SS304 Random Packing Supporting Plate Grid Plate Type Hump Support
1. Random Packing Supporting Plate Grid Plate Type Hump Support
The main purpose of the packing support plate is to support the
packing in the tower, and at the same time to ensure the smooth
passage of gas and liquid phases. If the support plate is not
designed properly, flooding will first occur on the support plate.
For ordinary packing, the free cross-sectional area of the support
plate shall not be less than 50% of the total tower cross area, and
shall be greater than the free cross-sectional area of the packing
layer. The basic requirements are:
1. It has enough strength and rigidity, and can support the quality
of packing and liquid holding as well as the operating pressure,
etc;
2. It has an opening ratio greater than the void ratio of the
packing layer to prevent flooding at this position;
3. The structure is reasonable, which is conducive to the uniform
distribution of gas and liquid phases, small resistance and easy to
disassemble.
The commonly used packing supporting devices are grid plate type,
beam type, etc. The selection of the supporting device depends on
the tower diameter, packing type and the range of gas and liquid
flow.
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.
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.

To be continued. |
When the tower inner diameter is over 2600mm, main bearing beam
under the beam supporting plate is required.
3. Features of beam type random packing support plate
1. Good rigidity and large capacity.
2. The pressure drop of gas through the support plate is small.
3. The gas and liquid flow channels are separated, and the gas
phase is sprayed to the packing layer through the side opening
holes, while the liquid phase flows to the lower packing layer
through the opening at the bottom of the support plate, so the gas
and liquid are evenly distributed
4. The free cross-sectional area of gas-phase flow is large.
Generally, the free cross-sectional area can reach more than 90% of
the cross-sectional area of the tower, so a higher gas-liquid load
is allowed.
4. Applications
Distillation towers, scrubbing towers, steam drum, evaporators,
knockout drum, sulfuric acid plants, petrochemical plants, flue gas
desulfurization, refineries,LNG plants,etc.
