Water treatment equipment,plate heat exchanger for heating and
cooling
Product Description
Every plate is equipped with gasket,restrict the flow of media
within the plate group.
The gasket is designed as a double seal structure and has Signal
hole.If the media leak,
It can early find and solve the question, don't lead to a mixture
of two media.

Providing Plate and Gasket for Full Makes
Plate type selection
The plate type or corrugated type shall be determined according to
the actual needs of heat exchange occasions. For the case of large
flow and small allowable pressure drop, the plate type with small
resistance shall be selected, on the contrary, the plate type with
large resistance shall be selected. According to the fluid pressure
and temperature, decide whether to choose the detachable type or
the brazed type. When determining the plate type, the plate with
too small single plate area should not be selected to avoid
excessive number of plates, small flow rate between plates and low
heat transfer coefficient. This problem should be paid more
attention to for larger heat exchangers.
Selection of process and runner
Flow refers to a group of parallel flow channels in the same flow
direction of a medium in the plate heat exchanger, and the flow
channel refers to the medium flow channel composed of two adjacent
plates in the plate heat exchanger. Generally, several flow
channels are connected in parallel or series to form different
combinations of cold and hot medium channels.
The process combination form shall be determined according to the
calculation of heat exchange and fluid resistance and meeting the
requirements of process conditions. Try to make the convection heat
transfer coefficient in the cold and hot water channels equal or
close to each other, so as to obtain the best heat transfer effect.
Because when the convective heat transfer coefficient on both sides
of the heat transfer surface is equal or close, the heat transfer
coefficient obtains a larger value. Although the flow velocity
between the plates of the plate heat exchanger is different, the
average flow velocity is still used in the calculation of heat
exchange and fluid resistance. Because the connecting pipes of "U"
single process are fixed on the compression plate, it is convenient
to disassemble and assemble.
Pressure drop check
In the design and selection of plate heat exchanger, there are
certain requirements for pressure drop, so it should be checked. If
the check pressure drop exceeds the allowable pressure drop, the
design and type selection calculation shall be carried out again
until the process requirements are met.
Computing method
The calculation of heat transfer coefficient and pressure drop is
obtained from the performance curve of products of various
manufacturers. The performance curve (criterion correlation)
generally comes from the performance test of the product. For the
plate type lacking performance test, the criterion correlation of
the plate type can also be obtained according to the characteristic
geometric size of the plate type through the reference size method,
which is adopted by some general software in the world.
Selection software
As for the selection software of plate heat exchanger, the
manufacturer has its own selection software according to its own
plate type.
