Quadruple-effect forced circulation evaporator

1. Technical Parameters of a Quadruple-Effect Forced Circulation Evaporator

• Evaporation Capacity: 8000-50000 kg/h

• Steam Pressure: 0.5-0.8 MPa

• Steam Consumption/Evaporation Capacity (with heat pump): 0.23

• Evaporation Temperature: 45-90℃

2. Evaporation Efficiency and Energy Consumption

Evaporation Efficiency: The quadruple-effect forced circulation evaporator significantly improves thermal energy utilization efficiency by utilizing secondary steam multiple times. Compared with a single-effect evaporator, the steam consumption of the quadruple-effect evaporator is greatly reduced.

Energy Consumption: The steam consumption of the quadruple-effect evaporator is approximately 0.3-0.35 tons per ton of water. Energy consumption is further reduced by optimizing the temperature gradient and process flow.

3. Structural Features

Heater and Evaporator Separator: Each effect includes a heater and an evaporator separator for heating the material and separating the vapor and liquid.

Forced Circulation Pump: A forced circulation pump ensures rapid material flow within the heater, preventing scaling and dry-wall formation, and improving heat transfer efficiency.

Condenser and Vacuum Pump: Equipped with a condenser and vacuum pump for condensing secondary steam and maintaining system negative pressure.

Automated Control System: An automated system can be configured to automatically control feed, temperature, and concentration, improving operational convenience and stability.

Advantages

1. Wide Adaptability: Suitable for various difficult-to-process materials, including those prone to scaling, crystallization, heat sensitivity, high concentration, high viscosity, and containing insoluble solids.

2. Rapid Forced Circulation: The forced circulation pump ensures rapid material flow within the tubes, guaranteeing uniform heating, preventing dry-wall formation, and improving heat transfer efficiency.

3. Optimized Separation Design: The liquid enters the evaporator separator tangentially, improving vapor-liquid separation.

4. Low-Temperature Vacuum Evaporation: Suitable for heat-sensitive materials, such as the concentration of food sauces.

5. Compact Structure: The equipment has a compact structure, small footprint, and is easy to operate.
