Abstract
The invention provides a water quality analyzer capable of well detecting the existence/absence of a water sample, a reagent, the diluted water or other liquids at a low cost. By means of a temperature sensor (42, 53), the temperature of the liquid flowing into reactor, a measuring container and the like can be detected. Based on the temperature change of the liquid, a flowing state determination processing unit (102) judges the state of the flowing state of the liquid. When the liquid flows into a flowing part, the temperature of the flowing part changes greatly. However, when no liquid flows into the flowing part, the temperature does not change. Therefore, when the temperature of the flowing part does not change, it can be determined that no liquid flows into the flowing part.

Water Test Kits involved in the present invention has inflow part, temperature sensor and flows into state determination processing unit.Water sample, reagent or dilution water individually or flow into described inflow part as mixed liquor.The temperature of the liquid in described inflow part is detected by described temperature sensor.The change of the temperature that described inflow state determination processing unit is detected based on described temperature sensor, judges the inflow state of the liquid flowed in described inflow part.
According to such structure, it is possible to the temperature being entered the liquid in inflow part by temperature sensor convection current is detected, the inflow state based on its variations in temperature sample to flowing in inflow part judges.That is, when liquid flows in inflow part, there is relatively larger variation in the temperature of inflow part, and when liquid does not flow in inflow part, such variation will not occur.Therefore, in inflow part for liquid time, it does not have when there is the such variations in temperature generally occurred, it is possible to determine that for not flowing into the liquid of set amount in inflow part.
In this case, even if when liquid leaks in the way of the pipe arrangement connected with inflow part, it also is able to the presence or absence of liquid is detected, therefore compared with adopting structure as the sensors such as float sensor, it is possible to detect the presence or absence of the liquid such as water sample, reagent or dilution water well.Again, when the temperature sensor controlled required for being a timing by the temperature of inflow part is arranged in Water Test Kits from the beginning, owing to need not additionally arrange sensor, it is possible to detect the presence or absence of liquid at low cost.
Described inflow part can be the reactor making the composition in water sample react or the mensuration container of the reacted water sample being supplied in described reactor.
According to such structure, it is possible to the presence or absence being supplied to the liquid such as reactor or the mensuration water sample of container, reagent or dilution water is carried out good detection.Especially, in reactor or mensuration container, it is usually provided with and controls the temperature of inflow part to be the temperature sensor required for a timing, therefore by this temperature sensor of employing, it is possible to additionally do not arrange sensor, it is possible to detect the presence or absence of liquid at low cost.
Described inflow state determination processing unit is based on the change of the temperature detected by described temperature sensor within a certain period of time, the inflow state of the mixed liquor flowed in described inflow part is judged, described certain time is that the inlet time of the water sample to flow in described inflow part as mixed liquor, reagent and dilution water is for benchmark.
According to such structure, by the variations in temperature produced when mixed liquor flows in inflow part is detected, it is possible to the presence or absence of detection mixed liquor.Due to water sample, the mixed liquor inflow reactor of reagent and dilution water or measure in container when analyzing, therefore based on this inlet time for the variations in temperature in the certain time of benchmark, it is possible to detect the presence or absence of mixed liquor well.
Described inflow state determination processing unit can based on the change of the temperature detected by described temperature sensor within a certain period of time, the inflow state of the dilution water flowed in described inflow part is judged, described certain time is with the inlet time flowing into the dilution water in described inflow part individually for benchmark.
According to such structure, by the variations in temperature produced when dilution water flow enters in inflow part is detected, it is possible to the presence or absence of detection dilution water.Due to the dilution water inflow reactor individually or measure in container when cleaning, therefore based on this inlet time for the variations in temperature in the certain time of benchmark, it is possible to detect the presence or absence of dilution water well.
Described Water Test Kits can also have the result of determination based on described inflow state determination processing unit and notify abnormal abnormal notifier processes portion.
