1 is a conceptual diagram illustrating a turbocharger generator 100 according to an embodiment of the present invention.

Referring to FIG. 1, the turbocharger generator 100 includes an exhaust pipe 110 connected to a diesel engine 150 to which exhaust flows.

The exhaust pipe 110 is fastened to one side of the diesel engine 150. The exhaust pipe 110 guides the combustion products generated in the diesel engine 150 to the outside.

 The turbocharger generator 100 includes a turbine 120 disposed in the exhaust pipe 110. The turbine 120 includes at least one blade (not shown) that rotates by the exhaust.

One side of the turbine 120 is coupled to the drive shaft (not shown) is coupled to the compressor (C). At this time, when the at least one blade is rotated by the exhaust, the compressor (C) compresses the intake air.

 The turbocharger generator 100 includes a turbocharger generator motor 140 fastened to one side of the transmission 130. The turbocharger generator motor 140 performs a role of a generator or a motor according to the direction of rotation.

For example, when the turbocharger generator motor 140 rotates in the first direction, it performs the role of a generator, and when the turbocharger generator motor 140 rotates in the second direction opposite to the first direction, it serves as a motor. Can be done.

On the other hand, the turbocharger generator 100 includes a transmission 130 in conjunction with the turbine 120. The transmission 130 may be formed in various ways. In this case, the transmission 130 may be formed in a pulley shape. In addition, the transmission 130 may be formed of a plurality of gears (not shown).

The transmission 130 is disposed on one side of the turbine 120. The transmission 130 is variable according to the driving of the turbine 120. Thus, the transmission 130 operates to be suitable for driving the turbine 120.

For example, the transmission 130 converts the rotational speed of the blades of the turbine 120 to a constant rotational speed capable of generating electricity in the turbocharger motor 140 when the blades of the turbine 120 rotate at high speed. To the turbocharger generator motor 140.

On the other hand, when the blades of the turbine 120 rotates at a low speed, the transmission 130 rotates the turbine 120 by the turbocharger generator motor 140 by separating the turban 120 and the turbocharger generator motor 140. This prevents it from slowing down.

In addition, the transmission 130 may change the direction of the rotational force transmitted from the turbine 120 to the turbocharger motor 140 to transmit. The transmission 130 may change the direction of the rotational force transmitted from the turbocharger generator motor 140 to the turbine 120 and transmit the same.

 Looking at the operation of the turbocharger generator 100, the diesel engine 150 is driven when a vessel (not shown) is operating. At this time, the compressor C compresses the intake air and supplies it to the diesel engine 150.

The diesel engine 150 mixes and burns the compressed intake and diesel. The diesel engine 150 is driven by thermal energy due to the combustion.

Meanwhile, combustion products are generated inside the diesel engine 150 by the combustion of the diesel and the intake air. The combustion product is discharged to the exhaust of the diesel engine 150.

The exhaust is guided to the outside through the exhaust pipe (110). At this time, the exhaust collides with the blades of the turbine 120. The blades rotate by the exhaust.

When the blades rotate, the rotational force is transmitted to the transmission 130. In this case, the transmission 130 transmits the rotational force to the turbocharger generator motor 140.

The turbocharger generator motor 140 rotates in the first direction by the rotational force. At this time, the turbocharger generator motor 140 generates electric energy while rotating in the first direction.

The electrical energy is transmitted to each part of the vessel to supply the electrical energy necessary for the operation of the vessel.

Therefore, through the exhaust generated from the diesel engine 150 it can be efficiently produced and supplied to the vessel. In addition, it may absorb and utilize a portion of the energy contained in the exhaust.

2 is a conceptual diagram illustrating a turbocharger generator 200 according to another embodiment of the present invention.

Referring to FIG. 2, the turbocharger generator 200 includes an exhaust pipe 210, a turbine 220, a turbocharger generator motor 240, and a transmission 230, as described above with reference to FIG. 1.

