Chemical Substance Treatment Regarding Circulation
Cooling Water pertaining to water thoroughly cleanFinally
, the cooling water could be recycled. Open-loop cooling tower method can also be referred to as the cooling tower system, which has been extensively utilized in the factory.With the fast development of business, the issue of industrial
cooling water treatment more and more leads to social problem. As we all know, there are many various treating ways, which is often physical, physical chemistry, chemical, and so on., but only the chemical method is increasingly broadly used, since the chemical therapy, by comparison, is simple, and the mixed impact of it can be much more satisfactory. Via increasing the concentration of circulation water, the consumption of chemical substances can be significantly decreased, and also the price can also be greatly decreased. As per the chemical treatment method, chemical substances shall be added during the process to be able to stop scaling, corrosion and biological silt in the cooling water therapy system. And also the frequently used chemical substances are corrosion inhibitors, scale inhibitors and biocides, etc.
There are two kinds of circulation cooling h2o therapy system: closed-loopcooling
water therapy system and open-loop cooling water method. In the closed-loop water method, water isn't exposed within the air, and it's cooled by cooling medium via the heat transfer gear. By this method, h2o loss is rather little for it nearly doesn't focus, and also the classic representative of this method will be the inner combustion motor cooling water method. In the open-loop water method,cooling h2o modifications into hot h2o through heat exchangers by raising the temperature. The hot water aerates and contacts the air through the cooling tower, and also the water temperature then is reduced because of to evaporation cooling and contact cooling. Finally, the cooling h2o would be recycled. Open-loop cooling tower method is also referred to as the cooling tower method, which continues to be commonly utilized in the factory.
Regarding the maintenance of circulation cooling h2o system, cleaning and pre-filming are known as the pretreatment of the chemical treatment. During the entire process of gear and pipes set up, debris, sundries, and dirt will inevitably be left within the method, and sometimes the corrosion and oil contamination of cooling gear can also be quite severe. If these fragments and oil contamination is not cleared up, the next step of prefilming will probably be greatly impacted. Meanwhile, grime, slime and metal corrosion also exists in the previous cooling gear system, which will critically impact the effectiveness of equipment and warmth transfer if not cleaned. Consequently, the cleansing work is important to generate around the circulation cooling water system. In terms of the the prefilming, a lot corrosion inhibitor is cast during the early period of method driving, and its concentration should be reduced after the filmforming to keep up the movie. The goal of this process is to rapidly type a protective film on the metal surface and improve the effectiveness of the corrosion inhibitor.
In one word, we should not only attach much importance towards the therapy approaches of cooling water, but also pay severe attention to the upkeep of circulation cooling water system.
