摘要：开发了烧结型表面多孔高通量换热管及其换热器。以乙醇为介质评价了表面多孔换热管的沸腾传热性能。研究表明,表面多孔换热管强化传热效果显著,在酒精中的传热效果是光管的8.7～12.1倍。以1.8 g/L CaSO4盐溶液为介质经240 h阻垢性能试验,结果表明表面多孔换热管具有良好的抗垢性能,在溶盐中多孔管沸腾传热系数始终大于光管的沸腾传热系数。工业化应用考核表明,采用该烧结型表面多孔换热管设计制造的高通量换热器,不仅可以大幅度提高相关流程装置的产能,而且可以明显降低能耗。
Heat exchanger is widely used in industries of petrochemical processing,chemical engineering,natural gas,metallurgy,electric power,etc.It is of crucial importance for industrial energy saving to improve the heat exchanging efficiency.Sintered porous surface tube and high flux heat transfer exchanger were innovatively developed.Boiling heat transfer characteristic of the sintered porous surface tube was evaluated with alcohol.Porous surface tube possessed outstanding heat transfer ability with a multiple of 8.7～12.1 compared with conventional tube.Fouling characteristic of the tube was evaluated in water dissolved 1.8 g/L CaSO4 for a test period of 240 hours.Porous surface tube possessed anti-fouling ability with consistently large heat transfer coefficient compared with conventional tube.High flux heat transfer exchanger was designed and manufactured with the porous surface tubes.It is found from industrial application that the high flux heat exchanger not only significantly improved the capacity of related unit,but also evidently reduced energy consumption.
