Working principle

The system consists of a three-effect evaporation section and an MVR compression section:
Three-effect plate evaporation
The materials enter the first-effect, second-effect and third-effect evaporators in sequence, and are heated step by step by secondary steam, achieving the stepwise utilization of thermal energy.
MVR vapor recompression
The secondary steam generated in the final effect is heated and pressurized by the MVR compressor and then returned to the previous effect as heating steam, thus forming a closed thermal cycle.
Continuous concentration output
The material circulates and evaporates within the system, with its concentration gradually increasing. After reaching the set concentration, it is stably discharged.
This combination significantly reduces the demand for external steam supply and achieves efficient and energy-saving operation.

Product Overview

The MVR three-effect plate evaporation system adopts a deep coupling design of mechanical vapor recompression (MVR) and three-effect evaporation, combined with an efficient plate heat exchange structure, to achieve continuous concentration production with a stable evaporation capacity of 18 tons per hour.

The system is specially optimized for the working conditions of highly corrosive and highly alkaline materials such as sodium hydroxide solution concentration. It can concentrate the materials to the target range of 21.7% under low energy consumption conditions while maintaining long-term stable operation.

All parts in contact with materials are made of 316L stainless steel, which has excellent alkali resistance and corrosion resistance, and is suitable for long-term continuous production scenarios in the chemical industry.

FAQ

What materials is this MVR three-effect evaporation system suitable for?
+

It is applicable to corrosive materials such as sodium hydroxide, inorganic alkali solutions, chemical mother liquor, and high-salt/high-alkali waste liquid.
What is the evaporation capacity of this equipment? Can it be customized?
+

The standard evaporation capacity is 18 tons per hour. We can provide customized solutions ranging from 10 to 60 tons per hour or more according to your requirements.
Why is the system equipped with MVR? What are the advantages?
+

MVR can recover the thermal energy of secondary steam, significantly reducing steam consumption. Energy savings can reach 70% to 90%, greatly lowering operating costs.
What is the material? Can it withstand strong alkali?
+

All parts in contact with materials are made of 316L stainless steel, which has excellent corrosion resistance to strong alkaline materials such as NaOH.
Is the system running stably? Is it prone to scaling?
+

The plate heat exchanger structure and the optimized circulation design effectively reduce scaling and are suitable for 24/7 continuous operation.
