Reaction mechanism：When fluid flows through the present invention, 65 μ A or so steady-state current can be formed therebetween.This electricity
The solvent molecule made in solution is produced polarity effect by the continuous action of stream, forms the dipole of solvent analysis.The dipole of polarization
It is sub to be rearranged with electrically charged incrustation ion, new incrustation ion couplings are formed, are distributed in suspended state in solution system,
It reduce further into the possibility of dirt reaction.Dirty salt can be substantially reduced simultaneously because of wall deposition effect caused by charge adsorption
Should, reduce deposition of the calcium and magnesium dirt in pipeline wall.
The crystal habit of the insoluble molecule such as calcium carbonate, magnesium carbonate can also change under the function of current.Calcium carbonate, carbon
Sour magnesium molecule typically has two kinds of crystal habits：One kind is " marble type " structure, and quality is hard, and adsorptivity is strong, total molecular weight compared with
Greatly, it is the common form of calcium and magnesium dirt under normal condition.Another kind is " aragonitic " structure, and quality is soft, and adsorptivity is not strong, total score
Son amount is smaller.Typically formed under weak electric field continuous action.Due to that in complete intelligent antiscaling, descaling alloy and can flow at work
Weak electric field is formed between body, therefore the formation of " aragonitic " dirty salt can be promoted, while makes existing dirty salt that " marble type " occur
Transformation of the structure to " aragonitic " structure, make the hardened dirty layer gradually soft purpose for coming off, reaching pipe-line system scale removal.
With coming off for dirty layer, tube wall metal surface is gradually exposed.Dipole after polarization will be sent out with bare metallic surface
Raw wall effect, makes tube wall metal surface deposit certain thickness incrustation ion couplings (about 500 μm of thickness).This layer of couplings
Tube wall metal and fluid system are separated, serve the effect of tube wall corrosion-resistant to a certain extent.Because couplings deposition is logical
It is different from the deposition growing Principle of Process of common dirty layer caused by the Electrostatic Absorption for crossing dipole and wall metal, therefore, coupling
The thickness of thing sedimentary does not change over time, and only relevant with the flow velocity of pipe-line system.
The present invention it under the premise of fluid chemistry composition is not changed, using advanced light current composite scale mechanism, prevent knot
The generation of dirt, and there is very strong dissolution of scale ability.Running does not need additional maintenance, and no magnetic is without electricity, it is not necessary to additional
Power supply.When containing excessive free electron in fluid, the electric charge of scaling cations is neutralized by free electron, it is difficult to and acid
Root knot synthesis dirt.The presence of excessive free electron adds the ion concentration of fluid, and saturation index declines, CO2Partial pressure rises, and makes
The solubility increase of dirty salt is obtained, produces certain molten dirty effect.Meanwhile the continuous action of weak electric field can cause dirty salt crystal to occur
" calcite type " changes to " aragonitic ", and dirty salt crystal becomes loose, is reduced with wall adhesion, causes hardened dirty layer
Gradually release dissolving.
Beneficial effect：The antiscale chip architecture of the present invention uses vane type antiscale piece, in use, fluid enters via pipe joint
Inside antiscale pipe, the increase of vane type antiscale piece and the contact area of fluid, the influence to flow velocity and the influence of pressure difference can be reduced,
The impeller blade of even arrangement is easy to process, and distributing equilibrium, is advantageous to the turbulent flow effect of current, flows through the antiscale in antiscale pipe
During piece surface can fast automatic formation stabling current, by light current effect neutralize into dirty metal ion positive charge, effectively
The formation of dirt is controlled, while the continuous action of weak electric field can make hardened dirty block gradually dissolve, come off, and realize scale inhibition, remove
Dirt.Fluid after the processing of antiscale piece continues to move, and is discharged via outlet.The present invention is less using material, and can effectively increase
With the contact area of fluid, cost can be but reduced while improving antiscale efficiency, in big pipeline footpath, pipeline complex environment
Disposal ability is stronger, and antiscaling effect becomes apparent from.The present invention is simple in construction, using the complete intelligent antiscaling, descaling of more rational formula component
Alloy, it is nontoxic element, while further improves descaling and antiscaling performance, and the complete intelligent antiscaling, descaling alloy of the present invention is
Along the column crystal alloy of S110 crystallographic axis oriented growths.Compared with the post alloy that the S100 crystallographic axis of prior art is formed, S110
The post alloy structure that crystallographic axis is formed is more advanced, more stable, and the alloy that is formed release steady-state current is due to the optimization of structure, surely
State electric current burst size is improved；Electric current more tends towards stability, and not easily runs off electronics.The alloy compositions that i.e. S110 crystallographic axis obtains
Electronegativity is coordinated relation and electric current sustained release performance is substantially strengthened.Experiment shows, the complete intelligent antiscale that the present invention uses
Scale removal alloy activation electric current improves about 60% than the scale prevention device of existing copper-base catalyst alloy, composition more reasonable benefit/risk, adds
Work cost is also lower.

Based on industrial using, waterpipe and circulating water pipeline caliber are bigger, and pipeline is more complicated, it is often necessary to
Scale-proof apparatus is installed on total pipeline and large diameter pipeline, but due at the orifice-plate type of pipeline installation requirement and the horizontal product of industry
The deficiency of reason ability, antiscale chip architecture of the invention uses vane type antiscale piece 21, in use, fluid enters via pipe joint 3
Inside antiscale pipe 1, the increase of vane type antiscale piece 21 and the contact area of fluid, the influence to flow velocity and the shadow of pressure difference can be reduced
Ring, evenly distributed impeller blade 213 is easy to process, and distributing equilibrium, is advantageous to the turbulent flow effect of current, flows through antiscale pipe
During antiscale piece surface in 1 can fast automatic formation stabling current, neutralized by the effect of light current into dirty metal ion just
The formation of electric charge, effectively control dirt, while the continuous action of weak electric field can make hardened dirty block gradually dissolve, come off, it is real
Existing scale inhibition, scale removal.Fluid after the processing of antiscale piece continues to move, and is discharged via outlet.The present invention is less using material, and energy
Effectively increase and the contact area of fluid, cost, pipeline bigger in pipe diameter can be but reduced while improving antiscale efficiency
Disposal ability is stronger in more complicated environment, antiscale is safer, more stable, steady-state current burst size is higher, electric current is persistently released
It is stronger to put performance.
