Further, the diesel fuel burner exhaust gas cleaner of the utility model, the DOC encapsulation liner are encapsulated with DPF
Liner is inflated insert.
Further, the diesel fuel burner exhaust gas cleaner of the utility model, the inflated insert is by ceramic fibre system
At.
Further, the diesel fuel burner exhaust gas cleaner of the utility model, the both ends of the DOC carriers and DPF are carried
The both ends of body are enclosed with metal mesh respectively.
According to the above aspect of the present invention, the utility model has at least the following advantages：The diesel fuel burner tail gas of the utility model is net
Makeup is set, and is vented after continuing through DOC (diesel oxidation catalyst) carriers and DPF (diesel particulate filter) carrier, wherein
Atmosphere pollution be largely purified, considerably reduce the pollution to environment.Wherein air inlet ready-packaged joint and
Outlet ready-packaged joint is provided with conducive to quick assembling, by replacing pervious bolt to fasten with essence casting clip, while not by
The limitation of setting angle.The both ends of device use spinning process, can make air-flow after flowing through input bucket, be spread along spinning wall surface,
Play the role of reducing air-flow velocity, improve airflow sectional area, ensures that air-flow can flow through entire carrier current near uniformly
Logical face.After air-flow flows out carrier, output bucket carries out guide functions to air-flow, reduces airflow area, improves air-flow velocity,
Air-flow is set quickly to be smoothly discharged device.The diesel fuel burner exhaust gas cleaner of the utility model is swollen using ceramic fibre
Swelling lining pad carrys out immobilization carrier, and shell is reduced while meeting encapsulation power and is transmitted to the vibration of carrier, while at the both ends of carrier
Surrounding coated metal net, avoids deflation of the high-speed flow to liner.
In conclusion the diesel fuel burner exhaust gas cleaner of the utility model can purification of diesel burner tail gas, subtract
Its few pollutant emission.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
