In optimal technical scheme as above-mentioned sweep-out method, the addition quality and the matter of conduction oil of process water in step S2
Amount is than being (0.9~1.1):1.
Beneficial effects of the present invention are：
1st, compared to the prior art, conduction oil carbon remover of the invention and sweep-out method, use base water for solvent,
Carbon remover is the aqueous solution.
Flocculation can be played a part of to the carbon distribution in conduction oil using nonionic surfactant, addition it is a small amount of it is non-from
Sub- surfactant can fully flocculate the carbon distribution in conduction oil, and flocculating effect reaches more than 99%, and addition is 0.005~
5ppm.Flocculation is not only played a part of to the carbon distribution in conduction oil using anion surfactant, and carbon distribution can be promoted
The effect of sedimentation, mixes compounding use with anion surfactant by nonionic surfactant and produces synergy, can
The effect of flocculation carbon well, and rapid subsidence are played, contributes to complexing agent that carbon distribution is fully erased, to improve clean effect.
Can be in oil using anionic surfactant and the two kinds of surfactant of nonionic surfactant
Dirty surface is adsorbed, and makes its wetting, expansion, and then row actively penetrates into grease gap, makes greasy dirt thing in organic washing agent group
Micella is gradually crispaturaed into the presence of compound, through the continuous circulation scouring of pump so that grease progressively disengages tube wall.
Although the calcium salt that anion surfactant is generated in base water is not readily dissolved in water, can only be dispersed in water makes it
Washability reduction, but be due to that complexing agent is with the addition of in carbon remover, anion surfactant is compounded with complexing agent, will
Calcium, magnesium ion complexing, it is possible to used in base water without influenceing its clean result.Moreover, the complexing agent energy used
Enough play a part of decarbonizing, keep cleaning.
2nd, scale removal is carried out to conduction oil using above-mentioned carbon remover, carbon remover, process water is added in conduction oil and mixed
Stir, and carry out circulating-heating, clean tube wall coking grease using compatibility principle, realize to the carbon distribution in conduction oil
Remove, elimination efficiency reaches more than 98%, reduces influence of the carbon distribution to conduction oil performance, extend service life of heat transfer oil
It is long, operating cost is reduced, heat utilization rate is high.Moreover, making coking grease degrade, it is to avoid conduction oil is chronically at hot environment
Under, and going bad, being carbonized and coking phenomenon for producing, the normal operation of system is not influenceed, and dirt plugging phenomenon does not occur.
3rd, carbon remover can make oily matter gradually crispatura into micella under the effect of complex cleaning and washing agent composition, constantly emulsification,
Through continuous circulation scouring, the oily matter of dispersion and emulsion is departed from heating surface, into heat-conducting oil system, participate in heat conductive circulation, into
For the component of conduction oil.
4th, the cleaning agent does not have any spot corrosion, oxidation or other harmful reactions to equipment, cleans after terminating in equipment
Metal surface forms layer protecting film, with certain anti-rust action.
5th, fire and the explosion accident produced by heat-conducting oil system equipment wall by coking hot-spot is avoided.
