Description

Method of filling a module system of fluid receiving containers and emptying them, and using one or more containers

The invention relates to a method for filling a modular system of fluid receiving containers and emptying the same, wherein the containers are arranged in a body of water and each container has an inlet and a drain for the fluid. The invention further relates to a new use of one or more containers.

The fluid receptacles may be located partially or completely in a body of water, e.g. also floating.

The fluid to be received by the modular system of containers may be mixed water. In a sewage network, which absorbs both waste water and rainwater, it can come especially in heavy rain to increased accumulation of mixed water. Since the absorption capacity of the sewerage system, which are connected to the sewerage system, is limited, mixed water receiving containers are provided, in which the receiving capacity exceeding mixed water amount is passed. The mixed water is stored in the receptacles until the sewer system at a later time again have enough capacity to absorb, for example, by decreasing rain, the mixed water drop. In order to reduce the space requirement of such fluid receptacle is proposed in DE 103 38 419 Al to arrange them floating in a body of water or immersed therein. It is expedient to use the fluid receptacle in the vicinity of an inlet of the sewage network in the bank area of the water. Thus, a sewer system, which is not yet provided with mixed water storage tanks for intermediate storage of the mixed water, can be retrofitted in a simple and cost-saving manner with such containers.

Nevertheless, the installation of fluid receptacles in a body of water is not inconvenient. Especially in the empty state, when no fluid is stored in the containers and the containers are provided for receiving fluid, it acts on a strong buoyancy. Therefore, the containers must be kept by a suitable foundation, by a large weight or by attaching a load on the water bottom, said measures must be sufficient overall to withstand the strong buoyancy force with sufficient security. The previously proposed solutions prove to be in their technical design and cost still too costly to convince economically.

The object of the present invention is to provide a fluid receptacle to be mounted in a body of water in an optimally simple manner and to keep it at the bottom of the water.

The object is achieved in that in a method for filling a modular system of fluid receptacles and emptying the same of the type mentioned, the container further provided with an inlet and outlet for the ambient water of the water, at least a portion of the container with ambient water of the Water is filled when there is no need to take the fluid through the module system and no partial filling of the same by the fluid and the ambient water is pumped from at least part of the container filled with it in the water, if Need to accommodate the fluid through the modular system.

Due to the method according to the invention, the buoyancy of the fluid receptacle can be significantly reduced by a number of containers are always filled with the fluid and / or the ümgebungswasser the water. The number of containers filled with fluid and / or ambient water, depending on the weight of the containers, may be predetermined such that the remaining buoyancy by the possibly empty containers provided for receiving further fluid is compensated by the total weight of the containers. The containers can then be kept safely by a relatively inexpensive foundation on the bottom of the water, since the foundations no longer have to absorb the buoyancy forces of the container.

In the event that due to the possibly emptied container and / or unnecessary weight saving a resulting buoyancy force remains, but which is reduced according to the invention, this can be compensated by the foundation of the container on the water bottom, the foundation can also be accomplished without much effort can. Depending on the found sediment layers of the waterbed, a simple deep or flat foundation is sufficient.

Conveniently, it can be provided to fill each container always only with fluid or with ambient water, but not to mix both in a container. In special circumstances, however, it may be advantageous to include both liquids in the container.

The containers forming the modular system may be interconnected by overflows such that, when one container is filled with fluid or ambient water, the fluid or ambient water flows into the next adjacent one.

In a preferred development of the invention, the number of containers filled with ambient water from which the ambient water can be used to provide a volume for As the fluid is pumped off, depending on the particular need for the inclusion of the fluid to be controlled by the modular system. For mixed water storage tanks, regulation can be by connection to the urban pumping station. If there is a notification that a discharge event is to be expected, ie the inflow of mixed water into the water in a heavy rainfall, depending on the size of the discharge event with the emptying of a corresponding number of containers containing ambient water, to be started. Thus, long-term empty containers can be dispensed with.

In such a regulation can be provided that all containers are kept filled with fluid or ambient water when there is no need for receiving the fluid or other fluid through the modular system.

On the other hand, however, it may be provided in constant preparation for a relief event that a certain number of containers are always kept empty unless all of the containers of the modular system are filled with the fluid.

In a preferred development of the invention, the containers have the dimensions of containers that can be easily transported. In particular, come as a container commercially available containers in question, which can be equipped in a simple way as a fluid receptacle. The containers are pre-assembled with accessories completely in the factory. They are usually designed so that they can be easily transported to the place of use. There, only the connection to the sewage system and the foundation at the bottom of the water can be done.

A container, that is to say a module of the module system, can consist of a plurality of containers, which are connected to one another for the purpose of exchanging fluid during fluid filling or exchange of ambient water when the ambient water is being filled. In particular, the containers may be connected according to the principle of communicating tubes.

