Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established in 2015, with a factory size of 10,000-30,000 sqm and annual export value exceeding US$10 million) proudly presents the Continuous Feed Plate-Type Three-Effect Evaporator with Forced Circulation Anti-Scaling. This advanced evaporation system is designed to maximize concentration efficiency while minimizing energy consumption and scaling issues. Combining plate-type heat exchange, three-effect design, and forced circulation, it delivers reliable performance for industrial wastewater treatment and chemical processing. Whether you need to concentrate high-salinity wastewater or recover valuable solvents, this evaporator offers a robust solution with low operational costs.
The unit's core advantage lies in its anti-scaling plate-type structure, which significantly reduces fouling deposits and extends cleaning intervals. The forced circulation ensures high heat transfer coefficients and prevents hot spots, making it ideal for viscous or fouling-prone liquids. With a continuous feed design, the system operates seamlessly, reducing downtime and labor requirements.
Key Features & Technical Specifications
- Three-Effect Thermal Integration: Achieves energy savings of up to 30-50% compared to single-effect evaporators. Each effect recovers vapor heat from the previous stage, lowering steam consumption.
- Forced Circulation Design: Equipped with circulation pumps to maintain high flow velocity and turbulence, preventing particle sedimentation and scaling on heat transfer surfaces.
- Plate-Type Heat Exchanger: Compact footprint, high heat transfer area per unit volume, easy maintenance, and modular assembly. Plates are made of stainless steel 304/316L with optional anti-scaling coatings.
- Anti-Scaling Mechanism: Special baffle design and periodic reverse flow (optional) reduce crystal adherence. Smooth plate surfaces and optimized flow patterns minimize fouling.
- Continuous Feed Operation: Automated control system ensures stable feed rate and product concentration, allowing 24/7 operation without frequent shutdowns.
- Wide Applicability: Suitable for solutions with high boiling point elevation, high viscosity, or tendency to scale (e.g., brine, caustic soda, sugar, pharmaceutical intermediates).
- Customizable Materials & Components: Options include titanium, Hastelloy for corrosive streams, and various gasket materials. PLC-based HMI for remote monitoring.

Frequently Asked Questions
Q1: What types of liquids can this evaporator handle?
A1: It is suitable for aqueous solutions with moderate to high fouling tendency, high boiling point elevation, or high viscosity. Common applications include brine concentration, caustic soda, sugar syrups, pharmaceutical intermediates, and industrial wastewater.
Q2: How does the anti-scaling design work?
A2: The plate-type heat exchanger features optimized flow channels and periodic reversal of flow direction (optional). The forced circulation maintains a high velocity (2-4 m/s) to keep particles suspended and reduce crystal deposition. Additionally, smooth plate surfaces and optional anti-scaling coatings minimize fouling.
Q3: What is the typical cleaning interval?
A3: Depending on the feed composition, cleaning intervals can range from 15 to 30 days. For heavily scaling streams, an integrated CIP (clean-in-place) system can be added to automate cleaning.
Q4: Can the evaporator be customized for specific capacity and materials?
A4: Absolutely. We offer a wide range of options for evaporation capacity (1-50 t/h), materials of construction (SS304, SS316L, Duplex, Titanium, Hastelloy), and gasket materials. PLC and control system can be tailored to your requirements.
Q5: What is the energy consumption compared to a single-effect evaporator?
A5: A three-effect evaporator typically consumes 30-50% less steam than a single-effect unit. For example, to evaporate 1 ton of water, a single-effect requires about 1.1-1.3 tons of steam, while this three-effect system uses only 0.3-0.4 tons.
Q6: What certifications does Qingdao Conqinphi hold?
A6: Our company holds ISO9001, ISO14000, OHSAS18001, HACCP, SA8000, and other certifications. We also comply with international standards such as ASME (upon request).
Q7: How long is the delivery lead time?
A7: Lead time varies based on capacity and customization level. For standard models, it is typically 30-60 days after deposit. Larger or highly custom units may require 60-90 days.
Q8: What after-sales support do you provide?
A8: We offer online technical support, on-site commissioning assistance (if needed), spare parts supply, and a 12-month warranty. Our service team is reachable via email, phone, or video conference.
