Description
Technical field
This utility model is related to natural gas purification field, specifically a kind of natural gas filter.
Background technology
The equipment often using in the transmission ＆ distribution of natural gas filter city gas.Natural gas, because is the reasons such as long-distance sand transport,
(corrosion to pipeline inwall for the natural gas, upper level gas gathering station or gas distribution station are to natural always to carry a small amount of micron-sized impurity
Gas carries out separation, dedusting, the impurity after purification), impact pressure regulator, the normal even running of measuring apparatus, therefore to user
The last leg of supply all must carry out purifying and dedusting to carrying out gas, to ensure tight gas supply.At present, existing filter is natural gas
After being introduced into the filter cylinder purification of filter, then the space between filter cylinder and filter housings is flowed out.Impurity is with the high speed of gas
Inertia motion is done in flowing, and the silk screen being directly impinging in filter cylinder during filter cylinder is directly washed away by air-flow and impurity, use time
Neither long nor can damage, reduce clean-up effect；The filter vat of therefore natural gas filter needs often to clear up or change, and clear every time
Wash to be required for during maintenance disconnecting gas pipeline and just can open filter, otherwise natural gas can leak in a large number, not only wastes, also
Danger close, and pipeline disconnects and can interrupt natural gas regular supply, makes a big impact to producing or living.
Utility model content
The purpose of this utility model is to provide a kind of natural gas filter, with solve in above-mentioned background technology propose ask
Topic.
For achieving the above object, this utility model provides following technical scheme：
A kind of natural gas filter, including：Shell body, cartridge filter, sleeve and gas pipeline, solid in described shell body
Shell internal body portion is to seal against each other two parts of isolation by fixed setting sealing dividing plate, respectively upper plenum and lower cavity；Described
Gas pipeline includes：Main air inlet pipe, branched inlet pipe, main escape pipe and separate trachea；Described cartridge filter include main cartridge filter and
Secondary cartridge filter；Described overhead intracavity setting sleeve and main cartridge filter, sleeve is arranged in main cartridge filter, and main air inlet pipe connects " L "
Shape pipe, " L " shape pipe is located in sleeve and sleeve bottom is pressed close in its end；Described branched inlet pipe respectively with main air inlet pipe and lower cavity
Connection, the secondary cartridge filter of setting in lower cavity, branched inlet pipe is installed the first stop valve, the seam of main air inlet pipe and branched inlet pipe
Second stop valve is installed and " L " shape pipe between, the second stop valve is in normally open, and the first stop valve is in normally off.
As further program of the utility model：Described main escape pipe is connected to upper plenum bottom side, described separates
Trachea is connected to the bottom side of lower cavity and is connected with main escape pipe.
As further program of the utility model：Described overhead top of chamber setting upper press cover, under lower cavity bottom setting
Gland.
As further program of the utility model：Described sleeve is made of stainless steel.
Compared with prior art, the beneficial effects of the utility model are：This utility model utilize sleeve buffering natural gas and
Impurity, in the kinetic energy in exit, reduces the impact to silk screen in cartridge filter for the impurity, effectively prevents cartridge filter from damaging, improves filtration
The service life of device, reduces maintenance or the frequency changed；Using the design of double cartridge filters and branch line, in filter maintenance
When, still can be overhauled without interrupting natural gas supply, be ensured the regular supply of natural gas.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of natural gas filter, including：Shell body 8, cartridge filter, set
Cylinder 10 and gas pipeline, be fixedly installed in described shell body 8 sealing dividing plate 12 by be divided into inside shell body 8 seal against each other every
From two parts, respectively upper plenum 7 and lower cavity 13；Described gas pipeline includes：Main air inlet pipe 4, branched inlet pipe 2, master
Escape pipe 11 and separate trachea 14；Described cartridge filter includes main cartridge filter 61 and secondary cartridge filter 62；Setting set in described upper plenum 7
Cylinder 10 and main cartridge filter 61, sleeve 10 is arranged in main cartridge filter 61, and main air inlet pipe 4 connects " L " shape pipe 9, and " L " shape pipe 9 is located at
Sleeve 10 is interior and sleeve 10 bottom is pressed close in its end, so, flows out natural gas impingement sleeve 10 bottom from " L " shape pipe 9 high speed,
And fill up sleeve 10, finally overflow from the tube port position of sleeve 10, the flow velocity of natural gas will substantially reduce, the impurity portion that it is contained within
Divide and be trapped in sleeve 10, part overflows the impurity of sleeve 10 due to kinetic energy reduction, the impact to silk screen in main cartridge filter 61
Can be obviously reduced, reduce the impaired possibility of main cartridge filter 61；Described branched inlet pipe 2 is connected with main air inlet pipe 4 and lower cavity 13 respectively
Logical, the secondary cartridge filter 62 of setting in lower cavity 13, branched inlet pipe 2 is installed the first stop valve 1, main air inlet pipe 4 and branched inlet pipe 2
Second stop valve 3 is installed between seam and " L " shape pipe 9, the second stop valve 3 is in normally open, and the first stop valve 1 is in often
Closed state, when needing maintenance or more change owner cartridge filter 61, the second stop valve 3 is closed, the first stop valve 1 is opened, natural gas
Then flow in lower cavity 13, flow out after secondary cartridge filter 62 filters, play interim filtration, thus avoiding because of maintenance
Need the drawbacks of die it is ensured that natural gas supply is normally carried out.
Described main escape pipe 11 is connected to upper plenum 7 bottom side, described separates the bottom that trachea 14 is connected to lower cavity 13
Portion side and connecting with main escape pipe 11.
