Description
20141 ~3 Field of the Invention The invention refers to an apparatus for treating gases, in particular flue gases, said apparatus comprising a hollow casing which extends mainly vertically, said casing holding various built-in components, in particular floors, column separators or gas washers.
Prior Art Known apparatuses comprise a casing which is dimensioned to cater for the whole amount of gases to be treated, said casing including built-in components arranged in such a manner that they extend across the whole clear opening of said casing.
The above leads to the disadvantage that mostly very large cross-sections are necessary. This causes problems in dimensioning and constructing the components to be built in.
Furthermore, large cross-sections, which can be found in known apparatuses of the above mentioned kind, cause the flow through the built-in components to vary across the cross-section, whereupon their effectiveness is reduced accordingly.These difficulties cause planning of such apparatuses to be very expensive and time-consuming and, furthermore, require extensive model tests. This consequently leads to long periods of construction which constitute a considerable disadvantage in a time when regulations on environmental protection are made more and more stringent.
SummarY of the Invention It is the object of the invention to avoid these disadvantages and to propose an invention of the above mentioned kind which, on the one hand, enables a mostly consistent flow across the whole cross-section of the built-in components and, on the other hand, requires only relatively simple supporting structures for the built-in components.
According to the invention this is achieved in that the casing is subdivided by at least two crossing partitioning walls, whereby fixing devices are attached both to said partitioning walls and the interior walls of said casing, said fixing devices being arranged for placing on to it floors, column separators, demisters or spraying devices and that said casing comprises connections or openings for feed pipes and 2 2~141 ~3 that guiding plates are arranged for separating the gas flow and directing it towards the subdivisions of the cross-sections of the casing.
Thereby the above results in correspondingly small cross-sections and simple fixing devices for the components to be built in, whereby said components, with regard to their statics, may be dimensioned considerably smaller than those which would be necessary ior the same gas flow in prior solutions. Furthermore, this measure leads to a more even distribution of the gas flow to be treated, said distribution occurring across the whole cross-section of the casing.
A further feature of the invention may comprise the exterior wall of the casing having fixing devices, said fixing devices being intended for mounting auxiliary units such as pumps or accumulators.
These measures enable the arrangement of an accumulator behind each built-in component operating in a wet manner, such as gas washers, column separators and such-like, and to place said accumulator only slightly lower versus the respective built-in components. Consequently less pumping power is required within circulations, as the lifting heights for pumps are very small.
It is a further object of the invention to propose an arrangement with apparatuses in accordance with the invention, said arrangement being easily adjustable to the gas flow to be treated and not requiring extensive planning therefor.
In accordance with the invention this is achieved in that prefabricated casings in various predefined sizes are erected at a distance from each other and that said casings comprise built-in components according to the respective requirements, whereby a separate, if necessary~controllable, supply of the gas to be treated is arranged for each of the parallelly fed casings.
This measure allows modular prefabrication of both casings and fixing devices for various components to be built in, whereby it would suffice, for the various plants, to place the number of casings which are required for treating the developing gases next to each other.
There is an additional advantage in that in the case of part-load operation even the apparatus for treating the developing gas flow may be adjusted to the respective amount 3 2~4~
of developing gases, so that the part of the apparatus for treating the gas flow which remains in operation can be operated at a capacity of around 100 percent, e.g. within a range of 80 to 120 percent, thereby causing optimal conditions even in the case of part-load operation. If this is applied to the whole apparatus one can start out from the fact that even in the case of minute part-loads, efficiency is very high.
It may be further intended that each casing consists of several components, said components being connected to each other and being arranged in a stack-like manner, which simplifies production of prefabricated modules. Furthermore, this enables adjustment to the respective requirements, in particular to the number of stages of treatment which are required for the gas flow.
It is a further object of the invention to propose an arrangement comprising apparatuses according to the invention for treating larger amounts of gases, said apparatuses being easily adju6table to the amount of gases to be treated.
In accordance with the invention this is achieved in that prefabricated casings in various predefined sizes are erected at a distance from each other and that said casings comprise built-in components according to the respective requirements, whereby a separate, if necessary controllable, supply of the gas to be treated is arranged for each of the parallelly fed casings.
