Abstract
The invention provides an efficient algae-inhibiting method for a water circulation system of a cooling tower. Silver ion-containing hydrogen peroxide is used as an algae inhibitor. When the cooling tower starts running, 3.5-4.5 g of silver ion-containing hydrogen peroxide is added in every liter of circulation water; and the silver ion-containing hydrogen peroxide is supplemented one time every 7-10 days. A stable sanitizer (the silver ion-containing hydrogen peroxide) is used as an algae inhibitor to replace conventional sanitizer, algaecide and biocide. The algae inhibitor is long in action time and obvious in effect, and can inhibit growth of the algae in the circulation water and effectively control production of biological membranes. The silver ion-containing hydrogen peroxide is colorless and has no smell, is mutually soluble with water, can be decomposed into water and oxygen, is safe and environment-friendly, is harmless to human, is not influenced by temperature and pH value, has a broad spectrum bactericidal effect, and can achieve an object of energy conservation and cost consumption.
Description
Technical field
The present invention relates to industrial circulating water system water-treatment technology field, relate to particularly a kind of method for the efficient algal control of cooling tower water circulating system.
Background technology
In cooling tower operational process, recirculating cooling water system is subject to the impact of temperature, environment, can there is bacterium and microbial film, 1. affect heat transfer efficiency, increase energy consumption: research shows, while there is the microbial film of 0.5mm on heat-exchange equipment, will increase by 20% energy consumption, if microbial film reaches 1mm on heat-exchange equipment, will make system energy consumption increase by 55%, when serious, cause cooling system cannot reach processing requirement; 2. affect the performance of water conditioner effect: the microbial film that interchanger adheres to and biological clay can make chemical treatment medicament and equipment completely cut off, and make inhibiter, Scale inhibitors not bring into play effect; 3. increase equipment corrosion: the acidic substance that the bacterium below microbial film produces in the process of metabolism can directly cause corrosion to metal, also can produce electrochemical process corrosion simultaneously; 4. the pseudomonas growing in cooling system, virus, opportunistic pathogenic agent etc. are dispersed in surrounding environment by cooling tower, can cause that people dermatitis occur and even cause dead various diseases.At present, enterprise is for removing the microbial film in circulating water system, generally in recirculated water, add traditional sterilizing and algae-removing agent (hydrogen peroxide, liquid chlorine, clorox, ozone, dioxide peroxide, quaternary ammonium salt compound etc.), but traditional disinfection sanitizer is subject to temperature, recirculated water pH impact is large, action time is short, remove algae sterilization effect general, affect taste and the smell of recirculated water, after decomposing, produce haloform, bromate, the toxic substances such as chlorite, and common hydrogen peroxide is short action time, remove algae sterilization effect limited, and the meetings such as clorox have caused serious corrosion to system, shortened the work-ing life of equipment, when microbial film is serious, cause cooling system cannot reach processing requirement, necessary stop production to overhaul, a large amount of manpower and materials have been wasted, affecting enterprise normally produces.
Summary of the invention
The invention provides the method for the efficient algal control of a kind of cooling tower water circulating system, mainly solve the problems such as existing sterilizing agent, algicide, biocide can not effectively press down removing algae, control biomembranous formation cooling tower circulating water system, and cooling tower operation energy consumption is high, equipment corrosion is serious.
Technical scheme of the present invention is achieved in that a kind of method for the efficient algal control of cooling tower water circulating system, adopt silver ion hydrogen peroxide as algae-inhibiting agent, when cooling tower brings into operation, in recirculated water, according to every liter of recirculated water, add 3.5～4.5g silver ion hydrogen peroxide, within every 7～10 days, by former addition, supplement once.
The invention has the beneficial effects as follows: the method for the efficient algal control of cooling tower water circulating system of the present invention, compared with the prior art there is outstanding substantive distinguishing features and marked improvement: 1, adopt this stable sterilizing agent of silver ion hydrogen peroxide as algae-inhibiting agent, replace traditional sterilizing agent, algicide, biocide; 2, this algae-inhibiting agent long action time and successful, can suppress the growth of algae in recirculated water, effectively control biomembranous generation; 3, silver ion hydrogen peroxide is colourless, tasteless, dissolves each other with water, is decomposed into water and oxygen, and safety and environmental protection is harmless to people; Not affected by temperature, pH value, there is broad-spectrum sterilization effect.4, silver ion hydrogen peroxide is corrosion-free to metal, the materials such as compatible stainless steel L304, L316 and high density polyethylene(HDPE), and 1% silver ion hydrogen peroxide effect 2 hours, can kill, remove the microbial film of pipe surface 99%.5, when bringing into operation, cooling tower adds algae-inhibiting agent, suppress biomembranous generation, changed and in traditional method, in recirculated water, generated go out the again method of removing algae of algae, cooling tower circulating water system microbiological contamination probability reduces greatly, increase the heat exchange efficiency of interchanger, reached energy-saving and cost-reducing object.
Fruit juice implementation result (cooling tower operation is index after 30 days)
