AI Technical Summary
Existing boiler ash removal devices cannot completely settle ash and slag during spray dust suppression, and the ash and slag easily adhere to the inner wall of the device.
A dust suppression device for boiler ash discharge was designed. It uses a combination of annular pipe and vertical pipe spray holes in the tank body with rotating cross blades to spray water. Combined with a crushing component, the ash is sprayed and crushed. The rotating cross blades fully contact the water and throw off the ash, avoiding adhesion. The inclined structure design prevents ash from sticking.
This achieves full agglomeration and settling of ash and slag, avoiding ash and slag splashing and adhesion, and improving the dust suppression effect and stability of the device.
