The invention discloses a blowing tube material return device used for a circulating fluidized bed boiler. The blowing pipe material return device consists of a feeding tube, a discharge tube, the blowing tube material return device, a blowing tube, an air inlet tube and a draught fan, wherein one end of the feeding tube is communicated with the middle part of the blowing tube material return device while the other end is connected with a material return device of the circulating fluidized bed boiler; one end of the discharge tube is communicated with the front end of the blowing tube material return device while the other end is connected into a boiler furnace of the circulating fluidized bed boiler; at least one blowing tube is arranged in the blowing tube material return device; the air inlet of the blowing tube is extended out of the blowing tube material return device and is communicated with the air inlet tube connected with the blowing tube material return device; the other end of the air inlet tube is connected with the draught fan; one end, positioned in the blowing tube material return device, of the blowing tube is closed off by an end cap; and the tube wall positioned in the blowing tube material return device is provided with a plurality of air outlets. The blowing tube material return device serves as a secondary material returning device of the circulating fluidized bed boiler, and solves the problem that ash is emitted from a viewing port and the like of a scraper feeder of the circulating fluidized bed boiler and the problem that a coke is easy to form because the temperature at the bottom of the boiler furnace is over-high, so that the boiler can meet the requirement on production load.
