Background technology
The sulfurous gas in coal-fired flue-gas is generally removed using limestone-gypsum method at present, in sweetening process, pH value is
Adapted to by carrying out dynamic regulation to control lime stone feeding coal in desulfuration absorbing tower the need for slurries quality and technique change.
So the accurate monitoring and control of pH value is particularly important in desulphurization system.
In sweetening process, the pH value of lime stone slurry must be controlled in specified scope in desulfuration absorbing tower, too low meeting
Cause lime stone slurry absorbability to decline, influence desulfurized effect, in turn result in discharge beyond standards；The spray of too high desulfuration absorbing tower
System and serum recycle system are possible to produce the serious consequence of fouling and clogging, in some instances it may even be possible to cause desulphurization system to shut down.
Therefore need design it is a kind of maintain easily, stable pH value measurement apparatus.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of desulfuration absorbing tower pH value measurement apparatus, by correlation
Measuring instrument be changed to outdoor version, design is optimized to discharge tube, recovery pond is connected directly to, increase measurement sample tap,
It is easy to change pH electrodes online.Person works' amount, maintenance workload and the cost of overhaul can be reduced.
For up to above-mentioned purpose, the concrete technical scheme that the utility model is taken is：
A kind of desulfuration absorbing tower pH value measurement apparatus, including：
The drainage tube connected with the slurry pool of desulfuration absorbing tower；
A pole cup of outdoor is installed on, its top is provided with pH electrodes；Liquid of the installation site less than slurries in slurry pool
Face；
Connect a delivery pipe of the pole cup and drainage tube；
The transmitter being connected with the pH electrode signals, the output signal of the transmitter is exported to a distributed AC servo system
System (DCS).
Further, a delivery pipe of the connection pole cup is included, the end of the delivery pipe is connected to a slurries and returned
Receives pond.
Further, the delivery pipe is provided with a regulating valve.
Further, the delivery pipe is provided with a shut-off valve.
Further, the transmitter is CM442.
Further, the pole cup material is stainless steel.
Further, the pH number of electrodes is two.
Further, the pH electrodes model CPS11D.
Further, the transmitter is connected by signal cable with the pH electrode signals.
By taking above-mentioned technical proposal, slurries to be measured are led to the pole cup for being arranged in outdoor with pipeline, without work
Personnel often go the on-site maintenance of desulfuration absorbing tower workshop section, maintenance, can reduce person works' amount, maintenance workload and the cost of overhaul.
Also, the mode that pH electrodes are arranged in top can allow it to reduce the impact being subject to while fully contact with slurries, extend pH
In the life-span of electrode, the stability of measurement apparatus is improved, ensure that desulphurization system is safe and stable, Effec-tive Function.
