Abstract
The invention discloses a filtering combination network capable of catching PM2.5 fine particles, and relates to the protection technique of the atmospheric environment. The filtering combination network is formed by overlapping a plurality of meshes punched with quadrilateral mesh holes and mesh hole edge filament structures and is utilized for catching the PM2.5 fine particles; the filtering combination network can be placed at an outlet of a waste gas exhaust pipe, and also can be placed at an inlet of a waste gas collecting pipe.
Description
Technical field
The present invention " can catch the filtration combinational network of PM2.5 fine particle thing " and relate to the resist technology of atmospheric environment.
Background technology
2013, in the nearly 1,430,000 square kilometres of zones of China's Beijing Tianjin and Hebei Region and the central and east, from 6 to 8,9 to 15,17 to 19,22 to 23,25 to 31 January, occur strong haze for 5 times and pollute.On February 16 to 17, on two working days after finish long holidays in the Spring Festival, occurred strong haze again and polluted.We know: our country is that " the oil-poor weak breath of a many coals " primary energy is based on the country of coal, it is again a country that 1,300,000,000 populations are arranged, many and the closely-related industry of human lives, as: thermal power plant, cement industry, steel and iron industry, chemical industry, all using a large amount of coal to be used as to produce the energy of power, carry out the work of every day every day.Because coal is not clean energy resource, so coal is discharging a large amount of greenhouse gases after directly burning---carbon dioxide, sulfur dioxide, nitrogen oxide and exhaust gas dust and PM2.5 fine particle thing in the exhaust gas dust is exactly one of arch-criminal of the current large tracts of land haze of China; In addition, in China, because the standard of the gas and oil that uses, diesel oil is not high, a large amount of sulfur dioxide and incomplete combustion are arranged and the PM2.5 fine particle thing that produces in the tail gas of motor vehicle emission; In addition, because there are 1,300,000,000 populations in China, and 48% population concentrates on the soil of 132.56 ten thousand square kilometres (account for national area 14%), these people every day eat, drink, it is 0.3 that catering industry and family kitchen are discharging a large amount of particle diameters---2 microns oil flue waste gas and fine particle thing, directly polluted The Surroundings in Cities especially.And this regional consumption of coal, economic total volume are respectively 52%, 71%.Sulfur dioxide, nitrogen oxide, tobacco powder dirt and volatile organic matter discharge capacity account for 48%, 51%, 42%, 50% of the whole nation respectively.So above reason has caused China's beginning in this year large-area strong haze pollution just to occur.This just need have new progress and breakthrough at filtering technique, could dispose PM2.5 fine particle thing from exhaust gas discharged, because PM2.5 fine particle thing is too little.
Summary of the invention
We know: filtering technique is exactly with aperture the object bigger than hole diameter to be stopped, do not allow by.So, under general thinking, want with the net sheet the tiny like this particle of PM2.5 to be stopped, just must allow the size of the aperture on the net sheet particle diameter more tiny like this than PM2.5 also little, but, actual conditions are: even such aperture is arranged on the net sheet, because it can not allow a large amount of exhaust gas discharged pass through simultaneously, it is very difficult will processing such net sheet still more.So this is difficult to directly to filter the tiny like this particle of PM2.5 with aperture.
But we know: if we filter the such fine particle thing of (seizure) PM2.5 with one " flat board ", we will be successful, because do not have the hole on " flat board ", that is to say: the size that " flat board " goes up the hole equals zero, and the particle that PM2.5 is tiny like this will be stopped by " plate ".But same problem is: owing to do not have the hole on " flat board ", just can not allow a large amount of exhaust gas discharged pass through simultaneously.So, be otiose with one big " flat board ".If we can accomplish: can stop the tiny like this particle of straight-line PM2.5, can allow again with the large quantity of exhaust gas of the such fine particle thing of PM2.5 moving linearly after removing the tiny like this particle of PM2.5, go out from other passage, wouldn't make the best of both worlds.
We must solve problem with the net sheet that is made up this structure by mesh and mesh limit silk, because it is exactly a fritter atresia, seamless, flawless " plate " that the mesh limit silk of certain width itself is arranged, it can stop the tiny like this particle of PM2.5, the stack of mesh just can form a passage that can allow large quantity of exhaust gas go out, and the shape of mesh can be the hole of different shape here.As for every net sheet can be with sheet metal material (can use the stainless steel thin slice), also can make with the thin slice nonmetallic materials.The thickness of thin slice is less than 1mm.
Problem is every networking eye and the combination of mesh limit silk on a slice net sheet, and the size of mesh limit silk is too little, the size of mesh is too big.
