Description

The invention relates to the field of energy and transport engineering and can be used to drive consumers of mechanical energy, as well as an integral part of an internal combustion engine, including gas turbine engines (GTE) of a complex thermodynamic cycle for various purposes.
In a modern rotary machine drive, heating of the working fluid should be provided, which is relevant for direct-drive direct drives that require large torques at a low speed. The machine, depending on the version, can be used for the initial promotion of gas turbine rotors at start-up, propeller drives of aircraft power plants and ship propellers, as well as for power plants of locomotives, in industrial power engineering, etc. Such machines belong to the class of rotary machines of volume type with the use of liquid and gaseous working fluids with high pressure, including gases, vapors, air-fuel mixtures, etc.
A rotary machine is known comprising a three-section housing with a rotor and two spacer wheels housed in it kinematically connected to each other. The rotor is located in the middle section of the housing, is equipped with two blades that overlap the working channel, and is equipped with side walls bounding the working channel. At least in one of the side walls in the areas adjacent to the pressure surfaces of the blades, windows are made, while in the end walls of the working chamber, reciprocal openings are made to which high pressure pipes are connected. The separator wheels are installed in the extreme sections of the housing with the working channel overlapping along the line of contact of their cylindrical surfaces with the rotor.
/ RF patent No. 2135778, F01C 1/08, publ. August 27, 1999 / / 1 /
The disadvantages of the known device is that: the inlet / outlet of the high-pressure working fluid is carried out through windows made in the side walls of the rotor and reciprocal openings in the end walls of the working chamber, which have a very limited size. This leads to higher hydraulic losses and increased time when filling (pushing) a gaseous working fluid, ceteris paribus. The presence of bounding side walls in the device significantly increases the conjugate area of movable and fixed structural elements, which leads to an increase in the flow of the working fluid from volumes with higher pressure to volumes with lower pressure and friction losses of these surfaces, thereby reducing the efficiency of the device and its manufacturability design, and the limited use of the internal cavities of the rotor and the housing as the working volumes of the device does not allow to realize the potential awns invention.
A gas-rotor drive is also known, comprising a housing, in the bores of which are formed by intersecting cylindrical surfaces, two rotors are placed, mounted relative to the cylindrical walls of the housing with the formation of annular channels interconnected. The device also contains supply channels and a channel for removing the working fluid, made in the form of pipes. Each rotor is equipped with a recess and a profiled blade made reciprocal recess of the other rotor and with the possibility of overlapping the corresponding annular channel to separate it into the expansion zone and the exhaust zone of the working fluid. The presence in the rotor of the reciprocal recess for the profiled blade reduces the effective volume of the device.
/ (US Patent No. 3,472,445 A, F01C 1/12 publ. 10/14/1969) / / 2 /
The disadvantages of the known design is that the supply / withdrawal of the working fluid to the device, as in the previous solution, is through windows of limited dimensions, which leads to hydraulic losses and increases the time when filling (pushing) the gaseous working fluid, it is also not provided the use of internal volumes of rotors to accommodate the working fluid, which affects the overall mass, power and expenditure characteristics of the device as a whole.
Closest to the technical nature of the claimed device is a rotary machine of volume type, comprising a housing (1), at least one channel (8) for supplying / removing the working fluid and a spacer wheel (5) with a technological recess (6), a central body mounted in the internal cavity of the housing with the possibility of rotation around its axis and with a gap relative to the wall of the housing with the formation of an annular working (9) channel, a profiled element overlapping the supply channel, the protrusion (18) and the blade (4).
/ RF No. 2391514 C1, F01C 1/00, publ. 06/10/2010 / / 3 /
The disadvantages of this design is the presence of mating surfaces of a complex profile of the wheel-separator, which requires the use of special technological equipment to ensure their high-precision manufacturing and additional costs to maintain the necessary tightness during their operation. Other disadvantages are the significant dependence of the usable volume of the annular working channel of the device on the area of the longitudinal opening on the surface of the spacer wheel and the size of the partition wall of the housing and the formation of negative torque created by the spacer wheel due to the pressure difference of the working fluid acting on its part of the surface of a complex profile left and right partitions (expansion and exhaust zones) when mating their surfaces.
