Electromagnetism sewage filter device
Technical field
Sewage disposal scope of the present invention, is related to a kind of sewage filter device, more particularly to a kind of electromagnetism sewage filter device.
Background technology
Existing wastewater treatment method is broadly divided into physical treatment process, method of chemical treatment and biological treatment three classes.Physics
Facture is detached by physical action, recycles the undissolved pollutant in suspended state in waste water (including oil film and oil droplet)
Waste water logos can be divided into gravitational separation process, centrifugal separation and sieving retention method etc., but poor processing effect processing time is long;
Method of chemical treatment be by chemically react and effect of mass transmitting come detach, remove in waste water in dissolve, the pollutant of colloidal state or
It is translated into the waste water treatment process of innocuous substance.In method of chemical treatment, based on adding medicament generation chemical reaction
Processing unit, the drawback is that generating secondary pollution to environment;Biological treatment is the metabolism by microorganism, is made in waste water
In the organic pollution of solution, colloid and fine suspended state, the waste water treatment process of stable, harmless substance is converted into, but
Requirement of the biological treatment to the requirement of environment and sewage quality other than with duration has certain limitation.It imitates in magnetic field
It should be able to promote the related chemical reaction in wastewater treatment process and the activity of substance, improve coagulation effect, magnetic treatment makes water
The molecules align of body structure is destroyed, viscosity reduces, permeability enhancing, is reduced filter residue water content, and was improved purification speed.
Suspended matter in the water body touch opportunity under magnetic fields increases, and improves coalescence speed, increases flocculating rate, and magnetic field has and makes
Complicated macromolecular system becomes simple molecular effect, puies forward high molecular reaction activity, magnetic field also makes the active and right of group
The affinity of metal ion increases, and more complex reactions is promoted to carry out, while magnetic field effect makes colloid electric double layer thinning, strengthens
Suction-operated, therefore, electromagnetic water treatment, which does not remove or replace in a traditional way water mineral ion, makes its softening, also not
With chemicals is added into water, it can but play the role of antiscale, kill microorganism, or even scale removal.

Specific embodiment
With reference to the accompanying drawings, a kind of electromagnetism sewage filter device of the present invention, by the magnetized area 1 and the connection that are arranged on 8 side of water inlet
Settling zone 2 two parts composition on side behind, the section rectangular in form water pipe section that the magnetized area 1 is fabricated to by non-magnetic material
It being formed with electromagnet 3,3 iron core of electromagnet is C word shapes, and C fonts open card is mounted on the correspondence two sides of rectangular water tubes section,
Electromagnetic coil 7 is set on back to the iron core column of opening;The settling zone 2 is directly connected to magnetized area, and cross-sectional width is not less than
1.5 times of magnetized area cross-sectional width, top and the left and right sides are enclosed construction, and bottom is equipped with the deflector 6 of shutter, window
Impeller meets water, and stream interface is high, and backwater stream interface is low;The lower part setting funnel-form mud storehouse 4 of deflector 6, the bottom setting row in mud storehouse 4
Dirty valve 6.
7 power supply of electromagnetic coil connects frequency converter, frequency converter output high-frequency rectangular pulse wave, output waveform periodicity
First quartile and the second quadrant are converted in ground, and the change-over period is 10-40 hours, preferably 20-30 hours.
Sewage enters magnetized area 1, the suspended matter touch opportunity in water body under the action of 3 magnetic field of electromagnet through water inlet 8
Increase, improve coalescence speed, increase flocculating rate, complicated macromolecular system is made to become simple molecular effect, improve and divide
The reaction activity of son, magnetic field also make the activity of group and the affinity of metal ion are increased, promote more complex reactions into
Row, while magnetic field effect makes colloid electric double layer thinning, enhances suction-operated, while the molecules align of water soluble colloid structure is broken
Bad, viscosity reduces, permeability enhancing, and the impurity in water body forms block-like mud, after flow sweeps along mud block to enter settling zone 2
Since section is widened suddenly, flow velocity reduces rapidly, and flow sweeps along ability to decline, and mud block is scattered in 2 bottom of settling zone, is leading
Enter mud storehouse 4 under the action of flowing plate 6, the clear water for eliminating sludge is discharged through water outlet 9, and sludge is periodically excluded through blowdown valve 5;
Mud block compactness under the action of high-frequency impulse magnetic field is strengthened, and the water content of mud further reduces, periodically
Conversion of electromagnetic iron polarity can reduce deposition of the sludge in magnetic pole.
The configuration of the present invention is simple, floor space is small, and installation is easy, and sewage treatment period is short, does not have to environment and water quality
There is particular requirement, without adding chemicals into water, can but play the role of antiscale, kill microorganism, or even scale removal, noization
Secondary pollution is learned, it is easy to spread, it can be widely applied to all types of industries waste water recycling, recirculated water scale removal and farmland
Sprinkling irrigation Water warfare and life water pretreatment.
