Description

  The present invention relates to an internal combustion engine for power generation that can utilize combustible powders.

  Conventionally, natural gas and oil have been used as an internal combustion engine for power generation, but the power generation efficiency is low and it is mainly used as a small-scale emergency power source.

  As fuels for power generation, natural gas, oil, and coal have problems with global warming and exhaust gas, nuclear power has safety, where hydropower can be used, and wind power and sunlight have problems.

  Therefore, there has been a demand for a power generation device that can use renewable, inexpensive, clean fuel, and has high electrical conversion efficiency.

  For this reason, ethanol and oil were extracted from plants that are storages for sunlight energy. However, a large amount of energy was required for the extraction, and a power generation device with high electrical conversion efficiency that directly uses plants was demanded.

  Conventionally, in order to increase power generation efficiency, the explosive combustion power of fuel and its residual heat have been used. However, if flammable powder is used as an inexpensive fuel, a large amount of ash and carbides are generated, and the power generator is continuously connected. I couldn't drive.

  For this reason, a power generation apparatus with high activation efficiency that uses the explosive combustion power and residual heat of a mixture of dry powder such as grass and oil, which is an inexpensive fuel, and algae that produces oil, and air, has not been achieved.

  The present invention is intended to solve the problems of such a conventional configuration, and provides an internal combustion engine that uses, for example, plant dry powder as a fuel, which cannot be used directly in the past. It is intended to increase the efficiency of power generation by turning the steam turbine and generating combined cycle power generation.

  In order to achieve the above object, the present invention prevents the ash and carbide generated when combustible powder is burned from clogging between the cylinder and the piston of the internal combustion engine, and the ash and carbide accumulated in the internal combustion engine. In order to facilitate efficient removal, the piston is not moved directly by the explosive combustion force of the mixture of combustible powder and air, but is moved through the liquid.

  The exhaust gas from the internal combustion engine is led to a centrifugal separator, and the ash and carbides are efficiently and continuously removed, and then led to a boiler that rotates a steam turbine.

  Since the internal combustion engine of the present invention takes the above-described form, the piston does not clog the piston by the explosive force obtained by exploding and burning the mixture of combustible powder and air in the cylinder through the liquid. Can be taken out as exercise

  A large amount of ash and carbide generated in the cylinder efficiently and continuously extract liquid and exhaust gas in the internal combustion engine with a centrifuge.

  When converting solar energy into electricity, solar energy is always stored in plants, so the conversion efficiency to electricity and the utilization efficiency that can generate electricity when needed are improved compared to direct conversion to electricity.

  Since the hard trunks of plants are softened and the soft parts are used as fuel by simply drying and pulverizing them as they are, energy utilization efficiency and fuel production efficiency are improved.

  The power generation using the internal combustion engine of the present invention can operate the internal combustion engine of the present invention with explosive combustion power using dry powder of the plant as a fuel, and can turn the steam turbine using the residual heat of the exhaust gas, resulting in high power generation efficiency. ing.

  When the mixture of dry powder and air explodes in the cylinder of the internal combustion engine of the present invention, the expansion direction of the gas is only the direction of the liquid, that is, the layer direction of the ash and carbide deposited on the surface of the liquid. The scattering direction of ash and carbide generated by explosion combustion is also the same direction, and the inner wall of the cylinder is not damaged by the scattering of ash and carbide.

  Since the mesh-like movable partition wall is installed in the cylinder of the internal combustion engine of the present invention, ash and carbides are deposited on the upper part of the cylinder, and the layer has a large heat insulating effect, and hardly any heat is transferred to the liquid below it. Also, the steam between the layer and the cylinder becomes a lubricant, and the frictional resistance is very small.

  Controlling the size of the holes in each part of the reticulated movable partition controls the amount of ash and carbide layers flowing into the underlying liquid. Even if the mixing ratio of combustible powder and air is changed, the amount of generated ash and carbide changes, and the thickness of the ash and carbide layer deposited on the mesh-like movable partition wall in the cylinder is changed. I can control it.

  If the periphery of the upper part of the cylinder in the internal combustion engine of the present invention is cooled with water from the boiler, the utilization efficiency of the residual heat is improved.

  By connecting a lid to the tip of the power take-out piston of the internal combustion engine of the present invention, there is an effect of slowing invasion of fine particles of ash and carbides in the liquid that transmits power and dissolved gas components.

  Since the liquid in the internal combustion engine of the present invention is circulated and the solid matter of ash and carbide is removed by the centrifugal separator, the circulating liquid can be cooled at that time.

