ある。 2. Description of the Related Art Conventionally, the gas atmosphere of a gas corrosion tester is a sulfurous acid gas (SO 2 ), a hydrogen sulfide gas (H 2 S),
Gases that are harmful to the human body, such as nitric oxide (NO) and nitrogen dioxide (NO 2 ), are also used, and their concentrations are harmless when released at higher concentrations than those in the atmosphere. As described above, how to make harmful gas harmless
The current situation was concentrated on the issues of
The most suitable exhaust gas treatment equipment has been developed for various types.
However, technological development of exhaust gas recycling methods is still in progress
Absent. Regarding the above exhaust gas treatment method,

In this case, if the activated carbon or the particulate chemical adsorbent is brought into contact with the activated carbon or the particulate chemical adsorbent while containing the moisture in the exhaust gas, the dew condensation phenomenon occurs, and the activated carbon and the particulate chemical adsorbent become
There is a problem that it does not work because it gets wet.

A dehumidifier using a water cooling method was used. In this method, a metal tube having corrosion resistance to gas, for example, a titanium tube or a PVC tube is used, cooling water is passed through the tube, and the exhaust gas is brought into contact with the tube wall to perform dew condensation and dehumidification. For the water, tap water or industrial water is simply used in a drained state, and when saving water is considered, cooling water is circulated and used by cooling with an air-cooled refrigerator or cooling with a cooling tower. In this case, the device becomes large.

This occurred in the degree control mechanism. That is, humidification is performed by a humidifier of a steam generation system, in which water vapor is sent into a tank by a signal from a humidity controller, and conversely, dehumidification is performed by a method of dew condensation and dehumidification by a cooling pipe provided in a test tank . . In this case, there is a drawback that the gas concentration changes because the gas in the gas atmosphere dissolves into the dew water condensed on the cooling pipe surface during dehumidification.
