Bending 304 steel plate hump shape random packing support
1. Hump shape random packing support
The main purpose of the random 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.

When the tower inner diameter is over 2600mm, main bearing beam
under the beam supporting plate is required.
3. The basic requirements of hump shape random packing 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.
4. The most popular type of hump shape random packing support:
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.
