Description

Device for gassing liquids

with at least one linear gasifier

description

The invention relates to a device for gassing liquids with at least one linear gasifier according to the preamble of claim 1.

It is generally known that gases, which also include gas mixtures, are supplied to a liquid in two different variants. A distinction is made between fumigation into the liquid above or at the liquid surface by diffusion and fumigation into the liquid below the liquid surface by pressure, whereby different operational concepts such as continuous or intermittent entry or entry of the gas are implemented with and without circulation of the liquid .

Entry systems for fumigation below the liquid surface are, for example, rubber membrane or silicone membrane aerators or ceramic aerators in plate, tube or plate construction. These aerators are installed on rigid piping systems or combined with hose systems, which as such or in connection with an aerator are typically attached to the bottom of a basin or reactor.

A disadvantage of known compressed air ventilation systems is the high outlay for assembly with fixed and rigid connecting elements or the welding of ventilation lines made of plastic and, as a result, a high outlay for disassembly in the case of repairs, cleaning or replacement and replacement. Contamination and clogging problems are partially solved by the fact that manufacturers recommend in the operating instructions to apply maximum air and / or gas to the systems for a certain period of time in order to remedy the impairments caused by the soiling and clogging mentioned. In addition, organic acids are introduced into the aerator systems sporadically or at fixed intervals in order to dissolve organic particles which adhere to the openings and / or to the surfaces of the aerators. The invention is based on the object of providing a new concept for a gassing device which enables simple handling.

This object is achieved by a device with the features of claim 1. Embodiments of the invention are specified in the dependent claims.

Thereafter, the solution according to the invention is characterized in that a tubular linear gasifier, which has at least one outlet opening in its tube wall, which is provided for the entry of a gas into the liquid, at least one of its ends via a plug and / or screw connection with another Component of the device is connected. The connection between the linear gasifier and the other component is gas-tight.

The solution according to the invention is based on the idea of providing the linear gasifier - and in other embodiments of the invention also other components of the device - with a plug and / or screw connection, so that the entire device with the linear gasers inserted therein can be removed quickly and easily from one Basins or bodies of water and also a quick assembly and disassembly of the device or only the linear gasifier itself is possible. As a result, the assembly times are reduced and, in particular, a high flexibility of the gassing device is achieved, since the structure can easily be modified to meet changed requirements such as a change in the amount of gas to be introduced or the position in the water body. Another advantage is that maintenance of the gassing device is made easier, since instead of the entire ventilation system or parts thereof, components can be easily cleaned, repaired or replaced, each with no or minimal interruption to operation.

The solution according to the invention allows for all known boundary conditions such as natural irregular or artificial uniform geometry of each individual body of water or an adaptation to installation locations with several geodetic plateaus in each case within a compressed air supply system and, at the same time, needs-based control of the gas requirement in the respective zones and locations of the respective water body at the respective time a reliable fumigation. According to one embodiment of the invention, the linear gasifier is characterized by dimensional stability in the radial direction and elasticity in the axial direction. Due to the radial dimensional stability, this can be part of the plug connection without a special device or special tool and can be introduced, for example, into a seal.

The outlet opening is preferably arranged in a region of the linear gasifier such that a bubble emerging from this outlet opening does not coalesce with another bubble emerging from an adjacent outlet opening on the way from the outlet opening to the surface of the liquid.

Embodiments of the invention provide that the device for the gassing of liquids has a plurality of linear gasifiers, each of which is provided with a plug and / or screw connection. It can further be provided that all linear gasers are provided with a plug connection at at least one end, or that all linear gasers are provided with a combined plug and screw connection at at least one end, or that all linear gasers are provided with a screw connection at at least one end . It can also be provided that individual or all of the linear gasifiers are provided at their ends or at branching points with different of the connections mentioned (plug connection, combined plug and screw connection, screw connection).

One embodiment of the invention provides that the connection between the linear gasifier and the further component takes place via a plug connection, which is realized in that the end of the linear gasifier is inserted into a seal which is arranged in the further component, the linear gasifier being non-positive is held in the seal. For this purpose, provision is made, for example, for the seal to have an elastic wall and a central opening into which the end of the linear gasifier is inserted, the elastic wall and the central opening being designed such that the end of the linear gasifier inserted into the central opening is non-positively connected the seal is held. The linear gasifier widens the elastic wall, so that the linear gasifier can be pressed in, so that there is a high gas tightness and stability of the connection. The seal is, for example, a rubber seal. A further embodiment of the invention provides that the connection between the linear gasifier and the further component takes place via a combined plug and screw connection, which is realized in that the end of the linear gasifier is inserted into a rubber seal which is in one end of a connecting piece is arranged, and the other end of the connector is threaded and screwed to the other component. According to this embodiment variant, an intermediate piece, the connecting piece, is thus provided, in one end of which the linear gasifier is inserted via a rubber seal and the other end of which has a thread, the connecting piece with the threaded end being screwable to another component.

