Description

Technical Field

[0001] The invention relates to the technical field of air preheater dust cleaning, in particular to a vibration device for air preheater dust cleaning equipment. Background Art

[0002] With the environmental protection requirements for ultra-low flue gas emissions, while the ammonia method is being used to remove the nitrate, ammonia reacts with SO3 to form ammonium bisulfate. The boiler air preheater wall temperature operates in the ammonium bisulfate condensation area formed. The liquid ammonium bisulfate component adheres to the surface of the air preheater tube, accumulating and obstructing the flow of flue gas. The viscous ammonium bisulfate adheres to the surface of the air preheater tube, making it difficult for the cleaning equipment to clean the accumulated ash.

[0003] The dust on the surface of the horizontal air preheater is mostly a mixture of semi-fluid or hardened components with a certain viscosity. When the comb plate moves horizontally between the heat exchange tubes to clean the dust, the mixture will adhere to the comb plate, resulting in dust accumulation on the tube plates at both ends of the air preheater, and the stroke range of the comb plate is gradually compressed. Therefore, the present invention provides a vibration device for the dust cleaning equipment. Summary of the invention
