Liquid distributors can be applied above each bed of packing in packed towers for being distributed uniformly.
Advantages :
Ekaislot Trough Type liquid distributorallows solids to settle above the floor of the trough, being applied for low to moderate fouling services.
Drip guideswill be placed outside the troughs, effectively eliminating liquid misdistribution and entrainment induced by the effects of vapor flow.
Feed Devices
The feed can be applied for liquid or vapor only , and mixed phases of liquid/vapor (flash feed),
Inlet feed device can be generally designed in pipe, vane, and deck type,etc.
Collector Trays
Liquid collectors can be generally applied between packed beds for partial liquid draw-off and/or to feed a liquid distributor below.
It can also be applied for total liquid draw-off to product or reboiler, or applied for liquid mixing.
Distillation column
The column internals provide a contact place for mass transfer and heat transfer for the gas-liquid phase and liquid-liquid phase; There are two main types of column internals: packed column and trayed column. The packing column internals mainly include packing, liquid distributor, liquid collector, redistributor, gas distributor, packing fastening device, packing support device; trayed column internals mainly include: tray, liquid collection tank (trayed column), tray support device (trayed column), feed distributor, gas feed and distribution device and mist eliminator.
Packed column
Working principle: The liquid is sprayed onto the packing from the top of the tower through the liquid distributor and flows down the surface of the packing. The gas is fed from the bottom of the tower, and after being distributed by the gas distribution device, it continuously passes through the gap of the packing layer with the liquid in a countercurrent manner, and on the surface of the packing, the gas-liquid two phases are in close contact for mass transfer.
