Background technique
At present, the known method of energy in the internal-combustion engine combustion gas of utilizing is for installing runoff, mixed flow or axial flow turbine additional in the engine exhaust gas outlet, the internal-combustion engine combustion gas promotes the exhaust turbine rotation, and exhaust gas turbine drives the compressor turbine rotation, improves the cylinder of internal-combustion engine suction pressure with compressor turbine.This is the method for kinetic energy in a kind of indirect utilization engine exhaust gas, the energy utilized rate about 6% in the waste gas, very effective to improving internal combustion unit per unit volume working power (power/liter), but to the effect that improves internal combustion unit effective thermal efficiency is not very big, increases in addition in addition that compressor turbine and casing equipment, internal combustion engine compression terminal pressure are too high easily, petrol engine supercharging difficulty, compressor turbine speed of response wait problem slowly; Application number is that 2004100359523 patent of invention discloses the internal combustion unit that a kind of internal-combustion engine-exhaust gas turbine is united acting, the unit efficiency of this scheme is than the efficient height of internal-combustion engine-exhaust gas turbocharger group in theory, existing questions is that existing runoff, mixed flow or exhaust gas turbine with axial flow all are to design by high speed rotating, the rotating ratio of exhaust gas turbine is lower after exhaust gas turbine and internal-combustion engine are united acting, exhaust gas turbine produces bigger flow resistance to combustion gas, may influence the internal-combustion engine proper functioning; Surge appearred in turbine itself easily when runoff or mixed-flow exhaust gas turbine rotating speed were low.
Summary of the invention
The big deficiency of fluid flow dynamic resistance when having exhaust gas turbine low speed now in existing internal-combustion engines exhaust turbine supercharging technology and the disclosed technology of 2004100359523 patent of invention in order to overcome, more make full use of the kinetic energy in the engine exhaust gas, the present invention proposes with being fit to utilize kinetic energy in the engine exhaust gas than runoff, mixed flow or the exhaust gas turbine with axial flow of slow-speed of revolution operation or axial flow wind-force impeller
Technological scheme.
The technical solution adopted for the present invention to solve the technical problems is:
For runoff or mixed-flow exhaust gas turbine, existing runoff or mixed-flow exhaust gas turbine utilize that the efficient of kinetic energy is about 0.78 in the waste gas, it is generally all smaller to enter the waste gas outlet of turbine blade from volute on exhaust turbine, when the exhaust gas turbine stall, the exhaust gas turbine blade is blocked waste gas outlet basically; When the exhaust gas turbine rotating speed was low, the exhaust gas turbine blade was also bigger to the exhaust-gas flow resistance.In order to address this problem, a circle can be opened several waste gas outlets more on volute, make waste gas spray the impulse turbine blades from a plurality of outlets, even reach when the turbine stall, internal-combustion engine institute combustion gas also can enter turbine final vacuum runner swimmingly from the space between each turbine blade, reduce turbine stall or the rotating speed flow resistance to waste gas when low; Waste gas is from a plurality of outlets ejection impulse turbine blades, and the turbine blade force rate that is hit is more even, may help improving the surge problem of turbine blade.
For exhaust gas turbine with axial flow, existing exhaust gas turbine with axial flow surge can not occur in the slow-speed of revolution very to several 3 thousand commentaries on classics/min rotating speeds, exhaust gas turbine utilizes the efficient of waste gas kinetic energy to be about 0.77, turbine blade is a lot of and arrange very closely, may produce big flow resistance to waste gas when turbine stall or rotating speed are very low.But waste gas is to flow into turbine blade from whole thick grate flow channel, the cross section of fluid channel of inflow turbine blade is long-pending can be fully big, if the angle between turbine blade and turbine axis is much smaller than 90 °, space between exhaust gas turbine two blades is just bigger, even when the exhaust gas turbine stall, waste gas is still than being easier to pass through turbine blade, the exhaust gas turbine with axial flow blade is little to the flow resistance that waste gas causes, the flow resistance that the flow resistance that the exhaust gas turbine with axial flow blade causes waste gas in actual the use causes waste gas less than silencing apparatus.
For the axial flow wind-force impeller, axial flow wind blade blade profile is simple, blade quantity is few, and a general impeller is 3～4 blades, and blade impeller processing is simple far beyond runoff or axial-flow turbine, and cost is low far beyond runoff or axial-flow turbine; The axial flow wind-force impeller to several thousand/min rotating speed, surge can not occur in the slow-speed of revolution very; According to axial flow wind energy conversion system theory and laboratory data, first grade axis streaming wind-force impeller utilizes the efficient of waste gas kinetic energy to be about 45%, flows through also to contain 55% the kinetic energy of having an appointment in the waste gas of the 1st grade of axial flow wind-force impeller and be not utilized; Behind the 1st grade of axial flow wind-force impeller, can increase the axial flow wind-force impeller of the 2nd grade of coaxial rotation, flow through and also contain 30% the kinetic energy of having an appointment in the waste gas of the 2nd grade of axial flow wind-force impeller and be not utilized; Behind the 2nd grade of axial flow wind-force impeller, can increase the 3rd level axial flow wind-force impeller of coaxial rotation, flow through and also contain 16.7% the kinetic energy of having an appointment in the waste gas of 3rd level axial flow wind-force impeller and be not utilized; As seen through 3 grades of axial flow wind-force impellers, the utilization ratio of kinetic energy in the waste gas has been utilized the efficient of kinetic energy in the waste gas above one-level runoff, mixed flow or axial-flow turbine.Behind 3rd level axial flow wind-force impeller, can increase by multistage axial flow formula wind-force impeller such as the 4th, the 5th, further improve the efficient that wind-force impeller utilizes kinetic energy in the waste gas.After exhaust flow is through the axial flow wind-force impeller, radially outward and the circumferential component opposite with the wheel rotation direction have appearred in the speed of emission molecule, the radially outward velocity component becomes inside component through the runner inner wall reflection, impeller is rotated in the forward favourable, and circumferentially the velocity component opposite with the wheel rotation direction impeller is rotated in the forward unfavorable; In order to overcome in the steam molecule circumferentially and the velocity component of wind-force impeller direction of rotation, can on the runner inner wall between the wind-force impeller, install the velocity correction stator blade that is similar to the steam turbine stator blade additional, make emission molecule produce the velocity component identical, help the next stage wind-force impeller and utilize kinetic energy in the waste gas with the wind-force impeller sense of rotation.Axial flow wind-force impeller upper blade seldom, with on the one-level impeller between two blades from must be far away, even the wind-force impeller stall, waste gas also passes through from space between the blade easily; Behind the waste gas process one-level wind turbine impeller, flow direction can change to some extent, next stage wind turbine impeller blade should stagger than the blade of previous stage a bit, make when the wind-force impeller stall, the past grade blade flows through the waste gas that comes just in time can be passed through from the space between the grade blade of back, reduces the flow resistance that waste gas is produced as far as possible.After adopting multistage axial flow formula wind-force impeller, the volume of internal-combustion engine-wind-force unit can be bigger than the volume of internal-combustion engine-single-stage exhaust gas turbine unit, but a lot of large combustion units are fixing uses, as peculiar to vessel, generating with, drilling well with diesel engine unit etc. and do not require that unit volume is very little, so this method relatively is applicable to the internal combustion unit of fixedly use occasion.
