Product introduction
The technical advantage of the triple-effect concentrator is its excellent energy saving and thermal efficiency. The three-stage concentration process allows a single steam input to produce multiple times the concentration effect, while achieving both purification and enrichment of the solution.
The main components and functions of the three-effect concentrator
Feed pump: responsible for feeding the material to be treated into the first effect heater.
First effect heater: Use an external heat source (such as raw steam) to initially heat the material so that it reaches a boiling state.
Second effect and third effect concentrator: The secondary steam generated by the first effect will enter the second effect concentrator as a heat source, and the secondary steam generated by the second effect will be fed into the third effect concentrator, forming a series process of three-effect concentration.
Concentration chamber and separator: Here, the heated material is concentrated and the vapor is separated from the unconcentrated liquid by a gas-liquid separator.
Circulating pump: The process of re-conveying the separated liquid back to the heater to form a circulating flow.
Condenser: Used to condense the steam produced during the concentration process for collection or further processing.
Solute separator: During the concentration process, if there are solutes precipitated, such as salts, they will be separated here.
Features of the triple concentrator include
High energy saving efficiency: The three-effect concentrator greatly improves the utilization efficiency of heat energy through the three-time enrichment process. It enables efficient enrichment with lower energy consumption, saving about 70% of energy consumption compared to single-effect concentrators.
Easy to operate: the system is usually equipped with an intelligent control system, which can achieve accurate control and calculation of heat during the concentration process, thereby improving the efficiency of energy utilization.
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.
Application areas of the triple-effect concentrator include
Chemical production: The three-effect concentrator can effectively remove the inorganic salt in the solution through the concentration method to achieve the purpose of purification and concentration.
Food processing: The three-effect concentrator 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 harvesting and processing: Three-way concentrators are used to treat the treatment of brine to reduce environmental impact.
Technical principle of
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.

Frequently Asked Questions
Q: What if the heat transfer efficiency of the triple-effect evaporator system decreases?
A: The decrease in heat transfer efficiency may be caused by scale or sediment buildup on the heater surface. The heater needs to be cleaned and maintained regularly, using a CIP (on-site cleaning) system or according to the manufacturer's recommended cleaning procedures to remove dirt. Ensure pre-treatment of incoming materials to reduce components that may form deposits.
Q: How to optimize the energy performance of the triple-effect evaporator?
A: In order to optimize energy consumption, ensure that all operating parameters (such as feed concentration, temperature, pressure, etc.) are precisely controlled. Check and maintain equipment seal performance to avoid steam leakage. At the same time, waste heat can be recovered through energy recovery systems such as heat pumps or thermal recompression, further improving the overall energy efficiency of the system.
Q: What is the cause of excessive noise when the triple-effect evaporator is running?
A: Noise may be caused by the failure or wear of pumps, compressors or other mechanical parts. The equipment should be checked to see if lubrication or parts need to be replaced. In addition, check whether there is air entering the system, because air can cause an air lock phenomenon in the system, producing noise.
Q: How to deal with crystallization blockage in triple-effect evaporator system?
A: Crystallization plugging is usually caused by precipitation of solutes with low solubility at low temperatures. The crystallization process can be controlled by adjusting the operating temperature and pressure, ensuring that the solution evaporates at higher temperatures to avoid crystallization. If a blockage has occurred, the blockage can be dissolved by increasing the temperature or using a chemical solvent.
Q: What if the vacuum degree of the three-effect evaporator can not reach the set value?
A: Insufficient vacuum may be caused by poor vacuum pump performance, system leakage, or inefficient condenser. First, check the performance of the vacuum pump and repair or replace it. Then, the system is fully inspected to determine if there is a leak point and fix it. Finally, clean the condenser to ensure its efficiency.
