Description
Technical field
The utility model belongs to employing with the power engine of hydrogen with relevant gas fuel combination, particularly hydrogen mixed gas fuels and energy machine.
Background technique
Traditional combustion power machine complicated in mechanical structure, mechanical engagement part precision prescribed height, lubrication system complexity.Combustion power machine whole control process is very complicated, and mechanical loss is big, and mechanical efficiency is low.And behind the use hydrogen fuel, pure hydrogen power engine output power is low, and optimization fuel and mixing can make control procedure more complicated, require higher, there is significant limitation in the hydrogen fuel power machine of research at present, occurs pre-ignition or abnormal combustion in the course of the work, causes power output lower or unstable, lack practicability, and be difficult to promote.
Summary of the invention
The purpose of this utility model is to provide a kind of hydrogen mixed gas fuels and energy machine, simplified mechanical structure, it is rational in infrastructure, and control procedure is fairly simple, fuel combustion is stable, can improve the conversion efficiency of energy, power output is stable, and hydrogen usage is few, the output power height, mechanical assembly is few, and is easy to maintenance, need not to adopt complicated lubrication system.
The purpose of this utility model is achieved in that a kind of hydrogen mixed gas fuels and energy machine, comprise the turbine rotor group, by casing, impeller shaft and impeller constitute, the uniform jet ingress of impeller outer peripheral surface is being provided with corresponding ejecting gun respectively in casing, the spray gun port of ejecting gun is corresponding with impeller blade, ejecting gun is by the master, the gentle conductance of subsidiary combustion chamber constitutes to gun barrel, hydrogen nozzle and igniter that the hydrogen suction tude connects are being set on the rear wall of axiolitic subsidiary combustion chamber, the front portion of subsidiary combustion chamber is connecting the longitudinal end inlet that inwall is axiolitic main combustion chamber by collapsible tube, the outlet of the main combustion chamber major axis the other end is connecting and is being camber line shape air-flow guiding gun barrel, guiding gun barrel end is being provided with spray gun port, the compressed-air atomizer that compressed air inlet pipe connects is being set on the outlet locular wall of main combustion chamber, the vaporization gas nozzle that high-temperature evaporation gas steam inlet pipe connects is being set on the locular wall of main combustion chamber.
The utility model is that the high-temperature high-pressure air flow that is sprayed by A gas injection lance promotes impeller rotation acting.Its working procedure is: earlier pressurized air is fed in the main combustion chamber, charging into the compressed-air actuated while to subsidiary combustion chamber, pressurized air also flows to the guiding gun barrel, after pressurized air impacts muzzle, spray into impeller blade and casing by mechanical seal and the formed static air pressure sealing of pressurized gas, form a complete relatively relative seal space, make the increased pressure of subsidiary combustion chamber, also in gun barrel, form the vent plug that density is very high simultaneously.This moment, hydrogen was sprayed into subsidiary combustion chamber, when ever-increasing hydrogen and pressurized air mix, lighted by igniter and produce detonation, mixed gas is in the process of subsidiary combustion chamber reaction, temperature and pressure is also constantly increasing, and spread to the muzzle direction, at this moment in main combustion chamber, spray into the water vapor of high-temperature evaporation, the water vapor that is in the thermolysis transition point is further vaporized by high temperature in main combustion chamber and is decomposited hydrogen and oxygen, further mix, burning, chemical reaction process repeatedly discharges higher temperature and pressure, and high-energy fluid impacts muzzle and promotes the impeller rotation.After impeller turns over a tooth phase angle when the second tooth position, just entered between the relative sealing merit of next acting, carrying out above-mentioned hydrogen and pressurized air mixes, igniter is lighted detonation, and high-temperature water vapor decomposes in main combustion chamber, mixes, the process of burning, the active force of detonation gas generation continuously continuously promotes follow-up blade continuously works impeller.Waste gas is discharged from relief opening, participates in the process of producing of high-temperature water vapor or enters steam generating system.Hydrogen is to split water into hydrogen and oxygen by hydrogen generator, sends in the different ejecting guns by distributor after the hydrogen pump pressurization through the hydrogen after cooling.High-temperature water vapor sprays into ejecting gun by high-pressure service pump pressurization back vaporization.
Key problem in technology of the present utility model is that mixed gas forms certain first pressing in sufficiently long gun barrel, ignite the source by very a spot of hydrogen as High Temperature High Pressure, and in a single day formed the vent plug of high pressure high density by supercharging repeatedly through reaction repeatedly, will produce bigger impulse force to load.Though appearances such as the chemical reaction that is taken place in ejecting gun approaches compression adds the adiabatic expansion process, but the rear end is because the length and the formed vent plug of pressurized air of gun barrel, the last ejecting gun outlet pressure of its process remains approximate isopiestic process, but right-about has taken place in its energy properties, this mainly is that pressurized air has not only produced mixing of first pressing and hydrogen, improved the burning energy of hydrogen, also reduce simultaneously the reacting dose and the rapid diffusion of hydrogen, the more important thing is the density that has increased mixed gas in the gun barrel.
The utility model has simplified mechanical structure, and it is rational in infrastructure, and control procedure is fairly simple, and fuel combustion is stable, improved the conversion efficiency of energy, power output is stable, and hydrogen usage is few, the output power height, mechanical assembly is few, and is easy to maintenance, need not to adopt complicated lubrication system.
