U型管式換熱器
產品型號:U型管式換熱器
U型管式換熱器結構緊湊,體形小,節省站房用地面積和建筑高度(占地面積為一般管殼式換熱器的1/2 左右,高度可降30~40%)。節省建筑投資,便于設計布置,同時運行操作方便。換熱性能好,熱媒出口溫度低,熱能利用率高,節能效果好。傳熱系數高,節省換熱面積(TQN、TQK)汽水換熱器的傳熱系數(K值)比板式汽水換熱器的實際使用傳熱系數大一倍左右,換熱面積可減少40-60%。水力特性好,熱媒和被加熱水的流動阻力小,節能效果好。 U型管汽水換熱器排出的凝結水溫度低(TQK)系列在65℃以下,(TQN)系列在80℃ 以下,既無漏汽損失,也不需要裝疏水器,管道系統簡單,散熱損失小。
U型管汽水換熱器的管間間距比一般管殼式換熱器的管間間距大,每個換熱單元的尺寸和重量較小,便于維護清洗。
U tube heat exchanger structure is compact, small size, saving station building land area and the height of the building (which covers an area of over generally about half of the tube and shell heat exchanger, the height is 30 ~ 40%). Save construction investment, facilitate design layout, convenient for operating at the same time. Good heat transfer performance, low outlet temperature of the heat medium, high heat energy utilization, energy saving effect is good. Heat transfer coefficient is high, can save heat exchange area (TQN, TQK) soft drinks heat exchanger heat transfer coefficient (K value) larger than the actual use of board type soda heat exchanger heat transfer coefficient times the left and right sides, so the heat exchange area can reduce 40-60%. Good hydraulic characteristics, heat transfer and the heated water flow resistance is small, energy-saving effect is good. Soda u-shaped tube heat exchanger of the condensate temperature low (TQK) series under 65 ℃, (TQN) series under 80 ℃, no steam leakage loss, also do not need to install hydrophobic, pipeline system is simple, small heat loss.
U tube spacing between soft drinks heat exchanger tube than the average of tube and shell heat exchanger tube spacing between big, smaller size and weight of each heat exchange unit, easy to maintain clean.
