For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0026] The utility model discloses a dust catcher internal air inlet structure.
[0027] Referring to Figure 2 And Figure 3 A dust collector internal air inlet structure, including support beam 1, support beam 1 is welded on the lateral wall of dust collector.

In the embodiment, one ash hopper 7 corresponds to one air inlet hopper 2, so that the length of air inlet elbow pipe 5 is reduced, and after flue gas enters air inlet hopper 2, it first passes through air inlet inclined pipe 3 and air inlet pipe 4, and then enters air inlet elbow pipe 5, utilizes the centripetal force generated by the trajectory arc of air inlet elbow pipe 5, makes flue gas flush under the flue, thereby reducing the ash deposition.