It is pointed out that the plug-in and / or screw connection can have further configurations, for example can also be designed as a pure screw connection or as a connection with a bayonet lock, a connection via a bayonet lock being a plug-in connection in the sense of the present invention.

The connection variants mentioned can be implemented for a line which carries the gas (for example a connecting line or distribution lines in the sense explained below), but also for intermediate components and branching components which serve to connect the linear gasifier to a further linear gasifier. In this way, these connection variants can be used to connect the linear gasifier directly to a gas source.

The further component to which the linear gasifier is connected is, for example, a supply line for the gas which, in addition to supplying the gas from a compressor, also has the task of positioning the linear gasifier at the location in the liquid provided for the gas entry can.

One embodiment of the invention provides that the linear gasifier is connected directly to a compressed gas source via a plug and / or screw connection. This represents the simplest embodiment of the device, since no further lines such as connecting lines and / or distribution lines are required. Such configurations of the invention can be used, for example, in koi and fish ponds. For example, linear gasifiers and / or connecting elements made of stainless steel are used, which also act as ballast against buoyancy. One embodiment provides that at least one linear gasifier has at least one first longitudinal section which has no outlet openings and at least one second longitudinal section in which it has at least one outlet opening. In the first longitudinal section, in which the linear gasifier has no outlet opening, it takes over the function of a connecting line. This section therefore only serves to guide the gassing medium to the second section with outlet openings. The first longitudinal section is arranged, for example, in the ground or in a basin or body of water between the compressed air source and the linear gasifier. It can also be provided that the linear gasifier has a plurality of longitudinal sections in which it does not form any outlet openings, so that, for example, at least one of these sections is provided for fastening the entire tube or, for example, two non-perforated longitudinal sections at the beginning and end of the linear gasifier the function of the connection take over another component of the device.

A further embodiment of the invention provides that at least one of the linear gasifiers is connected at one end to a further component of the device, and at its other end is provided with a closure, for example a stopper or a cap, so that the gas escapes exclusively via the outlet openings are made in the tube wall of the linear gasifier. This variant can be combined, for example, with the configuration in which the linear gasifier is connected directly to a compressed gas source.

A further embodiment of the invention provides that the further component to which the linear gasifier is connected via a plug and / or screw connection is a connecting line which is provided to supply the gas to the at least one linear gasifier. A connection line is a non-perforated line which is connected to the gas source directly or via at least one further line. It can be provided here to connect a plurality of linear gassers to one another via a connecting line or to supply gas to the linear gassers with one another.

A linear gasifier is connected to a connection line, for example, via a connection element in the form of an elbow, an angle, a T or Y piece or directly via a seal or a screw connection, so that assembly and disassembly can be carried out in a simple manner. A seal can also do this to be non-positively and positionally stable with an adhesive and / or pasty solidifying substance with a connecting line and with a distribution line.

A further embodiment of the invention provides that the further component with which the linear gasifier is connected via a plug and / or screw connection is a distributor line. The distribution line contains the gassing medium from a gas pressure source or another line connected to it. The distribution line and the linear gasifier are screwed together and / or plugged together. It can be provided that, in the presence of flow in the liquid to be gassed, flexible linear gassers are connected, as a result of which the linear gassers follow the direction of flow and deposits are washed away again and again by the flow. The general rule is that the linear fumigators can be rigid or flexible in relation to their left extension, a flexible design means that the linear fumigator can be adjusted in the longitudinal direction to the course of the flow during installation and / or by the flow.

Furthermore, it can be provided that the distribution lines have a plurality of perforations in the tube wall along their extension, via which the linear gas feeders are connected to the distribution line, the linear gas feeders, for example, in each case by means of a seal which is introduced into a perforation and is pressed into the respective perforation, is pluggably connected to the distribution line.

According to a further embodiment, the device comprises, as further components, at least one connection line and at least one distributor line, the connection line being connected to the gas pressure source, the connection line and the distributor line being connected to one another, and the further component with which the linear gasifier is connected via a plug and / or screw connection is connected, which is or one of the distribution lines. This configuration represents a larger network of device components for gassing, in which one or more distribution lines are connected to one or more connection lines.

According to one embodiment, the connection between the connection lines and the distribution lines is also made in that these connection lines and distribution lines are screwed together and / or plugged together, which is further increased by simple installation and the flexibility of the system. One embodiment provides that a plurality of distribution lines each have a plurality of perforations in the tube wall along their extension, via which a plurality of linear gasifiers are connected to the respective distribution line. It can be provided that the linear gasifiers are each connected to a distributor line by means of a seal introduced into a perforation or are connected to a distributor line using a connecting element screwed to a perforation.

