Split-type forced circulation evaporator

Split-type forced circulation evaporator

The modular forced circulation evaporator is an important member of industrial evaporation equipment, playing a key role in various industries, especially in addressing specific process requirements and material characteristics, showcasing unique advantages. Henan Province Jiuyie Chemical Equipment Co., Ltd. has rich experience and outstanding achievements in the research and manufacturing of this type of evaporator.

The equipment consists of heating chamber, separation chamber, circulation pump, and circulation pipeline, among other components, with a modular design. The solution to be evaporated is pumped by the forced feed pump to the inlet of the circulation pipeline of the forced circulation pump, and is forcibly sent into the heating chamber at a certain flow rate. Inside the heating chamber, the solution flows through the tube bundle, where the heating medium outside the tube (such as steam) transfers heat to the solution inside the tube, raising its temperature. The heated solution then enters the separation chamber under the impetus of the circulation pump. Inside the separation chamber, due to the drop in pressure, the solution rapidly boils and evaporates, generating secondary steam. The secondary steam is discharged from the top of the separation chamber after gas-liquid separation, serving as a heat source for the six-effect evaporator; while the concentrated solution continues to circulate within the system until the desired concentration is achieved and is then discharged from the bottom, completing the evaporation concentration process.

Good adaptability

The split-type forced circulation evaporator demonstrates exceptional adaptability for materials with high viscosity, prone to crystallization and fouling. The circulation pump facilitates quick flow of the solution, reducing the residence time of materials on the heating pipe wall, effectively preventing crystallization and fouling. Even when processing materials with higher concentrations and poorer fluidity, it ensures stable operation of the evaporator, guaranteeing the evaporation effect. For example, in the chemical industry, when dealing with suspensions containing a large amount of solid particles, this evaporator can operate continuously and stably without equipment failure caused by material blockage or fouling.

Great operational flexibility

By adjusting the flow rate of the circulation pump and the heating medium, the evaporation strength and concentration ratio of the evaporator can be flexibly adjusted to meet different production process requirements. During production, if there is a need to change the concentration or yield of the product, simple adjustments to relevant parameters can quickly achieve a switch in production goals, providing great convenience for the production operations of enterprises.

Application fields

Chemical industry

Widely used in the production processes of chemical raw materials, such as evaporating and concentrating solutions containing large amounts of impurities and high concentrations of salts during the production of caustic soda and soda ash. At the same time, in the organic chemical field, for the separation and purification of certain reaction products, the split-type forced circulation evaporator also plays an important role, achieving solvent recovery and product concentration through efficient evaporation.

Mining and metallurgy industry

In hydrometallurgy processes, it is commonly used for the evaporation and concentration of leachate. For example, in the extraction processes of metals such as nickel and cobalt, the leachate contains a large number of metal ions and impurities, and the use of a split-type forced circulation evaporator can efficiently concentrate the solution, providing high-concentration raw liquid for subsequent metal extraction processes. Additionally, in alumina production, the evaporator supports enterprises in improving production efficiency and reducing energy consumption by evaporating and concentrating the crude liquid obtained after dissolution thanks to its powerful performance.

Food and beverage industry

In the production processes of products such as juice and syrup, there is a need to concentrate the raw liquid. The split-type forced circulation evaporator can operate under lower temperatures for evaporation, avoiding the destruction of nutrients and flavors in food due to high temperatures. Moreover, its good adaptability and operational flexibility can meet the production needs of different batches and raw materials, ensuring stable product quality.

In the field of environmental protection, particularly in wastewater treatment, especially when dealing with high concentrations of organic and saline wastewater, the split-type forced circulation evaporator is capable of evaporating moisture from the wastewater, achieving the recycling of water resources while concentrating pollutants for subsequent treatment and disposal. In some industrial flue gas treatment processes, it is utilized for the evaporation and concentration of absorbent liquids, allowing for the recycling of absorbents and reducing operational costs.

Pharmaceutical Industry

It is applicable in the concentration and crystallization of drug intermediates, as well as in solvent recovery during the pharmaceutical process. Its precise temperature control and efficient evaporation performance contribute to ensuring the stability and consistency of drug quality, meeting the stringent production standards of the pharmaceutical industry.