The expected technical result of the invention is the expansion of energy capabilities and increase the efficiency of its use, as well as improving manufacturability and reducing costs both in manufacturing and in operation.
The expected technical result is achieved in that the known volumetric rotary machine, comprising a housing (1), at least one channel (8) for supplying / removing the working fluid and a spacer wheel (5) with a technological recess (6), a central body, mounted in the internal cavity of the housing with the possibility of rotation around its axis and with a gap relative to the wall of the housing with the formation of an annular working (9) channel, a profiled element overlapping the supply channel, the protrusion (18) and the blade (4), characterized in that it is provided with a central a stationary collector (7) with at least one longitudinal window (16), the housing is stationary, and the central body is made in the form of a rotor (2) with an annular heating chamber (3) bounded by an external (12) shell with a longitudinal opening ( 13) and the inner (14) shell with a longitudinal slot (15), the heating chamber (3) is in communication with the opening (13) and the channel (8) for supplying / discharging the working fluid, while the profiled element is made on the inner (14) shell of the rotor (2) with the possibility of overlapping the longitudinal window (16), the spacer wheel (5) with technological height coy (6) is installed in the inner cavity of the housing between the wall of the housing and the rotor (2) with the possibility of rotation around its axis, and the blade (4) and the protrusion (18) are made on the outer (12) shell of the rotor (2), and the technological surface recesses (6), the wheel-separator (5) is associated with the mating surface of the protrusion (18). In the proposed rotary machine, the design of the central body provides the conversion of the energy of gas motion into its rotation. The central body is the rotor of the machine. The machine may include a heating chamber. The proposal allows the location of the heating chamber of a modular design in the inner cavity of the rotor, made with a Central hole in which a fixed hollow collector is installed with the possibility of periodic communication of its volume with the volume of the heating chamber.
The heating chamber module is limited by the side walls of the rotor and can include a flame tube (not shown in the figure) for organizing combustion, the structural elements of which perceive the main gas-dynamic and thermal loads associated with ignition and combustion of the air-fuel mixture.
To ensure the operability of the hot rotor and housing structure elements, a cooling system can be used in the device. For what a contour of the cooling system is formed, a regular working fluid can also be a coolant. At the same time, its separate supply to the heating chamber and the cooling system (not shown in the figure) is realized. After taking heat from the structural elements, the heated air is sent to the expansion zone for its subsequent mixing with the main stream from the heating chamber.
Moreover, after the cooling system, this part of the air can be used to form a fuel-air mixture of the second stage of heat supply (combustion) in the expansion zone.
The volume of the heating chamber is constantly communicated with the annular working channel through a longitudinal opening on the outer rim of the rotor and periodically with the collector through its cut-out and the opening on the inner rim that is compatible with it when the rotor rotates.
Moreover, the collector is connected to a source of compressed working fluid.
In contrast to the prototype, the use of the protrusion provides earlier contact of the rotor surfaces (along the edge of the protrusion) and the notch of the separator wheel, which allows to increase the working volume of the expansion with the formation of positive torque in a larger range of the angle of rotation of the rotor. From the moment the surfaces contact, an isolated volume of the expansion zone of the next working cycle is formed. The indicated volume is filled with a working fluid through the heating chamber and the process of its expansion is ensured.
In addition, the working fluid can enter the expansion zone through other channels, for example, from the cooling system of hot structural elements of the device.
The separator wheel is installed in the technological section of the annular working channel of the housing with the possibility of rotation about its axis and run in without sliding along the outer surface of the rotor to ensure tight contact at the point of contact of their cylindrical surfaces.
Moreover, for the mutual rotation of the rotor with the radial baffle and the separator wheel without biting and ensuring minimal gaps at the contact point, the latter is made with a technological shaped recess such as a recess for the passage of the baffle.
The cylindrical surfaces of the inner shell of the heating chamber and the collector with their periodically aligned cutouts during rotation of the rotor serve as a spool, through which another fresh portion of compressed air from the collector enters.
Additional regulation of the air supply can be made by turning the collector (or part thereof). The contact density between the mating surfaces is achieved due to the minimum technological gaps that ensure the application of mastered production technologies in their manufacture.