  Since power generation using the internal combustion engine of the present invention generates power at a relatively low temperature, there is little nitrogen oxide in the exhaust gas, and the fuel is plant, so there is also little sulfur oxide. It is also suitable for relatively small-scale power generation, so it can be installed in the suburbs of the city, has little transmission loss, and low-temperature hot water can be used effectively for district heating.

  Embodiments of the internal combustion engine of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a mesh-like movable partition wall 2 is installed inside a cylinder 1, an ash and carbide layer 3 is formed thereon, and water 4 is filled under the mesh-like movable partition wall 2. The valve 6 in the intake pipe 5 is opened from the intake pipe 5 to inject a mixture of combustible powder and air into the explosion combustion space 7 in the cylinder 1.

  Then, the plurality of ignition devices 8 perform the explosion combustion evenly in the explosion combustion space 7. This exerts pressure on the water 4 through the ash and carbide layer 3 and the reticulated movable partition 2.

  This pressure propagates to the piston built-in cylinder 9 on the opposite side of the explosion combustion space 7 of the cylinder 1, pushes the piston 11 through the oil 10 in the piston built-in cylinder 9, and this motion becomes the rotational motion of the rotating body. Take it out.

  Next, since the piston 11 applies pressure to the oil 10 by the inertial rotation of the rotating body, the pressure pushes up the water 4 inside the cylinder 1, and the burned gas in the explosion combustion space 7 is discharged into the valve 13 in the exhaust pipe 12. And the exhaust pipe 12 is exhausted.

  Next, due to the inertial rotational movement of the rotating body, the piston 11 is pulled toward the outside of the cylinder 1, and a mixed gas of combustible powder and air is sucked into the explosion combustion space 7 from the intake pipe 5 in which the valve 6 is opened. .

  Then, by the inertial rotational movement of the rotating body, the water 4 is pushed by the piston 11 in the upper direction of the cylinder 1, thereby compressing the mixed gas of the heatable powder and air in the explosion combustion space 7. Ignite. By compressing and igniting, the explosion power is increased, the combustion efficiency is increased, and the generation of carbides is reduced.

  By repeating this operation, power is generated by converting the explosive force in the explosive combustion space 7 into the piston motion of the piston 11 and further the rotational motion of the rotating body.

  An ultrasonic device 14 is installed on the ceiling of the cylinder 1, the thickness of the ash and carbide layer 3 deposited on the mesh movable partition 2 is measured, and the size of the holes in the mesh movable partition 2 is adjusted. is doing. There is also a method of controlling by changing the generation amount of ash and carbide by changing the mixing ratio of combustible powder and air.

  The water 4 in the cylinder 1 is drained by a circulation pipe 15, ash and carbides are separated by a centrifuge 16 in the middle, and the water 4 in the cylinder 1 is circulated again by pouring into the cylinder 9 with a built-in piston. Ashes and carbides are taken out and the water 4 is cooled.

  The exhaust gas discharged from the exhaust pipe 12 is guided to the centrifuge 17. At this time, since the rotor blades 18 of the centrifugal separator 17 are blown at an angle, the rotor blades 18 are helped to rotate.

  The exhaust gas from which ash and carbides are continuously and efficiently removed by the centrifugal separator 17 warms the boiler and rotates the steam turbine with the steam to generate electricity.

  The exhaust gas that warms the boiler is blown again into the water to remove harmful components, and the warm water that is heated by blowing the exhaust gas together with the hot water cooled after turning the steam turbine is used for district heating. The For this reason, the thermal energy utilization efficiency of this combustible powder is extremely high. Ashes are reused for forestry and agriculture.

  A lid 18 is connected to the piston 11, and the oil 10 is sealed between the lid 18 and the piston 11, so that the lid 18 delays the progress of contamination of the oil 10.

  In the production of combustible powder, a hard part such as a plant trunk is made into a crushed powder with decaying fungi, and a soft part is ground and dried as it is to obtain a powder. The dry powder may be mixed with a little oil. Further, there is a method in which powder is mechanically produced and further crushed by adding water and reducing the pressure from high temperature and pressure at once.

  In order to intensify the explosion force and uniformly explode, there is a method of igniting by irradiating the explosion combustion space 7 with a laser beam or a strong pulsed light beam from a flash lamp from several places.

  There is an embodiment in which silicone oil is used instead of water 4.

  INDUSTRIAL APPLICATION This invention can be utilized for the thermal power generation using the combustible powder manufactured from the plant.
