The liquid distributor is the key component in the packed column, which not only affects the mass transfer efficiency of the packing, but also affects the operating elasticity of the packing.

In order to reduce the amplification effect caused by poor liquid distribution and give full play to the efficiency of the packing, a liquid distributor must be installed in the packing tower to distribute the liquid evenly on the top of the packing layer. The quality of the initial liquid distribution not only affects the mass transfer efficiency of the packing, but also affects the operating elasticity of the packing. Therefore, the liquid distributor is a key component in the packed tower. There are many kinds of distributor, and the selection is mainly based on the distribution quality, operation elasticity, handling capacity, gas resistance, levelness and many other aspects

Liquid distributor classification:

1, according to the distribution of fluid power: gravity liquid distributor (hole type, weir type, pressure type liquid distributor, spray type, porous pipe type)

2. According to the shape of the distributor, it is divided into tube type, double row pipe, trough type, disc type, impact type, nozzle type, pagoda type, lotus type, combined type, etc.

3. According to the form of liquid leaving the distributor, it can be divided into: hole flow type and overflow type.

4, according to the number of liquid distribution points: single stage, multi-stage.

5. According to the combination of the distributor, it can be divided into tube groove type, hole groove type and trough plate type

Characteristics of tubular distributor:

1. Excellent liquid distribution performance, suitable for more spray points and low liquid load occasions

2. No solid particles are required in the material, and a filter screen should be set at the inlet of the riser

3. Tubular liquid distributor has good elasticity in operation

4. In the case of high operating elasticity, double row tube liquid distributor can be used

5. Suitable for large, medium and small tower

The material of pipe distributor is 304, 316, 316L and other stainless steel material
