Invention Title: PRESSURIZATION SYSTEM FOR SELF-SUSTAINABLE ENERGY GENERATION

Introduction

[0001] The present invention patent specification refers to a

Pressurization System for Self-Sustainable Energy Generation, hereinafter referred to as Pressurization System, which corresponds to a system for energy generation with closed circuit operation that only needs a cistern with water or oil for its operation and clean energy generation with low operating and maintenance costs, being able to operate anywhere, occupying a minimum space, without the need for sun and wind and also, without harming the environment and nature, consisting of generator cylinders or tanks pressure, pressurized cylinder, reservoir, inlet pipes, outlet pipes, pressure valve and transducers, hydraulic and electric motors, injection pump, check valve, pressure sensor, register with actuator and PID system or Derivative Integral Proportional Controller.

Application field

[0002] The field of application of this Pressurization System is wide and diverse, mainly when producing energy by capturing water from artesian wells, fish farming tanks, water treatment plants - ETA, Water Treatment Plants Sewage - ETE, from the increase in pressure in the drinking water distribution networks, generation of energy with water or oil and other applications, generating its own energy source.

Purposes

[0003] Among the main purposes of this Pressurization System, we must highlight the implementation of a clean energy generation system with low operating and maintenance costs. Problem to solve

[0004] The biggest problems to be solved, as is well known among technicians in the area, stems from the fact that currently all existing systems to generate energy are large and difficult to maintain, as well as having very high costs, both in terms of energy production and maintenance.

State of the art

[0005] Analyzing existing and known problems and aiming at placing on the market a clean energy production system equipped with

characteristics of development, previous research was carried out with the INPI Database and the following document was found:

[0006] BR 10 2014 029765-0 deposited on 11/28/2014 under the title "Energy Generator and Energy Generation System", which comprises a combustion engine (1), which is connected to an energy generator (2) and this to a power transformer (3), the output of the power transformer (3) being connected to a control and distribution panel (4) which, in turn, has a phase connected to an air compressor (5), said air compressor (5) with the outlet connected to a pneumatic device (6), having a pressure switch (7) at the air outlet for said pneumatic device (6). The generation of energy starts from the combustion engine (1), through which the energy generator (2) connected to the input of the energy transformer (3), said energy transformer (3) having output to the control and distribution panel (4) which has a phase feeding the motor (19) of the air compressor (5), designed to generate the amount of air up to the maximum capacity of said air compressor (5), which is connected to the pneumatic device (6) coupled to the aforementioned energy generator (2), so that, once the maximum pressure load of the air compressor (5) is reached, the control and distribution panel (4) receives command to automatically , turn off the internal combustion engine (1), with the system generating energy from the

supply of the pneumatic device (6) to the energy generator (3). [0007] From the comparative analysis between the document found in the State of the Art and the Pressurization System, now on screen, it appears that the two processes are totally different, which is why it is considered that there are no

technical or legal impediments to grant the requested privilege.

Detailed description of the invention

[0018] As can be inferred from the drawing that accompanies and forms an integral part of this report, Pressurization System, (1), corresponds to the system developed for the generation of clean energy with closed circuit operation that only requires a cistern with water or oil for its operation and clean energy generation with low operating and maintenance costs, being able to operate anywhere, occupying a minimum space, without the need for sun and wind and also, without harming the environment, being formed by a cooling unit (A) in which the cylinders (2) or pressure generating tanks, pressurized tank (3), reservoir (4), inlet pipes (5), outlet pipes (6), valves (7), power (8), motors, hydraulic (9A) and electric (9B), check valve (10), pressure transducer (11), pressure regulating valve (12) PID system (13), automatic switchgear (14) and pump (15).

[0019] In this way, the Pressurization System (1) is constituted in its form

preferred installation by three steel tanks, two of which (2) are intended to generate pressure and the third tank (3) for pressurization or pressure accumulator, also has an oil reservoir (4) and

4 cistern containing water or oil, noting that the tanks (2) and (3) are closed and have equal dimensions, height, diameter and capacity.

[0020] The System (1) has valves (7), preferably 1 ”, which will serve to start the operation of the system (1), that is, it will give the initial start as follows:

a) With an energy generator to supply the alternating current motor; b) Another way to start the machine is by feeding the mains

concessionaire activating the alternating current motor;

c) And through a battery running a direct current motor.

[0021] The System (1) has an automatic distribution board (not shown) that controls and drives the hydraulic motor (9), a 24 V and 75 Am battery for starting, in addition to a steering wheel, a generator, a sensor pressure (11) and PID system (13).

[0022] The System (1) is characterized by the fact that it works with water or oil to generate pressure and provides itself with increased pressure and flow. This happens because of the hydraulic motor (9) and the three tanks, two pressure generators (2) and a pressurizer (3) totally closed as well as an oil reservoir (4), allowing, when the System is activated (1) , that is, the generator (not shown), the hydraulic motor (9) and the PID system (13), perform the suction of water or oil from the reservoir (4), operating in a closed circuit, and thus injecting into the water tanks. pressure generation (2), which in turn starts the pressurization process, while this function happens, it is automatically transferred to the third tank, (3), of pressurization, which builds up this pressure.

