摘要: The invention discloses a NOx adsorption and removal apparatus employed in the method of passing NOx containing gas into the adsorber 1 filled with NOx adsorbent to adsorb a specific volume of NOx on the adsorbent, passing hot air into the adsorber to desorb NOx, and regenerating the adsorbent, wherein the adsorber is divided in plural zones arranged parallel in the gas flow direction. In this invention, by regenerating after adsorbing NOx in each zone, the regenerating apparatus can be reduced in size, and the energy may be saved by effective utilization of preheat.

摘要: Disclosed is a method of adsorbing and removing NOx, by washing with water a gas discharged by ventilation from highway tunnels in a washing tower as pretreatment, and then adsorbing NOx in the gas with a rotary NOx adsorption unit. The washed gas may be heated by a heater which is placed between the washing tower and the rotary NOx adsorption unit.
