Liquid distributor

The liquid distributor is one of the internal parts of the tower. The liquid distributor distributes the liquid evenly on the surface of the packing to form an initial distribution of the liquid during the operation of the packed tower. The initial distribution of the liquid has a great influence on the performance of the packed tower. The most important tower internals. Generally speaking, for difficult-to-separate systems, high-efficiency packing, large-diameter, low-layer packing towers, high liquid uniformity is required. Therefore, sufficient attention must be paid to the design, manufacture and installation. The trough-type liquid distributor is a gravity-type liquid distributor. The trough-type liquid distributor is usually composed of a distribution tank (also called a main tank or a primary tank) and a distribution tank (also called a secondary tank or a secondary tank). The first-level tank divides the liquid into a number of streams through the opening at the bottom of the tank, and respectively introduces them into the liquid distribution tank below it. The groove bottom (or groove wall) of the distribution groove is provided with holes (or pipes) to evenly distribute the liquid on the packing layer. The trough-distributor is a new type of liquid distributor developed by our country in recent years. It organically combines the advantages of trough-type and disk-type distributors. It has three functions of liquid collection, liquid separation and gas separation, and has a compact structure. High operating flexibility. The gas-liquid distribution is uniform, the resistance is small, and the space occupation is low. It is especially suitable for occasions that are prone to entrainment and clogging. It is very suitable for a tower with multiple feeds and extractions.
