<p>Blast furnace gas dry dust collection equipment (1) comprising a dry dust collector (4), an inlet-side pipe (24), an outlet-side pipe (25), a branch pipe (7), a heat exchanger (9), and a mixer (10). The branch pipe (7) is branched from the outlet-side pipe (25) and diverts some of blast furnace gas flowing through the outlet-side pipe (25). The heat exchanger (9) heats or cools the blast furnace gas that flows through a temperature adjustment path (13A). A mixer (10) mixes the blast furnace gas that has been heated or cooled by the heat exchanger (9) with the blast furnace gas flowing through the inlet-side pipe (24), such that the blast furnace gas on the inlet side of the dry dust collector (4) is within a prescribed temperature range.</p> |
