Plate Shell Heat Exchangers For Chemical Industries , Shell And Tube Heat Exchanger
 
Plate & Shell Heat Exchanger integrates the advantages of plate heat exchanger and tube & shell heat exchanger as a whole. Owing to such advantages as high efficient heat transfer, close approach temperature, high pressure & heat resistance, compact structure and light weight and etc., it has been widely applied in power, petrochemical, steel, food and pharmaceutical industries and etc. The plate & shell heat exchanger developed by SMDERI is constructed with corrugated sheets similar with plate type heat exchanger. All round sheets are welded to each other into a lamella bundle and then mounted into a shell. There is no gasket between sheets so that it is suitable for high temperature & pressure applications where conventional plate frame heat exchangers can’t be used.
 
 
Work Principle / Flow Process

• Plate & Shell Heat Exchanger consists of a vessel shell and a heat exchanging core mounted into the shell. The core actually is a lamella bundle made by welding multiple layers of round & corrugated metal sheets of 0.8-1.2mm thick together.
• Neighboring sheets establish narrow and tortuous channels in between and allow the working fluid to flow through.
• The cold fluid and hot fluid flow through its own channels in order. The cold and hot channels are separated by the sheet naturally, where heat exchange takes place.
• The structure and work principle of Plate & Shell Heat Exchanger determines that it has the advantages of high heat & pressure resistance, compact structure, small footprint, high heat transfer efficiency, flexible operation, wide application, low heat loss, easy installation & cleaning, etc.

 
Advantages

1. Laser welded lamella bundle as the core of heat exchanger – High heat & pressure resistance;
2. Cylindrical structure – well-distributed stress, fatigue & heat stress resistance, and applicable for intermittent operation;
3. Removable core of heat exchange – Easy cleaning & maintenance at shell side;
4. Pressure vessel as shell – safe and reliable;
5. Multi flowing channels at both plate side and shell side – Temperature cross is realized;
6. Streams may be designed to have different flow directions, i.e. the same, opposite or cross directions; ;
7. Rich manufacturing experience – Safe and reliable products are fabricated;
8. Sufficient inventory of spare parts – Short lead time is required;
9. High management efficiency – Low cost of products is resulted.
