Welcome: Yiwu Weihao Machinery Equipment Company
Yiwu Weihao Machinery Equipment Company professional evaporator manufacturer specializing in energy-saving industrial equipment, we design and produce high-performance MVR Forced Circulation Evaporators. This equipment combines the stable operation of forced circulation technology with the ultra-energy-saving advantage of MVR (Mechanical Vapor Recompression), solving the pain points of high energy consumption, high operation cost, and unstable operation in traditional evaporation processes, providing a high-efficiency, low-consumption, and environmentally friendly solution for various industrial liquid concentration and treatment projects.
Our MVR Forced Circulation Evaporator is a high-end energy-saving equipment integrating forced circulation evaporation and MVR technology, widely used in chemical, environmental protection, pharmaceutical, food, and other industries. Different from traditional forced circulation evaporators, it is equipped with a high-efficiency MVR compressor, which recompresses the secondary steam generated during evaporation into high-temperature, high-pressure steam, and reuses it as the heating source for the evaporator—greatly reducing the demand for external fresh steam and energy consumption. The forced circulation design ensures stable operation for high-viscosity, scaling-prone liquids, while the MVR system achieves ultra-low energy consumption, helping enterprises reduce operation costs and carbon emissions.
Feed Preparation: Raw liquid (industrial wastewater, chemical solution, food liquid, etc.) is pre-filtered to remove impurities, adjusted to appropriate viscosity and temperature to ensure smooth circulation.
Forced Circulation: The pre-treated liquid is pumped into the heating chamber by a high-pressure, anti-clogging circulation pump, forming a high-speed turbulent flow in the heating tubes—preventing material deposition, scaling, and blockage.
Evaporation & MVR Vapor Recompression: The liquid is heated by the recompressed steam in the heating tubes, and under vacuum conditions (-0.06 to -0.095 MPa), the water in the liquid boils and evaporates to generate secondary steam. The MVR compressor suctions and compresses the secondary steam, increasing its temperature and pressure to become high-quality heating steam, which is then recycled back to the heating chamber.
Vapor Condensation (Minimal): Due to the high reuse rate of secondary steam, only a small amount of non-condensable gas and residual vapor need to be condensed by the condenser, reducing water and energy consumption.
Concentration & Discharge: The liquid is continuously circulated and concentrated to the required concentration, then continuously discharged; the forced circulation ensures uniform concentration, and the MVR system maintains stable energy supply, realizing efficient and low-consumption operation.
Ultra Energy-Saving: MVR system recompresses and reuses secondary steam, reducing external steam consumption by 80–90% compared to traditional single-effect evaporators and 50–70% compared to multi-effect evaporators, significantly lowering operation costs.
Stable Forced Circulation: High-speed turbulent flow avoids scaling, deposition, and blockage, suitable for high-viscosity (up to 10,000 cP), scaling-prone, and crystal-containing liquids, ensuring long-term stable continuous operation.
Gentle & High-Quality Processing: Low-temperature operation (45–75°C) under vacuum, short residence time (2–8 seconds), effectively retaining nutrients (for food/pharmaceutical) and chemical stability (for chemical) of materials, avoiding thermal degradation.
Corrosion & Wear Resistance: Contact parts are made of high-grade corrosion-resistant materials (316L stainless steel, Hastelloy optional), resisting corrosion from acidic, alkaline, high-salt liquids, and wear from solid particles.
Environmentally Friendly: Minimal steam consumption reduces boiler emissions; low water consumption for condensation, complying with energy conservation and environmental protection standards; realizing resource reuse and zero liquid discharge (ZLD) optional.
Intelligent & Easy Operation: PLC + HMI automatic control system, real-time monitoring of temperature, pressure, vapor flow, and concentration; automatic adjustment of MVR compressor speed and circulation flow, realizing unmanned operation and easy maintenance.
