Energy-saving renovation of cooling towers
Thread Content
At present, circular water cooling towers are commonly used in chemical and metallurgical industries, and they are of the square counterflow forced ventilation type. Such towers experience high evaporation rates in summer; a large amount of cooling water is lost in the form of steam, causing significant losses for businesses and leading to substantial waste of water resources. Taking a cooling tower with a circulation rate of 34,000 tons per hour as an example, and assuming a temperature difference of 7°C, the evaporation rate in summer amounts to 428 tons per hour. Over a period of 3 months, the total amount of water lost amounts to 30,843 tons. Are there any specialized institutions currently researching and working on this topic? This is particularly important for power generation, the chemical industry, and metallurgy in water-scarce areas.
Energy conservation and reduction of waste – **advocated as the equipment and technologies that businesses seek**
Now there is a closed-loop water system, with no waste from water evaporation.
Companies are facing difficulties in survival and need to reduce energy consumption and emissions.
Most have been built; it’s best to have measures for renovation. It’s not that the cooling effect is worse than that of an open type.
The evaporation coefficient and concentration ratio of circulating water are important indicators affecting its consumption; it is believed that with the development and progress of society, good methods and measures will be found to reduce this consumption.
I look forward to new technologies being applied in this field.
There is a technology called mist removal towers that is worth knowing about~~ Additionally, in some fiberglass cooling towers, the baffles or packing materials age, which leads to poor heat exchange and high splash losses~~ It’s possible to try replacing the packing materials and repairing the baffles~~
What are the differences between filled and unfilled cooling towers?
Packed towers are cost-effective, have low pressure drop, and do not get clogged, but they consume a large amount of water. Packed towers have a large hydrophilic surface area, enabling good heat exchange; however, they require a large volume and thus higher investment costs. Water consumption is slightly better.
There is an environmental protection company in Wuhan, Hubei Zhongsheng Water Saving Co., Ltd. (http://www.whzseco.com), which specializes in energy-saving upgrades for cooling towers; you can check out their website.
