Abstract

The invention relates to a filter device consisting of a receptacle (1) comprising an inlet duct (2) and an outlet duct (3) and of a filter mesh (4) within the receptacle. The filter mesh (4) has a double wall with an intermediate space filled with a filter material layer (5) absorbing crude oil distillate.

Description

Filter device
This invention relates to a filter device consisting of a receptacle comprising an inlet duct and an outlet duct and of a filter mesh within the receptacle.
Prior art filter devices of this kind are used for removing particles from liquids. Such filter devices known per se are not usable for oil removal from water, for in¬ stance. This invention has the purpose of providing a filter device allowing separa¬ tion also of various chemicals from water. The filter device of the invention is char¬ acterised by the filter mesh having a double wall, with an intermediate space filled with a filter material layer absorbing crude oil distillate.
One embodiment of the invention is characterised by a cylindrical receptacle and a tubular filter mesh, with the filter mesh including an annular space accommodating the filter material layer. The filter material layer thus forms a circular tubular mat within the receptacle, through which the liquid to be filtered flows or is pressed evenly.
The filter mesh may contain activated carbon and a HEPA filter substance, which have a joint anti-bacterial effect.
One embodiment of the invention is further characterised by the filter material layer being amino resin and organic polymer, preferably at an approximate ratio of 53/47. All the tests have proved that the combination of the type described above purifies water, removing aircraft petrol, kerosene, mineral oil, such as "diesel/fuel oil" and lubricating oil, and also a liquid chemical tested in an experiment. Thus, for instance, a test using "diesel/fuel oil" C10-C21 and lubricating oil C-22-C40 (hydrogen fractions) mixed at a percentage of 0.1 in water, i.e. at a ratio of 50 ml/50 I of wa- ter, yielded only 0.013 mg/l and 0.014 mg/l, respectively, after filtering and purifica¬ tion. These test results give evidence of the excellent operation of the filter device in accordance with the invention.
The invention is explained below by means of an example and with reference to the accompanying drawing, whose figure shows the principle view of the filter de- vice in cross-section.
The filter device consists of a receptacle 1 , comprising an inlet duct 2 and an outlet duct 3, and of a filter mesh 4 within the receptacle. The filter mesh 4 has a double wall with an intermediate space filled with a filter material layer 5 absorbing crude oil distillate. The receptacle 1 is cylindrical and the filter mesh 4 is tubular, forming an annular space within the filter mesh, in which the filter material layer 5 is placed. The filter mesh may contain activated carbon and a HEPA filter substance, which together remove any bacteria from the liquid to be filtered. The filter material layer 5 consisting of amino resin and organic polymer removes crude oil distillates, such as fuels and oils, from the water well enough for the purified water to be re¬ turned to sea or ground water, for instance.
