Description
Technical field
The present invention relates to a kind of recirculated water and peel off cleansing composition and using method thereof.
Background technology
Water resources has become the important factor of restriction petroleum chemical enterprise development, and water conservation is very urgent.Circulating water system is one and uses water rich and influential family, at present, improve cycles of concentration be recirculated water the most directly, the most effective water-saving method.But if circulating water system leaked substance, need with the displacement of a large amount of fresh waters, not only waste a large amount of fresh waters, and the consumption of water treatment agent also rolls up, cost increases substantially.
Oil leak is a kind of situation that petroleum chemical enterprise's circulating water system often occurs.Oil leak showing as in recirculated water: one be system oil-contg increase, two is that bacterial number exceeds standard greatly.Its harm have following some: one is for bacterial growth provides nutrition, makes bacterium raised growth, and the suspended substance in the bacterium of growth and recirculated water and material form biological clay, are deposited in heat-exchange equipment, affect heat transfer effect, cause corrosion; Two is that the material leaked causes sterilant to lose efficacy, material directly and chlorine and non oxidizing bactericide react, affect the effect of sterilant, thus make bacterium raised growth; Three is some material, as heavy oil spill, adheres on tube wall, cooling tower or heat-exchange equipment, impact heat transfer and cooling; Four is bacterium raised growths, has Degradation to inhibition, Scale inhibitors, thus the inhibition of influential system and scale inhibition effect.
At present, the method solving the leakage of circulating water system oil product mostly is low cycles of concentration and runs, large excretion and large complement, adds the various disadvantageous effects peeled off clean-out system reduction oil leak and bring to circulating water system and heat exchanger surface simultaneously.Low cycles of concentration operation can waste a large amount of fresh water, oily substance residual in circulating water system, and bring disadvantageous effect can to equally circulating water system and heat exchanger surface, circulating water system treatment effect can not get ensureing.
Therefore, one is applicable to oil leak circulating water system, have excellent to peel off, the stripping clean-out system of cleaning and dispersing property urgently develops.
Summary of the invention
The object of the invention is to overcome in prior art and solve the large and halfway weakness of cleaning performance of water resource waste when circulating water system oil product is revealed, and run because the method solving the leakage of circulating water system oil product in prior art mostly is low cycles of concentration, one is waste a large amount of fresh waters, two is the residual oily substance of heat exchanger surface and biological clay, burn into can be brought to conduct heat the defects such as ineffective and microbial growth, provide and a kind ofly peel off cleansing composition and using method thereof.
The invention provides a kind of stripping cleansing composition, wherein, said composition contains D-limonene, polyoxyethylene glycol and nonionic/anionic surfactant mixture, and the weight ratio of described D-limonene, described polyoxyethylene glycol and described nonionic/anionic surfactant compositions is 1:0.25 ~ 3:0.1 ~ 1.5, described nonionogenic tenside is polysorbate type nonionogenic tenside, and described anion surfactant is aliphatic alcohol polyoxyvinethene phosphate salt anionic surfactant.
Present invention also offers a kind of using method peeling off cleansing composition, this using method is: described stripping cleansing composition is added in circulating water system the blowdown after 12 ~ 48 hours that circulates, and mend with fresh water until the turbidity value of this circulating water system and add the turbidity value before described stripping cleansing composition difference between ± 10%.
According to stripping cleansing composition provided by the invention and using method thereof, on the one hand, though the present inventor finds that D-limonene is water insoluble, but can dissolve each other with arbitrary proportion with water after interpolation nonionic/anionic surfactant mixture, can be applied in thus in aqueous phase, the greasy filth of clean cycle water system heat exchanger surface, can be applicable to the circulating water system that there is oil product and reveal, and solves heat exchanger surface oil product and adheres to and the corrosion that brings and the problem such as ineffective of conducting heat; On the other hand, together with the present invention is composite with polyoxyethylene glycol by D-limonene, nonionic/anionic surfactant mixture, can be loosened the foundry loam of heat exchanger surface, and make it be taken away by current, solves the problems such as corrosion and scaling that biological clay brings to circulating water system and microbial growth.
