Under random packing works Hualai tower internal liquid collector
1. Chevron liquid collector brief view:
| Tower Internal Type | Low pressure drop liquid collector tray |
| Column Diameter | ＞ 1000 mm |
| Liquid Range | 0.5 - 30 m3 / (m2*h) |
| Support at shell | A circular trough is welded to the column shell. This acts as support of the chevron collecting devices that bring the liquid into the channel |
| Construction Type | Like a chimney tray it is designed in parts to pass through the
column manway and to be bolted to the support |
| Design | Light gage metal collector acting only as liquid collector. The open area is extremely high and results in a very low pressure. |
| Application | Typical application is below packed beds to collect the liquid
coming from the bed. It cannot be considered a vapor distributor since the pressure drop is minimal and not enough to uniform the gas flow. |
2. Chevron liquid collector working principle:
The liquid falling from the upper packing is collected by the liquid collecting plate, flows through the lower liquid guide tank and then into the bottom liquid collecting tank in the center. When the diameter of the tower is large, in addition to the center collecting tank, the surrounding ring collecting tank is also set, and the collecting shutter is fixed on the middle horizontal tank and the ring groove. The liquid collected by the liquid collecting plate flows into the horizontal groove and the annular groove, and then flows into the redistributor below through the central tube of the horizontal groove to mix and redistribute the liquid.
3. Chevron liquid collector is vital tower internal:
There is a certain limit on the height of each section of tower packing, which is generally equivalent to 15-20 theoretical plates, that should be divided into sections. Therefore, liquid collector and liquid redistributor are indispensable tower internals.
In the down flow of liquid in the tower, there may be uneven distribution, resulting in uneven liquid concentration on the cross section of the tower. The liquid collection redistributor can completely collect and mix the liquid phase with uneven flow rate and concentration, which is beneficial to give full performance regarding to the separation efficiency of the tower. In addition, the rising gas must be evenly distributed in the upper packing, and the resistance is smaller.
