The invention discloses a low-noise diesel power generation unit for ships. The low-noise diesel power generation unit comprises a box body and a diesel power generation unit, and is characterized in that the box body is provided with an air inlet and an air outlet, the air inlet is arranged on the top surface and the bottom surface of the box body on one side of a power generator, the air outlet is arranged on the top surface and the bottom surface of the box body on one side of a diesel engine, and an air inlet silencing area, a unit layout area, a smoke exhaust pipeline silencing area and an air exhaust silencing area are arranged in the box body; the unit layout area is arranged on the central position of the bottom of the inner side of the box body, the smoke exhaust pipeline silencing area is arranged above the unit layout area, and a smoke exhaust pipeline is connected with a silencing device; the air inlet silencing area is arranged on a power generator end of the diesel power generation unit, and an air inlet silencing plate is arranged in the air inlet silencing area; the air exhaust silencing area is arranged on the diesel engine end of the diesel power generation unit, and an air exhaust silencing baffle plate is arranged in the air exhaust silencing area. The purpose for lowering the noise is realized by comprehensively adopting the technologies such as sound insulation, sound absorption and the like, the structure is simple, and the noise lowering effect is obvious.
Description
technical field [0001] The invention relates to a diesel generator set, in particular to a low-noise diesel generator set for ships. Background technique [0002] Diesel generator set is a kind of power equipment that uses diesel engine as the prime mover and drives synchronous generator to generate electricity. Diesel generator set is a power generation device with quick start, convenient operation and maintenance, low investment and strong adaptability to the environment. [0003] Diesel generator sets have the disadvantages of large vibration and high noise during operation. The noise mainly comes from the engine, including explosion noise, fan noise, exhaust noise, etc. If necessary noise reduction measures are not taken, the noise of the unit operation will affect the surrounding environment. cause serious damage. Contents of the invention [0004] The object of the present invention is to provide a low-noise diesel generator set for ships with good noise-reduction ...
