Technological Advantage
Main Production Equipment

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.


Spray Basket
The Spray Basket is a specialized device designed to atomize liquid sodium hydroxide solution into fine droplets, widely used in spray drying processes. Its precise internal structure ensures that the liquid is uniformly sprayed at high pressure, improving drying efficiency and particle quality.
Operating Principle: The sodium hydroxide solution is delivered to the Spray Basket’s interior through a high-pressure pump. The Spray Basket converts the high-pressure liquid into uniform atomized droplets, which rapidly evaporate moisture under the influence of hot air, ultimately forming dried granular solids. The design can be adjusted to modify droplet size, optimizing drying and shaping effects.
Main Features:
Efficient Spraying: The precise design of the Spray Basket ensures uniform spraying, enhancing drying rates and particle quality.
Effective Separation Design: Ensures that most particles do not escape into the exhaust, improving resource utilization.
High Adaptability: Capable of handling liquids of varying viscosities and properties, meeting diverse production needs.
Easy Maintenance: The simplified structure design facilitates routine maintenance and cleaning, reducing operational costs.
