Anti-blocking automatic circulation ash blowing device for cyclone separator

The invention discloses an anti-blocking automatic circulation ash blowing device for a cyclone separator and aims to solve the defects that materials deposited at the bottom of a cyclone separator need to be cleaned with machine halt, cleaning operation is inconvenient, the working efficiency is low, and serious economic loss can be caused if a system is shut down for a long time to clean off materials. The device comprises a plurality of air ejection tubes, wherein the air ejection tubes are mounted in positions at the lower part of the cyclone separator; one end of each air ejection tube isconnected with a high-pressure gas storage tank; the other end of each air ejection tube is an air ejection end; the air ejection ends are arranged facing downwards and are arranged inside the cyclone separator; and blowing electromagnetic valves are mounted on the air ejection tubes. The anti-blocking automatic circulation ash blowing device for the cyclone separator is capable of blowing air toclean off materials depos
