Abstract:
1. An injector element for the reduction or removal of pollutants from streams containing waste gases and improving the operation thereof by injecting gas mixtures, gas-liquid mixtures or gas solid mixtures comprising: a. a hollow, outer tube with a longitudinal axis and two ends, one of said ends being an inlet end and the other being an outlet end; b. an axially controllable smaller inner tube with an inlet end and an outlet end inserted longitudinally within said outer tube so that inlet end and said outlet end match with said inlet end and said outlet end of said outer tube; c. a connecting rod connected to said inlet end of said smaller tube to control said axial position of said smaller tube along the longitudinal axis of said hollow, outer tube; d. a trumpet-shaped exit formed about the outlet end of said smaller hollow tube, said trumpet-shaped exit fitting snugly within said hollow, outer tube, and which serves to form a valve regulating the flow within an annulus formed between said outer and said inner tubes and wherein said trumpet-shaped exit forms an angle of between 45 and 135 degrees from a line along said longitudinal axis; so that when a pollution containing waste stream in a closed venting container is permitted to flow past and perpendicular to said outlet end of said outer tube and a pollution reacting stream is caused to flow into said inlet end and to exit from said outlet end, said trumpet-shaped exit creates both and outer and inner flow pattern within said closed venting container enhancing the mixing of said pollution reacting stream with said pollution containing stream so as to improve contact, thereby enhancing the removal of said pollutants from said pollution containing stream.
