Description

Technical Field

[0001] This invention relates to the field of steam engine technology, specifically to an explosive hydraulic power steam engine. Background Technology

[0002] Currently, common power output devices mainly include traditional steam engines, internal combustion engines, and expanders based on phase change expansion. Traditional steam engines heat water in a boiler to generate high-pressure steam, which drives a piston or turbine to perform work. Their heat source and power-generating components are separate, and their structure is relatively mature. Internal combustion engines generate high-temperature, high-pressure gas through the combustion of fuel in the cylinder, which drives the piston. They are characterized by rapid start-up and high power density. Stirling engines use an external heat source to heat the sealed working fluid, utilizing the gas's thermal expansion and cooling contraction cycles for stable operation, but their sealing structure is complex. In addition, some existing technologies also use low-boiling-point liquids as working fluids, heating them to boil and vaporize them to perform work, or using high-boiling-point liquids as heat transfer media to indirectly heat low-boiling-point liquids in order to achieve higher pressure output.

[0003] However, the existing solutions described above still have the following areas for improvement in practical applications: First, in the synergistic work-generating scheme utilizing the heat transfer of high-boiling-point liquids and the phase change expansion of low-boiling-point liquids, the lack of an effective limiting mechanism for the piston position and the high-boiling-point liquid surface in the cylinder before startup easily leads to poor nozzle-liquid surface contact, preventing the low-boiling-point liquid from boiling instantly and uniformly upon injection, thus affecting startup reliability. Second, the heat recovery stage after steam discharge is often separated from the condensation stage, and the high-boiling-point liquid after heat recovery requires additional pumping equipment to return to the cylinder for circulation, increasing system complexity and energy consumption. Third, the active stroke control of the piston in the existing device is relatively limited. During shutdown or startup, the piston position is random, and the liquid volume in the cylinder is not fixed, which is not conducive to achieving accurate injection-expansion-exhaust cycle control, thereby affecting the stability and adjustment range of power output.

[0004] To address this, we developed a new type of explosive hydraulic power steam engine. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an explosive hydraulic power steam engine that solves the problems of poor start-up reliability, high system complexity and energy consumption, and limited power output stability and adjustment range caused by deficiencies in existing start-up positioning, heat recovery cycle, and piston stroke control.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an explosive hydraulic power steam engine, comprising a combustion chamber, wherein an L-shaped cylinder is fixedly connected to the top of the combustion chamber, a low-boiling-point liquid inlet pipe extending into the interior is fixedly connected to the top of the L-shaped cylinder, and a nozzle is fixedly connected to the bottom of the low-boiling-point liquid inlet pipe. The top and sidewalls of the L-shaped cylinder are equipped with heat exchange components. A liquid filling pipe is fixedly connected to one side of the outer wall of the L-shaped cylinder. A drain pipe is fixedly connected to one side of the bottom of the L-shaped cylinder; A piston is slidably sealed on the inner wall of the L-shaped cylinder. A connecting rod is rotatably connected to the inner walls of both sides of the piston. A flywheel is rotatably connected to one end of the connecting rod located in the L-shaped cylinder. An electric limit assembly is installed on the input shaft of the flywheel.

[0007] Preferably, the heat exchange assembly includes a first solenoid valve, which is fixedly connected to the top of the L-shaped cylinder. The top of the first solenoid valve is fixedly connected to an exhaust pipe, one end of which is fixedly connected to a heat exchanger. The cold medium outlet of the heat exchanger is fixedly connected to a high-boiling-point liquid outlet pipe, which is fixedly connected to one side of the outer wall of the L-shaped cylinder.

[0008] The above technical solution enables the steam generated by the explosion to be introduced into a heat exchanger through the exhaust pipe for waste heat recovery.

[0009] Preferably, the liquid filling fitting includes a second solenoid valve, which is fixedly connected to the outer wall of one side of the L-shaped cylinder, and the other port of the second solenoid valve is fixedly connected to a high-boiling-point liquid adding pipe.

[0010] The above technical solution allows for the control of the opening and closing of the second solenoid valve, which facilitates the replenishment of high-boiling-point liquid into the L-shaped cylinder, ensuring that the liquid level in the cylinder meets the requirements for continuous operation.

