根据微膜热虹吸两相流传热强化机理，在１５０ｍ３／ｈ制氧装置上首次采用类环状流新型冷凝蒸发器替代烧结多孔表面管冷凝蒸发器，使得冷凝侧和蒸发侧总传热温差仅为１．１６Ｋ～１．２５Ｋ，其性能达到目前最为优越的烧结多孔表面管冷凝蒸发器的水平．同时．使冷凝蒸发器的重量和体积均减少１／３，制造成本每台节约２万多元．使用新的冷凝蒸发器后．氧气产量达到１７５ｍ３／ｈ，各项指标均超过原有１５０ｍ３／ｈ制氧装置的设计指标． According to the heat transfer enhancement mechanism of the microporous thermosyphon two-phase flow, a new type of annular flow condensing evaporator is replaced by a new type of annular flow condensing evaporator on the 150m3 / h oxygen making device so that the total heat transfer temperature difference between the condensing side and the evaporating side is only For 1.16K ~ 1.25K, the performance reached the most superior sintered porous surface tube condensing evaporator level. Simultaneously. So that the weight and volume of the condensing evaporator are reduced by 1/3, manufacturing cost savings of more than 20,000 yuan each. After using the new condensing evaporator. Oxygen production reached 175m3 / h, the indicators are more than the original 150m3 / h oxygen plant design specifications.
