AI Technical Summary

Technical Problem

The noise and vibration generated by diesel generator sets during operation affect the environment and human health. The existing noise reduction technology has limited effect and increases the complexity of the system and maintenance difficulty.

Method used

An exhaust device for a diesel generator set is designed, including front pipes, multiple sets of installed pipes and rear pipes. Through the combination and linkage of inner pulling pipes, medium pulling pipes and outer pulling pipes, multiple expansion chambers are formed to absorb and reduce noise.

Benefits of technology

By increasing the propagation time and interaction times of sound waves, it effectively reduces noise propagation, reduces noise generated by exhaust gas, improves the working environment, and maintains the balance and efficiency of the exhaust system.
