Low-temperature economizer anti-abrasion structure based on active interference in whole flowing process in flue

The invention discloses a low-temperature economizer anti-abrasion structure based on active interference in the whole flow process in a flue, which comprises a flow guide arc plate group arranged at a downstream elbow of an air pre-heater and close to an inner corner; the T-shaped forked shunting arc plate group is arranged at the downstream of the flow guide arc plate group; the T-shaped forked middle chamfer flue wall plate group is arranged at the T-shaped forked part in the middle; the low-temperature economizer inlet upstream elbow flow guide arc plate group is arranged at the downstream of the T-shaped forked flow dividing arc plate group; and the local anti-abrasion flow equalizing plate is arranged at the upstream of the inlet of the low-temperature economizer and the downstream of the elbow flow guide arc plate group. The problem of uniform airflow distribution in the height direction is solved through the low-temperature economizer inlet upstream one-way flared flue, the problem of uniform airflow
