Specific implementation mode
Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is further described in detail.The present invention not by with
Lower embodiment limitation.
Referring to Fig. 1, a kind of packaged type described in this patent and granule capturing device is easily regenerated, including metal box 1, exhaust
Pipe fitting 2, unitary tubes fixed frame 3, c-type pipe 4, strainer 5, the pressure sensor 6 with indicator light, natural gas cylinder 7, gas
Body valve 8, fuel gas pipeline 9, catch 10 and igniter 11.
The benefit of the present invention is to connect the exhaust outlet of special vehicle and the granule capturing device of the present invention, traps vehicle
A large amount of soots for generating when work are regenerated after trapping saturation.It is various sizes of that this device can change flanged joint
Exhaust outlet is suitable for various types of special vehicles, can effectively trap and remove the soot generated when work.Knot of the present invention
Structure is compact, and applicability is good.1) metal box 1 is used for fixing c-type pipe 4 and fuel gas pipeline 9, simultaneously using unitary tubes fixed frame 3
C-type pipe 4 and fuel gas pipeline 9 are fixed on the internal face of metal box 1, universal wheel is installed below in metal box 1, with this come reach can
Mobile requirement.2) exhaust fitting 2 and the connection of the exhaust outlet of special vehicle are connected using cone-shaped flange, can be connected in this way
The exhaust outlet of various sizes of special vehicle, this outward flange successive fashion good airproof performance and energy high temperature resistant.3) c-type pipe 4 is for drawing
Guide gas, and the flow velocity of exhaust can be reduced, to reduce noise, reduce the trapping that exhaust flow rate is equally convenient for particle.C-type
The pipe diameter size of pipe 4 is 120~195mm.4) strainer 5 is used for trap particulate matter, and the upper hole of strainer is square hole, and mesh density is
100~200CSI (hole count is per square inch), thickness are 1~3mm, and number is fixed according to the capacity of vehicle.In addition, in order to more preferable
Ground traps soot, and the density of 5 mesh of strainer is with the linear incremental arrangement of discharge directions.5) pressure sensor of indicator light is carried

It can light and send out early warning, granule capturing device needs to regenerate at this time.6) fuel gas pipeline 9 is for ensureing that granule capturing device needs again
It is filled with natural gas in entire c-type pipe 4 when raw, just can ensure that the carbon soot particles on strainer are completely removed in this way.7) catch is anti-
Only particulate matter blocks the junction of fuel gas pipeline and c-type pipe.
After the pipeline that the exhaust of special vehicle passes through granule capturing device, particulate matter can be captured on strainer.In addition, working as
When exhaust is by c-type pipe, catch can block the junction of fuel gas pipeline and c-type pipe, this ensure that fuel gas pipeline will not be blocked
Plug.When back pressure at granule capturing device air exit reaches 18~35kPa of limit value, the pressure sensor meeting of indicator light is carried
Bright light early warning needs to regenerate at this time.When granule capturing device regenerates, c-type pipe air inlet is sealed, then connects natural gas gas
Bottle opens gas valve 8, and natural gas can blow afloat catch 10, and such natural gas can be full of entire C successively along discharge directions
Type pipe, then igniter fire combustion of natural gas and are captured in the particulate matter on strainer and can also be burned off, closed after 6~10min
Natural gas and valve are closed, is blown at the air inlet of c-type pipe, the residual gas in pipeline is blown out, arrives this granule capturing device
Regenerative process terminate, can be continuing with.Trapping of carbon soot particles and removal efficiency are up to 95% or more during this.
The above is only a preferred embodiment of the present invention, it can not assert that the specific implementation of the present invention is confined to this
A little explanations, it is noted that for those skilled in the art, without departing from the inventive concept of the premise,
Several improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