The tightness of mating cylindrical surfaces having the correct shapes of bodies of revolution, in addition to contact density, is also ensured by rolling friction of their surfaces rotated with equal linear speed along the contact line, as well as technological capabilities to improve accuracy in their production.
These measures ensure an acceptable level of flow of the working fluid (loss) from the expansion zone to the exhaust zone of the device.
The rotor is kinematically connected with the separator wheel, while the axis of rotation of the separator wheel and the axis of rotation of the rotor are installed in the same plane.
In the invention, the working volume of the expansion zone, in addition to the use of the protrusion on the rotor, increases due to the volumes of the “shaded” recess and the circumferential bore, along the channel of which, after the cavity of the recess is closed by the body boring, their volumes communicate with the annular working channel during the expansion stroke.
According to the invention, the cylindrical part of the rotor is located with a gap relative to the inner wall of the housing and the formation of an annular working channel in it, divided by a radial baffle and a separator wheel into zones of expansion and exhaust of the working fluid.
The expansion zone includes the volume of the annular working channel of the device between the separator wheel and the radial partition with the heating chamber, connected through a longitudinal window in the form of a cutout on the outer shell of the rotor, as well as the cavity of the notch of the separator wheel and the circumferential slot in the housing.
To increase the energy efficiency of the device, heat is supplied to the working fluid in the heating chamber and the isolated volumes connected to it. Moreover, to reduce the level of "pulsations" of the pressure of the combustion products and the "parasitic" stresses on the structural elements at the initial moment of expansion, the heat supply can be implemented in stages and carried out in different cavities. The first stage is at the beginning of the expansion stroke in a constant isolated volume. The next step is during the rotation of the rotor with a variable volume (similar to the Trinkler cycle), depending on the purpose of the device. Thus, the required torque on the rotor of the device can be provided by maintaining the necessary pressure differential on the radial baffle and its simple and uniform rotational movement.
In addition, a decrease in the differential pressure on the radial partition positively affects the decrease in the level of flow of the working fluid from the expansion zone to the exhaust zone of the device.
The connection of the heating chamber with the annular working channel is provided through a longitudinal cutout on the outer shell of the rotor constantly, and with the collector for supplying the working fluid periodically through the longitudinal slot (opening) on the inner shell of the rotor and the counter window on a fixed collector.
The device may be a valveless hybrid internal combustion engine (ICE) of a divided cycle with preliminary external compression of the working fluid, in the working volume of which, under certain conditions, the processes of inlet of the working fluid, heat supply, expansion stroke and exhaust gas flow alternately occur.
The combustion products, expanding in the working volume and acting on the radial partition, create torque on the rotor of the device and perform mechanical work.
Moreover, the exhaust gases with increased parameters, including the “loss” of the working fluid after overflowing from the expansion zone, can be directed through the exhaust zone for further use in a complex cycle of a power plant (for example, in a turbo-charged turbojet engine or power turbine, etc.).
The invention can be implemented and combined advantages (GTE) and piston engine in one design, which provides several advantages:
- simplicity of the power plant;
- uniform rotation of the working elements of the device is the complete absence of reciprocating movements of any type (linear, arched, planetary, etc.), and accordingly - there are no cyclically repeated accelerations and alternating inertial loads on engine parts, which allows to reduce weight and increase mechanical efficiency
- the implementation of continuous with a maximum level of torque on the rotor in almost the entire range of revolutions, which can significantly expand the scope of application of the device;
- the design of the device can provide a more complete expansion of the working fluid, which allows to realize increased thermal efficiency cycle;
- as a result of periodic heat supply, the short duration of exposure to high gas temperatures ensures the strength of structural elements with a greater thermal efficiency cycle;
For the proposed device scheme, there are potential opportunities to achieve rotational speed of the working shaft commensurate with the characteristics of a gas turbine engine, but with a corresponding significant increase in its power.
The proposed technical organization of the kinematic scheme of the device provides a direct and direct translation of simple and continuous rotation of the rotor into the rotation of the working shaft of the consumer drive and does not require the use of additional mechanisms to convert types of movement and does not need a special gas distribution mechanism, which is typical for engines of other classification groups. The complex function of the main body of the gas distribution mechanism is performed by the rotor itself.
The advantages of the device contribute to the application in industries that implement these advantages and especially in shipbuilding and industrial energy.