[0023] In this way, the pressure generating tanks (2) receive the initial process from the hydraulic motor (9), when the pressure has already been transferred to the third tank (3), where there are only two exits, an output that will return to the reservoir (4) and to the hydraulic motor (9) to increase its efficiency and the other to drive the generator shaft with the handwheel (8) that will drive a generator (not shown). [0024] Therefore, this generator will have a frequency inverter that will automatically activate an automatic switchboard (14) that controls the valves and sensors that act as informants for this process for the automatic switchboard, highlighting that the check valves (10) its function is to maintain the safety of the system in case of an unforeseen leakage in the piping and other cylinders and hydraulic motor (9) that will activate the pressurization system in the tanks.

[0025] It is worth noting that the PID System (13) automatically performs the rotation reading to control the flow, pressure and to keep the generator shaft in operation, and the automatic switchboard (14) is responsible for activating the motors and control of them, starting now with more or less power, according to the need to reset the pressure in the cylinders, it is also necessary to emphasize that the automatic panel readings are performed on the pressure transducer (1 1) that informs the PID system (13 ) that controls the pressure regulating valves (12), opening and closing to activate more or less torque in the generator.

[0026] The reservoir (4) closes the flow circuit, remaining below the energy generator (8), with the hydraulic motor (9) being activated at any time necessary to suction the liquid from the reservoir (4).

[0027] In turn, the generator is activated when the System starts (1) to have control with the hydraulic motor (9), pressure transducer (1 1), PID system (13) and generator shaft ( 8) generating energy for the electronic components of the System (1), noting that the cylinders work with 250% of the torque needed for the initial start, the first cylinder has a 50% accumulation, the second with 150% and third with 250%, requiring only 30% of the value of the third cylinder, noting that after the completion of these processes, 90% of its energy sufficiency for consumption is generated.

Operation and testing

[0028] The operation was carried out using a Hydraulic Generator conformed with the following characteristics and components: - Provided with its pressurization system;

- Equipped with a 60 kVA generator connected to the hydraulic system;

- Another 25 kVA diesel generator to drive the hydraulic generator;

- 15 kV electric motor.

[0029] According to the above components, the way of functioning occurs as follows:

- The external generator of 25 kVA, activates the electric motor of 15 kW, which in turn, activates the hydraulic of the generator of 60 kVA.

[0030] The tests and trials were carried out on an electronic resistive load bank and a non-electronic resistive load bank and an inductive load bank, that is, aiming at obtaining a power factor and correction, depending on the types of load.

[0031] The results obtained can be analyzed on the test sheets

respective.

[0032] It is common knowledge that a 25 kVA generator has a consumption of 8 liters of diesel oil / hour. According to this parameter, the 60 kVA generator in the Hydraulic System attached to it should spend 14 L of diesel oil / hour, but due to the hydraulic and pressurization system in the equipment, diesel consumption has been reduced.

[0033] The active power is the capacity of the circuit to produce work in a

period of time. Due to the reactive elements of the load, the apparent power, which is the product of the voltage by the circuit current, will be equal to or greater than the active power. Reactive power is a measure of stored energy that is returned to the source during each cycle of alternating current. It is the energy that is used to produce the electric and magnetic fields necessary for the operation of certain types of loads, for example, industrial rectifiers and electric motors.

[0034] The power factor is expressed by: cos fi = P / S [(Watt) / (VA)].

[0035] The power factor is determined by the type of load connected to the system

electrical, which can be: - Resistive Circuit = Voltage (V) and current (I) waves in phase. The load has a resistive characteristic (FP = 1). Phase angle cp = 0 °.

- Inductive Circuit = Current wave (I) delayed in relation to the voltage wave (V). The load has an inductive characteristic FP <1 (delayed).

- Capacitive Circuit = Current wave (I) advanced in relation to the voltage wave (V). The load has capacitive characteristic FP <1 (in advance).

[0036] By definition, the power factor is a dimensionless number between 0 and 1.

When the power factor is equal to zero (0), the energy flow is entirely reactive, and the stored energy is returned completely to the source in each cycle. When the power factor is 1, all the energy supplied by the source is consumed by the load. The power factor is usually marked as delayed or forward to identify the phase angle signal between the electric current and voltage waves.

[0037] If a purely resistive load is connected to the system, the current and voltage will change polarity in phase, in which case the power factor will be unitary (1), and electrical energy will flow in the same direction through the system in each cycle . Inductive loads such as motors and transformers

(equipment with coils) produce reactive power with the current wave delayed in relation to the voltage. Capacitive loads such as capacitor banks or buried electrical cables produce reactive power with an advanced current in relation to the voltage.

[0038] Briefly summarizing the values graph, it is concluded that in the 30

minutes of test loads were applied to the generator up to the maximum limit of the production generator (60 kVA), which after exceeding this value lost the alternator excitation due to the AVR (Generator electronic control module that only allows exceeding the maximum limit for 8 minutes).

[0039] Comparing the values of input consumption with that produced, it is concluded that the production of energy is greater than that available to consume.

[0040] The production cannot be summarized only in the energy produced in kVA, but in the sum of kVA and kVAR (reactive energy), therefore, and analyzing the graph, we can see that the sum of the two is in the 128 (kVA + kVAR); This reactive energy is due to the fact that the load bank has an electronic control that produces this effect, otherwise there would be an effective energy production of 60 kW, since we have purely resistive loads, whose coefficient of fi = 1 (active energy production maximum to 60 kVA).

[0041] As proof of what has been described, the list of tests, trials and

results are:

Conclusion

[0042] It is verified by everything that has been described and illustrated that it is a Pressurization System for Self-Sustainable Energy Generation (1), which fits perfectly within the rules that govern the Patent of Invention, and must complete important gap in the market, deserving for what was exposed and as a consequence, the privilege requested.
