This invention relates to the field of chemical reaction equipment technology, specifically to a formaldehyde oxidation reactor with an easy-to-clean airflow distribution plate. The reactor includes a reactor body, an inlet chamber, an airflow distribution plate, and a cleaning system. The cleaning system includes a gas collecting hood disposed within the inlet chamber, a gas delivery mechanism that drives the gas collecting hood to rotate around the axis of the reactor body while adhering to the bottom surface of the airflow distribution plate, and a high-pressure pulse source located outside the reactor body.
