Analysis of the reasons for the convenient installation and cleaning of plate heat exchangers

The plate heat exchanger has a small footprint, convenient cleaning, a wide range of applications, and a long service life. Under the same pressure loss, the heat transfer coefficient is 3 to 5 times higher than that of the tube heat exchanger, and the footprint is small. A third of the tubular heat exchangers have a heat recovery rate of more than 90%.



As plate heat exchangers have the advantages of high thermal efficiency, compact structure, convenient cleaning and disassembly and maintenance, simple changes in heat exchange area or process combination, and no dead space for disinfection, they have been widely used by most manufacturers such as biological fermentation and heating. In view of this, we will discuss and discuss the selection, evaluation, installation, protection and maintenance of MSG professional plate heat exchangers.


In order to deal with the dripping phenomenon caused by the aging of the gasket, the plate heat exchanger should adjust the sealing function of the heat exchanger, that is, tighten the bolts of the combined plate heat exchanger again and adjust the pressure. Elastic gasket between heat exchangers. Tighten to handle dripping. On the nameplate of a heat exchanger with this function, the maximum and minimum stresses are usually given.


For new heat exchanger chip sets, the joint should be secured with the minimum allowable stress. According to the number of heat exchangers in each group, the tightening force of the plate heat exchanger can be adjusted once or repeatedly. The nut can be tightened by 3 mm each time the nut is tightened, and the stress state will always be observed during the tightening process. Surface tension, and only take over the heat exchanger without working pressure, adjust the tightening force at room temperature to avoid dripping.
