Patent ID: 11828300

Abstract:
Disclosed is a corrosion-resistant air preheater capable of slowing down dust deposit. The air preheater comprises a shell, an air inlet is fixedly formed in the side wall of the shell, an air outlet is fixedly formed in the side, away from the air inlet, of the shell, a flue gas through pipe is fixedly arranged on the inner side wall of the shell, rotating assemblies are arranged on the outer side wall of the flue gas through pipe, a flue gas inlet box is fixedly arranged at the top of the shell. According to the corrosion-resistant air preheater, an air pressure plate is pushed through the flue gas pressure intensity, and then the air pressure plate can descend. After the air pressure plate descends, rotating blades can rotate under the flowing effect of flue gas, then a movable rod rotates, and a scraping plate is further enabled to rotate.
