Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, now control illustrates
Specific embodiment of the present utility model.
A kind of desulfurization slurry PH meter protection device of the present utility model, in its preferred embodiment, desulfurization slurry PH meters
Protection device includes buffer pool casing 1, and the side of the buffer pool casing 1 is provided with injection point 2, serum outlet 3 and sewage draining exit
4；Its top is provided with to install the electrode installing port 5 of PH electrodes；The position of the injection point 2 and sewage draining exit 4 is less than described
Serum outlet 3；The position of the sewage draining exit 4 is less than or equal to the position of the injection point 2.Pass through the buffer pool casing 1, energy
The flow velocity of slurries is enough effectively reduced, greatly reduces slurries because of the too fast impact to electrode of flow velocity.Absorption tower slurries are from buffering
The inlet flange of pond bottom goes out into buffer pool, and exporting 3 flanges from upper slurry goes out discharge, former by the buffering of cabinet space
0.35MPa or so slurry pressure meeting dramatic decrease, avoids and washes out PH ball electrodes bubble because slurry flow rate is big, pressure is high.It is slow
Rushing bottom of pond portion has blow-off line, can smoothly discharge the impurity in pipeline and deposition slurries during whole media flow.
Desulfurization slurry PH meters protection device as described above, in its preferred embodiment, the electrode installing port 5, slurries
Entrance 2, serum outlet 3 and sewage draining exit 4 are connecting flange structure.Using flange arrangement, enable to the connection of pipeline simpler
Singly and conveniently.
Desulfurization slurry PH meters protection device as described above, in its preferred embodiment, it is provided with the buffer pool casing 1
Cooling water pipe 6.There is cooling water pipe 6 inside buffer pool, it is interior to be full of cooling water, slurries cooling can be played a part of, made at PH electrodes
In in normal operating temperature range, the degree of accuracy of measurement is improved.
Desulfurization slurry PH meter protection devices as described above, wherein, the cooling water pipe 6 is spiral helicine pipeline.Pass through
Spiral helicine cooling water pipe 6 can be cooled down preferably to slurries, protect PH electrodes.
Desulfurization slurry PH meter protection devices as described above, wherein, the top of the buffer pool casing 1 is provided with two electrodes
Installing port 5.2 PH electrodes installing ports 5 are provided with, in actual use, a measurement can be selected, a comparison, also may be used
