Semi-submerged marine generator with tail gas noise reduction structure

Abstract

The invention provides a semi-submerged marine generator with a tail gas noise reduction structure. The semi-submerged marine generator with the tail gas noise reduction structure comprises a mounting box and a generator body, wherein a connecting hole is formed in the top of the mounting box; and the bottom of the generator body is fixed to the bottom of the inner wall of the mounting box. The semi-submerged marine generator with the tail gas noise reduction structure has the advantages that flue gas and noise are divided through a dividing pipe, after the flue gas and the noise are divided, on one hand, it is convenient to cool, and the equipment operation safety is improved, and meanwhile, tail gas purification treatment is more thorough, so that damage to purification equipment due to excessive gas output at a time is avoided. The noise of the tail gas is divided, so that after the noise enters a first-stage noise reduction cavity, a sound transmission area is larger, the sound absorption effect and quality in the first-stage noise reduction cavity are improved, and the situation that when the tail gas is directly discharged, the noise absorption range is small, and consequently the use effect of silencing equipment is affected is avoided, and the tail gas noise reduction effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of semi-submersible marine generator sets, in particular to a semi-submersible marine generator with an exhaust noise reduction structure. Background technique [0002] A semi-submersible ship is a special ship design method. Unlike ordinary surface ships, a semi-submersible ship usually has a deeper draft, but it is not completely submerged in the water like a submarine, but part of the hull or structure is exposed. Outside the water surface, due to the high proportion of the volume submerged in the water, the semi-submersible vessel is less likely to be affected by waves on the sea surface, can maintain better stability and is suitable for use as a working platform on the water. [0003] During the operation of the semi-submersible ship, the demand for electricity is relatively large. A dedicated generator set is used to generate electricity to provide sufficient power sources for the semi-submersible ship...
