Abstract:
A deodorizing system for removing odor components generated from thermal equipment using a gas current as a heat source, comprising:thermal equipment;a deodorizing furnace provided with a burner and a pair of circulating openings; andan out-of-furnace circulating path, which includes a circulating passage connected with the thermal equipment, and a circulating fan, the circulating path being connected to the deodorizing furnace through the pair of circulating openings; the out-of-furnace circulating path taking out combustion exhaust gas from the deodorizing furnace to the outside of the furnace through one of the circulating openings and flowing back the combustion exhaust gas into the deodorizing furnace through the other circulating opening after passing the combustion exhaust gas through the thermal equipment; and the out-of-furnace circulating path having regenerators provided at positions adjacent the pair of circulating openings of the deodorizing furnace, the circulating fan and a passage switching apparatus periodically switching and inverting a direction of a gas current between the circulating fan and the regenerators,wherein changing over the passage switching apparatus causes a direction of the gas current to the deodorizing furnace to be periodically inverted; combustion exhaust gas taken out from the deodorizing furnace being heated to a temperature required in the thermal equipment through the regenerators and then supplied to the thermal equipment; and recirculating gas containing odor components generated in the thermal equipment being heated in the regenerators and then flowing back into the deodorizing furnace for combustion.
