Introduction
Semi-circular plate and shell heat exchanger is a specially engineered plate-and-shell heat exchanger ideal for demanding duties, such as corrosive, high pressure and high temperature applications. Incorporating many innovative features to optimize customers' process performance, it takes the plate-and-shell concept to a new level. with its laser-welded plates and many multiple pass and asymmetric flow capabilities, allows optimization of thermal efficiency and substantially improved fatigue resistance. Designed for use with liquids, gases and two-phase mixtures at pressures up to 100barG (1,450 psiG), in both PED and ASME, and at temperatures up to 450 °C (842 °F), it is suitable for a wide range of aggressive media. Its capabilities reach far beyond both gasketed and many other welded heat exchanger technologies
Advantages:
Technical parameters
| design temperature: -196 ºC ~ 450 ºC |
| design pressure: Vacuum ~ 4.5MPa |
| assembly area: ≤5000m2 |
| minimum temperature difference: 1 ºC |
| plate thickness: 0.7 ~ 1.0mm |
Structures
a lot of structure, process composition not only diverse, but the shell structure can also be designed according to the requirements of process conditions, by changing the direction of flow baffles to achieve the best heat transfer |
the product consists of the heat exchanger core, shell, pressing plate, bearing plate, baffle plates, end plates, flanges, clamping studs, brackets and other components |
the entire surface of all-welded plate almost use to heat exchange,this can make full use of metal materials. This all welded plate heat exchanger is without flow dead zone, this can provide high efficient heat exchange capacity in the low pressure drop, and can achieve very small temperature difference heat transfer requirement. |
the layout of the plate is formed into an oval pipe on the pipe flow side, and S shaped channel is formed at the side of the plate. Plates' corrugated depth can be adjusted in order to meet the requirements of large flow, low pressure drop or larger particles in the fluid |
Flow pattern
The flow method of two mediums in flow passage is the combination of crossflow and baffle,but the two sides' two fluid can reach complex multi path layout
