Definitions

  • the invention relates to methods for producing oil filter mats for filtering gases and liquids
  • a newer type of oil binder is a rubber mulch (described, for example, in German patent specification 40 07 695, adsorbent and binder for oils, filed on 10 3 1990).
  • This ground rubber mulch is usually made from industrial rubber (eg old tires) without chemical additives Suction is spongy, since this rubber mulch has a much larger surface area than normal rubber granules. For example, you only need approx. 200 - 280 g rubber mulch to bind 1 liter of oil.
  • all types of rubber mulch can be used for the invention “Rubber flakes” (mulch-like chip, crumble, flour and / or flake-shaped rubber particles, possibly also foamed) understood, which have a larger surface than smooth rubber grains and are suitable as oil binders. They contain a high proportion of pores, so that they are even floatable can, is inexpensive, environmentally compatible and easy to dispose of
  • the aim of the invention is to develop a large-area packaging or carrier layer for such rubber mulches, which produces a uniform filter or adsorption layer and a high absorption capacity of the filter
  • the invention therefore relates to a multilayer flat filter for filtering and / or absorbing gases and liquids, consisting of at least 2 large-area boundary layers, at least one of which is gas and / or is liquid-permeable and an intermediate filter layer, characterized in that the filter layer consists of ⁇ eselfahiges rubber mulch or a mixture of rubber mulch with other filter materials and the outer surfaces of the boundary media between the surrounding and cut edges are at least partially fixed directly or via intermediate layers
  • These limiting media are preferably made of nonwovens, but can be made of any suitable type of fabric, membrane, film, knitted fabric, paper.
  • Cardboard, foam plastics or other textiles or their combination are made and are permeable to air or water on at least one side of the rubber mulch layer, so that gases and / or liquids can come into contact with the rubber mulch and / or through the rubber mulch layer
  • the limiting media can consist of any suitable raw materials, opening widths and any flat masses or combinations thereof.
  • Such a product is also characterized by its flatness with a thickness of preferably approx. 2 mm to approx. 5 cm, but without being restricted to it that the boundary layers are fixed to each other without the use of adhesives or thermal fixation between the boundary media introduced sem
  • the intermediate layer made of rubber mulch can also be incorporated in a mixture with other materials and thus also vary the main application, whereby the relatively light rubber mulch can also be present in a significantly minor amount (e.g. 0.3 kg / m 2 rubber mulch + 3 kg / m 2 Sand, or 0.2 kg / m 2 rubber mulch + 1.5 kg / m 2 activated carbon + 0.1 kg / m 2 reinforcing thread, or 2 kg / m 2 rubber mulch + 0.3 kg / m 2 coarse fleece, or 2, 5 kg / m 2 rubber mulch + 0.3 kg / m 2 wire mesh + 0.3 kg / m 2 adsorbing resin particles) Furthermore, the addition of zeolite, foam particles, cork, thread made of natural and artificial fibers, bentonite, spacers, ash, Wood chips, aerated concrete particles, hydraulic binders.
  • zeolite, foam particles, cork, thread made of natural and artificial fibers bentonite, spacers, ash, Wood chips
  • 01 can be separated from solid, liquid and gaseous media and absorbed or absorbed (e.g. by concrete, water or exhaust air).
  • Various other liquids such as petrol, alcohol, chlorinated hydrocarbon, acetone, aromatic can also be used Solvents, heavy metal solutions, etc. can be sucked up.
  • it can be designed as a floating or diving body (for example as a floating body on a grease-contaminated water surface in a grease separator with a dry activated carbon mat above it as an odor absorbent or directly with a mixture with water-repellent activated carbon), because of its thermal insulation or soundproofing and / or sealing properties are used, etc.