One embodiment of the invention provides that two distributor lines arranged parallel to one another are provided, each of which has a plurality of perforations in the tube wall along its extent, the two distributor lines being connected to a connecting line at at least one of their ends. A plurality of linear gasifiers are provided, which are connected at both ends to the two distribution lines via the perforations.

Several distributor lines and at least one connection line or several connection lines and at least one distributor line form one or more fields into which the linear gasifiers connected to the distributor or connection line enter the gas.

The linking of at least one field connecting and distribution lines and at least one linear gasifier is also referred to as a module. It can be provided that at least one linear gasifier is connected at the two ends to another distribution line. Several modules can be connected via a connecting cable. A high degree of branching ensures that the gas is distributed over a large area and that the gas input is highly efficient.

In the case of a pronounced branching on a connection and / or distribution line and thus a pronounced distribution of the volume flow of the gas introduced, it is preferably provided that in order to maintain the flow pressure in the distribution lines and the linear gasifiers, the distribution line has an inner diameter which is the same or larger than that of the connected linear gasifier and the connection line have the same or larger inner diameter than the connected distribution lines.

A further embodiment of the invention provides that the device has at least one openable and closable closure built into a line, which is controlled via a solenoid valve, for example. The closure is attached, for example, to the connection point of a linear gasifier with a distribution line. With this configuration, the gas can generally be metered into the liquid as needed or distributed in the liquid body. If there is a high need for a gas to be entered, the entry can be made from all connected linear gasifiers. If the gas to be introduced has a lower requirement, only a part of the closures on the linear gasifiers can be controlled or acted on in such a way that a gas is only introduced into the distribution line to which exactly the part of the linear gasifier from which the proportionate gas flow is connected should be entered into the liquid.

In addition, for example, the closure at each end of a linear gasifier, which is connected at both ends to a different distributor line, enables the gas to be input as required by controlling the inflow direction and the inflow pressure. Furthermore, for entry control, it can be provided that at least one openable and closable and / or non-openable closure divides a distributor line or connecting line into segments, as a result of which the gas uptake of the individual segments and thereby also the gas discharge from the connected linear gasifiers can be controlled.

According to a further embodiment of the invention, it is provided that linear gassers are connected in series with one another with the aid of connecting and stabilizing elements that prevent the linear gassers from rotating, or to connect or control them, a connection again being made via a screw and / or plug connection. Connection and stabilization elements fulfill the task of connecting at least two linear gasifiers with one another, so that they form a longer line which is simultaneously fixed by the at least one connection and stabilization element and which introduces the gas into the liquid. It can be provided here that at least one connection and stabilizing element has a branch, so that the linear gasifiers form a branch with one another. In addition, controllable, openable and closable closures can be provided on at least one connection and stabilization element, which enables control of the gas input into a segment of the line of the linear gasifiers connected in series.

A further embodiment of the invention provides that at least one linear gasifier or at least one combination of linear gasifiers connected in series on both Is connected at the same connection line or distribution line or to the same gas pressure source and thereby forms a ring line.

The connection line, distribution line and linear gasifier can consist of all materials that can be permanently connected to the connection and distribution lines. Embodiments of the invention provide that a connecting line, a distribution line and a linear gasifier are made from noble steels of the group V2A and V4A or from suitable plastics, primarily PVC, PA, PP, PE or PET. The choice depends on the requirements of the place of use, for example heat and radiation resistance, and the requirement for elasticity. Seals can be made from all suitable materials such as rubber, silicone, EPDM, NBR and / or Teflon. A connecting line, a distribution line and a linear gasifier are manufactured in cross-section as a circular profile, rectangle, square, triangle, ellipse, square or other geometric figure.

A further embodiment of the invention provides that the device comprises at least two gas pressure sources in order to avoid or minimize pressure losses within the lines with pronounced branching and / or large distances.

A connecting line or a distribution line or a linear gasifier or a combination of these lines can also be secured against buoyancy by means of a ballast weight, the weight preferably being arranged within the pipe wall or line or within the linear gasifier. Such a weight is formed, for example, by rods or a rope.

Furthermore, a linear gasifier can be operated by a clamping device, e.g. a rope, a cord or a rod or comparable suitable elements are secured against partial or complete bending along its longitudinal axis, wherein the tensioning device can be arranged in the linear gasifier or externally connected to the linear gasifier and the distribution line. The gassing device can thus be secured against deformation, for example in the event of pressure surges or incorrect operation, or by larger amounts of deposits, by means of external or internal bracing of the linear gassers.

