The ozone sensor 7 includes, for example, three electrodes (a working electrode, a reference electrode, and a counter electrode) that are in contact with an electrolyte phase and a gas phase.
And is driven by the ozone concentration measuring device 8. The ozone sensor 7 causes a reaction of O 3 + 2e − → O 2 + O 2− due to ozone (O 3 ) approaching its working electrode, and O 2 + 2H at the counter electrode adsorbing oxygen in the air. By generating a reaction of + → H 2 O equivalent to that of the working electrode, the reaction of O 3 + 2e − + 2H + → O 2 + H 2 O is generated as a whole. The ozone concentration measuring device 8 detects the current flowing through the reference electrode along with the O 3 oxidation reaction in the ozone sensor 7 as described above, so that the ozone in the building 1 in which the ozone sensor 7 is provided ( The O 3 ) concentration is detected.

When the ozone concentration in the building 1 detected at 1 exceeds the first monitoring value, an alarm is issued and a signal to stop the operation of the ozone generator 2 is issued, and further the blower 6 is operated. And the ozone gas treatment device 5
Is issuing a signal to start. Then, the alarm prompts the worker in the building 1 to quickly move out, and the operation of the ozone generator 2 is stopped to prevent further generation (leakage) of ozone. At the same time, by operating the ozone gas treatment device 5, ozone contained in the air in the building 1 is decomposed and the air is purified to reduce the ozone concentration in the building 1.

A signal for prohibiting the operation of the exhaust fan 4 is issued. Then, by blocking the communication between the inside of the building 1 and the outside (atmosphere) via the exhaust duct 3, it is possible to prevent leakage of ozone leaking into the building 1 into the atmosphere. still,
Although not particularly shown, the ozone gas treatment device 5 may be changed to the first monitoring value described above and operated when the second monitoring value is exceeded.

It goes without saying that the disassembling process is continuously executed. Then, when the ozone concentration in the building 1 decreases due to the ozone decomposition processing by the ozone gas processing device 5, and the above-mentioned first monitoring value falls below, for example, the above-mentioned alarm is released, and the exhaust duct 3 is shut off. Is released.

Further, when the ozone generator 2 generates a very small amount of ozone due to its operation as in the arc welding device described above, the operation of the ozone gas treatment device 5 is performed when the ozone concentration becomes high as described above. It is preferable to operate the ozone gas treatment device 5 in synchronism with the operation of the arc welding device, instead of automatically activating. Then, when the ozone concentration becomes high, the ozone gas treatment device 5 may be continuously operated regardless of the stop of the operation of the arc welding device (ozone generator 2).

効果が奏せられる。According to the ozone gas monitoring device thus constructed, the ozone concentration in the building 1 in which the ozone generator 2 is installed is monitored, and an alarm is issued when the ozone concentration exceeds the first monitored value. Since the ozone generator 2 is stopped and the operation of the ozone generator 2 is stopped, it is possible to effectively suppress an increase in the ozone concentration in the building 1 by using the ozone gas treatment device 5 provided in the building 1. Further, in spite of such measures, when the ozone concentration in the building 1 exceeds the second monitoring value, the air discharge itself from the building 1 is shut off, so that the ozone in the atmosphere is blocked. It is possible to obtain a great practical effect, such as effective prevention of air pollution and prevention of air pollution.