  • the filter can also be folded in the shape of an accordion, in order to multiply the passage area
  • constituents can be filtered out of the air or water if the rubber mulch filter is rolled up like a hose - with an impermeable layer on the outside - and the medium to be filtered is allowed to flow inside the hose. If the filter medium flows along the inner walls, it continuously comes with the Rubber mulch surface in contact and is thus filtered (like on an intestinal wall)
  • a similar variant is created by folding the rubber mulch filter like a round air filter in a car and inserting it into a hose, whereby the medium to be filtered can flow along or - as a two-chamber system - must pass through it
  • the filter can be used very well in the groundwater area.
  • the rubber mulch binds oil and fat-containing components, the activated carbon binds further harmful groundwater pollution.
  • the proportion of the rubber mulch should should not be too high, as this would otherwise impede the water flow of the filter
  • a suitable filter When used under endangered containers, a suitable filter can filter, absorb and / or retain an escaping liquid until the fire brigade arrives, whereby the groundwater flow - in contrast to conventional seals - is not completely interrupted and there is also a possible risk of buoyancy (as is often the case with groundwater seals) ) is prevented
  • the groundwater can also be protected from escaping and harmful liquids. Additionally, the filter can increase the stability of the railway body by choosing the appropriate tensile strength and elasticity of the materials increase significantly and also act as sound damping due to the spring action of the rubber mulch
  • the oil suction mat can also be placed under, for example, track-laying machines or locomotives between and next to the tracks in order to catch dripping 01
  • a filter of this type can also be flowed through in multiple layers dimensioned rectangular shaft, by folding the layers in the manner of an accordion-like layer.
  • a 10 cm thick layer from a 1 cm thick rubber mulch filter into a 0.5 x 0.5 m shaft, it is 5 m long and 0.5 m wide, flow-through filter necessary, which no longer has to be cut in layers during installation.
  • the rubber mulch is usually used in combination with other ⁇ eselfahliche materials, such as activated carbon
  • the flat rubber mulch filter can also be wrapped around the perforated tube one or more times and flowed through perpendicular to its plane
  • the oil-saturated rubber mulch can be burned relatively easily after use if suitable packaging or fixing materials (eg polypropylene on both outer sides) are used.
  • suitable packaging or fixing materials eg polypropylene on both outer sides
  • the fixed oil and / or gasoline can be recovered by pyrolysis
  • An example (see FIG. 1) of such filters can be that a dry rubber mulch layer made of ⁇ eselfahirable rubber mulch (2) in a in about 200 g / m 2 nonwoven (thermally or by needling, bonding, etc.) as a base (1) Amount of approx. 2 kg / m 2 is applied.
  • a second non-woven layer (3) with again approx. 200 g / m 2 made of needled material as a cover (possibly approx.
  • the package is then needled in a needle machine, that is to say ten thousand times (preferably 5-120 punctures / cm 2 ) per needle by means of barbed needles, thread of the needle needle (3) is guided through the activated carbon layer (2) to the underside (1), where swallow the thread with the underlay fleece (1) and thereby hold the individual layers (1, 2, 3) together.
  • the product can be needled a second time from the underside (1) and / or the bottom on the other hand, be treated thermally or with adhesive.
  • the principle of such a process is described, for example, in EP 0 278 419 A2, filed on 5 2 1988, but pure bentonite is used as an intermediate layer
  • the production width can, for example, be approx. 5 m (but without being limited to it), whereby smaller widths can be created before the winding by longitudinal cuts. After winding, the webs can still be cut so that handy surfaces are formed to allow the mulch to flop out at the edges To prevent this, rubber - mulch - free strips can be provided in the production process, along which slitting is performed. Furthermore, the edges can be glued, glued, welded, looped over, sewn, etc
  • a further variant (see FIG. 2) of the product arises from the fact that a coarse vhes with rubber mulch (5) is applied to a Vhess layer (or fabric, knitted fabric) (4) and is needled into the lower layer so that the rubber mulch does not fall out of the coarse fleece , a water-impermeable membrane (or non-woven fabric,) (6), possibly with the help of other materials, is welded or glued to the thread protruding from the activated carbon / coarse layer.