 The turbocharger generator 200 may further include an electrical storage unit 270 electrically connected to the turbocharger generator motor 240. In addition, the turbocharger generator 200 may further include a converter 260 disposed between the electrical storage unit 270 and the turbocharger generator motor 240.

The electrical storage unit 270 may include all means and an apparatus for storing electrical energy generated by the turbocharger generator motor 240. For example, the electrical storage unit 270 may include a secondary battery (not shown).

The electrical storage unit 270 may temporarily store the electrical energy generated by the turbocharger generator motor 240 as chemical energy. In addition, the electrical storage unit 270 may convert the chemical energy stored in the turbocharger generator motor 240 into the electrical energy and supply the converted electrical energy.

On the other hand, looking at the operation of the turbocharger generator 200, the diesel engine 250 is driven in accordance with the operation of the vessel.

When the diesel engine 250 is driven, the intake and the exhaust are generated as described with reference to FIG. 1.

The exhaust is discharged to the outside through the exhaust pipe 210. The exhaust rotates the blades of the turbine 220. At this time, the blades rotate forward. The rotational force generated while the blades rotate forward is transmitted to the turbocharger generator motor 240 through the transmission 230. In this case, the turbocharger generator motor 240 generates the electrical energy while rotating in the first direction. The electrical energy is transmitted to the converter 260. Converter 260 converts the electrical energy from alternating current to direct current.

The electrical energy converted into direct current is transmitted to the electrical storage unit 270. The electrical storage unit 270 converts the electrical energy into the chemical energy.

At this time, the electrical storage unit 270 stores the chemical energy. The electrical storage unit 270 converts the chemical energy into the electrical energy, if necessary, and transmits the electrical energy to a required portion of the vessel.

Meanwhile, the turbocharger generator 200 may further include a rotation speed sensing unit 221 for sensing the rotation speed of the blades of the turbine 220. In addition, the turbocharger generator 200 may further include a diesel engine load detection unit 251 for detecting the rotation speed of the shaft (not shown) of the diesel engine 250.

In addition, the turbocharger generator 200 may operate the turbocharger generator motor 240 or the turbine 220 based on the number of revolutions detected by the rotation detector 221 or the load sensed by the diesel engine load detector 251. It may include a control unit 290 for controlling. The controller 290 may control the transmission 230 and the electrical storage unit 270.

The rotation speed sensing unit 221 senses the rotation speed of the blades when the blades of the turbine 220 rotate. The rotation speed detection unit 221 detects the rotation speed and transmits it to the control unit 290.

The controller 290 controls the turbocharger generator motor 240 to produce the electrical energy based on the rotation speed. For example, when the rotation speed is determined to be less than or equal to the first rotation speed, the controller 290 generates the transmission 230 in the turbine 220 so as not to produce the electrical energy in the turbocharger generator motor 240. The rotational force is controlled not to be transmitted to the turbocharger generator motor 240.

Meanwhile, when the rotation speed is less than or equal to the first rotation speed, turbo lag may occur. At this time, the amount of exhaust gas is low in the low speed range of the diesel engine 250 so that the blades of the turbine 220 rotates slowly, thereby reducing the supercharge amount. Therefore, when the turbo leg is generated, the diesel engine 250 may have a phenomenon in which the supercharge amount is limited until the proper rotation speed is reached.

In this case, the controller 290 controls the electrical storage unit 270 to supply the electrical energy from the electrical storage unit 270 to the turbocharger generator motor 240. The turbocharger generator motor 240 rotates in the second direction to generate a rotation force. The controller 290 controls the transmission 230 to supply the rotational force generated by the turbocharger generator motor 240 to the turbine 220.

In this case, the controller 290 controls the transmission 230 to supply the rotational force to the turbine 220 in the same direction as the rotational direction of the blade of the turbine 220.