In the design and operation of the invention, used production technologies are used, as well as mastered cycles (ICE), consisting of the simplest thermodynamic processes.
The scheme allows you to eliminate the typical flaws of the classic ICE scheme and make the most of the perfection of compression, combustion and expansion of the working fluid in a gas turbine engine, as well as the positive qualities of their structural elements.
Reducing the energy loss of the working fluid in comparison with the prototype is achieved by:
- reduction of hydraulic resistance when moving the working fluid between the cavities as a result of increasing the area of the channels;
- increasing the tightness at the point of contact of the surfaces is achieved by the density of contacts between them by means of technological capabilities of manufacturing the device and providing rolling friction of cylindrical surfaces at the point of contact;
- increase the expansion stroke using an annular circumferential slot in the housing;
- exhaust gases with increased parameters with spurious leaks after the device can be sent for further use in the cycle of a power plant.
Improved adaptability and versatility of the rotary machine compared to the prototype is achieved by:
- exclusion of structural elements with surfaces of a technologically complex profile;
- the use of technologically simple structural elements of the device, including cylindrical and others in cross section of the correct form of bodies of revolution;
- simplicity and reduce the number of parts of the device.
The supply of the working fluid to the expansion zone of the device is carried out through a hollow rotor permanently connected to the annular working channel. In the inner volume of the rotor, the working fluid from the supply channel of the working fluid is periodically supplied through combined longitudinal slots on the fixed manifold and on the inner wall of the rotor.
All the main and most critical parts of the rotor device are simple figures of rotation, so they can be easily manufactured on standard metal cutting machines using the developed technologies.
The invention is illustrated in a schematic drawing (presented taking into account the rotation of the rotor clockwise):
The drawing shows a cross section of a rotary machine with two spacer wheels in an intermediate position of the structural elements of the device, in which the stage of filling the volumes with a working fluid (for example: gas) and the beginning of the expansion stroke are completed.
The rotary machine of volume type contains a housing 1, in the cylindrical bores of which there is a hollow rotor 2 with blades 4 and protrusions 18, shells 12 and 14 forming between it, a heating chamber 3, two spacer wheels 5 with a technological recess 6 and a collector 7 for supplying the worker body into the heating chamber 3 and the exhaust channel of the working fluid 8.
The cylindrical part of the rotor 2 is located with a gap relative to the inner wall of the housing and the formation between them of an annular working channel 9, divided by blades 4 and a spacer wheel 5 into the expansion zone 10 of the working fluid and the exhaust zone 11 of the spent working fluid.
The design of the hollow rotor 2 is technologically implemented in one piece with the heating chamber 3 in its internal working volume and with the blades 4, and the rotor is kinematically connected with the spacer wheel 5, and their rotation axis are made parallel (not shown in the figure).
The heating chamber 3 is enclosed between the outer shell 12 with the longitudinal opening 13 and the inner shell 14 with the longitudinal slot 15 and the side walls of the hollow rotor (not shown).
The heating chamber 3 is constantly communicated through the opening 13 on the outer shell 12 with the expansion zone 10 of the annular working channel 9, and is periodically connected through a longitudinal slot 15 on the inner shell 14 and the response longitudinal window 16 on the fixed collector 7.
To increase the working volume of the expansion zone 10 using the circumferential bore 17 in the housing, the cavity of the recess 6 of the wheel-separator communicates with the annular working channel after its overlapping (shading) by the circumferential bore of the housing.
After contact (interaction) of the surfaces of the protrusion of the rotor 18 and the recess of the wheel-separator 5, the volume of the expansion zone is isolated, it continues to be filled with a working fluid through the heating chamber. In accordance with the regulation program, heat is supplied to the fresh charge.
To balance the action of centrifugal and gas forces acting on the structural elements of the rotor and increase the torque, the device may include two or more spacer wheels, and the rotor, respectively, two or more blades (or the drive may include two or more sections mounted relative to each other under equal angles and other options).
The operation of the rotary machine volumetric type is as follows.
The collector 7 is constantly in communication with the source of the compressed working fluid.
The working fluid with increased pressure from the collector 7 periodically, through a compatible longitudinal window 16 on a fixed collector 7 and a slot 15 on the inner shell 14 enters the heating chamber 3.
