Description: Installed above packing‑layers or inter‑packing‑sections within corn‑starch washing towers. Dual‑function component: it uniformly distributes incoming starch‑slurry and circulating wash‑water across full tower cross‑section to suppress channeling and maldistribution and preserve packing‑bed mass‑transfer washing efficiency. Meanwhile integrated tempered sight‑glass windows enable direct external visual inspection of distributor liquid‑level, liquid‑dispensing status, blockage‑and‑fouling conditions. Condition monitoring is achievable without tower shutdown or vessel opening, supporting predictive‑maintenance decision‑making and securing production stability.
Core has. Combined liquid-distribution & visual-inspection functionality: Integrates sight-glass observation module onto conventional liquid-distributor hardware.
Delivers homogeneous liquid spreading together with real-time process-visualization capability lowering shutdown-maintenance frequency.
Starch-process anti-clog design: Large-orifice liquid-distribution hole/overflow-weir geometry; wide open-flow-paths free of narrow gaps.
Resists blockage from starch-granule and fine-fiber loading for continuous solids-bearing-media service. Food-grade hygienic compliance: Process-contact main body constructed from 304/316L food-grade stainless-steel.
Sight-glass uses tempered borosilicate glass; sealing gaskets satisfy food-contact-safety-specifications, free of sanitary dead-zones.
Pressure-tight reliable sealing: Multi-stage food-grade sealing construction at sight-glass joints tolerates tower-internal pressure-and-temperature excursions.
Zero leakage and internal-fogging over long-term runtime. Service-friendly maintainability: Sight-glass hold-down cover can be rapidly disassembled for glass-surface cleaning.
Modular distributor-main-body facilitates tower-internal hoist-out for overhaul and sediment-removal cleaning.
Structural composition. Distributor main-body: Trough-style/pipe-header-style liquid-dispensing hardware for staged flow-splitting and uniform liquid spreading.
Sight-glass assembly: Tempered borosilicate sight-glass panel stainless-steel compression retainer food-grade sealing gaskets for process-condition visualization.
Inlet flow-splitting header: Receives incoming tower-feed and first-stage coarse flow-distribution. Liquid-distribution orifices/overflow-weir notches: Final-stage spreading of liquid onto underlying packing-bed.
Support-and-positioning frame: distributor mounting inside tower mechanical support and horizontal-level calibrationMainstream structural types (commonly used in starch washing towers)
1. Trough-type sight-glass distributor: Gravity overflow-weir liquid-dispensing principle.
Broad operating turndown ratio and high dirt-holding-capacity. Sight-glass windows are aligned over primary liquid-holding trough permitting direct observation of liquid-level height and distribution-uniformity.
Preferred hardware for large-/medium-diameter corn-starch washing-towers; well-suited for coarse-wash-section duties with elevated fiber-and-starch-particle loading.
Pipe-header sight-glass distributor: Liquid-dispensing built upon main-header plus parallel branch-pipe layout.
Sight-glass windows positioned corresponding to spray-distribution zones permitting direct visual check of spray-pattern and clog-status.
Simple construction and straightforward installation; suited for small-medium-diameter washing-towers or refining-section liquid-dispensing applications.
