( Plate heat exchanger] Status quo of plate heat exchanger

by:DIGUANG     2020-03-31
Status quo of plate heat exchanger, plate heat exchanger in recent decades development soon, mainly manifested in the following respects. (1) more and more kinds of plate heat exchanger, the technical performance is getting better and better, the application scope is more and more widely. (1) the types of plate heat exchanger: look from the connecting way of plate heat exchanger: from detachable plate heat exchanger to brazing type plate heat exchanger. From half welded, full welded to the plate and shell heat exchanger. From the plate form: from symmetrical type development to asymmetric type. Look from the plate of the port: from symmetrical flow channel width port, port development to Eric. Looked from the depth of the plate corrugated: from wave deeply 3 ~ 5 mm plate to wave deeply commonly 2 ~ 2. 5 mm in shallow corrugated plate. (2) the plate heat exchanger of figure 1 - technical performance is getting better and better 1 plate heat exchanger design temperature, pressure range. Working temperature from 260 ℃ to detachable plate and shell type of 1000 ℃. Pressure from the detachable type 2. 5 mpa development to the plate and shell type 8. 0MPa。 Heat transfer coefficient from the 2000 w/m2? To 12000 w/m2 k development? k。 The largest equivalent 28 mm in diameter. The biggest detachable veneer so the heat exchange area of 4. 75m2。 Biggest welded veneer heat exchange area of 18 m2. Minimum brazing type single board so the heat exchange area of 0. 006m2。 Detachable largest single heat exchange area of 2500 m2. Most of welding type single heat exchange area of 10000 m2. on
