Abstract

The utility model discloses a high efficiency filter core type deduster, comprising a settling chamber and a filtering chamber. The utility model is characterized in that the air inlet of the settling chamber is provided with a guide pipe which is extended into the inner part of the settling chamber, the filter layer of the folding filtering cylinder of a filter core in the filtering chamber is composed of outside ultrafine glass fiber and organic fiber mixed layer, an inside organic fiber layer, and inner surface and outer surface organic films. As the utility model is added with the guide pipe, the air flow short pass phenomenon can be avoided; as the novel filtering layer is designed, the sufficient high filtering efficiency can be ensured, the sufficient resistance and smaller resistance force can be provided, and the structure, the manufacture and the assembly are simpler.

Description

A kind of efficient filer element type deduster

The utility model belongs to the udst separation technical field, is specifically related to a kind of efficient filer element type deduster.

In industries such as chemical industry, cement, tobacco, metallurgy, contain a large amount of dust in some workshop air, usually use sack cleaner, cyclone separator, water film dedusting equipment etc. to carry out dedusting, these dedusters are used for dust of different nature respectively its characteristics, but generally speaking desirable not enough.Provided a kind of filer element type deduster in the prior art, its floor space is less, convenient operating maintenance, but its expansion chamber air inlet and gas outlet are at a distance of too near, be easy to generate the air-flow short circuit and influence filter efficiency, the structure of the fold cartridge filtering layer of filter core and manufacturing are all complicated in its filter chamber.

The purpose of this utility model is to design the efficient filer element type deduster that a kind of structure, manufacturing and assembly technology are all simple, air-flow is difficult for short circuit.

Design of the present utility model is as follows, comprise expansion chamber and filter chamber, the air inlet that it is characterized in that expansion chamber is provided with the guide pipe that stretches into expansion chamber inside, and the fold cartridge filtering layer of filter core is made up of ultra-fine fibre glass, organic fiber mixed layer, the organic fiber layer of inner face and organic film on inside and outside surface of outside in the filter chamber.

The utility model has been owing to added guide pipe, thereby avoided the air-flow short circuit, and the structure of fold cartridge filter material had both guaranteed sufficiently high filter efficiency, had enough intensity and less resistance again, and its structure, manufacturing and assembling are all simpler.

The utility model has following accompanying drawing:

The efficient filer element type filter structure schematic representation of Fig. 1

Fig. 2 filter partial cutaway schematic

Fig. 3 filter core schematic diagram

Fig. 4 filter core filter medium structure schematic diagram

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1, Fig. 2 are the utility model structural representation, comprise expansion chamber 2 and 4 two large divisions of filter chamber, the air inlet 19 of expansion chamber 2 is provided with guide pipe 1, guide pipe 1 can be welded on the air inlet, also can be connected on the air inlet by flange, inlet air flow is flung, in order to avoid the side ports 3 from dividing plate 23 is shorted to filter chamber 4 downwards.Under the inlet air flow towards the time because the effect of gravity and inertia force makes the grit more than 10 microns fall into the bottom, enter disposal box 7 by ash-valve 6.The side ports 3 that the air communication of coming up from expansion chamber bottom recoil is crossed on expansion chamber and the filter chamber's common partition 23 enters filter chamber 4.Filter core 8 in the filter chamber 4 is supported by steel skeleton 24, and the outside, filter chamber is provided with lid 25, is used for more renew cartridge 8.Air becomes cleaned air after filter core 8 filters, dust is attached to the outer surface of filter core 8, and cleaned air is then discharged by outlet 12.When the dust of cartridge surface runs up to certain thickness, when the filtration resistance increases to certain setting value, by differential pressure pickup 10 number of value is sent to PLC electric controller 11, control magnetic valve 9 makes compressed air spraying filter core 8, blow the dust that accumulates on the filter core successively off, make pressure reduction recover normal, air filtration is carried out as usual.The dust that is trapped or blows off drops to the bottom, filter chamber, enters disposal box 7 by ash-valve 5.

Fig. 3 is the filter core schematic diagram, and wherein filter cylinder 13 forms by filter material is folding, and upper and

lower end cap

14,15 casting epoxy resins or polyurethane and filter cylinder and inside and

outside wire netting

17,18 are fixing, upper end cover 14 sticking rubber gaskets 16.

Fig. 4 is the utility model structure of filtering layer schematic diagram, and it is made up of organic film 22 of the organic fiber layer 21 of the ultra-fine fibre glass of outside, organic fiber mixed layer 20, inner face and surfaces externally and internally.Organic fiber in the mixed layer 20 can adopt polyvinyl or the terylene or the polypropylene fibre of 10～15 microns of diameters, and it is 1～5 micron flocculence short fiber that ultra-fine fibre glass can adopt diameter, and the two respectively accounts for 50% (weight ratio).The organic fiber of organic fiber layer 21 can adopt polyvinyl or the terylene or the polypropylene fibre of 10～15 microns of diameters.Organic fiber layer 21 and mixed layer 20 are integrated by hot sticky, for example can be hot sticky down at 110～150 ℃.The filtering layer of this structure has enough support strengths, simultaneously less resistance and high filtration efficiency is arranged also, and its filter efficiency can reach 99.999%.Organic film 22 is that mixed layer 20 and the organic fiber layer 21 that will be integrated soak antiseized, the antistatic skin covering of the surface that the back drying forms in soak, can also increase the adhesion of fiber after the immersion.Soak can adopt alcohol, acetone etc. as organic solvent, adopts epoxy, phenolic aldehyde, polyvinyl butyral resin etc. as solute, and its concentration is about 1%.

Mixed layer 20 thickness of the present utility model are 0.1～0.15 millimeter, and organic fiber layer 21 thickness are 0.15～0.2 millimeter, and for well, organic film 22 thickness are 0.8～1.2 micron to the two gross thickness in 0.3 millimeter.

In order to reduce resistance, guide pipe 1 of the present utility model can adopt filtering material to make, and for example can adopt the structural material similar to the filter cylinder filtering layer, also can be made by casing play and screen pack two layers of material.
