Nozzle for bag filter

The invention relates to a nozzle for a bag filter. The nozzle for the bag filter is mounted on a blowing pipe (3) and comprises a nozzle body (2), a nozzle (4) and a flow guiding body (5), wherein the flow guiding body (5) is arranged on the nozzle body (2), a channel with a larger upper end and a smaller lower end is arranged in the flow guiding body (5), and the nozzle (4) is placed in the channel of the flow guiding body and is communicated with the blowing port of the blowing pipe (3). Air-flow is blown into the flow guiding body (5) via the nozzle (4) under guiding, enters from the larger end of the channel in the flow guiding body (5) and flows out from the smaller end of the channel in the flow guiding body (5). Compared with the prior art, the nozzle for the bag filter in the invention has the following advantages: secondary flow guiding effect of the nozzle is utilized, so the air blowing capacity of an ash removal system of the bag filter is greatly improved, and dedusting effect is substantially enhanced.
