When the tower inner diameter is over 2600mm, main bearing beam
under the beam supporting plate is required.
2. Basic requirements on random packing hump support:
- It has enough strength and rigidity, and can support the quality of
packing and liquid holding as well as the operating pressure, etc;
- It has an opening ratio greater than the void ratio of the packing
layer to prevent flooding at this position;
- The structure is reasonable, which is conducive to the uniform
distribution of gas and liquid phases, small resistance and easy to
disassemble.
3. Random packing support plate in distillation tower Introduction:
It provides physical support for the tower packing and the weight
of the liquid holdup. The packing support plate must allow both the
down-flowing liquid phase and up-flowing gas phase to go through
freely. Usually we use gas injection type of support plate for
random packing. There is separate passage for liquid and gas. And
we use flat bar welded grids as structured packing support. The
tower packing support plates have very high open area for liquid
and gas, so doesn’t add any significant pressure drop.
4. Random packing support plate structure in distillation tower
The commonly used packing supporting devices are grid plate type,
beam type, etc. But in Hualai factory, we develop some new types,
for which we cover crimped mesh on simple plate welded hump
structure.
The packing supporting grid plate composed of parallel slats is
simple in structure and convenient in manufacture, which is
commonly used in small tower. Grid type support plate is only used
in small tower because of its small opening rate and bigger flow
resistance to gas and liquid than other types.
5. Random packing support plate tecknical info:
At present, the best supporting device for random packing is beam
type supporting plate, which adopts beam type gas jet structure. It
is composed of beam-shaped elements, which are perforated on steel
plates with many long holes. The support plate is of gas-liquid
split type, in which the gas is ejected from the holes at the upper
part of each beam element, while the liquid flows down from the
holes at the lower part, avoiding the increased resistance when the
gas-liquid flows reversely through the same hole. Moreover, it can
provide more than 100% of the free cross-sectional area of the
tower, so gas-liquid flow resistance is small, and it is conducive
to gas-liquid redistribution. The flow capacity of the support
plate can reach 200 m3 / (M2 · h), and the maximum pressure drop is only 69 Pa.
