Said method and device design achieve the purpose of the present invention.
The inventive method can utilize the affine adsorption effect between object to remove ultraviolet generator surface chelate knotDirt, it is ensured that the permanently effective work of ultraviolet generator, its device has simple in construction, low cost, removes and preventsThe advantage that dirt efficiency is high and using effect is good.
The present invention proves safely and effectively through actual tests.Research shows:
One, foulant (chelate) origin cause of formation on ultraviolet generator surface.
1, environmental protection equipment normally used ultraviolet generator mostly is quartz glass tube and makes.Quartz glass is dioxySiClx one-component, hardness greatly up to Mohs seven grades, have wear-resistant, high temperature resistant, the coefficient of expansion is low, resistance toThermal shock resistance, chemical stability and electrical insulation capability are good, and can pass through ultraviolet and infrared ray.Quartz glassSurface has the convex-concave form on microcosmic, easily attaches the float assembled in fluid and precipitate.
2, the material chelate of ultraviolet generator surface scale.Gasolene ingredient is hundreds of kind of Organic substance mixing,Wherein partial organic substances, the chain hydrocarbon of some band metal ions is easy to after photodissociation mineralising decompose made by chelatingWith generating chelate.Chelate is to be had circulus by what central ion and multidentate ligand were combined intoCoordination compound.Chelate is to cooperate with the one of thing, in the structure of chelate, necessarily has one or more multiple toothPart provides multipair electronics to form coordinate bond with centrosome.There is the coordination compound of circulus, be by twoOr multiple ligand forms the chelation of chelate ring with same metal ion and obtains.There is circulusCoordination compound, by the chemical reaction-chela having two or more ligand and same metal ion and being formed chelate ringCooperation with and obtain.The rule that metal ion forms chelate with part is hsab theory, it is simply that:Hard parent is hard, and soft parent is soft.The chelate that metal ion generates with multidentate ligand, generates than it and monodentate ligandSimilar coordination compound has higher stability.
3, fouling mechanisms is material " affine " effect." affine " this word has wide significance,And for defining more than 100 year.Mutual by electrostatic interaction for simple compound such as Na and ClThe phenomenon attracted is i.e. a kind of affinity interaction, and therefore affinity interaction is the phenomenon that nature generally exists.ThisPhenomenon is very exclusiveness, specific combination, or referred to as specificity interacts, and its active force is claimedFor " affinity ", " affinity " is also named the interaction that affinity interaction is the complexity of two intermolecular existence.
Therefore, the radiant light of ultraviolet generator is when irradiating through surface quartz glass, near quartz glass tableThe chain hydrocarbon of the band metal ion in face is easier to after photodissociation mineralising decompose generate chelate, the surface of quartz glassConcavo-convex characteristic produces delay effect to these chelates, forms scaling fouling.
The present invention utilizes the adsorption function that sheet metal is affine, it may be assumed that chelate is electronics can be total to metal ionBody, the coordination compound that atom combines with coordinate bond, therefore the metal for cation has more intensive affinity；Utilize that the microcosmic upper surface of quartz glass is concavo-convex is susceptible to more greatly friction phenomenon and glass hard (HRC65Yi Shang) can have greatly resistance toAbrasion, high temperature resistant, the coefficient of expansion is low, resistance to heat shocks, chemical stability and the good characteristic of electrical insulation capability,Allow sheet metal carry out friction on its surface and generate electrostatic, produce the metal surface of positively charged.Due to quartz glassThe affinity adsorbing chela and thing is the atom Coulomb force of lattice, and the electrostatic affinity of sheet metal is far longer thanThe Coulomb force of atom, adds the chelate more intensive demand to positive metal ions coordinate bond, so when thisAfter friction generation electrostatic, chelate is by the strong affine absorption of sheet metal, and Quartz glass surfaces there's almost no chelatingThing, meanwhile, relative motion also removes other attachments of ultraviolet generator, the light transmission efficiency of quartz glassBeing sufficiently maintained, test shows up to more than 85 percent.
Detailed description of the invention
As it is shown in figure 1, a kind of method utilizing affine adsorption removal ultraviolet generator surface chelate fouling, bagInclude following steps:
