Description

TECHNICAL FIELD

The dust collecting device pushes the dust at the second opening of the hopper through the setting of the pushing mechanism and the dredging rod, so that the dust in the hopper continuously falls into the dust collecting box, and the dust in the hopper avoids blocking the second opening.

[0004] In order to solve the problem that the dust in the ash bucket is easy to stick together when the humidity of the dust entering the ash bucket is large. For example, in some flue gas dust removal systems after wet desulfurization, if the water in the flue gas is not fully separated, the dust entering the ash bucket will absorb water and form a block. Especially in high humidity environment or in rainy weather, this situation may be more serious, and some dust itself has high viscosity, such as fly ash generated by burning some high volatile coal, which contains a lot of unburned carbon and sticky components. These sticky dust is easy to accumulate and stick together in the ash bucket, and gradually block the ash bucket over time, which needs to be improved. UTILITY MODEL CONTENTS
