Description
Technical Field
The present invention relates to a separation system of a ship exhaust gas desulfurization apparatus. The separation system should on the one hand ensure that the ship equipped with the separation system complies with the requirements of new emission regulations at sea. On the other hand, the separation system should overcome the known problems of stack rain (strong drainage of liquid droplets from wet stacks). Furthermore, the separating system should minimize as far as possible the contamination of the components following the droplet separator (in the direction of the exhaust gas flow) taking into account the operating experience of the last decades.
Exhaust gases from diesel-fired marine engines are desulfurized for discharge from the stack, mainly according to the wet scrubbing method. For this purpose, the sulfur-containing waste gas is conducted through a vessel which is located in front of the chimney in the direction of the exhaust gas flow. In this vessel, the sulfur-containing off-gas is sprayed with seawater (suspension solution), and the SO in the off-gas2Incorporated into the sprayed droplets of the suspension solution. In particular, the larger spray droplets are collected by gravity in a trough arranged below the inlet into waste water which can be cleaned in further method steps, while the smaller spray droplets are carried along by the gas flow.
The aim of the invention is to reduce the amount of liquid droplets carried.
Since new effective or planned emission regulations also provide for a significant reduction in the solid content of the exhaust gases, in other words for a reduction in fine dust, a further task of the invention is to improve the separation efficiency.
Background
Modern separation systems for flue gas desulfurization are nowadays installed in the upper region of the vessel (also referred to as "scrubber head") to which the flue gas channel or chimney is connected in the direction of the flue gas flow. These separation systems are typically loaded with exhaust gas flowing vertically upwards. This arrangement has been shown to be the preferred configuration for cost reasons and for operational reasons.
The separation system separates the liquid droplets and, if appropriate, the dry solid constituents from the exhaust gas flow, in which the solid constituents are deflected several times in the separation system by means of flow resistance. Here, the droplets and the dried solids are subjected to centrifugal forces. They cannot follow the exhaust gas in their path, but rather impinge on the flow resistance which causes the exhaust gas flow to deflect, and are also referred to as "impingement bodies". The liquid droplets are thereby separated onto the impact body and are thus removed from the exhaust gas flow. Due to gravity, the liquid droplets and, if appropriate, the solid components fall down into the container and thus again into the gas stream or into the tank.
In the prior art, the separation system usually comprises a set of plate-shaped and curved deflection bodies. These generally rigidly suspended deflectors are generally configured so as to form a channel through which the exhaust gas flows. The aim of such an arrangement is, on the one hand, to cause a strong deflection of the exhaust gas and, on the other hand, to minimize the "blockage" of the exhaust gas path caused by flow resistance.
The impact body or deflector is often also referred to as "plate", which corresponds to a "plate separator" or also just a "plate". The usual plates of different manufacturers differ in terms of geometry, plate distance, deflection and form of construction ("top", "flat" or "horizontal" inflow).
The experience of conventional power stations is that when the exhaust gases are introduced into the stack after the exhaust gas desulfurization plant (REA), so-called stack rain occurs. This chimney rain consists of large droplets with a significant solids content (ash) and is acidic (lower acid content). On the one hand, this is due to the condensation of droplets from the saturated exhaust gas, which are cooled on the way through the flue and which condense on the chimney walls. Where they are disengaged from the exhaust gas stream and discharged from the stack.
To avoid this, it is known in power stations to use reheating devices. The reheating device heats the exhaust gas and thereby evaporates residual liquid droplets located in the exhaust gas and avoids condensation of saturated gases.
On the other hand, chimney rain also forms due to penetrations in the separation system. "breakthrough" means that the droplets leave the separation system downstream, either because the separation system is inoperative (fouling, incorrect configuration or excessively high exhaust gas velocity), or because a breakthrough of washing droplets occurs and the separation system is breached when washing the plates.
