Description

Device for collecting and discharging liquids and / or gases leaving a watercourse

The invention relates to a device for collecting and discharging emerging from a body of water liquids and / or gases or a liquid-gas mixture, in particular emerging from a river bed of crude oil or natural gas. The field of application of the invention also extends to the collection and discharge of uncontrollably discharged from liquids discharged into the body of water devices or gases.

From US 3,548,605 A a device for collecting and discharging a submerged emerging oil-natural gas mixture is known, which has a downwardly open collecting bell, which is placed sealed on the seabed above the respective leakage and to which a bellows-like trained, connects to the water surface reaching delivery line. The collecting bell has floats, so that they can be drawn floating in the water over the exit point of the crude oil-gas mixture and then lowered by filling the Schwimmkör ^¬ per with ballast until the edge of the downwardly open collecting bell rests tightly on the seabed , The floats consist of surrounding the edge of the collecting bell tubes, which are filled via hose lines with ballast liquid.

The collected by means of the collecting bell oil-natural gas mixture is passed through the delivery line to the water surface and passes here possibly through another line to a ship from which the mixture is taken and on a Separartion of petroleum-natural gas mixture by the delivery line entrained seawater takes place.

From DE 2941 228 C2 another device is known, which has a down to the outlet point of a petroleum-natural gas mixture, downwardly open collecting bell, wherein on the collecting bell, a separator for the separation of three phases is arranged so that it the collecting bell forms a unit and the collecting ^¬ bell is connected to the bottom of the separator and this is exposed to the hydrostatic pressure of the overlying water column. The separated phases of the collected crude oil-natural gas mixture are discharged after separation individually from the collecting bell or the separator. From DE 2941 228 C2, another device is also known, which also can be lowered to the exit point of a petroleum-natural gas mixture downwardly open collecting bell has, however, followed by the collecting bell, a delivery line through which the collected mixture is passed to a spaced apart from the collecting bell arranged 3-phase separator. The separator can be arranged in beliebi ^¬ ger height between the collecting bell and the water surface.

Another device is known from DE 2952 399 C2. This device has a designed as a hollow body downwardly open, downwardly funnel-shaped widening hood. The hollow body of the hood is with inlet or

Outlet openings provided for ballast. The hood can be transported floating in the water to the point of exit of the petroleum-natural gas mixture and lowered here by filling the hollow body of the hood with ballast until the lower edge of the hood rests tightly on the bottom of the water. At the upper, funnel-shaped eingezoge ^¬ edge of the hood, an inflatable bladder can be arranged, which can be sealingly brought to a protruding from the water body pipe end, for example, a submerged under water defective conveyor pipe, for conditioning. The specially designed ballast space of the hood, for example in the form of individual chambers that can be filled or emptied separately with ballast, allows a good and secure positioning of the hood on the river bottom. The ballast is conveyed via possibly separate ballast lines to the ballast chambers.

However, it has been found that the devices known from the prior art are not sufficiently flexibly applicable for practical applications and are in part structurally very complex. The object of the invention is therefore to provide a device for Auffan ^¬ conditions and dissipation of leaking from a body of water liquids or gases or a liquid-gas mixture that is flexibly applicable and structurally simple. The solution to this problem is achieved by a the features of claim 1 aufwei ^¬ sending device. The claims 2 to 8 describe advantageous Weitererbil ^¬ tions of the device according to the invention.

A device according to the invention for collecting and discharging liquids or gases emerging from a body of water consists of a plurality of tube-type assemblies that are essentially structurally identical to one another and are tubular. Each module forms a hose section made of flexible fabric. At the two open ends of the module forming a tube section, the opening is surrounded by a respective flange. Each module forming a tube section has stabilizing rings extending along the circumference of the tube wall, which are arranged in the longitudinal direction of the module at a distance from one another which is smaller than the diameter of the module. Wetterhin is formed in the tube wall of each hose section forming a module Druckausgleichsöff ^¬ tion. Each module has means for attaching lifting or driving bodies. The individual modules each forming a tube section are joined together to form a tube system, that means are at least each in the region of the joint of two modules and at the ends of the hose system for attachment of up- or stripping bodies and that at the bottom, the waterbody facing open At least one pressure equalization opening is located at the end of the hose system. The particular advantage of the inventive device consists in their simp ^¬ chen modular structure and the possibility of a variety of each one

Hose module forming modules by means of the front side mounted flanges to assemble a nearly arbitrarily long hose system, each module has an inherent rigidity, which complement each other to a total rigidity of the hose system. The hose system can be adapted to different water depths and flow conditions. The modules are due to their nature of flexible fabric and their construction with circumferential around the circumference stabilizing rings in the longitudinal direction, foldable and therefore easy to transport and save space. They allow good logistics to Systemvor ^¬ entertainment for unplanned applications due to their essentially the same structural design.

For lowering and stable positioning of the hose system in a body of water at each a hose section forming module up or

Output body are each attached with such an up or down force that the corresponding module is held in a predetermined depth of water in the balance. As a result, the tube system as a whole can be stably and substantially vertically positioned in a body of water. Preferably, the means for fixing the drive or driven body are arranged on the end face openings of a module surrounding flanges.

In addition, retaining tabs can be arranged on the hose wall of a module for attaching additional drive or driven bodies. These retaining tabs Of course, they can also serve for a different attachment of the hose system.

The tube wall of a hose section forming module is preferably made of a composite material, particularly preferably a composite fabric, such as a textile-metal or a textile-plastic fabric.

