Introduction: The double-film tank flat diaphragm test equipment is a multi-functional diaphragm test and material separation equipment, which is suitable for the performance test of microfiltration membrane, ultrafiltration membrane, nanofiltration membrane, reverse osmosis membrane, seawater/brackish water desalination membrane and the like. , including water flux, retention rate and other performance parameters. It is also suitable for a small amount of liquid filtration and teaching demonstrations. Features: 1. Flat membrane test The small test equipment belongs to the membrane test and filtration equipment, and is suitable for filtration test and test of microfiltration membrane, ultrafiltration membrane, nanofiltration membrane and reverse osmosis membrane.
2. The whole equipment is equipped with a heat exchange cooling unit. The cooling adopts jacket heat exchange, and the external cold source (chiller or tap water) controls the temperature rise. 3. The membrane pool adopts parallel design, but the corresponding valve is replaced. One membrane pool can be used alone or two membrane tanks can be used at the same time. Flow sensing and pressure sensing are installed on each membrane pool. Monitor flow and system pressure, and the dialysate outlet is attached to a precision balance for data collection, which can feedback system parameters in real time; 4. The pressurized power component needs to adopt imported plunger diaphragm pump, which has high pressure, high efficiency, corrosion resistance and strong self-suction capability; the return line and dialysis pipeline can adopt hose design; the main machine requires stainless steel pipeline and fittings. It can withstand high pressure, corrosion resistance and good sealing. 5. The overall structure is compact and easy to operate; the system needs to be equipped with multiple safety protections, including safety relief valve and energy storage shock absorber, which can automatically relieve pressure when the pressure is too high, and can avoid pressure fluctuations and make the fluid run smoothly. Reduce the pulse; the equipment is equipped with variable frequency speed control, the flow and pressure can be adjusted freely, and the impact of the water hammer on the diaphragm is avoided. 6. The system is equipped with on-line temperature, flow, pressure, conductivity meter and other corresponding sensors. The equipment adopts PLC+ industrial tablet computer to control the operation and display. It has the function of data recording to reduce the labor intensity and record the test process data in real time. Technical Parameters: 1. Design pressure: 4.0MPa (system withstand voltage) 2. Operating pressure: ≤3.0MPa 3. Membrane shape: rectangular, 5*8cm 4. Number of membrane pools: 2 5. Applicable diaphragm: microfiltration, ultrafiltration, nanofiltration, reverse osmosis 6. System filtration capacity ≥20ml/h-1L/h (depending on diaphragm filtration accuracy and material characteristics) 7. Material circulation volume: ≥1L 8. Equipment power: 1.5 kW 9. System temperature resistance: 5-65 oC
