HK-1305DEdesulphurizationpHThe monitoring device is a newly launched dual channel device by the companypHOnline measuring instruments, based on the characteristics and regulatory requirements of corresponding water quality monitoring conditions, combined with the company's own technological advantages, have fully summarized more than ten years of on-site experience and vigorously launched a new generation of instruments for desulfurization slurrypHReal time and accurate measurement.

Traditional desulfurizationpHThe electrode is generally installed as shown in the figure1Inside the slurry tank shown, the desulfurization slurry enters from the bottom of the tank and overflows from the top of the tank into the trench. The internal pressure of the slurry tank is relatively high, and with the change of load, the pressure will also change, resulting in unstable electrode liquid contact potential and significant drift; The desulfurization slurry has a fast flow rate and contains large particles. Under this installation method, it will cause significant impact and wear on the electrode bubbles, and the bubbles are prone to rupture; Due to the installation of electrodes in the main channel of the liquid circuit, calcium salts are prone to deposit on the surface of electrode bubbles during long-term use, resulting in inaccurate measurement data.

HK-1305DEdesulphurizationpHThe electrode and flow cell of the monitoring instrument are installed at the outlet of the desulfurization slurry, reducing the impact of pressure changes on the liquid connection and greatly eliminating the influence of pressure changes on measurement; The zero pressure sampling method using an impact flow pool basically eliminates the direct impact of desulfurization slurry and particulate matter in the desulfurization slurry on the bubbles during rapid movement, and greatly slows down the deposition of calcium salts on the bubbles; The automatic flushing water system can periodically or remotely control the electrode flushing, cleaning the electrode bubbles while further delaying the rate of calcium salt deposition on the surface of the bubbles.
