Description

[Detailed description of the invention] The present invention relates to a gas turbine separator assembly for use.

For example, the separator assembly of the present invention is particularly useful as a water vapor and/or particle separator for removing water vapor and/or particulate matter contained in air entering the air intake of a marine vessel turbine.

For gas turbines for marine use, where water vapor particles in the air generally contain salts which, if introduced into the turbine, would have a detrimental effect on the turbine components, e.g. by chemical corrosion. A water vapor separation device is provided. Additionally, dry particles such as sand and/or salt crystals contained in the air can cause "pitting" of turbine components if not removed. By far, however, it is the water vapor particles that contain salt.

Although various types of separator assemblies have been proposed for maritime use that minimize the passage of such air-laden air to the turbine, it is noted that this is of substantial importance. Should. In practice, this means that air must always be delivered to the turbine, even if this means delivering air laden with water vapor and/or salt, which may damage turbine components. It is so important that

Conventionally, therefore, the "blower" is automatically opened when the pressure drop across the steam separator becomes too large, i.e. beyond a predetermined limit and the turbine becomes starved of air flow. Doors or passageways known as doors have been proposed. According to these conventional devices,
A system in which unfiltered air enters the air duct and bypasses the steam separator to the turbine.

This increased pressure drop when passing through a steam separator is due to the fact that steam separators for marine gas turbines are typically located high on the ship, where they are not protected from the elements.
can result from freezing or freezing of the water vapor separation device when the vessel on which the device is installed is in cold or icy water. For example, water vapor removed from the air by a water vapor separator can freeze within the water vapor separator, which significantly impedes the flow of air through the water vapor separator and increases the pressure drop as it passes through the water vapor separator. This causes a reduction in the amount of air sent to the turbine.

Thus, in the prior art, when this occurs, an auxiliary "blower" door or passageway is automatically opened by detecting or sensing the increase in pressure differential across the water vapor separator.

As can be appreciated, such a separate auxiliary door requires the manufacture of different parts and the provision of separate air passages in the air duct, and the air duct and separation device assembly for the marine gas turbine increase the size and weight of Furthermore, having two separate passages and two separate parts in the separate passages makes the device quite complex, bulky and cumbersome.

These and other disadvantages are due to the fact that the air intake of the turbine installation is movable itself or at least in part in the air duct to allow the air to bypass the separation device and be introduced directly into the turbine. This is overcome by the present invention, which provides a simple 4-item device for inlet ducts. In particular, in accordance with the present invention, a separator assembly includes a separator for removing particulate matter contained in passing air, and at least a portion of the separator at a filtration position and a bypass position within an air duct. and a mounting device for mounting the separation device within the air duct for movement between the separation device and the air duct. The separation device is arranged such that substantially all of the air passing through or entering the air duct passes through the separation device when the movable part is in the filtering position, and when the movable part is in the bypass position. The arrangement is such that air passing through the air duct when present bypasses at least the movable part of the separation device without passing through it. A sensing device is provided for sensing the pressure difference of the air as it passes through the separation device in the air duct. Further, a device is provided responsive to the sensing device for moving the movable portion of the separator to a bypass position when the pressure difference sensed by the sensing device increases above a predetermined pressure difference. In this way, the necessary air flow to the turbine system is maintained.

In particular, according to a preferred embodiment of the invention, a frame arrangement is provided for supporting the separator, said mounting arrangement being arranged in a first position and a first position corresponding to the filtration position and the bypass position of the separator. Serves for mounting the frame device to move within an air duct between two positions. That is, the mounting device is preferably positioned such that the separation device is positioned substantially perpendicular to the flow of air into the air duct and the separation device is positioned so that the air flows around the separation device. a swivel mounting device for pivotably mounting the frame device for movement between a vertical filtration position and a second position in which the frame device is bypassed and directly fed to the turbine; It is configured.

The pivot mounting device may include a pair of bin members mounted on opposite ends of the frame device in alignment with each other so as to be pivotable about an axis passing through a pair of pin members, The frame device may include a hinge device along a line of the frame device for pivotally hingedly supporting the frame device within the air duct.

