Abstract
The utility model relates to a potential of hydrogen (PH) meter for an inlet pipeline of a pure terephthalic acid (PTA) sewage treatment device, belonging to the PTA sewage treatment device. The PH meter is simple in structure and is divided into a first chamber, a second chamber and a third chamber, wherein the first chamber is a water inlet chamber with the functions of buffering and cooling; the second chamber is a measurement chamber with the functions of storing water and protecting an electrode; and the third chamber is a water discharge chamber; due to the structure, the measurement accuracy is guaranteed effectively, and the service life of the PH meter is prolonged.
Description
Technical field
The utility model relates to a kind of PTA sewage-treatment plant source line to be counted with PH, belongs to the PTA sewage-treatment plant.
Background technology
In the PTA production process, can discharge a large amount of production wastes, if sanitary sewage directly is discharged in the physical environment, then can cause severe contamination, so the production waste that produces in the PTA production process is sent in the sewage disposal device mostly to environment.
In sewage disposal process; Need to use PH to count detection at any time sewage-treatment plant enter the mouth a continuous water and a pH value of cutting off the water supply, the measuring principle of original PH meter is directly PH to be counted electrode to insert in the sewer line and measure, still; Because the sewage in the sewer line has carried a lot of solid impurities secretly and temperature is very high; Electrode to the PH flowmeter sensor washes away greatly, electrode damage very fast (length can only use month), so; Not only influence the sewage measured value, and consumed a large amount of spare parts.
Summary of the invention
In view of the defective that prior art exists, the purpose of the utility model is to provide a kind of simple in structure, and the PTA sewage-treatment plant source line of long service life is counted with PH.
For realizing above-mentioned purpose, the technical solution that the utility model adopted:
A kind of PTA sewage-treatment plant source line is counted with PH; Comprise: sample valve, first chamber, dividing plate one, PH flowmeter sensor, PH meter electrode, second chamber, dividing plate two, drainpipe, blowoff valve; It is characterized in that: be partitioned into three chamber closed containers by dividing plate one and dividing plate two; From left to right be followed successively by first chamber, second chamber and the 3rd chamber.
The lower end of said first chamber is connected with sample valve.
Said sample valve is a normally open.
PH meter electrode is set in said second chamber, and PH meter electrode one end stretches in second chamber, and the other end of PH meter electrode is connected with the PH flowmeter sensor; The second chamber lower end also is provided with a blowoff valve, and its state is a normally off.
The lower end of said the 3rd chamber is provided with a drainpipe.
After adopting such scheme, compare with existing apparatus and the utlity model has following beneficial effect:
The utility model is simple in structure, is divided into first chamber, second chamber and the 3rd chamber; First chamber is an intake chamber, plays the effect of buffering and cooling; Second chamber is the effect that measuring chamber has water storage and guard electrode simultaneously; The 3rd chamber is a drip chamber; Such structure can guarantee measuring accuracy effectively, has prolonged the serviceable life of PH meter simultaneously.

Fig. 1 is the utility model structural representation.
Among the figure: 1, sample valve, 2, first chamber, 3, dividing plate one, 4, PH flowmeter sensor, 5, PH counts electrode, 6, second chamber, 7, dividing plate two, 8, drainpipe, 9, blowoff valve, the 10, the 3rd chamber.
Embodiment
A kind of PTA sewage-treatment plant source line is counted with PH; Comprise: sample valve 1, first chamber 2, dividing plate 1, PH flowmeter sensor 4, PH meter electrode 5, second chamber, 6,7 dividing plates two, 8 drainpipes, 9 blowoff valves; It is characterized in that: be partitioned into three chamber closed containers by dividing plate 1 and dividing plate 27; From left to right be followed successively by first chamber 2, second chamber 6 and the 3rd chamber 10; The lower end of said first chamber 2 is connected with sample valve 1, and sample valve 1 is a normally open, and the sewage of required detection flow in first chamber 2 from sample valve 1, and first chamber 2 plays the effect of buffering cooling; PH meter electrode 5 is set in said second chamber 6; PH meter electrode 5 one ends stretch in second chamber 6, and the other end of PH meter electrode 5 is connected with PH flowmeter sensor 4, and second chamber 6 is responsible for measuring the pH value of sewage for measuring chamber; Second chamber 6 has the water storage effect simultaneously, is beneficial to protection PH meter electrode 5; Second chamber, 6 lower ends also are provided with a blowoff valve 9, and its state is a normally off, are convenient to the dirt that discharging regularly stockpiles; The lower end of said the 3rd chamber 10 is provided with a drainpipe 8, will measure water and emit.
