摘要：【中文】本发明公开了石油化工装置中的一种含有独立导流板的逆流式板式换热器，包括传热板片，密封垫片，固定压紧板，活动压紧板，压紧螺栓和螺母，上下导杆，其特征在于：所述传热板片的导流区为平整板，在传热板片的导流区固定安装有独立导流板，所述独立导流板的厚度与传热板片的厚度相同，独立导流板的形状与传热板片的导流区的形状一致。采用本发明一种含有独立导流板的逆流式板式换热器的优点是，入口处独立导流板的导流效果好，流体分布均匀，能有效减小板式换热器的换热死区，提高换热效率。 【EN】The invention discloses a counter-flow plate heat exchanger containing an independent guide plate in a petrochemical device, which comprises a heat transfer plate, a sealing gasket, a fixed compression plate, a movable compression plate, a compression bolt and a nut, and an upper guide rod and a lower guide rod, and is characterized in that: the flow guide area of the heat transfer plate is a flat plate, an independent flow guide plate is fixedly arranged in the flow guide area of the heat transfer plate, the thickness of the independent flow guide plate is the same as that of the heat transfer plate, and the shape of the independent flow guide plate is the same as that of the flow guide area of the heat transfer plate. The counter-flow plate heat exchanger with the independent guide plates has the advantages that the independent guide plates at the inlet have good guide effect, the fluid is uniformly distributed, the heat exchange dead zone of the plate heat exchanger can be effectively reduced, and the heat exchange efficiency is improved.
