Product Feature
1. High Distribution Density and Excellent Uniformity
Trough-type distributors achieve liquid distribution through numerous distribution holes (or overflow weirs) at the bottom of the trough, with a distribution point density of 100–500 points/m², far exceeding that of pipe or spray distributors. This high-density distribution ensures a uniform spray field across the initial cross-section of the packing layer, fundamentally eliminating efficiency reduction caused by uneven distribution.
2. Gravity-Driven Flow, No Entrainment
Trough-type distributors rely on gravity to allow liquid to fall into the packing layer in droplets or lines, rather than through nozzle atomization. This characteristic completely avoids entrainment, preventing tiny droplets from being carried into the gas phase outlet, making it particularly suitable for applications sensitive to entrainment, such as top distillation and high-purity separation.
3. Wide Operating Flexibility, Adaptable to Load Fluctuations
The distribution quality of a trough-type distributor primarily depends on the liquid level within the trough. AYRTTER trough distributors, through their optimized trough dimensions and orifice design, maintain stable distribution uniformity within a design load range of 30%–120%, offering operational flexibility of over 4:1 to adapt to fluctuations in raw material composition and throughput.
4. Strong anti-clogging capability and easy maintenance
The orifice diameter is typically 6–15 mm (adjustable according to the solids content of the medium), significantly larger than the nozzle orifice diameter of nozzle distributors. For media containing small amounts of solid particles, polymers, or prone to scaling, trough distributors exhibit excellent anti-clogging performance. Even if individual orifices become clogged, adjacent orifices can still handle excess flow, resulting in minimal decrease in overall distribution uniformity.
5. Stable liquid level and high distribution accuracy
Trough distributors maintain a stable liquid level within the trough under design conditions, with minimal impact of level fluctuations on distribution uniformity. AYRTTER trough distributors can be equipped with level adjustment devices (overflow plates or adjustable weirs) to further ensure consistent liquid levels in each trough, achieving high-precision liquid distribution.
6. Robust Structure and Easy Installation
The tank body is constructed from welded or riveted metal plates, providing high overall rigidity and withstanding the impact of liquid gravity and airflow. The modular design allows for segmented manufacturing and on-site assembly, suitable for various tower diameters (from small towers of 300mm to large towers of over 10000mm).
7. Diverse Materials for Corrosive Conditions
AYRTTER gravity-fed trough distributors can be made from a variety of metal materials depending on the media environment.
Suitable Media Types
Clean or low solids content liquids
Medium solids content (with overflow weir)
Easily polymerizable and scaling media (with large orifice or overflow weir)
High viscosity liquids (requires special design)
Corrosive media (select corrosion-resistant materials)
Manufacturing Process and Quality Control
AYRTTER gravity channel distributors employ a rigorous manufacturing and inspection process:
1. Design Calculations: Hydraulic verification, orifice calculation, strength verification
2. Material Selection: Selecting suitable materials according to operating conditions and providing material certificates
3. Precision Machining: CNC cutting, bending, punching, accuracy ±0.5mm
4. Welding Assembly: Argon arc welding/CO₂ shielded welding, smooth welds without deformation
