, an ejector throat chamber, a liquid level floating ball, an air dissolved water absorption pipe are arranged in the air saturator; the ejector nozzle is connected with a pipeline; the ejector throat chamber is arranged on a position matched with the lower side of the ejector nozzle; an air liquid cavity is arranged between the ejector nozzle and the ejector throat chamber; a switch of the electromagnetic valve is controlled by a programmable controller; and the air dissolved water absorption pipe extends to the outside of the air saturator and is connected with the drainage pipe. The micro nano bubble generator can effectively remove dispersible oil uniformly dispersed in the water with an oil drop grain diameter equal to or less than 10 Mu m; meanwhile, oxidation desulfurising treatment on oily sewage or dissolved oxygen treatment by adding nitrogen is realized based on improving the air floatation oil by using different air source types.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to a micro-nano bubble generator. Background technique [0002] In the treatment of oily sewage, the commonly used method is the air flotation purification method. The so-called air flotation method uses the action of microbubbles, coagulants and flocculants to condense the oily substances and suspended solids in the oily sewage, and then floats to the water body. Surface, so as to achieve a method of separating the dirt and then removing the dirt through the sewage discharge equipment. Microbubbles are a general term for bubbles with a diameter of less than 50 μm. The generation of microbubbles is mainly realized by the method of inhaling and pressurizing before the pump to dissolve or inhaling air into the water in the form of an aerator, and then making bubbles through the high-speed rotation of the impeller. The diameter of the bubble particles generated during the operation of ...

Problems solved by technology

In addition, the previous equipment only used air as the gas source, which was mixed with water to generate microbubbles

The operation processing effect is too simple
