In terms of operation mode, the evaporator single-effect equipment can be operated in intermittent, semi-intermittent or continuous mode. In the batch operation, the feeding, evaporation and discharge are carried out step by step; In continuous operation, materials and products are continuously in and out.

Compared with the multi-effect evaporator, the difference between the evaporator single-effect equipment is that it has only one effective evaporating body, and its secondary steam is directly condensed, and the secondary steam is not used for the heating of the next effect like the multi-effect evaporator, which is the reason for its relatively high energy consumption.

Evaporator single-effect equipment is mainly composed of three core parts: feeding system, evaporator and separation system.

The details are as follows:

1. Feeding system: responsible for transporting the liquid material to be treated to the evaporator. This system ensures a steady and continuous flow of material into the evaporator in preparation for subsequent heating and evaporation processes.
2. Evaporator: This is the core part of the evaporator single-effect equipment, where the material receives heat energy and evaporates. Evaporators usually contain a heating chamber with a number of heating tubes in which the material is heated to boiling so that the solvent is converted to steam.
3. Separation system: The gas-liquid mixture produced in the evaporation process needs to be effectively separated, and the separation system is the part that performs this task. It is usually located in the upper part of the evaporator and can separate the evaporated gas from the concentrated liquid, ensuring that the steam is not entrained by the liquid, thus improving the evaporation efficiency.

Evaporator single effect equipment features

Simple equipment: The structure of the evaporator single-effect equipment is relatively simple, so the operation is relatively easy, suitable for small-scale production and intermittent production occasions.
Low cost: Due to the simple structure, the equipment cost of evaporator single-effect equipment is less, and it is a more economical choice for enterprises with limited initial funds.
Strong applicability: evaporator single-effect equipment is suitable for evaporation of a small amount of solution, especially when the material is corrosive or the generated steam is contaminated and can not be reused, evaporator single-effect equipment is a more suitable choice.
Production capacity: The production capacity of the evaporator single-effect equipment is relatively small, which means that it is not suitable for the needs of large-scale continuous production.
High energy consumption: Because the secondary steam generated by the evaporator single-effect equipment is directly condensed and removed, the energy carried by it is not fully utilized, so its energy consumption is higher than that of the multi-effect evaporator.

Evaporator single-effect equipment application field

Chemical industry: In the chemical production process, evaporator single-effect equipment can be used for the recovery of organic solvents, waste liquid treatment, etc., especially suitable for the treatment of corrosive or high-value materials that are not suitable for multi-effect evaporation methods.
Food industry: Evaporator single-effect equipment is widely used in the concentration process of liquid food such as juice and milk, as well as the treatment of wastewater generated in the food processing process.
In addition, according to the different process requirements, evaporator single-effect equipment can also be divided into natural circulation type and forced circulation type, respectively, suitable for different concentrations and characteristics of material treatment.
