Description

Tail gas cleaner for motor-driven vehicle

The utility model belongs to a kind of new design of motor-vehicle tail-gas purifying device, is specially adapted to use the motor-driven vehicle gas disposal of petrol and diesel oil.

The pollution of motor vehicle tail gas has become the public hazards of present maximum.City particularly, the pollution of air mainly come from vehicle exhaust and are generally acknowledged.Thereby, the improvement of vehicle exhaust has been caused the attention of society.Particularly present, a large amount of diesel-oil vehicles have become the main force of transport service along with automobile and highway development.And exhaust gas from diesel vehicle contains black smoke, dust in a large number the people is extremely had a headache.Though at present a large amount of exhaust purifiers newly design appearance, the black smog of effectively administering in the tail gas, particularly exhaust gas from diesel vehicle does not have comparatively desirable scheme.

Goal of the invention of the present utility model is to design a kind of new tail gas cleaner for motor-driven vehicle, particularly utilizes liquid purifying media to remove residual solid particle in the tail gas, to reach the effect of eliminating black smoke.

Can tackle effectively when the machine oil of the gas tail gas that contains a large amount of unburned hydrocarbons by having certain stickiness, this fact is the rationale of the utility model designing institute dependence just.Concrete design is that one of design purifies the chamber, in purifying the chamber device that can produce oil curtain is set, and promptly produces the machine oil heavy curtain that a continuous machine oil is formed, and will purify chamber suction port of design then and link to each other with the outlet pipe of vehicle motor.Tail gas is entered purify behind the chamber with the chamber in oily heavy curtain fully contact, thereby with the impurity in the vehicle exhaust and the interception of residual carbon hydrogen compound in oil and reach purifying effect.Design a relief opening again and link to each other with tailpipe in purifying the chamber, and be provided with filter in exhaust ports, its purpose is to tackle the machine oil that flies to escape with cleaning of off-gas, with recycling, and prevents the secondary pollution that machine oil is overflowed and produced with tail gas.Because engine oil viscosity is big, the residual grain of interception solid is effective, and often produces fairly obvious purifying effect, and then purifying effect will be more obvious for diesel-oil vehicle especially.

How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of oily impeller.

Fig. 3 is that the A-A of Fig. 2 is to sectional view.

Fig. 4 is a front view of regulating wing plate.

Wherein 1 representative purifies the chamber, and the 1A representative purifies the suction port in chamber, and 1B represents relief opening, 1C represents suction chamber, and 1D represents the oil curtain chamber, and 1E represents the dividing plate between suction chamber and the oil curtain chamber, 1F represents gas passing plate, wing plate is regulated in the 1G representative, and 1H represents rotatingshaft, and the 2nd, total sequence number of oil curtain generating apparatus, 2A represents oily impeller, 2B represents oil nozzle, and 2C represents transport pipe, connects from the vacuum gear oil pump.2D represents return tube, and it is connected between oil return shell P and the oil filter 2E, delivers to the vacuum gear oil pump again from the machine oil that oil filter 2E comes out.Among the oil impeller 2A, 2A1 represents impeller shaft, and 2A2 represents the bearing on the impeller shaft 2A1.The 2A3 representative presses solidly the end cap of bearing 2A2, and 2A4 is the impeller frame, comes support blade by it, and 2A5 is a blade.The 5th, filter, 5A are pore, and 5B is the twine of the unordered setting in the filter 5.The 6th, Returnning spring.The 7th, tailpipe, the 8th, limiting block.

From the designed as can be seen purification chamber 1 of accompanying drawing 1 is the cuboid shape cavity that a cross section is a rectangle, and front end is provided with suction port 1A waste pipe and is communicated with, and the front end that purifies the chamber at suction port 1A place is provided with a suction chamber 1C and oil curtain chamber 1D.Suction chamber 1C and oil curtain chamber 1D are provided with and two spaces of intercommunication independently of one another.The centre is provided with dividing plate 1E.Dividing plate is provided with the spring gas passing plate 1F on through hole and the hole, and gas passing plate 1F is provided with rotatingshaft 1H and Returnning spring and its structural similarity orientation under the 1D of oil curtain chamber and also is provided with an adjusting wing plate 1G, also has rotatingshaft 1H and reset spring 6.Motor exhaust enters oil curtain chamber 1D for 1 time by inlet plate, enters the purification chamber by regulating wing plate 1F again.Automatically regulate the subtended angle of two gas plates along with the pressure of engine exhaust, to regulate vapour lock, generation fully contacts with oil curtain.Regulate the structure of wing plate 1F and see Fig. 4-Fig. 6, its purpose that flank is set is to prevent that tail gas from escaping without oil curtain, inlet plate 1F and regulate wing plate 1F and be contained on the locular wall by rotatingshaft 1H, the Returnning spring 6 on the rotatingshaft can produce automatically reset restoring force and finish the adjusting of air inflow size along with suction pressure.

Oil curtain generating apparatus 2 is key Design points of the present utility model.Oil curtain should generate machine oil heavy curtain evenly and continuously, and can fully contact with tail gas.Oil curtain generating apparatus of the present utility model is by oily impeller 2A, and oil injection nozzle 2B, transport pipe 2C, return tube 2D, oil filter 2E and vacuum gear oil pump (omitting in the accompanying drawing) are formed.Oil impeller 2A is arranged among the 1D of oil curtain chamber, above adjusting wing plate 1G.Oil nozzle 2B aims at the right angle corner place of blade 2A5.Return tube is connected between oil return shell and the oil filter 2E and passes to oil pump.Oil pump is connected with motor by belt pulley, obtains power, finishes the circulation of machine oil and carries.Machine oil from oil pump is sprayed on the blade by oil nozzle 2B, making oily impeller 2A produce high speed rotating scatters the circular covering of the fan of the machine oil that carries on the blade 2A5, form the oil curtain of the whole adjusting wing plate of envelope 1G superjacent air space, purify chamber 1 thereby the tail gas that enters air chamber is entered after by uniform contact.

The concrete structure of the oily impeller that Fig. 2 and Fig. 3 provide.It by impeller shaft 2A1, be enclosed within bearing 2A2, bearing (ball) cover 2A3 on the 2A1, be enclosed within the circular impeller frame 2A4 on the bearing outer ring and be fixed on two blade 2A5 between the leaf frame and form.Oil impeller 2A is by impeller shaft 2A1 fixedly on the locular wall of oil curtain chamber 1D.Above structure makes jet power that blade 2A5 need only be less just can obtain the rotation of continuous high speed, and it is necessary that this produces oil curtain just.The shape of blade 2A5 and setting angle directly have influence on the quality of oil curtain and the energy size of consumption.The blade 2A5 that the utility model adopted is the right angle strip, evenly distribute and be fixed between two impeller frame 2A4, and wherein an arm of angle and impeller frame 2A4 radially is 20 ° of-40 ° of angles, can adopt 6-10 blade to be evenly distributed on the circumference.

The effect of filter 5 is to tackle the remaining machine oil that purifies in the tail gas stream of back, forms so the mixed and disorderly unordered twine 5B that is with 5A container with holes and container is gone up in its design, can effectively draw to cut machine oil and it is back to purify in the chamber.

The tail gas cleaner for motor-driven vehicle of making according to above design, simple in structure, easy for installation, its purifying effect is fairly obvious, particularly can remove flue dust more than 90% to diesel vehicle tail gas, black smoke is bleached, and effectively remove the harmful matter that the people is coughed shed tears, the long-range prospect of applying is arranged.
