The utility model mainly comprises a sodium meter body, a display and a single-board computer controlling part printer and an observation system, and the utility model is characterized in that a galvanostat is arranged in order to keeping the water level constant by an overflow pipe; a high resistance head makes use of the high resistance signal transformation plate to amplify and convert the signal in order to make the signal remotely transmitted and connected with the single-board computer controlling part. With adopting the domestic electric pole and making use of the single-board computer for multiple sampling, the utility model replaces the actual measuring curve with a plurality of straight-line equations, and the utility model can continuously measure the micro sodium values in the water sample exactly in an on-line mode.
Description
The utility model belongs to chemical analysis instrument, specifically a kind ofly is used for the continuous on-line measurement analytical instrument that Trace Sodium ion concentration in high purity water, demineralized water, distilled water and the steam is monitored in electric system and some chemical enterprise pharmaceuticals industries.
The instrument that is used at present detecting the Na ion concentration of water in the Water Treatment device mostly adopts import instrument, SLTD1800 type and the 1811 type Na ion concentration detectors produced as the U.S. upright imperial ORIONS difficult to understand company.Because inlet electrode is difficult for configuration, when instrument breaks down, change the accessory difficulty.Import instrument has certain requirement to monitoring on-the-spot environment and equipment in addition, and the throttling valve that adopts in the detector that routine Ao Lilong company produces must be 8～100 pounds/inch of certain hydraulic pressure
2, could use during flow velocity 25 ml/min, its electrode is linear to be required to be therefore to be difficult for straight line popularizing using.
The purpose of this utility model is: design a kind of production domesticization fully, adopt homemade electrode, the Na ion concentration check and analysis instrument that not influenced by environment, water level etc.
Accompanying drawing 1 is an overall schematic of the present utility model.
Accompanying drawing 3 is the utility model alkalization case synoptic diagram.
Accompanying drawing 4 is the utility model high resistant head synoptic diagram.
Accompanying drawing 5 is calibration maps of the present utility model.
Accompanying drawing 6 is workflow diagrams of the present utility model.
The utility model is achieved in that the little sodium instrument of being made up of Na meter body, demonstration and single card microcomputer control section, printer and monitoring system (monitoring system comprises: water inlet portion, electrode part, alkali adding tank and high resistant conversion portion) of industrial intelligent, it is characterized in that: galvanostat 8 is set in Na meter body 24 upper right sides, galvanostat 8 joins with sampling valve 9, and water inlet pipe 10 and overflow pipe 11 also are set on the galvanostat 8.Water inlet pipe 10 is drawn the back and is joined with filtrator 14 from galvanostat 8, again the silicone tube 18 that inserts in the alkali adding tank 7 by flowmeter 13.The end of overflow pipe 11 in galvanostat 8 is provided with height and equates that with permanent water level is high the other end picks out water box 15.On alkali adding tank 7 tops pole cup 17 is set, arranges temperature compensation electrode 6, PNa electrode 5, contrast electrode 4 and flowmeter 13, filtrator 14 on the pole cup 17.High resistant head 12 also is set on pole cup 17, and high resistant head 12 is provided with 7 core aviation sockets 19 and high resistant joint 20,21.At Na meter body 24 upper left quarters display panel and single card microcomputer control section 1 and printer 3 are housed.Temperature compensation electrode 6, PNa electrode 5, contrast electrode 4 connect with display panel and single card microcomputer control section 1 through 7 core aviation sockets 19 by the high resistant signal transducer in the high resistant head 12.The single card microcomputer control section connects with printer 3.For anti-interference high resistant head 12 adopts metal shell 29 shieldings.
The utility model is work like this: water sample enters galvanostat 8 by sampling valve 9 controls, enters pole cup 17 by water inlet pipe 10.The water that enters pole cup 17 divides two-way again, and a route bypass valve 16 enters water outlet box 15; Another road enters flowmeter 13 through filter 14, regulates the flow valve 23 on the flowmeter 13, can the desired flow value of control survey.The water that is come out by flowmeter enters the silicone tube 18 in the alkalization case 7, because the osmosis of silicone tube 18, the water ph value that flows out from silicone tube 18 improves, and flow through temperature compensation electrode 6, PNa electrode 5, contrast electrode 4 successively, enter water outlet box 15 at last, the electrode that is inserted in the pole cup will be surveyed the sodium signal all the time, and temperature signal is sent into high resistant head 12, the signal that high resistant head 12 is sent each electrode here is given single card microcomputer by cable 22 and is handled behind preliminary the amplification.Single card microcomputer stores the parameter that each sample introduction records according to the program of finishing, set up the plurality of sections straight-line equation then, replace the actual curve equation of electrode with the plurality of sections straight-line equation of setting up, thereby overcome electrode single-point or 2 demarcation, the error of bringing in the electrode curve process.The real work of electrode is curve A BCDE.If with 2 demarcation (no matter being AB or AE), one section straight line demarcating replaces the real work curve, to produce very big error, and reach the coordinate of A, B, C, D, E each point, set up four straight-line equation AB, BC, CD, DE by single card microcomputer then by multi-point calibration.Replace curve A BCDE with these four straight-line equations.Then the sodium value of Ce Lianging is more accurate.Sending display and printer 3 to show after the signal that single card microcomputer is sent high resistant head 12 here is accurately handled prints.
Design of the present utility model is domesticized its element fully and has been solved the gamma correction problem of homemade electrode.Its stability of flow.Adopt high resistant head 12 to make its on-site signal can grow distance and carry, solved long distance and carried problem of signal attenuation.In the same industry, reach leading domestic status through expert appraisal the utility model.
