Abstract

The aim of the invention is to construct an industrial installation (1), for example an industrial power plant, comprising a large number of functional units with dimensions that have been proportioned in accordance with a predeterminable design parameter, using a minimum of design and planning resources. To achieve this, an inventive modular system comprises a number of modular components (2, 10, 20, 30, 40, 50, 60), each of which contains a number of functional units, which are grouped according to their function, each modular component (2, 10, 20, 30, 40, 50, 60) having standard dimensions that are independent of the design parameter.

Modular system for creating an industrial plant

The invention relates to a module system for creating an industrial system to be designed with regard to a specifiable design parameter.

Industrial plants such as manufacturing plants or industrial power plants are usually designed with a predefinable design parameter in mind. This can be, for example, a production capacity that can be specified as a design parameter, a production throughput or, in the case of an industrial power plant, a design output or nominal output. Depending on the design parameter specified in this way, functional components are usually dimensioned, which are then combined in a suitable manner to create the overall system. In the case of an industrial power plant, for example, the dimensioning of a turbine and a generator connected downstream of it takes place in such a way that the combination of these components with regard to the electrical power that can be generated reaches or exceeds the design or nominal power specified as design parameters. Further components required for the operation of the industrial power plant are then suitably combined in a further step, compatibility being generally to be ensured as a boundary condition between the individual components.

When building such industrial plants, especially industrial power plants, each project is usually redesigned by specialized specialists based on the design parameter. However, this requires a comparatively high amount of effort already in the offer stage. The development of project-specific solutions is particularly complex because various development teams specializing in different key components of the industrial plant each have to be redesigned for the respective component have to make. In order to reduce this effort, so-called "delta engineering" has so far attempted to draw on the knowledge gained from previous, similar projects and, on this basis, by incorporating the specific deviations of a new project from the requirements of previous projects To allow minimum new development effort to arise.

In order to keep the planning and development effort for such an industrial plant even lower, it is also possible to subdivide the overall industrial plant to be designed with regard to the design parameter into a number of functional groups, which add up to a complete industrial plant. Each function group can be designed with regard to a special sub-function in the overall process covered by the industrial plant. The functional units required for this subfunction can be combined in a function-specific manner into a ^• module component. With such a modularized concept, the entire system can be set up in the manner of a modular system with a particularly short installation time at the place of use.

Such a modularized structure makes planning and development work for a new project easier. However, the planning and development effort for a new industrial plant is still comparatively high.

The invention is therefore based on the object of specifying a module system of the type mentioned above with a plurality of functional units which are dimensionally matched to the design parameters and with which the design and planning effort for an industrial plant to be newly built is kept particularly low. This object is achieved according to the invention in that the functional units are combined in a function-specific manner into a number of module components, each module component being dimensioned in a standardized manner independently of the design parameter.

The invention is based on the consideration that a so-called modular or module principle should be adhered to particularly largely for a particularly low planning and design effort of a newly constructed industrial plant. It should therefore be ensured that modules are provided for the construction of the industrial system in such a way that they can be combined with one another in a particularly simple manner even in the case of a large number of application variants. The functional units are functionally combined to form module components, which can also differ from one another in terms of their dimensions or design. In such a module system, however, the effort for so-called “delta engineering” can be kept particularly low, since the requirements of “delta engineering”, that is, the transfer of knowledge for a design parameter to the design according to a design parameter that deviates therefrom, exclusively are restricted to the components that are necessarily to be adapted to these design parameters. Accordingly, an adaptation in the context of “delta engineering” is only intended for the functional units as such, whereas the module components themselves are exempt from such adaptations.

In an advantageous embodiment, the module components are standardized in terms of their outer dimensions in a function-specific manner. In other words: each module component has external dimensions, which are adapted to the corresponding sub-function within the overall process of the industrial plant, but which, on the other hand, are kept independent of the specifically specified design parameter. It is thus achieved that with regard to a grouping or In a joint installation at the place of use, the module components each have predefined external dimensions in the manner of standard modules, so that the installation and positioning of the module components relative to one another can take place in a uniform and standardized manner, regardless of the design parameter.

In order to keep the design effort for each module component particularly low, in a further advantageous embodiment the functional units combined to form a module component are positioned within the module component independently of the design parameter. "Delta engineering" is thus restricted solely to a suitable selection or specification of the individual functional units as such. In addition, however, the functional units have predefined positions within the module component assigned to them, so that no additional design effort is required to determine a particularly favorable position of the respective functional unit within the module component is required.

