the high-temperature tail gas of the high speed of large flow is from the inner tube porous medium heat recovery heat retainer pipe (2) of the temperature end (12) of high-temperature tail gas supplying tube (1), in internal layer porous medium heat retainer (3) constantly very easily during passing through at a high speed, under the accumulation of heat effect of internal layer porous medium heat retainer (3) and the high heat absorption of outer porous medium heat retainer (8), a large amount of heat of high temperature of high-temperature tail gas self is by internal layer porous medium heat retainer (3), asking for of outer porous medium heat retainer (8) high speed absorbed heat rear and stores, high-temperature tail gas at a high speed is after constantly a large amount of heat releases, at last at inner tube porous medium heat recovery heat retainer pipe (2), discharge fast very easily in the low temperature residual air outlet pipe (4) of the low-temperature end (11) of internal layer porous medium heat retainer (3).the fresh Cryogenic air of large flow is from the air-strainer (6) of fresh Cryogenic air supplying tube (5), the outer tube porous medium heat recovery heat retainer pipe (7) of the low-temperature end (11) of standby secondary gas compressor (23), when constantly passing through fast very easily in outer porous medium heat retainer (8), high temperature in inner tube porous medium heat recovery heat retainer pipe (2) is by under a large amount of exothermic effects of the outer porous medium heat retainer (8) in internal layer porous medium heat retainer (3) and outer tube porous medium heat recovery heat retainer pipe (7), the fresh Cryogenic air of large flow is by internal layer porous medium heat retainer (3), constantly high speed preheating heat absorption of outer porous medium heat retainer (8), the fresh Cryogenic air of large flow is after constantly a large amount of preheating heat absorptions, transform into high temperature air from outer tube porous medium heat recovery heat retainer pipe (7), the high temperature air of the temperature end (12) of outer porous medium heat retainer (8) imports output very easily in engine charge supplying tube (10), enter in cylinder (18).This device busy after the long regular hour, can be under the acting in conjunction of high-temp combustion deashing electrical bar (13), electrical heating high-temperature combustion control device (14), power supply (15) deashing, after carrying out tail gas soot combustion cleaning regeneration, this device after the cleaning regeneration of tail gas cigarette ash high-temp combustion, again can be again brand-new input normal operation.Iterative cycles so constantly.
This device must be strengthened the working procedure that high-temp combustion purifies during to the disposal of pollutants of motor exhaust especially severe especially
The high-temperature tail gas of the high speed of large flow enters into the high high temperature that mixes from high-temperature tail gas supplying tube (1) and fires in electric heating low oxygen combustion chamber (24) again, meanwhile, high temperature combination gas in high temperature combustors (27) and high flame also enter into the high high temperature that mixes and fire in electric heating low oxygen combustion chamber (24) again, fire the more high temperature mixed combustion of carrying out further homogeneous under the obstruction of the purifying electric self-cleaning filter plate of heating (26) at cigarette ash high temperature again.when outer tube high-efficiency air cooling porous medium heat recovery heat retainer pipe (7), high temperature air in outer porous medium heat retainer (8) is by high temperature air input control system (30), high temperature combustion-supporting air supplying tube (29) enters in the high flame burner of self ignition high temperature (28), when high-energy fuel passes through high-energy fuel input control system (32), high-energy fuel input high-pressure injector (31) enters in the high flame burner of self ignition high temperature (28), high temperature air and high-energy fuel mixed at high speed and catching fire in the high flame burner of self ignition high temperature (28).When inflammable mixture and the high flame of high temperature ejects from the high flame burner of self ignition high temperature (28) inner high voltage, high temperature mixes the rear while of catching fire and enters at a high speed the high high temperature that mixes and fire and carry out further in electric heating low oxygen combustion chamber (24) more that the high mixed combustion of high temperature purifies in high temperature combustors (27).the effect that cigarette ash high temperature fires the purifying electric self-cleaning filter plate of heating (26) again is: stop cigarette ash and ultra micro small particle (high flame high temperature can be removed organic substance and superfine particulate matter), the effect of the high flame burner of self ignition high temperature (28) is: make high temperature air and high-energy fuel mixed at high speed and catch fire to generate high temperature combination gas (if accident occurs in the cold start-up automatic ignition when slower, can adopt igniter (25) to carry out high speed and light), the effect of high temperature combustors (27) is: double to strengthen the mixed combustion of the high flame burner of self ignition high temperature (28), high temperature air and high-energy fuel high temperature are mixed and the combination gas of high-temp combustion generation high temperature, the effect that high mixing high temperature fires electric heating low oxygen combustion chamber (24) again is: by electrical heating high-temperature combustion control device (14), the more combustion again of high temperature is carried out further in the effect of power supply (15) again, this secondary combustion makes high temperature combination gas and high-temperature tail gas carry out the High Temperature Rotating turbulent flow to mix and reach the required temperature of reaction, and make the tail gas waiting time therein of high temperature reach necessary requirement, simultaneously to the internal layer porous medium heat retainer (3) in inner tube porous medium heat recovery heat retainer pipe (2), the temperature end (12) of the outer porous medium heat retainer (8) in outer tube high-efficiency air cooling porous medium heat recovery heat retainer pipe (7) further doubles its tail gas combustion gas is burnt away until complete after-flame after pre-exothermic heat again, and the environmental requirement of tail gas after burning purifies that reach a high temperature.The recoverable working procedure of exhaust gas heat is the same.
The unconventional burning low emission of high temperature: Ultra Low-oxygen burns under normal conditions, and burning can not be carried out.But through after high temperature preheating, whole combustion space all is in very high high temperature due to air, conventional combustion only in the zone of combustion of flame temperature high, outside the zone of combustion, temperature is lower.High temperature can significantly be expanded flammable range, homogeneous combustion in volume.Make in the past that the centuries is considered to impossible thing, be achieved under the condition of high temperature.Although high temperature may cause generating too high nitrogen oxide, because oxygen concentration is lower, just be not easy to occur.For example, can be converted into inflammable gas at the high temperature condition carbon dioxide, so high-temperature and low-oxygen combustion is brand-new unconventional stable combustion phenomena.
