Product Description

Product Description

The trough pan liquid distributor is usually composed of a diversion groove (also known as the main groove or primary groove) and a distribution groove (also known as the secondary groove or secondary groove Slot). The first stage slot initially divides the liquid into several streams through a hole at the bottom of the slot, and adds them to the liquid distribution slot below it. The bottom (or wall) of the distribution groove is equipped with holes (or conduits) to evenly distribute the liquid on the packing layer. The slot type liquid distributor has great operational flexibility and excellent anti fouling performance, especially suitable for separation fields with atmospheric liquid loads and liquids containing solid suspended solids and high viscosity. Due to the excellent distribution performance and anti fouling performance of the tower's internal components, the slot type distributor has a wide range of applications, with an opening rate of over 30%, an operating elasticity of 1: 1, and a pressure drop of 500pa.

Our Advantages

It has the advantages of more uniform gas and liquid distribution, reduced pressure, anti entrainment, low occupancy, and more convenient installation. It is also suitable for conditions such as feeding, side line extraction, and liquid collection and redistribution.
 

Working principle

The difference and working principle between trough type distributor and trough pan type distributor:
1. The principle of liquid distribution is the same, but the gas channels are different.
2. Both liquid distributions utilize the principle of consistent liquid velocity at the same liquid level
3. The gas in the slot distributor passes through the slots, and the slot plate distribution has an riser as the gas channel
4. The slot distributor and the tower are point supports, while the operating tray distributor needs to be welded to the tower.
5. The trough type should be more reliable, as improper installation of the trough pan type 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. Trough type gas-liquid distributor The trough type gas-liquid distributor combines the functions of a liquid collector, a liquid distributor, a gas distributor, and all three. It has the advantages of low occupied space height, strong anti clogging ability, no liquid droplet entrainment, high operating flexibility, and reduced pressure.

Applications:

Tower internals

Used as an internal component in chemical equipment such as desulfurization towers, distillation towers, and absorption towers for mist or dust separation, achieving air purification, flue gas desulfurization, and water purification treatment purposes.

Chemical industry

In the chemical industry, it is used in combination with wire mesh defoamers, wire mesh, and orifice corrugated fillers to eliminate or capture mist and liquid droplets entrained in the gas during processes such as catalyst and distillation, evaporation, and absorption.

Petroleum

Used for physical or mechanical separation of crude oil dehydration, crude oil degassing, and gas-liquid separation in the petroleum refining process.

Others

Separation and filtration devices in light industrial manufacturing processes; Even in fields such as medicine, aerospace, and machinery, they are widely used.
