Water treatment field.Meanwhile, the raw material price needed for Fenton's reaction is cheap, and buying is easy, therefore is obtained extensively in wastewater treatment industry
General use.
, it is necessary to be stirred, to strengthen Fe during Fenton's reaction progress2+With H2O2Mixing.Because Fenton's reaction is profit
Oxidation reaction is carried out with hydroxyl radical free radical, and the life-span of hydroxyl radical free radical is extremely short, in the life span of hydroxyl radical free radical
If not reaching pollutant, hydroxyl radical free radical waste is will result in, therefore, in Fenton's reaction equipment, stirring mass transfer is unusual
It is crucial, important.Strong stirring, can strengthen Fe2+With H2O2With the mixing mass transfer of waste water, increase hydroxyl radical free radical and pollutant
Contact probability, accelerate Fenton's reaction oxidized waste water in organic matter oxidation rate.Stirring in conventional Fenton's reaction equipment
Device is that motor drives an agitating paddle to be stirred.Agitating paddle shape is often two blades or three-vaned individual layer or double-deck stirring
Oar, material is often stainless steel.Such a agitating paddle shape is relatively simple, and stirring mass-transfer efficiency is relatively low, and capacity usage ratio is not high.Reach
Under the target stirred, the electrode power of selection is larger, causes power consumption higher.
The content of the invention
In order to overcome the above-mentioned equipment of Fenton's reaction in the prior art stirring mass-transfer efficiency relatively low, oxidation rate is slower, energy consumption
Serious, elapsed time is long, and the clearance for the Organic substance in water that gives up is low, the shortcomings of causing discharge beyond standards, the purpose of this utility model
It is that providing a kind of reinforcing Fenton's reaction mixes equipment, mixing is strong, and reaction effect is good.
To achieve these goals, the technical solution adopted in the utility model is：
One kind reinforcing Fenton's reaction mixes equipment, including cavity 2, and water inlet 1 is arranged at the bottom of cavity 2, and top has
There is a vertical agitator mouth of a river 6, inside, and the agitator includes agitating shaft 4, is arranged on stirring for coaxial line on agitating shaft 4
Mix cylinder 8 and be arranged on the stirring blade 3 of the staggeredly hollow out of stirring cylinder 8 outer surface.
The lower end of the agitating shaft 4 is arranged in the blender base 7 of the bottom of cavity 2, and upper end is by shaft coupling with slowing down
The output connection of motor 5.
The stirring cylinder 8 is enclosed on agitating shaft 4, is connected by way of welding or pin.
The stirring blade 3 has 3~6, by welding or screw fixed form, is circumferentially uniformly arranged on stirring cylinder
On 8 wall.
The stirring blade 3 is perpendicular to the stirring tangent line of cylinder 8.
Uniform concavo-convex interphase structure is presented in the stirring blade 3 in the longitudinal direction, and recessed portion is openwork part 9,
It is non-openwork part 10 at lower concave part tap agitating shaft 4, projection carries out hollow out, including openwork part 9 and remote agitating shaft 4
Non- openwork part 10, the adjacent area of openwork part 9 and shape be equal, the adjacent area of non-openwork part 10 and shape phase
Deng.The radius of the stirring cylinder 8 is 2 with the ratio of the outermost radical length of blade 3 is stirred:1 to 4:1.
The radical length ratio of the hollow-out parts 10 and non-hollow-out parts 9 is 0.5：1 to 2:1.
Stirring blade 3 main body is frame blade shape.
Compared with prior art, the utility model is using the agitator type of optimization, and mixing tool simultaneously radially cut by offer
The ability of shear force and normal direction shearing force, in high-speed stirred, enabling in reactor waste water, diametrically (section) is obtained more
Strong mixed effect.
The blade form that the utility model agitator is interspersed, releasable axle upwards pressure, and reduces axially upper mixed flow
With the phenomenon of back mixing, ideal piston flow is presented when making waste water by reactor.

Embodiment
Describe embodiment of the present utility model in detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of reinforcing Fenton's reaction mixes equipment, including cavity 2, the bottom of cavity 2 have into
Delivery port 6 arranged at the mouth of a river 1, top, and there is a vertical agitator inside, and agitator includes agitating shaft 4, stirring cylinder 8 and staggeredly hollow out
Stirring blade 3.
Wherein, the lower end of agitating shaft 4 is arranged in the blender base 7 of the bottom of cavity 2, and upper end is by shaft coupling with slowing down
The output connection of motor 5, reducing motor 5 is located at reactor head, the stirring in reactor is imparted power to by shaft coupling
Device 4.
Stirring cylinder 8 is enclosed on agitating shaft 4, and the two coaxial line is connected by way of welding or pin.Stirring blade 3 has 3~
6, by welding or screw fixed form, on the wall for being circumferentially uniformly arranged on stirring cylinder 8, with the stirring tangent line of cylinder 8
Vertically.
As shown in figure 3, uniform concavo-convex interphase structure is presented in the stirring blade 3 in the longitudinal direction, recessed portion is
Openwork part 9, the bottom of recessed portion is non-openwork part 10, and projection carries out hollow out, including openwork part 9 and non-hollow out
Part 10.
It is 2 to stir the radius of cylinder 8 and the ratio of the stirring outermost radical length of blade 3:1 to 4:1.Hollow-out parts 10 with
The radical length ratio of non-hollow-out parts 9 is 0.5：1 to 2:1.
According to above structure, waste water enters from the water inlet 1 of bottom, in cavity by high-speed stirred agitator shearing and
Mixing, flows out after reactor from delivery port 6.
Because the stirring main body of blade 3 is frame blade shape, so there is provided the shearing force of radial direction；Engraved again because it is used
Empty structure, rotation when, part water flows away from hollow out, therefore there is more strong tangential shearing force.Therefore, agitator
There is the ability for providing tangential shearing force and radial shear power simultaneously on section.
Overall stirring blade 3 is frame mode there is provided centrifugal force, from blade inboard water can be thrown into outside, staggeredly
The blade form of distribution, result in actually adjacent two blades and different centrifugal force is directly presented, water velocity is inconsistent, enters
And adjacent fluid pressure is different, final release shaft upwards pressure, and reduces mixed flow and back mixing phenomenon in a wide range of, leads to waste water
Ideal piston flow is presented when crossing reactor.