The functional units which are combined to form a module component are usually interconnected within the module component via a number of connecting elements in order to be able to reliably perform the intended sub-function as a whole. In order to keep the required design effort particularly low when interconnecting the functional units, in a particularly advantageous embodiment the connecting elements within the module component are spatially independent of the design parameter. In order to enable adaptation to the specified design parameters, the connecting elements themselves are expediently dimensioned as a function of the design parameters. In particular, it can be provided that in the case of pipes as connecting elements, their spatial arrangement within the respective module component is fixed independently of the design parameter, with other the pipe cross-section is varied depending on the design parameter.

In a particularly advantageous embodiment, the module system is designed for a configuration of the industrial system, if required, with particularly high safety standards. For this purpose, the module components are advantageously designed in such a way that optional redundant assembly with selected functional units is possible without any other structural changes to the module components. In particular, a number of the functional units within the module component provided for them are expediently designed to be redundant.

The module system is particularly suitable for the construction of an industrial power plant, a design power or a nominal power being advantageously used as the design parameter.

The advantages achieved with the invention consist in particular in that the overall design and development effort for the construction of the industrial plant is kept particularly low by consistently dividing into functional units dimensioned as a function of the design parameter and modular components dimensioned independently of the design parameter. By maintaining standardized dimensions or dimensions for the module components as such irrespective of the design parameter, the required "delta engineering" is limited to the functional units as such when knowledge of similar industrial systems is available. A basic concept can therefore be based on only a limited number of standardized components for an industrial plant, in particular a power plant, which in principle already covers a large range of conceivable design parameters. Specification for the design of the industrial plant with a design parameter selected from this area then only requires the corresponding Appropriate adapted design of the individual functional units, without the need for a revision of the actual basic concept for the overall system.

An embodiment of the invention is explained in more detail with reference to a drawing. In it show:

FIG. 1 shows a top view of a modular industrial plant,

Figure 2 shows a module component in side view, and

Figure 3 shows the module component of Figure 2 in supervision.

Identical parts are provided with the same reference symbols in all the figures.

An industrial power plant is provided as the industrial plant 1 according to FIG. 1. The industrial power plant is designed to comply with a design parameter, a design power or nominal power of 5 MW being specified as the design parameter in the exemplary embodiment. The industrial plant 1 is of modular construction, the process covered by the industrial plant 1 as a whole, namely the conversion of energy stored in a fuel into electricity, being divided into a number of sub-functions.

For the actual generation of electricity, the industrial plant 1, which is designed as an industrial power plant, comprises a first module component 2. The first module component 2 comprises, as functional units, a turbo set 4 with a steam turbine and a generator 8 coupled to it via a transmission. These functional units are part of the module component 2 functional subsystem that can be transported together as a whole. In the exemplary embodiment, the turbo set 4 is set up on a concrete foundation comprising a base plate, columns and a table top. Alternatively, it can also be designed in a block construction, whereby it stands on a ground-level foundation block made of concrete and steel. The type of installation provided in the exemplary embodiment on the table top supported by columns usually causes higher costs for turbo sets than the installation on a ground-level foundation block, but on the other hand offers great advantages when routing pipelines, accommodating a condenser under the turbine and during maintenance.

In order to supply the turboset 4 with working medium, the industrial plant 1 has a steam generator block as a further module component 10. A steam generator 12 is arranged in the module component 10 and is connected to the turboset 4 via a water-steam circuit on the working medium side. In the steam generator 12 there is an evaporation of the feed water which is fed to the turbo set 4 after its subsequent overheating in the steam generator 12. The steam generator 12 is connected on the flue gas side to a chimney 14 arranged outside the module component 10.

To supply the steam generator 12 with fuel, the industrial system 1 comprises a further module component 20. In the exemplary embodiment, the fuel supply is a heating oil supply. For this purpose, a number of day tanks 22 are accommodated in the module component 20, which are matched to the power of the steam generator 12.

To complete the water-steam cycle, a module component 30 is further specified, in which components of a feed water system are combined. The module component 30 thus includes, in addition to a feed water tank 32, a high pressure preheater, a feed water degassing, a number of feed pumps, a low pressure preheater, a number of metering systems for inoculating the feed water and a sampling device. The feed water provided by the feed water supply serves to supply the steam generator 12 with working medium. On the input side is the The water supply is connected to a condenser assigned to the turbo set 4 and accommodated in the first module component 2, so that a closed water-steam cycle is created. In addition, functional units such as a heating oil preheating station 34 and a heating oil pump station 36 are also arranged in the module component 30 and are to be assigned to the fuel supply.

