Background
The special waste fluidized bed incinerator can generate fly ash in the incineration process, and the fly ash is collected by the bag-type dust collector, enters the ash bin and is then conveyed to other storage tanks. As the particle size of the fly ash is small, dust is easy to fly in the transportation process, and a pneumatic conveying system is generally adopted for closed conveying. The fly ash burnt by pneumatically conveying wastes has great abrasion on a conveying pipeline, particularly, the fly ash is easy to have the condition of abrasion leakage at an elbow of the pipeline, and even needs to be stopped and replaced when the fly ash is serious. And dust pollution is caused once the fly ash leaks.
