Heat Pump Low Temperature Concentration Equipment
Heat pump low-temperature distillation technology utilises a heat pump heating system to supply thermal energy to the distillation chamber while operating under negative pressure to lower the boiling point. This enables wastewater to evaporate and concentrate at low temperatures, preventing damage to water quality and raw materials while significantly improving energy efficiency.
Application Areas
-Treats MVR mother liquor, multi-effect evaporator concentrates, RO concentrate, high-salinity, electroplating, precious metal, cleaning, mining, chemical, pharmaceutical wastewater and more.
-Handles difficult-to-treat industrial wastewater, reducing disposal costs and minimizing waste while recovering resources, and ensuring safe treatment.
-Purifies and concentrates raw materials in chemical processes by precisely controlling evaporation, enhancing product purity and quality.
Key Advantages
-Based on industrial HVAC principles, heat pump technology provides reliable, stable performance while minimizing energy use.
-Saves significant energy compared with conventional evaporation or flocculation processes, reducing operating costs.
-Provides precise temperature and pressure control to ensure optimal distillation conditions and further improve energy efficiency.
-Evaporates water at low temperatures (~35°C), minimizing scaling and fouling. Achieves over 90% concentration, reducing off-site wastewater disposal costs.
-No chemical additives required, relies purely on the physical distillation process.
-Operates under fully enclosed negative pressure, preventing gas leakage, with vacuum levels up to –0.098 MPa.
-Highly automated, compact, easy to install and operate with minimal supervision.
-Runs on electricity and compressed air, no extra heat or cooling water needed.
-Produces stable, clear effluent that can be reused or discharged without further treatment.
-All parts in contact with wastewater are made of SS316L stainless steel, providing excellent corrosion resistance and thermal conductivity.
-Proven low-temperature distillation technology with wide applications, stable operation, and low failure rate.
-More convenient and user-friendly compared with MVR or traditional processes such as filter press or pressure filtration.
-Easy to maintain, with all parts readily available on the market and low upkeep costs.
-Uses PLC control with a touchscreen HMI for real-time monitoring, automatically alarming and shutting down in case of equipment faults or insufficient feed.
