Title:
FLY ASH CONVEYING SYSTEM OF WASTE INCINERATOR
Document Type and Number:
WIPO Patent Application WO/2020/118591
Kind Code:
A1
Abstract:
A fly ash conveying system of a waste incinerator, which from top to bottom successively comprises according to a fly ash conveying direction: an ash collecting hopper (1), a front ash pipe (5.1), a rear ash pipe (5.2), a working ash drop pipe (5.3), a submerged chain conveyor (7) and a submerged slag pool. Fly ash falls into the ash collecting hopper (1), the front ash pipe (5.1), the rear ash pipe (5.2), and the working ash drop pipe (5.3) successively from top to bottom, then enters the submerged chain conveyor (7), and is finally conveyed to the submerged slag pool. A J-shaped valve (10) is disposed at a corner at which the front ash pipe (5.1) and the rear ash pipe (5.2) are connected. A normally open ash pipe valve (8.2) is disposed at a corner at which the rear ash pipe (5.2) and the working ash drop pipe (5.3) are connected. A first air distribution pipe (9.1) is disposed in the J-shaped valve (10), and a second air distribution pipe (9.2) is disposed at a front end of the normally open ash pipe valve (8.2). The first air distribution pipe (9.1) and the second air distribution pipe (9.2) are each provided thereon with several small air outlet holes. Compressed air conveying pipes (12.1, 12.2) connected to the air distribution pipes (9.1, 9.2) are further disposed; and when fly ash accumulates at the corners, compressed air is separately conveyed to the first air distribution pipe (9.1) and the second air distribution pipe (9.2) by means of the compressed air conveying pipes (12.1, 12.2), and is sprayed out from each of the small air outlet holes to blow away the accumulated fly ash, so that the fly ash falls into the ash pipes, thereby achieving the function of ash removal.
