Product Description
Energy Efficient Multiple Effect Evaporation System
Hanpu's Multiple Effect Evaporation (MEE) system delivers exceptional steam economy, stable production performance, and consistent product quality for chemical brines, effluent treatment, and salt/alkali applications. By cascading effects under vacuum conditions, secondary vapor from one effect efficiently heats the next, significantly reducing fresh-steam requirements and total operating expenses.
Superior Steam Economy & Low Operating Costs
3-5 effects efficiently reuse latent heat across multiple stages, reducing typical steam consumption to approximately 30-40% of single-effect units. Optional Thermal Vapor Recompression (TVR) and Mechanical Vapor Recompression (MVR) modules provide additional energy savings.
Gentle Processing & Reliable Operation
Vacuum operation and short residence times protect heat-sensitive materials. Mirror-polished tubes minimize scaling and simplify clean-in-place (CIP) procedures.
Advanced Automation & Process Consistency
PLC/HMI control with recipe management, data historian, and safety interlocks (vacuum/level/temperature). Optional inline density and conductivity monitoring ensures precise endpoint control.
Energy-Saving Cascade Process Operation
- Feed & Preheat: Metered feed enters the preheater and first-effect heater
- Effect 1: Live steam heats the first effect; generated vapor becomes heating medium for Effect 2
- Effects 2-N: Each subsequent effect operates at lower pressure/temperature, utilizing previous effect's vapor for boiling
- Condensation & Recovery: Final vapors condense in the condenser; clean condensate can be reused
- Crystallization (Optional): Concentrated liquor flashes or routes to vacuum crystallizer for salt recovery
System Configuration
Complete system includes effects (heaters & separators), preheaters, condenser & vacuum system, feed/circulation/discharge/condensate pumps, optional crystallizer & centrifuge, CIP skid, and comprehensive instrumentation (temperature/pressure/level/flow/vacuum/conductivity).
