Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established in 2015) is a leading manufacturer of industrial evaporation systems, with a factory spanning 10,000–30,000 square meters and over 200 skilled employees. Our Forced Circulation Evaporator for Chemical Recovery is engineered to deliver high-efficiency solvent concentration and wastewater treatment, leveraging forced circulation to minimize fouling and scaling. This robust solution is ideal for chemical plants, pharmaceutical industries, and refineries seeking reliable solvent recovery and zero-liquid-discharge (ZLD) compliance.
The forced circulation design ensures a high heat transfer coefficient even when processing viscous or fouling-prone liquids. By circulating the liquid at high velocity across the heat exchanger, it prevents deposits and maintains consistent evaporation rates. Our evaporators are built with premium materials such as SS304, SS316L, or duplex stainless steel, and can be customized to handle corrosive solvents, high-temperature applications, and varying feed compositions.
Key Features & Technical Specifications
- Forced Circulation Mechanism – High-velocity pump ensures turbulent flow, reducing scaling and fouling by up to 80% compared to natural circulation.
- Wide Concentration Range – Capable of concentrating solvents from 5% to 95%+ depending on the chemical properties.
- Vacuum Operation – Optional vacuum system lowers boiling point, suitable for heat-sensitive solvents.
- Energy Efficient – Integrated heat recovery and multi-effect options reduce steam consumption by 30–50%.
- Automated Control – PLC-based system with touchscreen interface, real-time monitoring of temperature, pressure, flow, and concentration.
- Corrosion Resistance – All wetted parts are made of corrosion-resistant alloys or lined with PTFE/PFA as required.
- Compact Footprint – Skid-mounted design for easy installation and integration into existing plants.
- Compliance – Designed to meet ISO9001, ISO14000, and OHSAS18001 standards (certifications held by our factory).

Applications: This forced circulation evaporator is widely used in the following industries:
- Chemical manufacturing – recovery of organic solvents (e.g., methanol, ethanol, acetone, toluene).
- Pharmaceutical production – concentration of active pharmaceutical ingredients (APIs) and solvent recycling.
- Industrial wastewater treatment – reduction of liquid volume, recovery of valuable components, and ZLD systems.
- Food & beverage – concentration of syrups, juices, and extracts (with food-grade options).
- Petrochemical & refining – processing of spent caustic, glycol, and other process streams.
Client Benefits:
- Reduced Operating Costs – Lower energy consumption and minimal maintenance due to anti-fouling design.
- High Recovery Rate – Achieve up to 99% solvent recovery, significantly reducing waste and raw material costs.
- Reliable Performance – Robust construction and quality control ensure long service life with minimal downtime.
- Easy Integration – Skid-mounted, pre-piped, and pre-wired units reduce installation time and cost.
- Compliance Support – Help meet environmental regulations (e.g., discharge limits, solvent emission standards).
