Abstract
A non-resistance cleaner for the waste gas of IC engine features use of the electron curtain and ray curtain purifying technique to clean the said waste gas. Its advantages include high speed, and sustained and high efficiency.
Description
The present invention is the new technology of various internal-combustion engine institute exhaust gas discharged being carried out purified treatment, is particularly useful for the waste-gas cleaning of various diesel engine.Belong to the internal-combustion engines exhaust gas purifying technical field.
Internal-combustion engine is widely used as power source, but its exhaust gas discharged all contains pollutant, especially diesel engine, though have plurality of advantages such as horsepower is big, energy-conservation, safe, be widely used in the powerful places of needs such as power drags, load-carrying vehicle, ferry boat, but the waste gas that diesel engine ejects is not only black but also smelly, pollutes especially severe, ecotope on every side there is considerable influence, should thoroughly administers.But domestic and international existing internal combustion engine waste gas purifier mainly is to utilize rare metals such as platinum, rhodium, palladium as catalyzer, and plating is distributed in the porous carrier surface, forms the oxidation catalyst filter layer, the toxic substance in the purifying exhaust air.There are three major defects in existing purifier: 1. when waste gas during by this catalytic filter that mechanical barrier arranged, certain circulating resistance is arranged, when the micropore of ventilating in the purifier being diminished gradually along with the suspending particulate matter in the waste gas, the also corresponding rising of resistance, but the waste gas circulating resistance can make the decrease in efficiency of motor.2. when waste gas passed through this purifier, the suspending particulate matter in the waste gas can harm waste gas gradually and contact with the effective of catalyzer attached to catalyst surface, thereby purification efficiency is reduced gradually.3. average purification efficiency is not high, thus often need in the practicality to use with pre-process (before reducing the combustion that is produced as purpose of polluting, installing) measure match, and need the fuse (catalyzer) of periodic replacement purifier.Because there is above shortcoming in existing internal combustion engine waste gas purifier, so remain in actual applications, purify and be applied to pollute more serious diesel engine exhaust in certain trouble, certain difficulty is then more arranged.
The present invention uses new cleaning principle, a kind of mechanical barrier that do not have is provided, non-resistance and the internal combustion engine waste gas purifier of very high purification efficiency is arranged, for various internal-combustion engines, especially pollute all kinds of diesel engine of especially severe and make purifying exhaust air usefulness, can reduce the pollution of internal-combustion engine significantly atmosphere.
Whole purification process is to finish in the cylindrical metal container of a conduction.Three technological pointss are arranged: main points one. already present ion energy in the waste gas that will under High Temperature High Pressure, produce, discharge by a pretreatment chamber, it is become be electroneutral waste gas.When discharging the ion energy, collect and remove a part of suspending particulate matter in the waste gas; Main points two. make pretreated neutral waste gas, pass thick slightly electronics (or ion) curtain that constitutes in the space by DC electronic (or ion) stream, make all suspending particulate matters in the waste gas (comprising the liquid grain), all with going up electric charge of the same race.The carrying capacity that particulate matter particle diameter (rude classification) is big is big, and the carrying capacity that particle diameter is little is little, and various like this suspending particulate matters have all become big or small ion cluster.The big or small suspending particulate matter in the waste gas utilize the neutral object of ion pair that the principle of electric field force is arranged, so under the situation of circulation rapidly, still can be separated apace, and is collected and remove; Main points three. the waste gas that makes suspending particulate matter be eliminated, pass a ray curtain that constitutes in the space by any ray (comprising ultraviolet ray) again, or the high-velocity particles curtain that constitutes in the space by any high-velocity particles stream, make each atom in the toxic compounds gas molecule in the waste gas, because of being subjected to exciting of ray or high-velocity particles, make its some electronics that moves on different tracks, obtain energy and produce energy level transition, promptly the capacitation electronics jumps to top level from low level.Like this, under High Temperature High Pressure, rely on several toxic compounds gas molecules that outermost surface shared electron para-linkage is produced in each atom,, thereby bonding action is disintegrated because of each atom outermost electron number in its molecule is subjected to electron jump that the variation of moment takes place.That is to say, covalent bond in the toxic compounds molecule between each atom is destroyed, so toxic compounds is broken down into each nontoxic simple substance molecule (for example two nitrogen dioxide molecules are broken down into a nitrogen molecular and two oxygen molecules) at normal temperatures, or reformulates other non-toxic compounds at normal temperatures.Like this, handle by above three technological pointss, the toxic substance in the solid, liquid, gas three-phase in the waste gas has all obtained effective purification.Cylindrical metal container barrel for double as suspending particulate matter collecting board carries out online dedusting with mechanical scraping and brushing apparatus to it, to keep the long-term high-efficiency operation of purifier.
