Abstract
The invention discloses a sludge stripping aid of a circulating cooling water system. The aid is prepared from the following raw materials in percentage by weight: 8 to 12 percent of sodium dodecyl benzene sulfonate, 4 to 6 percent of triethanolamine, 4 to 6 percent of polydimethylsiloxane, 12 to 18 percent of sodium polyacrylate and the balance of pure water, wherein the sludge stripping aid is used together with a strong oxidant to remove the sludge from the cooling circulating water system, so that the using amount of strong oxidant can be reduced by 40 to 60 percent compared with that of the strong oxidant which is used singly, the sludge can be slowly stripped in the form of small blocks and has high dispersibility in water and a little of foam, the sludge cleaning time is prolonged, the cleaning efficiency reaches over 99 percent, the aid has low corrosion to pipes of the cooling circulating water system, the service life of the cooling circulating water system is prolonged, phenomena such as blockage and the like are avoided, and safe operation of the cooling circulating water system is guaranteed; and thus, the aid has the advantages of reducing the amount of the used strong oxidant, reducing the corrosion of the strong oxidant to the metal pipe, prolonging the effective time of the sludge stripping and improving the cleaning rate.
Description
Technical field
The present invention relates to the mud stripper of circulating water system, the mud that is specifically related to a kind of recirculating cooling water system is peeled off auxiliary agent.
Background technology
In the recirculating cooling water system, water temperature is suitable, grows a large amount of bacteriums, microorganism and algae easily, as in sun-drenched places such as cooling towers, grows easily as various algae such as moss, moss; The insufficient place of dissolved oxygen in pipeline grows easily as anaerobism mushrooms such as sulfate radical reduction bacterium, siderophilic bacterias; These biologies are that main body bonds together and just formed biological mud with the colloidal suspended substance in the water, cover internal surfaces such as the condenser of recirculating cooling water system and pipeline, biological mud has hindered normally passing through of water coolant, reduced the cooling performance of condenser, the difference current potential that biological mud forms also can cause inside corrosions such as condenser and pipeline to be accelerated.Therefore add the mud stripper in the recirculating cooling water system of being everlasting removes biological mud, the mud stripper of recirculating cooling water system comprises strong oxidizer and biocide etc. at present, strong oxidizer such as hydrogen peroxide and clorox commonly used, in the recirculating cooling water system, 13%(weight) chlorine bleach liquor's consumption is about the 5000mg/L(water coolant), mud is peeled off to lack working lipe and is about 5 hours, mud is suspended in mud sedimentation again after 5 hours in the water coolant, therefore need draining-off sewage in 5 hours, prevent mud sedimentation once more, clean rate is about 80%, and the water coolant turbidity only rises about 6 times during desilting.35%(weight) consumption of hydrogen peroxide is about 5000mg/L, mud is peeled off and is about 12 hours working lipe, mud is suspended in mud sedimentation again after 12 hours in the water coolant, therefore need draining-off sewage in 12 hours, prevent mud sedimentation once more, clean rate is about 90%, and the water coolant turbidity rises about 10 times during desilting.Single at present with 13% chlorine bleach liquor or 35% hydrogen peroxide, the desilting time is shorter, clean rate is lower, the strong oxidizer large usage quantity, the strong oxidizer of high density is also big to the metallic conduit corrosion of recirculating cooling water system, and the mud piece of peeling off is also big, and the mud of bulk may stop up filtering net and interchanger, can cause great production safety accidents such as parking in the cleaning process of not stopping.
Summary of the invention
Technical problem to be solved by this invention provides a kind of mud of recirculating cooling water system and peels off auxiliary agent, this mud peels off auxiliary agent and strong oxidizer is used, have reduction strong oxidizer consumption, reduce the corrosion of strong oxidizer, prolong mud working lipe of peeling off and the advantage that improves clean rate metallic conduit.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of mud of recirculating cooling water system is peeled off auxiliary agent, preparation of raw material by following weight percentage component forms: Sodium dodecylbenzene sulfonate 8-12%, trolamine 4-6%, Dimethicone 4-6%, sodium polyacrylate 12-18%, surplus is a pure water.Sodium dodecylbenzene sulfonate is an anion surfactant, and significant soil removability and degreasing power are arranged, and has synergy with strong oxidizer, can allow mud peel off better, improves the rate of cleaning; Trolamine is highly effective chelating agent and inhibiter, can reduce the corrosive nature of strong oxidizer to metallic conduit, the metallic conduit of protection recirculating cooling water system; Dimethicone is a defoamer, and foamy produces in the time of can suppressing mud and peel off, and prevents that foam from causing the liquid level virtual height and causing system to be stopped because of lack of water; Sodium polyacrylate is a dispersion agent, can disperse the suspended matter in the water coolant, makes suspended substance be difficult for precipitation, prolongs the desilting time.
The weight percent component of described raw material is: Sodium dodecylbenzene sulfonate 10%, and trolamine 5%, Dimethicone 5%, sodium polyacrylate 15%, surplus is a pure water.
Compound method: the percentage component takes by weighing Sodium dodecylbenzene sulfonate, trolamine, Dimethicone, sodium polyacrylate by weight, and uniform mixing adds component amount pure water, stirring and dissolving.
Using method: the water coolant water level with recirculating cooling water system before using remains on most significant digit, peel off auxiliary agent according to adding 400-500mg mud of the present invention in every liter of water coolant, allow auxiliary agent circulation primary in water system, in every liter of water coolant, add the 2000-3000mg strong oxidizer again, detected the primary water turbidity every 30 minutes, when turbidity reaches peak value, rise approximately 15-20 doubly after, water is changed in beginning in a large number, be about 20-23h the working lipe that mud is peeled off, so in 20-23h the suspended substance in the water is discharged.Adopt the strong oxidizer and auxiliary agent of the present invention collocation use of low concentration, mud is slowly peeled off, piece is little, and in water good dispersity, situation such as avoid clogging, the safe operation of safeguards system.
Compared with prior art, the mud that the invention has the advantages that a kind of recirculating cooling water system is peeled off auxiliary agent, preparation of raw material by following weight percentage component forms: Sodium dodecylbenzene sulfonate 8-12%, trolamine 4-6%, Dimethicone 4-6%, sodium polyacrylate 12-18%, surplus is a pure water; This mud is peeled off auxiliary agent and is cooperated the mud of removing in the recirculating cooling water system with strong oxidizer, can reduce the strong oxidizer consumption, than single with the strong oxidizer 40%-60% that descended, mud is slowly peeled off, piece is little, and in water coolant good dispersity, foam is few, the desilting time obtains prolonging, clean rate reaches more than 99%, and is few to the corrosive pipeline of recirculating cooling water system, and recirculating cooling water system prolongs work-ing life, and situation such as avoid clogging, ensure the safe operation of recirculating cooling water system.Therefore the present invention has and can reduce the strong oxidizer consumption, reduces the corrosion of strong oxidizer to metallic conduit, prolongs working lipe that mud peels off and the advantage that improves the rate of cleaning.