In the case of diesel-fired marine engines, the droplets of stack rain are acidic on the one hand because of the presence of sulfuric acid in them, and on the other hand have a high solids content. The sulfuric acid being derived from combustion in diesel enginesAnd (4) a burning process. Burning sulfur-containing diesel, and thus SO in exhaust gas2And SO3The content of (a) is relatively high. The liquid is dilute sulfuric acid and is correspondingly highly aggressive and corrosive. Since the solids accumulated during the washing pass into the liquid and are then largely discharged, a small portion of the solids is also entrained. These droplets then fly from the chimney and into the surroundings, thus leading to visible contamination on the one hand on the ship's walls and ship's surface. On the other hand, the droplets are acidic and aggressive, so that they decompose and corrode the color of the ship and then also the steel of the ship. Both effects are disadvantageous for the ship. Fouling plays a very negative and disturbing role especially on ships with passenger traffic. The decomposition and corrosion effects of dilute sulphuric acid on ships are worse.
Thus, acidic stack rain is disadvantageous and dangerous for the ship.
In tests it has been shown that the intensity of the chimney rain depends to a large extent on the washing cycle of the plates, to be precise, in particular on the washing of the last plate in the direction of the exhaust gas flow. It was determined that turning off the scrubbing system would result in a reduction of previously violent stack rain to a barely noticeable degree.
The determination is also consistent with the measurement of the penetration behind the panel. It has been found that during washing, the last plate in the direction of the exhaust gas flow penetrates up to 100 times the amount of liquid compared to a run without washing. In particular, it was also found that the size of the droplets increased significantly during washing. Particularly large droplets are entrained.
Thus, the effect on stack rain can be explained by the cleaning of the liquid volume and the size of the droplets. The small droplets or droplets (formed by condensation in the chimney) that penetrate the separation system in normal operation (without washing) are not noticeable as chimney rain, as they typically evaporate before reaching the bottom. While the large droplets produced by the washing plates or condensation on the chimney are large enough to reach the bottom. They rain down on the faces located below or behind the chimney, cause corrosion there due to the acid content, and cause contamination due to the bound solids.
Further, at the time of washing, the liquid droplets are conspicuous due to the amount thereof, and thus are perceived. Some droplets are ignored and not detected. However, a large number of droplets are noticeable.
Analysis of operating conditions
No connection between the process of washing the plates and the occurrence of chimney rain has been found for a long time. The occurrence of chimney rain is attributed to "poor" separation and is thus counteracted. In fact, "poor" separation is often part of the cause of chimney rain. Because droplet separation systems are partially poorly constructed or operate disadvantageously such that they only partially function and cause significant emissions.
One important reason for poor separation performance is the frequent contamination of the plates. This pollution is caused in particular by the poor combustion of diesel in the machine. The oil-containing constituents are not burned off and are carried along with the exhaust gas as oil-containing soot or oil droplets. They can then settle on the slab face and oile the slab face.
However, oiled slabs also function only very limitedly. The oil prevents a film of water from building up on the plate surface. However, this film of water is very important because it absorbs and binds the droplets located thereon. If, on the other hand, the droplets to be separated hit the oiled surface, the droplets burst and are thrown back into the exhaust gas stream instead of being separated in a water film or on the surface of a plate. A so-called secondary spray is produced. The droplets that have just been separated are therefore thrown back into the exhaust gas and continue to fly.
Contamination with oil therefore results in the respective plate no longer functioning correctly. The droplets are dispersed but not separated.
An important aspect is also that the locations for installing REA on many boats are only very limited. Everything is crowded on the ship, all space is reserved for goods or passengers, and the necessary functions are performed on a minimal site.
Disclosure of Invention
Task description
The object of the invention is to provide a separation system which uses as little liquid droplets as possible to impinge on the surface to cause separation. Another object of the invention is to provide a separation system in which, on the other hand, the sheets can also be regularly pulled and cleaned during operation. Furthermore, the configuration of the separation system should preferably be such that only minimal site is consumed, and the amount of stack rain is reduced and minimized to the extent unavoidable as much as possible.
The effect of the separator (impact body or plate), which is based on the impact of the droplets, under given environmental conditions also rapidly collects oil-containing constituents on the surface, which then prevent the establishment of a water film which absorbs the flying droplets. Thereby, the separation function is significantly impaired. The basic principle of an impinging droplet separator (as already mentioned) is that a water film is formed on the impingement surface, which ensures that the droplets are not atomized and continue to fly as a small spray upon impact, but the liquid volume of the droplets is absorbed by the water film and coalesces, as far as possible without secondary spraying. The oiled separator cannot form this water film and therefore this water film cannot function. Therefore, an alternative solution has to be found which no longer requires a water film. If the impinging droplets are ejected, this must be done in a space that is preferably depressurized or even pressureless, so that the secondary droplets do not get back into the gas flow again.
