Alkali recycling boiler ash blowing equipment with power generation function

The utility model relates to the technical field of boiler ash blowing, in particular to alkali recycling boiler ash blowing equipment with a power generation function. The alkali recycling boiler ash blowing equipment comprises a high-pressure collecting box, a medium-pressure collecting box, an ash blowing tube 2, a main steam pipeline, an auxiliary steam pipeline, a back-pressure steamer power generation device and a steam pressure reduction device. According to the alkali recycling boiler ash blowing equipment with the power generation function, due to adoption of the back-pressure steamer power generation device, depressurized steam can be discharged to blow ash after over-hot steam is adopted to generate power, so that the energy is sufficiently utilized.
