Abstract
The invention discloses a multifunctional synthetic water treatment agent, which belongs to the technical and formula field of central air conditioner water treatment. The multifunctional synthetic water treatment agent and a multifunctional synthetic water treatment prefilming agent are prepared from molybdate, isothiazolinone, benzotriazole, DSE-6009 butazone, dodecyldimethylbenzylammonium chloride, eugenol and the like. The multifunctional synthetic water treatment agent and the multifunctional synthetic water treatment prefilming agent can be added into water to be treated in a certain proportion for resisting scaling, corrosion and bacteria. The multifunctional synthetic water treatment agent is free from phosphorus, zinc and chromium and nontoxic, avoids side corrosion effect of oxidizing bactericide on various water system pipes, and combines high corrosion resistance, scale inhibition and sterilization.
Description
Technical field
The invention provides a kind of multi-functional synthetic water treatment agent, belong to central air-conditioning water technology prescription field, be specifically related to a kind ofly prevent that burn into dispersing and antisludging and sterilization from being the multi-functional synthetic water treatment agent of one.
Background technology
High building stands in great numbers, and world's factory all be unable to do without central air conditioning water system and these important Infrastructure of industrial cooling circulating water system.But prosperity is various wastes and a large amount of carbon emissions behind, such as: the work-ing life of Architectural Equipment and quality not only take a lot of resources, and also contaminate environment is also aggravated Greenhouse effect simultaneously.South, the arctic are quickening to melt, if or else in addition scientific development certainly will influence the human following survival and development space.The low-carbon circular economy of only advocating energy-saving and environmental protection and prolonging water system work-ing life just is the inevitable course, and efficient, healthy, continuable important foundation facility-water system just must be used the water treatment agent of environmental protection.
The efficient air-conditioning that uses is wanted dispersing and antisludging exactly, allows air-conditioner water system be in good heat exchange state, avoids energy dissipation and increases carbon emission.Sustainable use air-conditioning prevents corrosion exactly, allows the corrosion rate value in the water system be reduced to lower-most point, thereby prolongs air-conditioner water system work-ing life.The healthy air-conditioning that uses suppresses to kill bacterium in the air conditioning cooling water tower exactly, avoid the safety of harm surrounding enviroment such as air-conditioning legionella, and prevention is because the biological clay that the water system bacterium causes causes regeneration problems such as fouling, corrosion.Because the importance of central air-conditioning power consumption and Infrastructure accounts for very big proportion, and the environmentally hazardous reality of cooling tower, therefore need carry out water treatment to this.
At present, it is domestic that to be used for the medicament kind that air conditioner water handles numerous, contain " phosphorus, zinc, chromium " and be unfavorable for that the nitrite of environment and the not high prescriptions such as silicate of cost performance still adopt in a large number, part is main with organic phosphonate, but also be difficult to accomplish degradable, also be difficult to list in environment-friendly type,, also all can only solve the problem of two aspects though used the medicament of compatibilities such as poly aspartic acid, tungstate on a small quantity; Harm along with SARS in 2003, let us has brand-new understanding and demand again to the problem in the air-conditioner water system, it is exactly a large amount of air-conditioner water systems and cooling tower generation algae to system and environmental hazard, fungi, bacterium, and original traditional prescription can not the integrated multipurpose agent of the company's of accomplishing sterilization, and have obvious or potential side effect: but damage the system pipeline material as adopting oxidative bactericide to reach sterilization effect, as add the effect that silicate has inhibition, and just be difficult to remove if produce fouling, and for example tungstate may produce insoluble crystallization in dissolution process, along with the running of air-conditioner water system, pipeline in the wearing and tearing water system.
Big in the market multiple enterprises adopts Sodium Nitrite, and along with the storm sewer that is discharged into of central air conditioner system operation, the not treated rivers and lakes that directly enter can cause water pollution.Even partial drainage enters municipal sewage pipe network and treated by sheer good luck, the still difficult Sodium Nitrite of eliminating, because when sewage work is detected the sewage of handling, current procedure is not detect nitrite content (country does not make stipulations to the discharging of nitrite), though country does not make specific description to the discharging of Sodium Nitrite at " integrated wastewater discharge standard " in (GB8978-1996), but " The Prevention and Cure Law on Water Pollution of the P.C.C. " regulation, acid solution, the severe toxicity waste liquid forbids being discharged into water body, and reality is owing to there is not the technology of innovation to cause the product of these pollutions to continue to use.
