Abstract
The utility model belongs to the technical field of the installation of a monitoring instrument in the desulfurization technique, relating to a pH meter measuring device with a flushing pipe. The pH meter measuring device comprises a technical short pipe and an installing branch pipe which is internally provided with a measuring electrode. The pH meter measuring device is characterized in that the installing branch pipe and the technical short pipe are connected into a whole and communicated with each other; an upstream inclined angle alpha is formed between the axle wire of the installing branch pipe and the axle wire of the technical short pipe; the downstream side of the measuring electrode is provided with the flushing pipe; and the flushing pipe is bended in the technical short pipe and leads a water outlet to be aligned to the end head of the measuring electrode. The pH meter measuring device has the benefits that the installing branch pipe is changed to be inclined towards the upstream side from originally and approximately being perpendicular to the technical short pipe, so that the pH meter measuring device leads the end head of the electrode to be back onto serous fluid rather than facing to the serous fluid, thereby reducing the wear of the measuring electrode so as to prolong the service life; with the arrangement of the flushing pipe, the pH meter measuring device periodically flushes the serous fluid residue adhered to the end head of the measuring electrode, thereby reducing the measuring error; and the pH meter measuring device is applicable to the plaster serous fluid with a certain abradability and adhesivity, and the like.
Description
Technical field
The invention belongs to sulfur removal technology measuring instrument field engineering field, relate to the architecture advances that the mounting pipe of pH meter is installed on circulation duct, relate in particular to a kind of two pH meter measurement mechanisms, be applicable to occasions such as having certain abrasiveness and adhering gypsum slurries with wash tub pipe.
Background technology
Usually, for guaranteeing the quality of desulfurizing byproduct gypsum, the absorption tower entoplasm liquid pool of sulfur removal technology must keep being fit to the solutions of weak acidity (pH=4.5-5.5) of elementary accessory substance (calcium sulfite) forced oxidation, therefore need carry out on-the-spot pH value and measure monitoring.PH meter is made up of potential electrode and installation arm thereof on circulation duct, arm is installed is connected by vertical installation of flange with the measured medium circulation duct, and the glass shell of potential electrode is clamped in the installation arm and the potential electrode termination is goed deep in the medium.Because electrode is to adopt redox principle to measure, so constantly carrying out along with measuring process, electrode self life-span also exhausts gradually, gypsum slurries has abrasiveness and adhesiveness in the absorption tower, its abrasiveness can cause shorten more the serviceable life of electrode, the adhesiveness of gypsum slurries particle then can cause the measuring error of pH value, influences real-time control measurement.
The utility model content
The purpose of this utility model is: a kind of pH meter measurement mechanism with wash tub pipe is provided, reduces the pH measuring error and prolong the serviceable life of pH potential electrode, reduce maintenance work and change number of times, promptly reduce use cost.
For achieving the above object, the technical scheme that adopts is: the pH meter measurement mechanism of band wash tub pipe, the installation arm that comprises technology short tube, built-in potential electrode, it is characterized in that: described installation arm fuses with described technology short tube, pipeline communicates, and be upstream direction tilt alpha angle between the axis of the axis of described installation arm and described technology short tube, downstream in described potential electrode is equipped with wash tub pipe, and wash tub pipe is crooked and make water delivering orifice aim at the termination of potential electrode in the technology short tube.
Described α angle is 60 °～70 °.
Place the potential electrode termination of installing in the arm concordant with technology short tube inwall.
When needing two pH meter potential electrode of installing, described technology short tube tube wall cocurrent and parallel is equipped with the installation arm of two built-in potential electrode.
The invention has the beneficial effects as follows: it is oblique by changing inclination upstream into approximately perpendicular to the technology short tube originally that arm is installed, can make electrode tip to a certain extent back to slurries like this, rather than in face of slurries, and the potential electrode termination is concordant with the process pipe inwall, has reduced the potential electrode end wear to increase the service life; The setting of wash tub pipe, the slurries residue that adheres on the periodic flushing pH meter potential electrode termination has reduced measuring error.Reached and can accurately measure, it is minimum that the degree of wear is reduced to, and prolongs the serviceable life of pH potential electrode, reduces the purpose of use cost.Be applicable to occasions such as having certain abrasiveness and adhering gypsum slurries.
