Provided is a compressed air injection device capable of more assuredly removing dust and powder adhered to a filter of a filter-cloth-type dust collector. The compressed air injection device (5) is provided with an airflow tube (52) and an air amplification device (53). The air amplification device (53) includes an annular part (59) and a tubular ejecting part (60a). The leading end of the ejecting part (60a) extends to the inside of a filter (3), and a cover member (68a) covering an upper end opening part (32) of the filter (3) is arranged on the outer side, of the ejecting part (60a), in the radial direction. The ejecting part (60a) includes a first tube (81) positioned at the upper side thereof and a second tube (82) positioned at the lower side thereof, the first tube (81) and the second tube (82) being connected to each other in such a manner as to be freely separatable from each other. Stoppers (80) are fixed on the outer circumferential surface of the second tube (82), and the second tube (82) is fixed, through fastening of screws, to the first tube (81) at such a position that the lower end surfaces of the stoppers (80) are in contact with the upper surface of the cover member (68a).

The purpose of the present invention is to provide a bag filter air amplification device with an excellent capacity for jetting compressed air from compressed air-jetting holes. The present invention provides a bag filter air amplification device, which is used for back-washing a bag filter. The air amplification device is provided at least with an air-amplifying section and a compressed air-introducing section. The compressed air-introducing section is obtained from: a first member comprising a compressed air-guiding wall; a second member installed contiguously with the air-amplifying section; a fastening section where the first member is joined to the second member; and a shim member, which is sandwiched between the first member and the second member in the fastening section and is for adjusting the width of the compressed air-jetting holes.

Abrégé

The present invention provides a bag filter air amplification device (1), which is an air amplification device that is used for backwashing of bag filters and is equipped at least with: an air-amplifying section (11) provided with an r-shaped inclined surface (111) that spreads towards the outside, an external air intake port (112) that is connected to the r-shaped inclined surface (111) and is for drawing in external air, an amplified air discharging port (113) for discharging the amplified air, and a cylindrical side wall (114) provided from the external air intake port (112) to the amplified air discharging port (113); and a compressed air-introducing section (12) provided with a compressed air-introducing port (121) for introducing compressed air, compressed air-jetting holes (122) for jetting the compressed air towards the air-amplifying section (11), and a curved compressed air-guiding wall (123) for guiding the compressed air introduced from the compressed air-introducing port (121) towards the compressed air-jetting holes (122). The compressed air-jetting holes (122) are provided along the r-shaped inclined surface (111) at the external air intake port (112).
