Embodiment 2

[0035] Embodiment 2 is a kind of oil production generator, and its exhaust port is connected with silencing exhaust hose 1 .

[0036] Working process and principle of the present invention:

[0037] The exhaust pipe is set so that the hose 1 can be bent according to the needs during installation, and it can also reduce vibration. Installing the silencer device in the hose 1 greatly reduces the cost. After the airflow enters the hose 1, most of it will directly enter the silencer The pipe 3, through the second sound-absorbing board 5 arranged in layers, finally passes through the first sound-absorbing board 11 to decompose the airflow into countless weak and fine airflows, and another part of the airflow will enter the asbestos 2, and will pass through the asbestos 2 through the secondary silencing The through hole 10 enters the muffler pipe 3 and can also be decomposed into countless strands to achieve the purpose of silencing. The auxiliary muffler through hole 10 of the muff...

Abstract

The invention relates to the technical field of silencing, in particular to a silencing exhaust hose. The silencing exhaust hose comprises a hose body provided with a hollow cavity, wherein an air inlet and an air outlet are formed in two ends of the hose body; a silencer is arranged in the hose body; the length of the silencer is smaller than that of the hose body. According to the silencing exhaust hose, airflow is decomposed to countless weak and fine airflow through layers of silencing plates, so that the purpose of silencing is achieved; a part of airflow can be weakened through auxiliary silencing through holes of a silencing tube, meanwhile, the airflow is prevented from being blocked between the silencing plates, so that the purpose of silencing is achieved. The silencing exhaust hose has the advantages of simple structure, low cost and good silencing effect.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a noise reduction exhaust hose and a diesel generator thereof. Background technique [0002] The position of the internal combustion engine in modern production and life cannot be replaced. For example, diesel generators are widely used in the production and operation of industrial and mining enterprises because of their good economical and power performance. Noise seriously affects people's normal production and life. Larger noises can cause harm to people's hearing. Therefore, how to reduce or eliminate noise has always been the focus of people's attention. The existing diesel generators have a very large external hose. The silencer device, resulting in high cost, and increased the size of the diesel generator. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem of complex structure and high...