In a preferred arrangement, the containers are placed on one side, e.g. along the side, arranged adjacent to each other, the intermediate walls are removed. Thus, continuous spaces are provided without intermediate partitions of large capacity for the fluid.

In particular, ISO containers can be used as containers.

The above object is further achieved according to the invention by the use of one or more containers as Fluidaufnahme- container in a body of water, the container has rigid walls and an inlet and a drain for the fluid and an inlet and outlet for the ambient water of the water.

Such a container may, as noted above, be an ISO container.

As stated previously, the use of one or more rigid-walled containers with a fluid inlet and outlet and circulation water provides an optimally simple way of providing it as a fluid containment vessel in a body of water. The container can be procured commercially easily equipped as a fluid receptacle for a body of water. The entire pre-assembly can be carried out at the production site. Since such containers are designed so that they can be transported in the easiest way with vehicles provided for this purpose and moved with dedicated cranes, they can be easily deployed on site and sunk in the bank of the water in this.

The containers can easily with inlets and outlets for the fluid and the ambient water of the water body, with pumps provided for this purpose and with others for fluid buffering appropriate technologies. Containers offer the simplest solution of all containers previously proposed for fluid caching. The advantages mentioned apply in particular to ISO containers.

The containers, which are equipped or retrofitted as fluid receptacles, after they have been transported to the place of use, are assembled into a respective module and connected to the sewage system by one or more pipes. Several such modules are arranged to the module system used as Mischwasserzwi- storage. As described above, one or more modules are kept empty or, in the case of volume delivery control, pumped empty as needed. When mixed water accumulates, it first fills this module. At the same time, further modules, which have hitherto been filled with the ambient water from the water body, are pumped empty in a fixed number or in regulation as required. Thus, the entire system can be successively filled with mixed water, while ambient water is pumped out of it into the water. If the module system is completely filled with mixed water, the system waits until the sewerage system in question is ready to start again. Thereafter, the process is reversed by the mixed water is pumped successively, while the ambient water of the water, preferably by its own pressure, flows into the modules. In this case, a part of the container remains empty. Once all of the mixed water has been pumped out of the module system, the entire system may be filled with ambient water, if timely information about a relief event and, possibly, the size of the discharge event is expected, or if a fixed number of containers are kept empty to provide a given volume , In the former case, emptying is started only when an unloading event is reported. In the latter case, regardless of the message of a discharge event, one or a certain number of empty pumped modules are available for receiving mixed water. supply.

Depending on the total weight of the modules and the maximum number of empty modules in certain cases, the plant can be kept at the bottom of the water by means of shallow or deep foundations.

In addition to counteract the buoyancy caused by the weight of the modular system, the containers can be weighted with a surcharge.

The containers may have pumping means for pumping out the fluid and the ambient water through the respective drain.

Furthermore, the containers may have a device for rinsing off deposits of the fluid. In particular, this device may have one or more Wirbelj ets. With such vortex jets, solids can be continuously suspended and / or settling deposits can be released from the bottom of the containers for cleaning.

To prevent deposits in the containers, these or several composite modules can also have a closable opening on a side wall near the bottom through which ambient water flows into the containers at a corresponding pressure and thus rinses off deposits. The inflow of the ambient water can be done for example by opening a slide.

In order to be able to rinse off deposits more easily, the bottom of the container is preferably formed inclined.

Furthermore, the containers are preferably provided with smooth inner sides. The insides may also have a dirt-repellent layer.

For maintenance of the containers, these may have an access opening at their top. The containers can also be equipped with technologies for cleaning the fluid, for example by ozone, UV light, sieving, precipitation and / or flocculation.

Advantageously, the containers on a level gauge, which registers the respective filling and thus the remaining volume for receiving the fluid or ambient water and the complete filling and displays.

The surfaces of the containers may be used to create usable foundations in the shores of the water body for, for example, platforms, structures, green areas or wastewater treatment plants.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawing show

1 is a simple module in the form of a container,

FIG. 2 shows another embodiment of the container shown in FIG. 1, FIG.

3 shows the module of FIG. 2 with foundation and ballast,

Fig. 4 shows a combination of several containers according to FIGS. 1 and 2 to a module with a larger capacity and

Fig. 5 is a five-module system, with three modules are filled with ambient water, one module is empty and the fifth module is filled with mixed water.

In Fig. 1, a fluid receptacle 1 is shown as a simple module of a modular system of such containers 1, wherein the fluid receptacle 1 is made in the dimensions of a container, so that the transport can easily take place. The container 1, together with the rest of the modular system forming containers are completely pre-assembled at the place of manufacture. After its transport to the place of use together with the other containers, only the connection to the sewage system and the foundation are made there.