Depending on the amount of gases to be treated, this measure allows the arrangement of a number of apparatuses according to the invention, said apparatuses being designed for relatively small amounts of gases, thereby causing low planning requirements. By placing the apparatuses at a di~tance, mutual influence, in particular thermal coupling, is avoided. Furthermore, arrangements constructed in such a manner may also effectively be operated at part-load operation, as in this case a pertinent number of apparatuses can be turned off or excluded from utilization.
Brief De~criPtion of the drawinas Based on the drawing the details of the drawing are outlined as follows:
Fig. 1 shows a diagrammatic top view of an arrangement with apparatuses in accordance with the invention.

Brief De~criPtion of the drawinas Based on the drawing the details of the drawing are outlined as follows:
Fig. 1 shows a diagrammatic top view of an arrangement with apparatuses in accordance with the invention.
4 2~14~3 Fig. 2 shows a vertical section through an arrangement with apparatuses in accordance with the invention.
Detailed Description of Preferred Embodvment As is diagrammatically outlined in fig. 1, each of the apparatuses consists of casing 1 with a more or less square profile. Said casing is subdivided by two crossing partitioning walls 2. Fixing devices 3 are attached to these, as well as to the interior walls of casing 1, whereby said fixing devices 3 are intended for accepting or supporting various components to be built in, such as floors, demisters, column separators, spraying devices and such-like.
The arrangement in accordance with fig. 1 shows several such apparatuses 5 which are connected to accumulator 8 via corresponding feed pipes 6, said feed pipes preferably comprising independently controllable ventilators 7.
As can be seen from fig. 1, the subdivision of the clear opening of casing 1 results in relatively small sizes for each component to be built in, so that said components are subjected to very low mechanical stresses during operation and thus need only be dimensioned very weakly.
The subdivision of the cross-section also causes the gas flow to be treated to pass through said components more evenly.
Fig. 2 diagrammatically shows a vertical section through an arrangement with inventive apparatuses 5.
Therein casings 1 of apparatuses 5 consist of several parts 9 to 12, said parts being arranged in a stack-like manner and connected to each other and having on their facing ends flanges 13.
The lowermost part 9 of casing 1, said part also comprising feed opening 14 for the gases to be treated, in partlcular flue gases, comprises guide plates 15, said plates ensuring even distribution of the inflowing gases to the four divisions across the clear opening of casing 1, said divisions being brought about by partitioning walls 2.
Parts 10, 11 and 12 of casing 1 comprise, as was already outlined based on fig. 1, fixing devices on partitioning walls 2 and the interior walls of casing 1.
Various components to be built in, such as floors 16, demisters 17, spraying devices 18, column separators 19, distribution devices 20 for e.g. injecting oxygen, ozone, or a 2~1~183 mixture of such gases for a denitration device for removing nitrogen oxides from flue gases, or dust collectors 21 are either supported by or attached to said fixing devices.
Furthermore, casing 1 comprises openings 22 for various pipes, said openings allowing compact guiding of the pipes through said casing.
Apparatuses 5 are arranged at a distance from each other, but are connected via stages 23. Accumulators 24 are attached to said stages, whereby said accumulators are connected on the one side with collecting pipes of column separators 19 and on the suction side with pumps 2~, said pumps being intended for upholding circulations, in particular for lime milk for desulphurization or for ammonia for discharging nitrates from a denitration device.
Both casings 1 and the components to be built in may be prefabricated in various predefined sizes for various plants. Depending on the amount of gas to be treated, a pertinent number of apparatuses 5 according to the invention may be erected and may parallely be fed with the gas to be treated.
Cross-section sizes of 2m x 2m, 2.5m x 2.5m and 3m x 3m have proved to be preferable for casings 1. Each subdivision results in a relatively small area of cross-section. In the case of such small areas of cross-section, it is relatively simple to determine the reactions which will take place and the flow of the gases to be treated through the built-in components. This makes model tests unnecessary which otherwise have to be performed for large areas of cross-sections of e.g. lOm x lOm, whereby the results of said tests are not always satisfactory.