[0011] Preferably, the drain pipe includes a third solenoid valve, which is fixedly connected to the bottom of the L-shaped cylinder, and the bottom interface of the third solenoid valve is fixedly connected to a high-boiling-point liquid drain pipe.

[0012] With the above technical solution, when it is necessary to replace or discharge high-boiling-point liquid, simply open the third solenoid valve to use gravity or pressure to completely discharge the liquid from the bottom of the cylinder through the high-boiling-point liquid discharge pipe, which is convenient for maintenance and working fluid replacement.

[0013] Preferably, the electric limiting component includes a bearing housing, and the inner ring of the bearing housing is fixedly sleeved on the mounting shaft of the flywheel. A limiting motor is fixedly connected to one side of the outer surface of the bearing housing, and the drive shaft of the limiting motor is fixedly connected to the mounting shaft of the flywheel.

[0014] Through the above technical solution, the limit motor can actively drive the flywheel and drive the piston to accurately stop at the preset position. Beneficial effects

[0015] This invention provides an explosive hydraulic power steam engine. It has the following beneficial effects: This explosive hydraulic power steam engine, by setting an electric limit component, can precisely limit the piston to the position where the nozzle is in contact with the surface of the high-boiling-point liquid before starting, ensuring that the low-boiling-point liquid boils instantly and uniformly when injected, effectively solving the problem of poor start-up reliability.

[0016] This explosive hydraulic power steam engine recovers and condenses the waste heat of the discharged steam through heat exchange components installed on the top and side walls of the L-shaped cylinder. At the same time, the heated high-boiling-point liquid is directly returned to the L-shaped cylinder for recycling, eliminating the need for additional pumping equipment and significantly reducing system complexity and energy consumption.

[0017] This explosive hydraulic power steam engine utilizes an electric limit assembly to actively limit the flywheel input shaft, precisely controlling the piston position during shutdown or startup to maintain stable liquid volume within the cylinder. This enables accurate cyclic control of liquid injection, expansion, and steam exhaust, thereby improving the stability and adjustment range of power output. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-4As shown, this embodiment of the invention provides an explosive hydraulic power steam engine, including a combustion chamber 1. An L-shaped cylinder 6 is fixedly connected to the top of the combustion chamber 1. The combustion chamber 1 is made of high-temperature resistant stainless steel (such as 310S) or high-strength cast iron, and a fire-resistant heat insulation layer can be provided on the inner wall. Its function is to generate heat through fuel combustion or electric heating, and to uniformly transfer the heat to the high-boiling-point liquid inside the L-shaped cylinder 6, so that its temperature rises to the set working range.

[0022] The top of the L-shaped cylinder 6 is fixedly connected to a low-boiling-point liquid inlet pipe 10 that extends into the interior. The bottom of the low-boiling-point liquid inlet pipe 10 is fixedly connected to a nozzle 16. The nozzle 16 is made of brass or stainless steel (such as 316L) and has a microporous or swirling atomization structure inside.

[0023] A heat exchange assembly is installed on the top and side wall of the L-shaped cylinder 6. The heat exchange assembly includes a first solenoid valve 9, which is fixedly connected to the top of the L-shaped cylinder 6. A steam exhaust pipe 15 is fixedly connected to the top of the first solenoid valve 9. A heat exchanger 7 is fixedly connected to one end of the steam exhaust pipe 15. A high-boiling-point liquid outlet pipe 8 is fixedly connected to the cold medium outlet of the heat exchanger 7. The high-boiling-point liquid outlet pipe 8 is fixedly connected to one side outer wall of the L-shaped cylinder 6. The cold medium inlet of the heat exchanger 7 is fixedly connected to an external high-boiling-point liquid supply pipe. The heat exchanger outlet of the heat exchanger 7 is fixedly connected to an external low-boiling-point liquid recovery pipe.

[0024] A liquid filling pipe is fixedly connected to one side of the outer wall of the L-shaped cylinder 6. The liquid filling pipe includes a second solenoid valve 14, which is fixedly connected to one side of the outer wall of the L-shaped cylinder 6. A high-boiling-point liquid adding pipe 11 is fixedly connected to the other port of the second solenoid valve 14.

