A device for reusing a portable filter bag includes a filter reusing part connected to a connection hose, through which compressed air or steam is introduced, and which is formed to be smaller than the inner diameter of a filter bag. The filter reusing part includes a nozzle box of which upper and lower parts are opened, forming a predetermined internal space, and comprising: a nozzle plate having a plurality of nozzle holes formed of a predetermined size along the outer periphery thereof; an upper cover plate connected to the connection hose through an open hole in the center thereof and closing the upper side of the nozzle plate; and a lower cover plate for closing the lower side of the nozzle plate. The filter reusing part is inserted into the filter bag so as to inject the introduced compressed air or steam to the filter bag through the nozzle holes of the nozzle plate while moving in the vertical direction. |
