Definitions
- the invention relates to a filter for removing hydrophobic substances according to the preamble of the main claim.
- DE-Cl 36 17 995 discloses a process for removing silicone or polymeric fluorocarbon-containing impurities from aqueous emulsions or dispersions, it being proposed that the aqueous emulsion or dispersion be finely divided silicates sand, diatomaceous earth, Silica gel or quartz is filtered. The structure of such a filter! " Direction is not described in this reference.
- a filter insert for a liquid filter which essentially consists of a liquid-permeable support tube, a filter cartridge being pushed onto this support tube.
- This filter cartridge has a net-like cylindrical frame inside, which is surrounded by a fiber packing. With such an arrangement it is not possible that the electrolytic leaks and the like.
- the invention has for its object to remove fats, oils, silicone and perfluorinated compounds as well as solids from electrolytic lacquers without having to fear production disruptions due to frequent clogging of the filter devices. • This object on which the invention is based is achieved by the teaching of the main claim.
- a filter which, if necessary, can be combined with other systems, such as ultrafiltration, heat exchangers, etc.
- a spiral module-shaped filter cloth body is used, in which an approximately 2 m large propylene film and the like. U. wound up in two layers and housed in a corresponding needle fi z bag.
- the nonwoven web can be wound around a perforated support tube together with a coarse-mesh plastic network.
- Filter modules or filter cartridges are only necessary once or twice a week.
- Flake-shaped polypropylene fibers or glass fibers can be placed between the actual spiral filter cartridge and the filter bag in order to avoid blockage of the filter bag.
- a filter is shown purely schematically, partially cut open, the adsorption fleece with its support grid being more clearly recognizable in a pulled-out representation.
- a housing 1 of a filter is drawn, the outflow of this filter housing 1 being recognizable at 8.
- the provided in the upper region Zuflu3 is not shown for reasons of clarity and the guided through the housing 1 medium flowing / St from the top in the longitudinal axis of the housing 1 downward and penetrates a housed in the housing 1 filter cartridge 7 transverse to the aforementioned longitudinal axis.
- a support basket 2 is provided within the housing 1, which carries a filter bag 3 on its inside, which is designed as a needle felt filter or monofilament bag and has the task of retaining solid particles.
- a support tube 4 provided with throughflow openings.
- This filter cartridge 7 essentially consists of a support grid 6 and an adsorption fleece 5, it being possible for the adsorption fleece 5 to be formed from polypropylene fibers or glass fibers.
- the adsorption fleece 5 can also be applied in two or more layers.
- the support grid 6 consists of a coarse-meshed plastic network, preferably a fiber structure, which only has the task of mechanically supporting the adsorption fleece 5, but at the same time, since it lies in the direction of flow in front of the adsorption fleece 5, causes coarser impurities to be retained.
- a space 9 is present between the spiral filter cartridge 7 and the inside of the filter bag 3.
- This space 9 can additionally be filled with filter materials.
