The invention relates to an automatic detection device for a reverse osmosis membrane shell and a detection method thereof. The reverse osmosis membrane casing automatic detection device includes a detection part (1) and a body part (2), and the detection part (1) includes a probe (3) at the top and a moving mechanism connecting the probe (3) and the body part (2) ( 4), the probe (3) movably reaches a predetermined position in the water production central pipe (9) of the reverse osmosis membrane shell (8) via the moving mechanism (4) and detects the conductivity data and flow data at the predetermined position The processing unit (13) is electrically connected to the detection part (1), the drive mechanism (4) and the touch screen (14), and the processing unit (13) generates conductivity trends and flow charts about displacement based on displacement data, conductivity data and flow data trend graph and obtain the location data of the failure point of the water production central pipe (9) of the reverse osmosis membrane shell (8).
Description
technical field [0001] The invention belongs to the field of reverse osmosis, and in particular relates to an automatic detection device and a detection method for a reverse osmosis membrane shell. Background technique [0002] During the operation of the nanofiltration and reverse osmosis membrane system, the desalination rate or water production will attenuate. After finding the faulty membrane shell by locating the leakage point, or when it is necessary to determine whether the desalination rate inside the membrane shell is uniformly or locally decreased, The performance of the membrane element can be detected online by testing the membrane shell by the probe method. [0003] At present, the probe method is used to test the pressure vessel using a plastic tube with a diameter of about 0.6 cm. Insert the plastic hose of the water production center pipe of the entire membrane shell from one end of the membrane shell, and manually test the conductivity of each sampling point...
