Description

Technical Field

[0001] The invention relates to a flexibly adjustable diesel generator. Background Art

[0002] Generator set operation is a kind of backup power supply, which is widely used in places such as troops, hospitals, schools, and construction sites. Existing diesel generators generally use diesel engines to drive generators to generate electricity, and the diesel engine and generator are installed inside the generator box to achieve overall assembly; with the rapid development of the economy and the continuous increase of electric energy, diesel generators are more and more widely used. Since the diesel engine needs to discharge exhaust gas to the outside, in order to protect the environment, a filter element is generally installed on the exhaust pipe of the diesel engine for filtering. However, the filter element needs to be replaced after a period of filtration. If the filter element is not replaced in time, it will not only be blocked, but also lose the filtering effect, so that the atmosphere is polluted. However, in the existing working environment, the replacement of the filter element generally requires shutdown and replacement, which is time-consuming and inefficient. In particular, the filter element cannot be replaced in real time when the diesel generator is working, which makes the existing diesel generator inflexible in the structure of filter element replacement.