  • a product can be, for example, with the membrane (6) down under oil-dripping machines
  • the rubber mulch (5) soaks up the 01 and the Membrane (6) guarantees that kem 01 gets through to the base.
  • the oil suction mat can be folded up and disposed of by additionally fixing quartz sand, for example, to the fleece surface (4), making such a product even easier to walk on and drive over (abrasion, non-slip and UV resistant)
  • an oil- or water-impermeable product can be produced by, for example, a rubber-mulch mixture (8) being sprinkled between the knobs in the factory by a knob-shaped embossed membrane (7) and the knob ends protruding from this mixture being fixed with a covering fleece ( 9), for example by gluing or welding, are connected in points.
  • the base (7) is at the same time the spacer to the cover layer (9), which can also consist of a woven fabric, knitted fabric, etc.
  • the water-impermeable membrane (7) creates a Product in which the rubber mulch (8) can only come into contact with the filter medium on one side (9) D h, this filter is suitable for the tube variant described above.
  • the membrane (7) can, however, also be perforated, so that the entire product can be flowed through This is also achieved in that a nonwoven cover layer (9) is connected to the knob membrane (7) by needles
  • FIG. 4 Another variant (see FIG. 4) of such a product arises from the fact that one on a fleece (10). e.g. by melting or gluing, the fixed mesh (1 1) is filled with rubber mulch (12) To cover it, a fleece (13) is fixed on the top of the mesh.
  • the mesh (1 1) mainly serves as a spacer, so that the Rubber mulch (12) inserted into the cavities is not pressed together, thereby permitting the entire product to be highly permeable to air or water.
  • Such a mat can be used, for example, to clean exhaust air containing oil.
  • the mesh (11) other materials, such as plastic, can be produced in the same way -Wire mesh, can be used
  • a fleece (14) glued or melted onto a scrim (15) is used as a base.
  • the fleece side (14) comes to lie at the bottom and in the scrim (15) is filled - possibly by shaking - rubber mulch flakes (16) (e.g. 0.2 - 5.0 mm diameter) so that the top of the scrim (15) still protrudes from the rubber mulch layer (16) to cover a second fleece (17) glued or melted onto the protruding threads of the random lay-up (15).
  • the random lay-up (15) usually consists of approx.
  • this variant is also that the rubber mulch (16) can be introduced relatively loosely, which reduces the flow resistance of the filter.
  • larger thicknesses can be achieved with this variant than with the previously described needling and also grid variant instead of the boundary fleeces (17 , 14) other materials such as woven fabrics, knitted fabrics, foils, etc. can also be used
  • the P ⁇ nzip remains the same if, instead of the random scrim (15), other types of spacers such as 3-dimensional nets, knobs, plastic balls, discs or the like made of, for example, foam, PP, PEHD, etc. from other materials such as expanded concrete, Wood etc. are used. Needlable particles such as foam spheres can also be used in the previously described Nadelva ⁇ ante as spacers mixed into the rubber mulch layer (16) and also change the flow resistance there
  • the rubber mulch tends to trickle out more or less from the side. With the needling needles, this risk is not particularly great, since the needling thread passing through the rubber mulch layer also fixes the rubber mulch flakes to the side. However, with other variants with e.g. pimples or tangles, this tendency is greater
  • a narrow strip of material can be inserted in the production direction instead of the rubber mulch layer in the side or intermediate cuts in the production direction, which limits the rubber mulch layer to the outside. If it has been inserted in between, it can also be cut slowly and thus again seals the resulting ones Cut edges
  • Such a material can be a fleece strip (preferably 5 - 25 cm wide and 2 - 30 mm thick).
  • the fleece strip additionally has one or more layers of foal, the rubber mulch filter along the cut edges becomes difficult to flow through and the medium to be filtered must pass through the Flow through the rubber mulch and cannot escape laterally into the (rubber mulch-free) edge area.
  • Side and intermediate strips can also be easily made without rubber mulch during production, whereby the end product] becomes thinner on the side than in the middle section
