Background technique
Container was burnt repeatedly after the meeting, was precipitated due to the evaporation of water in water containing being slightly soluble in the calcium sulfate (CaSO4) of water, former
The calcium bicarbonate (Ca (HCO3) 2) and magnesium bicarbonate (Mg (HCO3) 2) first dissolved, is decomposed in the water of boiling, releases titanium dioxide
Carbon (CO2), generates insoluble calcium carbonate (CaCO3) and magnesium hydroxide (Mg (OH) 2) also precipitates, and can also generate sometimes
MgCO3.Material is thus formed scales.Scale can block pipeline, cause booster etc., in addition the complicated component of scale, be easy aggregation
The impurity such as heavy metal, to cause water pollution once again.
Scale is broadly divided into hard scale and dirty two kinds soft according to the difference of its Crack cause and shaped state.When containing in water
When the impurity such as carbonate colloid, bacterium and organic matter, carbonate is similar to the sandstone in cement mortar, and colloid, bacterium and has
Machine object etc. is then equivalent to the cement in cement mortar, when the stickums such as water-borne glue body, bacterium and organic matter and carbonate are common
Effect, then forms the hard scale being adhered to each other with container (or pipe surface) under the conditions of high-temperature boiling.Once and colloid, thin
After the stickums such as bacterium and organic matter are removed and (are such as filtered out by ultrafiltration), even if calcium and magnesium ion and carbanion are dense in water
Degree is very high, the pure white and loose soft dirt of the carbonate easily removed is also carried out into, without generating hard scale.
There is visible rust tumor to be formed in the pipeline for red water occur, this is the production that a kind of iron bacteria of danger is corrosion process
Object, it hinders the bactericidal effect of chlorine residue, protects the growth of microorganism under iron dirt.When encountering siphon pressure and change in flow
When, microorganism scurries into water at once, becomes very big hidden danger.
Based on this, the prior art has carried out a large amount of antisludging agents and antiscaling device.Such as patent of invention CN201320107813.1
Disclose a kind of Si-P crystal purifier, it is desirable to provide it is a kind of easy to use, hard water can be effectively purified, the silicon for preventing scale from generating
Phosphorus crystalline substance purifier.Patent of invention 201110190315.3 discloses a kind of Si-P crystal answering as drop fluorine material in water process
With.Patent of invention 201620462957.2 discloses a kind of soft water scale removal composite filter element, including shell, filter core main body and Si-P crystal
Tank.Patent of invention 201811654313.3 discloses a kind of scale inhibition pipe, pours into FOF antisludging agent in the middle layer of filter core, reach compared with
Good scale inhibition effect, and can constantly play the role of scale inhibition.Meanwhile FOF antisludging agent enter water after will not change water quality, to original
Water pH influence is small, is conducive to the characteristic for keeping raw water.It is deep that patent of invention 201210315848.4 discloses a kind of condensed oil sewage
Softening method is spent, by carrying out preliminarily softened processing, then the absorption by being filled with chelating resin using Macroporous Weakly-Acid
Tower or adsorption column carry out adsorption treatment, it is made to still ensure that be back to thermal recovery boiler and do not generate fouling after saving except system on silicon and ask
Topic.Patent of invention 200810196877.7 discloses a kind of method of recirculated cooling water ion exchange softening micro-basification processing, leads to
Na type cation exchange resin is crossed to remove Ca2+ and Mg2+ ion in water removal and be exchanged for Na+ ion；Then by Na type sun from
Sub-exchange resin treated water removes in water removal strong acid anion simultaneously by OH type, CO3 type or HCO3 type anion exchange resin
It is exchanged for OH-, CO32- or HCO3- anion；Various preservatives, corrosion inhibiter, antisludging agent, water stabilization are used exempting
Under the conditions of the additional chemical agent such as agent and Biocidal algae-killing agent, with anticorrosion, good antiscale property, preventing microorganism breed technical effect and
Substantially reduce the overall economic efficiency of concentrated water and chemical substance discharge.Patent of invention 201610840566.4 discloses a kind of application
In the antisludging agent of industrial cooling circulating water system, which is the aqueous solution of sheet graphene oxide；By graphene oxide antisludging agent
Be added in industrial circulating cooling water, when incrustation ion concentration is larger in cooling water, there is scale formation when, graphene oxide can
To be coated on into dirty particle (such as calcium carbonate) surface, and change calcium carbonate etc. into the crystal type of dirt matter, form cotton-shaped soft dirt,
To make calcium carbonate etc. in water be not easy to be adhered to the metal surface of heat-exchange apparatus at dirt matter, and with the row of cooling water system
It is dirty and remove, reach scale inhibition purpose.
There are the longevity when however, existing antisludging agent Si-P crystal, FOF, chelating resin, ion exchange resin are for water purification scale inhibition
Order the problems such as short, at high cost, replacement is cumbersome.And using sheet graphene oxide, directly as antisludging agent, there are scale inhibition effects not to show
Work problem.
