Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the online sodium table water sample alkalization measurement mechanism of the utility model one embodiment.
Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1, the online sodium table water sample alkalization measurement mechanism of the utility model one embodiment, is applicable to the system (demineralized water production system) that gap is run, measures the sodium ions content of cation bed exit water sample.This online sodium table water sample alkalization measurement mechanism can comprise online sodium table 10, the reagent bottle 20 of diisopropylamine and pneumatic pump 30 are housed.Online sodium table 10 for being arranged on cation bed exit, to introduce the water sample in cation bed exit; The diisopropylamine steam of reagent bottle 20 is drawn in the flow cell 11 of online sodium table 10 by pneumatic pump 30, and to alkalize to water sample, the water sample after alkalization is measured by online sodium table 10 and drawn wherein sodium ions content.
Online sodium table 10 comprises airtight flow cell 11, transmitter 12 and is connected with transmitter 12 and is plugged on sodium electrode 13, contrast electrode 14 and the temperature electrode 15 in flow cell 11.Flow cell 11 for hold from cation bed exit draw water sample, water sample flow cell 11 in through alkalize after measure again.Flow cell 11 can be connected with the inlet channel 16 passed through for water sample, the cation bed exit water sample of drawing to be circulated pond 11 by this inlet channel 16.Inlet channel 16 is provided with valve 17, to control opening or the closedown of this inlet channel 16.Transmitter 12 is the display unit of online sodium table 10, is carried out changing and showing by the signal that sodium electrode 13, contrast electrode 14 and temperature electrode 15 measure in water sample.
In the measurement mechanism of the present embodiment, diisopropylamine is adopted to replace traditional ammoniacal liquor as the basifier of water sample.Diisopropylamine alkalization ability is comparatively strong in ammoniacal liquor, therefore only needs a small amount of diisopropylamine when water sample alkalizes.Further, diisopropylamine has strong volatility, and the steam therefore evaporated by diisopropylamine by pneumatic pump 30 is directly drawn in water sample and alkalizes to water sample, and can not introduce the ion as ammonium ion etc. disturbs sodion measurement.
Particularly, the inlet end of pneumatic pump 30 is connected with the first pipeline 31, and the outlet side of pneumatic pump 30 is connected with second pipe 32.The other end of the first pipeline 31 connects reagent bottle 20 and is positioned at the ullage of reagent bottle 20, to be run the steam extracting diisopropylamine and evaporate by pneumatic pump 30.The other end of second pipe 32 connects flow cell 11 and is positioned at below the liquid level of flow cell 11, directly to be joined in water sample by diisopropylamine steam, reaches alkalization water sample and beating action simultaneously.Preferably, the first pipeline 31 and second pipe 32 adopt nylon tube, have alkali resistance and ageing-resistant characteristic.This first pipeline 31 and second pipe 32 are preferably detachably connected between pneumatic pump 30 and reagent bottle 20, between pneumatic pump 30 and flow cell 11 respectively, thus at tempus intercalare, first pipeline 31 and second pipe 32 can be pulled down respectively on pneumatic pump 30 and reagent bottle 20, on pneumatic pump 30 and flow cell 11, install when needing again.
Further, this online sodium table water sample alkalization measurement mechanism also comprises the 3rd pipeline 21; 3rd pipeline 21 one end is plugged to below the liquid level of reagent bottle 20, other end connection extraneous air.3rd pipeline 21 can be used for inspection pneumatic pump 30 and whether has extracted diisopropylamine steam; When pneumatic pump 30 extracts, the 3rd pipeline 21 is positioned at one end below reagent bottle 20 liquid level if any bubble, then illustrate that pneumatic pump 30 extracts and has diisopropylamine steam.
Due to the strong volatility that diisopropylamine has, have a small amount of diisopropylamine and evaporate from water sample.The diisopropylamine evaporated for avoiding water sample distributes and works the mischief to human body or environment in flow cell 11, and this online sodium table 10 water sample alkalization measurement mechanism also comprises the amine mist absorption bottle 40 and the 4th pipeline 41 that are absorbed by the diisopropylamine evaporated.Diisopropylamine is organic solvent, and according to the principle that organic solvent mixes, amine mist absorption bottle 40 is equipped with Diluted Alcohol, for absorbing the diisopropylamine evaporated from water sample.One end of 4th pipeline 41 is plugged to below the liquid level of amine mist absorption bottle 40, the other end to be plugged in flow cell 11 and to be positioned at the ullage of flow cell 11, in flow cell 11, the diisopropylamine steam of ullage flow in amine mist absorption bottle 40 by the 4th pipeline 41, and is dissolved in Diluted Alcohol.4th pipeline 41 is preferably nylon tube.
In addition, bottom the flow cell 11 of online sodium table 10, be also connected with drainage pipeline 18, for water sample is discharged flow cell 11.This drainage pipeline 18 is provided with valve 19, for controlling opening or the closedown of drainage pipeline 18.
When this online sodium table water sample alkalization measurement mechanism uses, by inlet channel 16, the water sample in cation bed exit is entered in the flow cell 11 of online sodium table 10, close inlet channel by the valve 17 on inlet channel 16; Pneumatic pump 30 runs and is drawn in the water sample of flow cell 11 by the diisopropylamine steam of reagent bottle 20, is alkalized by water sample; The signal measured in water sample by sodium electrode 13, contrast electrode 14 and temperature electrode 15 carries out changing and showing by the transmitter 12 of online sodium table 10, thus can obtain the content of sodion in water sample.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
