Description
Technical field
The utility model is related to the measurement apparatus of slurries pH in absorption tower a kind of, applied to wet process of FGD（WFGD）System
In system, belong to the technical field of flue gas desulfurization processing equipment.
Background technology
The absorption tower serosity density measurement of conventional wet desulfurization installs pH meter or in gypsum discharge line using tower wall is absorbed
Upper setting pH meter.The drawbacks of both mounting means all have very big, tower wall installs pH meter and is unfavorable for repair and maintenance, extracts pH meter
When, slurries outer can spray；When pH meter is arranged on gypsum discharge line, because slurry flow rate is very fast, pH meter probe is easy to wear, and
Need to monitor pH value of absorption column due to continuous, gypsum excavationg pump will keep continuous operation.Therefore a kind of more preferable pH meter is needed to survey
Device is measured, can both facilitate operating maintenance, again can be with energy-saving, and the service life of pH meter is improved, therefore propose this practicality newly
Type.
Utility model content
To overcome the problem of existing pH meter is measured, the utility model provides a kind of pH on more scientific and reasonable absorption tower
Measurement apparatus, slurries are continuously run by pipeline self without gypsum excavationg pump, and energy-saving purpose can be achieved.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：
A kind of pH measurement apparatus on absorption tower, including be arranged on the pipeline of absorption tower bottom, described pipeline and be connected with
Isolating valve, described isolating valve, is connected with pH by adapter and measures tank, and the pH is measured and pH meter is connected with tank, and pH measurement tanks
Bottom be connected with pipeline, described pipeline access absorption tower melt pit.
Described pH measurement tanks include cylinder-shaped upper part and tapered lower portion, and the minimum diameter of tapered lower portion is more than the straight of pipeline
Footpath.
The cone angle of the tapered lower portion is more than 45 °.
The beneficial effects of the utility model are as follows：
Slurries enter pH measurement tanks by pipeline self in the pH measurement apparatus on the utility model absorption tower, absorption tower, by
Pipeline is much larger than in pH measurement tank diameters, flow velocity of the slurries in pH measures tank is substantially reduced, and pH meter is installed can keep away in this position
Exempt from abrasion, the service life of pH meter can be improved, due to pH measurement pot bottom it is tapered, can avoid slurries because flow velocity reduce and herein
Deposition, slurries are continuously run by pipeline self without gypsum excavationg pump, and energy-saving purpose can be achieved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein, 1 it is isolating valve, 2 be adapter, 3 be pH measurements tank, 31 be cylinder-shaped upper part, 32 be tapered lower portion, 4 is pH
Meter, 5 be interface tube, 6 be pipeline, 7 be absorption tower.
Embodiment
The utility model is further described with reference to specific embodiment, but protection domain of the present utility model is simultaneously
Not limited to this.
As shown in figure 1, the pH measurement apparatus on the utility model absorption tower, including it is arranged on the interface tube of the bottom of absorption tower 7
5, it is connected with isolating valve, 1 on interface tube 5, isolating valve, 1 is connected with pH by adapter 2 and measured is connected with pH on tank 3, pH measurement tanks 3
Meter 4, the pH for the slurries of absorption tower 7 is measured, and the bottom of pH measurement tanks 3 is connected with pipeline 6, the access absorption tower melt pit of pipeline 6.
PH measurement tanks 3 in the utility model include cylinder-shaped upper part 31 and tapered lower portion 32, the minimum of tapered lower portion 32
Diameter is more than the diameter of pipeline 6.
During work, isolating valve, 1 is opened, and slurries gravity flow enters pH measurement tanks 3 through adapter 2 in absorption tower 7, and slurries are measured in pH
Flow velocity reduction in tank 3, after being contacted with pH meter 4, it is gravity flow shape that pH meter 4, which measures slurries in the pH value of slurries, whole measurement process,
State, discharge pump operation without gypsum slurries.Slurry flow rate in the pH value determination in pH measurement tanks 3 of pH meter 4, pH measurement tanks 3
It is very low, the abrasion of pH meter 4 can be avoided.By realizing the energy-saving purpose of pH measurement process with upper type, and improve pH
The service life of meter.PH measurement tanks 4 bottom is tapered, can avoid gypsum slurries in the deposition of ttom of pipe.
Isolating valve, 1 in the utility model is cold isolating valve, 1, and is Hand-operated butterfly valve, and valve plate material is 1.4529 or equivalent
Material, at least resistance to 20000ppmCl-Corrosion, valve body material is carbon steel line with rubber.The material of adapter 2 be FRP, PP, PVC, carbon steel line with rubber,
1.4529 or same material is waited, at least resistance to 20000ppmCl-Corrosion.PH measurement tank 3 materials are FRP or carbon steel lining glass flake or carbon
Steel lining glue, bottom is pyramidal structure, and cone angle is more than 45 °, and pH meter is installed in side.
Above-described embodiment is only used for illustrating inventive concept of the present utility model, rather than to the utility model rights protection
Restriction, it is all using this design to the utility model carry out unsubstantiality change, protection model of the present utility model all should be fallen into
Enclose.
