Suction type slag removal device of heat storage heating furnace and slag removal method achieved through suction type slag removal device

A suction type slag removal device of a heat storage heating furnace comprises a slag rotating system, and the slag rotating system is used for crushing and rotating oxide scales in the furnace and sucking the oxide scales into a conveying pipe; the slag separation system is connected with the conveying pipe and is used for completely separating the oxide scale and the dust conveyed by the conveying pipe from the gas; the smoke discharging system is connected with the slag separating system and is used for discharging clean gas generated by the slag separating system; and the compressed air system is connected with the conveying pipe and serves as a material crushing driving air source. The invention also discloses a slag removal method realized by using the device. The heat storage heating furnace suction type slag removal method has the advantages of being small in investment, safe, reliable, energy-saving, environment-friendly, high in operation efficiency and the like, the labor cost and the furnace shutd