The two aforementioned measures of a ballast weight and a tensioning device are particularly useful when the linear gasifier is formed from a plastic and is accordingly flexible and comparatively light. In particular, without a tensioning device, the problem can arise that a flexible linear gasifier deposits on the adjacent distribution line due to the pressure from the liquid flow, which can limit the entry efficiency by overlaying perforations of all built-in linear gasifiers.

In general, the invention provides a device, the individual components of which can be screwed into modules and / or plugged together or screwed or plugged together. A distinction is made between connection lines, distribution lines and linear gasifiers. A connection line is a non-perforated line which is connected to the gas source directly or via at least one further line. A linear gasifier is a tubular line which has at least one outlet opening in its tube wall, which is suitable for introducing a gas into a surrounding liquid. A distribution line is a perforated line to which the linear gas feeders are connected and which is arranged between the connection line and the linear gas feeder or is connected directly to a pressure source and from which no gas is introduced into the surrounding liquid.

Different design variants of the invention provide only linear gasifiers, combinations of linear gasers and connecting lines, combinations of linear gasifying devices and distribution lines and combinations of linear gasifying devices, connecting lines and distribution lines.

After final assembly, the modules can be lowered and put into operation without being attached to the bottom of a pool and can be braced or weighed down or fixed against downforce and also against abrasion. A module can consist of one field and more than one field. A field in a module is a unit with a connection line into which the gas is introduced from an external gas supply system, such as a compressed air system, and from which the gas can flow into a distribution line, to the rigid and / or flexible linear gasifier and / or either individually or can be connected several times and also combined with one another at an angle of 1 ° to 179 ° and from which the gas can get into the liquid. In a field, a connection line can also take over the function of a distribution line and a distribution line can also take over the function of a connection line.

The modules can be inserted into the liquid from the edge of the pool and lifted out of the liquid from the edge of the pool. A module can be composed of at least one field with at least one connection line and at least one distributor line and at least one linear gasifier connected to the distributor line.

FIG. 1 shows a distributor line 21 and a plurality of linear gasifiers 10, 11, 12, 13, 14 connected to it, which have different shapes in the exemplary embodiment shown. However, this is only to be understood as an example. It can be provided that, in a specific implementation, all linear gasifiers emanating from a distribution line 21 have the same shape.

The gas to be introduced into a liquid can emerge from the openings from openings with diameters of, for example, 1 gm to 100 gm in a wall of a linear gasifier 10, 11, 12, 13, 14, the openings being either single-row and also offset from one another along the Longitudinal axis of the linear gasifier can be arranged (compare openings 1A) or can be arranged in a row parallel to the longitudinal axis of the linear gasifier (compare openings 1) or with more than one row parallel to the longitudinal axis of the linear gasifier (compare openings 2) or offset in more than one row (compare openings 3) can be arranged in a linear gasifier. The openings can also be random, i.e. without a defined geometric pattern, be formed in a linear gasifier.

The linear gassers 10, 11, 12, 13 and 14 can be screwed to the distributor line 21 or connected to seals 5, 5A introduced into the distributor line, each with a plug-in connection, the linear fumigator being designed to be radially stable (ie its diameter also occurs when it occurs) a radial force) and is inserted into the respective seal 5, 5A. A pull-out protection is provided by a frictional connection between the seal and the distribution lines. A linear gasifier 10, 1 1, 12, 13 and / or 14 can be connected to one side of a distribution line 21 or to a distribution line 21 on both sides of the linear gas supply units 10, 1 1, 12, 13 and 14 as well as on both sides opposite side of the distributor line, the further linear gasifiers 10A, 11A, 12A, 13A and 14A can be connected, the linear gasers 10A, 11A, 12A. 13A and 14A can be connected to and connected to the distribution line 21 in the same way as the linear gasifiers 10, 11, 12, 13 and 14. The linear gasifiers can be connected directly to the distribution line or they can be connected to the distribution line via a connecting element 6, 6A.

In addition, other linear gasers of the variants shown can be connected in the same way to further rows of distributor lines, it also being possible for a linear gasifier to be coupled to different distributor lines at its two ends.

Figure 2 shows a section of Figure 1, wherein the linear gasifiers 10, 1 1 and 12 are connected at one end to a distribution line 21 and at the other end to a further distribution line 21 A, in the case of a non-parallel position and position of the Distribution line 21 A to the distribution line 21 for a tension-resistant and equally tight connection to the distribution line 21 A, a separate seal 7 may be required.

Linear gasifiers, which are connected to the distribution line 21 at only one end, can be provided with a closure 4 or 4A at their non-connected end. Linear gasifiers, which are connected at one end to the distribution line 21 A and at the other end to the distribution line 21, can be arranged at one of their ends at a closure 8 in the distribution line 21 and at the closure 8A in the distribution line 21 A, the closures can be controlled and opened and closed. In this way, entry control is given by the possibility of introducing a gas from only one of the two distribution lines 21 or 21 A or from both distribution lines.

