Beschreibung
Zusammenfassung:	The invention relates to a wall surface flow guide opposite-impact type venturi integrated mixer. The integrated mixer comprises an outer shell, an EGR core, a cross arm, a fixing pin, a natural gas cross beam and a natural gas impeller, air enters an air channel from an inlet, EGR waste gas sequentially passes through a wall surface round hole in the EGR core and a cross arm central air hole and then enters the air channel to be mixed with the air, the gas flow speed is increased by means of a venturi structure formed in the EGR core, and mixing is promoted by means of the relation between the flow speed and pressure; a wall surface flow guide plate is additionally arranged at a flaring of a venturi structure in the EGR core, so that gas is subjected to primary rotating mixing; and natural gas sequentially passes through a natural gas cross beam wall surface round hole and a natural gas impeller center gas groove and then enters the air channel to be mixed with mixed gas in a secondary rotating mode, the rot
