The invention discloses a reverse blowing regeneration rotational flow filter. The reverse blowing regeneration rotational flow filter is mainly formed by a shell, a three-way electromagnetic valve, a T-shaped air inlet, a secondary filter electromagnetic valve, a secondary static filter, a ceramic wall flow filter, an upstream pressure sensor, a temperature sensor, a downstream pressure sensor, an air storage tank, an air source, an air storage tank one-way valve, an electromagnetic valve and a vehicle-mounted ECU, and is characterized in that under the control of the vehicle-mounted ECU, when reverse blowing regeneration needs to be conducted on the reverse blowing regeneration rotational flow filter through the three-way electromagnetic valve, the secondary filter electromagnetic valve, the air storage tank one-way valve, the electromagnetic valve and the like, a uniform rotational flow pressure field is formed in a filter downstream cavity, regenerated airflow is reversely blown to ...