So the technical scheme that we adopt now is; Dashing quadrangle mesh and mesh limit silk structure arranged net sheet superposed with multi-disc, at least three forms and filters combinational network and catch the tiny like this particle (see figure 1) of PM2.5.1: the width dimensions of quadrangle mesh limit silk must be less than the size of quadrangle mesh, 2: the mesh size of quadrangle mesh and mesh limit silk structure is more than or equal to 3mm, the width dimensions of mesh limit silk is more than or equal to 2mm, 3: dashing with multi-disc then has the net sheet superposed one-tenth of same pass to filter combinational network, how much need being as the criterion with the project of using of net sheet, be example with 5 net sheets: a drift angle (55A) that intersects with two mesh limit silks of a quadrangle mesh on the 5th net sheet is as starting point, a drift angle (44A) that allows two mesh limit silks of the corresponding quadrangle mesh on top the 4th net sheet intersect is placed on above this drift angle that two mesh limit silks of the quadrangle mesh on following this 5th net sheet intersect preceding, make on two mesh limit silks of this corresponding quadrangle mesh on top the 4th net sheet and following this 5th net sheet is that two mesh limit silks of the quadrangle mesh of drift angle are parallel to each other between up and down with (55A), there be the overlapping of half of mesh limit silk width dimensions (to see Fig. 4 each other, Fig. 4---1 local amplification front elevation), with same folded method, two mesh limit silks that make two mesh limit silks of the corresponding quadrangle mesh on top the 3rd net sheet and this quadrangle mesh on following the 4th net sheet are parallel to each other between up and down, overlap, half overlapping that mesh limit silk width dimensions is arranged up and down each other, the 2nd remaining net sheet, the 1st net sheet stacks with same folded method, after having folded, these 5 net sheets, their every group filters combinational network: the mesh limit silk (2A) of namely forming every group of each mesh on the 2nd net sheet that filters combinational network, mesh limit silk (3A) with each corresponding mesh on the 3rd net sheet, mesh limit silk (4A) with each corresponding mesh on the 4th net sheet, mesh limit silk (5A) with each corresponding mesh on the 5th net sheet, width dimensions sum after these mesh limit silks are superimposed (being the 2A+3A+4A+5A sum) has been formed " plate " of a large-size, the size of " plate " greater than the size of each mesh on the 1st corresponding net sheet namely (2A+3A+4A+5A) sum (see Fig. 4 greater than the size of " 1 " (i.e. mesh on the 1st net sheet), Fig. 4---2, see over from the L direction); So more be conducive to the seizure to the tiny like this particle of PM2.5.4: use the spacer greater than zero to separate the slit that the back forms between simultaneously every adjacent two net sheets, (see Fig. 3, Fig. 3---2; 1-2; 2-3; 3-4; 4-5).
Because the quadrangle mesh on every net sheet and the combination of mesh limit silk are a pair of combining structures, so, up and down two the corresponding mesh limit silks on two net sheets between be parallel to each other up and down, overlap, half overlapping that mesh limit silk width dimensions is arranged up and down each other, also just driven simultaneously between the mesh that is attached thereto separately and the corresponding mesh and be parallel to each other up and down, overlap, half overlapping that mesh limit silk width dimensions is arranged up and down each other, after having folded, on these 5 net sheets, their every group filters combinational network: the new tunnel X that their every group of combination mesh just formed a mesh (sees Fig. 4, Fig. 4---2), can after finishing, these net sheet assemblings see inwardly by each mesh on first net sheet of this combinational network; See sideling (see Fig. 4, Fig. 4---2, LL direction): just can see the new tunnel X of a superimposed back rule mesh that forms of all corresponding meshes of this combinational network, can also see the thing of combinational network back.
The front see (see Fig. 4, Fig. 4---2, the L direction): can be clear that below this combinational network the corresponding part mesh limit silk (5A) on corresponding part mesh and part mesh limit silk (4+4A) on corresponding part mesh and part mesh limit silk (3+3A) on corresponding part mesh and part mesh limit silk (2+2A) on the 2nd net sheet, the 3rd net sheet, the 4th net sheet, the 5th net sheet each mesh " 1 " from the 1st net sheet topmost
So, when needing exhaust gas discharged by this during by the net sheet superposed combinational network that forms of multi-disc, the tiny like this particle of PM2.5 will enter into this combinational network in the eyes by each mesh on the 1st net sheet topmost, and the part mesh limit silk (4A) on the part mesh limit silk (3A) on the part mesh limit silk (2A) below the mesh that is combined layer by layer on the 2nd net sheet, the 3rd net sheet, the 4th net sheet, the part mesh limit silk (5A) of the corresponding mesh on the 5th net sheet catches even; And waste gas is just discharged from new passage X (see Fig. 4, Fig. 4---2).
