Heat accumulation type off-gas oxidizing and purifying device

The invention relates to a heat accumulating type waste gas oxygenation-purifying device, of which a shell is internally provided with a catalyst layer and a heat accumulation layer that are distributed up and down. An area where the catalyst layer and the heat accumulation layer are located is evenly divided into a plurality of axial airflow channels. The lower end of each axial airflow channel is provided with a rotary airflow separator, on which a plurality of interphase notches; air inlet balancing chambers are arranged under the rotary airflow separator, and the air inlet balancing chambers are communicated with air inlet nozzles. A plurality of steam purging devices are arranged under the heat accumulation layer, and the steam purging devices comprise a plurality of steam nozzles and effusers that are connected with the nozzles. The device fully utilizes heat generated through reaction to heat the waste gas, thus saving energy; meanwhile, the invention guarantees continuous work through ...
