As a leading manufacturer specializing in advanced separation and environmental solutions, Qingdao Conqinphi Environmental Technology Group is proud to offer our high-efficiency Four-Effect Forced Circulation Evaporation Crystallization Equipment. With a robust processing capacity of 10 tons per day, this system is engineered to tackle the most demanding concentration and crystallization challenges in industrial applications, from zero-liquid discharge (ZLD) wastewater projects to high-purity chemical recovery. Our decade of experience since 2015, backed by a comprehensive quality management system, ensures that every unit delivers reliable performance, significant energy savings, and a rapid return on investment for our global clientele.
This sophisticated evaporation system is designed to maximize thermal efficiency and operational stability. The core of its performance lies in the forced circulation design combined with a four-effect configuration. Unlike natural circulation evaporators, a pump actively circulates the process fluid at high velocity through the heat exchanger tubes. This is particularly advantageous for feeds prone to fouling, scaling, or with high viscosity, as it minimizes deposit formation on heat transfer surfaces and maintains consistent evaporation rates. The multi-effect setup cascades the vapor from one effect to serve as the heating medium for the next, dramatically reducing steam consumption. Typically, a four-effect system can achieve a steam economy where one kilogram of primary steam evaporates approximately 3 to 3.5 kilograms of water, representing a substantial reduction in operational energy costs.
The equipment is constructed with durability and corrosion resistance in mind. Critical wetted parts, such as the heat exchangers, separator bodies, and circulation lines, are typically fabricated from high-grade 316L stainless steel or other alloys suitable for specific corrosive process streams. The system's modular design allows for flexibility in layout and future expansion. Key operational parameters are monitored and controlled through an advanced automation system, which can be configured to include:
- PLC-based Control Panel: For centralized operation, data logging, and alarm management.
- Variable Frequency Drives (VFDs): On circulation and feed pumps for precise flow control and energy savings.
- Online Instrumentation: Including density, pH, temperature, and pressure sensors for real-time process optimization.
- Optional CIP (Cleaning-in-Place) System: To reduce downtime for maintenance.
Below is a summary of the primary technical specifications for the standard 10 T/D model:
| Parameter | Specification |
| Design Capacity (Evaporation) | 10 tons of water per day |
| Number of Effects | 4 |
| Circulation Type | Forced Circulation |
| Primary Heating Medium | Saturated Steam |
| Operating Pressure Range | Vacuum to Slightly Positive (customizable) |
| Final Product Output | Concentrated liquor or solid crystals (via integrated crystallizer) |
| Main Material of Construction | 316L SS / Other alloys available |
| Control Level | Semi-Automatic / Fully Automatic (optional) |
The benefits of choosing this system extend far beyond its basic specifications. For plant managers and project engineers, it translates into tangible operational advantages:
- High Thermal Efficiency: The multi-effect design drastically cuts steam requirements, lowering your utility bills.
- Robust Handling Capability: Ideal for difficult feeds that would foul or clog other evaporator types, ensuring longer run times.
- Superior Crystal Quality: The controlled supersaturation in the forced circulation crystallizer yields uniform, easily separable crystals.
- Environmental Compliance: Enables effective volume reduction of wastewater, facilitating ZLD strategies and resource recovery.
- Reduced Maintenance: The design minimizes scaling, leading to less frequent cleaning and lower long-term upkeep costs.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a forced circulation design over a natural circulation one?
A: Forced circulation uses a pump to maintain high fluid velocity through the heater tubes. This is critical for processing feeds with high viscosity, suspended solids, or a tendency to scale, as it prevents settling and fouling, ensuring stable heat transfer and continuous operation.
Q2: Can this 10 T/D system handle feed streams with high salt content or organics?
A: Absolutely. The forced circulation evaporator is specifically suited for such challenging feeds. The material of construction (e.g., 316L SS or higher alloys) can be selected based on a detailed analysis of your feed composition to ensure corrosion resistance.
Q3: What is the typical steam consumption for this four-effect unit?
A: While it depends on the specific feed and operating conditions, a well-designed four-effect forced circulation evaporator typically consumes approximately 0.3 to 0.35 kg of steam per kg of water evaporated, offering excellent energy economy.
Q4: Is the system delivered as a skid-mounted package?
A> Yes, we typically design and fabricate major components as pre-assembled skids. This minimizes on-site installation time and cost, ensuring faster commissioning. The level of skidding (full plant or modular) can be discussed during the engineering phase.
Q5: Do you provide automation and control systems?
A: We offer various levels of control, from basic semi-automatic panels to fully integrated PLC-based systems with SCADA interface for remote monitoring. The choice depends on your operational needs and budget.
Q6: What after-sales support do you offer?
A: Our support includes detailed installation guidance, comprehensive operational training for your personnel, a warranty period, and the availability of spare parts. Remote technical support is also available.
Q7: Can the equipment be customized for a different capacity or a specific product output (e.g., specific crystal size)?
A: Certainly. As a manufacturer, we specialize in custom engineering. We can scale the design up or down from the 10 T/D base model and tailor the crystallizer parameters to influence the final crystal size distribution as required.
Q8: What are the common applications for this type of equipment?
A: Common applications include: concentration of industrial wastewater for ZLD, recovery of salts (e.g., sodium sulfate, ammonium chloride) from process streams, concentration of caustic solutions, and production of high-purity chemicals via crystallization.
