Disclosed is a COconcentration reducing device for separating and removing COfrom a gas containing COwith a COadsorbent, the COconcentration reducing device including: an adsorbent container which contains the COadsorbent; and a heating unit which heats the COadsorbent by an induction heating or a dielectric heating. Thus, a ventilation quantity can be reduced when COaccumulated in a room is removed, and an electric power required for the ventilation and the electric power required for air conditioning can be reduced.

COconcentration reducing device

Provided is an exhaust-gas treatment equipment including: a reaction container filled with a gas capture material that captures a particular gas component, the reactor container emitting gas obtained by removing the particular gas component from supplied gas by reaction of the supplied gas with the gas capture material; a temperature measuring element disposed in the reaction container, the temperature measuring element measuring a temperature of the gas capture material in the reaction container; a moving unit that freely moves the temperature measuring element in a direction that is parallel to a flow of the supplied gas flowing in the reaction container; and a control unit that estimates a deterioration state of the gas capture material using temperatures of the gas capture material at a plurality of different positions in the reaction container, the temperatures being measured by the temperature measuring element.

Exhaust-gas treatment equipment and gas-capture-material deterioration-state estimating method

A COseparation unit for recovering COfrom a CO-containing gas by using a solid COcapturing material, in which the amount of used steam is decreased: the unit comprising a capturing material container, a first pipeline for allowing the CO-containing gas to flow therethrough into the capturing material container, a second pipeline for allowing a gas from which COhas been removed to be discharged therethrough, a third pipeline for introducing a steam-containing gas to the inside of the capturing material container, a fourth pipeline for allowing a desorbed CO-containing gas to be discharged therethrough, wherein the unit further includes a compressor for compressing steam, a fifth pipeline for connecting the capturing material container with a suction port of the compressor, and a sixth pipeline for connecting a discharge port of the compressor with the third pipeline.
