RECYCLING PLANT OF ASPHALT WASTE MATERIAL, ASPHALT PLANT, AND RECYCLING METHOD OF ASPHALT WASTE MATERIAL
To provide a recycling plant of asphalt waste material capable of preventing a heat storage combustion type deodorizer unit from being forcibly stopped due to the rise in temperature in a combustion chamber, an asphalt plant, and a recycling method of asphalt waste material.SOLUTION: A recycling plant 1 includes: a drying furnace for recycled aggregate 4 for drying recycled aggregate 2 obtained by crushing asphalt waste material; and a deodorizer unit 7 for deodorizing the exhaust gas of the drying furnace for recycled aggregate 4. The deodorizer unit 7 includes: a combustion chamber that has a deodorizing burner 72; and two or more heat accumulation chambers each communicating with the combustion chamber. The deodorizer unit is a thermal accumulating combustion type deodorizer unit 7 in which exhaust gas of the drying furnace for recycled aggregate 4 is supplied to one of the heat accumulation chambers to preheat, the odorous components are oxidatively decomposed by heating the preheated exhaust gas with a deodorizing burner 72 in the combustion chamber, and the exhaust gas whose odor components are oxidatively decomposed is exhausted after heat recovery in another heat accumulation chamber. The thermal accumulating combustion type deodorizer unit 7 has an outside air introduction part for introducing outside air into the heat accumulation chamber.SELECTED DRAWING: Figure 1
【課題】燃焼室内の温度の上昇によって蓄熱燃焼式脱臭装置が強制的に停止されるのを抑制することができるアスファルト廃材のリサイクルプラント、アスファルトプラント及びアスファルト廃材のリサイクル方法を提供する。【解決手段】リサイクルプラント１は、アスファルト廃材を破砕した再生骨材２を乾燥するための再生骨材用乾燥炉４と、再生骨材用乾燥炉４の排ガスを脱臭する脱臭装置７と、を備えており、脱臭装置７は、脱臭用バーナ７２を有する燃焼室と、燃焼室にそれぞれ連通する２つ以上の蓄熱室と、を備え、再生骨材用乾燥炉４の排ガスを一の前記蓄熱室に供給して予熱し、予熱された排ガスを燃焼室で脱臭用バーナ７２により加熱して臭気成分を酸化分解し、臭気成分が酸化分解された排ガスを他の蓄熱室で熱回収してから排出する蓄熱燃焼式脱臭装置７であり、蓄熱燃焼式脱臭装置７は、蓄熱室に外気を導入するための外気導入部を備えている。【選択図】図１