For example, when the rotation direction of the turbocharger generator motor 240 is in a direction opposite to the blade rotation direction of the turbine 220, the control unit 290 may change the direction of the rotational force transmitted to the turbine 220. ) Can be controlled.

On the other hand, the control unit 290 when the rotation direction of the turbocharger generator motor 240 is the same direction as the blade rotation direction of the turbine 220, the transmission 230 so as not to change the direction of the rotational force transmitted to the turbine 220 Can be controlled.

The turbine 220 may receive the rotational force to rotate the blades. Thus, the turbine 220 effectively operates the compressor C.

On the other hand, when the rotation speed exceeds the first rotation speed and less than the second rotation speed, the control unit 290 stops the turbocharger generator motor 240 and the transmission to separate the turbine 220 and the turbocharger generator motor 240. After controlling 230, turbine 220 is operated in its original state.

That is, the turbine 220 operates the compressor C only by the exhaust exhausted from the diesel engine 250.

In this case, the first rotational speed and the second rotational speed may be set differently from each other. In addition, the first rotation speed may be set smaller than the second rotation speed.

On the other hand, if the rotation speed exceeds the second rotation speed, the control unit 290 controls the turbocharger generator motor 240 to generate the electrical energy as described above.

At this time, the transmission 230 converts the rotational speed of the blades of the turbine 220 to a constant rotational speed capable of generating electricity in the turbocharger generator motor 240 to supply to the turbocharger generator motor 240. The turbocharger generator motor 240 rotates in the first direction to generate electrical energy.

At this time, the control unit 290 is a transmission (to change the direction of rotational force transmitted to the turbocharger generator motor 240, if the rotational direction of the turbocharger generator motor 240 is opposite to the blade rotation direction of the turbine 220) 230 can be controlled.

In addition, when the rotation direction of the turbocharger generator motor 240 is the same direction as the blade rotation direction of the turbine 220, the controller 290 does not change the direction of the rotational force transmitted to the turbocharger generator motor 240. 230 may be controlled.

The electrical energy is stored in the electrical storage unit 270 via the converter 260. Therefore, the electrical energy can be stored and easily supplied when necessary.

On the other hand, the diesel engine load detection unit 251 detects the rotational speed of the shaft of the diesel engine 250 when the diesel engine 250 operates. The diesel engine load detection unit 251 detects the load of the diesel engine 250 based on the rotation speed of the shaft.

The diesel engine load detection unit 251 transmits the detected load to the control unit 290. The controller 290 controls the turbocharger generator motor 240 to generate the electric energy based on the load.

For example, when it is determined that the load is 35% or less, the controller 290 controls the electrical storage unit 270 to supply the electrical energy from the electrical storage unit 270 to the turbocharger generator motor 240.

At this time, the turbocharger generator motor 240 is driven by the electrical energy. The turbocharger generator motor 240 generates the rotational force by rotating in the second direction by the electric energy.

The rotational force is supplied to the turbine 220 through the transmission 230. In this case, the controller 290 controls the transmission 230 to supply the rotational force to the turbine 220 in the same direction as the rotational direction of the blade of the turbine 220.

For example, when the rotation direction of the turbocharger generator motor 240 is in a direction opposite to the blade rotation direction of the turbine 220, the control unit 290 may change the direction of the rotational force transmitted to the turbine 220. ) Can be controlled.

On the other hand, the control unit 290 when the rotation direction of the turbocharger generator motor 240 is the same direction as the blade rotation direction of the turbine 220, the transmission 230 so as not to change the direction of the rotational force transmitted to the turbine 220 Can be controlled.

On the other hand, if the load is greater than 35% and less than 90%, the control unit 290 controls the turbocharger generator motor 240 not to produce the electrical energy. In this case, the controller 290 controls the transmission 230 not to transmit the rotational force generated by the turbine 220 to the turbocharger generator motor 240.

When the load exceeds 90%, the controller 290 controls the turbocharger generator motor 240 to produce the electrical energy. In this case, the turbocharger motor 240 is rotated in the first direction to produce the electrical energy.

