Tray distributor made of stainless steel 316L. Function: Distributor manufacturer

Description :

　　grooveplatedistributorhaveWelded groove discs and detachable groove discs. Large and medium-sized towers often use welded groove plates. The trough plate gas-liquid distributor has four technical key points: leakage, levelness, thermal deformation, and liquid flow network. Detachable groove discs are more prone to leakage than welded groove discs. On site leakage testing requires that local leakage is considered qualified, while dripping is considered unqualified. For detachable groove discs, due to the thin bottom plate, it is difficult to ensure no leakage even if the bolts are tight, so segmented flanges should be used to increase sealing. To ensure that the levelness of each spray hole in the trough plate gas-liquid distributor is ≤ 3mm, in addition to ensuring the deflection of the main beam and the levelness of the support ring, an adjusting plate needs to be installed on the upper end face of the main beam. For the extraction of a large number of trough type gas-liquid distributors (or oil collection tanks), it is necessary to carefully design a liquid flow network consisting of extraction buckets, extraction main channels, extraction branch channels, and capillary channels to ensure the required output.

　　Trough distributorDifference from trough distributor:

　　 The principle of liquid distribution is the same, but the gas channels are different.

　　 2. The distribution of both liquids is based on the principle of consistent liquid flow velocity at the same liquid level

　　 3. The gas in the trough distributor passes through between the troughs, and the trough plate distribution has a rising pipe as the gas channel

　　 4. The trough distributor and tower are point supports, while the rotary distributor needs to be welded to the tower.

　　 5. The trough type is more reliable, as improper installation of the trough plate may cause leakage.

　　 6. The trough type liquid distributor is a liquid distributor with excellent comprehensive performance. The trough type liquid distributor has the advantages of easy installation, uniform liquid distribution, high spray point density, and extremely low pressure drop, and is currently widely used.

　　 7. Tray type gas-liquid distributor combines the functions of liquid collector, liquid distributor, and gas distributor. It has the advantages of low space occupation, strong anti clogging ability, no liquid foam entrainment, high operational flexibility, and pressure reduction.

　　 The function of liquid distributor

　　When the liquid flows downwards in the chaotic packing layer, there is a tendency to gradually flow towards the tower wall, known as wall flow phenomenon. To improve the mass transfer efficiency of the tower, when the ratio of the height of the packing layer to the tower diameter exceeds a certain value, the packing layer needs to be segmented. To improve the uneven distribution of liquid caused by wall flow, liquid redistributors are installed between each packing layer to collect liquid from the previous packing layer and provide uniform liquid distribution for the next packing layer. A liquid redistributor should be installed at regular intervals in the packing layer.

　　In general, a liquid collector and a liquid distributor are used together to form a liquid collection and redistribution device. The function of the liquid collector is to collect the liquid flowing down from the upper packing layer and then send it to the liquid distributor for liquid redistribution.
