Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a factory spanning 10,000–30,000 square meters, proudly presents our 304 Stainless Steel Mixed Salt Triple-Effect Evaporation System with PLC Control. Designed for a capacity of 5000 L/h, this system efficiently concentrates mixed salt solutions, significantly reducing waste volume and recovery costs. Built with high-grade stainless steel and advanced PLC automation, it ensures reliable operation, minimal maintenance, and consistent performance in demanding industrial environments.
Our triple-effect evaporation technology maximizes energy efficiency by reusing vapor from one effect as heating medium for the next. The PLC control system provides precise monitoring and adjustment of parameters such as temperature, pressure, and flow rate, enabling unattended operation and rapid response to process variations. This system is ideal for industries like chemical processing, pharmaceuticals, food & beverage, and wastewater treatment where mixed salt streams need to be concentrated or recovered.
Key Features and Technical Specifications
- Material of Construction: All wetted parts are made of 304 stainless steel, offering excellent corrosion resistance against salt solutions and easy cleaning.
- Evaporation Capacity: 5000 L/h (customizable from 1000 L/h to 20,000 L/h upon request).
- Number of Effects: Triple-effect design for high thermal efficiency, reducing steam consumption by up to 60% compared to single-effect systems.
- Control System: PLC (Programmable Logic Controller) with HMI touchscreen for real-time monitoring, automatic start/stop, alarm management, and data logging.
- Operation Mode: Continuous or batch mode selectable via PLC.
- Heating Source: Steam (saturated or superheated), hot water, or thermal oil – available as optional configurations.
- Evaporator Type: Falling film or forced circulation (depending on salt concentration and scaling tendency).
- Separator: High-efficiency vapor-liquid separator to minimize entrainment.
- Condenser: Shell-and-tube or plate type, with cooling water or air cooling options.
- Accessories: CIP cleaning system, concentrate discharge pump, vacuum system, and safety valves.

- Corrosion Resistance: 304 stainless steel construction ensures long service life even with aggressive salt solutions.
- Scalability: Modular design allows easy capacity expansion or integration with existing processes.
- Low Maintenance: Self-cleaning CIP system and anti-scaling design reduce downtime and manual cleaning effort.
- Flexibility: Handles various mixed salt concentrations (up to saturation) and can be adjusted for different feed compositions.
Frequently Asked Questions
-
Q: What is the maximum salt concentration this system can handle?
A: The system can handle feed solutions with total dissolved solids (TDS) up to 25% (250,000 ppm). For higher concentrations, forced circulation or special design may be required – please consult our engineers. -
Q: Can the PLC control system be integrated with our existing SCADA?
A: Yes, the PLC supports standard communication protocols like Modbus TCP/IP, Profibus, and OPC, allowing easy integration with most SCADA systems. -
Q: What is the typical delivery time?
A: Standard lead time is 45–60 days after order confirmation, depending on customization and factory workload. -
Q: Do you provide installation and commissioning services?
A: Yes, we offer on-site installation supervision and commissioning by our experienced engineers. Training for operators is also included. -
Q: Is the system suitable for treating wastewater with high scaling potential?
A: Our forced circulation version with anti-scaling design is recommended for such applications. We can also add online dosing of scale inhibitors. -
Q: What is the warranty period?
A: We provide a standard 12-month warranty from the date of shipment, covering manufacturing defects. Extended warranty options are available. -
Q: Can the capacity be adjusted for lower or higher flow rates?
A: Yes, the system is designed with a turn-down ratio of 3:1, allowing operation from 1667 L/h to 5000 L/h with stable performance. For capacities outside this range, we can customize the design. -
Q: Do you offer spare parts packages?
A: Yes, we recommend a starter spare parts kit including seals, gaskets, and sensors. A detailed list will be provided with the quotation.