Meanwhile, the controller 290 controls the transmission 230 to supply the rotational force generated by the turbine 220 to the turbocharger generator motor 240.

At this time, the control unit 290 is a transmission (to change the direction of rotational force transmitted to the turbocharger generator motor 240, if the rotational direction of the turbocharger generator motor 240 is opposite to the blade rotation direction of the turbine 220) 230 can be controlled.

In addition, when the rotation direction of the turbocharger generator motor 240 is the same direction as the blade rotation direction of the turbine 220, the controller 290 does not change the direction of the rotational force transmitted to the turbocharger generator motor 240. 230 may be controlled.

On the other hand, the electrical energy is supplied to the electrical storage unit 270 via the converter 260. The electrical storage unit 270 converts and stores the electrical energy into the chemical energy.

On the other hand, when the rotational speed of the blades is less than the first rotational speed or the load is 35% or less as described above, the rotational speed of the blades of the turbine 220 is sharply reduced.

At this time, when the rotation speed of the blades is rapidly reduced, the exhaust is not smoothly discharged. Therefore, the efficiency of the turbine 220 is reduced, and the performance of the compressor C is lowered.

As the performance of the compressor C decreases, the compressed intake air cannot be supplied, thereby degrading the performance of the diesel engine 250. Therefore, when the condition is satisfied, the controller 290 controls the turbocharger motor 240 to rotate in the second direction to perform a role of a motor.

Meanwhile, referring to the case in which the turbocharger generator motor 240 performs a role of the motor, the controller 290 controls the turbocharger generator motor 240 and the electric storage unit 270 as described above.

When the load of the diesel engine 250 is 35% or less, or the rotational speed of the blades is less than the first rotational speed, the control unit 290 is the turbocharger generator motor 240 is the electrical storage from the electrical storage unit 270 Control to be supplied.

In this case, the controller 290 controls the electrical storage unit 270 to convert the chemical energy into the electrical energy to supply. The electrical energy is converted from direct current to alternating current through the converter 260.

The electrical energy converted into alternating current is transmitted to the turbocharger generator motor 240. In this case, the controller 290 controls the turbocharger motor 240 to perform the role of a motor by rotating in the second direction by using the electrical energy.

The turbocharger generator motor 240 generates a driving force by the electric energy. In this case, the driving force is transmitted to the transmission 230. The controller 290 controls the transmission 230 to vary the rotation speed of the blades of the turbine 220 based on the driving force. In this case, since the control method of the transmission 230 is performed in the same or similar manner as described above, a detailed description thereof will be omitted.

Meanwhile, the controller 290 receives the rotation speed of the blades through the rotation speed detection unit 221. The control unit 290 controls the transmission 230 to convert the magnitude of the driving force into the feedback of the rotational speed and supply it to the turbine 220.

When the turbine 220 is deteriorated as described above, the turbine 220 is further accelerated and driven by receiving the driving force. In this case, the transmission 230 drives the blades so that the blades have a suitable rotational speed.

Therefore, the blades ensure a proper rotation speed to smoothly exhaust the exhaust. In addition, the compressor C can easily compress the intake air by the rotation of the blades.

The compressed intake air is supplied to the diesel engine 250 to increase the efficiency of the diesel engine 250. Therefore, the turbocharger generator 200 improves the performance of the diesel engine 250. In addition, the turbocharger generator 200 may effectively utilize the exhaust discharged to the outside.

Meanwhile, the turbocharger generator 200 may include the turbocharger generator motor 240 and the turbine based on at least one of the rotation speed detected by the rotation sensing unit 221 and the load sensed by the diesel engine load detection unit 251. At least one of 220 may be controlled. Since the method of controlling the turbocharger generator 200 is performed in the same or similar manner as described above, a description thereof will be omitted.

Therefore, the turbocharger generator 200 may effectively utilize exhaust exhausted to the outside.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