According to such structure, when there is not such variations in temperature of generally generation when in inflow part for liquid time, it is determined that for not flowing into the liquid of set amount in inflow part, it is possible to abnormal based on this result of determination notice.Therefore, it is possible to prevent situation about being analyzed under abnormality.

The common port of the first multiported valve is connected with the first port of the second multiported valve 2.The common port of the second multiported valve 2 is connected with syringe 3.Syringe 3 has such as cylinder 31 and plunger 32, by making plunger 32 displacement being inserted in cylinder 31, it is possible to carry out the attraction action to syringe 3 and from the discharging operation of syringe 3.
The water sample gathering and being placed on Water Test Kits in advance supplies the first port to the first multiported valve 1 off-line from water sample accumulation unit (not shown).Therefore, when making the first port of the first multiported valve 1 connect with common port and the first port of the second multiported valve 2 connects with common port, if carried out the attraction action of syringe 3, then can off-line by water sample supply to syringe 3.
The second port that water sample is supplied to the first multiported valve 1 from water sample supply sources such as drainage equipment online by pipe arrangement.Therefore, when the second port making the first multiported valve 1 connects with common port and makes the first port of the second multiported valve 2 connect with common port, if carried out the attraction action of syringe 3, then can online by water sample supply to syringe 3.Now, the sample supplied online, after the pre-treatment specified by such as pretreating device (not shown), is supplied to the second port.
Accumulation has the reagent accumulation unit 21～26 of different reagent to be connected to the second～the 7th port of the second multiported valve 2.By making some ports of these ports connect with common port and carrying out the attraction action of syringe 3, it is possible to by reagent supply to syringe 3 and make reagent mix with water sample.As being accumulated in the reagent of each reagent accumulation unit 21～26, sulphuric acid, molybdic acid, ascorbic acid (acid of ア ス U Le PVC Application), sodium hydroxide, peroxide and hydrochloric acid etc. can have been illustrated, but it is not limited to this, it is possible to accumulate other arbitrary reagent in reagent accumulation unit 21～26.
Dilution water accumulation unit 12 is connected to the 6th port of the first multiported valve 1.When water sample is diluted, cleaning reactor 4 or measure container 5 time etc. use dilution water be accumulated in dilution water accumulation unit 12.When the 6th port making the first multiported valve 1 connects with common port and makes the first port of the second multiported valve 2 connect with common port, attraction action if carried out syringe 3, it is possible to diluent is supplied to syringe 3 and makes diluent mix with water sample.
So, by suitably switching the first multiported valve 1 and the second multiported valve 2, and the attraction action of syringe 3 is carried out, it is possible in syringe 3, generate the mixed liquor of water sample, reagent and dilution water.Mixed liquor in syringe 3 is stirred by the driving of mixing pump 6.Reactor 4 is connected to the 4th port of the first multiported valve 1, when making the 4th port connect with common port and to make the first port of the second multiported valve 2 connect with common port, if carried out the discharging operation of syringe 3, then the mixed liquor in syringe 3 can be supplied to reactor 4.
Reactor 4 is the inflow part that water sample, reagent and dilution water flow into as mixed liquor, by from light source 41 to internal mixed liquor irradiation ultraviolet radiation, make the various compositions oxidations such as the nitride in water sample, phosphide.As light source 41, for instance low pressure mercury lamp can be adopted, but be not limited to this, it is possible to adopt the other light sources 41 such as excimer laser, deuterium lamp, xenon lamp or Hg-Zn-Pb lamp.Liquid in reactor 4 is heated by such as heater (not shown).Now, it is controlled based on the detection signal from the temperature sensor 42 (with reference to Fig. 2) that the temperature of the liquid in reactor 4 is detected, so that the temperature of liquid becomes predetermined temperature.

The liquid measured in container 5 is discharged to outside device as waste liquid.Again, about the liquid in reactor 4, the driving also by excavationg pump 7 is discharged to outside device as waste liquid.The fifth port of the first multiported valve 1 is connected with waste liquid by the second switching valve 9 with discharging ground and draining discharge.Second switching valve 9 can by switching one of them liquid in device optionally exports to waste liquid discharge or in draining discharge ground of stream.