When the radial-flow type in being contained in the waste gas runner, mixed-flow, axial-flow turbine or axial flow wind-force impeller low-speed running, after internal-combustion engine proper functioning problem and turbine, wind-force impeller self surge problem all solve, the rotating shaft and the I. C. engine crankshaft of exhaust gas turbine or waste gas wind-force impeller can be passed through gear engagement, exhaust gas turbine or waste gas wind-force impeller and externally acting of internal-combustion engine associating; Or the rotating shaft and the coaxial associating of I. C. engine crankshaft of exhaust gas turbine, waste gas wind-force impeller externally done work; Also can make the independent respectively externally acting of exhaust gas turbine, waste gas wind-force impeller.For large-scale diesel engine, relatively be suitable for and adopt multistage axial flow formula wind-force impeller, multistage wind-force impeller can externally do work separately, also can externally do work with the diesel engine associating; For medium and small-scale diesel engine, petrol engine, so class diesel engine, petrol engine be mainly used in mobile purposes such as vehicle, should adopt single-stage runoff, mixed flow or axial-flow turbine, turbine should with diesel engine, petrol engine associating output power; Also can make the axle of multistage waste gas wind-force impeller perpendicular with small diesel engine or gasoline engine crank, the axle of waste gas wind-force impeller meshes with helical gear or umbrella gear with the bent axle of small diesel engine or petrol engine; If multistage waste gas wind-force impeller volume is excessive, can reduce impeller progression, also can make the volume of unit integral body less.
Adopting the advantage of exhaust gas turbocharge is that the identical internal-combustion engine of volume of cylinder can produce higher power.If it is more high-power that hope obtains with the identical internal-combustion engine of volume of cylinder, still can adopt exhaust-gas turbocharger to the internal-combustion engine air intake pressurized, behind exhaust gas turbine, increase wind-force impeller in the runner again and recycle remaining kinetic energy in the waste gas.If not the energy that contains in the boosting internal combustion engine combustion gas accounts for 1/3 of fuel total energy, wherein the kinetic energy in the waste gas accounts for 60% of total energy in the waste gas, accounts for 18% of fuel total energy; Exhaust gas turbocharger group exhaust energy utilization ratio is 6% of an exhaust total energy, the kinetic energy that is contained from the waste gas that exhaust gas turbine flows out accounts for 54% of internal-combustion engine combustion gas total energy, if behind turbine, increase force 3 wind power impeller in the runner again, can reclaim again from exhaust gas turbine and flow out 83% of kinetic energy the waste gas, consider that pulse exhaust energy transmission efficiency is 68%, the total efficiency that internal-combustion engine-exhaust gas turbocharge-waste gas wind-force impeller is united the unit that does work can reach more than 42%.Behind large-scale turbine, in the waste gas runner silencing apparatus is housed, according to the technician introduce silencing apparatus to the flow resistance of waste gas greater than the flow resistance of axial-flow turbine to waste gas, with the waste gas wind-force impeller replace behind the silencing apparatus unit to the exhaust-gas flow drag overall when silencing apparatus is arranged unit to the exhaust-gas flow drag overall.This method is suitable for existing exhaust gas turbocharger group transformation is increased total output power very much.
Obtain more high-power if wish with the internal-combustion engine of same cylinder volume, still need adopt exhaust-gas turbocharger to the internal-combustion engine air intake pressurized, can behind exhaust gas turbine, increase wind-force impeller in the runner again and recycle remaining kinetic energy in the waste gas, wind-force impeller and exhaust gas turbine is coaxial, and make the waste gas wind-force impeller identical to the driving direction of their common axles with exhaust gas turbine.This method also is suitable for existing exhaust gas turbocharger group transformation is obtained higher output power very much.
The invention has the beneficial effects as follows:
The multiple way of utilizing kinetic energy in the engine exhaust gas can be arranged, can make full use of the kinetic energy in the engine exhaust gas, improve the turbosupercharger speed of response, simplify the structure of medium and small unit, improve unit efficiency; Be convenient to the transformation of existing large-scale diesel engine-exhaust gas turbocharger group, raise the efficiency.
