The utility model provides a solid powder dispersing device for dry desulfurization, which comprises an inlet flue, a rotational flow coupling section and an outlet flue which are sequentially arranged along the flowing direction of raw flue gas, and further comprises a first bypass flue, a bypass fan, a second bypass flue and a dry powder spraying device, the cyclone coupling section is connected with the bypass fan, so that raw flue gas flow entering the cyclone coupling section rotates clockwise or anticlockwise, an inlet of the bypass fan is connected with the inlet flue through a first bypass flue, an outlet of the bypass fan is communicated with the cyclone coupling section through at least one second bypass flue, the second bypass flue is connected with a dry powder spraying device, and the dry powder spraying device is connected with the cyclone coupling section. And the bypass gas flow carrying solid powder is guided into the rotational flow coupling section through the second bypass flue to be mixed
