The technical advantage of the triple-effect evaporator is that it can effectively save energy and improve thermal efficiency. Through the three-stage evaporation process, one portion of steam can be put in, and many times of water can be evaporated, and the solid-liquid separation of salt and wastewater can be realized at the same time.

Three effect evaporator composition

A triple-effect evaporator consists of several key components that work together to achieve an efficient evaporation process. Here are its main components:
Feed pump: responsible for the material to be treated into the first effect heater.
Single-effect heater: The use of external heat sources (such as raw steam) to initially heat the material so that it reaches boiling state.
Two-effect and three-effect evaporator: the secondary steam generated by the first effect will enter the second-effect evaporator as a heat source, and the secondary steam generated by the second effect will be sent into the third-effect evaporator, so as to form a series process of three-effect evaporation.
Evaporation chamber and separator: Here, the heated material is evaporated, and the vapor is separated from the unevaporated liquid through the gas-liquid separator.
Circulating pump: the separated liquid is transported back to the heater to form a circulating flow process.
Condenser: used to condense the evaporating steam for collection or further processing.
Salt separator: In the evaporation process, if there are solid substances, such as salt, they will be separated here.

Three effect evaporator features

1. High energy saving efficiency: the three-effect evaporator greatly improves the utilization efficiency of heat energy through the three evaporation process. It can achieve efficient evaporation with lower energy consumption, saving about 70% of evaporation compared to single-effect evaporators.
2. Easy to operate: the system is usually equipped with an intelligent control system, which can achieve accurate control and calculation of heat in the evaporation process, thereby improving the efficiency of energy utilization.
3. Clean and hygienic: the material is evaporated and concentrated in the closed system, and the environment is clean and comfortable. The unique foam removal device of the equipment prevents the phenomenon of running material, and the part in contact with the material is usually made of imported stainless steel, and is polished, making the equipment has good corrosion resistance, convenient cleaning, and meets the health requirements of the food and pharmaceutical industry.

Triple effect evaporator application field

Chemical production: In the chemical industry, triple-effect evaporators are used to treat saline wastewater, especially those with a salt content of 3.5% to 25% (mass percentage), as well as wastewater with COD concentrations of 2000 to 10,000ppm. These wastewater may come from the production process of chemical products, and the three-effect evaporator can effectively remove the inorganic salts through evaporation to achieve the purpose of purification and concentration.
Food processing: In the food industry, the three-effect evaporator is suitable for the concentration process of liquid food, such as the processing of juice, milk, etc., to help improve the concentration of the product, while retaining the original flavor and nutrition of the food.
Oil and gas capture and processing: In these industries, triple-effect evaporators are used to treat the treatment of brine to reduce environmental impact.

The principle of triple-effect evaporator technology is based on multiple stages of evaporation and heat reuse to improve overall energy efficiency and production efficiency.
First, a triple-effect evaporator is a system composed of three evaporators in series. During operation, the pressure and solution boiling point of each subsequent effect are lower than that of the previous effect, so that the secondary steam produced by the previous effect can be used as a heating medium for the next effect. In other words, the heating chamber of the after-effect is actually the condenser of the pre-effect secondary steam. In general, the first effect requires the consumption of raw steam to provide heat, while the subsequent second and third effects rely mainly on the secondary steam generated by the previous effect for heating.

Second, this design has the advantage of significantly reducing energy consumption, since no additional heat source is required for all effects except the first. The condensate of the first effect is returned to the heat source, while the condensate of the other effects is pooled and exported as desalinated water. Through this process, a single raw steam input can evaporate many times the amount of water.

In addition, in practical industrial applications, three-effect evaporators are particularly suitable for the evaporation and crystallization of solutions that have crystal precipitation. They are widely used in chemical industry, metal mining smelting, large steel pickling waste liquid treatment and power plant wet desulfurization waste liquid treatment. Due to the complex and changeable characteristics of the solution in various factories, it is usually necessary to formulate specific technical solutions for users to choose from for the composition and content of the solution with crystal precipitation.