The impact bodies or plates should preferably be simple and ideally able to be pulled even during operation, so that they can be replaced and/or cleaned. By this cleaning, oiling can be reduced and preferably also kept to a minimum, for example. Thus, the adverse effects of oiling on separation can also be reduced and ideally minimized.
The replacement of the plates should preferably be possible during operation, so that downtime of the diesel drive can be avoided. Cleaning of the slab may then be performed off-line. The separation system is preferably designed such that the replacement can be carried out without danger to personnel during operation.
It is also an object of the invention to keep REA as small as possible. In this case, "small" means that the height of the entire apparatus is minimized. The structural height of the ship is limited and the chimney cannot protrude from the ship at any height. The structural height necessary for the separation system should therefore be kept as small as possible, preferably minimized.
Finally, the problem of chimney rain should be minimized. As already explained, the generation of droplets formed from dilute sulfuric acid, which can lead to stack rain, is a result of the installation of REA. Chimney rain basically includes the following three causes:
1. failure of the sheet
When the plates are not working properly, more and more liquid will be carried into the chimney and discharged. Thus, poor or oiled sheets are a source of chimney rain.
2. Washing of sheets
The plates must be washed periodically in order to remove fine ash or other solids which, on the one hand, clog the separation system over time and, on the other hand, form deposits on the plates which increasingly deteriorate the separation. However, said washing leads to a short-term discharge of large amounts of liquid in the form of chimney rain, with respect to side effects.
3. Coagulum formation
It is known that the clean gas generated after REA is a saturated gas with a high temperature, e.g. 50-65 ℃. In contrast to power stations, condensation formation occurs on the chimney walls even in the case of very short ship chimneys, since the chimney walls are usually 20 ℃ to 50 ℃ cooler than the exhaust gases. If a sufficient amount of condensate is formed, the condensate breaks away from the clean air and is discharged from the stack in the form of stack rain.
These three production types lead to stack rain containing sulfuric acid, which is correspondingly corrosive. The separation system according to the invention should preferably reduce all three types of production, minimizing it as much as possible.
Solution according to the invention
The above task is at least partially solved by a separation system according to the present invention. Since the separation system according to the invention has at least one plate extending oblong in a longitudinal direction, the longitudinal direction of which is oriented transverse or oblique to the flow direction of the exhaust gases, the plate comprises a chamber with an opening extending in the longitudinal direction, wherein the opening is arranged on the side of the plate facing the flow direction, at least a part of the droplets entrained by the gas flow and spray droplets being directed directly into the chamber. In the chamber, these droplets impact the chamber walls, however this does not (unlike the plates known in the prior art) lead to the formation of secondary sprays that may be entrained by the gas flow, since there is no gas flow flowing within the chamber. In other words, due to the design of the plate according to the invention, the impact is removed from the gas path to prevent the formation and transport of the secondary spray away.
In order to further improve the separation performance with the aim of avoiding or at least reducing stack rain, a preferred embodiment of the separation system has one or more modules, wherein each module comprises at least one, preferably a plurality of plates.
In the sense of a separation performance which is as high as possible, it is then particularly preferred if one or more modules are designed and arranged in such a way that they each define an inflow surface facing the flow direction. In other words, the gas flow is preferably directed towards the inflow surface.
Particularly preferred is a further development of the separation system according to the invention in which one or more modules are arranged such that the inflow surface extends transversely or obliquely to the flow direction.
In a very particularly preferred embodiment of the separation system according to the invention, the at least one plate is not installed in the vessel of REA through which the flue gases flow into the flue gas channel or chimney before leaving, but in the chimney, in contrast to the prior art. On the one hand, the structural height of the container is thereby significantly reduced, for example by 1000 to 2000mm, which is desirable for reducing the space requirement for REA, as far as possible. The installation in the chimney also results in the possibility of replacing the plates during operation. Because it cannot be completely avoided when the slab is replaced: leakage and exhaust gas outflow may occur. This is a considerable problem for personnel, especially when work has to be performed in the closed space where the container is located. However, due to the displacement into the chimney, the area that must be worked to replace the plates is displaced into the open area and said work is free to take place, usually under the action of the wind. By "wind action" is meant that the possibly discharged exhaust air is immediately carried away by the apparent wind acting on the ship (vector addition of the real wind and the travelling wind) and is therefore not dangerous or at least significantly less dangerous for the personnel. Since the plates can thus be replaced more frequently, the remaining problems of oiling and contamination are reduced. The slab can be removed and replaced with a (new and/or clean) spare slab at short intervals. The removed plate may then be cleaned, for example mechanically and/or chemically, with a cleaning agent. Due to this "off-line cleaning", the following advantages are achieved:
a) eliminating regular washing during operation reduces or eliminates one of the main sources of stack rain.
