MVR tubular forced circulation evaporation complete set equipment

Working principle 

1. MVR falling film evaporation (high-speed pre-concentration)

Ammonium sulfate solution flows in a thin film along the tube wall inside the falling film evaporator. It features a fast evaporation rate and a high heat transfer coefficient, making it highly suitable for dehydration in the early stage with large evaporation volumes.

2. MVR Forced circulation Evaporation (Crystallization Section)

The pre-concentrated high-salt solution enters the forced circulation section of the MVR and is driven by the circulation pump to flow at high speed, maintaining stable heat exchange efficiency while preventing the deposition of ammonium sulfate crystals and pipeline blockage.

3. Crystallization and discharge

The material gradually thickens in the system and is automatically and stably discharged after reaching the crystallization point. It can be seamlessly connected with centrifuges, filters or crystallizers.

The dual MVR process maximizes the utilization of latent heat of secondary steam, achieving extremely low energy consumption operation.

Product Overview

The MVR falling film + MVR forced circulation evaporation system is a highly efficient and energy-saving evaporation device specially designed for the crystallization treatment of ammonium sulfate solution. With an evaporation capacity of 20 tons per hour, it is suitable for the large-flow continuous concentration and crystallization conditions of ammonium sulfate solution.

The system adopts a "dual MVR structure" :

MVR falling film section → Achieve rapid and high-flow dehydration

MVR forced circulation section → Stabilize the crystallization condition and reduce the risk of scaling

All parts in contact with materials are made of 316L stainless steel, which is corrosion-resistant and has a long service life. It is suitable for the long-term operation requirements of the fertilizer, fine chemical and salt resource utilization industries.