[0025] A drain pipe is fixedly connected to one side of the bottom of the L-shaped cylinder 6. The drain pipe includes a third solenoid valve 12, which is fixedly connected to the bottom of the L-shaped cylinder 6. A high-boiling-point liquid discharge pipe 13 is fixedly connected to the bottom interface of the third solenoid valve 12.

[0026] The inner wall of the L-shaped cylinder 6 is sealed with a piston 5 that slides. The inner walls of both sides of the piston 5 are rotatably connected to a connecting rod 17. The connecting rod 17 is rotatably connected to a flywheel 4 at one end of the L-shaped cylinder 6. An electric limit assembly is installed on the input shaft of the flywheel 4. The electric limit assembly includes a bearing housing 3, and the inner ring of the bearing housing 3 is fixedly sleeved on the mounting shaft of the flywheel 4. A limit motor 2 is fixedly connected to one side of the outer surface of the bearing housing 3, and the drive shaft of the limit motor 2 is fixedly connected to the mounting shaft of the flywheel 4. The piston 5 is made of heat-resistant ductile iron or aluminum alloy, and has 2-3 piston ring grooves machined on its outer circumference. A combined sealing ring (steel ring + graphite filling ring) is installed. The limit motor 2 is an AC servo motor or a stepper motor, with a rated torque that matches the inertia of the flywheel 4. A brake may be installed at the tail of the motor.

[0027] When in use, an existing controller needs to be installed. The controller is electrically connected to the limit motor 2, the first solenoid valve 9, the second solenoid valve 14, and the third solenoid valve 12 to facilitate the overall control of the operation.

[0028] Working principle: Before startup, the limit motor 2 drives the mounting shaft of the flywheel 4 to rotate via the bearing seat 3. The flywheel 4 drives the piston 5 to move within the L-shaped cylinder 6 via the connecting rod 17, limiting the piston 5 to a specific position. Subsequently, the second solenoid valve 14 is opened, and high-boiling-point liquid is injected into the L-shaped cylinder 6 through the high-boiling-point liquid addition pipe 11 to the set liquid level. The second solenoid valve 14 is then closed. Simultaneously, the combustion chamber 1 starts working, heating the cavity within the L-shaped cylinder 6, causing the temperature of the high-boiling-point liquid to rise to a range higher than the boiling point of the low-boiling-point liquid but lower than its own boiling point.

[0029] When the temperature reaches the set value, the low-boiling-point liquid is injected into the high-boiling-point liquid through the low-boiling-point liquid inlet pipe 10 and nozzle 16. The low-boiling-point liquid instantly boils and vaporizes, its volume expands rapidly, and high-pressure steam is generated. The steam pressure drives the piston 5 to move linearly within the L-shaped cylinder 6. The piston 5 transmits power to the flywheel 4 through the connecting rod 17, driving the flywheel 4 to rotate and output mechanical energy.

[0030] The flywheel 4 continues to rotate due to inertia, pushing the piston 5 back through the connecting rod 17, while simultaneously pushing the high-temperature, high-boiling-point liquid in the L-shaped cylinder 6 towards the exhaust port. At this time, the first solenoid valve 9 opens, and steam enters the heat exchanger 7 through the exhaust pipe 15. In the heat exchanger 7, it exchanges heat with the cold medium, and the steam condenses into a low-boiling-point liquid (which can be recycled and reused). The high-boiling-point liquid after heat exchange flows back to the L-shaped cylinder 6 through the high-boiling-point liquid outlet pipe 8, realizing heat recovery and circulation.

[0031] When the system needs to replace or discharge high-boiling-point liquids, the third solenoid valve 12 is opened, and the high-boiling-point liquid is discharged through the high-boiling-point liquid discharge pipe 13. During the cycle, by controlling the opening and closing sequence of the first solenoid valve 9, the second solenoid valve 14, and the third solenoid valve 12, as well as the auxiliary positioning of the piston 5 by the limit motor 2, continuous and stable explosive hydraulic power output can be achieved.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
