Problems solved by technology

[0002] At present, there are many air flotation methods used in industrial water treatment, such as dissolved air flotation, jet air flotation, swirl air flotation, and vortex air flotation, all of which have single functions and poor separation effects; High, the separated oil is residual oil, containing many chemicals and impurities, difficult to handle, not convenient for direct recycling, and difficult to promote
[0003] In order to solve this problem, make the oil-water separation more functional, better effect, simple and practical, do not add medicine in the whole process, and prevent chemical pollution, a Chinese patented multifunctional centripetal air flotation and electrode chemical combination device (Patent No.: 2013 20198353.8), although a certain degreasing effect has been seen, the problems of low degreasing rate and poor oil-water separation effect have not been solved because the focus is on single vortex centripetal air flotation degreasing

Embodiment Construction

[0018] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] A method of turbulent air flotation oil-water separation. Firstly, a pump is used to lift and pressurize the oily sewage, and the pressurized oily sewage is then pressure-dissolved with air. , the air bubbles are small (<10µm), and the effect is good, making the air bubbles completely adhere to the oil beads. When the oily sewage after dissolved air passes through the spray orifice plate, under the action of negative pressure, the large oil droplets suspended in the sewage are due to the large number of adsorbed air bubbles, and...

Abstract

The invention discloses a turbulent air floatation oil-water separation method, which comprises multi-channel jet negative pressure oil removal, vortex centrifugal oil removal and micro-vortex micro-rotary floatation oil removal. Suspended oil, dispersed oil and emulsified oil in water are separated and removed together by using the above three separation principles. The method has many functions,strong pertinence and good effect. In the operation process, only air is added, no medicine is added, the method is green and environment-friendly, safe and pollution-free, and the separated oil is pure oil, does not contain medicines and impurities, is convenient for direct recycling and has obvious synergy.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for separating oil and water by turbulent air flotation. Background technique [0002] At present, there are many air flotation methods used in industrial water treatment, such as dissolved air flotation, jet air flotation, swirl air flotation, and vortex air flotation, all of which have single functions and poor separation effects; High, the separated oil is residual oil, which contains many chemicals and impurities, is difficult to handle, is not convenient for direct recycling, and is difficult to promote. [0003] In order to solve this problem, make the oil-water separation more functional, better effect, simple and practical, do not add medicine in the whole process, and prevent chemical pollution, a Chinese patented multifunctional centripetal air flotation and electrode chemical combination device (Patent No.: 2013 20198353.8), although a certai...
