Point chemical reaction, allow the smooth crystalline forming of gypsum slurries in desulphurization system.The accuracy that pH value is measured
Directly affect whole desulphurization system safety, economical operation.At present, existing measurement apparatus due to limestone,
Gypsum slurries contains chloride ion and easily fouling, cause pH electrode is washed away, wear and tear the most serious.Meanwhile,
PH meter also occurs in that in terms of measurement measured value drift is big, measures the problems such as inaccurate.
Utility model content
For weak point present in the problems referred to above, this utility model provides a kind of simple in construction, minimizing
Wear and tear and ensure the desulfurization pipeline slurry pH value measurement apparatus of desulphurization system stable operation.
For achieving the above object, this utility model provides a kind of desulfurization pipeline slurry pH value measurement apparatus, bag
Including pH meter, stop valve, sampling line and slurry pipe line, described sampling line is vertical with described slurry pipe line
Connecting, and described sampling line and described slurry pipe line communicate, described pH meter is arranged on described sampling line
On, one end of described pH meter is through described sampling line and stretches in described slurry pipe line, described probe tube
Road is provided with stop valve, described stop valve be fixed on described sampling line by flange and with described pH meter
The other end connect.
Improve further as this utility model, described stop valve is fixed with a pH flange, institute
State sampling line and be fixed with the 2nd pH flange near one end of described stop valve.
Improve further as this utility model, a described pH flange and described 2nd pH interface
Flange is bolted to connection.
Improve further as this utility model, a described pH flange and described 2nd pH interface
Flange gasket it is provided with between flange.
Improving further as this utility model, described 2nd pH flange is apart from described slurry pipe line
Distance is 50mm.
The beneficial effects of the utility model are:
1, slurry pH value is directly measured on pipeline, is not required to separately set the casing of the caching serosity of sampling and measuring,
Occupied ground space is little, has saved space, and this device is installed simple, reduces the life of equipment
Producing cost, operation is convenient, is not susceptible to fault, and operation maintenance is convenient；
2, the pH electrode of pH meter is inserted directly in slurry pipe line, it is ensured that pH measured value accurately in real time
Property；
3, to stretch into the length of serosity pipeline shorter for pH electrode, therefore alleviates serosity and washes away pH electrode,
Extend the life-span using pH meter；
4, stop valve scalable slurry stream is set, decrease serosity pipeline and pH meter and measure the mill of electrode
Damage.
Accompanying drawing explanation

Detailed description of the invention
As it is shown in figure 1, a kind of desulfurization pipeline slurry pH value measurement apparatus of this utility model embodiment, bag
Include pH meter 4, stop valve 5, sampling line 6 and slurry pipe line 7, sampling line 6 and slurry pipe line 7
Vertically connecting, and sampling line 6 and slurry pipe line 7 communicate, pH meter 4 is arranged on sampling line 6,
One end of pH meter 4 is through sampling line 6 and stretches in slurry pipe line 7, sampling line 6 is additionally provided with and cuts
Only valve 5, stop valve 5 is fixed with a pH flange 1, and sampling line 6 is near stop valve 5
One end is fixed with the 2nd pH flange 2, and stop valve 5 is by a pH flange 1 and the 2nd pH
Flange 2 is fixed on sampling line 6 and is connected with the other end of pH meter 4.Wherein, a pH
Flange 1 and the 2nd pH flange 2 connect pH flange 1 He by bolt 3 is fixing
It is provided with flange gasket 8 between 2nd pH flange 2.2nd pH flange 2 is apart from slurry pipe
The distance on road 7 is 50mm.
Time specifically used: absorption tower serosity flows out from slurry pool, through slurry pipe line 7 and sampling line 6,
Serosity contacts with the pH electrode of pH meter, can measure the pH value of serosity.Serosity of the present utility model