It is also essential to the invention that a pressure compensation opening is formed in the hose wall of each module. This pressure equalization opening can be designed as a non-return valve, which is designed so that water can flow into the interior of the hose system, however, the fluids and / or gases conducted in the hose system can not leave the hose system through the pressure equalization openings. Due to the pressure equalization openings, the tube system becomes pressure-neutral, i. each arranged along its longitudinal axis inner and outer pressure of a nearly perpendicular in a body of water

Hose system are the same.

An inventive device for collecting and discharging emerging from a body of water liquids or gases is operated druckneutrai. The direction of the liquids and / or gases in the tube system is effected in addition to the impulse at the outlet of the liquids and / or gases from the body of water exclusively by the buoyancy force.

In the tube wall of the lower, the waterbody facing the last module of the hose system can be introduced distributed around the circumference several Druckaus ^¬ same openings.

In a preferred embodiment, the Schiauchwand the lower, the

Water body facing the last module of the hose system facing the water bottom lower opening of the hose system annularly formed aus elastically material to be along the circumference of the hose wall uniform contact on the water bottom to the outlet Stelie the liquids and / or gases to reach from the water bottom.

In another preferred embodiment of the side facing the body of water the last module of the tube system can be disposed around the the seabed supplied ^¬ turned opening distance elements in the direction of water body reason. These spacers prevent the lower end of the hose system, which faces the water bottom, from being placed on the bottom of the water. They hold the open end of the hose system at a preselected distance above the water bottom. As a result, an annular pressure equalization opening is formed directly around the lower opening of the hose system facing the water bottom, through which water can flow into the hose system.

For catching and discharging liquids and / or gases emerging from the bottom of the water, at first so many modules each forming a hose section are joined together to form a hose system such that its length suffices for the water depth at the corresponding point. At the individual modules of the hose system are up to the funds provided or

Output body attached with such an up or down force that the hose system aligns almost perpendicular to the water. In this case, a pressure equalization takes place via the pressure equalization openings, so that the hose system assumes a pressure-neutral state along its length. Thereafter, the hose system is positioned so that its lower, the bottom of the water facing opening over the body of water around the exit point of the liquids and / or gases, this may also be a protruding from the body of water pipe end of a defective delivery line is. By attaching further drive or driven body to the modules of the hose system, this is further lowered until the tube wall surrounding the lower opening of the hose system rests on the bottom of the water, or stand up the lower opening surrounding spacers on the bottom of the water. The lower, last module of the hose system can be additionally anchored by retaining elements on the body of water.

The liquids and / or gases or mixtures of liquids and gases emerging from the watercourse rise in the hose system due to buoyancy forces due to differences in density between the liquids and / or gases leaving the watercourse and the water of the watercourse. In this case, water sucked in through the pressure compensation openings is conveyed upwards. At the located on the water surface upper opening of the hose system, the liquids and / or gases, possibly also mitgefördertes water, aspirated and further processed or processed.

In addition to the procedure described above for joining together and for positioning the hose system for collecting and discharging liquids and / or gases emerging from the body of the water, it is of course also possible first to position a single or an assembled group of modules by attaching driving or driven bodies and possibly anchored to the riverbed and then to position other modules individually or in groups in the body of water under attachment or stripping bodies and on add the previous modules until a rich to the ^surface of the water ^¬ the hose system is formed.

The invention will be explained in more detail with reference to an embodiment. The accompanying drawings show in

At the two open end faces of the module forming a tube section 1, the two openings of the module surrounding an upper flange 3 and a lower flange 4 are arranged, wherein the

Hose wall 2 by means of clamping rings 5 is attached to the flanges 3, 4. On the tube wall 2 extending stabilizing rings 6 are along its circumference. The stabilizing rings 6 are arranged in the longitudinal direction of the module 1 at a distance a from each other, which is smaller than the diameter D of the module 1. Likewise, the distance of the upper or lower flange 3, 4 next stabilization ring 6 to the respective flange 3, 4 is smaller than the ^{diam ¬} D of the module d. 1 In the tube wall 2 of the module 1, a pressure compensation opening 7 is formed. The pressure compensation opening 7 is arranged in the vicinity of the lower flange 4. Eyelets 8 are mounted on the flanges, distributed over the outer circumference of the flange plates, as means for fastening lifting or expelling bodies 9.

FIG. 2 shows a hose system assembled from a plurality of modules 1 forming a hose section. The number of modules 1 is chosen so that the length of the floor also corresponds to the system of water depth. The single ones Modules 1 are screwed to the flanges 3, 4 and so firmly connected. To the bottom of the water 10 facing opening of the tube system, that is on the bottom of the water 10 facing last module 1 spacers 1 1 are arranged, which point in the direction of the bottom of the water 10 and stand with its free end on the body of water 10. They hold the lower, the body of water 10 facing open end of the hose system at a preselected distance above the water bottom 10 so that an annular pressure equalization opening is formed around the lower, the waterbody 10 facing opening of the hose system through which water can flow into the hose system. The arrows 12 are intended to clarify the water flowing into the hose system. Likewise, to balance the pressure along the length of the hose system or the depth of the water through the pressure compensation openings 7 located in each module 1, water can flow into the hose system. The lower opening of the hose system is positioned above the body of water 10 so as to cover the location from which liquids and / or gases escape from the body of water 10. The lines 13 illustrate the emerging from the water ^¬ grund 10 and flowing into the tube system fluids and / or gases.
