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.
