Description
Technical field
The present invention relates to a kind of descaler, relate in particular to a kind of for preventing button type automatic intelligent descaler and the descaling method of Types of Heat Transmitter in Wall Mounted Boilers fouling and ground heating system geothermal tube encrustation, thereby improve the thermal efficiency of wall-hung boiler and the heating quality of floor heating.
Background technology
Along with updating of heating system, geothermal heating system is generally adopted in China northeast, North China and the Northwest, but the scale problems of geothermal heating system affects resident's heating quality always.The way adopting at present only has mechanical cleaning, and conventional mechanical cleaning has high-voltage pulse ablution and high pressure projectile ablution.Facts have proved, no matter adopt that mechanical cleaning method, all can only dispose the foreign material that are attached to incrustation scale surface.As biological mud, impurity, colloid admixture etc.Because incrustation scale is in fact a kind of lime stone crystallization, hardness is higher, adopts any mechanical system all cannot be washed.Really effectively prevent fouling, can only adopt the method for " controlling stomach trouble ", from scale inhibition, antiscale is started with, and finally could effectively reach non-scaling this purpose.
The formation of incrustation scale is a complicated physical and chemical process, and it must possess two conditions.One, must contain the mineral salt after dissolving in water, wherein taking calcium bicarbonate and magnesium bicarbonate as main component, and these mineral salts arch-criminal of fouling just, and pure water is non flouling behaviour; Its two, water must heat.Heating water has just in time met above-mentioned two conditions, and therefore fouling is inevitable phenomenon.The thermal conductivity factor of incrustation scale is extremely low, once underground heat radiating tube inwall forms dirt layer, the hot water in radiating tube cannot effectively by dissipation of heat out, therefore will reduce heating quality greatly.
Unless employing chemical method, otherwise calcium carbonate and magnesium carbonate in floor heating water system cannot be removed.But more harm than good for chemical method, its operating cost is higher on the one hand, and main is serious environment pollution, and old friends seldom adopt.Therefore still there is fouling hidden danger in geothermal system.Electrochemical theory is told us, when calcium, magnesium ion are that incrustation ion is under certain magnetic induction intensity and electric-field intensity, its ionic crystal type can produce change, and radical change can occur the crystal structure of incrustation ion, makes easily to become dirty crystal to become and is difficult for into dirty crystal.But have individual prerequisite, the alternating electromagnetism field frequencies range applying must be identical with the eigentone of incrustation ion crystal, reach resonance object to meet incrustation ion crystal.
Because the incrustation ion in water is not of uniform size, their particle geometric volume differs tens times of even hundreds of times, therefore its eigentone also differs greatly.Reach and the resonance of all incrustation ions, it is wide that this just requires that the frequency coverage of alternating electromagnetic field must be suitable.Adopt common frequency sweep and frequency changer circuit to be difficult to reach.
Heating water is substantially all macromolecular mass water, and so-called macromolecular mass water refers to that composition hydrone is not single hydrone (being made up of H2O), but numerous single hydrone is associated and formed bulky grain water clusters by hydrogen bond or oxygen key.The dissolving power extreme difference of macromolecular mass water, the mineral salt dissolving in water is easy to reach supersaturation and separates out, and accelerates the formation of incrustation scale.As long as macromolecular mass water is managed to become single hydrone, and can not reach lysate supersaturation and separate out formation incrustation scale.Known by electrochemical theory, macromolecular mass water and incrustation ion have identical characteristic, when macromolecular mass water adds under electromagnetic field effect outside, as long as the alternating electromagnetism field frequencies range applying is identical with the eigentone of macromolecular mass water, just producing resonance, macromolecular mass water fragments into the single hydrone of enormous amount.The granular size of large molecule water body differs greatly, by formed by tens single hydrones, by may be formed by more than 6,000 single hydrones.
Can find by Chinese patent CN201056505Y " a kind of intelligent-induction water treatment facilities " and Chinese patent CN102359748A " Intelligent geothermal cleaning-free descaler ", this two schemes all has weak point.As previously mentioned, in water, the geometric volume of incrustation ion differs greatly, and the particle of macromolecular mass water also differs greatly, and the alternating electromagnetism field frequencies range that therefore requires main frame to produce must have very wide coverage.CN201056505Y utilizes cpu to control respectively two groups of oscillators, i.e. " A oscillator " and " B oscillator " after two groups of signals amplify respectively, is added on inductance coil simultaneously, and two groups of signals combine on helix.And CN102359748A utilizes cpu to control respectively " digital frequency conversion circuit " and " swept-frequency signal generator circuit ", the signal of above-mentioned two circuit outputs adds to " frequency synthesizer " simultaneously and carries out frequency synthesis, and the frequency synthesis after amplifying is added on helix tube inductor again.Facts have proved, utilize frequency combining method can not obtain very wide frequency coverage, therefore must look for another way.
The inductor of current electronic cleaner is on the market all a pipe joint section, and winding around on pipeline section forms a joint particular electrical sensor.This inductor needs the water inlet pipe before water knockout drum to cut off when mounted, then by inductor pipeline section serial connection fusion water inlet pipe, when installation, need in pipe, under anhydrous condition, carry out, therefore very trouble of construction, and it is two ellipses that wound form coil produces the magnetic line of force, antiscale like this, scale inhibition effect are bad.
