Abstract
The invention discloses a sampling device capable of reducing PH electrode pollution. The sampling device is characterized in that the top of a solid-liquid separator is connected to an adjustable overflow pipe; the adjustable overflow pipe is connected to a feed inlet of an overflow measuring tank by a flexible pipe; the top of the overflow measuring tank is connected to a PH measuring interface; and an inclined filtration orifice plate is connected between the PH measuring interface and the feed inlet. The sampling device can effectively prevent PH glass electrode wearing caused by a high-solid content liquid, reduce an easy-scaling solid-containing liquid deposited on the surface of a PH glass electrode, and improve the accuracy of PH measurement.
Description
Technical field
A kind of sampler according to the invention relates in particular to a kind of sampler of the PH of minimizing electrode fouling.
Background technology
Contain in the solid-liquid body pH value measuring process, pH value is relevant with liquid ions content and activity, and what have nothing to do with solid content.The PH electrode is to process membrane electrode by glass film, is prone to fragmentation, and electrode surface pressure, dirt, the degree of wear are to measuring influence greatly.High solids liquid is when flow velocity is higher, and solid particle is bigger to the wearing and tearing of PH glass electrode, influences the life-span of electrode and the accuracy that PH measures.Easy fouling contains solid particle in the solid-liquid body easily in the deposition on PH glass electrode surface, influence the accuracy of PH measurement.Coagulation is the conventional steps in water treatment and the wastewater treatment process; PH value is one of principal element that influences coagulation effect; Glassware for drinking water in the water treatment procedure behind the interpolation coagulant has deposition and fouling tendency tendency; Flocculate in the coagulation process is prone to form the scale deposition thing on the glass electrode surface, influences PH and measures.In the limestone-gypsum flue gas desulfurizing process, the desulfurization slurry pH value is the controlled factor of desulfuration efficiency.Solid content reaches about 15% in the desulfurization slurry, currently all directly with glass electrode the slurries pH value is measured, and the wearing and tearing of glass electrode are big, and electrode life is short, measures poor accuracy.
Summary of the invention
The object of the present invention is to provide a kind of sampler of the PH of minimizing electrode fouling, can prevent effectively that height from containing the wearing and tearing of solid-liquid body to the PH glass electrode, reduce easy fouling and contain the deposition of solid-liquid body, improve the accuracy that PH measures on PH glass electrode surface.
The present invention realizes like this; It comprises that equipment for separating liquid from solid, scalable run-down pipe, overflow measuring cell, PH measure interface, orifice filter; The top that it is characterized in that equipment for separating liquid from solid is connected with the scalable run-down pipe; The scalable run-down pipe is through the charging aperture of flexible pipe access overflow measuring cell, and the upper end of said overflow measuring cell is connected with PH and measures interface, and said PH measures the orifice filter that is connected with inclination between interface and the charging aperture.
A kind of being used to of the present invention reduces the sampler that the PH potential electrode is polluted, and comprises at least one equipment for separating liquid from solid and overflow measuring cell.Equipment for separating liquid from solid adopts principle of hydraulic cyclone to realize Separation of Solid and Liquid, and tripping device is equipped with the scalable run-down pipe, regulates solid content in the overflowing liquid through regulating the run-down pipe insertion depth.The overflow measuring cell comprises that run-off, PH measure interface and self-filtering mesh plate.
The effect that application of the present invention can reach is:
The solid-liquid cyclone separation device effectively reduces solids content in the overflowing liquid, and especially big solid content of particle diameter is avoided the wearing and tearing of bulky grain to glass electrode.
The solid-liquid cyclone separation device effectively reduces solids content in the overflowing liquid, avoids being prone to deposition fouling solid particle and deposits in glass electrode, and accuracy is measured in influence.
The solid-liquid cyclone separation device is equipped with the scalable run-down pipe, can regulate the insertion depth of run-down pipe according to the rerum natura of solid particle in the fluid to be measured, reaches the few purpose of solid content in the overflowing liquid.
Overflow measuring cell set inside angle-inserting type orifice filter can filter overflowing liquid, and solids content is to Effect on Electrode in the further minimizing measurement liquid.The angle-inserting type orifice filter is easy to dismounting, and it is convenient to change flushing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
In the drawings, 1, equipment for separating liquid from solid 2, overflow measuring cell 3, water inlet pipe 4, underflow opening 5, scalable run-down pipe 6, flexible pipe 7, orifice filter 8, PH measure interface 9, leakage fluid dram 10, sewage draining exit 11, charging aperture.
Embodiment
Fig. 1 is a structural representation of the present invention.As shown in the figure; The top of equipment for separating liquid from solid 1 is connected with scalable run-down pipe 5; Scalable run-down pipe 5 inserts the charging aperture 11 of overflow measuring cell 2 through flexible pipe 6; The upper end of said overflow measuring cell 2 is connected with PH and measures interface 8, and said PH measures the orifice filter 7 that is connected with inclination between interface 8 and the charging aperture 11.During use, band is pressed and is contained the solid-liquid body through water inlet pipe 3 tangentials entering equipment for separating liquid from solid 1, in equipment for separating liquid from solid 1, produces the high speed rotating flow field, and at centrifugal action, the solid particle that density is big forms the concentrated phase slurries and discharges from underflow opening 4, forms underflow liquid.The solid particle that density is little is formed centrally the interior eddy current that moves upward in solid separating device 1, the dilute phase slurries are discharged from scalable run-down pipe 5, form overflowing liquid.Overflowing liquid gets into overflow measuring cell 2 through flexible pipe 6, and 7 pairs of overflowing liquids of the self-filtering orifice plate of overflow measuring cell filter, and the PH electrode is measured 8 pairs of overflowing liquids of interface through PH and measured.Liquid after the measurement is discharged from leakage fluid dram 9, fails solid matter through self-filtering orifice plate 7 in the overflow measuring cell, regularly discharges through sewage draining exit 10.
