Abstract
The device for mixing a small quantity of fluid (1) into a the main flow of another fluid (2) in a main channel comprises an injection system (3) and a static mixing unit (4, 5) arranged downstream. The inlet cross section (F) of the mixing unit is divided into sub-areas (F1, F2, F3, F4). The injection system consists of main metering pipes with a plurality of directed metering openings (21). The flow quantities through the metering openings are proportional to the component flows through the corresponding associated sub-areas (F1, F2, F3, F4). This results in uniform thorough mixing over a short distance and with a small pressure drop. The mixing device is particularly suitable for Denox plant.
