US 12,601,664 B2 · Low-concentration air pollutant selective detection device

Abstract

The present invention relates to a low-concentration air pollutant selective detection device and, more specifically, to a low-concentration air pollutant selective detection device capable of detecting a low-concentration air pollutant with high sensitivity, and selectively detecting an air pollutant when necessary. The low-concentration air pollutant selective detection device of the present invention comprises: a sensor which is located in a flow path, through which the gas moves, to detect contaminants in the gas; and a concentrator part which, by including an adsorbent that is positioned in the flow path of the gas that moves to the sensor and adsorbs contaminants in the gas, and a desorption means that is positioned adjacent to the adsorbent to individually desorb different contaminants from the adsorbent, delivers the concentrated contaminants to the sensor.

Dependent claims

A low-concentration air pollutant selective detection device, comprising:

a sensor located in a flow path, through which gas moves, to detect contaminants in the gas;
and
at least one concentrator part that delivers the contaminants, which are concentrated, to the sensor, the at least one concentrator part including:
a plurality of adsorbents positioned in the flow path to adsorb the contaminants in the gas, and
a desorption means positioned adjacent to each of the plurality of adsorbents for desorbing the contaminants from each of the adsorbents,
wherein
at least two of the plurality of adsorbents are formed of different materials to adsorb different contaminants, and
the desorption means desorbs the different contaminants from the at least two adsorbents individually.
