Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to an tail gas processor for an air-cooled diesel engine. Background Art

[0002] With the rapid development of industrialization, air-cooled diesel engines are widely used in various mechanical equipment as an important power source. However, air-cooled diesel engines will produce a large amount of exhaust gas during operation, including harmful substances such as carbon monoxide, nitrogen oxides, hydrocarbons and particulate matter, which pose a serious threat to the environment and human health. At present, the exhaust gas treatment method for air-cooled diesel engines is mostly to purify the exhaust gas by installing an exhaust gas processor, but the exhaust gas emission process will generate a lot of noise, and usually a muffler needs to be installed, resulting in the exhaust gas processor and the muffler being two separate devices, which need to be installed and set up separately, which brings more troubles to use. Therefore, it is necessary to design an exhaust gas processor for air-cooled diesel engines. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. By providing a silencer component, it can be wrapped around the outside of the processor housing through a sound insulation cover. The concave and convex grooves on the sound insulation cover can effectively reflect the generated noise and block the outward propagation of the noise. At the same time, by inserting the noise reduction plate into the limit frame, it can play a dual noise reduction role, and can conveniently combine the exhaust gas treatment and noise reduction functions into one. At the same time, the gap between the noise reduction plate, the sound insulation cover and the processor housing can be used to store air.
