Description
Technical field
The invention belongs to gas filtration technical field, particularly relate to a kind of filtration dress being built in equipment gaseous phase outlet
Put.
Background technology
Molecular sieve, activated carbon are adsorbents conventional in oil, chemical plant installations.In use because of its material itself
Characteristic there is gradually efflorescence, peel off the situation of dust granules.When process gas is by equipment such as molecular sieve tower, active carbon filters
These dust granules are taken out of by Shi Keneng, along with air-flow enters in downstream process equipment, long term accumulation may to valve operation, under
Trip process equipment has undesirable effect, and serious may destroy process runs well, buries accident potential.Solve this at present
The Normal practice of problem is a particulate filter of connecting in this kind equipment rear end.Equipped with the filter of special substance in particulate filter
Core, usually filters the granule foreign of micron level.Particulate filter typically requires configuration teletransmission differential manometer, when pressure reduction reaches
Need during certain value to change filter element, meet technological requirement with the flow and pressure ensureing gas after filtering.Because filtering accuracy is high, use
It is substantially reduced its service life in filtering the unstripped gas containing big dust particle.For avoiding replacing filter element to cause device to stop transport, work
Particulate filter important in factory sets up the using and the reserved.But owing in unstripped gas, granule content does not reduce the replacement frequency of filter element
Do not reduce, and add the operation of two complete equipment switchings.
Summary of the invention
Object of the present invention is to provide a kind of defecator being built in equipment gaseous phase outlet；It is built in activated carbon mistake
The similar devices outlet at bottom coarse filter device such as filter or molecular sieve tower, it carries out coarse filtration to the gas carrying dust granules, incites somebody to action
The dust collection filtered down, at the mouth of pipe, is removed when overhaul of the equipments.
The object of the present invention is achieved like this:
A kind of defecator being built in equipment gaseous phase outlet, arranges filter element in the outlet(discharge) flange of outlet；Cross
Filtering element is connected with companion flange, and companion flange external diameter is consistent with the external diameter of rear end connection pipeline and wall thickness with wall thickness；Cross filtering element
Part is made up of skeleton and silk screen；Skeleton is open at one end, the cylinder of one end closing, cylinder barrel is provided with perforate, on barrel
Cover silk screen；The uncovered aperture connecting pipeline more than rear end of skeleton；Companion flange is relative with the flange face of outlet(discharge) flange, middle
It is provided with pad, seals with bolt, nut screwing clamping.
The nominal diameter of described outlet connects pipeline than rear end and is preferably greater than or equal to three grades.
The skeleton of described preferred filter element is steel plate.
Open pore size on described preferred skeleton isThe perforate gross area is 3～5 that air inlet section is long-pending
Times.
Described preferred silk screen packing material is 20～60 mesh.Preferably silk screen is metal.
The preferably length of skeleton cylinder takes 1.5～2 times of drum diameter
Product manufacturing of the present invention processing is simple, easy for installation, opens and inspect easily.Latter aspect is used to alleviate rear end filter
Burden, reduces rear end filter element replacing frequency；What on the other hand saving operation investment, increase process unit ran stablizes
Property.
Accompanying drawing explanation
A kind of coarse filter being built in equipment outlet conduit of Fig. 1；
Fig. 2 element enlarged drawing；
Wherein: 1. outlet, 2. outlet(discharge) flange, 3. companion flange, 4. filter element, 5. skeleton, 6. silk screen, 7. connecting tube
Road, 8. pad, 9. bolt, 10. nut.
Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2: filter element 4 is set in the outlet(discharge) flange 2 of outlet 1；Filter element and companion flange 3
Connecting, companion flange 3 external diameter is consistent with the external diameter of rear end connection pipeline 7 and wall thickness with wall thickness；Filter element is by skeleton 5 and silk screen
6 are constituted；Skeleton 5 is open at one end, the cylinder of one end closing, and cylinder barrel is provided with perforate, and barrel covers silk screen 6；Bone
The uncovered aperture more than pipeline 7 of frame 5；Companion flange 3 is relative with the flange face of outlet(discharge) flange 2, and centre is provided with pad 8, uses
Bolt 9, nut 10 tighten sealing.Companion flange 3 is set to non-standard flange；The flange outer diameter of companion flange 3, bolt hole center's circle
The parameters such as diameter, number of bolt hole, diameter of bolt hole, bolt are consistent with outlet(discharge) flange 2.Filter element 4 will be tightly connected
Companion flange 3 is connected with outlet(discharge) flange 2 according to a conventional method, built-in facility outlet conduit coarse filter installation.
As a example by dehydration is with molecular sieve tower.
The present invention implements as follows；
The first step determines that (former caliber is for the nominal diameter of the molecular sieve tower outlet 1 not installing built-in defecator
DN100)。
Second step determines the nominal diameter (being set to DN250) of molecular sieve tower bottom outlet 1.
3rd step determines the nominal diameter of companion flange 3 perforate.Molecular sieve tower bottom outlet(discharge) flange 2 and the public affairs of outlet 1
Claim diameter identical, be DN250.Companion flange 3 is non-standard flange, mechanical discipline design publish picture.Require companion flange 3 end face
Dock with the end face of outlet(discharge) flange 2, flange outer diameter, bolt hole center's circular diameter, number of bolt hole, diameter of bolt hole, bolt etc.
Parameter is consistent with outlet(discharge) flange 2.Companion flange 3 welding end external diameter is consistent with the external diameter of rear end connection pipeline 7 and wall thickness with wall thickness.This
Device pairing flange 3 perforate nominal diameter is DN80.
4th step makes filter element 4.Skeleton 5 in filter element 4 is diameter DN100, the cylinder of length 150mm, one
End seal is closed, open at one end.The silk screen 6 selecting 40 mesh winds with one circuit outside skeleton 5, is fixed on skeleton 5.By uncovered for skeleton 5 one
End is overlying on the flange hole of companion flange 3 end face, seals fixing, filter element 4 installation.
The companion flange 3 being mounted with filter element 4 is connected by the 5th step according to conventional flange fixed form and outlet(discharge) flange 2
Connect, the function of gas coarse filtration can be realized.
When the present invention works, gas phase media carries dust granules and enters outlet 1, when filter element 4, more than silk screen
The particle entrapment in 6 apertures accumulates in the horizontal segment of outlet 1, and gas carries and passes silk screen 6 from joining less than the granule in silk screen 6 aperture
Flange 3 is spilt out next process equipment.Because filter element 4 has retained the dust granules that particle diameter is big, the downstream filter alleviated sets
Standby workload, extends the cycle of upstream device filter element replacing.
Working 1 year at molecular sieve tower in actual application, the filter element pressure reduction change that downstream is independently arranged is slow, and
Not up to change alarming value.Device parking maintenance, to the outlet companion flange 3 dismounting maintenance of molecular sieve tower bottom, finds more
Dust granules accumulates in the horizontal segment of outlet 1, therefore this filter element achieves unstripped gas coarse filtration, alleviates downstream filter and sets
The purpose of standby filter element burden.
The above, be only used for illustrating the present invention, not in order to limit the present invention, in the spirit and principles in the present invention
Within, any those familiar with the art in the technical scope that the invention discloses, any amendment of being made, replacement
And improvement, all should contain within protection scope of the present invention.
