Abstract

Organic absorbent geotextile modified as an infinite fleece band and consisting of at least one layer of non-woven textile in the structure of which there are dried, combed out and squeezed duck feathers inserted by needling procedure. The outer geotextile walls consist of non-woven textile in a form of a sieve or of porous non-woven textile. At least two layers of non-woven textile are joined on longitudinal sides of the band to create a sleeve.

Description

Organic absorbent geotextile
Field of Engineering
The invention relates to organic absorbent geotextile in a form of an infinite band of fleece.
State of the Prior Art
Hitherto well known commonly used absorbents to catch crude oil substances have loose consistency. The microporous granulate e.g. VAPEX which is very effecticve to catch crude oil substances on solid subjacent e.g. roads and on stagnant water surfaces etc. as well is mostly known of them. It is not suitable to be used on running water flows. Its removal is very expensive and difficult from the ecological point of view. To remove crude oil substances a supporting plant is known in a form of a porous bellows filled with sorbent which can be waterfowl feathers e.g. This supporting plant is modified to contain an inside porous exchangeable bellows. The solution is known from the patent files no. EP 92922751.
Substance of the invention
Organic absorbent or sorbent geotextile, respectively, according to the invention, is arranged into an infinite fleece band. The substance is rooted in that it consists of one layer of non-woven textile in the structure of which dried and combed out and squeezed duck feathers are retained as a result of needling procedure. The outer geotextile walls consist of non-woven textile in the form of a sieve or of porous non-woven textile. At least two layers of non-woven textile are joined on longitudinal sides of the band.
The advantage of the solution in accordance with the invention is the facility of absorbing or sorbing geotextile respectively to let water pass through and, at the same time, to absorb organic substances based on polypheniles and polyolephines by which water had been contamined. This is given by making use of duck feathers the structure of which guarantees the absorbing facility. Therefore, the geotextile can be used to remove crude oil substances on water surfaces. The geotextile, if having been used in such a way, can be easily removed ecologically because of very light handling.
In the structure the non-woven textile guarantees resistance and the geotextile can be wrapped up and transported. It is suitable to be destroyed by burning. Other suitable application is to use it as a packing piece for catch pits in filtration units of pumping plants and service stations and, equally, in the same way in other plants of petroleum chemical industry, i.e. in locations where water contamining petroleum products are to be removed.
Further, it can be used in places where heavy machines are set to work, e.g. in building sites. Here the organic absorbing geotextile can serve as a hindrance against random environment contamination by crude oil products. For the same reason, it can be used as a filtering stuffing box in sewerage bridge inlets and oil catchers.
Making use of waste product of duck slaughter houses presents a non-negligible advantage of the solution in compliance with the invention.
Examples on Invention Embodiment Example no. 1
A crude oil stain on water flow surface has been removed by organic absorption geotextile according to the invention.
Several 10 m long and 2 m broad bands, formed of one layer of non-woven polypropylene textile, were used. In the structure of this porous textile the squeezed, dried and previously combed out duck feathers had been inserted by needling procedure. Due to the geotextile structure the duck feathers are situated on both geotextile side surfaces and the non-woven textile forms a matrix.
The duck feathers are combed out in order to improve absorbing geotextile properties and they are squeezed in order to be more densely fastened by needling procedure.
Example no. 2
According to the investion, the organic absorbing geotextile had been prepared. Two one-layer bands of non-woven textile, in the form of a sieve, were used the longitudinal walls of which are joined. In the sleeve, made in such a way, the dried, combed out and squeezed duck feathers were located.
Utilization in Industry
Organic absorbent or sorbent geotextile, respectively, can be used to clean waste water, advantageously flowing water, containing crude oil substances.
