Description
Technical field
The utility model relates to a kind of casing gas collecting apparatus for air filter, belong to air filter technology
Field.
Background technology
Air filter is the source device of air separation plant, is that the air before air compressor is played filtration, purification effect
's.The cycle of operation of general air separation plant was at about 20～30 years, and its operation energy consumption about more than 80% derives from air compressor
Energy consumption, therefore the energy consumption of compressor will directly influence the economy that equipment runs.
Air filter is due to operating pressure low (negative pressure is run, and has certain vacuum), and the control of its flow velocity height will
Directly affect the height of air compressor machine energy consumption.
In existing two-layer air filter layout, because the existence of gathering tube just necessarily increases threeway and elbow, with
Time add energy consumption, the crushing equivalent length of a threeway is much larger than the pipe fitting such as valve, elbow, reduced pipe, and along with caliber
Increase and increase.Therefore in the design of filter outlet pipe, the setting of pipe fitting should be reduced as far as possible, especially threeway, the most suitably
Increase the arm sectional area that confluxes, to reduce local pressure fall.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and a kind of simple in construction is provided, safety can
Lean on, energy-saving and cost-reducing, can effectively reduce the energy consumption in air separation unit longtime running, improve air separation unit performance driving economy for sky
The casing gas collecting apparatus of air filter.
The purpose of this utility model completes by following technical solution: a kind of case for two-layer air filter
Body gas collecting apparatus, it include a configuration be arranged on two-layer air filter after casing air duct, described casing air lead to
Road is made up of, at casing air duct one piece of U-shaped header board, two pieces of U-shaped back plate, perforate circle neck and adpting flange and two blocks of side plates
Intermediate formation have one " Y shape " air duct, one end of this air duct has on the air that corresponding filter two-layer exports respectively
Layer import and the import of air lower floor, the other end has by the air outlet slit of straight tube before adpting flange connection compressor.
As preferably: described casing air duct is previously by house steward and the arm connection two-layer air filtration of confluxing of confluxing
Device, and described in conflux 1.3-1.5 times that arm sectional area sum is house steward's sectional area before house steward, air is through house steward of confluxing
After confluxing, point upper and lower two-layer enters described casing gas collecting apparatus；Described U-shaped header board uses streamlined water conservancy diversion to arrange, by two blocks of streams
Line style steel plate splicing forms.
Main Function of the present utility model is to reduce energy loss before air enters compressor as far as possible, reduces energy
Consumption, will not cause any harmful effect during air filter and air compressor normally use to equipment.
This utility model has simple in construction, safe and reliable, energy-saving and cost-reducing, can effectively reduce in air separation unit longtime running
Energy consumption, improve the features such as air separation unit performance driving economy.
Accompanying drawing explanation
Fig. 1 is the attachment structure schematic diagram of casing gas collecting apparatus described in the utility model.
Fig. 2 is the structural representation of casing gas collecting apparatus described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is detailed introduction: Fig. 1, shown in 2, one described in the utility model
For the casing gas collecting apparatus of two-layer air filter, it include a configuration be arranged on two-layer air filter after casing air
Passage, described casing air duct is by one piece of U-shaped header board 1, two pieces of U-shaped back plate 2, perforate circle neck 4 and adpting flange 5 and two
Block side plate 3 is constituted, and the intermediate formation at casing air duct has one " Y shape " air duct, and one end of this air duct has respectively
The air upper strata import 6 of corresponding filter two-layer outlet and air lower floor import 7, the other end has by adpting flange 5 connection pressure
The air outlet slit 9 of straight tube 8 before contracting machine；The air entered from air filter 10 can pass through in passage gently, enters air pressure
Straight tube before contracting machine.
Described casing air duct is previously by house steward and the arm connection two-layer air filter that confluxes of confluxing, and described remittance
Before stream house steward 1.3-1.5 times that arm sectional area sum is house steward's sectional area, air is to divide after the confluxing of house steward of confluxing
Lower two-layer enters described casing gas collecting apparatus；Described U-shaped header board uses streamlined water conservancy diversion to arrange, two blocks of streamlined steel plates spell
Connect and form.
Embodiment: described casing gas collecting apparatus side comprises the import of air upper strata and the import of air lower floor, opposite side is empty
Gas exports, and mesophase is connected to " Y shape " air duct；Described air duct mainly by one piece of U-shaped header board, two pieces of U-shaped back plate, is opened
Hole circle neck and adpting flange, and two pieces of side plates compositions.The arm that confluxes described in air warp after filter filtration enters and always confluxes
Pipe, 1.3-1.5 times that arm sectional area sum is house steward's sectional area before house steward of confluxing, compensate for described in conflux arm elbow
And arm accesses the crushing at house steward's threeway；Air point upper and lower two-layer entrance described casing gas collection dress after house steward of confluxing is confluxed again
Putting, the air duct in gas collecting apparatus is set to " Y shape ", reduces impact resistance and the kinetic energy loss of air-flow, reaches energy-saving and cost-reducing
Purpose；U-shaped header board uses streamlined diversion Design, maximizes and reduces gas-flow resistance and play guide functions to flowing through air.
The branch diameter that confluxes before described casing gas collecting apparatus calculates and carries out according to the following formula:
Wherein:
D confluxes and props up a bore (unit: mm)；
D confluxes total bore (unit: mm)；
N-confluxes arm quantity
Described casing gas collecting apparatus side is connected to air filter two-layer by welding manner and exports, and opposite side is by flange
It is connected to straight tube before compressor.Described casing gas collecting apparatus is mainly by one piece of U-shaped header board, two pieces of U-shaped back plate, perforate circle neck and company
Acting flange, and two pieces of side plates compositions；
The arm that confluxes described in the utility model determines according to the house steward's pipe diameter size that confluxes, to conflux described in can offsetting
Crushing at pipe bend and at arm access house steward's threeway is as the criterion；Described casing gas collecting apparatus import is according to air filter two-layer
Outlet size determines, the outlet of described casing gas collecting apparatus then determines according to straight tube caliber before compressor；Whole casing holds when running
By lower negative pressure.Package unit has simple in construction, safe and reliable, energy-saving and cost-reducing, can effectively reduce in air separation unit longtime running
Energy consumption, be effectively improved the feature of air separation unit performance driving economy.
