Abstract
The utility model discloses a desulfurizing tower pH value online test device, include: test container and PH meter, PH instrumentation volume doctor solution pH value is installed on the test container, the test container for storing the doctor solution, being connected with inlet pipe between entry and the desulfurizing tower, the exit linkage has a export pipeline who is used for discharging the doctor solution, the last valve that is provided with of inlet pipe. The utility model provides a desulfurizing tower pH value online test device, the doctor solution in the desulfurizing tower are in inlet pipe gets into the test container, and through the measuration pH value of in examination container doctor solution of PH instrumentation, doctor solution in the test container is discharged through export pipeline, because the doctor solution in the test container is in flow state, PH meter department can not deposit debris such as lime and influence PH instrumentation magnitude to make the measured value more accurate, and prolonged the life of PH meter.
Description
Technical field
This utility model is related to gypsum board manufacture technology, especially a kind of desulfurizing tower ph value online testing device.
Background technology
Desulfurizing tower mainly enters to pass through to the flue gas in gypsum board manufacturing process doctor solution desulfurization process, outside the flue gas after process
Row, after doctor solution is using a period of time, ph value can reduce, it usually needs adds such as Calcium Carbonate or sodium hydroxide in doctor solution
Etc. basic species, to proceed desulphurization reaction, using the ph value of ph measurement amount doctor solution.
But ph meter by Pipe installing on desulfurizing tower after, because the doctor solution in pipeline does not flow, time length
Calx will precipitate and be gathered in ph meter, causes numerical value to be forbidden；Often make ph meter failure, even damage it is impossible to accurately anti-
Feedback ph value, needs often to change, causes resource and the waste of manpower.
Utility model content
This utility model provides a kind of desulfurizing tower ph value online testing device, is used for overcoming defect of the prior art, surveys
Amount is accurate, the service life of extended testing system device, reduces and produces and operation cost.
This utility model provides a kind of desulfurizing tower ph value online testing device, comprising:
Ph counts, and measures doctor solution ph value, is arranged on test container；
Described test container, for storing doctor solution, is connected with inlet duct, outlet is connected between entrance and desulfurizing tower
For discharging the outlet conduit of doctor solution, described inlet duct is provided with valve.
Wherein, described entrance is arranged on described test container top, and described outlet is arranged on described test container bottom.
Further, described test container is in cylinder.
Further, also include introducing the chute of sedimentation tank for the doctor solution discharging described outlet conduit, described
The discharge end of outlet conduit is located above described chute or is placed in described chute.
The desulfurizing tower ph value online testing device that this utility model provides, the doctor solution in desulfurizing tower enters through inlet duct
In test container, by the ph value of doctor solution in ph measurement amount test container, the doctor solution in test container is arranged through outlet conduit
Go out, because the doctor solution in test container is in flow regime, the debris such as Calx impact ph will not be precipitated at ph meter and measure value,
So that measured value is more accurate, and extend the service life of ph meter.
Brief description
The structural representation of the desulfurizing tower ph value online testing device that Fig. 1 provides for this utility model embodiment.
Specific embodiment
Referring to Fig. 1, this utility model embodiment provides a kind of desulfurizing tower ph value online testing device, and main inclusion test is held
Device 1 and ph meter 2, the top of test container 1 is provided with entrance, closes stream position from desulfurizing tower latter end and draws inlet duct 3, with test
The entrance of container 1 connects, for the doctor solution in desulfurizing tower 10 is introduced in test container 1, the middle and lower part setting of test container 1
There is outlet, exit is connected with outlet conduit 4, for deriving the doctor solution in test container 2, it is to avoid doctor solution is adding stone
After ash, the debris such as the Calx of precipitation are had to be gathered on ph meter, the accuracy of impact ph measurement amount.Test container 1 is in cylinder, side
Just make and clear up, certainly also can arrange in prism etc..
Ph meter 2 is arranged on test container 1, inside the measuring probe insertion test container 1 of ph meter 2, when there being desulfurization liquor stream
Enter when touching measuring probe in test container 1, ph meter 2 can measure the ph values of doctor solution, so of doctor solution absorption2Deng acid
Property gas more, ph value will be lower, and when ph value is low, desulfurized effect just substantially reduces to certain limit, is at this moment accomplished by adding
With doctor solution to lift the desulfurized effect of doctor solution in the alkaline matters such as Calx.
Valve 5 is provided with inlet duct 3 it is not necessary to measure during the ph value of doctor solution so that it may close valve 5, blocks
Passage between desulfurizing tower 10 and test container 1 entrance, does not have doctor solution to enter in test container 1, if necessary to measurement desulfurization
So that it may open valve 5 during the ph value of liquid, open the passage between desulfurizing tower 10 and test container 1 entrance, have doctor solution to enter
In test container 1, in order to lift the accuracy of measurement further, valve can be also provided with outlet conduit 4, so, in measurement
Stage closes valve on outlet conduit 4, stores a certain amount of doctor solution in container 1 to be tested, floods or contact ph meter enough
During measuring probe, turn off the valve 5 on inlet duct 3, measurement opens outlet conduit 4 upper valve goalkeeper's test container after finishing again
Arrange outside doctor solution in 1.Prevent in doctor solution flow process the unstable of test.Valve can adopt manually-operated gate, convenient operation.
Sedimentation tank can be transported to by chute 6 by the doctor solution of the outer row of outlet conduit 4, the doctor solution in sedimentation tank is beaten again
Enter in desulfurizing tower, recycle.Chute 6 is in u shape, may be provided at subsurface, also can be made by steel, chute 6 top
Opening towards outlet conduit discharge end 41.
