供給のための零ガス用電磁弁１９が接続しである。As the above-mentioned hydrogen/oxygen concentration measuring device, JP-A-5940248 [Hydrogen/oxygen concentration measuring device” has been proposed. FIG. 3 is a diagram showing its overall configuration. The circulation pipes 2, 2 that communicate with the inside of the reactor containment vessel 1 are for drawing out the atmosphere inside the reactor containment vessel 1 to the outside and drawing it back in for reflux. An on-off valve 3 is located in the middle of the circulation pipes 2, 2.
, 3, a sample electromagnetic valve 4, a non-dispersive infrared gas analyzer 5 in the moisture measuring section, a dehumidifier 6, a pump 7.7, a pressure regulating valve 8°8, and a hydrogen meter 10, an oxygen meter 11, and a corrector. 1
A measuring section 9 consisting of 2 and a flow meter 13 are inserted. Regarding the non-dispersive infrared gas analyzer 5, before measuring the gas concentration in the measuring section 9, the amount of moisture in the atmosphere is measured, and this signal is sent to the corrector 1 in the measuring section 9.
2 to correct the measured values of hydrogen and oxygen. FIG. 4 is a block diagram of the moisture detection section, in which the non-dispersive infrared gas analyzer 5 has a sample cell 14 equipped with an interference filter 15.
The sample cell 14 is composed of an infrared light source 16 and a concave mirror 1γ in the upper part, and a thermal lightning pair 18 and a concave mirror 17 in the lower part.
As shown in the figure, interference filters 15 are installed at right angles to the flow path of the atmospheric gas above and below the center of the disc-shaped part to block light of wavelengths other than the water absorption band, and interfere with parallel light from an infrared light source 16. The atmospheric gas is transmitted through the filter 15, received by the thermocouple 18, and the moisture in the atmospheric gas is measured based on the electromotive force according to the intensity and change of the received infrared rays. After moisture is removed from the atmospheric gas that has passed through the moisture measuring section in a dehumidifier 6, the hydrogen and oxygen concentrations are measured in a hydrogen meter 10 and an oxygen meter 11 in the measuring section 9, respectively, and then the non-dispersive infrared gas analyzer Based on the moisture signal from the dehumidifier 5, the corrector 12 accurately detects the concentration of hydrogen and oxygen in the atmosphere before dehumidification by the dehumidifier 6. Note that a zero gas solenoid valve 19 for supplying calibration waste is connected between the sample solenoid valve 4 and the non-dispersive infrared gas analyzer 5.

I am busy with the process and carry out the operations according to the procedure, but the calibration usually takes 1
00% water vapor and N2 gas. But 10
Calibration work using 0% water vapor and N2 gas cannot be easily performed due to the need to check for water vapor condensation, and if the calibration period is prolonged, the characteristics of the infrared scum analyzer 5 tend to drift, resulting in a decrease in the accuracy of moisture correction. I rarely had the problem of doing so.

A calibration plate 21 exhibiting a certain degree of infrared absorption is arranged in a freely insertable manner. The calibration plate 21 is made of a material having characteristics such as absorption of infrared rays of about 100% of water vapor. Conventional non-dispersive infrared gas analyzer that uses water vapor each time 5
Since the calibration takes time and the work is complicated, calibration is performed periodically using water vapor from the steam generator 42, and calibration using the calibration plate 21 is normally performed.

の指示が安定する程度の時間流し続ける。Next, the effect of the above configuration will be explained. An automatic calibration and measurement work system is built in the sequencer 46 in advance. During regular inspections, the non-dispersive infrared gas analyzer 20 is calibrated using 100% water vapor from the moisture electromagnetic valve 41 and the water vapor generator 42. Normal measurement work begins with a start signal from the sequencer 46, which activates the zero gas solenoid valve 19.
is opened, the span gas solenoid valve 40 and the sample solenoid valve 4 are closed, zero gas is introduced into the non-dispersive infrared gas analyzer 20 and the measuring section 30, and the measurement instructions of the hydrogen meter 31 and oxygen meter 32 are stabilized. Continue to flow zero gas for a period of time. Note that, for example, N2 gas is used as the zero gas. Next, the sequencer 46 includes the corrector 33 of the measurement unit 30, the zero point/span point calibration calculators 43, 44, 45 of the hydrogen meter 31 and the oxygen meter 32.
, and the respective zero point/span point calibration calculators 43, 44 . ．． 115 for automatic adjustment. At this time, the calibration plate 21 of the non-dispersive infrared gas analyzer 20 shown in FIG. 2 is not interposed between the sample cell 14 and the thermocouple 18. Next, after inserting the calibration plate 21 between the sample cell 14 and the thermocouple 18, the zero gas solenoid valve 19 is closed.
The span gas solenoid valve 40 is opened, and the span gas is allowed to flow through the hydrogen meter 31 and oxygen meter 32, and continues to flow for a period of time until the indications on the hydrogen meter 31 and oxygen meter 32 are stabilized.

0 moisture corrector 33, the calibration calculator 43 of the hydrogen meter 31 and oxygen meter 32, and the zero point/span point calibration calculator 44 and 45. 31 and the oxygen meter 32 are calibrated to match each display value of the span gas.

This measurement work is also carried out automatically and frequently by the sequencer 46 following the above-mentioned calibration work, so that high accuracy can always be maintained and direct operation by an operator is not required.

効果が得られることは勿論である。Although the above embodiment describes a case where a non-dispersive infrared gas analyzer is used in the moisture measuring section, other types of moisture measuring instruments may also be used, and the type and supply method of the zero gas and span gas may be changed. It goes without saying that the same effect as in the above embodiment can be obtained even if the moisture supply means for moisture correction is a means other than the steam generator.

とを特徴とする水素・酸素濃度自動測定装置。In a hydrogen/oxygen concentration measurement device that performs moisture correction for hydrogen and oxygen gases containing moisture, a water vapor generator, a solenoid valve for zero gas, and a solenoid valve for span gas are installed upstream of the moisture detector in the circulation piping via a solenoid valve for moisture. A calibration plate is inserted into and removed from the moisture detector, and a moisture compensator that corrects the hydrogen meter and oxygen meter based on the signal from the moisture detector, and the zero point and span point of the hydrogen meter and oxygen meter. 1. An automatic hydrogen/oxygen concentration measuring device, characterized in that it is provided with a sequencer that sequentially controls calibration and measurement operations of the moisture detector, hydrogen meter, oxygen meter, etc. according to a set order.