Fig. 2 is the block diagram of the electrical structure of the Water Test Kits illustrating Fig. 1.The action of this Water Test Kits is such as controlled by the control portion 100 comprising CPU (CPU (CentralProcessingUnit)).Except above-mentioned each parts, control portion 100 also electrically connect with storage part 200 and display part 300 etc..
Control portion 100 is used as analysis and Control portion 101, inflow state determination processing unit 102 and abnormal notifier processes portion 103 etc. by CPU execution program and plays a role.Storage part 200 is the structure comprising such as RAM (random access memory (RandomAccessMemory)), ROM (read only memory (ReadOnlyMemory)) or hard disk, and storage has the data required for the action of Water Test Kits.Display part 300 is such as made up of liquid crystal display, and the analysis result of water sample, other necessary information are displayed by it.
The action of above-mentioned each parts, based on the analysis program being stored in storage part 200, is controlled by analysis and Control portion 101, and what thus carry out water sample analyzes required process.Specifically, the first multiported valve 1 and the second multiported valve 2 are switched over by analysis and Control portion 101, and make syringe 3, mixing pump 6, excavationg pump the 7, first switching valve 8 and second cut for the suitable action of valve 9.Thus, water sample, reagent or dilution water individually or as mixed liquor be transported to reactor 4, measure container 5, other supply destination (include waste liquid discharge ground or draining discharge ground.).
Analyze program package containing with the time switching the first multiported valve 1 or the second multiported valve 2, make syringe 3, mixing pump 6, excavationg pump 7, first switch relevant information movement time of each parts such as time of valve 8 or the second switching valve 9 action.Can impose a condition according to the temperature of operator's liquid set in advance, quantity delivered etc. these movement times and determine.
Inflow state determination processing unit 102 carries out for judging the process to reactor 4, the inflow state of the liquid measuring container 5.Specifically, based on from the temperature sensor 42 that the temperature of liquid in reactor 4 is detected, detection signal to the temperature sensor 53 etc. that the temperature of liquid measured in container 5 detects, monitor the variations in temperature of these liquid by flowing into state determination processing unit 102.In liquid inflow reactor 4 or when measuring in container 5, can there is relatively larger variation in the temperature of reactor 4 or mensuration container 5, and do not have in inflow reactor 4 or when measuring in container 5 at liquid, and such variation will not occur.Therefore, in reactor 4 or in mensuration container 5 for liquid time, it does not have when there is the such variations in temperature generally occurred, it is possible to determine that reactor 4 is interior or measures the liquid not flowing into set amount in container 5.
In this case, even if leaking under such circumstances at liquid in the way of the pipe arrangement connected with reactor 4, mensuration container 5, it also is able to the presence or absence of liquid is detected, therefore compared with adopting structure as the sensors such as float sensor, it is possible to detect the presence or absence of the liquid such as water sample, reagent or dilution water well.Again, as in the present embodiment, at reactor 4, measure in container 5, it is usually provided with and controls the temperature of inflow part to be the temperature sensor 42,53 required for a timing, therefore the words of this temperature sensor 42,53 are adopted, sensor can not be additionally set, it is possible to detects the presence or absence of liquid at low cost.
It addition, whether occur above-mentioned " the such variations in temperature generally occurred " can be judged by various states.Such as, the difference (amount of change) of the maxima and minima of temperature within a certain period of time is below threshold value, the gradient of variations in temperature within a certain period of time is below threshold value or the situation of temperature that is not reaching to envision according to the variations in temperature in certain time inferior, can interpolate that as not there is the such variations in temperature generally occurred, it is possible to be judged in reactor 4 or measure the liquid not flowing into set amount in container 5.
