As a leading manufacturer specializing in advanced environmental solutions since 2015, Qingdao Conqinphi Environmental Technology Group is proud to introduce our All-in-One Vacuum Evaporator. Engineered for demanding industrial applications, this integrated system represents a significant leap forward in sustainable wastewater management. It is designed not merely as a treatment unit but as a comprehensive resource recovery platform, transforming waste streams into valuable assets while drastically reducing disposal volumes and costs. Operating from our expansive 10,000-30,000 square meter facility with a dedicated team of over 200 professionals, we have developed this evaporator to meet the complex challenges faced by industries worldwide, offering a reliable, efficient, and economically viable path to environmental compliance and operational excellence.
Our All-in-One Vacuum Evaporator system is meticulously engineered to deliver exceptional performance through a combination of advanced features and robust construction.
- Integrated Modular Design: The system combines pre-filtration, vacuum evaporation, vapor condensation, and automated control into a single, skid-mounted unit. This simplifies installation, reduces footprint, and ensures seamless process integration.
- High-Efficiency Heat Transfer: Utilizing a forced circulation or falling film design under vacuum conditions, the system achieves superior heat transfer coefficients, leading to lower energy consumption per unit of water evaporated.
- Advanced Automation: Controlled by a user-friendly PLC with a touchscreen Human-Machine Interface (HMI), the system allows for precise control over parameters like temperature, pressure, feed rate, and concentration levels. Automated cleaning cycles (CIP) minimize downtime and maintenance.
- Corrosion-Resistant Construction: Critical wetted parts are constructed from high-grade stainless steel (e.g., 316L or duplex) or other specialized alloys to withstand aggressive wastewater chemistries, ensuring long service life and reliability.
- Resource Recovery Focus: The core value proposition. The system concentrates dissolved solids, heavy metals, or other contaminants into a small volume of slurry, while producing high-purity distillate suitable for reuse (e.g., cooling tower makeup, rinse water) or safe discharge. Valuable components can often be recovered from the concentrate.
- Energy Optimization Features: Designs often incorporate heat recovery systems, such as vapor recompression (MVR or TVR), to recycle the latent heat of evaporation, dramatically improving thermal efficiency and reducing operating costs.
The technical specifications of the All-in-One Vacuum Evaporator are tailored to specific application requirements. Below is a representative overview of key parameters:
| Parameter | Typical Range / Specification |
| Evaporation Capacity | From 1 to 50 tons per day (customizable) |
| Final Concentration Rate | Up to 95%+ Total Solids (TS) |
| Distillate Quality | Typically < 50 ppm TDS (depending on feed) |
| Operating Pressure | High vacuum range (e.g., 50-150 mbar abs) |
| Heating Medium | Electric, Steam, or Hot Thermal Oil |
| Control System | PLC with Touchscreen HMI, data logging optional |
| Main Construction Material | SS304, SS316L, Titanium, or Duplex Stainless Steel |
The benefits for our clients are substantial and multi-faceted. Operational Cost Savings are realized through reduced wastewater hauling and disposal fees, lower chemical usage, and energy-efficient operation. Regulatory Compliance is achieved by meeting stringent effluent standards and enabling Zero Liquid Discharge (ZLD) strategies. Sustainability Goals are supported through water recycling and resource recovery, enhancing corporate social responsibility profiles. Finally, the all-in-one, automated design minimizes labor requirements, reduces operational complexity, and provides a reliable, low-maintenance solution for continuous industrial processes.
Backed by nearly a decade of manufacturing expertise and a robust portfolio of quality management certifications including ISO 9001 and ISO 14000, Qingdao Conqinphi stands as a trusted partner for industries across the globe. Our products, exported to markets in North America, Europe, Asia, and beyond, with an annual export value in the range of US$10-50 million, are a testament to our commitment to international standards and customer satisfaction. This All-in-One Vacuum Evaporator embodies our mission: delivering technologically advanced, reliable, and cost-effective environmental solutions. We invite you to contact us to discuss how this system can be customized to address your specific wastewater challenges and turn your treatment liability into a recovery opportunity.
Frequently Asked Questions (FAQ)
Q1: What types of industrial wastewater are suitable for this vacuum evaporator?
A: It is highly effective for a wide range of streams, including but not limited to: metal finishing rinse waters, plating baths, landfill leachate, chemical process water, pharmaceutical effluents, and textile dyeing wastewater. A feed analysis is recommended for precise suitability assessment.
Q2: How does the vacuum evaporation process save energy compared to traditional methods?
A: Operating under vacuum lowers the boiling point of water, requiring less thermal energy. Furthermore, optional Mechanical Vapor Recompression (MVR) technology recycles the heat from the evaporated vapor, achieving high thermal efficiency and significantly reducing steam or electrical energy consumption.
Q3: What is the typical maintenance requirement for this all-in-one system?
A: Maintenance is minimal due to automated operation and clean-in-place (CIP) functions. Routine checks involve pumps, instrumentation, and the control system. The corrosion-resistant materials reduce wear from aggressive chemicals. A recommended preventive maintenance schedule is provided.
Q4: Can the distillate water produced be reused within our plant?
A: Yes, in most cases. The distillate is typically high-purity water with very low conductivity. It is often suitable for reuse as boiler feed water, cooling tower makeup, or in various rinsing processes, supporting water conservation goals.
Q5: How is the concentrated waste (brine/slurry) handled after evaporation?
A: The volume reduction is drastic (often 90-95%). This small volume of concentrate can be sent for specialized disposal, further processed for crystal recovery, or in some cases, used as a feedstock. We can advise on final disposal or valorization options based on its composition.
Q6: Is the system scalable for different wastewater flow rates?
A: Absolutely. We design and manufacture systems with modular scalability. Capacities can be tailored from pilot-scale units (a few hundred liters per day) to large industrial systems handling tens of cubic meters daily. The all-in-one design philosophy scales accordingly.
Q7: What level of automation and monitoring does the control system offer?
A: The PLC-based system offers full automation of start-up, operation, shutdown, and cleaning cycles. The HMI provides real-time monitoring of all critical parameters (flow, pressure, temperature, conductivity), alarm management, and data logging for process optimization and reporting.
Q8: What support do you provide after installation?
A: Our support includes comprehensive commissioning supervision, operator training, detailed operation & maintenance manuals, and readily available spare parts. Remote diagnostics support is also available. We are committed to ensuring the long-term performance of your investment.
