In shell and tube heat exchanger,
the shell usually a weak
link. Common
segmental baffle to shell fluid was "Z" shaped flow separator and
the shell, resulting in the formation of stagnant zones, there are
bypass fluid flow, leakage flow effects and the relatively high
back-mixing. The dead zone caused by increased shell scale,
bypass flow, leakage flow and back mixing makes the average
temperature and reduced
distortion. Therefore, the segmental baffle heat exchanger
heat transfer coefficient is low, the high pressure drop, it is
difficult to meet the requirements of high thermal efficiency,
Guchang for other types of heat exchanger is replaced (such as
compact plate heat exchanger).
Ordinary baffle geometry improvements, is the
first step in the development of the
shell. Czech first proposed a helical baffle heat
exchanger new program, then, ABB bought the U.S. patent and helical
baffle heat exchanger
manufacturing. Fluid dynamics and heat transfer test results
show that the helical baffle heat exchanger to overcome common
segmental baffle heat exchanger main drawback, is an ideal shell
supporting structure bundle.
Spiral baffle design principle is simple: the
circular cross section of the special plates installed in the
"proposed Helical System", each baffle shell heat exchanger in the
total cross-section of a quarter, its inclination
towards axis of heat exchanger, ie heat exchanger to
maintain a tilt axis. Adjacent baffle surrounding phase, and the
External Department into a continuous spiral.Axial baffles overlap, For narrow to support
the pipe span, can also be double-helical baffle
design.
Helical baffle structure can meet the relative
width of the process
conditions. This design has great flexibility, for
different operating conditions and choosing the best helix angle,
can be divided to choose a single or double helical baffle
baffles. If we helical baffles and enhanced tube with,
can further enhance the overall heat transfer
coefficient.