If linear gassers are connected at both ends to a distribution line 21 and 21 A or are connected to a distribution line 21 and 21 A, one end of a linear gasifier in a distribution line can be provided with a closure 8 or 8A, which makes it possible to alternate from one of the distribution lines, a gas is introduced into only the part of the linear gasifier whose connection to the respective Distribution line is open. Through this one-sided opening or this one-sided closure 8 and 8A of a linear gasifier, the entry of a gas into a liquid can be controlled in such a way that it is possible to enter a gas as required. Likewise, in this mode of operation, the gas can be distributed further into the liquid in the reaction space and can be metered or distributed in this manner as required. If there is a high demand for a gas to be entered, the entry can be made from all connected linear gasifiers; if the gas to be entered is lower, only a part of the linear gas feeders can be controlled or acted on in such a way that a gas can only be introduced into the distribution line to which exactly the part of the linear gasifier from which the proportionate gas flow is to be introduced into the liquid is connected.

The closure 4 or 4A and the closure 8 or 8A can be attached and / or introduced by screwing or welding or gluing or clogging or by a combination of the aforementioned types of closure.

FIGS. 3 to 7 show top views and further views of various exemplary embodiments of a device for the gassing of liquids. The following applies to these figures:

Linear gassers 10, 12 etc. according to FIGS. 1 and 2 are connected to distribution lines (e.g. distribution lines 21, 21 A, 21 B, 21 C of FIG. 3), the linear gassers only being shown schematically and not on each distribution line. In principle, linear gasers of any shape can be connected to the distribution lines.

With a single manifold 21 (Fig. 3) or a series of manifolds 61, 61 A, 61 B, 66 (Figs. 4 and 5), a gas from an external pressure system or from a compressor can be connected to one in the manifold Connection line to the connection 27, 27A (FIG. 3, 5) provided in the line or to a linear connection 26 (FIG. 3-7), 26A (FIG. 6) of the connection line 22 (FIG. 3) or connected to more than one distribution line from a series of distribution lines, can be introduced into linear gasifiers. A linear connection is characterized in that the gas flows directly from the pressure generation source into the connection or into the distribution line, as from an extension of a connecting or supply line. The gas can come from a connection line 22, 22B, 22D, (all Fig. 3) 60 (Fig. 4), 66 (Fig. 5), 70 (Fig. 6), 74, 74A (Fig. 7), the length of which from 10 mm to 1 000 000 mm and their diameter and opening width from 1 mm to 1 000 mm can be in a distribution line 21, 21 A, 21 B, 21 C (all Fig. 3), 61, 61 A, 61 B (all Fig. 4), 65 (Fig. 5), 71, 71 A, 71 B, 71 C, 71 D, 71 E, 71 F, 71 G (all Fig. 6), 75, 75A, 75 B. (all Fig. 7), the length of which can be from 10 mm to 1 000 000 mm and the diameter and the opening width of which can be from 1 mm to 1 000 mm, and can be from a distribution line into one or more than one linear gasifier, the length of which between 1 mm and 100,000 mm and their diameter and opening width from 1 mm to 100 mm and which can be made / manufactured over the entire length or in sections round, rectangular, square, elliptical, polygonal or in any other geometric shape , got into the liquid gene.

From FIG. 3, the schematic representation of a top view of an exemplary embodiment of a module, in which the exemplary embodiment from FIGS. 1 and 2 is integrated, it can be seen that through a connecting line 22 a gas from an external pressure system or from a compressor at one in the connecting line connection 27, 27A provided for this purpose in the line or to a linear connection 26, which is connected to the connection line, is introduced into a connection line itself or into a module. The gas can be introduced both at a connection 27, 27A in the line or at a linear connection 26 connected to the connection line simultaneously or separately into the fields 28 and 29 and further into the fields 30 and 31 and 32. The fields 30, 31 and 32 can have their own connection 27, 27A or their own linear connection 26. The geometric dimensions of each individual field 28, 29, 30, 31, 32 can differ from one another, as a result of which the connecting lines 22, 22 B and / or 22 D and the distribution lines 21, 21 A, 21 B and / or 21 C can have different lengths and can have different diameters. Fields can be open on one side, like fields 31 and 32. Distribution lines from open fields 31 and 32 can be closed with a closure 33 and / or 34. The closure can be screwed on 34 from the outside or inserted 33 from the inside. The closure can be self-sealing and / or closed with a thread-sealing seal or with an inserted seal or any other suitable seal.

