The utility model discloses an air preheater which comprises a shell, the upper end and the lower end of one side of the shell are provided with a waste gas inlet and a waste gas outlet respectively, the upper end and the lower end of the other side of the shell are provided with an air outlet and an air inlet respectively, a rotatable heat storage element is arranged in the shell, and a flow equalizing assembly is arranged on the waste gas inlet. According to the utility model, the flow equalizing assembly is arranged at the waste gas inlet, so that high-heat waste gas exhausted from the boiler can be shunted, and the waste gas is conveyed into the air pre-heater through the flow equalizing pipes on the flow equalizing assembly, so that the waste gas can be uniformly contacted with the heat storage element after entering the air pre-heater; and the multiple strands of waste gas enter the air pre-heater at the same time, confusion of airflow can be caused, and then the staying time of the waste gas in the air
