Description
Technical field
The invention provides a kind of diesel engine energy-saving and emission-reduction device, belong to the diesel engine energy-conserving and emission-cutting technology in the mechanical engineering field.
Technical background
Reducing oil consumption and reduce exhaust emission pollution, is the technical problem that is subjected to extensive concern in recent decades, and successively proposes several solutions.Wherein a kind of diesel oil emulsification machine technology is to adopt electric ultrasonic technique, and water is become the particulate of 0.5 micron of diameter, becomes water-in-oil with light diesel with mechanical agitation in the ratio of watering quantity 20-40%, is emulsus, the title diesel oil emulsification.The diesel oil emulsification fuel saving ratio reaches 5-8%, reduces exhaust emission about 10%.But this diesel oil emulsification is difficult for long term storage and long-distance transport, forms oil-water separation easily and can not use.
Also have a kind of fuel oil magnetizing technology, promptly by magnetic field magnetic line diesel oil molecules group is cut, diesel oil molecules group is diminished, and some help the abundant burning of diesel oil and realize fuel-economizing.But this fuel-saving technique oil-saving effect is also not obvious, does not have too big use value.
The third fuel-saving technique is to provide proper amount of water steam or water and ethanol mixed vapour or water and methyl alcohol mixed vapour to cylinder of internal combustion engine, and can reach the internal-combustion engine joint device technology of decomposing the after-combustion acting.This technology fuel-economizing is about 20%, and the exhaust pollutant discharge amount reduces.
Summary of the invention
At the deficiency of existing diesel energy-conserving and emission-cutting technology, the invention provides a kind of diesel engine energy-saving and emission-reduction device technology, promptly diesel engine is discharged an amount of waste gas with the atomized water spray processing of lowering the temperature, in cooling, make water smoke become water vapour, form waste gas water mixing steam.Utilize turbo charging installation and pipeline then, the air mixing after waste gas water mixing steam and the filtration is pressed in the cylinder of diesel engine suction tude.In the diesel engine working stroke, behind the chemical reactions such as main component carbon dioxide in the waste gas and water vapour generation decomposition, become the fuel of incendivity acting in the cylinder.Thereby significantly energy-saving and emission-reduction of diesel engine have been realized.
Concrete technical measures of the present invention are as follows:
Diesel engine energy-saving and emission-reduction device is by feed tank, water pump, adjusting control valve, water spray projector, atomizing tracheae, flow control valve, turbosupercharger, and therebetween, being connected by the pipeline order constitutes.Wherein, adjusting control valve is a three-way valve, and this valve is connected the outlet pipe and the reflow pipe of feed tank respectively, and water spray projector; The shower nozzle setting of water spray projector at one end is connected with the turbocharger air compressor air inlet pipeline, in the atomization conduit of the flow control valve that the other end and turbosupercharger outlet pipe branch road communicate; The purge conduits of air filter and mist pipe are connected with the compressor air inlet machine pipeline of turbosupercharger together; The gas compressor of the turbosupercharger output tube of calming the anger is connected the diesel engine intake pipe.
Its working procedure is as follows: from the waste gas that the turbosupercharger relief opening is discharged, by pipeline and flow control valve, draw an amount of waste gas.To this part waste gas with the atomized water processing of lowering the temperature.In to the waste gas cooling, spray water has become water vapour,, pressurize by turbo charged compressor air inlet machine pipe inspiration gas compressor by conduit waste gas water mixing steam through gas compressor, and filtered air, waste gas water mixing steam together is pressed in the diesel engine intake pipe.
In the diesel engine working stroke, when the temperature in the cylinder reached 1000 ° of left and right sides, the chemical reaction that carbon dioxide and water vapour take place respectively in the cylinder was:
1, carbon dioxide generation decomposition reaction generates carbon monoxide and oxygen.
2, the reaction of carbon dioxide and carbon generates carbon monoxide.
The chemical reaction that water vapour takes place is:
1, water vapour generation decomposition reaction generates hydrogen and oxygen.
2, the reaction of water vapour and oxygen generates hydroxyl.
3, water vapour and hydrogen ion reaction generation hydroxyl adds hydrogen.
4, water vapour and carbon water generation reaction coal gas.
This explanation, diesel exhaust are except that nitrogen, and its main component carbon dioxide and water vapour can become the fuel of incendivity acting in the cylinder of diesel engine by chemical reaction takes place.Accounting for waste gas always about 1% harmful gas carbon monoxide, hydrocarbon in addition, all is the direct fuel of work by combustion in the cylinder.
Because in compression stroke at the end, carbon dioxide and water vapour in the cylinder of diesel engine have been preheating to about 800 °, and in the diesel engine working stroke, when the temperature in the cylinder reached 1000 °, the heat of 1 kilogram of carbon dioxide absorption was 6.45 * 10
6* (1000-800)/1000=1.29 * 10
6Joule.0.85 the heat that the kg water steam absorbs is 1.14 * 10
7* (1000-800)/1000=2.28 * 10
6Joule.After 1 kilogram of diesel combustion acting, if about 1/3 of combustion gas is sprayed into 0.4 kilogram of cooling water smoke, form diesel exhaust water mixing steam and draw air return cylinder recirculation, the heat energy that can increase the diesel engine acting is: carbon dioxide decomposes the heat energy (6.45 * 10 that after-combustion discharges
6--1.29 * 10
6) add that the heat energy (1.14 * 10 that waits the reaction after-combustion to discharge takes place to decompose water vapour
7-2.28 * 10
6) be 1.428 * 10
7Joule.This heat is equivalent to the heat energy of 0.43 kilogram of diesel oil.
The theoretical fuel saving ratio of diesel engine energy-saving and emission-reduction device: 43%.
The characteristics of its fuel-economizing of diesel engine energy-saving and emission-reduction device are: improve along with diesel load increases fuel saving ratio.As large tractor car pusher-55, when using diesel engine energy-saving and emission-reduction device full load rotary tillage operation, fuel saving ratio reaches 35%, and fuel-economizing is not seen in zero load idle running, and the normal operation fuel saving ratio reaches 25% generally speaking, reduces discharging to reach 50%.
