Welcome: Yiwu Weihao Machinery Equipment Company
As a leading manufacturer of industrial evaporation and crystallization equipment, Yiwu Weihao Machinery Equipment Company specializes in designing and manufacturing high-efficiency Salt Crystallization MVR Evaporator Crystallizers, integrating MVR (Mechanical Vapor Recompression) evaporation technology and salt crystallization technology into one integrated system. This equipment is specially designed for industrial salt production, high-salt wastewater treatment, and salt resource recovery, realizing efficient concentration, crystallization, and solid-liquid separation of high-salt solutions with ultra-low energy consumption, which is the core equipment for energy-saving salt production and zero liquid discharge (ZLD) projects.
Compared with traditional multi-effect evaporator crystallizers, our MVR integrated system reduces energy consumption by 70-80%, greatly lowering the operating cost of salt production and high-salt wastewater treatment, and is widely used in seawater salt production, chemical salt purification, and high-salt wastewater resource recovery industries.
The Salt Crystallization MVR Evaporator Crystallizer realizes integrated operation of evaporation and crystallization through a scientific workflow, combining the energy-saving advantages of MVR with the high-efficiency of salt crystallization: 1. Feed Liquid Pretreatment: High-salt feed liquid (seawater, brine, high-salt wastewater) is pretreated to remove suspended solids, colloids, and impurities, avoiding scaling and blocking the equipment. 2. MVR Evaporation Concentration: The pretreated feed liquid enters the evaporator, where the secondary steam generated by evaporation is compressed by the MVR compressor to increase temperature and pressure, and then recycled as heating steam to heat the feed liquid, realizing energy reuse and reducing external energy input. 3. Salt Crystallization: As the feed liquid is continuously concentrated, the salt concentration reaches supersaturation, and crystals are formed in the crystallization chamber; the forced circulation system ensures uniform crystal growth and prevents scaling. 4. Crystal Separation & Discharge: The crystal slurry is separated by a separator, the large-grain salt crystals are discharged as finished products, and the mother liquor is recycled to the evaporator for further concentration and crystallization. 5. Tail Gas Treatment: The small amount of non-condensable gas is treated to meet environmental discharge standards, ensuring green and environmentally friendly operation.
Integrated Design: Combine MVR evaporation and salt crystallization into one unit, compact layout, small footprint, and reduced equipment investment.
Ultra Energy-Saving: MVR compressor recycles secondary steam, energy consumption is only 15-30% of traditional multi-effect evaporators, ton salt energy consumption is as low as 80-120 kWh.
High Crystallization Efficiency: Forced circulation system ensures uniform heating of feed liquid, avoids crystal agglomeration, and produces high-purity salt crystals (purity up to 99.5%+).
Strong Adaptability: Suitable for various high-salt solutions, including seawater, brine, chemical salt solution, and high-salt industrial wastewater; compatible with different salt types (sodium chloride, sodium sulfate, ammonium salt, etc.).
Stable & Anti-Scaling: Scientific pretreatment and forced circulation design prevent scaling and coking; all wetted parts are made of 316L stainless steel or duplex stainless steel, corrosion-resistant and long service life.
Fully Automatic Control: PLC + touch screen control system, real-time monitoring of temperature, pressure, liquid level, and crystal particle size, realizing unmanned operation and easy maintenance.
Customizable Design: According to customer’s feed liquid properties, salt type, production capacity (ton/day to 1000 tons/day), and site conditions, customize the system configuration, evaporation area, and crystallization chamber size; support skid-mounted or integrated installation.
