Description

Technical Field

[0001] The invention relates to the technical field of diesel generator set silencing, in particular to an environmentally friendly silencing diesel generator set. Background Art

[0002] Diesel generator sets generate huge noise when running. Soundproof boxes are commonly used hardware measures when supporting generator sets. Their purpose is to reduce noise. In terms of the use environment, in addition to being used in indoor environments such as machine rooms and distribution rooms, they will also be used in noise-sensitive environments such as buildings to replace the main power supply system as an emergency power supply. Existing diesel generator sets need to replace three filters, one oil and one liquid during maintenance. The three filters refer to the oil filter element, methanol filter element and air filter element, one oil refers to the engine oil, and one liquid refers to the antifreeze. At the same time, the daily fuel tank is an accessory of the generator set, and the inside of the tank also needs to be cleaned and maintained in time. In addition to maintenance, the operating surface of the machine should be simple, comfortable and easy to operate during normal inspection.

[0003] At present, the main noise reduction method for silent diesel generator sets is to stick sound-absorbing cotton inside the box, the air inlet is an air inlet louver, and the exhaust is also directly discharged from the silent box through the air outlet louver. The maintenance door of the silent box has upper and lower door frames, and the equipped base oil tank is welded on the base frame; the current shortcomings of methanol silent boxes: 1. The air inlet and outlet are of louver structure with large openings. When the machine is running, a large part of the wind noise and the noise generated by the machine will be transmitted from the box. Although it can achieve a certain noise reduction effect, the noise control effect is not very good; 2. The inspection door of the silent box has upper and lower door frames. Under the same box body dimensions, when the unit is under maintenance, the opening size of the inspection door is small, which will be affected to a certain extent during the maintenance process; in view of this, the present application proposes an environmentally friendly silent diesel generator set.
