补充资料:双曲线型冷却塔
双曲线型冷却塔 hyperbolic cooling tower 火电厂、核电站的循环水自然通风冷却的一种构筑物。建在水源不十分充足的地区的电厂,为了节约用水,需设置冷却构筑物,以使从冷却器排出的热水在其中冷却后可重复使用。大型电厂采用的冷却构筑物多为双曲线型冷却塔。 英国最早使用这种冷却塔。20世纪30年代以来在各国广泛应用,40年代在中国东北抚顺电厂、阜新电厂先后建成双曲线型冷却塔群。冷却塔由集水池、支柱、塔身和淋水装置组成。集水池多为在地面下约2米深的圆形水池。塔身为有利于自然通风的双曲线形无肋无梁柱的薄壁空间结构,多用钢筋混凝土制造,塔高一般为75~110米,底边直径65~100米。塔内上部为风筒,标高10米以下为配水槽和淋水装置。淋水装置是使水蒸发散热的主要设备。运行时,水从配水槽向下流淋滴溅,空气从塔底侧面进入,与水充分接触后带着热量向上排出。冷却过程以蒸发散热为主,一小部分为对流散热。双曲线型冷却塔比水池式冷却构筑物占地面积小,布置紧凑,水量损失小,且冷却效果不受风力影响;它又比机力通风冷却塔维护简便,节约电能;但体形高大,施工复杂,造价较高。 |
