Economizing tail gas purifier for gasoline locomotive

The utility model is a kind of gasoline locomotive saving and tail gas purification device, is made up of magnetizer, tonifying Qi plate and filter screen.Belong to the air cleaner class, international classification number is: FO2M37/22.

The kind of gasoline locomotive oil-saving clarifier is a lot of at present, for example: the working principle of the purifier that has is to adopt the high heat in surface of the exhaust branch pipe that utilizes motor, be input in the air inlet disk after the fresh air preheating with cartridge heater inside, through handling, the gasoline mixture temperature that enters the Carburetor below is improved, and uniformity coefficient improves.Strengthen the atomization quality of fuel oil.Fuel mixture is burnt more fully.Thereby improve rate of combustion greatly to reach the equal fuel oil of joint, reduce the purpose of taking the gas discharging.This is monistic purifier.And for example: Chinese utility model patent 87208967 discloses the compound oil-saving clarifier of a kind of petrol engine.This purifier is made up of DJ type series magnetizer, aerofoil and mixing blade.It sets up the main aerofoil that uses for idling mode of using by fuel is magnetized processing, adjusts methods such as air output at any time, improves the rate of combustion of fuel.This device can make carbon monoxide content and the hydrocarbons content in the tail gas reduce, and reduces oil consumption.But, because the direct air inlet in air channel makes its noise very big; And, make the magnetic susceptibility reduction owing to circuit is easily broken because magnetizer uses is that electric field adds magnetic field.Thereby on using, be subjected to certain restriction.

The purpose of this utility model is to avoid deficiency of the prior art, and has proposed a kind of gasoline locomotive saving and tail gas purification device.This purifier has adopted tonifying Qi plate, filter screen and a homopolarity magnetizer of forming with two relative novel high-strength magnetic permanent-magnet steels of homopolarity.So both can abate the noise, and can further improve the fogging degree of fuel oil again, thereby reach the carbon monoxide that reduces in the tail gas and the content of hydrocarbon, and order has reduced oil consumption.

The purpose of this utility model is realized by following measure.The magnetizer matrix is a joint metal garden cylindrical shell, and correspondence is inlayed two block sizes and equated the magnet steel that obverse magnetic pole is identical on the wall in vivo.The surface of two magnet steel correspondences is parallel to each other.An air chamber is arranged, the spilehole that several air inlets of going to the bottom of air chamber are used on an end of tonifying Qi plate.Air several spileholes below air chamber enter air chamber.After entering air chamber, because air will be through the tubular filter screen that vertically is arranged on the passway and the passway is surrounded.The gas lid is withstood in the upper end of filter screen.Filter screen has played certain effect that abates the noise.The outlet of passage connects a circular groove, and air enters circular groove through passage again by behind the filter screen.Because the effect of circular groove, enter Carburetor after making air-flow generation jet phenomenon, making has a large amount of air in the Carburetor, can make fuel oil more fully with airborne combination with oxygen, thereby further improve atomization quality.

The purpose of this utility model can also be further perfect by following steps.

In purifier, the other end of the passage of tonifying Qi plate is laid one and can be regulated the adjustment screw of air inlet amount by rotation.By the invasion depth of turn adjustment screw, the air inflow of regulating air.The diameter of the air inlet aperture that air chamber is gone to the bottom is 3 millimeters, and quantity is 12.The diameter of passage is 5 millimeters.

The utility model compared with prior art has following advantage: at first the magnet steel structure arrangement of magnetizer is simple, reasonable.When fuel oil directly passes through air gap between these two high-strength, heatproofs, the corrosion-resistant magnet steel, because the effect in magnetic field distance increasing, viscosity between the fuel molecule are descended, thereby mist of oil attenuates, combine with airborne oxygen is better, cause the fuel-oil atmozation degree to improve greatly.In addition, after air enters air chamber by aperture, pass through filter screen, filter screen has played the effect of eliminating the noise and filtering.When air entered aperture, air was under pressure and is compressed, enter air chamber after because that area becomes suddenly is big, air is expanded, air is compressed again during through filter screen, expands again afterwards.Air through the process of overcompression and expansion, makes that variation has taken place the distance between the molecule continuously after having stood atmospheric pressure like this.Because retardance resistance and air friction effect between the air molecule can constantly rub.Heat exchange has consumed acoustic energy on the one hand, and has discharged the part heat on the other hand, thereby has improved the temperature of the fuel mixture body in the Carburetor.So the utility model compared with prior art has noise free, oil inflame is abundant, has reduced oil consumption, and has reduced the carbon monoxide in the tail gas and the advantages such as content of hydrocarbon.

