MVR stands for Mechanical Vapor Recovery. MVR is a technology that reuses the energy generated by its own secondary steam to reduce the demand for external energy. This technology is applied in industries such as chemical, pharmaceutical, papermaking, sewage treatment, and seawater desalination.
The working process involves the compression of low-temperature steam by a compressor, which increases the temperature and pressure, increases the enthalpy, and then enters a heat exchanger for condensation to fully utilize the latent heat of the steam. Except for starting the car, only a small amount of steam is required during the entire evaporation process.
In the process of multi effect evaporation, the secondary steam of one effect of the evaporator cannot be directly used as the heat source of the main effect, but can only be used as the heat source of the secondary effect or several secondary effects. As a heat source for this effect, additional energy must be provided to increase its temperature (pressure). The steam jet pump can only compress a portion of the secondary steam, while the MVR evaporator can compress all the secondary steam in the evaporator The solution is circulated in a falling film evaporator through a material circulation pump in the heating tube. The initial steam is heated by fresh steam outside the tube, which heats and boils the solution to produce secondary steam. The generated secondary steam is sucked in by a turbocharged fan, and after being pressurized, the temperature of the secondary steam increases and enters the heating chamber as a heating source for circulating evaporation. After normal start-up, the turbo compressor sucks in secondary steam, which is then pressurized and converted into heated steam. This continuously circulates and evaporates, and the evaporated water is eventually discharged as condensed water.

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.
