Product introduction
The double effect evaporator system is an energy-saving evaporation device that improves thermal energy utilization by connecting two or more evaporators in series. Double-effect evaporator system is an efficient, energy-saving evaporation equipment, suitable for a variety of industrial fields, especially in the need for a large number of evaporation and crystallization operations show its advantages.
Double effect evaporator system composition
The composition of double-effect evaporator system mainly includes: two-effect heater, two-effect separator, condenser, hot pressure pump (optional), vacuum and drainage system, circulation or conveying pump, operating platform, electric control cabinet, valve pipeline and other systems.
Double effect evaporator system features
1. Energy saving and consumption reduction: By utilizing the heat of the secondary steam, the double-effect evaporator system significantly reduces energy consumption. In the double-effect evaporation process, the second effect heater uses the secondary steam generated by the first effect to heat, which not only saves energy, but also reduces the need for cooling water.
2. High degree of automation: double-effect evaporator system can be equipped with CIP cleaning system to achieve on-site cleaning and easy operation. At the same time, the equipment can be continuously in and out of the material, and can be configured with an automated system to achieve automatic control of the feed amount, heating temperature, discharge concentration and cleaning.
3. Complete equipment protection measures: The double-effect evaporator system can also be equipped with automatic operation and control such as sudden power failure, protection measures for materials in case of failure and alarm to ensure the low-consumption operation of the whole evaporator system.
4. Strong adaptability: the double-effect evaporator system is suitable for the solution evaporation and concentration needs of different industries, and can handle various types of materials, such as industrial production in chemical, food, pharmaceutical and other industries, and is also commonly used in industrial wastewater treatment.
5. Pollution-free emission: In the double-effect evaporator system, the secondary steam has been fully utilized, avoiding the environmental pollution caused by direct emission in the traditional single-effect evaporator.
6. Space saving: Compared with multiple single-effect evaporators in series, the double-effect evaporator system is highly integrated, occupies a small area, and saves installation space.
7. Low operating costs: Due to the remarkable energy-saving effect, the operating costs of the double-effect evaporator system are reduced, which saves a lot of energy costs for enterprises.
8. Crystallization function: For materials that need crystallization, the double-effect evaporator system can achieve efficient crystallization and improve product quality.
Double effect evaporator system application field
Chemical industry: In the chemical industry, double-effect evaporators are used in the production and preparation process of ammonium nitrate, caustic soda, antibiotics and other chemicals, as well as the treatment of industrial wastewater.
Light industry: In light industry, double-effect evaporators can be used for evaporation and concentration in the sugar making process to improve production efficiency.
Food industry: In the food industry, double-effect evaporators are used for the concentration of food liquids, such as the processing of juice, milk, etc.
Environmental protection industry: Double-effect evaporator is also widely used in the field of environmental protection, especially in industrial wastewater treatment, such as chemical, pharmaceutical, metallurgy, mining, petrochemical, rare earth, lithium, hazardous waste and other industries in the wastewater treatment process, double-effect evaporator can effectively reduce energy consumption, to achieve economic water treatment solutions.
Technical principle of
Double-effect evaporator technology principle:
First effect evaporation: the raw material liquid first enters the first effect heater, where it is heated to a boiling state by an external heat source (such as raw steam), causing some of the water to vaporize. This process is called primary evaporation.
The use of secondary steam: the secondary steam generated in the first effect heater is not directly discharged, but is used as the heat source of the second effect heater. In this way, the raw material liquid in the secondary heater can be vaporized again using the latent heat of these secondary vapors, thus saving the need for external heat sources.
Second effect evaporation: the raw material liquid after the first effect preheating enters the second effect heater, where it is heated by the secondary steam generated by the first effect for secondary evaporation. This process further increases the concentration of the solution.
Energy saving: Since the secondary evaporation uses the secondary steam that would otherwise be expelled, the energy efficiency of the entire system is significantly improved. Compared to single-effect evaporation, dual-effect evaporation can save about 50% of energy consumption.

Frequently Asked Questions
Q: Why does the vacuum degree decrease during the operation of the double-effect evaporator?
A: The decrease in vacuum degree may be caused by system leakage, reduced vacuum pump performance or severe solution boiling. Check the tightness of the equipment, repair or replace the vacuum pump, and optimize the operating parameters to stabilize the vacuum.
Q: Why does the temperature rise during the operation of the double-effect evaporator?
A: The temperature increase may be caused by too high heating steam pressure, insufficient cooling effect of the condenser, or too high solution concentration. The heating steam pressure should be adjusted to enhance the cooling effect of the condenser, and the solution concentration should be controlled to avoid temperature increase.
Q: How to improve the efficiency of double-effect evaporator?
A: Improving operating efficiency can be achieved by optimizing operating parameters, cleaning and maintaining equipment regularly, improving equipment design, and using energy-saving technologies. Ensuring that equipment is operating in optimal conditions is the key to improving efficiency.
Q: Why does the double-effect evaporator crystallize during operation?
A: Crystallization may be due to supersaturation of the solution or improper temperature control. The concentration and temperature of the solution should be controlled to avoid exceeding the saturation of the solute, and the equipment should be cleaned regularly to prevent scaling.
Q: How to extend the service life of double-effect evaporator?
A: Extending service life requires regular maintenance and maintenance, including cleaning equipment, checking and replacing worn parts, optimizing operating parameters, etc. Following the correct operating procedures and using high-quality raw materials also help extend the life of the equipment.
