Bielectrode liquid parameter on-line measuring device

Abstract

The invention discloses a bielectrode liquid multi-parameters on-line measuring device which comprises electrodes and a control and parameter detector. The invention is characterized by also comprising a closed cleaning recycling box, two electrode displacement assemblies with the same structure, an electrode cleaning assembly and a cleaning fluid heating constant temperature control device, wherein one side of the closed cleaning recycling box is provided with a liquid detecting tank, and an electrode cleaning fluid and a cleaning pump are arranged in the closed cleaning recycling box; the electrode displacement assemblies are arranged on the cleaning recycling box and provided with one or a plurality of electrode mounting sheathes, and can generate electrode displacement; the electrode cleaning assembly and the cleaning fluid heating constant temperature control device are arranged in the cleaning recycling box; and the electrode cleaning assembly comprises two spaced electrode cleaning positions. Under the control of a controller, the electrodes move into the liquid of the liquid detecting tank, and the generated measurement information is transmitted to a detector through a lead-out wire; and the electrodes move into the cleaning positions of the electrode cleaning assembly so as to be cleaned. The two electrodes can alternately take the measurement and be cleaned, thereby simultaneously measuring one or multiple parameters of the on-line liquid. The invention is applicable to on-line measurement of multiple parameters of various liquids.

Description

technical field [0001] The invention relates to a measuring device, especially an online detection device for liquid parameters. Background technique [0002] In industrial production, the online detection of parameters such as pH value, conductivity, concentration, turbidity, and sulfur dioxide content of liquid is not only the inspection of the results of each process in the liquid production process, but also the main basis for controlling production operations. Liquid parameter online detection has a wide range of applications, such as petroleum, chemical, paper, sugar, pharmaceutical, sewage treatment, food and other processing and production industries. At present, there are many methods and means for online detection of liquid parameters in China, such as conductivity meter, ultrasonic wave, probe (electrode) and nuclear radiation detection device. Among them, the probe (electrode) - hereinafter referred to as the measurement method of the electrode is used more. Th...

Problems solved by technology

The disadvantage of this approach is that it cannot be continuously measured, resulting in the inability to continuously control the chemical reaction and affecting the production of the product.

What they record can only measure a single parameter pH value; and due to the unreasonable design of the direction control rod, the two groups of electrodes cannot be lifted and cleaned together, and the efficiency is low; it is easy to cause failure when the electrodes are lifted and lowered, and the single nozzle is from bottom to top Spray design, poor cleaning effect, acid leakage during acid spray cleaning, and due to structural reasons, electrode replacement is complicated and maintenance is difficult, and a cleaning recovery box needs to be connected to the cleaning liquid outlet, which is inconvenient to install and brings hidden dangers of cleaning liquid leakage
