summary:

The abbreviation for MVR evaporator. MVR is a technology that reuses the energy generated by its own secondary steam to reduce the demand for external energy.

The secondary steam, after being compressed by the compressor, increases in pressure and temperature, and increases in enthalpy. It is sent to the heating chamber of the evaporator as heating steam, which is used to maintain the evaporation state of the material liquid. The heating steam itself transfers heat to the material and condenses into water. In this way, the steam that was originally intended to be discarded is fully utilized, latent heat is recovered, and efficiency is improved.
As early as the 1960s, Germany and France had successfully applied this technology to 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, there is no need to generate steam 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, thus continuously circulating and evaporating. The evaporated water eventually becomes condensed water and is discharged.

Application:
This equipment is suitable for industries such as pharmaceuticals, biology, food, and chemical engineering. It is commonly used for evaporation and concentration of traditional Chinese medicine extracts, fruit juices, fine chemical solutions, wastewater, and other materials.

Features:
1. Adopting MVR heat pump evaporation structure, normal evaporation operation can be carried out with minimal steam preheating of the liquid. The energy-saving effect is significant. The electricity consumption is 30-50 kWh/1000kg of water.
2. The equipment mainly consists of a heat exchanger, separator, defoamer, booster pump, etc.
3. Adopting vacuum pressure reduction operation, the evaporation temperature is low and the speed is fast, and the configuration of each instrument valve is reasonable and convenient for operation.
This is currently an energy-efficient product.
