Sodium chloride wastewater evaporator

The sodium chloride wastewater evaporator does not require a condenser, and its structure and process are very simple. It is fully automated, can operate continuously, and is safe and reliable. The equipment is equipped with CIP cleaning pipelines, which can achieve on-site cleaning and make the entire equipment easy to operate. The evaporator is used to evaporate materials under the condition of low temperature and no foam. The liquid is even, without material loss and coking.

　　1、 Characteristics of Sodium Chloride Wastewater Evaporator:

1. Wastewater can be evaporated to meet reuse or discharge standards in one step!

2. The two-step aggregation of wastewater concentration and wastewater salt crystallization is completed in different forms of evaporators, and the salt is separated from the crystallizer in the form of crystals, resulting in good desalination effect!

3. Adopting a multi effect evaporation process, for wastewater with low concentration or salt content, a multi effect tubular falling film evaporator can be used, combined with a crystallization evaporator; For high concentrations or high salt content, a multi effect crystallization evaporator can be used, and a tube type falling film evaporator can be appropriately configured.

4. The newly developed flue gas waste heat and wastewater evaporation equipment can utilize flue gas waste heat for evaporation without generating steam, and the operating cost is very low!

5. Various material equipment can be customized according to user needs!

6. The system operates flexibly and is easy to operate!

　　2、 Sodium chloride wastewater evaporator process:

There are various types of wastewater with diverse characteristics and treatment methods. Some wastewater, due to its high concentration of salts (such as sodium chloride, sodium sulfate, ammonium chloride, zinc sulfate, etc.), cannot be treated by biochemical or other methods, and can only be treated by evaporation desalination to meet discharge standards; Some wastewater can be concentrated through evaporation to turn the substances in the wastewater into treasure.

　　3、 Composition of wastewater desalination evaporator:

1. Preheater: In most cases, the solution to be evaporated must be heated before entering the evaporator.

2. Heater: The solution that needs to be evaporated exchanges heat with the heat source steam in the evaporator, resulting in evaporation. Select different types of evaporators based on the properties of different solutions.

3. Separators: Used for separating steam and liquid, different separators can be selected according to the properties of different solutions, generally including centrifugal separators, gravity separators, or separators with special structures.

4. Its empty system: maintains the vacuum degree of the entire system, extracts some air, non condensable gases, and gases brought in by the solution from the device to achieve a stable evaporation state of the system.

5. Pump: Transport the solution to be evaporated and the concentrated solution. According to the different properties of the solution, different types of pumps can be selected, generally including centrifugal pumps, volumetric pumps, and screw pumps.

6. MVR compressor system: By compressing the secondary steam to provide an evaporative heat source, it improves the heat dissipation of the secondary steam. According to the requirements of different flow rates and compression ratios, multiple compressors can be selected. For situations where the pressure rise is increased, multi-stage compressors can be used in series.

7. Control system: The MVR evaporation system control center adjusts the motor speed, valves, flow meters, temperature, and pressure to achieve automatic evaporation, cleaning, shutdown, and other operations. Automatic alarm, automatic protection system from damage, maintaining dynamic balance of the system.

8. Cleaning system: After evaporating different solutions for a period of time, scaling may occur. Generally speaking, more than 99% of scaling can be removed by adding chemical solvents, and CIP in-situ cleaning or dismantling cleaning can be used.
