Reverse osmosis online water quality parameter acquisition system

Abstract

The invention discloses a reverse osmosis online water quality parameter collection system, which comprises a reverse osmosis membrane shell, n (n≥1) reverse osmosis membrane elements connected in sequence and fixed in the reverse osmosis membrane shell, and a reverse osmosis membrane element fixed in the center of the reverse osmosis membrane element. The reverse osmosis membrane probe inside the tube; there are m (1≤m≤n) sampling tubes inside the reverse osmosis membrane probe, and the inlet port of each sampling tube is set at the end of the central tube of the corresponding reverse osmosis membrane element to obtain the corresponding The sample water corresponding to the end of the reverse osmosis membrane element, the outlet end of the sampling tube passes through the end of the reverse osmosis membrane probe and the end of the central tube, and then connects to the conductivity monitor. The present invention can obtain the sample water conductivity at the end of the central tube of each membrane unit in real time, thereby calculating and obtaining other water quality parameters, and realizes the real-time monitoring of the operating state of a single membrane without shutting down the membrane to remove the membrane.

Description

technical field [0001] The invention relates to a data collection system, in particular to an online water quality parameter collection system used in a reverse osmosis system. Background technique [0002] During the operation of the reverse osmosis system, the operating status of the reverse osmosis membrane can be judged through its operating pressure difference and the water quality of the product, which is used to guide the maintenance and replacement of the membrane system. Traditional reverse osmosis units are generally only equipped with monitoring of inlet water pressure, concentrated water pressure, inlet water quality and product water quality, but because most of the reverse osmosis membrane shells are equipped with multiple sets of reverse osmosis membrane units, it is difficult to obtain the data from the above data. Judging the operating status of a single membrane, so it is difficult to judge the operating status of a single membrane from the above data. If y...

Traditional reverse osmosis units are generally only equipped with monitoring of inlet water pressure, concentrated water pressure, inlet water quality and product water quality, but because most of the reverse osmosis membrane shells are equipped with multiple sets of reverse osmosis membrane units, it is difficult to obtain the data from the above data. Judging the operating status of a single membrane, so it is difficult to judge the operating status of a single membrane from the above data. If you want to know the operating status of a single membrane, you must disassemble the reverse osmosis unit and monitor one by one, and at the same time judge the water quality Manual probes are also required to detect one by one, which brings considerable difficulty to judge the reverse osmosis membrane system