In each of these embodiments, the frame device is placed in a vertical position that is releasable in response to a pressure sensing device that causes the frame device to pivot or swing freely in response to the flow of air drawn into the air duct. A suitable ramp arrangement is provided to maintain the filter vertically in position.

In still other embodiments, the separation apparatus includes first and second separation stages, the second separation stage preferably hinged to the first separation stage and the second separation stage preferably hinged to the first separation stage. It is movable relative to the -th separation stage between a position arranged vertically with respect to the -th separation stage and a detour position inclined with respect to the -th separation stage. This arrangement is similar to the other arrangements described above, except that the air passing through the air duct is partially separated by the first separation stage.

These and other features will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate preferred embodiments.

According to the drawings in which the same reference numerals represent the same elements, the first
The figure shows a separator assembly 10 according to the invention for an air intake duct 12 for a turbine installation (not shown). The turbine arrangement may include, for example, a gas turbine, but may be used with other types of turbines. The separator assembly 10 of the present invention is also particularly useful as a water vapor separator for use in gas turbines of marine vessels or other amphibious vehicles, and will therefore be described with reference to such use. However, the separator assembly 10 of the present invention desirably filters particles contained in the air introduced into the turbine through the air intake duct 12 and is unfiltered to prevent starvation of air to the turbine. It should be understood that it may also be used in environments where it is necessary to allow air to bypass the separation device.

In gas turbines for offshore use, the turbine draws air into the air intake duct 12 through a steam separator 14 to supply the desired amount of air to the turbine.
It works like this. Generally, air ducts are located high up in ships or vehicles so that the air introduced into the gas turbine contains as little water vapor as possible. In such cases, the water vapor separator 14 is typically mounted at the intake 16 to the air duct 12.

Typically 2000 cubic feet/second (approximately 56.7 d/sec)
The air flow to be introduced into the turbine in such offshore applications is required to be on the order of magnitude greater than 2 seconds). Dependent on the speed of air flow through it. For example, as the flow velocity through the air intake duct 12 increases, the cross-sectional area of the duct 12 (and the size of the duct 12) increases.
can be substantially reduced. On the other hand, the pressure drop across the water vapor separator 14 disposed in the air intake duct 12 is at an acceptable level, i.e.
(approximately 15.2 cm) or less. Since the pressure drop across the steam separator 14 is dependent both on the flow resistance created by the steam separator 14 itself and on the flow rate therethrough, the pressure drop satisfies the requirements for a given bulk flow rate. serves as a limit to the increase in flow velocity that can be achieved. Therefore,
Since it is desirable to reduce the size of the air duct 12 (to save cost, weight and size), the water vapor separator 1 is designed to have as low a flow resistance as possible.
It is desirable to configure 4. At the same time, however, the reduction in flow resistance created by the water vapor separator 14 must be done without impairing the efficiency of removing water vapor particles from the air passing through the water vapor separator 14. For example, in many marine applications, high flow velocities through the steam separator, on the order of 20 feet/second (approximately 6.1 m/second) or more, are desirable.

These parameters, as discussed above, provide the necessary bulk flow to the turbine and at the same time the steam separator 14.
The exact configuration for the turbine's air system 14 and the size of the air intake duct 12 itself becomes determined so as to maintain the pressure drop across the turbine at an acceptable level.

However, it is intended that the water vapor separator 14 be located within the air intake duct 12 in an environment where it will not become clogged or freeze, i.e. located at an elevated location on the ship. Despite this configuration, there is still the possibility that the steam separator 14 will become clogged during operation. As can be appreciated, such blockage increases the flow resistance created by the steam separation device 14 to the flow of air into the air intake duct 12 of the gas turbine. Since the bulk flow rate to the turbine is dependent on the resistance provided to the flow of air into the air intake duct 12, as the resistance provided by the steam separator 14 increases, the amount of air flow directed to the turbine increases accordingly. It can be seen that there is a decrease in Since sufficient intermittent air must be delivered to the turbine at all times, if the steam separator 14 becomes clogged or the resistance it provides increases beyond an acceptable level, the required air flow to the turbine will be interrupted. It is necessary to provide some device for bypassing the steam separator 14 in order to send the water vapor.

