Anti-ash-blocking wide-channel waveform heat storage element

The utility model discloses an anti-ash-blocking wide-channel wave-shaped heat storage element which comprises a front end plate, a rear end plate is arranged on one side of the front end plate, the front end plate and the rear end plate are connected through rib plates, a plurality of heat storage elements are evenly arranged between the rib plates, and the heat storage elements and the rib plates are connected through fixing assemblies. Mounting grooves matched with the rib plates are symmetrically formed in the two sides of the front end plate and the two sides of the rear end plate correspondingly, and a plurality of containing grooves matched with the heat storage elements are evenly formed in the bottoms of the rib plates. The cleanability of the heat storage element can be improved under the matching action of the smooth grooves, the fishbone-shaped grooves and the corrugated grooves, and the problems of acid dew point corrosion and ammonium bisulfate ash blocking of the air pre-heater can be effective