For water treatment, the industrial plant 1 further comprises a module component 40, in which a multiplicity of functional units, which are not specifically described, are arranged. The module component 40 includes, among other things, pressure booster pumps and multi-layer filters for raw water, a concrete water pool as a clean water pool, a filter rewind pump, a cation exchanger, a CO trickle, further pressure boosting pumps, an anion exchanger, a mixed bed filter, a regeneration station, a neutralization pool with circulation pump , and a reservoir for NaOH and for HCL arranged. The storage containers are designed for a fortnightly requirement and made of glass fiber reinforced plastic. Associated pipes, brackets and fittings are also made of plastics. In the module component 40, a special space for a water laboratory 42 and for a control 44 of the water treatment are also provided.

A further module component 50 is provided for recooling the condenser arranged below the turbo set 4. In this a number of cooling towers with suction fans are combined in a row. In the exemplary embodiment, the cooling towers are set up in two cells 52. Each of the cells 52 has a load-bearing steel frame, to which only plastic parts for external planking, as an air inlet grille, as trickle fittings, for water distribution and as drip catchers are attached. A fan deck and a defuser are also made of plastic. The cells 52 are set up over a concrete basin provides that it also serves as a fire extinguishing basin and is therefore oversized. A pump house 54 is also assigned to the module component 50, in which two cooling water pumps 56 are accommodated. These feed the condenser arranged below the turbo set 4 with cooling water, which is conducted in reflux through the cooling towers arranged in the cells 52.

The electricity generated in the generator 8 is fed to a further module component 60, in which part of the electricity feeds a self-service transformer designed as a dry transformer. The major part of the electricity generated by the generator 8, on the other hand, is fed to a machine transformer, also not shown, which is also arranged in the module component 60, and is released from there into a consumer network, also not shown.

The module system thus comprises module components 2, 10, 20, 30, 40, 50, 60, in each of which a number of function units is combined in a function-specific manner. The dimensioning of the functional units, such as, for example, the turbo set 4 and the generator 8, are adapted to the nominal power of 5 MW specified in the exemplary embodiment as a design parameter. In contrast, however, the module components 2, 10, 20, 30, 40, 50, 60 are more dependent on their function, but more independent of the nominal power specified as a design parameter

Dimensioned standardized way. In particular, the module components 2, 10, 20, 30, 40, 50, 60 are kept in their external dimensions independently of the nominal power specified as a design parameter. A uniform, standardized set-up of the module components 2, 10, 20, 30, 40, 50, 60 according to the arrangement shown in the exemplary embodiment in FIG. 1 is therefore also possible for an industrial plant 1 with a different design performance, in particular also a particularly space-saving so-called Wall-to-wall installation of some module components 2, 10, 20, 30, 40, 50, 60 can be retained even with varying design parameters. For further clarification, the module component 30 is shown enlarged in FIG. 2 in side view and in FIG. 3 in top view. The module component 30 includes, in addition to the components for the fuel supply not shown in FIGS. 2, 3, the feed water tank 32, which is connected via a first suction line 70 to a feed water pump 72 and via a second suction line 74 to a redundant feed water pump 76 provided for safety reasons is. The feed water pumps 72, 76 are connected on the output side to a pressure line 78.

The module component 30 has an outer frame 80 formed from a number of support elements. As indicated in FIGS. 2 and 3 by the double arrows, the outer scaffold 80 is standardized in its height 82, in its length 84 and in its width 86 and thus in all of its outer dimensions and is implemented independently of the design performance. In other words, even when designing an industrial system with a design performance that differs from industrial system 1, the use of a module component 30 with unchanged external dimensions, i.e. unchanged height 82, unchanged length 84 and unchanged width 86, is provided for the feed water area. Likewise, the positioning of the feed water tank 32 within the module component 30 is provided regardless of the design performance. The positioning of the feed water tank 32 is essentially given by the height 88 of a support plate 90 for the feed water tank 32 indicated by the double arrow. The arrangement of this support plate 90 remains unchanged during the transition from one design performance to another design performance.

Furthermore, the spatial arrangement of the suction lines 70, 74 provided as connecting elements and the pressure line 78 within the module component 30 is retained regardless of the design parameter. In contrast to this, both the dimensioning of the feed water tank 32 provided as a functional unit and the feed water pumps 72, 76 provided as further functional units as well as the dimensioning of the suction lines 70, 74 provided as connecting elements and the

Pressure line 78 selected depending on the design or nominal power provided as a design parameter. In the exemplary embodiment according to FIGS. 2 and 3, this is indicated by the multiple line: as the multiple line symbolizes, a comparatively small feed water container 32 is provided for the case of a comparatively small feed water requirement, whereas a comparatively larger one is provided for the case of a comparatively large feed water requirement Feed water tank 32 is to be set up.
