PROBLEM TO BE SOLVED: To provide a dust collecting apparatus configured to use a single opening/closing valve for two injector pipes so as to usefully utilize the performance (capacity) of the opening/closing valve and cover a large number of filters with the single opening/closing valve.SOLUTION: A diaphragm valve 14 and two adjacent injector valves 11 disposed side by side are coupled to each other by a Y-shaped coupling pipe 18. The Y-shaped coupling pipe 18 includes: a straight pipe part 18a coupled to the diaphragm valve 14; and inclined pipe parts 18b that are symmetrically branched from the straight pipe part 18a and are coupled to an opening end 11w of the injector pipe 11 at an inclination angle &thetas; of 5-15° with respect to an axis A of the injector pipe 11. |
