Device for controlling the swirl of a fluid flowing in a pipeline
The invention relates to a device for controlling the swirl of a fluid ( 2 ) flowing in a pipeline ( 1 ). The invention was based on the object of creating a device with which the adaptation of the swirl ( 2 B) of a fluid ( 2 ) flowing in a pipeline ( 1 ), even in the case of constantly changing initial swirl ( 2 B), to the desired flow conditions in the pipeline ( 1 ) is possible. Said object is achieved in that a swirl measuring device ( 4 ) and a swirl control device ( 6 ) are provided at predetermined positions of the pipeline ( 1 ), and the device has an evaluation and encoder unit ( 5 ), wherein, in the presence of differences between the measured actual swirl ( 2 B) and the desired swirl, a corrective value can be determined by means of the evaluation and encoder unit ( 5 ), and the swirl control device ( 6 ) corresponds with the evaluation and encoder unit ( 5 ) and, by means of the swirl control device ( 6 ), the present swirl ( 2 B) can be adapted to the predetermined desired swirl in accordance with the determined corrective value.
