Coal injection gun with flow guide structure

The coal injection gun with the flow guide structure comprises an air inlet pipe, a pulverized coal inlet pipe, a pulverized coal spray pipe and a three-way piece, a flow guide pipe is arranged between the pulverized coal spray pipe and the three-way piece, the pulverized coal inlet pipe, the pulverized coal spray pipe and the flow guide pipe are located on the same straight line, and a plurality of flow guide ribs are arranged on the top of the flow guide pipe side by side. The flow guide ribs are arranged in the axial direction of the pulverized coal spray pipe, and flow guide grooves are formed between the flow guide ribs. The flow guide pipe is arranged between the three-way piece of the coal injection gun and the pulverized coal injection gun, and the flow guide rib is arranged at the top of the flow guide pipe in a penetrating manner, so that by adopting the structure, pulverized coal airflow reflected to the top of the flow guide pipe from the bottom of the three-way piece can be well guided, turbulent
