Plastic Trough Liquid Distributor Product Description

The Plastic Trough Liquid Distributor is a corrosion-proof column internal designed to evenly distribute liquid across the full cross-section of a packed bed in aggressive chemical environments. Constructed entirely from PP, PVC, PVDF, or PTFE, it consists of a network of parallel troughs with precisely machined V-notches or perforations. Liquid enters via a main feed pipe, fills the troughs, and overflows uniformly onto the packing surface, ensuring optimal gas-liquid contact and mass transfer efficiency. Its all-plastic construction provides absolute immunity to acids, alkalis, and solvents, making it the definitive choice for strong acid scrubbing, chlorine drying, and chemical absorption columns where metal distributors would rapidly corrode.

Product Highlights

• Universal Corrosion Resistance: All-plastic construction in PP, PVC, PVDF, or PTFE resists all inorganic acids, alkalis, and most organic solvents, ensuring maintenance-free operation in the harshest chemical environments.
• Uniform Liquid Distribution: Precision-engineered V-notches or perforations deliver even liquid flow across the full column cross-section, eliminating dry spots and maximizing packed bed efficiency.
• Anti-Clogging Design: Open trough channels and V-notch overflow geometry naturally resist solids build-up, maintaining reliable distribution even in moderate fouling services.
• Wide Turndown Ratio: Capable of maintaining distribution quality across varying liquid flow rates, accommodating plant turndown without compromising column performance.
• Lightweight & Easy Installation: Weighing only a fraction of metal equivalents, plastic distributors are easy to handle, install, and level, reducing structural load on the column.
• Customizable Layout: Trough spacing, notch density, and dimensions are fully tailored to specific column diameter and liquid load for optimal performance.
