Provided is an airflow disturbance type carbon fiber spreading device. The device includes an unwinding module, an unwinding tension control module, an airflow disturbance spreading module, a winding tension stabilizing module, a deviation correction module and a winding module which are sequentially arranged along a feeding direction. The spreading mechanism includes an airflow disturbance spreading module, the airflow disturbance spreading module includes two airflow disturbance spreading assemblies, each airflow disturbance spreading assembly includes a centrifugal fan, the centrifugal fan communicates with the bottom of an airflow duct, and three spreading guide shafts are arranged side by side on the top of the airflow duct. A tension adjusting assembly is provided between the airflow disturbance spreading assemblies. A seventh spreading guide shaft (13) is located at the upper port of an airflow duct I (25) and is connected to a slider module II (34).
