Description

AN ENERGY GENERATION SYSTEM

TECHNICAL FIELD

The present invention relates to an energy generation system which provides generation of electrical energy from movement energy which occurs during movement of a fluid which moves in a closed cycle.

PRIOR ART

One of the most important issues which must be taken into account in studies related to providing energy efficiency is to recover the waste heat which occurs as a result of processes. In various systems, waste heat energy released to atmosphere is recovered by using various systems, and energy saving is provided.

Organic Rankine Cycle (ORC) is an ideal technology for heat recovery in industrial applications. In an opposite manner to the heat recovery systems based on traditional vapor Rankine cycle, ORC eliminates the requirement of purifying water and adding water and provides transformation in closed system.

In ORC, waste heat is taken by means of an exchanger and is applied to fluid gases or liquids whose kinetic is rapidly changed, and kinetic energy of waste heat is increased. With this increasing kinetic energy, structures like turbine, etc. are rotated and this rotational energy can be directly used or can be used as electricity by connecting to a generator. The biggest disadvantage of this known art is that high temperatures are needed for generating energy since the efficiency of cycle is low. This system cannot be operated with high efficiency at temperatures between 30-200^eC which can be described as low temperature for energy recovery. Therefore, these systems can be used only in heavy industries or with waste heats where the geothermal sources are very strong. This leads to substantially limited usability of such systems.

In the present art (in ORC and in similar systems), heat transfer is realized by means of water and similar fluids, and heat is transferred to other fluid. This leads to usage of extra equipment (exchanger, pump) and leads to usage of more amount of fluid (water, etc.) which shall be in circulation. Because of these reasons, problems occur like high cost in the system, and low efficiency due to the losses which occur during transfer of weight and heat directly without an agent.

Besides, since the turbines used in ORC systems operate under high temperature and pressure, abrasions occur in turbine fins and turbine shaft over time, and this leads to decrease of efficiency of the system. In such systems, since the most costly equipment is turbine, this condition increases maintenance and operation costs and leads to decrease of reachability.

As a result, because of the abovementioned problems, an improvement is required in the related technical field.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

The present invention relates to an energy generation system (10) which provides generation of electrical energy from movement energy which occurs during movement of a fluid which moves in a closed cycle.

With reference to Figure 1 and 2, in said energy generation system (10), electrical energy is generated from the mechanical energy gained by a fluid heated by means of a heat supply. In a possible embodiment of the present invention, a waste heat supply is preferred to be used as said heat supply. In an alternative embodiment of the present invention, as said heat supply, heat is formed as a result of burning of combustible substances like fuel, etc. The fluid, heated in heat supply provided in closed cycle and transformed into gas phase, is transferred to an energy generation unit (200). Said energy generation unit (200) provides generation of electrical energy from the movement energy of the heated fluid. In a possible embodiment of the present invention, the energy (700) generation (10) (200) unit is operated as a generator, etc. The energy generation unit (200) comprises a fixed body (201). In a possible embodiment of the present invention, said body (201 ) is provided from a structure like metal, etc. There is a fixed coil (202) placed such that a radius is formed which gradually enlarges as from a beginning point and placed to the center point of said body (201). There is a movable coil (203) placed in a manner contacting around the fixed coil (202) by means of the rotational movement applied concentrically as said fixed coil (202). In a possible embodiment of the present invention, said coil structures comprise a metal structure which is similar to a spring. As a result of movement of the movable coil (203), the inner surface of the movable coil (203) is provided in a manner connected to the outer surface of the fixed coil (202). As a result of movement of the movable coil (203), the movable coil (203) and the fixed coil (202) approach each other but do not contact each other. This condition prevents abrasion of the two parts as a result of heat and pressure over time and provides a long usage lifetime. The movable coil (203) is placed in a manner diverging from the fixed coil (202) from the beginning point towards an end point. The fixed coil (202) has a beginning point and an end point. In the same manner, the movable coil (203) has a beginning point and an end point. There is a first opening (204) which allows entry of fluid through the opening which remains between the end point of the movable coil (203) and the end point of the fixed coil (202). There is a second opening (205) which allows output of fluid, which enters through said first opening (204), from the beginning point depending on the movement of the movable coil (203). The energy generation unit (200) provides generation of electricity from movement energy which occurs by means of pressure which increases depending on compression during movement of the fluid, which enters through the first opening (204), towards the second opening (205). There is an energy storage unit (206) for storing the energy generated by means of the energy generation unit (200).

With reference to Figure 2, there is a condenser (300) which provides condensing of the fluid for providing liquefying of the fluid which exits the energy generation unit (200). There is a fluid storage unit (400) for storing the fluid which exits the condenser (300) in liquid phase. There is a pump (500) provided between the fluid storage unit (400) and the heat supply for providing movement of the liquid fluid, stored in the fluid storage unit (400), to the heat supply. There is a power supply (700) for providing the energy needed for the initial operation of said pump (500). In a preferred embodiment of the present invention, while the power supply (700) is used for the initial energy, the pump (500) is continued to be operated by means of the energy obtained as a result of operation of the energy generation system (10). Thus, the energy generation system (10) provides the energy needed for operating itself. This facilitates efficient usage of energy. There is a control unit (600) configured to control operation of the energy generation system (10).

