Device and method for disposing dust bin blockage of blast-furnace gas bag-type dust remover

The invention provides a device and method for disposing dust bin blockage of a blast-furnace gas bag-type dust remover and belongs to the technical field of blast-furnace gas dust removal devices and methods. The device is used for disposing dust bin blockage of the blast-furnace gas bag-type dust remover. According to the technical scheme, holes are formed in the bin walls of the lower-portion gas dust storage positions of an upper dust bin and a middle bin respectively, the hole-formed positions are connected with an upper dust bin nitrogen gas stirring pipe and a middle bin nitrogen gas stirring pipe respectively, and the upper dust bin nitrogen gas stirring pipe and the middle bin nitrogen gas stirring pipe are connected with a main nitrogen gas pipe through pipes. When blockage of the middle bin or the upper dust bin is found, the upper dust bin nitrogen gas stirring pipe and the middle bin nitrogen gas stirring pipe are opened, gas dust adhered to the dust bin is impacted and stirred by utilizing nitrogen gas, and the gas dust with larger viscosity is smoothly discharged out. The device has the advantages of being simple in structure, low in cost and convenient to operate, and the method can ensure smooth dust discharge of the blast-furnace gas bag-type dust remover, keep normal operation of the blast-furnace gas bag-type dust remover and avoid the influence on production of dust remover failures.
