The invention relates to the related technical field of ventilation systems, and discloses a marine noise reduction ventilation pipe, a suspension ventilation pipe is separated from a ship body fastener through a magnetic suspension principle, a vibration conduction path is cut off, and meanwhile, adjacent suspension ventilation pipes are separated through magnetic force, so that the adjacent suspension ventilation pipes are not in direct contact, and the noise reduction effect is good. The suspension ventilation pipes are arranged, the path that vibration is conducted along the suspension ventilation pipes is cut off, noise generated by vibration is reduced, in addition, the adjacent suspension ventilation pipes are sealed in a one-way mode through the one-way sealing rings, airflow in the suspension ventilation pipes cannot leak out of the pipes, and meanwhile the arrangement of the conical plates utilizes the Bernoulli principle. Negative pressure is generated on the inner side of the gap between every two adjacent suspension ventilation pipes, external air is sucked into the suspension ventilation pipes through the negative pressure, interaction of air inside and outside the pipes is ingeniously achieved, and the ventilation capacity of the ventilation system is enhanced.
本发明涉及通风系统相关技术领域,公开了一种船用消音通风管,通过磁悬浮的原理将悬浮通风管与船体紧固件分离,断绝了振动的传导途径,同时相邻悬浮通风管之间也通过磁力进行了分隔,使得相邻悬浮通风管之间无直接接触,断绝了振动沿着悬浮通风管传导的途径,以减低振动产生的噪音,另外相邻的悬浮通风管之间还通过单向密封圈进行单向密封,使得悬浮通风管内部气流不会泄露到管道外,同时锥形板的设置利用了伯努利原理,在相邻的悬浮通风管之间缝隙的内侧产生了负压,利用负压将外部的空气吸入悬浮通风管内,巧妙地实现了管内外空气的交互,加强了通风系统的通风能力。
