The invention relates to a horizontal dense-phase circulating fluidizing dry-
tower flue-gas desulfurization device belonging to the field of
environmental engineering. The horizontal dense-phase circulating fluidizing dry-
tower flue-gas desulfurization device comprises a circulating fluidizing chamber (1), a dense-phase chamber (2), a Roots blower (3), a feeding
pipe (4), a
flue gas inlet (5), a booster fan (6) and a bag-type
dust collector (7) and is characterized in that a stirring shaft (8), a gas
pipe (9) and a gas distribution
pipe (10) are arranged, wherein the stirring shaft (8) is mounted in the dense-phase chamber and provides more collision chances for a desulfurizer and the
flue gas in the dense-phase chamber so as to improve the desulfurization efficiency; the gas pipe (9) is connected with the Roots blower for providing the circulating fluidizing chamber and the dense-phase chamber with fluidized
wind power; and the gas distribution pipe (10) is mounted at the
tail ends of the gas pipe (9) and the feeding pipe (4), and the
wind power of the Roots blower is blown to all directions through the gas distribution pipe (10). The invention solves the problems of higher
energy consumption, easy foot pedal blockage, great occupied area, and the like existing in the traditional dense-phase circulating fluidizing dry-
tower desulfurization device and improves the desulfurization efficiency.
