Description of the Related Art In a gas processing apparatus of this type, in a first ventilation state (see FIG. 1), the retained heat from a high-temperature treated gas G 'delivered from a combustion chamber 6 is recovered and stored in a second heat storage element 5B. Then, the gas G to be guided to the combustion chamber 6 in the next second ventilation state (see FIG. 2) is preheated by the stored second heat storage element 5B. In the second ventilation state, the retained heat is recovered from the high-temperature treated gas G ′ delivered from the combustion chamber 6 to the first heat storage element 5A, and the stored heat is stored in the first heat storage element 5A.
By A, the gas G to be treated, which is guided to the combustion chamber 6 in the next first ventilation state, is preheated.

There is a problem that the gas to be treated that has been in the passage process or in the vicinity thereof (that is, the remaining untreated gas in the previously ventilated state) is sent to the extraction side of the treated gas as untreated due to the reversal of the ventilation direction. .

嵩む問題があった。However, in this improved apparatus, one heat storage element is stopped and the untreated gas is processed by scavenging, so that the number of heat storage elements is increased, and the apparatus is accordingly increased in size. At the same time, the switching of the ventilation state becomes complicated and the device becomes complicated, which causes a problem that the device cost increases.

問題もあった。In addition, as the size and complexity of the device increase, the surface area of the high-temperature portion increases and the heat loss increases. In addition, as the size and complexity of the device increase, the airflow in the device (particularly the combustion chamber) becomes uneven. Also, there has been a problem that the processing efficiency is lowered due to increased temperature unevenness.
