Abstract
Filter has a filter main body, a container, a first counter room, and a second counter room. A counter air is introduced into the first counter room through the counter air discharge valve, and fine particles trapped in the filter main body are removed and transported to the second counter room. Then, the removed fine particles are further transported to a process portion isolated from an exhaust gas passage, and the fine particles are fired in the process portion. Since the process portion is isolated from the exhaust gas passage, the fine particles in the process portion are not returned to the filter main body. Moreover, since the fine particles are transported by the counter air only to the second counter room, it is possible to reduce an amount of the counter air.
