Product Description
MVR evaporator (mechanical vapor recompression) is an advanced technology that reutilizes the energy from its own secondary steam, thereby significantly reducing the reliance on external energy sources. This technology was successfully implemented in Germany and France as early as the 1960s across various industries including chemical, pharmaceutical, paper, wastewater treatment, and seawater desalination. The operational principle involves compressing low-temperature steam using a compressor to increase its temperature and pressure, thus enhancing its enthalpy. The compressed steam is then condensed in a heat exchanger to fully utilize its latent heat. Apart from the initial startup phase, only a minimal amount of fresh steam is required throughout the entire evaporation process. In contrast to multi-effect evaporation, where secondary steam from one effect cannot be directly used as the primary heat source without additional energy input, MVR evaporators can compress all secondary steam generated within the system.
The solution circulates through a falling film evaporator via a material circulation pump within the heating tubes. Fresh steam outside the tubes heats the initial steam, causing the solution to heat up and boil, generating secondary steam which is then drawn into the turbocharger fan. After being supercharged, the secondary steam's temperature increases, allowing it to enter the heating chamber as a heating source for continuous circulation and evaporation. Once normal operation commences, the turbine compressor continuously draws in and supercharges the secondary steam, converting it into heated steam for ongoing circulation and evaporation. The resulting condensed water is eventually discharged.

Main principle:
Mechanical vapor recompression (MVR) evaporator utilizes the secondary steam generated in the evaporator, which is compressed by a compressor to increase pressure, temperature, and enthalpy. It is then sent to the heating chamber of the evaporator as heating steam, maintaining the boiling state of the feed liquid, while the heating steam itself condenses into water. In this way, the steam that was originally intended to be discarded is fully utilized, latent heat is recovered, and thermal efficiency is improved. The economy of steam production is equivalent to 20 effects of multi effect evaporation, reducing the demand for external heating and cooling resources, energy consumption, and pollution.
The MVR evaporator increases the energy of the secondary steam through the compressor and reuses it to heat the material, realizing the recycling of steam heat energy.
The specific process is as follows:
1. Evaporation process: The material is heated and evaporated inside the evaporator, and the generated steam is compressed by the compressor, and the pressure and temperature increase.
2. Steam compression: The high-pressure steam enters the evaporator again through the compressor as a heat source to continue heating the material.
3. Condensation separation: The mixture of evaporated steam and material is separated by the gas-liquid separator, the steam returns to the compressor, and the material is collected.
Structural composition The MVR evaporator is mainly composed of the following parts:
1. Evaporator body: It is the place where the material is concentrated. It is usually composed of a shell and tube heat exchanger to increase the heat transfer area.
2. Compressor: Compress the secondary steam to increase its energy for reheating the material.
3. Gas-liquid separator: Separate the steam from the concentrated liquid to ensure efficient operation.
4. Control system: Real-time monitoring and adjustment of temperature, pressure and other parameters to ensure that the equipment operates in the best state.
Advantages and application areas
MVR evaporator has the following advantages:
1. High efficiency and energy saving: By recovering steam heat energy and reducing the use of fresh steam, it can greatly save energy and reduce costs by 30%-80%.
2. High heat transfer efficiency: The tubular heat exchanger design increases the heat transfer area and improves the evaporation efficiency.
3. Wide range of applications: Suitable for evaporation and crystallization of various inorganic salts, evaporation of solutions with higher hardness, evaporation and concentration of garbage filtrate, and solution concentration in food, fermentation, pharmaceutical and other industries.
Operation precautions and maintenance
When operating the MVR evaporator, pay attention to the following points:
1. Temperature control: Ensure that the material temperature is within the appropriate range to avoid overheating or overcooling.
2. Pressure regulation: Keep the system pressure stable to ensure the steam compression effect.