With reference to Figure 2, the control unit (600) is embodied to provide movement of the fluid which is in closed cycle. There is at least one frequency equalizer provided for increasing the resistance of the energy generation unit (200) operated by means of the control unit (600). Said frequency equalizers provide operation of the energy generation unit (200) at fixed momentum by providing realization of the momentum speed adjustment of the energy generation unit (200). This provides fixation of the difference between the temperature of the fluid, which enters the energy generation unit (200), and the temperature of the fluid which exits the energy generation unit (200). Thus, the energy generation system (10) can stay stable.

An exemplary operation scenario of the present invention is hereunder described;

The control unit provides operation of the pump (500) by means of the energy received from a power supply (700). The initial movement of the energy generation system (10) begins by operating the pump (500). Said movement can be provided in an on-grid and/or off-grid manner from the power supply (700). As a result of operation of the pump (500), the fluid, which exists in the fluid storage unit (400), is provided to move in a pressured form. The fluid, which passes through the pump (500), is heated as a result of the effect of temperature in the heat supply, and the fluid gains kinetic. The fluid, heated in the heat supply (100), is transformed from liquid form into gas form. The fluid, which is heated in the heat supply (100) and which gains kinetic and which changes form and passes to gas phase, is provided to enter the energy generation unit (200) through the first opening (204). The fluid, which passes through the first opening (204), is provided to move towards the second opening (205) by means of the movement of the movable coil (203). The fluid, which approaches the second opening (205), is pressurized by means of the effect of compression. The speed of the fluid increases depending on pressure. This provides rapid expansion of the fluid. The expanded fluid is provided to exit the second opening (205) of the energy generation unit (200). As the fluid is compressed from the first opening (204) towards the second opening (205) and as the speed and pressure of the fluid increase, the rotation of the movable coil (203) becomes continuous. In other words, the fluid is taken from the first opening (204) again as the fluid goes from the first opening (204) to the second opening (205). This provides continuous suctioning and rapid rotation of the energy generation unit (200). Thus, depending on the movement of the energy generation unit (200), electricity is generated from the increasing rotation speed. The generated electrical energy is stored in an energy storage unit (206). In an alternative embodiment of the present invention, the generated electrical energy is fed back to the pump (500) and the energy generated during the following operations of the pump (500) can be used. In another alternative embodiment of the present invention, the mechanical energy generated in the energy generation unit (200) can be used for providing movement energy to a movable system. The fluid, which exits the second opening (205) of the energy generation unit (200), is provided to enter the condenser (300) and is condensed. The fluid, which changes phase by condensing and which becomes liquid again, is transferred to the fluid storage unit (400) in order to be stored. The liquid fluid, stored in the fluid storage unit (400), is provided to be included again to the energy generation system (10) by means of the effect of the pump (500). The energy generation system (10) continuously operates until a stop signal is received from the control unit (600). In this case, energy can be continuously generated. In a possible embodiment of the present invention, there can be a user interface embodied to provide data entry to the control unit (600). Thus, the operation and/or stopping of the energy generation system (10) can be controlled in a remote manner. The data exchange between the control unit (600) and the user interface can be provided by means of a communication unit. The communication unit is provided in a manner communicating in a wired and/or wireless manner.

In an exemplary embodiment of the present invention, the energy generation system (10) is operated in a remote manner by means of a mobile application provided to a user mobile device. The control unit (600) provides operation of the pump (500) by means of the energy, received from the mains, depending on the beginning signal received from mobile device. As the pump (500) is operated, the fluid, stored in a fluid tank, is provided to move towards the pump (500). The fluid, which passes through the pump (500) and which is accelerated, is heated by means of a waste heat supply. The fluid, which is heated and which changes phase in the waste heat supply, is transformed from liquid form into gas form. The fluid, transformed into gas form, enters through the first opening (204) of the scroll turbine. The fluid moves from the first opening (204) towards the second opening (205) depending on the movement of the movable coil (203). The fluid, which is compressed and pressurized towards the second opening (205), is expanded. The expanded fluid leaves the scroll turbine through the second opening (205). The movable coil (203), which expands and accelerates by means of the movement of the fluid, provides fluid entry again through the first opening (204). Thus, movement continues and continuity is provided. Movement energy, obtained by means of continuous rotation of the movable coil (203) of the scroll turbine, is transformed into electrical energy. Electrical energy is stored in order to be used in a battery. The fluid, which exits the second opening (205) of the scroll turbine, enters the condenser (300) and condenses and is transformed from gas form into liquid form again. The fluid, transformed into liquid form, is transferred to the fluid tank in order to be stored. The liquid, taken from the fluid tank by means of the movement of the pump (500), is transferred to the waste heat supply. The energy generation system (10) continues until a stop signal is transferred from the mobile application to the control unit (600). In this case, the system is controlled in a remote manner. Moreover, energy is generated as needed.

In an alternative embodiment of the present invention, in case a failure occurs in at least one of the structures which operate on the energy generation system (10), a warning signal can be transferred to the user interface by means of the control unit (600). Thus, a failure condition which can occur in the energy generation system (10) can be eliminated in short duration. This can prevent damaging of the operating structures.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