b) Furthermore, the separation function of the plate is significantly improved, since the negative effects in oiling are significantly reduced.
It is furthermore very preferred that in the separation system according to the invention the at least one plate is arranged in the vicinity of the exhaust opening of the chimney. Thereby solving the problem of condensate drainage. The condensate formed in the wet stack is brought together with the flue gases to a separator and separated there before the flue gases leave the stack.
Furthermore, the cross-section of the chimney in the vicinity of the outlet can be designed to be significantly larger than the cross-section of the chimney. Therefore, the velocity of the exhaust gas is reduced, and a smaller pressure loss is generated in the separator, and the separation performance is improved.
Surprisingly, it has been shown that: the sheet is particularly effective in reducing or even avoiding chimney rain, the sheet comprising:
a) a profile of a profile shape having regions which are angled in an alternating manner with preferably flat corners, and
b) at least one first and one second elongated profile, each having a central region and two edge regions which are connected to opposite edges of the central region and which end in an outer edge, the edge regions preferably being angled in accordance with the profile, wherein at least one first and one second elongated profile are each fastened to a respective region of the profile with their central regions offset in such a way that the edge regions of the elongated profiles are spaced apart from the preferably parallel-running edge regions of the profile and the outer edge of at least one of the edge regions of the first elongated profile is spaced apart from the outer edge of the edge region of the second elongated profile, so that a chamber is formed between the region of the profile and the two edge regions, and the opening is configured between the two outer edges of the edge region.
The special function of the chamber separator is that the liquid droplets do not strike against the resistance in the exhaust gas flow, but rather fly into the chamber and there strike the plate in the space. This results in the secondary droplets produced by the impact no longer being thrown back into the exhaust gas flow, but rather remain in the chamber and are separated there. There is no entrained gas flow that may cause continued entrainment of secondary droplets.
The negative function of oiling out is also largely eliminated. The oiling results in the inability to form a film of water on the surface that can absorb the impinging droplets. Thereby resulting in a significant increase in the separation of the secondary droplets. In the chamber, this is of no consequence, since there is indeed no flow of gas for absorption. The secondary droplets are either entrained with the subsequent droplets or they fall with gravity but are not generally returned to the gas stream.
In particular, it is preferred that at least two elongated profiles are fastened to such a plate on both sides of the profile in the shape of a surface.
The separation system can be further improved and the cleaning cycle can be extended by attaching a rolling separator upstream in the head of the REA vessel. The rolling separator has the following functions: on the one hand, the amount of liquid droplets in the exhaust gas is reduced and on the other hand the oil-containing components are captured and bound before they reach the actual separator.

Detailed Description
The separation system according to the prior art illustrated in fig. 1 comprises a container 7 through which the exhaust gas flow 9 is conducted in the flow direction R (that is to say from below upwards). For this purpose, the container 7 has a lateral inlet E. Below the lateral inlet E, the container 7 comprises a tank T for collecting the liquid. At the deepest point of the groove T, an outlet U is provided, through which the collected liquid can be drained off and, if necessary, can be fed to a further use or cleaning device. In the container 7, the exhaust gas flows through a spraying device 5, by means of which a liquid is delivered in the exhaust gas in the form of a spray for mixing with SO2Or SO3Bind and wash out solids. Form absorbed SO2Or SO3And droplets of solid components. They are washed out by means of a droplet separator arranged after the spraying device in the flow direction of the exhaust gas. They fall down in the container 7 and accumulate in the tank T, mostly due to gravity. However, a small part is wastedThe gases are carried along into a chimney S connected upwards to the container 7 and exit at least partially through its chimney opening 10. In order to be able to measure, for example, the moisture content, the pollutant content, etc. in the chimney, a test port 8 is provided, which enables the introduction or connection of a corresponding measuring device or measuring probe.
