Description
Technical field
This utility model relates to electric power factory equipment metering field, particularly relates to a kind of desulfuration absorbing tower PH meter.
Background technology
Along with China's expanding economy, environmental problem is the most prominent, and in air pollution, power plant is the row of sulfur dioxide
Amplify family, reduce the discharge of sulfur dioxide, be the subject matter of power plant pollution improvement, domestic flue gas desulphurization system, mainly
Limestone-gypsum Wet Flue Gas Desulfurization Process technique is main, adds substantial amounts of limestone and carrys out sulfur dioxide absorption, absorb two in absorption tower
The calcium sulfite of generation, calcium sulfate after sulfur oxide, reach to remove the purpose of sulfur dioxide, and pH value and the density of absorption tower serosity are
The important monitoring index that desulphurization system is run, if serosity PH is too low, sulfur dioxide assimilation effect is poor, and desulfuration efficiency is low, if
PH is too high, and limestone utilization and gypsum purity are on the low side, are unfavorable for the carrying out of desulphurization reaction.If serum density is too low, then starch
In liquid, limestone and gypsum content are relatively low, and desulfuration efficiency is on the low side, and Gypsum Fibrosum moisture content is higher；If serum density is too high, the most not only set
It is bigger than normal that standby abrasion and system run power consumption, also results in the problem that desulfuration efficiency declines and Gypsum Fibrosum moisture content is higher, therefore PH number
Value calculates desulfurization work extremely important.
In PH measurement amount wet processing, because calcium sulfate, calcium sulfite is solidified as solid particle, and PH is counted life-time service
Abrasion can be caused, reduce service life.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of desulfuration absorbing tower PH meter so that PH meter can reduce
Coefficient of friction, improves the service life of PH meter.
Described a kind of desulfuration absorbing tower PH meter, including glass shell, is provided with glass bead in glass shell one end, at glass
Electrolyte to be measured it is filled with in glass ball.
Be provided with internal reference electrode in the centre position of glass shell inner space, reference electrode maintains a constant electricity
Position, as the comparison measuring various deviation current potentials.
A kind of optimal technical scheme, described reference electrode uses silver-silver oxide electrode as reference electrode.
Reference electrode is connected to electrode cable, and electrode cable outer layer covers insulating barrier, the electrode cable other end is provided with
Electrode plug, and it is provided with metal isolation cover in electrode plug outer end.
Being provided with glass electrode on glass bead, glass electrode is set up a hydrogen ion activity to measured solution and is occurred
The potential difference that change is made a response.The electrode sensitive to PH and reference electrode are placed in same solution, and just composition one is former
Battery, the current potential of this battery is glass electrode and the algebraical sum of reference electrode current potential.E battery=E reference+E glass, if warm
Spending constant, the current potential of this battery changes along with the PH of solution to be measured and changes.
Being connected to galvanometer on electrode plug, galvanometer is provided with signal amplifier, and electromotive force is amplified, and is exaggerated
Signal is shown by ammeter, and the degree of meter pointer deflection represents the intensity of its signal promoted, for the need on using
, the dial plate of PH ammeter is carved with corresponding PH numerical value, and digital pH meter is then directly with numerical monitor pH value.
Being provided with one layer of filter mantle on glass bead, filter mantle has dust-proof, the function of anti-particles collision, thus improves PH
In the service life of meter, filter mantle uses rigid plastics to make, filter mantle is provided with filtering holes.
The beneficial effects of the utility model are: this utility model one desulfuration absorbing tower PH counts, and structure is compact to design, use
