Two stage membrane separation experimental machine

Product introduction：

The two-stage membrane separation experimental machine (DMJ60-2) can be equipped with microfiltration, ultrafiltration, nanofiltration and reverse osmosis membrane elements. It can realize single-stage filtration or two-stage continuous filtration at the same time. It can start ultrafiltration and nanofiltration membrane at the same time to complete the clarification and filtration of product solution. It can also realize graded ultrafiltration, nanofiltration concentration, desalination, dealcoholization and reverse osmosis concentration. In the same time period, the product solution was collected according to the size of molecular star, and the whole process was continuously controllable.

Description of equipment structure：

1. The secondary membrane separation and filtration system can be replaced with microfiltration, ultrafiltration, nanofiltration and reverse osmosis membrane elements. It can realize single-stage filtering or two-stage continuous filtering at the same time;

2. At the same time, ultrafiltration and nanofiltration membrane can be started simultaneously to complete the clarification and filtration of product solution, as well as step ultrafiltration, nanofiltration concentration, desalination, dealcoholization and reverse osmosis concentration. At the same time, the product solution was collected in stages according to the molecular weight, and the whole process was continuously controllable;

3. The secondary nanofiltration membrane is equipped with a 0.2 square meter tubular heat exchanger, which fully ensures the temperature control in the nanofiltration concentration process;

4. Membrane element: equipped with a reverse osmosis membrane element. The membrane components meet the FDA. USDA, 3-A health standards;

5. The meteor range of the pump is completely configured according to the membrane surface velocity of the sanitary grade membrane element, which can ensure that the experimental parameters selected by the experimental equipment can be directly enlarged to the industrial production;

6. According to the fluid dynamics design, the membrane shell can fully ensure the membrane surface velocity and the stability and reliability of the test data;

7. With automatic overpressure protection function, overpressure automatic shutdown, ensure the safety of the use process;

8. With temperature control module, over temperature automatic shutdown, to ensure the stability of materials in the experimental process; Can set high and low temperature alarm, automatic start and stop; Timing start stop function can be set;

9. Other types of organic microfiltration, ultrafiltration, nanofiltration and reverse osmosis membrane elements can be replaced;

10. All stainless steel welding adopts automatic argon filling protection, single-sided welding and double-sided forming. The internal and external surface quality of the pipeline is excellent, and there is no welding point in the pipeline in contact with the material, so as to ensure the pressure resistance and corrosion resistance of the equipment and the operation of the equipment。