In the process of filling the heating chamber 3, it is forced out of its volume of the spent working fluid from the previous cycle through the opening 13 into the annular working channel 9 and then into the exhaust working body 8 discharge channel.
Briefly, when combining the opening 13 with the channel 8, the spent working fluid displaced by the working fluid from the heating chamber 3 enters the exhaust zone 11 and ends after the interaction (contact) of the surfaces of the protrusion 18 begins with the recess 6 of the separator wheel.
From the moment of contact of the surfaces of the protrusion 18 with the recess 6 of the exhaust and expansion zones are insulated. This is the beginning of the expansion stroke process with the formation of positive torque.
The continuation of filling the volume of the expansion zone with the working fluid from the heating chamber 3 is ensured after the initial moment of interaction of the surfaces of the protrusion 18 with the recess 6 of the spacer wheel 5 and ends after the longitudinal window 16 on the manifold 7 and the longitudinal slot 15 on the inner shell 14 are mutually overlapped. counter longitudinal window 16 perform the function of a spool valve.
The heating chamber 3 through a constantly open opening 13 on the outer shell 12 is in communication with the expansion zone 10.
The expansion zones 10 are isolated, the heating chamber 3 is filled with a fresh charge of the working fluid, the longitudinal slots 15 are mutually overlapped, and the windows 16 from this moment conditions have been created for starting the supply of heat to the working fluid.
The expansion cycle process continues.
Fixed collector 7 is constantly connected to the expansion zone.
If it is necessary to increase the volume of the fresh charge of the working fluid in the cycle, the isolation of the heating chamber 3 from the fixed collector 7 is carried out with a later overlapping of the longitudinal slit 15 with the window 16 during the further rotation of the rotor. As a result, the working fluid fills an additional part of the volume to the left of the radial blade 4 (including the volumes of the recess 6, the circumferential bore 17 and the expansion zone 10 through the opening 13 from the heating chamber 8.
When using the air-fuel mixture as a fresh working fluid after filling the volumes of the heating chamber 8, the recess 6, the circumferential bore 17, and the expansion zone 10 (corresponding to the maximum insulated intake volume that acts as a combined combustion chamber), it ignites.
Moreover, the supply of heat to the working fluid in the device can be realized both at a constant volume, at a constant pressure or at a constant volume and pressure (Trinkler cycle), depending on the method of supplying fuel, forming and supplying the air-fuel mixture and other gases.
After igniting the air-fuel mixture in an isolated volume (combined combustion chamber) and increasing the working pressure, the process of expansion of the working gases in zone 10 occurs, providing rotational movement of the rotors 2 relative to the housing with the creation of a working level of torque.
Due to the pressure difference acting on the opposite surfaces of the blade 4, a torque is created under the action of which the rotor rotates (in the drawing, the rotor 1 rotates clockwise). The pressure of the working gases in zone 10 is many times higher than the pressure of the exhaust gases in zone 11.
Zone 11 of the annular working channel 8 is communicated through a longitudinal window (channel) 8 with a pipe outlet of the spent working fluid.
The process of expanding the working fluid in zone 10 occurs until the outer edge of the blade 4 is aligned with the longitudinal window 8.
When the rotor 2 is turned at a certain angle, the longitudinal slots 15 and the windows 16 are combined and the filling of the volume of the heating chamber 3 from the collector 7 begins with the next portion of the fresh charge of the working fluid.
The process (cycle) of the expansion of the working fluid in the working volumes of the combined combustion chamber is completed after the radial partition 4 passes through the opening 8, at which exhaust gases are released from the internal volume of the heating chamber.
And then, in a similar way, a repeated (next) cycle of the device operation begins.
In the device, using the protrusion 18, the expansion stroke and the range of action of the torque on the rotor are significantly increased.
The volumetric rotary machine provides a simple and uniform rotational movement of the rotor and its main working elements.
The use of the proposed volumetric rotary machine provides a more efficient conversion of the potential energy of a high-pressure working fluid into mechanical work compared to well-known analogues, including an increase in efficiency, an improvement in specific mass and overall parameters, an increase in its speed, as well as an improvement in manufacturability and cost reduction as in manufacturing and in operation.