Connection line 22, distribution line 21 and linear gasifier 10, 1 1, 12, 13 and / or 14 can be combined to form a field in a module in such a way that connecting elements such as bends and / or angles 23, T-pieces 24 and / or branches 25 connect the connecting lines to the distribution lines in a gas-tight manner. The connecting elements 23, 24 and / or 25 can be plug connections,

Bolted connections and as such can also be combined in one module in one module. Modules can be connected to one another via a common distribution line 21 C.

Linear gasifiers can be connected to the opposite distribution lines over the width of a field 28 or to the opposite connection lines over the length of a field 29. Linear gasifiers can be installed as a single line with one end connected to a distribution line 36 or with both ends connected to a distribution line 35, for example, far into a body of water such as a lake.

As can be seen from FIG. 4, a field in a module can consist of a connecting line 60 to which a connecting element 62 or more connecting elements 62 and to which a T-piece 24 or more T-pieces 24 can be connected which can / can be a gas in one and / or in more than one distribution line 61, 61 A and / or 61 B, to which linear gasifiers can be connected on one or both sides, put together or screwed or put together and screwed. The connecting line 60 and the distribution lines 61, 61 A and 61 B can be closed at one end with a closure 33 or a cap 34. Instead of a T-piece, a Y-piece and a cross-piece or an arc or an angle, the last two with a radius of 1 ° to 90 °, can be used.

Figures 5 and 7 each show in a sectional view, in the upper representation in a plan view and in the lower representation in a side view each an embodiment in which the distribution line 65, 75 and connection line 66, 74 run parallel and are arranged one above the other, whereby they are touch (Fig. 5) or are arranged at a distance from each other (Fig. 7).

FIG. 5 illustrates that at least one connection line 66 and at least one distributor line 65 can be connected and operated with one another in such a way that both lines are connected directly with one another and the gas flows directly from the connection line 66 into the distributor line 65, the connection line 66 preferably above the distribution line 65 is arranged. The gas flows out of you linear connection 26 or from a side connection 27, 27A into the connecting line.

FIG. 7 shows an embodiment in which at least one connecting line 74 and at least one distributor line 75, 75A and 75B are connected to one another in such a way that the two lines are operated at a distance from one another in a network and that a gas from the connecting line 74 passes over Connecting elements 76 flows into the distribution lines 75, 75A and 75B, the connecting line 74 preferably being arranged above the distribution line 75.

In the arrangements of FIGS. 5 and 7, a cover 67 (FIGS. 5, 7) can be attached to the side of the line assembly in order to avoid deposits between the lines, or a filling compound 68 (FIGS. 5, 7) or a filling compound 68 (FIGS. 5, 7) can be introduced under the cover in combination with the cover 67 (FIGS. 5, 7) or instead of the cover. The parallel longitudinal axes of the connecting line and the distribution line can be arranged around a central axis at an angle of rotation of 0 ° to 180 ° to one another, which at 0 ° and 180 ° means a parallel position in the horizontal and at 90 ° a parallel position in the vertical corresponds.

FIG. 6 shows a top view and a sectional view of a further exemplary embodiment of a device for the gassing of liquids, in which at least one connecting line and at least one distributor line connected to one another in such a way form a field in a module that the gas from the linear connections 26 and 26A in the connecting line 70 and flows via the connections 72 into the distribution lines 71, 71 B, 71 C, 71 E, 71 F and 71 G and that the distribution lines 71 A and 71 D perform the function of the connecting line and the distribution line equally. The module can be installed and operated at an angle> 0 ° to the horizontal.

The distribution lines 71, 71 C and 71 F, like the distribution lines 71 B, 71 E and 71 G, and also the connecting lines 71 A and 71 D, can be installed on a common geodetic height and also at different geodetic heights and as connected Unit operated.

FIG. 8 shows a distribution line 85 which has a closure which can be openable and closable and can be controlled or not opened, and the distribution line 85 in Segments 85A and 85B divided. It can be connected on one or both sides to a linear connection 26. In this way it can be achieved that either all linear gasifiers connected to this distribution line by simultaneously entering a gas on both sides of both ends of the distribution line or, if only one end of the distribution line is input, only the portion of the linear gasifier that either only to segment 85A or is only connected to segment 85 B, to be charged for the entry of the gas into the liquid. It is also possible that a connection 27, 27A is introduced into each of the two segments 85A and 85 B of the distribution line and, in the case of a connection 27, 27A, the ends of the distribution line or a segment of the distribution line can be closed with a cap 34.

A distribution line 85 (FIG. 8) can be operated independently without insertion into a module / field or connection to a connection line.

