Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. As a leading manufacturer established in 2015 with a factory spanning 10,000–30,000 square meters and a team of 201–300 experienced professionals, we are proud to introduce our 3 Ton/H Evaporative Crystallization Unit. This advanced system is engineered with PLC control and constructed from 316L stainless steel, delivering exceptional durability and corrosion resistance. Our unit is designed to achieve low energy consumption while maintaining high efficiency, making it an ideal solution for industries requiring reliable crystallization of liquid streams. With over US$10 million in annual export value and serving markets across North America, South America, Europe, Asia, Africa, and Oceania, we bring global expertise to your facility.
The 3 Ton/H Evaporative Crystallization Unit is a complete system that integrates evaporation and crystallization processes into a single, compact footprint. It is specifically designed for industrial wastewater treatment, chemical processing, and zero liquid discharge (ZLD) applications. The unit utilizes forced circulation evaporation technology combined with a crystallization chamber to separate solids from liquids efficiently. The PLC control system ensures precise automation of temperature, pressure, feed rate, and discharge cycles, minimizing manual intervention and maximizing operational reliability.

Product Features & Benefits
- Low Energy Consumption: Our advanced heat pump integration and multi-effect design reduce energy usage by up to 30% compared to conventional evaporators. This translates to significant cost savings on your utility bills.
- 316L Stainless Steel Construction: All components in contact with process fluids are made of 316L SS, offering excellent resistance to corrosion from chlorides, acids, and other aggressive chemicals. This ensures a long service life and minimal maintenance.
- PLC Automation: The system is fully automated with a user-friendly HMI that allows operators to set parameters, monitor real-time data, and receive alarms. The PLC can also be integrated with your existing SCADA system for centralized control.
- High Crystallization Efficiency: The forced circulation loop and optimized crystallizer geometry ensure uniform crystal growth and high solid recovery rates. Typical recovery exceeds 95% for most salts.
- Compact Design: The unit is skid-mounted and pre-piped, reducing installation time and footprint. It can be easily transported and installed on-site with minimal civil works.
- Versatile Applications: Suitable for treating industrial wastewater from chemical, pharmaceutical, food processing, and mining industries, as well as producing high-purity crystals for reuse or disposal.
- Easy Maintenance: The design includes quick-opening doors and easy access to all key components. The 316L surface is smooth and easy to clean, reducing downtime for maintenance.
- Customizable Options: We offer various configurations including vacuum operation, heat recovery, and anti-scaling coatings to match your specific process requirements.
Technical Advantages
The 3 Ton/H Evaporative Crystallization Unit incorporates several engineering innovations:
- Forced Circulation Evaporator: Uses a high-flow pump to circulate the liquid through heat exchangers, preventing fouling and scaling. This ensures stable operation even with high solids concentration.
- Integrated Crystallizer: The draft tube baffle (DTB) crystallizer design promotes large, uniform crystals that are easy to centrifuge and dry.
- Automatic Discharge System: The PLC controls a pneumatic or motorized valve to periodically discharge crystal slurry, maintaining optimum slurry density.
- Vacuum Generation (optional): When equipped with a vacuum pump, the unit can operate at lower temperatures to handle heat-sensitive materials.
- Energy Recovery System: An optional mechanical vapor recompression (MVR) module can further reduce energy consumption to as low as 30 kWh/ton.