The container is connected to the (not shown in the drawing) drains through a pipeline. Shown in FIG. 1 is the inlet 2 and outlet 3 for the fluid, that is to say the mixed water obtained in the sewage system, in the form of a pipe socket. The drain 3 leads into the vicinity of the container bottom 4. Furthermore, a pumping device 5 is shown in Fig. 1, with which the mixed water from the container 1 can be pumped back into the sewer.

The container 1 further has an inlet 6 and outlet for the ambient water of the surrounding it (not shown in the drawing) body of water 5. The sequence is identical to the sequence 3 for the mixed water. Through it, both the mixed water and the ümgebungswasser pumped through the pumping device 5. As the mixed water is pumped back to the sewer through the pipe 7, e.g. through a two-way valve the ambient water pumped back through the pipe 8 into the water.

The container 1 also has at its bottom 4, a vortex jet 9 for the prevention of sedimentation. In addition, a level gauge, control means for the pumping device 5 and control means for the injection and pumping of mixed water and ambient water depending on the size of the reported discharge event or a reported recovery capacity of the sewer systems may be provided.

The container 1 is equipped with smooth side walls to minimize deposits. The container bottom 4 has a flow inclined to the outlet 3 for the mixed water, so that deposits can be easily rinsed off. The container 1 may eventually be equipped with technologies for the purification of the mixed water, for example by ozone, UV light, screening, precipitation and / or flocculation.

The inner sides of the container 1 are provided with a dirt-repellent layer 10 for reducing dirt deposits. At the top of the container 1, a (not shown in the drawing) manhole for maintenance of the container 1 may be provided.

Fig. 2 shows a variant of the container 1, wherein instead of a vortex jet of the inlet 6 at the opposite end of the drain 3 for preventing and rinsing deposits ambient water flows with a corresponding pressure in the container 1. The ambient water can flow through the inlet 6 by opening a slide 11 into the container 1.

Fig. 3 shows schematically a possible foundation of the container 1 in the bottom of the water. The founding is carried out as a deep foundation with the help of piles 12.

In order to keep the container 1 against its buoyancy in the waters at the bottom of the water, a load 13 is provided on the top of the container 1.

However, the buoyancy force of the container 1 in the water is significantly reduced by a successive described by way of example successive filling and emptying of the module system from such containers with fluid, so mixed water in the example considered here use, and ambient water.

As is apparent from Fig. 4, a plurality of containers 1, which are the size of a container, combined by removing the long partitions to larger capacity spaces. The here for example four containers 1 module then has only one inlet 2 for the mixed water and an inlet 6 for the ambient water. Furthermore, a sequence 3 for the mixed water and the ambient water is provided. hen. For pumping out the mixed water or ümgebungswassers the pumping device 5 is used.

The consisting of several (here four) containers 1 in container form modules are assembled at the site and lowered in the shore area in the water.

Fig. 5 shows an arrangement of five modules in the bank region 14 of the water body 15. The modules are longitudinally attached to each other and fixed by pile foundation at the bottom of the water. In order to keep the buoyancy of the module system as low as possible and thus reduce the cost of the foundation in the water bottom, it is provided that the module system is constantly filled up to a maximum of one module with ambient water of the water and / or mixed water from the sewer system. This happens as follows.

As long as there is no need for receiving mixed water from the sewerage system and even if there is no partial filling of the module system with mixed water, at least some of the modules are filled with ambient water from the water body. In the embodiment under consideration, in this situation, the module shown on the left in FIG. 5 is empty, while the remaining four modules are filled with ambient water. When mixed water enters the module system through the sewer, it first fills the empty module. At the same time, the module adjacent to the right, which has hitherto been filled with ambient water, is pumped empty. This situation is shown in FIG.

If the first module is filled and even more mixed water flows through the sewer system, the second module is filled. Meanwhile, the surrounding water is pumped out of the third module located to the right. Thus, the entire module system can be successively filled with mixed water until at most all modules of the system are filled with mixed water and thus the absorption capacity of the module system is reached. The mixed water then remains in the module system until it passes through the sewer system can be resumed. Then, the mixed water from the modules is successively pumped back into the sewerage system by each one empty container 1 is filled with ümgebungswasser the water through the corresponding inlet. This can be done by opening the slide 9 shown in FIG.

If the sewerage system is able to hold the entire mixing water volume of the modular system, either the last module pumped empty, the module shown at the far left of Fig. 5, is filled with ambient water, if enough time remains to be expected in the event of a discharge event being reported in good time, the module is from the surrounding water to empty again, or the module is kept empty in readiness of a Mischwasserzström.

For successive filling of the modules with mixed water or ambient water, the next adjacent modules may be connected to an overflow, so that when a module is filled with mixed or ambient water and further space for receiving mixed or ambient water is needed, the water in the next adjacent module flows in.
