METHOD FOR ATTENUATING NOISE PRODUCED BY PIPES AND PIPE ARRANGEMENT

摘要

The present invention relates to a method for attenuating noise produced by steam flowing through a pipe, comprising the steps of providing a pipe arrangement (10), which comprises an inner pipe (12) that defines in its inside an inner flow channel (14) which progresses in pipe direction (16) of the inner pipe (12), and an outer pipe (18) that surrounds the inner pipe (12) and progresses substantially parallel thereto, thereby defining an outer flow channel (20) between the two pipes (12, 18) which is substantially parallel to the inner flow channel (14), establishing a steam flow (22) in and along the inner flow channel (14), and establishing a water flow (28) in and along the outer flow channel (20), said water flow (28) being adapted to attenuate a noise produced by said steam flow (22) flowing through the inner flow channel (14).

1. A method for attenuating noise produced by pipes transporting a flow of fluids, gases, particles or combinations of any of those, comprising the steps of:
providing a pipe arrangement, which comprises an inner pipe that defines in its inside an inner flow channel, which progresses in pipe direction of the inner pipe, and an outer pipe that surrounds the inner pipe and progresses substantially parallel thereto, thereby defining an outer flow channel between the two pipes which is substantially parallel to the inner flow channel, establishing a steam flow in and along the inner flow channel, and establishing a water flow in and along the outer flow channel, said water flow being adapted to attenuate a noise produced by said steam flow ;2 flowing through the inner flow channel, andstreaming gas into the water flow to generate a stream of gas bubbles within said water flow.