Elastic linear gasifiers 11, 12 (cf. FIGS. 1 and 2) are preferably connected to a single distributor line which is not connected to a field. This combination of a single distributor line 85, also with the segments 85A and 85B, with elastic linear gasifiers primarily in the design 1 1, 12 (see FIGS. 1 and 2) and 1 1 A, 12A (see FIGS. 1 and 2) can be used primarily where substances can accumulate on the linear gasifiers 1 1, 12 and 1 1 A, 12A (see FIGS. 1 and 2). Due to the elasticity of the linear gassers 1 1, 12 and 1 1 A, 12A (cf. FIGS. 1 and 2), linear gassers can follow the direction of flow, as a result of which deposits can be washed away with the flow. For this purpose, the linear gasifiers 10A, 10, 1 1, 1 1 A, 12 and 12A (cf. FIGS. 1 and 2) at an angle of 90 ° or, depending on the direction of flow of the liquid, at an angle between 1 ° and 179 ° the distribution line 85 are connected.

FIG. 9 schematically shows a top view of an embodiment in which linear gasifiers 95 are connected via a connecting and stabilizing element 92 and are therefore connected in series. FIGS. 10 and 11 show schematically in plan view (FIG. 10) or from the front (FIG. 11) the connection principle of a linear gasifier to two connection and stabilizing elements 92. A connecting and stabilizing element 92 is characterized in that linear gasers 90 (Fig. 10, Fig. 1 1), 95 (Fig. 9) can be operated as a composite for the entry of a gas into a liquid. For the introduction of the gas into the linear gasifier 90 (Fig. 10, Fig. 1 1), 95 (Fig. 9) or for the entry of the gas into the connection and stabilization element 92 (Fig. 9, Fig. 10, Fig. 1), the connection and stabilizing element can be equipped with a connection made of a thread or a sleeve 91 (Fig. 1), 91A (Fig. 9). Furthermore, to stabilize the position of a linear gasifier and the alignment of the bores in a linear gasifier, the connection and stabilizing element can be designed such that the position and alignment of a linear gasifier remain stable in position during operation. The transition from the linear gasifier 90 (FIG. 10) to the connection and stabilizing element 92 (FIG. 10) can be provided with seals 93 into which the linear gasers are inserted. A connecting and stabilizing element 92 (FIG. 9, FIG. 10, FIG. 11) can be provided with a closure or plug 96 (FIG. 11) for openings for which a gas does not flow through.

According to FIGS. 9-1 1, a row of linear gassers 95 can also be characterized by a branch 94, which can be connected at an angle between 1 ° and 179 ° to a connecting and stabilizing element, in order to guide the row of linear gassers 95 to be able to adapt the geometry of a basin or reactor or to local conditions such as in a lake or any other body of water. Two or more linear gassers 95 can be connected in series in this combination, it being possible to provide a connection and stabilizing element 92 at the ends of a linear gasser or a plurality of linear gassers and between two linear gassers, which can connect at least two linear gassers connected in series. A series of at least two linear gasifier 95 connected to connection and connection elements can be provided with a stopper 33 (see FIG. 3) or with a cap 34 (see FIG. 3-7) or a closed connection and stabilization element 92A (see FIG. Fig. 1 1) be completed blind. The final blind connection and stabilizing element 92A (FIG. 11) can be retrofitted at any time in such a way that an extension to a row with at least one further linear gasifier can be possible from this element.

The row of linear gassers (FIG. 9) can be divided into segments by a closure element 86 (FIG. 9), which is either used permanently or can be opened and closed, for example, with a solenoid valve or a controlled flap. In this case, each connection and stabilization element 92 (FIG. 9) can form the element via which the gas is introduced into the respective segment or module. A gas can be introduced into any other connection and stabilization element via a connection 91 and fed into the linear gasifier. If a row is divided into more than one segment, at least one connection and stabilization element 92 (FIG. 9) can be used in each segment in order to introduce the gas into the respective segment via this connection and stabilization element. The segmentation of a line of linear gasifiers connected in series can result in needs-based entry control options. An end element 97 and 97A (FIG. 9) of a row can form an end to the row.

FIG. 12 shows a field which, in this embodiment, also represents a module which is formed from two connecting lines 100, 100A and two distribution lines 101, 101A. The gas supply from a gas pressure source or from at least one external connection line connected to a gas pressure source takes place in this exemplary embodiment via connections 27 integrated into the connection lines 100, 100A, to which, depending on the arrangement angle to the gas pressure source or further connection line, a corner connection can be connected. Connection line 100, 100A and distribution line 101, 101A can be plugged together and / or screwed together via a corner connection 23 such as angles or arches or via a T-connection 24, which makes handling during assembly / disassembly easier. The linear gassers 102 are each inserted with their two ends into a perforation in the opposing distribution lines. This takes place via a seal 5, 5A, which is pressed into the respective perforation. The difference in inner diameter between the distribution lines 101, 101 A and the linear gasifiers 102 prevents one

Gas pressure difference between the highly branched distribution lines 101, 101 A and the linear gasifiers 102.