Above-mentioned certain time inflow reactor 4, time of measuring in the inflow part such as container 5 should determine ratio more preferably for benchmark with liquid.Liquid should flow into the time in inflow part and can judge based on the analysis program being stored in storage part 200.Namely, it is possible to based on the information that the movement time of each parts comprised with analysis program is relevant, the time that liquid should be flowed in inflow part is predicted.Can with this time for benchmark, for instance with the certain time started from this time or the certain time such form comprising this time, the period when inflow state to the liquid flowing to inflow part that sets judges.
For example, it is possible to using the inlet time as the water sample in the inflow part such as mixed liquor inflow reactor 4 or mensuration container 5, reagent and dilution water for benchmark, set above-mentioned certain time.In this case, utilize temperature sensor 42,53 to detect the variations in temperature produced when mixed liquor within this certain time flows in inflow part, it is possible to the presence or absence of mixed liquor is detected.That is, in reactor 4 or mensuration container 5, owing to flowing into the mixed liquor of water sample, reagent and dilution water when analyzing, it is possible to based on this inlet time for the variations in temperature in the certain time of benchmark, the presence or absence of mixed liquor is carried out good detection.
But, the presence or absence of the mixed liquor being not limited in detection inflow part, it is also possible to individually the presence or absence of water sample, reagent or dilution water is detected.Such as, in cleaning reactor 4 or when measuring the inflow part such as container 5 etc., it is possible to individually flow into the dilution water in this inflow part inlet time for benchmark, set above-mentioned certain time.In this case, it is possible to the variations in temperature produced during by detecting dilution water within this certain time and individually flowing in inflow part, the presence or absence of dilution water is detected.That is, at reactor 4 or measure in container 5, owing to dilution water flows into individually when cleaning etc., it is possible to based on this inlet time for the variations in temperature in the certain time of benchmark, the presence or absence of dilution water being carried out good detection.
Abnormal notifier processes portion 103, based on the result of determination flowing into state determination processing unit 102, carries out for notifying abnormal process.Specifically, when being judged to that liquid does not flow in inflow part or when influx not met set amount by flowing into state determination processing unit 102, operator is notified by making this situation be shown in display part 300.
Thus, in inflow part for liquid time, it does not have when there is the such variations in temperature generally occurred, it is determined that for not flowing into the liquid of set amount in inflow part, it is possible to notify exception based on this result of determination.Accordingly it is possible to prevent be analyzed under abnormality.But, the notice in abnormal notifier processes portion 103 is not limited to display, it is also possible to be the structure undertaken by other the mode such as sound.
Fig. 3 A～Fig. 3 C is the figure of the variations in temperature illustrating the liquid in reactor 4.Fig. 3 A illustrates variations in temperature when water sample, reagent and dilution water are all normally supplied to reactor 4.Fig. 3 B illustrates that water sample is not by variations in temperature when in normal supply to reactor 4.Fig. 3 C illustrates that dilution water is not by variations in temperature when in normal supply to reactor 4.
As the period in liquid inflow reactor 4, have with the time that only dilution water flows into be benchmark certain period (dilution water flows into period T11, T14), with the time that the mixed liquor of water sample, reagent and dilution water flows into be benchmark certain period (mixed liquor inflow period T12, T13) etc..As shown in Figure 3A, when water sample, reagent and dilution water are all normally supplied to reactor 4, flowing at dilution water in period T11, T14 and mixed liquor inflow period T12, T13, all there is bigger variation in the temperature of the liquid in reactor 4.
On the other hand, when water sample is not normally supplied to reactor 4, as shown in Figure 3 B, period T12, T13 are flowed at mixed liquor, it does not have such variation shown in Fig. 3 A occurs.Again, when dilution water is not normally supplied to reactor 4, as shown in Figure 3 C, period T11, T14 are flowed at dilution water, it does not have such variation shown in Fig. 3 A occurs.So, when not there is the such variations in temperature generally occurred, it is possible to determine that be not normally flowed in reactor 4 for the liquid such as water sample, dilution water.
