MVR evaporation crystallization equipment is low-carbon and environmentally friendly, with materials that can be recycled, high thermal efficiency, low energy consumption, and energy savings, greatly reducing operating costs; Small temperature difference, less prone to scaling and corrosion, and extended equipment service life.
1、 Working principle:
The MVR evaporation crystallization equipment uses a compressor to increase the energy of the secondary steam, and utilizes the increased energy of the secondary steam to recover the latent heat of the secondary steam. Specifically, the secondary steam generated by the evaporator is adiabatically compressed by a compressor to increase its pressure and temperature, and then sent as heating steam into the heating chamber of the evaporator for condensation and heat release. Therefore, the latent heat of the steam is recovered and utilized. Before entering the evaporator, the cold material absorbs the heat of the condensed water through a heat exchanger, causing its temperature to rise, while also cooling the condensate and completion liquid, further improving the utilization rate of heat.
Widely used for the evaporation, concentration, and crystallization of water or solutions in industries such as medicine, food, chemical, and light industry, and can be widely used for wastewater treatment in these industries.

2、 Customize suitable MVR evaporation crystallization equipment based on the specific parameters of sewage or wastewater provided by the user:
1. Preheater: In most cases, the solution to be evaporated must be heated before entering the evaporator.
2. Heater: The solution that needs to be evaporated exchanges heat with the heat source steam in the evaporator, resulting in evaporation. Select different types of evaporators based on the properties of different solutions.
3. Separators: Used for separating steam and liquid, different separators can be selected according to the properties of different solutions, generally including centrifugal separators, gravity separators, or separators with special structures.
4. Its empty system: maintains the vacuum degree of the entire system, extracts some air, non condensable gases, and gases brought in by the solution from the device to achieve a stable evaporation state of the system.
5. Pump: Transport the solution to be evaporated and the concentrated solution. According to the different properties of the solution, different types of pumps can be selected, generally including centrifugal pumps, volumetric pumps, and screw pumps.
6. MVR compressor system: By compressing the secondary steam to provide an evaporative heat source, it improves the heat dissipation of the secondary steam. According to the requirements of different flow rates and compression ratios, multiple compressors can be selected. For situations where the pressure rise is increased, multi-stage compressors can be used in series.
7. Control system: The MVR evaporation system control center adjusts the motor speed, valves, flow meters, temperature, and pressure to achieve automatic evaporation, cleaning, shutdown, and other operations. Automatic alarm, automatic protection system from damage, maintaining dynamic balance of the system.
8. Cleaning system: After evaporating different solutions for a period of time, scaling may occur. Generally speaking, more than 99% of scaling can be removed by adding chemical solvents, and CIP in-situ cleaning or dismantling cleaning can be used.
