As a leading manufacturer in environmental technology, Qingdao Conqinphi Environmental Technology Group is proud to present our advanced Temperature Resistant Multi-Effect Plant for Wastewater Treatment, featuring a high-efficiency Forced Circulation Evaporator core. With our foundation established in 2015 and operations spanning a 10,000-30,000 square meter facility, we specialize in engineering robust solutions for complex industrial effluent challenges. This system is engineered to tackle high-salinity, high-COD, and difficult-to-treat wastewater streams, transforming them into manageable concentrates and high-purity distillate, thereby helping clients achieve zero liquid discharge (ZLD) goals, recover valuable resources, and ensure stringent environmental compliance.
The core of this plant is the forced circulation evaporation technology, which is distinctly different from natural circulation or falling film evaporators. It is specifically designed for wastewater with a high fouling tendency, high viscosity, or containing crystallizing salts. The system's design prevents scaling and plugging, ensuring stable, long-term operation with minimal maintenance downtime—a critical advantage for continuous industrial processes.
Core Technology & Operational Advantages:
- Multi-Effect Design for Superior Energy Efficiency: The plant utilizes multiple effects (commonly 2 to 5 effects) in series. The vapor generated in the first effect becomes the heating source for the second, and so on. This cascading reuse of latent heat dramatically reduces steam consumption, often by 50-70% compared to single-effect evaporators, leading to significant operational cost savings.
- Robust Forced Circulation Mechanism: A high-flow recirculation pump maintains a high velocity of the wastewater inside the heating tubes. This forceful flow creates strong turbulence, which enhances heat transfer coefficients and, more importantly, prevents solids from settling and scaling on the tube walls. This is essential for handling wastewater with suspended solids or salts near their crystallization point.
- High-Temperature Resistance & Material Integrity: Constructed from premium corrosion-resistant materials like SS316L or duplex stainless steels for critical components, the system is built to withstand aggressive chemical environments and elevated operating temperatures, ensuring longevity and reliability.
- Adaptable to Various Heat Sources: The system can be configured to use low-pressure steam, thermal oil, or even electric heaters as the primary heat source, offering flexibility based on the client's available utilities and energy cost structure.
- Comprehensive Automation & Control: Integration with a PLC-based control system allows for precise monitoring and regulation of key parameters such as temperature, pressure, level, and density. This enables fully automatic operation, optimizes performance, ensures safety, and reduces labor requirements.
Technical Specifications & Configuration Options:
The system is highly customizable. Below is a reference table for common configuration parameters:
| Parameter | Typical Range / Options | Description |
| Evaporation Capacity | 1 - 100 tons of water/hour | Custom-designed based on influent flow and concentration ratio. |
| Number of Effects | 2, 3, 4, 5, or MVR (Mechanical Vapor Recompression) | More effects increase energy efficiency but also capital cost. |
| Heat Exchanger Tube Material | SS304, SS316L, Titanium, Duplex Steel | Selected based on wastewater chemistry (pH, chlorides, etc.). |
| Final Concentrate Solid Content | Up to 40-60% (or until slurry) | Maximizes volume reduction, minimizing disposal costs. |
| Distillate Quality | Typically | High-purity water recovered, adding value to the process. |
Client Benefits & Application Scenarios:
- Significant Cost Reduction: Drastic lowering of wastewater hauling and disposal fees through volume reduction. Energy-efficient design minimizes utility costs.
- Resource Recovery & Revenue Potential: Allows for the recovery of clean water for internal reuse. In some cases, concentrated by-products may have value or be easier to process further.
- Regulatory Compliance & Sustainability: Enables companies to meet increasingly strict environmental regulations regarding discharge or to work towards Zero Liquid Discharge (ZLD), enhancing corporate sustainability credentials.
- Process Reliability: The forced circulation design ensures stable operation even with challenging feedstocks, reducing unplanned shutdowns and associated production losses.
- Wide Industry Application: Ideal for wastewater from chemical/pharmaceutical production, power plant FGD, mining, textile dyeing, landfill leachate, food processing, and metal finishing.
FAQ (Frequently Asked Questions)
-
Q: What is the main difference between a forced circulation evaporator and a falling film evaporator for wastewater?
A: Forced circulation uses a pump to create high fluid velocity, making it ideal for viscous, scaling, or crystallizing fluids. Falling film relies on gravity and is better for heat-sensitive, non-scaling liquids. For tough industrial wastewater, forced circulation offers superior fouling resistance. -
Q: How do you determine the optimal number of "effects" for our project?
A: The choice involves a trade-off between energy savings (more effects save more steam) and higher initial investment. We perform a detailed technical-economic analysis based on your specific wastewater flow, concentration target, and local energy costs to recommend the most cost-effective configuration. -
Q: Can this system handle wastewater with fluctuating quality or flow rate?
A: Yes. The PLC control system is designed to adjust pump speeds, heating rates, and valve positions to accommodate reasonable variations in feed conditions, maintaining stable product quality. -
Q: What kind of pre-treatment is required for the wastewater before entering the evaporator?
A: Typically, suspended solids should be removed (e.g., via filtration) to protect pumps and avoid excessive fouling. Hardness may need softening if scaling is a concern. We provide complete process design, including necessary pre-treatment recommendations. -
Q: What is the expected lifespan of the key components, like the heat exchanger?
A: With proper material selection (e.g., SS316L for chlorides) and routine maintenance, the main evaporator vessel and heat exchanger can have a service life exceeding 15 years. The recirculation pump, as a wearing part, may require more frequent attention. -
Q: Do you offer a pilot test or treatability study before designing a full-scale system?
A> Yes, we strongly recommend and can arrange for pilot testing using a small-scale unit on a sample of your actual wastewater. This provides critical data on fouling rates, achievable concentration, and distillate quality, de-risking the full-scale project. -
Q: Is the recovered distillate water pure enough to be reused as boiler feed water or cooling tower makeup?
A> In most cases, yes. The distillate from a multi-effect evaporator is typically very high purity, with low conductivity and organics. It may require minor polishing (e.g., ion exchange) for specific high-purity applications like boiler feed, but is often directly suitable for cooling towers or rinsing processes.