Embodiment of the present invention are example with truck with the catalytic converter of diesel engine, and accompanying drawings is as follows: accompanying drawing is the catalytic converter principle sketch of truck with diesel engine.The waste gas that ejects from engine exhaust pipe enters the waste gas pretreatment chamber 2 with cylindric space through suction port 1, has many through holes and waste gas buffer cell 3 to communicate on the cylindrical metal barrel of pretreatment chamber 2.Waste gas in pretreatment chamber, by with the contacting of neutral barrel and through hole, original ion can obtain to discharge, and makes waste gas be electroneutrality, a part is collected attached to the particulate matter on the barrel simultaneously.Buffer cell 3 has the space of ring-type, and its volume ratio pretreatment chamber 2 is big, play buffering pulsating nature of waste gas and conversion exhaust flow to effect.After waste gas entered buffer cell 3, the aperture that many rows make annular configuration through the left side sprayed into the 1st purifying chamber 4 again.The 5th, be enclosed within the dentation point discharge terminal on the axle, terminal 5 needs with metal cylinder good insulation performance is arranged, and directly to the barrel discharge, makes the annulus between terminal and the barrel all be full of electronic current and form electronics curtain 6.Discharge voltage is decided on the distance between terminal and the barrel, generally arrives between several ten thousand volts at several kilovolts, can be got by automobile-used 24 volts of dc voltage conversions, and positive and negative VDC all can be used.Spray into the waste gas of the 1st purifying chamber 4, bigger disturbance is arranged because of colliding mutually.So though waste gas does not pass the electronics curtain, suspending particulate matter wherein also can obtain a large amount of electric charges and by preliminary purification from the electronics curtain.After waste gas passed electronics curtain 6 and enters the 2nd purifying chamber 7 and purify, all suspending particulate matters in this moment waste gas removed only a few and sneak into the waste gas China and foreign countries again because of reentrainment of dust, all were separated and were collected on the metal barrel 8.The structure of discharge terminal 9 is identical with discharge terminal 5 with requirement, just discharge voltage will be brought up to the annulus that makes between terminal 9 and the barrel, (this example adopts high-velocity electrons (particle a kind of) stream all to be full of the near ultraviolet end visible light that can estimate significantly, can produce the visible light of ultraviolet ray and multiple frequency after atom is excited by high-velocity particles), form the high-velocity particles curtain.The waste gas that suspending particulate matter has been eliminated, when high-velocity particles curtain 10 passed in the 2nd purifying chamber 7, the toxic gas in the waste gas was decomposed.The 3rd purifying chamber 11 still can reduce reentrainment of dust.Clean air after the purification is arranged to atmosphere from relief opening 12.On the barrel 8, the bottom that the particulate matter of constantly being removed by mechanical scraping and brushing apparatus (not drawing on the accompanying drawing) is fallen barrel 8, and by the mobile thrust of waste gas, fall in the poly-dirt bag 14 at barrel breach 13 places.Poly-dirt bag 14 is gastight, and can load and unload easily, so that regularly empty dirt.
The non-resistance internal combustion engine waste gas purifier that is purified by electronics curtain and ray curtain has following advantage: 1. adopt electronics and ray to purify and have high purification speed and purification efficiency, can make dense black poisonous waste gas become colourless nontoxic clean air, test shows that its purification ratio can reach more than 97% to diesel-oil vehicle waste gas blackness.Since waste-gas cleaning and dedusting cleaning carry out automatically synchronously, so use for a long time can keep identical high purification efficiency constant.3. when waste gas vertically passes electronics curtain and ray curtain, there is not mechanical stop,, can not have a negative impact engine efficiency so almost do not have resistance during waste-gas cleaning.4. new purifier has without hindrance noise elimination function concurrently, can save the energy that resistance consumes in original silencing apparatus, and is favourable to the efficient that improves motor.5. normal running cost is low.Only need empty the dirt in the poly-dirt bag in long-term the use, poly-dirt bag can use repeatedly.
