Title:
排ガスの処理装置及び処理方法
Document Type and Number:
Japanese Patent JP4868617
Kind Code:
B2
Abstract:
An exhaust gas treating apparatus includes an adsorption tower (20) that has an adsorption layer filled with an adsorbent and a heat transfer path through which heat is transferred to the adsorption layer. The apparatus performs switching among the following processes: an adsorption process of introducing an exhaust gas from an engine (10) into the adsorption layer of the adsorption tower so that target components to be treated, including NO X , in the exhaust gas are adsorbed by the adsorbent; a desorption process of introducing the exhaust gas into the heat transfer path of the adsorption tower to heat the adsorption layer and introducing a desorption gas into the heated adsorption layer so that the target components are desorbed from the adsorbent, and a cooling process of introducing a cooling gas into the adsorption layer of the adsorption tower to cool the adsorption layer and introducing the cooling gas that has passed through the adsorption layer into an inlet of the engine. Thus, the apparatus can treat the exhaust gas with a small amount of energy consumption and without performing a wet treatment.
