Working Principle and Applications
- Heat pump evaporation technology combines heat pump and vacuum applications, making it a widely used energy-saving treatment technology.
- The main components of the system include a refrigerant compressor, heat exchanger, vacuum pump, and other units. The concentrated waste liquid undergoes multiple cycles of concentration in the concentration tank before being stored in the concentrated liquid tank.
- The vacuum evaporation method automatically draws waste liquid into the concentration tank. Through the heater, it undergoes low-temperature boiling under reduced pressure, then condenses into water through the cooling system.
- Using the heat pump principle to heat waste liquid, the vacuum pump creates negative pressure to lower the boiling point and enhance evaporation efficiency. The chilled water system condenses the evaporated vapor to achieve volume reduction, and membrane filtration further filters the condensate for reuse.
- This process enables water recovery and reuse, significantly reducing the total discharge of waste liquid, lowering treatment costs, and conserving water resources through the reuse of filtered condensate.
Evaporation Steps and Equipment Features
- The vacuum pump extracts waste liquid into the evaporation tank.
- The vacuum pump draws waste liquid into the waste liquid heater.
- The water-sealed vacuum pump reduces the internal pressure of the concentration tank to a negative pressure.
- The concentration tank is heated to a low boiling temperature (42°C–60°C).
- Water vapor condenses into water in the condenser.
- After multiple evaporation cycles, the concentrated liquid reaches the set concentration and is discharged into a temporary storage tank.
- Equipped with a high-efficiency scroll refrigerant compressor and a powerful water-sealed vacuum pump, ensuring stable discharge of harmless water for zero pollution.
- Load cell and PLC human-machine precision control system for automated processing.
- The evaporation process is fully automated and continuously repeated through the control system.
- The cleaning system removes adhered impurities from the equipment.
- The low-temperature evaporation mode requires minimal space, operates at the lowest cost, and significantly reduces COD levels.
- The condensed water can be further filtered by membrane filtration equipment for reuse.
- Fully automated, stable water discharge, supporting "zero discharge" and environmentally friendly green solutions.
Evaporation Technology for Industrial Waste Liquid Concentration and Reduction
During machining processes, various impurities are generated, including metal ions from tool wear, metal chips, waste oil, rust inhibitors, dust, and lathe lubricants. The combination of high temperatures and chemically active metal impurities can degrade the cutting fluid, ultimately affecting its stability and usability. Evaporation concentration technology separates solids from liquids by heating the waste liquid into vapor and then condensing the vapor back into liquid. Since industrial waste liquids often contain a high percentage of water, removing this water through evaporation significantly reduces the volume of waste that requires further treatment. Additionally, the concentrated waste liquid can be recovered and reused.
Industrial Waste Liquid Evaporation, Concentration, Reduction, and Recycling Equipment
The key to evaporation technology is integrating a heat pump system, which provides multiple times the heating capacity per unit of electricity consumed. The vacuum pump creates negative pressure, lowering the evaporation temperature, allowing the system to evaporate and condense water with minimal power consumption. The evaporated water can then be treated and recycled back into the manufacturing process, achieving zero liquid discharge within the factory. By applying vacuum evaporation and condensation technology, industries can reduce waste treatment costs while meeting both environmental and economic goals. The evaporation equipment is characterized by its low carbon footprint, energy efficiency, environmental friendliness, and cost-effectiveness. Besides cutting fluid waste reduction, it is also used in treating industrial wastewater from dyeing and printing, electroplating, saline wastewater, power plants, chemical plants, steel mills, coking plants, and traditional Chinese medicine concentration processes.
Advantages of Low-Temperature Evaporation and Concentration
- Operates at low evaporation temperatures, minimizing scale formation and ensuring high-quality treated water.
- Fully automated system, requiring no manual operation.
- No need for flocculation before evaporation or biochemical treatment after evaporation, simplifying the wastewater treatment process.
- Requires only industrial electricity or auxiliary systems such as steam boilers.
- The low-temperature heat pump technology is based on industrial air conditioning principles, ensuring reliability and low maintenance costs.
Features of Low-Temperature Evaporation and Concentration
- Fully automated operation using low-temperature vacuum evaporation.
- Innovative vacuum evaporation technology ensures low operating costs.
- High-efficiency scroll-type refrigerant compressor.
- Utilizes a safe and powerful water-sealed vacuum pump to extract vapor.
- Automatically stabilizes discharged water quality, promoting zero discharge and green environmental protection.
Significant Reduction of Waste Liquid Discharge and Production Cost Efficiency
In the past, factories outsourced waste liquid disposal to waste treatment companies. Today, by adopting waste liquid evaporation and reduction equipment manufactured by Yuan-Chang, factories can significantly reduce waste liquid volume while recovering and reusing concentrated refined waste liquid. This leads to substantial cost savings and a reduction in outsourcing treatment expenses.
