Abstract

The present invention is directed to a method for treating an exhaust gas containing dust composed of a glassy material and a sticky material consisting principally of CaO in a gas parallel flow type solid-gas contact reactor, the aforesaid method being characterized by including the step of forcing the dust to collide with a solid surface on the upstream side of the reactor in order to separate the dust into the glassy material and the sticky material consisting principally of CaO; and the present invention is also directed to an apparatus for the above method, the apparatus being characterized by including a collision device for colliding with the dust which is disposed in an exhaust gas flow path on an upstream side of the reactor.
