Random packing supporting plate grid plate type and beam type

 

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.

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