Abstract

The present invention relates to an electric energy Micro Generator, integrated by a pneumatic motor and an electric Generator coupled magnetically, where the pneumatic motor is propelled by the fluid pressure associated with: air, natural gas, bitter gas, nitrogen, etc. designed to be intrinsically safe, with an index of protection against intrusion of solid objects or dust, accidental contacts, or water IP 67, according to the International Electro technical Commission, for use in hazardous locations “where fire or explosion may exist due to flammable gases or vapors, flammable liquids, combustible dust or flammable fibers or in suspension”. “Classified as Class I, Division 1, Group A, B, C and D, according to U.S. National Electrical Code, and which has its main field of application remote installations that lack electricity, but that dispose of a pressure associated with a fluid.

In this regard, it is important to mention that:

• • The pressure associated with the propellant fluid can be as low as 5 Kg/cm2 and as high as up to at least 700 kg/cm2;
  • The implementation of magnetic coupling ensures that there is no possibility that the fluid used as propelling means, the high pressures associated with said fluid, the pneumatic motor and none of the pieces that integrated it, have contact and/or enter the space of the electric generator and
  • The fluid used as propelling means is not consumed, is returned to its original process, providing a sustainable and intrinsically safe process.

Claims

1. A Micro Generator, of electric energy characterized to be composed of a pneumatic motor and an electric generator coupled magnetically:

wherein the pneumatic motor comprises a compartment which houses the pneumatic system integrated by the rotor, the blades, the internal magnetic shaft, the internal magnets and bearings and the engine compartment cover of the pneumatic motor;

wherein the electric generator includes the electric generator as such and the external magnetic coupling, which are housed inside the compartment, and front covers as well as rear to complement the isolation of the power system with the environment; and

which consists in operating the pneumatic motor using as a propellant the pressure associated with a fluid, causing the rotor and the blades to rotate eccentrically moving the internal magnetic shaft, which, finding the magnets attached to both internal of the pneumatic motor, as with the external magnetic coupling of the electric generator, moves the electrical generator at the same speed.

2. The electric energy Micro Generator of claim 1, wherein the bearings of the pneumatic motor are ceramic.

3. The electric energy Micro Generator claim 1, wherein the pressure associated with the propellant fluid is greater than or equal to 5 Kg/cm2 and less than or equal to 700 kg/cm2.

4. The electric energy Micro Generator of claim 1, wherein the pneumatic motor is filled with a fluid under pressure and functions as a chamber that completely isolates it from the electrical system and only allows it to be magnetically coupled to the electrical generator, ensuring that there is no possibility that the fluid used as propelling means, the high pressures associated to said fluid, the pneumatic motor and none of its parts that integrate it, have contact and I or penetrate into the space of the electric generator.

5. The electric energy Micro Generator of claim 1, characterized as a means of driving any type of fluid used:

corrosive, poisonous, wet, etc., containing liquid or particles not exceeding 0.001% of the volume of the propulsion chamber.

6. The electric energy Micro Generator of claim 1, characterized in that the fluids used are preferably:

air, natural gas, bitter gas, nitrogen and CO2.

7. The electric energy Micro Generator claim 1, wherein the fluid used as propelling means is not consumed, but returns to its original process.

8. The electric energy Micro Generator claim 1, wherein the electric generator, being completely isolated from the pneumatic motor, operates in a casing pressurized with an inert gas, with a degree of protection against intrusion of solid objects or dust, accidental contacts, or water IP 67, according to the International Electro technical Commission, (IEC) for use in hazardous locations classified as Class I, Division 2, Group A, B, C and D, according to U.S National Electrical Code.(NEC)

9. The electric energy Micro Generator claim 1 wherein nitrogen is used, for the pressurization of the casing of the electric generator, uses preferably nitrogen.
