Abstract
The utility model discloses a gas filter. The gas filter comprises a housing, a filtering core barrel, an upper cover and a drain outlet part; the upper part of the filtering core barrel is inclined in 45 degrees. The gas filter is characterized in that an air inlet and an air outlet are respectively formed in two sides of the housing; the drain outlet part is mounted at the bottom part of the housing; the filtering core barrel communicated with the air outlet is mounted in the housing; a screening mesh is mounted between the air inlet and the housing; the housing is connected with the upper cover through a lifting bolt; a back-flushing port is mounted in the upper cover. The gas filter has the advantages that the dust containing capacity of the filter is improved, the resistance is reduced, the operation is convenient, the filtering area of the filter is remained, and the washing cycle and the service life of a filter core barrel are prolonged.
Description
Technical field
The utility model relates to a kind of gas filter, belongs to gas technology field.
Background technology
In the transmission & distribution of city gas, often use natural gas filter, the natural gas, because that enters gas distribution station is carried or other reasons for remote, always with the even running of equipment in a small amount of micron order or submicron order impurity effect natural gas.Existing filter is the filter core that natural gas first directly enters filter, after filter core purifies, again from the space outflow filter between filter core and filter housings, because impurity does inertia motion with the flow at high speed of gas, natural gas can directly impact on filter core, this place's silk screen is owing to directly receiving washing away of air-flow and impurity, be damaged at first, cause filter area to reduce, gas does turbulent motion in filter core, make the small dust sink-float can not sedimentation in filter core, reduced filter effect and the life cycle of filter, increased maintenance workload.
Method content
For addressing the above problem, the utility model provides a kind of gas filter, comprise housing, cross filter core bucket, upper cover and sewage draining exit parts, described 45 ° of the filter core bucket upper angled of crossing, described housing both sides are provided with air inlet and gas outlet, described housing bottom is installed sewage draining exit parts, described enclosure interior was installed filter core bucket, and the described filter core bucket of crossing is communicated with gas outlet, between described air inlet and housing, installs and screens out net, described housing is connected by lifting bolt with upper cover, and described upper cover is installed back blow port.
Preferably, the described filter core bucket of crossing adopts Cr
18ni
9ti stainless steel wire is worked out.
Preferably, described sewage draining exit parts comprise blowoff valve and blow-off line.
Filter process: make the natural gas that contains impurity enter the air inlet of described filter housings, because described air inlet is with filter core bucket distance is larger excessively, form a toroidal cavity, natural gas is different because of proportion from impurity, can be in described toroidal cavity Gravity Separation, after through the described impurity that screens out net and can remove larger particles, these particles all come off at described housing bottom, can be through described blow-off line, be discharged into outside described blowoff valve, the gas flow that screens out net filtration described in passing through will carry out this filtration by crossing filter core bucket equably again.The back blow port that described case top lid is installed, can carry out blowback to crossing filter core bucket, reduces maintenance workload.
Advantage of the present utility model is: make dust containing capacity in filter increase, reduce resistance, easy to operate, keep the filter area of filter, can extend the service life of cleaning frequency and described cartridge bucket.

Detailed description of the invention
As shown in Figure 1, a kind of gas filter, comprise housing (1), cross filter core bucket (2), upper cover (3) and sewage draining exit parts (4), described 45 ° of filter core bucket (2) upper angled of crossing, described housing (1) both sides are provided with air inlet (5) and gas outlet (6), sewage draining exit parts (4) are installed in described housing (1) bottom, filter core bucket (2) was installed in described housing (1) inside, the described filter core bucket (2) of crossing is communicated with gas outlet (6), between described air inlet (5) and housing (1), install and screen out net (7), described housing (1) is connected by lifting bolt (8) with upper cover (3), described upper cover (3) is installed back blow port (9).The described filter core bucket (2) of crossing adopts Cr
18ni
9ti stainless steel wire is worked out.Described sewage draining exit parts (4) comprise blowoff valve (11) and blow-off line (10).
Filter process: make the natural gas that contains impurity enter the air inlet (5) of described filter housings, because described air inlet (5) is with filter core bucket (2) distance is larger excessively, form a toroidal cavity, natural gas is different because of proportion from impurity, can be in described toroidal cavity Gravity Separation, after through the described impurity that screens out net (7) and can remove larger particles, these particles all come off in described housing (1) bottom, can be through described blow-off line (10), be discharged into outside described blowoff valve (11), the gas flow that screens out net (7) filtration described in process will pass through equably filter core bucket (2) and carry out this filtration again.The back blow port (9) that described housing (1) upper cover is installed, can carry out blowback to crossing filter core bucket (2), reduces maintenance workload.
Above embodiment is only for illustrating this method; and the not restriction to this method; the those of ordinary skill in relevant technologies field; in the case of not departing from the spirit and scope of this method; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to the category of this method, and the scope of patent protection of this method should be defined by the claims.
Claims (3)
1. a gas filter, comprise housing (1), cross filter core bucket (2), upper cover (3) and sewage draining exit parts (4), described 45 ° of filter core bucket (2) upper angled of crossing, described housing (1) both sides are provided with air inlet (5) and gas outlet (6), sewage draining exit parts (4) are installed in described housing (1) bottom, filter core bucket (2) was installed in described housing (1) inside, the described filter core bucket (2) of crossing is communicated with gas outlet (6), between described air inlet (5) and housing (1), install and screen out net (7), described housing (1) is connected by lifting bolt (8) with upper cover (3), described upper cover (3) is installed back blow port (9).
