Welcome: Yiwu Weihao Machinery Equipment Company
Yiwu Weihao Machinery Equipment Company designs and produces high performance forced circulation evaporators dedicated to chemical slurry concentration and treatment. This equipment is engineered to solve the pain points of chemical slurry processing such as high viscosity, easy scaling, solid particle deposition, and corrosion, providing a stable, efficient, and reliable solution for chemical industry concentration, crystallization, and resource recovery projects.
Our forced circulation evaporator for chemical slurry is a specialized equipment tailored for high-viscosity, high-solids chemical slurry processing, widely used in chemical, petrochemical, pharmaceutical, and fine chemical industries. Unlike conventional evaporators, it adopts a high-power forced circulation design, combined with anti-clogging and corrosion-resistant structural optimization, to effectively handle chemical slurries containing solid particles (up to 30%) and high viscosity (up to 10,000 cP). The equipment ensures uniform heating, prevents slurry deposition and scaling, realizes efficient concentration and crystallization, and helps enterprises improve production efficiency, reduce material waste, and meet industrial processing standards.
Feed Preparation: Chemical slurry is pre-filtered to remove large solid impurities (above 5mm), adjusted to appropriate viscosity, avoiding blockage of circulation pumps and heating tubes.
Forced Circulation: The pre-treated chemical slurry is pumped into the heating chamber by a high-pressure, anti-clogging circulation pump, forming a high-speed turbulent flow in the heating tubes—this prevents slurry deposition, solid particle adhesion, and scaling on the tube walls.
Heating & Evaporation: The slurry is heated by steam (or hot oil) in the heating tubes, and under vacuum conditions (-0.06 to -0.095 MPa), the solvent in the slurry boils and evaporates at a low temperature (60–90°C), avoiding chemical component degradation.
Vapor Condensation: The generated solvent vapor is condensed into liquid by a condenser, which can be recycled for production or treated up to standard before discharge.
Slurry Concentration & Crystallization: The unevaporated chemical slurry is continuously circulated and concentrated until it reaches the required concentration or saturation state, then enters the crystallization unit for solid-liquid separation—achieving product purification and resource recovery.
Anti-Clogging & Anti-Scaling: High-speed forced circulation creates strong turbulent flow, preventing slurry deposition, solid particle adhesion, and scaling on heating tube walls; optimized tube design and anti-clogging pumps reduce maintenance frequency and avoid equipment downtime.
High Slurry Adaptability: Capable of handling chemical slurries with viscosity up to 10,000 cP and solid content up to 30%, suitable for various chemical slurries (such as pesticide slurry, dye slurry, catalyst slurry, and chemical intermediate slurry).
Corrosion & High-Temperature Resistance: Contact parts are made of high-grade corrosion-resistant materials (316L stainless steel, Hastelloy, titanium alloy optional), resisting corrosion from acidic, alkaline, and organic chemical slurries; high-temperature resistant design adapts to harsh chemical processing conditions.
Efficient & Stable: Forced circulation design ensures uniform heating, high heat transfer efficiency, and stable continuous operation; adjustable concentration ratio and evaporation rate to meet different chemical processing requirements.
Energy-Saving & Cost-Effective: Optional multi-effect or TVR energy-saving configuration, reducing steam consumption by 30–70%; realizing solvent recovery and slurry concentration integration, reducing production costs and environmental pollution.
Easy Operation & Maintenance: PLC + HMI automatic control system, real-time monitoring of temperature, pressure, slurry viscosity, and circulation speed; detachable structure, easy to clean, disassemble, and maintain.
