The Cooling Tower Design Of Jianfeng Thermo-Power Plant

Cooling water tower is one of the basic facilities in modern industry. This paper has simply introduced the development of cooling tower technique, both at home and abroad. The advantages/disadvantages of typical acrossflow tower and counterflow tower, the advantages/disadvantages of splash packing and film packing. The design of Jianfeng Thermo-power plant has chosen the counterflow cooling tower incorporated the local atmospheric environment and the parameter of cooling water quality.According to circulating water flow and temperature, it concludes the cycle inlet water temperature is 43℃ and outlet temperature is 32℃, cooling water flow is 2300 m3/h each tower and total flow is 6900m3/h. In the design of cooling tower, the eathalpy difference method has been used to calculate the thermal performance, meanwhile the resistace performance of cooling tower also be calculated .After combination of the cooling tower technology at home and abroad, the cooling tower market and the result of thermal calculation, it finishes the general layout and arrangement of each main components of cooling tower, which uses reinforced concrete in site, counterflow and rectangular distribution, each cooling tower is separated by separating wall of reinforced concrete in site, each cooling tower's middle section from the top of sump to the top of cooling tower is separated by separating wall of reinforced concrete in site, cooling tower wall is surrounded byfibreglass reinforced plastic. The shower water packing is WS type, the packing height is 1.50 meter. It uses velocity recovery fan cylinder made by fibreglass reinforced plastic, diameter 7.70 meter and height 4.75 meter. It uses distribution system of fibreglass reinforced plastic pipe and three-way spray nozzle of ABS co-polyners. It uses S type drift eliminators PVC. It self-contains a fan each tower, diameter 7.70 meter and wind flow 190X104 m3/h. the power of motor is 90 kilowatts.Jianfeng Thermo-power Plant will be save 47196000 ton water to use circulating water and cooling tower.In comparison with other similar towers, this tower is characterized by stable whole structure, low resistance, uniform distribution of water and wind, improved tower type and structure, good corrosion resistant, safe to maintenance and operation.
