Description
Technical field
The present invention relates to Heat Exchanger Fouling performance monitoring and diagnostic field, and in particular to a kind of super with anti-fouling performance
The preparation of hydrophilic micro-nano copper oxide film and detection method.
Background technology
Tube-type down-flow evaporator has the advantages that simple in structure, heat transfer efficiency is high, cost of investment is low, discharge concentration is high, especially
It uses the tube-type down-flow evaporator of the copper pipe with preferable heat-transfer effect at chemical industry, papermaking, food, sea water desalination, waste liquid
It is used widely in the fields such as reason.
Usually in the course of work of copper pipe type falling film evaporator, whether the evaporation process containing alundum (Al2O3) black liquor can
Safely, effectively, the generation stablized, it is necessary to be provided simultaneously with that falling liquid film is density stabilized and thermic load stablizes two primary conditions.Falling liquid film is close
Degree is the girth fluid flow per second flowed through in unit tube, black containing alundum (Al2O3) if the flow is less than certain value
The liquid film of liquid will rupture.Black liquor will be converted into wadding strip stream in the membranaceous stream of pipe internal surface, then will certainly in pipe
The thinning of liquid film in some regions.If these liquid film thinner region surfaces are inadequate to the affinity of water, i.e., it is existing that " main pipe " can occur
As.The generation of main pipe can not only make copper pipe type falling film evaporator evaporation efficiency reduce and also with stoste enter copper pipe type falling liquid film steaming
It is concentrated by evaporation in hair device, the precipitation of crystallization, crystallization is attached to evaporation inside pipe wall and forms serious scale, so as to reduce copper pipe type drop
The operation stability of film evaporator.
Chinese invention patent publication number CN101805908A discloses that " a kind of in steel substrate surface to prepare titanium dioxide anti-corrosion anti-
The method of dirty film ", it is resistance to that this method using sol-gal process in tube-type down-flow evaporator evaporation tube steel substrate surface prepares titanium dioxide
Corrode anti-tartar film, but uneven film thickness is even made from this method, and film plasticity is poor, easy brittle failure and cracked, leads
Cause anti-tartar disabler and bring serious chemical attack.Chinese invention patent Publication No. CN102154672A discloses " tool
Have non-metallic film of high heat conduction efficiency and antifouling capability and preparation method thereof ", this method uses laser ablation and collosol and gel
One layer of nonmetal film is made in metal or metal alloy heat exchanger surface in the method being combined, but this kind of method prepares non-gold
It is complicated to belong to thin-film technique, cost of manufacture is higher, is unfavorable for industrial application.Chinese invention patent publication number
CN104830124A is disclosed " a kind of preparation method of stripe anti-tartar coating ", and this method uses mask and light polymerization technique phase
With reference to method be prepared for a kind of stripe antibiont dirt function coating material, but the only pin of coating material made from this method
To effective, the effect unobvious for other dirts such as particulate fouling and crystallisation fouling of biofouling.
Copper pipe type falling liquid film device operation in, how by varying copper pipe type falling liquid film device evaporation tube inner wall surface anti-tartar
Can, avoid and prevent " main pipe " and fouling, be technical barrier urgently to be resolved hurrily at present.And the surface resistive connection that existing literature is introduced
The method of dirty ability, it is impossible to which thoroughly prevention copper pipe type falling film evaporator evaporation tube inner wall surface fouling, is also unfavorable for realizing industry
Change and promote and apply.
The content of the invention
For this reason, for can not effectively solve asking for the copper pipe type falling film evaporator easy fouling of evaporation tube inner wall surface at present
Topic, the object of the present invention is to propose preparation and the detection side of a kind of super hydrophilic micro-nano copper oxide film with anti-fouling performance
Method, since the micro/nano film of preparation has super hydrophilicity, can make falling film evaporator evaporation tube inner wall surface play ant-scaling
Effect, and then improve falling film evaporator evaporation efficiency and operation stability.

Face aoxidizes out one layer of Kocide SD, then being heated makes its dehydration form cupric oxide, and cupric oxide forming core and long general orientation are and hydrogen
Cupric oxide is consistent, cupric oxide formation cluster-shaped, and there are many micropores, moisture film again between different cupric oxide to flow through with these
Siphonic effect can be formed during the surface of micropore, water absorption is prevented the forming core of dirt on surface；
2. since cupric oxide super-hydrophilic film surface is larger to the tension force of water, water base can sprawl completely on its surface
Open, i.e., flowed down so that stablizing film-like from evaporation pipe internal surface after black liquor film forming, so as to avoid the generation of main pipe.Main pipe lures again
The internal factor of fouling is sent out, i.e. main pipe can produce dry and wet junctional area, and dry and wet junctional area can be there are the huge temperature difference so that dirt
Solubility is reduced and a large amount of forming core and grown up；
3. super-hydrophilic film can effectively adsorb water, water membrane is produced on its surface, which can prevent dirt from existing
Forming core on its surface, another aspect vapor in forming core, grow up, escape out contact surface during, to being attached to hydrophilic film table
The dirt in face can play the role of washing away.
A kind of preparation of super hydrophilic micro-nano copper oxide film with anti-fouling performance of the present invention and detection method, this is micro-
Nano thin-film not only enables copper pipe type falling film evaporator evaporation tube have scaling property, but also the water vapour to be evaporated provides
More forming core places so that vapor forming core efficiency and evaporation efficiency increase, and greatly improve copper pipe type falling film evaporator
Evaporate the anti-fouling performance of inside pipe wall and the stability of operation.Copper pipe type falling film evaporator evaporation tube inner wall surface provided by the invention
Anti-tartar method is not only simple, but also manufacture is of low cost, beneficial to industrialization and business promotion.