Due to the inventive measures it is very easy to erect plants for treating large amounts of gas with the lowest possible planning efforts, because one only has to erect the pertinent number of subdivided casings. Thus it is also po8sible to adjust the apparatus for treating the gas flow to the amount of gas to be treated, as the supply of gas to the respective casings, said casings comprising the respective 20~4~3 built-in components, may either be interrupted or opened. It may further be intended to arrange respective control devices in separate feed pipes, said pipes leading to each partial cross-section of each casing, thus causing the partial cross-sections of the casings fed by the gas flow to practically operate at their normal rating.
Detailed Description of Preferred Embodvment As is diagrammatically outlined in fig. 1, each of the apparatuses consists of casing 1 with a more or less square profile. Said casing is subdivided by two crossing partitioning walls 2. Fixing devices 3 are attached to these, as well as to the interior walls of casing 1, whereby said fixing devices 3 are intended for accepting or supporting various components to be built in, such as floors, demisters, column separators, spraying devices and such-like.
The arrangement in accordance with fig. 1 shows several such apparatuses 5 which are connected to accumulator 8 via corresponding feed pipes 6, said feed pipes preferably comprising independently controllable ventilators 7.
As can be seen from fig. 1, the subdivision of the clear opening of casing 1 results in relatively small sizes for each component to be built in, so that said components are subjected to very low mechanical stresses during operation and thus need only be dimensioned very weakly.
The subdivision of the cross-section also causes the gas flow to be treated to pass through said components more evenly.
Fig. 2 diagrammatically shows a vertical section through an arrangement with inventive apparatuses 5.
Therein casings 1 of apparatuses 5 consist of several parts 9 to 12, said parts being arranged in a stack-like manner and connected to each other and having on their facing ends flanges 13.
The lowermost part 9 of casing 1, said part also comprising feed opening 14 for the gases to be treated, in partlcular flue gases, comprises guide plates 15, said plates ensuring even distribution of the inflowing gases to the four divisions across the clear opening of casing 1, said divisions being brought about by partitioning walls 2.
Parts 10, 11 and 12 of casing 1 comprise, as was already outlined based on fig. 1, fixing devices on partitioning walls 2 and the interior walls of casing 1.
Various components to be built in, such as floors 16, demisters 17, spraying devices 18, column separators 19, distribution devices 20 for e.g. injecting oxygen, ozone, or a 2~1~183 mixture of such gases for a denitration device for removing nitrogen oxides from flue gases, or dust collectors 21 are either supported by or attached to said fixing devices.
Furthermore, casing 1 comprises openings 22 for various pipes, said openings allowing compact guiding of the pipes through said casing.
Apparatuses 5 are arranged at a distance from each other, but are connected via stages 23. Accumulators 24 are attached to said stages, whereby said accumulators are connected on the one side with collecting pipes of column separators 19 and on the suction side with pumps 2~, said pumps being intended for upholding circulations, in particular for lime milk for desulphurization or for ammonia for discharging nitrates from a denitration device.
Both casings 1 and the components to be built in may be prefabricated in various predefined sizes for various plants. Depending on the amount of gas to be treated, a pertinent number of apparatuses 5 according to the invention may be erected and may parallely be fed with the gas to be treated.
Cross-section sizes of 2m x 2m, 2.5m x 2.5m and 3m x 3m have proved to be preferable for casings 1. Each subdivision results in a relatively small area of cross-section. In the case of such small areas of cross-section, it is relatively simple to determine the reactions which will take place and the flow of the gases to be treated through the built-in components. This makes model tests unnecessary which otherwise have to be performed for large areas of cross-sections of e.g. lOm x lOm, whereby the results of said tests are not always satisfactory.
Due to the inventive measures it is very easy to erect plants for treating large amounts of gas with the lowest possible planning efforts, because one only has to erect the pertinent number of subdivided casings. Thus it is also po8sible to adjust the apparatus for treating the gas flow to the amount of gas to be treated, as the supply of gas to the respective casings, said casings comprising the respective 20~4~3 built-in components, may either be interrupted or opened. It may further be intended to arrange respective control devices in separate feed pipes, said pipes leading to each partial cross-section of each casing, thus causing the partial cross-sections of the casings fed by the gas flow to practically operate at their normal rating.
