Description
Technical field
The present invention relates to engine reduces the device of nitrogen oxides, more particularly to a kind of engine tail gas waste-heat is reclaimed and is used for
Reduce nitride devices and Application way.
Background technology
Environmental pollution is 21 century most one of severe challenge for facing of the whole world.As developing country maximum in the world,
The environmental problem that China faces is particularly severe.China has become energy-consuming state the biggest in the world at present, and economical quickly sends out
Exhibition makes China's oil demand increasing, petroleum import external dependence degree also more and more higher；And the development with social economy, sedan-chair
The products such as car become popular consumer goods, and China is the volume of production and marketing whole world first of automobile now, and becomes volume of production and marketing for years
Big country, the consumption to fossil resources are huge, and the pollutant of motor vehicle emission is huge, and environmental pollution is increasingly severe；Particularly nitrogen oxygen
The discharge of compound, can cause photochemical reaction, huge to human body damage, or even can cause life danger；Due to traffic such as automobiles
Class delivery vehicle, often in operating modes such as low speed, idling, engine charge pipe pressure is low, makes exhaust insufficient, in cylinder for engine
Residual gas is high, causes engine charging efficiency low, and due to being in rich mixture shape in the operating mode engine cylinder such as low speed, idling
State, in cylinder, fresh air is not enough, easily causes engine in-cylinder combustion to catch fire, burns insufficient, Combustion Cycle Variability rate greatly, produces
Raw nitrogen oxides also compares many.
Petrol engine often in operating modes such as moderate duty, high load capacities, as air throttle is in half-open, full-gear,
Now air input of engine by air is greatly increased, and supply amount of fuel increases, and engine in-cylinder combustion is more violent, and the heating power of release also increases
Plus, the ignition temperature in cylinder is greatly increased, and can so be conducive to a large amount of generations of nitrogen oxides, however, engine firing condition
Also deteriorate further, amount of fresh air is not enough, other pollutants are also greatly increased.For diesel engine, in high load capacity, cylinder internal combustion
Burn temperature to raise, required for fully burning more than fuel oil much larger than fresh air in 1, i.e. cylinder due to diesel engine excess air coefficient
Air capacity, and a large amount of generations of nitrogen oxides are high-temperature oxygen-enriched and the duration, therefore, diesel engine in big load, nitrogen oxygen
Compound discharge capacity is greatly increased.
Correlation technique, in order to reduce the discharge of engine, oriented engine is fed the steam that adds water in air flue by humidifier；
Also have directly to engine in-cylinder water injection, in engine compresses top dead centre, spray into water, absorbed heat by water, evaporate, reduce starting
Temperature in machine cylinder, lowers ignition temperature, and so as to reduce nitrogen oxides, idea is fine, but water is added in cylinder, if water yield mistake
Greatly, the water in engine cylinder does not have evaporating completely, the life-span on engine is produced impact, or even the things such as engine scuffing occurs
Therefore；Water does not evaporate completely, will enter in oil sump along Engine Cylinder Wall stream, dilutes machine oil, produces emulsion, oil lubricating
Once all parts engine oil pressure do not build up, the friction loss for making each part is increased, engine is reduced and is used the longevity
The problems such as life；Therefore, the control device of the addition of water, control logic are required for being accurately controlled, thus increase engine
The complexity of control, while a series of problems, such as increasing cylinder cap thermal stress and concentrate,
Content of the invention
For overcoming technical problem present in prior art, the present invention provides a kind of with variable pitch spiral nozzle device
Reduce the device of discharged nitrous oxides.
The technical scheme is that there is provided a kind of reduction discharged nitrous oxides with variable pitch spiral nozzle device
Device, including：Evaporimeter, water tank, evaporimeter intake pump, gas-liquid separator, variable pitch spiral nozzle device, gas-liquid separation

On the blast pipe, evaporimeter lower end is connected evaporator series with evaporimeter intake pump, evaporimeter intake pump and
Water tank is connected by pipeline, and evaporimeter upper end is connected with gas-liquid separator, and gas-liquid separator separates are with gas pressure stabilizing cavity by pipe
Road connects, and gas pressure stabilizing cavity is connected with gas pressurized pump by pipeline, and last gas is entered by variable pitch spiral nozzle device
Enter inlet manifold, air intake duct or cylinder.
The beneficial effects of the present invention is：With expanding economy, car, lorry consumption figure are greatly increased, engine
Reduction nitrogen oxides in exhaust emissions is also increasing；And with Abgasgesetz more and more stricter, the discharge control of nitrogen oxides
System is also further strict, and the present invention passes through into inlet manifold, air intake duct, cylinder, add vapor, the high temperature of in-cylinder combustion to steam water
Gas checking solution, produces hydroxyl and hydrogen-based, suppresses the generation of nitrogen oxidation, while also reducing ignition temperature, further reduces nitrogen oxides
Generation, energy-conserving and environment-protective are played the role of important.
