Dihydrate Extractor Agitators for Wet Process Phosphoric Acid (WPA) Plants

Product Name:Dihydrate Extractor Agitators for Wet Process Phosphoric Acid (WPA) Plants

Core Features:

1:High-Intensity Agitation of WPA Slurry: Provides vigorous fluid agitation for wet-process phosphoric acid (WPA) slurries with high solids content, eliminating stagnant zones within the tank.

2:Mixing of Reaction Components: Promotes thorough contact and blending of reactants, ensuring a uniform chemical reaction process.
Prevention of Solids Settling: Inhibits the deposition of solid particles—such as gypsum—at the bottom of the tank, thereby preventing sediment buildup and scaling.

3:Maintenance of Medium Homogeneity: Ensures consistent temperature, concentration, and solids distribution throughout the entire tank, stabilizing crystallization conditions and product quality.

Application:
Agitation of WPA slurry, mixing of reacting components, prevention of sedimentation, maintaining of homogeneous medium

Product Introduction

This heavy‑duty top‑entry agitator is custom‑engineered for harsh wet‑process phosphoric acid (WPA) slurry service, matched for 5700×5700×6770 flat‑bottom square tank. Its core functions include agitation of WPA slurry, homogenization of reacting components, prevention of solid sedimentation and maintenance of uniform medium throughout the tank, to secure stable phosphoric‑acid production.

Wetted parts adopt super duplex stainless steel to resist high temperature, severe corrosion and particle abrasion. Designed for heavy torque and high bending load, the unit supports long‑term continuous heavy‑duty operation.

Main Functions

Intense agitation for WPA slurry to eliminate low‑flow dead zones inside tank
Homogenize reacting components to guarantee uniform chemical reaction
Prevent gypsum and solid particles from settling at tank bottom
Maintain homogeneous temperature, concentration and solid distribution for stable crystal performance and product quality

Design Highlights

Heavy‑duty drive package: SUMITOMO heavy‑load reducer plus WEG industrial motor, excellent shock‑resistance for 24/7 continuous chemical serviceSumitomo D....
Corrosion‑resistant duplex steel: Wetted components in 2507 &1.4507 super duplex stainless steel, resisting WPA corrosion and gypsum particle erosion.
Dual‑impeller hydraulic design: Upper impeller homogenizes upper‑zone slurry; lower impeller disturbs tank bottom to avoid sediment accumulation. Bottom impeller is key‑connected and detachable for convenient on‑site replacement.
Reliable liquid shaft seal, minimizing leakage risk for hot corrosive slurry.
Rigid one‑piece mounting base (2250×1750 mm) absorbs huge static & dynamic loads, suppresses vibration and ensures stable shaft‑system performance.

Application

Primarily applied in WPA digestion / reaction tanks of phosphoric‑acid plant for phosphoric‑acid‑gypsum slurry mixing. Also suitable for other corrosive high‑solid‑content chemical processes requiring anti‑sedimentation and homogenization.
