Membrane filament flux test stand, membrane filament flux test control system and membrane filament flux test control method

Abstract

The invention relates to a membrane filament flux test stand, a membrane filament flux test control system and a membrane filament flux test control method. The membrane filament flux test stand is characterized by comprising a test water status parameter acquisition device, a parameter adjustment execution device and a controller, wherein the test water status parameter acquisition device is usedfor acquiring test water status parameter signals and sending same to the controller; the parameter adjustment execution device is used for receiving a parameter adjustment control signal and adjusting the test water status according to the parameter adjustment control signal; the controller is used for receiving the test water status parameter signals, comparing the test water status parameter signals with preset test water status parameters, sending parameter adjustment control signals to the parameter adjustment execution device according to the comparison results, and sending the receivedtest water status parameter signals to a display device for displaying. The membrane filament flux test control system can be used for controlling water temperature, water pressure and water storagecapacity of a water tank, thus saving manpower and reducing error; according to the membrane filament flux test stand, the two ends of a membrane filament are clamped by gas claws, so that the experiment precision is improved.

Description

Technical field [0001] The invention relates to the field of water treatment, in particular to a membrane filament flux test bench and its control system and control method. Background technique [0002] Hollow fiber membrane filaments will be affected to varying degrees during production and use, which will change the flux of membrane filaments. Therefore, effective testing and analysis of membrane filament flux can more intuitively show the performance of membrane filaments. [0003] At present, the test method of membrane filament flux is mainly to pass water through one end of the membrane filament, and seal the other end of the membrane filament. The water is discharged through the membrane filament to form a certain stable pressure. The water production of the membrane filament is measured by a graduated cylinder and manually timed. Finally, through the relationship between the water production, the water production time and the effective length of the membrane filament filtr...

Problems solved by technology

[0004] However, the existing test methods measure the flux of the membrane filaments manually, measure the water flow by reading the measuring cup by sight, control the water pressure by manually adjusting the peristaltic pump, and measure the time by manually pinching the stopwatch. Water is passed through one end of the wire, and the other end is closed but there is no locking measure, which makes the whole measurement process cumbersome, with large errors and time-consuming and laborious