Accordingly, as discussed in the introduction, conventional "air blowers" include a separate door or component that automatically opens when the pressure drop across the steam separator 14 increases beyond a set limit. ”The door was ready. This thus allows unfiltered air to flow into the air duct 12 bypassing the steam separator 14 to be sent to the turbine. According to the invention, the steam separator 14 itself or at least a portion thereof However, this “air blow” is applied to the filter assembly 10.
is movably mounted within the air duct 12 so as to eliminate the need for a separate "blast" door in communication with the air duct to bypass the water vapor separator 14.

Further, in accordance with the general principles of the present invention, as seen, for example, in FIGS. 1 and 2, the separator assembly 10 is mounted at the inlet 16 of the air intake duct 12 to the gas turbine. The end 16 of the air intake duct 12 remote from the turbine is preferably attached to and connected to the air duct 1
opening 19 defining an inlet for air flow into 2;
It includes an inlet locoper plate 18 having a. The water vapor separator 14 is installed in the air intake duct adjacent to the opening 19 of the cup ζ-plate 18 and is positioned so as to surround the inlet opening 19 in the air intake duct 12. Substantially all the air drawn into the steam separator 1
4 is sized to correspond to the size of the inlet opening 19 . Additionally, the steam separator 14 is such that air passes around the steam separator 14 and passes directly to the gas turbine, bypassing the steam separator 14 as the pressure drop therethrough increases beyond a predetermined value. It is mounted so that it can be moved or opened away from the inlet opening 19. Thus, an improved separator assembly 10 is provided which is not as bulky as conventional devices and which maintains a flow of air to the turbine under virtually all conditions.

In the embodiment shown in FIGS. 1 and 2.

A steam separator receives unfiltered air that is drawn into the air intake duct 12 to filter and treat the unfiltered air to remove particulate matter such as water vapor and salt prior to induction into the turbine. For this purpose, a two-stage water vapor separation device is provided at the inlet end 16 of the air intake duct 12.

The first stage of the steam separator 14 includes a conventional inertial separator 20 through which the air flow to be introduced into the turbine initially provides partially treated air. The inertial separation device 20 may, for example, consist of a plurality of chevron-shaped or square-shaped vanes 22 oriented vertically and arranged closely together. However, it should be understood that other types of inertial separators may be used, such as cyclone separators. The plurality of blades 22 are supported by a support frame member 24 that surrounds the blades 22 and holds the upper and lower ends thereof in a fixed position.

As the air passes through the vanes 22, it must turn around several times to follow the path between the tops of adjacent vanes 22. Particles contained in the air, such as water vapor particles containing salt, sand, or other particulate matter, are generally larger agglomerates than air particles, so that the particles move towards the blades 22 due to the centrifugal force acting on them. Thrown outward when changing direction relative to a surface. That is, lighter air particles may be redirected through the series of crests, while heavier mass particles may do so, with larger particles impinging on the surface of the vane 22. ...each of the tops of the roots 22 may include a stop to prevent impinged particles from being re-entrained by the aerodynamic drag forces exerted by them sliding along the surface of the vane 22 into the air flow. .

Such an arrangement is particularly useful for removing heavier particles contained in the air, since such particles tend to impinge on the vanes and be removed from the air stream. On the other hand, lighter particles may have a tendency to successfully pass through the flow path and remain contained in the air. For example, this selective separator or filtration device 20 may be used in the high flow velocity range associated with a steam separator 14 for a gas turbine, i.e.
It has been found that a speed range of 0 feet/second (approximately 6.1 m/second) or more is effective in removing water vapor particles with a size of 8 microns or more. However, the plurality of blades 22
did not show high efficiency for removing water vapor particles in the smaller droplet range, i.e. 8 microns or less. Therefore,
It may be desirable to use other filtration stages or devices to remove such smaller particles.

