First, as shown in Figures 1 and 2, substantially the first pipe section 10, foreign matter incorporating section 30, second pipe portion 20, first baffle plate B11 and second baffle B21 can be comprised according to the ventilated gas purifying device 100 of section Example of the present invention.
Here, described first pipe section 10 is the devices Exhaust Gas G1 comprising powder or the ash (ash) of solids form or the fuel material of unburned state or incombustible non-combustible matter or the foreign matter 1 such as nitrogen bond, carbon bond burning and produce afterwards being guided to first direction (below of Fig. 1), illustrated first pipe section 10 can be formed as corner tubular, or the various shape such as cylindrical shape, tubulose.
Further, described foreign matter incorporating section 30 is formed in below described first pipe section 10, is directed to described first direction and the foreign matter 1 comprised in the described Exhaust Gas G1 fallen for receiving.
Here, as shown in Figure 1, described foreign matter incorporating section 30 can be the funnel (hopper) of the flaw shape gone recessed down, to make described foreign matter 1 pile up in below.
In addition, the Purge gas outlet H that described second pipe portion 20 is formed with the side in described first pipe section 10 is communicated with, by segregating foreign objects 1 and the Purge gas G2 be cleaned guides to second direction (rear of Fig. 1).Illustrated second pipe portion 20 can be formed as corner tubular or the various shape such as cylindrical shape, tubulose.
Here, second direction can be to by first pipe section 10 flow into Exhaust Gas be finally disposed to outside before be used for process Exhaust Gas harmful components treating apparatus flow into direction.At this moment, described treating apparatus can be SCR equipment, and the Exhaust Gas flowed into described second direction can be directed to the Catalytic Layer forming SCR equipment.
Here, as shown in Figures 1 and 2, the lead-in curve portion 40 with the 6th radius of curvature R 6 can be formed between described first pipe section 10 and described foreign matter incorporating section 30.
As shown in Figure 1, described first baffle plate B11 can be projecting to the inside of described first pipe section 10, so that the Exhaust Gas G1 of described first pipe section 10 is through backward described second pipe portion 20, described foreign matter 1 incorporating section 30 conversion direction, and in order to promote that the direction of Exhaust Gas G1 is changed, the first baffle plate B11 can form at least more than one circular surface S.
Such as, as shown in Figure 1, the structure of described first baffle plate B11 can be that structure above described Purge gas outlet H is fixed in tiltedly outstanding, the rear end that dips down to direction, described foreign matter 1 incorporating section 30, its front end.
