Air to air heat exchanger cold room evaporator copper tube bundle
Tubular Heat exchanger is one of the most widely used heat
exchangers in chemical and alcohol production. It is mainly
composed of shell, tube plate, heat transfer tube, head, baffle and
other components. The required material can be made of ordinary
carbon steel, copper, or stainless steel, respectively.
Tubular heat exchanger structure is relatively simple, compact,
cheap, but the tube can not be mechanical cleaning. The heat
exchanger tube bundle is connected to the tube plate, and the tube
plate is welded at both ends of the shell, and the top cover and
the shell are connected with fluid inlet and outlet.
A series of baffles that are perpendicular to the tube bundle are
usually provided outside the tube. At the same time the pipe and
the tube plate and the shell connection are rigid, and the tube
tube is two different temperature fluid. Therefore, when the
temperature difference between the wall and the shell wall is
large, due to the different thermal expansion of the two, resulting
in a large temperature stress, as well as the tube twist or pipe
from the tube board loose, or even destroy the heat exchanger.
In order to overcome the temperature stress must have a temperature
compensation device, generally in the wall and the wall temperature
difference of 50 ℃ or more, for safety reasons, the heat exchanger
should be temperature compensation device.
But the compensation device (expansion joint) can only be used in
the shell wall and wall temperature difference of less than 60 ~ 70
℃ and shell fluid pressure is not high case. General shell pressure
exceeds 0.6Mpa when the compensation circle is too thick, difficult
to stretch, loss of temperature compensation role, you should
consider other structures.
