Product Description


Mechanical Vapor Recompression Mvr Evaporator System
Mechanical Vapor Recompression Mvr Evaporator, is a steam recompression technology that utilizes the energy from the secondary steam it generates to reduce the demand for external energy, making it an energy-saving technology. The process employs a mechanical compressor (or fan) to recompress the secondary steam produced after evaporation, thereby increasing its enthalpy. The increased enthalpy of the secondary steam is then used as a heat source in the heating chamber to heat the feed material. As it releases heat, the steam undergoes a phase change into condensate water, which is then expelled from the system. The heated material is concentrated through vaporization and is discharged from the system as the final product.
WTEYA pursues digital and intelligent manufacturing to provide customers with excellent products and services. We not only provide a series of standardized products that have been rigorously tested and have stable performance to meet a wide range of industry needs. We also provide customized services, and our professional design team provides customers with tailor-made solutions to meet their unique needs. We will work closely with each customer to ensure that each piece of equipment can accurately meet the customer's process requirements and production processes. WTEYA provides a full range of services, creates high-quality mechanical products and system solutions with ingenuity, and professionally helps customers deal with various water treatment problems.

Product Composition
The Mechanical Vapor Recompression MVR evaporation system is comprised of an evaporator, separator, compressor, vacuum pump, circulation pump, operating platform, electrical instrument control cabinet, as well as components such as valves and pipelines.

Technical principle
Mechanical Vapor Recompression (MVR) evaporation technology operates on the principle of using a mechanical compressor (or fan) to recompress the secondary steam produced after evaporation, thereby increasing its enthalpy. The enhanced enthalpy secondary steam is then reused as a heat source in the heating chamber to heat the feed material. As it releases heat, the steam undergoes a phase transition into condensate water, which is subsequently discharged from the system. The heated material is concentrated through vaporization and is expelled from the system as the final product.

Product Parameters


Evaporation Process: 
A. Feed Process:The feed is pumped to a plate heat exchanger by a feed pump to exchange heat with the condensate water produced by the MVR evaporator.After heat exchange, the material enters the MVR plate forced-circulation evaporator to exchange heat with the secondary steam compressed by the compressor. The heat-exchanged liquid is then pumped into a separator and begins to evaporate in a forced-circulation mode at an evaporation temperature of 90°C. 
B. Evaporation Process:When the material reaches the evaporation temperature and starts to evaporate, the generated steam and entrained tiny droplets rise in the separator. During this ascent, they pass through a demister, which ensures the separation of tiny droplets (≤1um) entrained in the secondary steam. This achieves an effective separation, reducing damage to the compressor caused by the material and improving the quality of the condensate water.The well-separated secondary steam is then compressed, raising its temperature by 20°C with a compression ratio of 2.04. The compressor provides a 20°C temperature increase.The solution entering the separator is circulated back into the evaporator by a circulation pump to exchange heat with the 110°C secondary steam. The secondary steam condenses into water and enters a condensate water tank. The material absorbs the heat from the steam and flash evaporates in the separator for gas-liquid separation. The concentrated liquid is pumped back to the evaporator by the circulation pump to continue evaporating until the desired concentration is reached, with the secondary steam temperature at 90°C and the concentrated liquid temperature not exceeding 104°C. 
C. Discharge Process:In this scheme, the discharge is entirely controlled by the PLC control system. Based on the company's experience from multiple projects, a recycling discharge system is designed.When the predetermined evaporation concentration is reached, the system controls the discharge. The concentrated solid-liquid mixture (salt sludge) is collected for further processing (the state of the concentrated material should be determined based on actual material trial experiments).Non-condensable gases are automatically vented through the control system. 
D. Drainage Process:The secondary steam condenses into water, enters a condensate water tank, and is then pumped by a condensate water pump to the preheater for heat exchange with the raw material. After heat exchange, it is drained into a distilled water storage tank.

Product Features/Advantages:
Mechanical Vapor Recompression Mvr Evaporator require only a minimal amount of live steam, significantly reducing operational costs and environmental pollution. With no waste heat steam emissions, the energy-saving effect is highly notable. The use of a compressor to provide heat means that compared to traditional evaporators, the temperature difference is much smaller, allowing for gentle evaporation, which greatly improves product quality and reduces scaling. The structure and process are very straightforward, with fully automatic operation, capable of continuous running, safe and reliable. The equipment is equipped with CIP (Cleaning in Place) cleaning pipelines, enabling on-site cleaning. The entire setup is user-friendly with no dead angles. The absence of waste heat steam emissions highlights the significant energy-saving benefits. Any materials suitable for single-effect and multi-effect evaporators can be processed using MVR evaporators, which are technically fully replaceable and offer superior environmental and energy-saving features.

Application Scope:
The Mechanical Vapor Recompression Mvr Evaporator technology is applicable across a wide range of industries due to its energy-efficient and environmentally friendly characteristics. It is particularly useful in situations where there is a need to recover or reduce the volume of solvents, extract valuable chemicals, or simply reduce wastewater output. The scope includes, but is not limited to: Industrial wastewater treatment: For general industrial processes that generate wastewater requiring treatment and volume reduction.
High-salinity wastewater: Treatment of waters with high salt content, which can be challenging and costly with traditional methods.
Landfill leachate treatment: Treatment of liquid effluent from landfill sites, which often contains a complex mixture of contaminants.
Electronics and semiconductor industry: Used for purification processes, cleaning operations, and other treatments where water quality is critical.
Lithium battery industry: In the production of lithium-ion batteries, MVR can be used to recover solvents and remove byproducts.
Coal chemical industry wastewater: Treatment of waste streams generated during the conversion of coal to various chemicals and fuels.
Textile dyeing wastewater: Used in the treatment of colored effluents from textile mills and dye houses.
Papermaking wastewater: Treatment of water used in the paper production process, which may contain suspended solids, organic materials, and other impurities.
Chemical industry: MVR can be applied in various chemical processes where solvent recovery or waste minimization is essential.
Food industry: Application in food processing plants for concentrating products, extracting ingredients, and treating waste streams.
Brewing industry: Used in beer and wine production for concentration and extraction processes.Dairy industry: Application in milk processing for concentration of milk and whey, as well as treatment of dairy effluents.