In this regard, in the embodiment shown in FIGS. 1 and 2, after being partially treated by the first stage 20 of the steam separator 14, the air is further processed to remove the particles contained therein. Second stage 26 that helps treat the air
will be introduced in For example, this second stage 26 of the steam separator 14 may include one or more layers, each constructed from a number of fiber elements or wires. The layers of fibrous elements are arranged in a circumferential frame member 28 arranged vertically in the first stage 20 by any suitable method, such as by adding a second stage frame member 28 downstream of the first stage frame member 24. is housed within. The second stage 26 is preferably configured to remove smaller particles contained in the air to provide well-treated air from which substantially all water vapor particles and other particulate matter have been removed. There is.

Although the preferred embodiment of the invention described herein only includes a two-stage steam separator 14, additional separation stages may be provided and arranged in tandem downstream of the first two stages. It should of course be understood that it can be mounted with Of course, specific configurations of the water vapor separator 14 are possible depending on the particular situation and environment in which the water vapor separator 14 is placed and the desired characteristics for the treated air.

However, according to the present invention, the number of stages is kept to a minimum while the removal efficiency of water vapor particles is maximized to minimize the size and weight of the water vapor separator 14 in the air intake duct 12. The preference should be acknowledged. In this regard, increasing the number of stages generally increases flow resistance (7) and increases the weight of the device, which is undesirable as discussed above.

Further, according to the embodiment shown in FIG. 1, the steam separation device 14 is constituted by vertically aligned pin members 30, 32 provided on the upper and lower surfaces of the first stage frame member 24. It is rotatably supported within the air duct 12 for vertical rotation about an axis. These pin members 36, 32 are each received in a suitable socket provided on the upper and lower inner surfaces of the air duct frame 12. In this way, the water vapor separation device 14 is configured such that substantially all of the air introduced into the air duct 12 must pass through the first and second separation stages 20.26. It can be arranged in a filtration position perpendicular to the direction of air flow (see FIG. 1).

The water vapor separator 14 can also be pivoted to a detour position that is inclined with respect to the direction of air flow (see Figure 2).
.

In this bypass position, as best seen in FIG. Ru.

In this embodiment shown in FIGS. 1 and 2, the first stage frame member 24 has at its forward or upstream end one side of the bin member 30.3'2 (FIGS. 1 and 2). 2) and an inner flange portion 40 on the other side (left side in FIGS. 1 and 2) of the bin member 30.32 to separate the water vapor. It will be appreciated that the device 14 is freely pivotable clockwise from the filtration position to the bypass position as shown in FIG. In the filtration position, this 7-run section 38
．． 40 serves to seal the inlet opening 19 to the air duct 12.

Therefore, during normal operation on a ship, all air flow into the turbine air intake duct 12 must pass through the steam separation device 14.

This is the position shown in FIG. However, if icing occurs or the steam separator 14 becomes clogged, covered, etc. (something actually provided by the steam separator 14 that significantly increases the flow resistance), the pressure drop across the separator 14 increases. The pressure drop across this separation device 14 may be detected by suitable devices such as, for example, pressure sensors 46, 48 and differential pressure sensors or switches 42. When the high limit is reached, a suitable locking or clamping device 44 is automatically actuated to release the separator 14 from its filtration position (second
(see figure).

In particular, this pressure sensing device may include the usual components conventionally used to sense the pressure differential across the water vapor separator 14 and to operate the "blower" door. For example, the pressure sensing device has one side connected to the air duct 12.
It may also include a pair of pressure sensors or pressure tubes 46, 48, one located inside the air duct and the other located outside the air duct, ie receiving atmospheric pressure.

A suitable force differential pressure switch 42 receives the output from each pressure sensor 46,48 to measure the differential pressure of the air flowing through the water vapor separation device 14 introduced into the air intake duct 12. For example, the differential pressure switch 42 has a pressure of 6 inches (approximately 15 inches) in the water column.
．． Typically, the clamping device 44 is automatically actuated to release the clamping or locking force for holding the steam separator 14 in the filtration position when a high limit of pressure drop, such as 2 cm) or more, is reached. It is suitably connected to a lock or clamp device 44 that holds the steam separator 14 in the filtration position.

