Embodiment Construction

[0019] Attached below figure 1 attached figure 2 And attached figure 2 and Examples further describe the present invention; the present embodiment is implemented under the premise of the technical solution of the present invention, and detailed implementation is provided, but the protection scope of the present invention is not limited to the following examples.

[0020] Such as figure 1 with figure 2 As shown, the pH value sampling system 100 for desulfurization liquid with clarified slurry and anti-slurry clogging is composed of two parts: a pH value sampling device 50 and a pH value detection device 51 . Wherein, its pH value sampling device 50 includes a container cover 1 , an upper section 2 and a lower section 3 . The profile of its upper part 2 is barrel-shaped, the profile of its lower part 3 is inverted conical, and the container cover 1 is disc-shaped, and they are all made of metal materials. The upper section 2 and the lower section 3 are sequentially conne...

Abstract

A desulfurization liquid pH value sampling system capable of clarifying slurry and preventing slurry plugging belongs to the field of environment-friendly measurement instruments. Different from the prior art, a pH value meter is arranged in the pH value sampling system rather than putting an electrode of the value meter at a routine test position, so that the electrode of pH value meter avoids contact with a desulfurization slurry or contacts the desulfurization slurry as less as possible during a sampling process. Therefore, the system can prevent pollution or wrapping of the electrode of the pH meter by desulfurization slurry, extend the verification period of the pH meter and prolong the service life. A slurry plugging remover is made of a metal pipe; the inner wall surface of the pipe is subjected to grinding and polishing; the side wall of the pipe is provided with more than 2 inclined holes having a 100 DEG-170 DEG angle with a side of normal of the pipe; the inclined holes are through holes; and the surface of the hole wall is subjected to grinding and polishing. Usually, the system is fixed on a supporting frame, and the supporting frame is fixed in a casket container of the sampling device for usage.

Description

technical field [0001] The invention relates to a pH value sampling system for boiler exhaust gas desulfurization liquid, in particular to a pH value sampling system for boiler exhaust gas desulfurization liquid with multiple functions such as desulfurization liquid precipitation clarification and anti-slurry blockage, which belongs to the field of environmental protection Measuring instrument technical field. It can not only timely sample the pH value of the boiler exhaust gas desulfurization liquid, realize continuous, stable and accurate measurement of the pH value, but also reduce operating costs, reduce the burden on operators, and prolong the service life of the pH meter. Background technique [0002] At present, boiler flue gas desulfurization and related measuring instrument technology have become one of the hot research topics in the world. As we all know, the PH value of the desulfurization system is a key parameter in the operation of the boiler exhaust desulfuri...
