Apparatus for collecting powder in exhaust gas with an increased collection capacity and exhaust gas treatment equipment provided with same

An exhaust gas treatment equipment comprising:

• an adsorption reaction device for treating exhaust gas using an adsorption reaction;
• and
• a device for collecting powder in exhaust gas that collects powder contained in exhaust gas before the exhaust gas flows into an adsorption reaction device;
• wherein the device for collecting powder in exhaust gas includes a filter body, which includes a filter member that filters and feeds the exhaust gas to the adsorption reaction device, and which is disposed below the adsorption reaction device, and includes a housing which provides a filter installation space internally for storing the powder separated from the filter member,
• which housing is a space projected below the adsorption reaction device, and which includes a filter installation unit which internally provides a filter installation space where the filter is installed, and an expansion unit which is formed so as to protrude sideways from the filter installation unit and provides an expansion space which communicates internally with the filter installation space, and
• the internal space is expanded by the expansion space so as to increase the powder collection capacity, and
• a suction port for sucking in the exhaust gas is installed in the expansion unit.
