The online conductivity detector for seawater desalting comprises a conductivity sensor; a water inlet and a water outlet of a seawater-desalting system are respectively connected with a water outlet of a seawater-measuring pond and a water inlet of a freshwater-measuring pond; the two measuring ponds are in closed structure; the conductivity sensor penetrates through the top cover of the measuring ponds and is connected with the input end of a signal acquisition circuit the output end of which is connected with the input end of an embedded controller by signals; the embedded controller is connected with a touch monitor by a serial port; and the output control end of the embedded controller is connected with an ultrasonic controller by signals and the ultrasonic controller is respectively connected with ultrasonic generators. The detector is simple, convenient and visualized to operate, is easy to maintain and can realize the functions, such as the online detection of conductivity parameters during seawater desalting, periodical system correction and automatic sensor electrode cleaning.

Description

technical field [0001] The invention belongs to the technical field of detection, relates to an on-line detection device, in particular to a device for on-line detection of electrical conductivity in a seawater desalination system. Background technique [0002] With the development of society and economy, the crisis of water resources has become an important problem faced by the whole world. Seawater desalination has become an important source of water in some countries and regions. In the process of seawater desalination, the online detection of water quality parameters is an important means to ensure the normal operation of the seawater desalination system and measure whether the quality of desalinated water is qualified. At present, the online detection parameters of the seawater desalination system mainly include pH, conductivity, temperature, flow, pressure, etc. Among them, conductivity is one of the essential water quality detection parameters in seawater desalinati...

AI Technical Summary

Problems solved by technology

The existing conductivity detection device mainly adopts ordinary conductivity detection instrument, which adopts a discrete installation structure. For example, if the American GF signet conductivity measurement instrument is used, each measurement point must correspond to a conductivity meter, and the cost is relatively high; for online Detection, without electrode cleaning measures, poor anti-pollution performance, long-term use will lead to a decrease in system measurement accuracy
