Can a closed cooling tower be used for sewage cooling?
Sewage, in simple terms, is polluted water, including domestic sewage, production wastewater, chemical wastewater, printing and dyeing wastewater, etc., but they all have a common feature: it contains a variety of impurities or chemical components. If this kind of sewage is directly discharged into the environment, it will not only cause the waste of water resources, but also pollute our living environment.
Sewage, in simple terms, is polluted water, including domestic sewage, production wastewater, chemical wastewater, printing and dyeing wastewater, etc., but they all have a common feature: it contains a variety of impurities or chemical components. If this kind of sewage is directly discharged into the environment, it will not only cause the waste of water resources, but also pollute our living environment. At the moment when the country vigorously promotes environmental protection, companies must find a better way to treat sewage in order to survive for a long time. Some people think of the reuse of sewage, but how to reuse it?
The sewage produced by the production process generally has heat and high temperature, so we filter the sewage in the sewage pool to remove impurities, and then pump it into the closed cooling tower by the circulating water pump. After cooling, it flows out from the lower outlet of the closed cooling tower and flows into the sewage pool, and then the sewage in the sewage pool is pumped into the closed cooling tower by the circulating water pump, thus repeating the circulating cooling.
Due to the different chemical composition of the sewage, we have different material requirements for the core component of the closed cooling tower-the cooler coil. There are 314 stainless steel, 316 stainless steel, 316L stainless steel, deacidification copper pipe, carbon steel, titanium steel, etc. A variety of choices.
According to 20 years of supporting experience, the main reason is that the sewage composition is complex, the use of open cooling towers, circulating work in an open environment, it is easy to cause filler fouling, greatly affecting the cooling tower heat transfer effect and service life. The water circulation of the closed cooling tower is carried out in a closed space, which can effectively avoid the problem of scaling.
