MVR falling film tube evaporation complete set equipment

Working principle

The system is composed of a falling film evaporation section and an MVR forced circulation section.

1.Two-effect falling film evaporation (high-efficiency pre-concentration)

Sodium sulfate solution forms a uniform liquid film along the tube wall and evaporates rapidly, featuring high heat transfer efficiency and low energy consumption, enabling rapid dehydration at large flow rates.

2. MVR forced circulation Evaporation (Deep concentration of high-salt materials)

The high-salt solution enters the forced circulation section of the MVR and flows at high speed through the circulation pump to prevent scaling and ensure stable heat exchange.The secondary steam is compressed by MVR and reused, significantly reducing the demand for steam.

3. Continuous and stable concentration

Through the combination of two-effect and MVR, the material concentration can be precisely controlled at 28%, making it suitable for continuous industrial operation scenarios.

Product Overview

This Dual-Effect Falling Film + MVR Forced Circulation Evaporation System is specifically designed for large-scale continuous evaporation and the processing of high-salinity materials. Boasting exceptional evaporative capacity, it can reliably concentrate sodium sulfate solutions to a concentration of 28%.

The system integrates the highly efficient heat transfer capabilities of dual-effect falling film evaporation with the robust processing stability of MVR forced circulation evaporation—particularly regarding high-salinity feeds—thereby achieving exceptionally high evaporation efficiency, remarkably low energy consumption, and superior adaptability.

All critical components in contact with the process fluid are fabricated from 316L stainless steel. These components feature excellent resistance to corrosion, salt crystallization, and scaling, thereby ensuring the long-term, stable operation of the equipment and meeting the demands of high-load, continuous production within the chemical industry.