FIG. 13 shows a sectional illustration of an exemplary embodiment of a flexible linear gasifier 103 consisting of a plastic, into which a tensioning device 81 and a ballast weight 80 are integrated. The tensioning device 81 is formed, for example, by a cord or a rod or a rope, as a result of which the linear gasifier 103 is tensioned in the longitudinal direction and is thereby secured against partial or complete bending. For example, the clamping device used has a load capacity between 1 kg and 20 kg. For example, it has a diameter between 0.2 mm and 5.0 mm. Alternatively, the tensioning device 81 could be attached to the outside of the linear gasifier 103. The ballast weight 80 is integrated in the linear gasifier 103 and secures it against buoyancy. The ballast weight 80 is formed, for example, by rods or ropes.

FIG. 14 again explained different types of connection between a linear gasifier and a further component of the device.

FIG. 14 shows a connecting line 21 to which linear gassers are connected, which are linear gassers 10, 10A, 1 1, 1 1 A, 12, 12A, 13, 13A, 14, 14A, 35, 36, 90 , 95, 102, 103 of the previous figures. For the sake of simplicity, the linear gasifier is described below with reference number 10.

A linear gasifier 10 is each connected to the connecting line 21 using a seal, which can be one of the seals 5, 5A, 6, 6A, 7 of the preceding figures. For the sake of simplicity, the seal is described below with reference number 5.

As shown at the bottom left, the connecting line 21 comprises one

Connection bore 104 into which a seal 5 is pressed. The seal 5 comprises an elastic wall 51 and a central opening or bore 52 into which the end of the linear gasifier 10 is inserted. The material of the elastic wall 51 and the size of the central opening 52 are designed such that the connection between the linear gasifier 10 and the seal 5 is non-positive. At the same time, it is gas-tight. The elastic wall 51 consists, for example, of rubber, silicone, EPDM, NBR or Teflon.

As shown in the bottom center, the connecting line 21 has a

Connection bore 105, which forms an internal thread 109. The connection of a linear gasifier 10 to the connecting line 21 takes place with the interposition of a connecting piece 106. This has at one end 108 an opening into which a seal 5 is inserted, which in turn has an elastic wall and a central opening. One end of the linear gasifier 10 is inserted non-positively into the central opening. The other end 107 of the connecting piece 106 has an external thread, via which the connecting piece 106 is screwed into the connection configuration 105. The illustration at the bottom right shows an embodiment variant in which both ends 107 of the connecting piece 106 are provided with an external thread.

FIG. 14 also shows a coupling element 1 1 1, which serves to connect two linear gasifiers 10. The coupling element 1 1 1 has two ends, in each of which a seal 5 is inserted. As described, the seal 5 can each have an elastic wall and a central opening. On the outside, the coupling element 1 1 1 can be provided with one or more external threads (not shown) if it is to be screwed into a surrounding structure.

FIG. 14 also shows a branch element 110, which has three openings, into each of which a seal 5 of the type described is inserted. The branch does not have to be at right angles, as shown, but can be implemented at any angle between 1 ° and 179 °.

FIG. 14 also shows a cross coupling element 1 12, which is used for the gas-tight connection of four linear gasifiers 10. The linear gassers 10 can be closed at one end by a stopper 14 or a melt or clamp closure 115. In the four openings of the cross-coupling element 1 12, a seal 5 of the type described is in turn inserted.

FIG. 14 also shows an end piece 1 16 of a linear gasifier 10 in the form of a screw cap 1 13, which is placed on one end of the end piece 1 16. In the other end of the end piece 1 16, a seal 5 of the type described is inserted.

The connection of a linear gasifier 10 to a further component of the gassing device thus takes place in exemplary embodiments via a plug connection using a seal 105 or via a combined plug and screw connection using a connecting piece 106. Further design variants see, for example, a connection via a bayonet lock or via a pure screw connection.

In all of the exemplary embodiments, the connecting elements, such as, for example, the connecting elements 106, 1 10, 1 1 1, 1 12, 1 13, can be made of metal, and they additionally provide the function of a ballast against buoyancy of the gassing device. The design of the invention is not limited to the exemplary embodiments described above, which are to be understood only as examples. For example, provision can also be made for the gas to be fed into a module or into a simple combination of connecting and / or distribution lines and linear gasifiers or of linear gasers connected in series via more than one gas pressure source. In addition, it can be provided, for example, that differently shaped linear aerators are used in comparison to the linear aerators shown. Furthermore, it is pointed out that the features of the individual described exemplary embodiments of the invention can be combined with one another in various combinations. If areas are defined, they include all values within these areas as well as all sub-areas that fall within one area.
