Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a low-energy consumption dust cleaning device for bag dust collectors. Background Art

[0002] The bag dust collector is a commonly used industrial dust collector. It has been widely used due to its simple structure and low cost. The ordinary bag dust collector mainly includes a filter chamber, the upper end of which is sealed by a porous plate. A filter bag extends downward from each through hole of the porous plate. The lower end of the filter bag is closed, and the upper end is connected to the upper chamber above the filter chamber; the lower end of the filter chamber is connected to the ash hopper; the lower part of the filter chamber has an air inlet connected to the filter chamber, and the upper chamber has an air outlet; after the dust-laden gas enters the filter chamber from the air inlet, it can only pass through the filter bag and then enter the upper chamber, and The dust is discharged from the air outlet. During this process, the dust is filtered on the outer surface of the filter bag. As the dust removal operation proceeds, the dust on the surface of the filter bag accumulates more and more, which will cause the filtration efficiency to drop rapidly. Therefore, the current bag dust collector is also equipped with a blowing system in the upper chamber. During the dust removal operation, the air filtering is stopped at regular intervals, and the blowing system is started to blow the inside of the filter bag to make the dust attached to the surface of the bag fall outward. It can be seen that this type of bag dust collector cannot perform dust removal operations continuously, and the dust removal efficiency is greatly limited. In addition, the cost of the blowing system is relatively high.

[0003] The application (patent) number is: CN201510666475.9. A high-efficiency bag dust collector includes a filter chamber, the upper end of which is closed by a porous plate and the lower end is connected to an ash hopper; an air inlet is provided at the lower part of the filter chamber; an upper chamber is provided above the filter chamber, and an air outlet is provided on the side of the upper chamber; a filter bag extends downward from each through hole of the porous plate; the air in the filter chamber can only enter the upper chamber after passing through the filter bag; the air inlet is connected to a sub-cavity at the lower part of the filter chamber, and the sub-cavity is connected upward parallel to The filter bag is provided with an exhaust pipe, and at least one exhaust pipe is arranged next to each filter bag; the port of the exhaust pipe extends to near the porous plate; the surface of the exhaust pipe is provided with side holes facing the filter bag along the axial direction. The dust collector can realize continuous dust removal operation and keep less dust on the surface of the filter bag at all times, has high dust removal efficiency and low cost. However, the cleaning point of the outer peripheral surface of the filter bag of the bag dust collector is fixed, which makes the cleaning surface of the outer peripheral surface of the filter bag smaller, reduces the filtering area of ​​the filter bag, and thus the dust removal efficiency needs to be improved. Summary of the Invention
