Embodiment Construction

[0023] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0024] Such as figure 2 As shown, an air flotation micro-bubble aeration device for petroleum water treatment includes a device main body and an air intake assembly, and is characterized in that: the device main body is equipped with an air intake assembly, and the device main body is sequentially arranged according to the liquid flow direction It is divided into a sewage treatment inlet section 10, an expanding section 11, a mixed-phase section, a shrinking pressurization section 24, an advection section 25, and an expanding diameter decompression release section 19. The advection section 25 is provided with a gas mixing pressure indicator valve. A mixing flow control valve is installed between the advection section 25 and the expanded-diameter decompression release section 19. The air intake assembly includes a sleeve, an air inlet pipe and an ...

Abstract

The invention discloses an air flotation micro-bubble aeration device for petroleum water treatment, which comprises a device main body and an air intake assembly, and is characterized in that: the device main body is divided into a liquid inlet section for treating sewage, a diameter expanding section, mixed-phase section, reduced-diameter pressurized section, advection section, and expanded-diameter decompression release section, the inlet assembly includes a sleeve, an inlet pipe and an outlet pipe, the sleeve is vertically installed outside the mixed-phase section, and the inlet The air pipe is fixed on the sleeve through the air inlet joint, one end of the air outlet pipe extends into the sleeve and is sealed with the air inlet pipe, and the other end of the air outlet pipe extends into the mixed-phase section and is connected with a nano-microporous medium core pipe, The connection between the air outlet pipe and the nano-microporous medium core pipe is a spherical end, and the usage method of the device is also introduced. The invention provides an air flotation micro-bubble aeration device for petroleum water treatment, which can effectively adjust the bubble diameter, bubble group density and uniformity required by industrial air flotation.

Description

technical field [0001] The invention relates to petroleum water treatment equipment, in particular to an air flotation micro-bubble aeration device for petroleum water treatment and a method for using the same. Background technique [0002] The mechanism of microbubble generation in traditional air flotation can be summarized into several categories: dissolved gas (Dissolved Gas) precipitates bubbles, entrained gas (Induced Gas) creates bubbles, microporous media (Micro-porous Media) foaming, shear contact ( ShearContact) foaming, electrolysis (Electrolysis) precipitation bubbles, etc., are all reflected in the current industrial applications, the gas dissolution efficiency is limited, the size of the microbubbles is uneven, the ideal number of bubbles is low, the air flotation is easy to produce dead zones, and the microbubble gas The floating effect is greatly affected by the temperature and pressure fluctuations of the medium; especially in the case of oily sewage treatme...
