Beschreibung
Zusammenfassung:	The invention relates to a Wall-surface-flow-guide 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, a natural gas impeller and a natural gas straight joint, wherein the EGR core, the natural gas cross beam and the natural gas impeller are sequentially and fixedly arranged in the outer shell in the direction of a gas channel; air enters the gas channel from an inlet, EGR waste gas sequentially passes through a wall-surface round hole of the EGR core and a central gas hole of the cross arm and then enters the gas channel to be mixed with the air, the flow speed of the gas is increased by means of a Venturi structure formed in the EGR core, and mixing is promoted by means of the relationship between the flow speed and pressure; a wall surface flow guide plate is additionally arranged at a flaring of the Venturi structure in the EGR core, so that the gas is rotationally mixed; and the natural gas sequentially passes thr
