MVR is the abbreviation for mechanical vapor recompression technology. MVR is an energy-saving technology that reuses the energy of the secondary steam it generates, thereby reducing the need for external energy sources. As early as the 1960s, Germany and France had successfully applied this technology in fields such as chemicals, food, papermaking, pharmaceuticals, seawater desalination, and wastewater treatment. Introduction to the MVR high-efficiency energy-saving evaporation system: 1. Preheater: In many cases, the liquid to be evaporated has a low temperature before entering the evaporation heat exchanger; in order to make full use of the thermal energy available in the system, tubular or plate heat exchangers are often used to preheat this liquid. 2. Steam compressor: It is the core component of the MVR system. By compressing the secondary steam, it increases its enthalpy, thereby providing a continuous supply of steam to the system. Based on characteristics such as the flow rate of the stock solution and the boiling point elevation, a Roots or centrifugal compressor can be selected. For stock solutions with a large boiling point elevation, compressors can be used in multiple stages in series. 3. Vapor-liquid separator: It is a device used to separate steam from the concentrated liquid. For the mother liquor containing crystals, the separator and crystallizer can be designed as one unit, to which a forced circulation pump is added to carry out the functions of vapor-liquid separation, concentration, and crystallization. 4. Steam heat exchanger: The preheated source fluid is fed into the steam heat exchanger via a feed pump, where it exchanges heat with the steam generated by the steam compressor, resulting in its rapid vaporization. The type of heat exchanger is selected based on the properties of the stock solution (viscosity, presence of crystals and scaling, etc.). 5. Control Center: An MVR series real-time monitoring center is constructed using industrial computers and PLCs. Through software programming, the status signals from various sensors are collected in real time, thereby enabling automatic control of the motor’s speed, valve closure and adjustment, the flow rate and volume of liquids, as well as temperature and pressure control, so that the system operates in a state of dynamic equilibrium. At the same time, this device also has various functions such as automatic alarm, automatic parameter recording, and report generation. Energy-saving principle: Electricity is used to generate heat energy, which is then recycled within the system with almost no losses. The heat energy from the distilled water and concentrated solutions is exchanged with that of the original solution.

The wet-bulb temperature represents the lowest temperature that can be achieved through cooling in a cooling tower. However, there is a significant difference between 32° and 27°; therefore, if it is desired to lower the temperature even further, it is recommended that your cooling tower be larger. . .
