An important factor in choosing a plate heat exchanger is to look at the heat transfer efficiency of the equipment. It is important to know how the work efficiency of the equipment can directly reflect the heat transfer efficiency. Moreover, after understanding the heat transfer efficiency of the plate heat exchanger, the use of the plate heat exchanger will achieve twice the result with half the effort.
(1) The heat transfer efficiency of the plate heat exchanger is high, and the heat transfer area per unit volume is large, which is 2 to 5 times that of the tube heat exchanger.
(2) The heat exchange area can be greatly reduced, the volume of the plate heat exchanger with the effect of different heat exchange is greatly reduced, and the maneuvering space is also reduced accordingly, which increases the occupied air volume and reduces the civil construction degree.Since it is composed of many plates, it does not require a large inspection space, so that the total air-to-air ratio heat exchanger is increased by 2 to 3 times.
(3) If the range is 400,000 tons of coking, the crude benzene condensation cooler of the crude benzene section has a large heat exchange area and a reduced volume.Since it is arranged on the frame, the manipulation volume and the inspection space are greatly reduced after use.
The plate heat exchanger has high heat transfer efficiency and is a practical heat exchange device. The work efficiency is an important use knowledge, so it needs to be firmly grasped, and the equipment can be fully understood before the equipment can be fully utilized.