In the embodiment shown in FIGS. 1 and 2, this clamping device 44 is a two-position clamp mounted on the inner surface of the air intake cover plate 18 and movable between a first and second position. Contains equipment. This movement can be caused by electrical, pneumatic or hydraulic devices. In the first position, the clamping device 44 connects the water vapor separator 14 to the inlet opening 19 to the air duct 12 such that all air flow has to pass through the water vapor separator 14 and into the air intake duct 12. It is adapted to engage the inner seven flange portions 40 of the first stage frame member 24 to lock in the overlying position.

This clamping device 44 is movable to a second position in response to a differential pressure switch 42 that senses a high limit of pressure drop to release the holding force on the steam separation device 14. As the pressure difference across the steam separator 14 increases, the steam separator 14 swings over the bin 30.32 and the second
Air is directed into the duct 12 around the sides of the steam separator as shown.

In this regard, the outside of the air duct 12 and the air duct 1
The bins 3°, 32 are attached to the frame member 24 of the first stage so that the action of the pressure difference experienced by the steam separator 14 between the insides of the bins 30, 32 causes the separator 14 to swing about the bin 30, 32. It will be noted that there is a slight offset with respect to the vertical centerline.

This swing opening action ensures that sufficient air is always delivered to the gas turbine.

In order to prevent the water vapor separator 14 itself from freezing in the opening 19 of the air duct 12, a separate "
A suitable heater (not shown) may be provided around the opening 19 to prevent freezing as is common with blower doors.

Embodiments of the invention, such as that shown in FIGS. 3 and 4, move the water vapor separator 14' to a position where the air introduced into the air duct 12 is forced to completely bypass the water vapor separator 14'. The pond configuration of the separator assembly 10' is shown operative for displacement. In this embodiment as well, the steam separator includes a two-stage steam separator in which a first stage 20' and a second stage 26' are both fixedly arranged in tandem. two joined stages 20', 26
' is used to pivot the steam separator 14' backwards and upwards so that the entire steam separator 14' directs the air flow around the bottom and side edges and into the air intake duct 12. The air intake duct 12 is hingedly supported within the air intake duct 12 so as to be swingable about a horizontal axis extending along the upper surface or edge of the air intake duct 12 . Each one board 5
2 is secured to the frame member 24' of the first stage 20' of the steam separator 14', and the other plate 54 is secured to the inner surface of the intake loca- tion plate 18' adjacent the upper edge of the opening 19'. A plurality of hinges 50 are provided. According to other configurations, one continuous hinge may be provided extending over the entire width of the steam separator 14'. In this regard, the forward or upstream end of the first stage frame member 24' is provided with a seal adapted to seal around its inlet opening 19' against the inner surface of the air space ε5 manpower bar plate 18'. 7 langes 56 around its periphery. The water vapor separator 14' typically has an air intake opening 19 such that substantially all air flow must pass through the water vapor separator 14' and into the air intake duct 12.
are kept coextensive with respect to ′. The water vapor separator 14' includes, for example, an air intake cover plate 18
The introduction of a suitable lock or flange device including a pivotable ramp device to abut and flange the bottom flange member 56 of the first stage frame member 24' against the air separation device The flange member 56 of the steam separator 14' is moved, for example by pivoting rearwardly, to cause the entire separator 14' to pivot rearwardly and upwardly so as to pass around the bottom and lower side edges of the steam separator 14'. is suitably operable to disengage the . As in the embodiment of FIGS. 1 and 2, the flange arrangement 44' of the embodiment of FIGS. 3 and 4 is operated by a differential pressure switch to move the flange arrangement 44' to an unlocked position. It is operable in response to a sensed predetermined upper limit pressure difference. Therefore, in the embodiments shown in FIGS. 3 and 4, this differential pressure switch and detector are not particularly shown, but as in the embodiments shown in FIGS. It may be a model.

