Patent ID: 7665884

Claim:
A mixing system, comprising: a flow passage; a plurality of mixing elements disposed in grid formation next to one another in a common mounting plane as seen in a direction of flow in said flow passage, said mixing elements each having a respective center axis and a plurality of mixing vanes disposed around said center axis, adjacent said mixing vanes of respective said mixing elements in a projection plane onto a normal plane to said center axis, in each case having an overlap; and at least one injection nozzle for injecting a reaction medium being disposed upstream of at least some of said mixing elements in said flow passage, said injection nozzle having an exit and in each case being dimensioned such that the reaction medium at said exit, has an exit velocity being higher by an excess factor than a flow medium in said flow passage, and said mixing elements dimensioned such that a quotient formed from a degree of overlap of said adjacent mixing vanes (in percent) and the excess factor is from 0.1 to 5.
