The utility model relates to an ash-conveying device in a post-mixing header of an SCR denitration system. An ash-gathering device is arranged in the post-ammonia-air mixing header of the device. The bottom of the header moves in the axial direction to gather the dust deposited at the bottom. The gathered dust is pushed to the ash discharge hole by the circular push plate, and enters the L-shaped ash conveying pipe of the jet ash conveying device from the ash discharge hole. The air pipe sends the high-pressure air into the L-shaped ash conveying pipe, and the discharged dust is blown into the flue by the high-pressure air; After mixing, the dust at the bottom of the header is raised and enters the flue with the ammonia-air mixed gas; the utility model solves the problem that the bottom of the header after the ammonia-air mixing is easy to deposit dust, and avoids blocking the whole after-ammonia-air mixing header in serious cases. problem, to ensure the stable operation of the header after ammonia-air mixing. |
