+When ubiquitous in the use scene of measuring " cut off the water and do not have a power failure ", to the waste of medicine and medicine degree of depth amination (amine poisoning) effect to survey sensor; And when " have a power failure do not cut off the water ", survey sensor is caused acid passivation effect without the water sample of basification.Above-mentioned two kinds of phenomenons all can make Na
+Measurement can't carry out, influence the reliable measuring data of Treatment of Industrial Water desalination quality.In the prior art, be ZL87203033 utility model patent instructions disclosed " sodion sample water PH electrolysis control detection device " such as the patent No.; The patent No. is " the little sodium instrument of industrial intelligent " of ZL94226645.5 utility model patent instructions report; The patent No. is " agent of industrial sodium degree " that ZL98236628.0 utility model patent instructions is introduced; And the patent No. is that ZL00212273.1 utility model patent instructions disclosed " sun bed Na ion concentration detector " and number of patent application are ZL03133971.9 patent of invention instructions disclosed " automatic rapid assay methods of trace sodion and determinator ", has above-mentioned technical matters too.
[summary of the invention] the utility model has remedied domestic and international similar instrument deficiency in this respect, and its purpose is to provide the measurement mechanism of sodium ions content in a kind of novel water.
Concrete technical solution of the present utility model is:
The measurement mechanism of sodium ions content in a kind of novel water, comprise the measure and control instrument that is assemblied in the casing and potential electrode flow cell, the constant voltage water sample that is communicated with by pipeline detect cup, medicine amine case, air pump and solenoid valve, it is characterized in that said constant voltage water sample detects is provided with level switch in the cup, this level switch connects measure and control instrument; Measure and control instrument connects and control air pump and solenoid valve.This measurement mechanism can utilize and be arranged on the constant voltage water sample and detect level switch in the cup, according to the different operating modes that measure and control instrument is determined, after software program control time-delay, sends command adapted thereto for air pump timing working and solenoid valve.
Above-mentioned potential electrode flow cell and constant voltage water sample detect between the cup and are connected with two-way electromagnetic valve by pipeline.
The constant voltage water sample of above-mentioned measurement mechanism detects between cup and the three-way solenoid valve and is connected with pipeline, is connected with pipeline between three-way solenoid valve and the drainage box.
Be provided with pNa electrode, pH electrode, three electrodes of temperature electrode T in the potential electrode flow cell of above-mentioned measurement mechanism.
Measurement mechanism provided by the utility model is with IT technology, mechanical drive, sensing technology, electronic surveying in the dynamo-electric observing and controlling composite measurement equipment of one. it can solve effectively carries out Na in the Treatment of Industrial Water desalting process
+When ubiquitous in the use scene of measuring " cut off the water and do not have a power failure ", to the waste of medicine and medicine degree of depth amination (amine poisoning) effect to survey sensor; And when " have a power failure do not cut off the water ", survey sensor is caused acid passivation effect without the water sample of basification.The IT program that this device adopts simultaneously realize to measured medium carry out regularly, quantitatively, the pre-service of definite value, to satisfy Na
+The sufficient and necessary condition of measuring.This device solves " having water not have " that industry spot exists, " have electricity anhydrous " and measurements brings to Na+ worry effectively, has more solved the difficult problem that the protection survey sensor is not damaged unintentionally, has saved the reliability and the degree of accuracy of a large amount of medicines, raising measurement data.
[description of drawings] Fig. 1 is the utility model example structure synoptic diagram.
Fig. 2 is the utility model embodiment observing and controlling schematic flow sheet.
In the accompanying drawing: 1, measure and control instrument; 2, potential electrode flow cell; 3, the constant voltage water sample detects cup; 4, medicine amine case; 5, air pump; 6, three-way solenoid valve F1; 7, two-way electromagnetic valve F2; 8, drainage box; 9, casing; 10～14, pipeline.
The course of work that [embodiment] introduced under the utility model specific embodiment and the different operating mode in detail below in conjunction with accompanying drawing is explained as follows:
When " when having water that electricity is arranged ": water sample through piping 10. advance three-way solenoid valve F1 6. in, this moment, F1 established by cable logical, water sample enters the constant voltage water sample through pipeline and detects in the A of cup in 3., when water level rises to overflow, 3. to measure and control instrument 1. middle level switch e sends instruction, 1. by after the software program control time-delay, 5. timing working and F1 close the instruction of (volume of water sample is determined) to send air pump. air pump 5. filtered air through pipeline squeeze into medicine amine case 4. in, amine gas being squeezed into the constant voltage water sample through pipeline again detects among the cup A 3., water sample is alkalized among the A, when pump work finishes, the two-way electromagnetic valve F2 unlatching of 7. switching on, aqueous sample stream through F2 7. enter the potential electrode flow cell 2. in, and the pNa electrode in flowing through 2. successively, the pH electrode, temperature electrode T, three electrodes detect the electrode potential corresponding respectively with water sample and be input to measure and control instrument 1. in, 1. in scm software to the Na of water sample
+Content carries out stable current potential and shows in the window that the outputting standard electric current is given peripheral hardware simultaneously in judging when Δ V≤1mV locking measurement data and being presented at 1., in the time of the locking measurement, 7. two-way electromagnetic valve F2 closes, three-way solenoid valve F1 is 6. open-minded, and water sample enters through pipeline , and this device circulation is measured.
When anhydrous " have electric ": three-way solenoid valve F1 is 6. open-minded, no water sample enters the constant voltage water sample and detects among the cup A 3., no e command signal, and measure and control instrument is 1. after regularly waiting for, still failing to receive e instruction then sends and closes F1 and 6. instruct, in order to avoid 6. long-time energising damages three-way solenoid valve F1, for preventing accident the phenomenon of water sample test leakage is arranged, 1. time opening F1 is 6. again after 6. closing valve F1 for measure and control instrument, move in circles, do not have the e instruction because there not being water sample, 5. air pump does not work, and medicine amine is not wasted.The water sample that electrode contacted can not be alkalized by the degree of depth, and guard electrode can not poisoned by amine, and be extended serviceable life.
When " when having water not have electricity ": 6. 10. water sample enter three-way solenoid valve F1 through pipeline, and F1 is energising and valve cuts out 6., aqueous sample stream through pipeline enter drainage box 8. in.Because there is not electricity, 1. measure and control instrument shuts down, water sample can't enter measuring cell 2. in.Avoid electrode to touch acidic liquid, guard electrode can be by acid passivation.
