Seven-effect Two-stage Evaporator: An Energy-saving Tool for Industrial Production

The seven-effect evaporation of Henan Jiuye Chemical Equipment Co., Ltd. ushers in a new chapter of industrial energy conservation. 

The seven-effect evaporation system is composed of seven evaporators connected in series. Through ingenious design, the secondary steam generated by the previous-effect evaporator serves as the heat source for the next-effect evaporator, achieving the cascaded utilization of thermal energy. This unique operation mode greatly improves the energy utilization rate. Compared with traditional single-effect or multi-effect evaporation, it can significantly reduce energy consumption and operating costs. Taking the production of alumina as an example, the energy consumption for the evaporation and concentration of the mother liquor accounts for more than half of the entire production process. The application of the seven-effect evaporation technology enables enterprises to stably save a large amount of energy expenses in the long run. The steam consumption can be as low as 0.17 tons of steam per ton of water, significantly enhancing the economic benefits of enterprises.

Applications in multiple fields showcase its outstanding performance.

1. Chemical Industry: In chemical production, evaporation and concentration of various solutions are often required. Thanks to its characteristics of high efficiency and energy conservation, the seven-effect evaporation technology is suitable for the treatment of a variety of chemical raw materials. Whether it is a solution with high viscosity, easy crystallization, or heat sensitivity, through reasonable optimization of the process flow, the seven-effect evaporation equipment can achieve stable and efficient evaporation and concentration, providing strong support for the production of chemical products. For example, when producing some fine chemical products, extremely high requirements are imposed on the temperature control during the solution concentration process. The seven-effect evaporation system can operate at a relatively low temperature, meeting the needs of heat-sensitive materials and ensuring the product quality at the same time.

2. Metal Smelting: In the smelting process of the metal mining industry

3. A large amount of solutions containing metal ions will be generated, which need to be evaporated and concentrated to extract metals or recover useful substances. The seven-effect evaporation equipment can adapt to complex solution systems and effectively handle these waste liquids. In the treatment of pickling waste liquids in large steel plants, the seven-effect evaporation can evaporate the water in the waste liquids, reducing the water content of the dry substances to less than 20%, achieving the recycling of resources and reducing environmental pollution simultaneously. 

The seven-effect evaporation technology, with its energy-saving advantages in industrial production and wide range of application fields, has brought tangible benefits to enterprises. With the continuous development and improvement of the technology, it is bound to play an important role in more industrial scenarios, facilitating industrial production to move towards a more efficient and green future.
