Description
Technical Field
[0001] The utility model relates to the technical field of water quality monitoring, and particularly relates to a flow-through measuring cell with a viewing window. Background Art
[0002] The water purification process is one of the important working processes in a natural gas purification plant. In the water purification process, there are two dosing points for adding chlorine dioxide to water. One is for positive-pressure dosing of chlorine dioxide in front of the high-efficiency sedimentation tank to remove algae and divalent iron ions, and the other is for dosing chlorine dioxide at the total outlet position of the domestic water pipeline in the water purification plant for disinfection. The concentration of chlorine dioxide in water is crucial for the impact on water quality and the safe use of water. Generally, a chlorine dioxide monitor needs to be set on the pipeline of the production device. The monitor detects the pH value, residual chlorine concentration, etc. of the flowing water through sensors and electrodes extending into the water to achieve real-time water quality monitoring. The existing chlorine dioxide online monitoring for the water purification process in a natural gas purification plant uses a chlorine dioxide monitor based on the electrochemical method. An electrochemical cell is formed by a working electrode and a reference electrode immersed in water, and the concentration is measured by measuring the potential on the working electrode. In order to ensure the accuracy and stability of the monitoring results, the electrodes need to be calibrated and maintained regularly.

The volume of the shielding cover 5 is enlarged to integrally shield the viewing window 4, which is convenient for the installation and fixation of the shielding cover 5 on the flow-through measurement cell and reduces the improvement cost of the flow-through measurement cell.
[0049] Preferably, the hinge part 8 is provided on the outer wall of the cell body 1 or the side wall or the top of the cell cover 2. The shielding cover 5 adjusts its structure according to the shape of the cell body 1, so that after the shielding cover 5 shields the viewing window 4, it can fit the shape of the cell body 1 to achieve an overall covering of the viewing window 4 area, which can expand the shielding range of the shielding cover 5 and improve the shielding effect of the shielding cover 5.
[0050] Embodiment 4
