Hub and Lateral Screen
Description
The Hub and Lateral Screen (one of the water distributor) are the most critical internal parts in the filler tower, which not only affect the mass transfer efficiency of the filler, but also affect the operation elasticity of the filler.
In order to reduce the amplification effect caused by the poor distribution of the liquid and remain the efficiency of the filler, the Hub and Lateral Screen is a very critical internal part in the packed tower. There are many types of distributors. The main basis for selection are distribution quality, operation elasticity, treatment capacity, and gas resistance, etc.
Material
304, 304L, 321, 316L, 2205, 904L, Hastelloy, etc. The smallest slot size can reach 0.02mm.
Features
- Excellent liquid distribution performance, suitable for occasions with more spray points and lower liquid load.
- It is required that there should be no solid particles in the material, and a filter screen should be provided at the inlet.
- Good operation flexibility.
- Suitable for use in large, medium and small towers.
Type
- According to the fluid power of the distributor, the gravity type liquid distributor (hole type, weir type, pressure type, liquid distributor spray type, porous tube type)
- According to the shape of the distributor, it can be divided into pipe type, double-layer pipe type, groove type, disc type, impact type, nozzle type, pagoda type, lotus type, combined type, etc.
- According to the form of liquid leaving the distributor, there are split flow type and overflow type.
- According to the number of liquid distribution, it can be divided into single-stage and multi-stage.
- According to the combination of distributors, it can be divided into pipe groove type, hole groove type and groove plate type.
