Multiple Effect Evaporator

Multiple Effect Evaporator

The multi-effect evaporator is a highly efficient industrial device specifically designed to concentrate liquid solutions through the evaporation process, particularly sodium hydroxide solutions. Its core function is to utilize multiple evaporation effects to fully recover steam heat, achieving high efficiency and low energy consumption.

Operating Principle: The operating principle of the multi-effect evaporator involves gradually heating the liquid solution in multiple evaporation chambers, allowing moisture to evaporate and increasing the concentration of the solution. In each evaporation chamber, the steam generated from the previous chamber is used to heat the next chamber, maximizing the utilization of thermal energy.

Main Features

  • Energy-Efficient and Environmentally Friendly: By utilizing multi-effect steam recycling, energy consumption is significantly reduced, enhancing production economy.
  • High Concentration Efficiency: Capable of concentrating liquid solutions to high concentrations, making it ideal for subsequent granulation operations.
  • Corrosion-Resistant Materials: Made with nickel-based alloys or special stainless steel, ensuring long-term stable operation in high-concentration sodium hydroxide environments.
  • Automated Control: Equipped with an automation system that continuously monitors temperature, pressure, and concentration, ensuring safe and stable production.

Falling Film Evaporator

The falling film evaporator is an efficient evaporation device specifically designed for the rapid concentration of liquids. Its unique design allows the liquid to form a thin film on the heating surface, enabling quick evaporation of moisture and significantly improving concentration efficiency.

Operating Principle: In the falling film evaporator, the liquid sodium hydroxide solution forms a uniform thin film along the heating surface and rapidly evaporates during the heating process. The characteristics of the liquid film significantly enhance the evaporation rate, ensuring efficient processing of the product. After evaporation, the concentrated liquid flows out, providing ideal conditions for subsequent processing.

Main Features:

  • Efficient Evaporation: Suitable for handling high-viscosity liquids, capable of achieving rapid evaporation and significantly increasing production efficiency.

  • Low Residence Time: The thin film evaporation reduces the time the liquid spends in the equipment, minimizing the risk of thermal degradation and ensuring product quality.

  • Energy-Efficient Design: Optimized heat transfer design maximizes evaporation efficiency, reduces energy consumption, and achieves economical production.

  • Corrosion-Resistant Materials: Constructed from alkali-resistant materials to ensure long-term stable operation in high-concentration environments.

Caustic Soda Flaking Unit

The caustic soda flaking unit is a key device for producing high-quality caustic soda flakes by converting liquid caustic soda into convenient solid flakes.

Operating Principle: High-concentration liquid caustic soda is sprayed onto the rotating flaker drum, where it rapidly cools and solidifies into flakes. After collection, these flakes are dried to ensure product quality and stability. Throughout the production process, strict quality control measures ensure that the caustic soda flakes meet specific purity and quality standards to satisfy various industrial needs.

Main Features:

  • Specification Standards and Strict Control: The system provides caustic soda flakes in various specifications, with complete width options, uniform thickness, and minimal deviation, ensuring compliance with industry standards.

  • Meticulous Craftsmanship and Smooth Finish: The surface of the flakes undergoes fine processing, resulting in a smooth finish without burrs, preventing injuries, facilitating installation, and enhancing user experience.
