Abstract
The invention discloses a rotary defoaming aerator, comprising an aerator body. multiple segments or a circle of defoaming tubes are disposed on the peripheral wall of the aerator body; the defoaming tubes are provided with a plurality of defoaming tube water outlets arranged at equal intervals; axes of the defoaming tube water outlets are an included angle A related to the horizon, with A valued from 0 degree to 30 degrees. The rotary defoaming aerator further comprises a rotator; the rotator comprises a motor; one end, far away from the rotor, of a rotary output shaft of the motor is sleeved with a rotary disc; the rotary disc is connected to the deforming tubes through connecting posts. During aeration, foam forms in the middle of the aerator, continuously moves to the edge of the aerator and gathers at the edge of the aerator. The defoaming tubes are disposed on the peripheral wall of the aerator, water sprayed from the deforming tube water outlets impacts on the foam, and the foam is thereby eliminated; therefore, by horizontally or obliquely setting the defoaming tube water outlets, generally oblique setting, the effect is better.
Description
Technical field
The present invention relates to environmental technology field, specifically rotary froth breaking aeration tank.
Background technology
Aeration tank passes into the waste disposal plant in air to sewage lagoon, sewage being carried out to Air Exposure, in the process of Air Exposure, often can produce a large amount of foams, for above-mentioned foam, generally do not process it or adopt defoamer to process.The major cause of bubbling there is partial chemical product composition in waste water.This kind of chemical component is cut into small molecules under the hydraulic shear effect that low pressure stream aerating system is stronger, in conjunction with tiny bubble thus formed foam.Foam to there is hazard ratio comparatively large, flowing out as taken partial sludge out of, easily making sludge reflux amount large, increasing cost; Reduce oxyty, be unfavorable for the growth etc. of aerobic flora; And to solve the method for foam be add defoamer in the aeration tank of routine, and for most sewage, the chemical component of its inside is complicated, and the chemical component in sewage is comparatively large on the impact of defoamer, and therefore, the result of use of defoamer is also not obvious.
Summary of the invention
The object of the present invention is to provide a kind of rotary froth breaking aeration tank, this device utilizes the pipeline loading water spray on aeration tank, the High-Pressure Water utilizing pipeline to spray breaks up foam, thus eliminates a large amount of foams, and this effect is more obvious than using the defoaming effect of defoamer.
Object of the present invention is achieved through the following technical solutions: rotary froth breaking aeration tank, comprise aeration tank, the surrounding pool wall of aeration tank is provided with the froth breaking pipe of multistage or a circle, froth breaking pipe is provided with some equally spaced froth breaking pipe posticums, angle between the axially bored line of froth breaking pipe posticum and horizontal plane is that the span of A, A is at 0 degree to 30 degree.Also comprise swivel arrangement, swivel arrangement comprises motor, and the rotating output shaft of motor is arranged with rotating disk away from one end of motor, and rotating disk is connected on froth breaking pipe by joint pin.
Due in aeration, foam is formed and constantly to move to aeration tank fringe region in the middle part of aeration tank, and the fringe region in aeration tank is assembled, therefore the present invention arranges froth breaking pipe on the surrounding pool wall of aeration tank, current are ejected from froth breaking pipe posticum, use water impact foam, thus by the removal of foam, because general foam is bubbled through the water column, highly general at below 5cm, therefore froth breaking pipe posticum is horizontally disposed with or is obliquely installed by the present invention, the effect be generally obliquely installed is better, can the span of control A at 0 degree to 30 degree, higher defoaming effect can be reached.When starter motor, the rotating output shaft driven rotary dish of motor carries out synchronous rotary motion, because rotating disk is connected on froth breaking pipe by joint pin, therefore froth breaking pipe can be driven to be rotated around rotating output shaft axis, in rotary motion, the current of injection can eliminate foam faster.
The reduction aeration intensity that the present invention is all right suitable, utilizes waterpower to break up foam (water is the effluent reuse of final deposition pool).Operation result shows, and foam is significantly controlled.
Preferably.The value of A is 15 degree.Or the value of A is 10 degree.Or the value of A is 0 degree.Or the value of A is 30 degree.Or the value of A is 15 degree to 30 degree.
Preferably.Blow-off pipe, aeration tube, water inlet pipe is also provided with bottom described aeration tank.
Preferably.When froth breaking Guan Weiyi encloses, froth breaking pipe is ring pipe or rectangular pipe.
Preferably.When froth breaking Guan Weiyi encloses, the shape of froth breaking pipe is formed with aeration tank inwall mates.
The invention has the advantages that: structure is simple, and cost is low, simple and quick, and defoaming effect is obvious.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1:
As shown in Figure 1 and Figure 2 and Figure 5, rotary froth breaking aeration tank, comprise aeration tank 1, the surrounding pool wall of aeration tank is provided with the froth breaking pipe 2 of multistage or a circle, froth breaking pipe 2 is provided with some equally spaced froth breaking pipe posticums 3, angle between the axially bored line of froth breaking pipe posticum 3 and horizontal plane is that the span of A, A is at 0 degree to 30 degree.
Due in aeration, foam is formed and constantly to move to aeration tank fringe region in the middle part of aeration tank, and the fringe region in aeration tank is assembled, therefore the present invention arranges froth breaking pipe on the surrounding pool wall of aeration tank, current are ejected from froth breaking pipe posticum 3, use water impact foam, thus by the removal of foam, because general foam is bubbled through the water column, highly general at below 5cm, therefore froth breaking pipe posticum 3 is horizontally disposed with or is obliquely installed by the present invention, the effect be generally obliquely installed is better, can the span of control A at 0 degree to 30 degree, higher defoaming effect can be reached.
