random packing hump support
Innovated simple structure economic random packing hump support
1. Random Packing Hump Support 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.

3. Hualai innovation in random packing hump support:
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. They are suitable for cases without heave burden, and requires more economic solutions. 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.
4. Random packing hump support details:
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.

When the tower inner diameter is over 2600mm, main bearing beam under the beam supporting plate is required.
