Specific embodiment
For content of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following examples, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1 to Fig. 3, a kind of filtration buffer unit for CNG compressor head porch, including cylinder 1, institute
The one end stating cylinder is provided with air inlet pipe 2, and the outer end of air inlet pipe is provided with air inlet flange disks 3, and cylinder is goed deep in the outlet side of described air inlet pipe
In vivo, and in end it is provided with 45 ° of grooves；Rectify near air inlet in cylinder and air flap 4 is provided with to air inlet pipe position；Entering
The rear side of gas baffle plate is provided with filtration surge bunker 5；Described filtration surge bunker includes fixed plate 6 and the flange end cap being arranged in cylinder
7, described flange end cap passes through bolt 16 adpting flange 8, and described flange is fixedly connected on the end of cylinder 1；In described filtration
It is provided with hollow type filter element 9, described hollow type filter element is fixedly mounted on flange end cap 7 by cartridge support 10 and fixes in surge bunker
On inside support ring 11 between plate 6；The described bottom filtering surge bunker is provided with escape pipe 12, and the end of described escape pipe is provided with out
Gas ring flange 13；Pollution discharge joint 14 is additionally provided with described cylinder.
