Description
Technical field
The present invention relates to a kind of Hydrodynamic cavitation oxygenation aerator, when it belongs to a kind of sewage biochemical treatment in water efficient oxygenation aeration, utilize the Hydrodynamic cavitation effect that produces simultaneously, directly the device of organic pollution materials in the degradation water.
Background technology
Blast aeration or mechanical aeration oxygenation in water is generally adopted in the sewage biochemical treatment; Mechanical aeration is oxygenation in water, utilizes the rotation of equipment such as impeller, and the vigorous stirring water surface dissolves in air in the water; The mechanical aeration device structure is simple; But the impeller table area is limited, can not impeller do very big, so its oxygen-transfer efficiency is restricted.Blast aeration is made up of pressure exerting device and dispersion device; Form the size of bubble according to aeration, blast aeration is divided into types such as air pocket, middle bubble, small bubbles and microbubble, the atmosphere very fast buoyance lift that ducks in drink; Constantly enlarge, constantly reduce with the conversion area that contacts of water, oxygen-transfer efficiency is low.The micro-bubble dispersion device pressure-losses is bigger, is prone to stop up.Because aerating system energy consumption proportion in WWT is huge, how improving aerating system efficient is the target that people pursue always.
Someone adopts the jet dispersion device, or strengthens gas-to-liquid contact through curved slab is set in the pipeline, improves the oxygenic aeration ability.These devices in use can't overcome the aeration dead angle, or the physical construction easy blocking causes use inconvenience.
Summary of the invention
The objective of the invention is to solve the aeration dead angle of existing aerating apparatus existence and the technical problem of easy blocking, provide a kind of aeration not have dead angle, the difficult Hydrodynamic cavitation oxygenation aerator that stops up and can greatly improve aerating system efficient.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: Hydrodynamic cavitation oxygenation aerator; Comprise motor and transmission shaft; Wherein: it also comprises upper end cover, helical stir impeller, taper porous spoiler and oxygenation aeration cylindrical shell; Motor be contained in upper end cover above, the axis hole that motor shaft passes upper end cover connects with the upper end of transmission shaft, the lower end of transmission shaft connects with the helical stir impeller; Motor is contained in the top of oxygenation aeration cylindrical shell and transmission shaft and helical stir impeller is arranged in the inner chamber of oxygenation aeration cylindrical shell through upper end cover, taper porous spoiler be located at the bottom of oxygenation aeration cylinder intracoelomic cavity and be positioned at the helical stir impeller below.
Bottom at said oxygenation aeration cylindrical shell is provided with the reflection guide shell.
Said taper porous spoiler is provided with several tapered openings of at least one row, and several tapered openings are evenly distributed on the taper porous spoiler.
Said upper end cover is a projective table type flange shape; Central authorities at upper end cover are provided with a through hole; On the anchor ring of the big ring platform of upper end cover, evenly be provided with several bolts hole; Upwards evenly be provided with four grooves in the footpath of upper end cover boss face with as the passage that sucks air, on the upper end cover boss face, also evenly be provided with four screw holes that connect with motor.
Said helical stir impeller is made up of three leaf taper paddles at least, and 55～70 ° and bending are vertically downward worn in the paddle tip.
Because taper porous spoiler of the present invention is divided into chamber behind plate cup and the plate with oxygenation aeration cylindrical shell; The helical stir impeller is high speed rotating under the drive of motor, and the agitated liquid high speed rotating also produces downward thrust, releases the liquid at high speed of plate cup downwards; Form four the grooves suction air of hole from upper end cover; Inhaled air is brought in the eddy current under the effect of helical stir impeller high speed rotating, and the air of bringing in the eddy current forms a large amount of micro-bubbles in water, and these micro-bubbles penetrate at a high speed through the tapered openings on the taper porous spoiler; It is big that flow velocity becomes, and pressure further reduces; , pressure can produce a large amount of cavitation bubbles when reducing to the cavitation inception pressure, directly the organic pollution materials in the degradation of sewage.Therefore, compare with background technology, the present invention has aeration and does not have the dead angle, be difficult for to stop up and can greatly improve advantages such as aerating system efficient.
