Troughed disc liquid distributor is a patented product that represents a new advancement in disc liquid distributors. It is named the "Troughed Disc Liquid-Vapor Distributor" because it is a disc-type distributor assembled and welded from a number of distribution slots, serving the functions of collecting, distributing liquid, vaporizing, and side-line extraction.
The structural features of the槽盘式气液分布器:
The槽盘式气液分布器 consists of rectangular riser pipes, angle and channel steel guide liquid pipes, dovetail or channel steel liquid retaining caps, laying plates, support rings, and support beams. Its main difference from the disk-type liquid distributor lies in the two rows of small holes, which are larger at the top and smaller at the bottom, and are located at the upper, middle, or lower middle sections of the rectangular riser pipes. The uneven-sized holes along the same vertical line are covered by angle or channel steel guide liquid pipes. The liquid in the disk enters the guide pipe through the spray holes, protected by the guide pipe as it passes through the high gas velocity and variable gas velocity zones, and falls from the low gas velocity zone. Therefore, the extended length of the guide pipe is taken as 100mm.
The classifications of slot tray gas-liquid distributors: Welded slot trays and detachable slot trays. Large and medium-sized towers typically use welded slot trays.
The slot disk gas-liquid distributor has four major technical keys: leakage, levelness, thermal deformation, and liquid flow network. Detachable slot disks are more prone to leakage than welded slot disks, and the on-site leakage test requires that local seepage is acceptable, while dripping is unacceptable. For detachable slot disks, due to the thin bottom plate, even with tightly spaced bolts, it's difficult to ensure no dripping, so segmented flanges should be used to enhance sealing. To ensure the levelness of the spray holes in the slot disk gas-liquid distributor is ≤3mm, in addition to ensuring the deflection of the main beam and the levelness of the support ring, a regulating plate should be set on the upper surface of the main beam. For large quantities of slot disk gas-liquid distributors (or oil collection tanks), a meticulously designed liquid flow network consisting of extraction troughs, main channels, branch channels, and primary channels is necessary to ensure high output.
A槽盘式 gas-liquid distributor is an internal recirculation liquid distributor with the following excellent comprehensive performance:
Low footprint, multi-functional; anti-clogging, with liquid stop; rising liquid level, high elasticity; easy to extract, suitable for flash vaporization; liquid even, gas balanced; conducive to heat transfer, resistant to vibration; good mixing, level constant; leak-proof, resistant to deformation; mesh channel smooth, suitable for reaction; pressure reduced, flux increased; wide application, cost-effective.