Droplet separators are known from the prior art, which consist of a plurality of laterally arranged layers of a separator plate, which consists, for example (as schematically shown in fig. 2), of curved layers of flat material. The multi-layered sheets can be combined by means of side walls, not shown in the drawing, into separate groups and with adjacent separate groups into a roof-shaped or V-shaped module or also into a flat module.
It has been shown that when using such plates for cleaning exhaust gases from marine diesel, undesirable chimney rain occurs because the droplets cannot be separated on the oiled surface but are thrown back into the gas stream as secondary sprays. In order to reduce the occurrence of chimney rain, the separation system according to the invention comprises a panel 1 comprising at least one chamber 2 having an opening 2a extending in the longitudinal direction L of the panel. An embodiment of such a plate is shown in fig. 3. The plate comprises a profile 14 in the form of a surface having areas 15 angled in an alternating manner with preferably flat corners. At least one first and one second elongated profile 16, 17 each have a central region 18 and two edge regions 19, 19 ' which are connected to opposite edges of the central region and which end in outer edges 20, 20 ', respectively, and which are angled in accordance with the profile, each of the at least one first and second elongated profiles being fastened with their central regions 18 offset to a respective region 15 of the profile 14 in such a way that the edge regions 19, 19 ' of the elongated profiles are spaced apart from the parallel-running region 15 of the profile 14 by a distance D. At least the outer edge 20 'of one of the edge regions 19 of the first elongate profile 16 has a distance a from the outer distance 20 of the edge region 19 of the second elongate profile 17, so that the chamber 2 is formed between the region 15 of the profile 14 and the two edge regions 19', 19, and the opening 2a is formed between the two outer edges 20 ', 20 of the edge regions 19', 19. Two long profiles 16, 17 are fastened on both sides of the profile 14. It has been shown that a separator with plates of such a configuration significantly reduces the formation of chimney rain. This can be interpreted as: at least a part of the droplets do not bounce on the outer surface and form a secondary spray, but reach into the chamber 2 and the secondary spray, which may form upon bouncing against the walls of the chamber, does not reach into the exhaust gas flow 9.
As shown in fig. 4, a plurality of plates 1 can be combined into one module by an arrangement that is preferably parallel to each other and further preferably equidistant, preferably in the following manner: the module can be arranged in the separation system in such a way that it forms an inflow surface F which extends transversely or obliquely to the flow direction R.
In the first embodiment of the separation system 100 according to the invention, which is schematically illustrated in fig. 5, the droplet separator 6 is not arranged inside the container 7, but in the chimney itself and here in the vicinity of its discharge opening 10, unlike the prior art. The spraying device 5 is located near the upper end of the container 5. The module 13 shown in fig. 4, which comprises a plurality of plates 1, is arranged flat, so that the inflow surface F extends transversely to the flow direction of the exhaust gases R.
In order to fasten the module 13 in the chimney S, a replacement receptacle 21 is provided, which is designed in such a way that the module 13 is exchangeable during operation of the marine diesel. This replaceability is possible in particular during operation, since the modules are arranged in the chimney such that gas that may be discharged in the region of the replacement receptacle 21 during the replacement process reaches the environment directly.
In the second embodiment of the separation system 200 according to the invention, which is illustrated in fig. 6, the modules 13, in contrast to the first embodiment of the separation system 100 according to the invention, are arranged such that they form, with respect to the flow direction of the exhaust gas, a V-shape or an inverted V-shape ("roof-shape") with the respectively adjacent module. The inflow surface F of the module 13 therefore extends obliquely to the flow direction of the exhaust gas R. Furthermore, in the upper region of the container 7, also referred to as "absorption head", a plurality of layers of rolling separators 22 are arranged. The rolling separator has the following functions: on the one hand, the amount of liquid droplets in the exhaust gas is reduced and on the other hand the oil-containing components are captured and bound before they reach the module 13. The separation performance of the separation system can be further improved and the cleaning cycle prolonged by means of the rolling separator. In other respects, this second embodiment of the separation system 200 corresponds substantially to the first embodiment, so that reference is made to the description of the first embodiment.