The utility model has 3 width of cloth accompanying drawings, wherein:

Fig. 1, be the magnetizer structural representation in the utility model;

Fig. 2, be the gas supplementary structure schematic representation in the utility model, be combined into most preferred embodiment, also can explain the accompanying drawing of book extract with Fig. 1;

Fig. 3, be the worm's eye view of gas supplementary structure in the utility model.

The utility model will be further described embodiment in conjunction with the accompanying drawings:

Most preferred embodiment of the present utility model as shown in Figures 1 and 2, the magnet steel ［ 4 ］ on magnetizer matrix ［ 2 ］ is fixed thereon by magnet steel retainer ［ 1 ］, magnet steel ［ 18 ］ is embedded on the magnetizer matrix ［ 2 ］.Magnet steel retainer ［ 1 ］ one headband has rectangle groove, and the other end is the Luo post.It can be connected with magnetizer matrix ［ 2 ］ Luo line.Be lined with packing ring ［ 3 ］ during connection.Two ports of magnetizer matrix are with Luo and buckle, and can be connected with pipe joint respectively.Two blocks of magnet steel require size identical, and end face wants parallel and polarity is identical, and are high-strength, heatproof, corrosion resistant permanent magnet steel.In the time of between fuel oil is directly through two blocks of magnet steel, because the effect in magnetic field, and the distance between the fuel molecule is strengthened, and viscosity descends, and mist of oil attenuates, and more helps fully combining with airborne oxygen, improves the fogging degree of fuel oil.

On tonifying Qi plate ［ 9 ］ one ends, a little air chamber is arranged, air chamber 12 apertures of having gone to the bottom, the diameter of aperture is 3 millimeters.Gas lid ［ 13 ］ is thereon fastening above the air chamber by screw ［ 15 ］.Gas lid ［ 13 ］ middle part raises up.Gas lid ［ 13 ］ is again the square of filter screen ［ 14 ］.A gas channel ［ 17 ］ is arranged at the bottom of air chamber, round platform of projection around the passage, and diameter is identical with gas lid ［ 13 ］ middle part convex portion, and two convex portions are mainly used in fixedly filter screen ［ 14 ］.Filter screen ［ 14 ］ vertically surrounds cylindric.The diameter of passage is 5 millimeters.One end of passage is connected with adjustment screw ［ 11 ］ Luo line, by adjusting the invasion depth of screw, controls the size of air inflow.When the mixed gas of petrol engine was dense partially, suitably tonifying Qi can make the effluent concentration of idling carbon monoxide and hydrocarbon reduce.The air compensation that the degree (purification ratio) that reduces depends primarily on the suitable size of the degree of former machine mixed gas overrich and air compensation can make carbon monoxide and hydrocarbon that suitable reduction is all arranged, when the carbon monoxide emission thing reduces, cause the increase of hydrocarbon, illustrate that tonifying Qi is excessive.Another outlet of passage ［ 17 ］ is joined with a circular groove ［ 16 ］.Because the effect of circular groove, enter Carburetor after making air-flow generation jet phenomenon, making has a large amount of air in the Carburetor, can make fuel oil more fully with airborne combination with oxygen, thereby further improve atomization quality.

When air entered aperture, air was under pressure and is compressed, and after air enters air chamber, because area becomes greatly suddenly, air was expanded, and when air passed through filter screen, another was compressed, and expands once more afterwards.Air continuously through processes such as overcompression, expansions, makes that the distance between the air molecule changes after being subjected to atmospheric pressure like this.Because the drag effect between the molecule and the effect of air friction can constantly rub, and produce heat exchange.Heat exchange has consumed acoustic energy on the one hand, has played the effect that abates the noise, and has discharged the part heat on the other hand, thereby improved the temperature of the fuel mixture body of Carburetor.Like this, make that the utility model noise is little, the fuel oil combustion scratches fully, reduced oil consumption, and reduced the carbon monoxide in the tail gas and the content of hydrocarbon.