Figures 5 and 6 show that the air duct 1 even in frozen conditions.
2 shows a third embodiment of a separator assembly 10'' that operates so that the internal air flow is partially filtered.

In this embodiment, the steam separator 14'' includes a two-stage steam separator 14'' in which a first stage 20'' and a second stage 26 are both typically arranged in tandem. There is.

However, in this embodiment, the second stage frame member 28'' is attached to the first stage frame member 24'' by a hinge member 60 such that the second stage 26'' is pivotable with respect to the first stage 20''. It is supported on a hinge. It is fixedly supported within the first stage fret 12. Suitable ramps or locks are provided to normally maintain the first stage 20# and second stage 26'' adjacent to each other in a plane substantially perpendicular to the flow of air passing through the air intake duct 12. A device 44'' is provided. This clamping device 44'' is, for example, configured so that the end of the bin member 62 is connected to the frame member 28 of the second stage.
It may include a slidable pin member 62 that is movable to a locked position so as to be received in a suitable recess in a block 64 secured to the block 64 (see FIG. 6).

If the pressure difference across the water vapor separator 14'' exceeds a predetermined limit, it is detected by a suitable differential pressure switch and detector (not shown), so that the clamping device 4
4' is simply actuated to release the holding force or clamping force on the second stage 26'' with respect to the first stage 20#. When this occurs, the introduction of flowing air into the air intake duct 12 is The air passes only through the first stage 20" and into the second stage 2.
The second stage 26'' is pivoted upwardly around the hinge member 60 from the first stage 20'' so that it flows over the lower bottom and side edges of the second stage 6''.

In each of the different embodiments shown in FIGS. 1-6, as soon as differential pressure switch 42 detects that the differential pressure across steam separation device 14 is above a predetermined limit, It should be noted that the clamping device 44 is released. Due to air flow resistance by the steam separator 14, the steam A force is created in the steam separator that causes the separator 14, or a portion thereof, to pivot or rock from its filtration position (substantially perpendicular to the air flow). In this regard, when the steam separator 14 (or portion thereof) is pivoted or moved to a bypass position, the resistance to air flow through the displaced steam separator 14 (or portion thereof) is Since the displaced steam is substantially greater than the resistance to flow around the separating device 14 (or the displaced portion thereof), substantially all of the air flow is around the moving portion of the steam separating device. Do not pass through it. Thus, substantially all or a large portion of the air flow bypasses the portion of the steam separator 14 that is displaced.

This is disadvantageous from the point of view of filtering particulate matter from the air, as the requirements for feeding air to the turbine, unfiltered air, are more important with respect to preventing serious damage to the turbine. However, the separator assembly IO of the present invention desirably ensures that air flow is maintained to the turbine under virtually all conditions.

Thus, according to the present invention, the steam separator 14 itself is
It will be appreciated that the system includes a blower door and a separator element for filtering the air during normal operation. As can be appreciated, this reduces the number of parts required to manufacture and maintain.

and, among other things, result in the elimination of separate "blower" doors or entry passages required by the prior art, reducing manufacturing costs, weight,
Minimize size, etc.

In addition, in the preferred embodiment described above, the separation device 14 (!,
The movement of the bamboo (part of the bamboo shoots) into the bypass position may occur simply as a result of the release of the clamping device 44, such that the air flow itself causes a swirling or rocking movement of the separating device 14, but a forced movement may occur. The device or auxiliary device is the filtration element 14
When the pressure difference across the water vapor separator 14 exceeds a predetermined limit, the forced movement or auxiliary device is activated to force the separator 14 to the bypass position. Air duct 12 as if sweeping

It will be appreciated that it is the separation device itself that is moved to the bypass position, whereas a separate door or inlet path to the air intake duct is opened, as in the prior art.

It will be recognized that this will be provided. The separation device assembly 1
0 includes a separation device 14 for removing particulate matter contained in the air passing therethrough, and at least a portion of the separation device 14 is movable within the air duct 12 between a filtering position and a bypass position.
