Working Principle:
Temperature & Heat Exchange: The evaporation temperature is set between
The vapor compressor creates a vacuum and compresses the vapor to generate high-temperature steam. This steam passes through the primary heat exchanger to heat the wastewater inside the boiling chamber. Concurrently, heat exchange occurs within the primary and auxiliary heat exchangers, condensing the steam into distilled water for discharge.Vapor Recompression: The secondary vapor generated from the evaporator is routed through vapor piping to the vapor compressor. The compressor recompresses the secondary vapor, increasing its pressure, temperature, and enthalpy (a process where electrical energy is converted into thermal energy).
IEnergy Recycling & Efficiency: At start-up, a small amount of live steam is introduced to heat the process liquid. The resulting vapor is separated, and a portion of it condenses into water. Non-condensable gases are then compressed by the vapor compressor into high-pressure, high-temperature steam, which is re-introduced into the evaporator to vaporize more liquid during gas-liquid separation. This process recycles the otherwise wasted secondary vapor, utilizing its latent heat to achieve maximum energy savings.

Evaporation Technology for Industrial Wastewater Volume Reduction:
During machining and metalworking, various impurities contaminate the cutting fluid—including metal ions from tool wear, metal debris from workpieces, waste oil, rust inhibitors, dust, and lathe lubricants. Combined with the high temperatures generated during machining, these chemically active metal impurities degrade the cutting fluid, compromising its stability and usability.
Our evaporation and concentration technology applies heat to vaporize the liquid portion and then condenses it back into a liquid state, achieving definitive solid-liquid separation. Since industrial wastewater typically contains a high percentage of water, separating the water via evaporation drastically reduces the volume of hazardous waste, minimizing downstream disposal burdens while concentrating the remaining waste for potential resource recovery.
Industrial Wastewater Evaporation, Reduction, and Resource Recovery Equipment:
The core of this evaporation technology lies in its integration with a heat pump system featuring multi-fold heating capabilities—meaning a single unit of electricity generates multiple units of thermal energy. By utilizing a vacuum pump to lower the system pressure, the boiling point is reduced, allowing wastewater to evaporate and condense under low power consumption to achieve massive volume reduction.
The distilled water recovered from evaporation can be treated and recycled back into production lines, achieving Zero Liquid Discharge (ZLD) within the facility. This vacuum evaporation and condensation technology significantly reduces hazardous waste disposal fees for manufacturers, striking an ideal balance between environmental compliance and economic viability.
Featuring low-carbon, energy-saving, and highly economical operations, this equipment is used not only for waste cutting fluids but also extensively across textile dyeing, electroplating, high-salinity streams, power plants, chemical plants, steel mills, coking facilities, and traditional Chinese medicine concentration.

Significant Waste Reduction and Production Cost Savings for Factories
Previously, manufacturing plants directly outsourced hazardous wastewater to third-party waste management firms, incurring high disposal fees. Today, implementing our wastewater evaporation and reduction equipment allows factories to drastically minimize waste volumes while recovering, concentrating, and refining process fluids. This significantly cuts operational overhead and effectively reduces outsourced waste disposal expenditures.
