The specific embodiment
As shown in Figure 2, the centrifugal guide vane 3 that uses at present comprises body 5 and a plurality of blades 6 that body 5 outer surfaces are provided with, and has the through hole 7 of interspersed centrifugal conduit 2 on the said body 5.
Like Fig. 3, shown in 4, the present invention is with the lower surface 12 of said through hole 7 outstanding centrifugal guide vanes 3 and extends certain distance that form straight tube body 8 below 12 in said centrifugal guide vane 3 lower surfaces, said straight tube body 8 is vertical with the lower surface 12 of centrifugal guide vane 3.
Above the certain distance of said extension, as long as this distance can guarantee and help air-flow centrifugal motion eddy flow cylindrical shell 1 in, generally be with prior art in centrifugal conduit 2 to be deep into the length of eddy flow cylindrical shell 1 inside the same.
