The closed cooling tower is a modification and development of the traditional cooling tower. The closed cooling tower carries the rich waste heat energy with the closed cycle process fluid. In the tube heat exchanger, that is, the coil, the heat exchange between the closed cycle fluid and the flowing air and spray water is completed to achieve the effect of heat dissipation and cooling. Compared with the open cooling tower, the closed cooling tower has the characteristics of good thermal performance, high process quality, and strong cooling efficiency. Generally speaking, the accessories of a closed cooling tower mainly consist of the following:
In the process of production and on-site construction of closed cooling towers, the most commonly used coils are copper, stainless steel, titanium alloy and aluminum alloy.
Copper profile coils, that is, pure copper profile coils. The copper coil is a seamless tube made of pure copper, that is, T2 deoxidized copper pressed and drawn. The T2 copper heat exchange coil has the advantages of good thermal conductivity, high strength, sturdiness, corrosion resistance, high stability and reliability, no leakage, no combustion support, and no toxic gas generation.
The stainless steel profile coil is a hollow long round steel, which is an economical section steel. Because the steel pipe has a hollow section, the stainless steel pipe is very suitable as a closed cooling tower coil. The stainless steel coils of closed cooling towers are characterized by resistance to rust, high strength, super corrosion resistance, abrasion resistance, excellent chemical resistance, good alkali metal and acid resistance, strong toughness, flame retardancy, and high temperature resistance.
The tower structure of a closed cooling tower consists of a box and a support. The tower body is generally made of hot-dip galvanized steel, with a surface coating, double-folding without welding, and the overall appearance is generous, super corrosion-resistant, and can be used for 15-20 years. The tower body can also be made of 201, 304 stainless steel partially or completely. The tower support frame is generally made of stainless steel, with a strong structure and durability.
The closed cooling tower adopts a high-efficiency airfoil FRP or alloy fan with suitable power, high wind speed and low speed. While ensuring the air volume, the air distribution reduces the noise pollution caused by the fan. The motor of the closed cooling tower has good insulation, good start-stop performance control, and stable operation, so a reducer should be properly configured.
The spray pipes of the closed cooling tower are all UPVC pipes, which are light in weight, small in water flow resistance, corrosion resistant, and can be used for more than 20 years. High-quality ABS sprinklers, uniform spraying, high flow coefficient, non-clogging, and easy to replace. The use of large flow and low head water pump, outdoor motor insulation, protection and safety. The stainless steel filter screen is used to effectively isolate the debris, and the water pump sucks water smoothly. The entire water pump device runs smoothly, reliably, safely and efficiently.
The water eliminator of the closed cooling tower adopts a high-efficiency PVC water eliminator, which has a low bleaching rate. The water eliminator is light in weight, non-corrosive, with an oxygen index greater than 40 and good flame retardancy.
