[ technical field ] A method for producing a semiconductor device
The utility model relates to a generating set desulfurization technical field especially relates to a PH value measurement system who uses on desulfurization absorption tower.
[ background of the invention ]
The absorption tower in the limestone-gypsum wet flue gas desulfurization process is a core device, and other devices serve the absorption tower. The sulfur dioxide is removed from the flue gas in the absorption tower, and an operator controls the desulfurization efficiency by controlling the slurry parameters of the absorption tower, so that the emission of the sulfur dioxide is reduced. Under the condition of reasonable control of the slurry parameters of the absorption tower, the desulfurization efficiency of the limestone-gypsum wet flue gas desulfurization process reaches over 95 percent.
The mainstream installation method in the limestone-gypsum wet flue gas desulfurization process is to install a glass electrode on a branch pipeline of a gypsum discharge pump outlet return absorption tower, and the glass electrode is immersed in the slurry to be detected, but the problem that the glass electrode is easy to damage is existed due to the thin permeable membrane of the glass electrode and the abrasion of gypsum crystal particles of the gypsum slurry, and the service life of the glass electrode is less than 3 months under general conditions.
The utility model discloses it is not enough to solve prior art and research and propose.
[ Utility model ] content
The utility model aims at overcoming above-mentioned prior art's shortcoming, providing a PH value measurement system that uses on desulfurization absorption tower, real-time measurement absorption tower PH value data to can effectively prolong the life of glass electrode.
The utility model discloses can realize through following technical scheme:
the utility model discloses a PH value measurement system who uses on desulfurization absorption tower contains the absorption tower, the absorption tower below is fixed with the contact tube with absorption tower internal connection, the contact tube level is fixed on aforementioned absorption tower, be fixed with the import valve on the contact tube, the connecting pipe of the terminal fixedly connected with vertical direction of contact tube, the terminal fixedly connected with of connecting pipe measures the pipe, measure pipe horizontal installation on the connecting pipe, measure inside being fixed with two glass electrodes of pipe, two the PH meter secondary table that glass electrode passing signal line connection corresponds, it is provided with the outlet valve to measure the pipe end, it still is fixed with the discharge pipe that links to each other with waste liquid collection device to measure the pipe end, the vertical downward setting of discharge pipe. Through the contact tube, connecting pipe and measuring catheter form the zigzag sampling tube, the glass electrode sets up on the horizontal measurement pipe of contact tube below, when the measuring fluid enters into the measuring catheter of below behind contact tube and the connecting pipe, need to change and get into the measuring catheter after twice directions, can effectively reduce the flow velocity that the measuring fluid passes through glass electrode department, can effectively prolong the life of glass electrode, and through setting up two glass electrodes and two PH meter secondary tables, can carry out real time monitoring to the measuring fluid, avoid the unable measuring problem of PH value to take place after single measuring electrode wearing and tearing, and can open 30% mode with the outlet valve through the inlet valve is wide open, form throttle effect, slow down the velocity of flow of thick liquid through glass electrode in the measuring catheter.
Compared with the prior art, the utility model has the advantages that:
1. through contact tube, connecting pipe and measurement pipe formation zigzag sampling tube, on the horizontal measurement pipe of glass electrode setting contact tube below, when the measurement liquid enters into the measurement pipe of below after passing through contact tube and connecting pipe, need to change and get into the measurement pipe after twice directions, can effectively reduce the flow velocity that the measurement liquid passes through glass electrode department, effectively prolong the life of glass electrode.
2. Through setting up two glass electrodes and two PH meter secondary tables, can carry out real time monitoring to measuring fluid, avoid single measuring electrode wearing and tearing back unable measuring problem of PH value to take place.
3. The throttling effect can be formed by fully opening the inlet valve and opening the outlet valve by 30 percent, the flow speed of the slurry in the measuring conduit flowing through the glass electrode is reduced, and the service life of the glass electrode is further prolonged.