It addition, mixed liquor flows into period T12 makes the period in mixed liquor inflow reactor 4 in order to total nitrogen concentration is measured, the temperature of the mixed liquor in reactor 4 in total nitrogen concentration measures such as is set to 70 DEG C.Again, mixed liquor flows into period T13 and makes the period in mixed liquor inflow reactor 4 in order to total phosphorus concentration is measured, and the temperature of the mixed liquor in reactor 4 in total phosphorus concentration measures such as is set to 95 DEG C.On the other hand, dilution water flows into period T11, T14 and makes the period in dilution water inflow reactor 4 in order to reactor 4 is carried out.The temperature of the mixed liquor in reactor 4 can be adjusted to different temperature in total nitrogen concentration measures and in total phosphorus concentration mensuration as described above, it is also possible to is adjusted to identical temperature.
Fig. 4 A～Fig. 4 C is the figure of the variations in temperature illustrating the liquid measured in container 5.Fig. 4 A illustrates that water sample, reagent and dilution water are all by normally supply to variations in temperature when measuring in container 5.Fig. 4 B illustrates that water sample is not by normal supply to variations in temperature when measuring in container 5.Fig. 4 C illustrates that dilution water is not by normal supply to variations in temperature when measuring in container 5.
Flow into, as liquid, the period measured in container 5, have with the time that only dilution water flows into be benchmark certain period (dilution water flows into period T2l, T22, T24, T26), with the time that the mixed liquor of water sample, reagent and dilution water flows into be benchmark certain period (mixed liquor inflow period T23, T25) etc..As shown in Figure 4 A, when in water sample, reagent and dilution water are all by normally supply to mensuration container 5, flowing at dilution water in period T2l, T22, T24, T26 and mixed liquor inflow period T23, T25, all there is bigger variation in the temperature measuring the liquid in container 5.
On the other hand, when in water sample is not by normally supply to mensuration container 5, as shown in Figure 4 B, period T23, T25 are flowed at mixed liquor, it does not have such shown in Fig. 4 A variation occurs.Again, when in dilution water is not by normally supply to mensuration container 5, as shown in Figure 4 C, period T2l, T22, T24, T26 are flowed at dilution water, it does not have such shown in Fig. 4 A variation occurs.So, when not there is the such variations in temperature generally occurred, it is possible to determine that be not normally flowed in mensuration container 5 for the liquid such as water sample, dilution water.
Making mixed liquor flow into the period measured in container 5 in order to total nitrogen concentration is measured it addition, mixed liquor flows into period T23, the temperature of the mixed liquor measured in container 5 in total nitrogen concentration measures such as is set to 50 DEG C.Again, mixed liquor flows into period T25 makes mixed liquor flow into the period measured in container 5 in order to total phosphorus concentration is measured, and the temperature of the mixed liquor measured in container 5 in total phosphorus concentration measures such as is set to 50 DEG C.On the other hand, dilution water flows into period T21, T26 and makes the period in dilution water inflow mensuration container 5 in order to mensuration container 5 is carried out.Dilution water flows into period T22, T24 makes dilution water flow into the period measured in container 5 in order to the measured light intensity of dilution water is measured.The temperature measuring the mixed liquor in container 5 can be adjusted to identical temperature in total nitrogen concentration measures and in total phosphorus concentration mensuration as described above, it is also possible to is adjusted to different temperature.
In above embodiment, it is that the situation of reactor 4 or mensuration container 5 is illustrated to inflow part.But, be not limited to such structure, as long as water sample, reagent or dilution water flow into individually or as mixed liquor flow into inflow part, it is also possible to constituted by other container or stream etc..
Water Test Kits is not limited to the structure with two multiported valves 1,2, it is possible to be the structure being provided only with a multiported valve, it is also possible to be provided with the structure of more than 3 multiported valves.Again, as long as at least have the Water Test Kits of the inflow part that water sample, reagent or dilution water flow into individually or flow into as mixed liquor, the kind of valve, pipe arrangement etc. and quantity are all arbitrary, are not limited to structure as above-mentioned embodiment.
