As a leading manufacturer with nearly a decade of expertise in environmental and process technology, Qingdao Conqinphi Environmental Technology Group is proud to introduce our advanced Compact Four-Effect Evaporation Crystallizer Unit with Semi-Automatic Operation Mode. Engineered for efficiency and reliability, this system is designed to tackle complex concentration and crystallization challenges in industries ranging from chemical processing to zero-liquid discharge (ZLD) wastewater treatment. Our commitment to innovation and quality, backed by a robust 10,000-30,000 square meter manufacturing facility, ensures that every unit delivers superior performance, maximizing resource recovery and minimizing operational costs for our global clientele.
This integrated unit combines multiple evaporation effects into a compact footprint, significantly enhancing thermal efficiency and reducing energy consumption compared to single or double-effect systems. The semi-automatic operation mode provides an optimal balance between intelligent control and operator oversight, making it suitable for facilities seeking to upgrade their processes without requiring fully automated infrastructure.
Core Features & Technical Advantages:
- High Thermal Efficiency: Utilizes a four-effect design where vapor from one effect serves as the heating medium for the next, dramatically lowering steam consumption and operational energy costs.
- Compact & Modular Design: Engineered for space-saving installation, our unit is ideal for plants with limited floor space. The modular construction also allows for easier transportation and faster on-site assembly.
- Semi-Automatic Intelligent Control: Equipped with a user-friendly PLC and touch-screen HMI. The system automates critical processes like temperature, pressure, and level control, while allowing manual intervention for specific batch operations or parameter adjustments.
- Robust Construction & Corrosion Resistance: Primary components are constructed from high-grade stainless steel (316L or 304), ensuring long service life when handling aggressive chemicals, high-salinity brines, or food-grade materials.
- Versatile Application Scope: Capable of processing a wide range of feed streams to produce high-purity water and recover valuable salts or crystals.
Key Technical Specifications:
The following table outlines some standard parameters. All specifications can be customized to meet specific project requirements.
| Parameter | Description / Typical Range |
|---|---|
| Evaporation Effects | Four (4) Effects |
| Operation Mode | Semi-Automatic (PLC Controlled) |
| Heating Source | Saturated Steam, Thermal Oil, or Electric Heater |
| Design Pressure | Vacuum to Customizable Positive Pressure |
| Material of Construction (Wetted Parts) | SS304, SS316L, Duplex Steel, Titanium (Optional) |

Frequently Asked Questions (FAQ):
-
What is the main advantage of a four-effect design over a single-effect unit?
The primary advantage is dramatically improved energy efficiency. In a four-effect system, heat is reused across multiple stages, significantly reducing the amount of fresh steam or energy required per unit of water evaporated, which translates to lower operating costs. -
What does "semi-automatic operation" mean in practice?
It means the core evaporation and crystallization processes (like temperature control, pump sequencing, and safety interlocks) are managed automatically by a PLC. Operators can monitor the system via an HMI and manually initiate specific cycles, adjust setpoints, or handle feeding/discharge as needed for batch operations or flexibility. -
Can this unit handle corrosive or scaling feed solutions?
Yes. We offer construction materials like SS316L, duplex stainless steel, or titanium for highly corrosive streams. The design also incorporates features to mitigate scaling, and anti-scale chemical dosing systems can be integrated as an option. -
Is the capacity fixed, or can it be customized?
The capacity is fully customizable. We design and manufacture systems based on your specific feed flow rate, inlet concentration, and desired final product (concentrate or dry crystals), from small pilot plants to large industrial-scale units. -
What kind of after-sales support do you provide?
We provide comprehensive support including detailed operation manuals, installation guidance, remote troubleshooting assistance, and availability of spare parts. On-site commissioning and training services are also available upon request. -
How long is the delivery time for a standard unit?
Delivery time varies based on the complexity and capacity of the customized system. Generally, it ranges from 3 to 6 months after final design confirmation. We provide a projected timeline during the quotation process. -
Can the system be integrated with our existing plant utilities?
Absolutely. Our engineering team will review your available utilities (steam pressure, cooling water, electrical supply) during the design phase to ensure seamless integration with your current infrastructure. -
What is the typical end product form from this crystallizer?
The system can be configured to produce a concentrated slurry or a dry solid, depending on the downstream equipment (like a centrifuge or dryer) integrated with the evaporator. We design the complete solution to meet your final product specification.
