Abstract
The utility model relates to an air exhaust pipe of engine, and comprises an air exhaust filter core or a supporter that is arranged inside the air exhaust pipe body, and a microwave apparatus is arranged at one end of the air exhaust filter core or the supporter, then a metal mesh blocker is arranged at the other end. The utility model mainly solve the technical problem of the prior filter core or the supporter in exhaust air pipe of engine and is favorable to the environment protection, that is the not good filter effects caused by the higher fire temperature of media.
Description
Technical field:
The utility model relates to venting gas appliance, particularly engine exhaust pipe.
Background technique:
Motor, in industry, play the part of extremely important role, generally can be divided into two kinds of diesel engine and petrol engines, these two kinds of motors all can produce black smoke, waste gas in use, and this black smoke, the waste gas maximum arch-criminal that is air-polluting, national governments are defined in filtrating equipments such as need installing filtering element (cartridge) on the waste pipe additional mostly in order to reduce its atmospheric pollution, wherein, again with the strictest to the regulation of the traffic tool (such as aircraft, vehicle, boats and ships etc.).Be coated with catalyst in the filtering element (cartridge) passage of available engine outlet pipe, catalyst is a kind ofly can order about catalysis and produce the chemical substance of spontaneous combustion when reaching uniform temperature more, make approximately 375 ℃ of needs of temperature that catalyst produces spontaneous combustion.In the diesel oil part:,, be referred to as carbon distribution usually when work so can produce in the passage that particulate matter lodges in filtering element (cartridge) because the particle of carbon microsphere that diesel engine produces is bigger.The gas temperature that carbon distribution needs to discharge by motor can make the catalyst that is coated in the filtering element (cartridge) passage carry out chemical change and spontaneous combustion, and its carbon distribution is burnt up to more than 375 ℃.Reach this high temperature, not only need the long time, and can produce new carbon distribution during this period and can't fully burn.Time one is of a specified duration, will cause the inefficacy of filtering element (cartridge).And in the gasoline part: though the carbon distribution phenomenon as diesel engine is so not serious, but the reaction and the catalytic temperature of the catalyst in the filtering element (cartridge) passage also are quite high, often need more than 250 ℃, therefore, also need long period of time just can play effect, reduced filtering effect.
The model utility content:
The utility model will solve filtering element (cartridge) or the carrier in the available engine outlet pipe, causes the not good technical problem of filtering effect owing to the initiation temperature of catalyst is higher, and a kind of engine exhaust pipe of new structure is provided.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of engine exhaust pipe comprises the exhaust filtering element (cartridge) that is positioned at the outlet pipe body, it is characterized in that: this exhaust filtering element (cartridge) one end has a microwave device, and the other end has a wire netting piece.
This exhaust filtering element (cartridge) skin is coated with a ceramic wool and metal cylinder respectively.
A kind of engine exhaust pipe comprises the carrier that is positioned at the outlet pipe body, it is characterized in that: this carrier one end has a microwave device, and the other end has a wire netting piece.
This carrier skin is coated with a ceramic wool and metal cylinder respectively.
Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect.
The utility model mainly is provided with a microwave device in the air inlet of exhaust filtering element (cartridge) or carrier or arbitrary place of outlet side, can be directly order about carbon distribution particle or the foreign particle burning that lodges in the filtering element (cartridge) passage, also can order about catalyst and comparatively fast reach initiation temperature by the high temperature that microwave radiation produces by the high temperature of microwave radiation.Wire netting piece in the other end setting then can prevent leaking outside of microwave radiation effectively.
Description of drawings:
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is an assembled sectional view of the present utility model.
Fig. 3 is user mode of the present utility model (diesel engine) schematic representation one.
Fig. 4 is user mode of the present utility model (petrol engine) schematic representation two.
Embodiment:
See also Fig. 1,2, they are structural representations of the present utility model.As shown in the figure: the utility model is exhaust filtering element (cartridge) 1 or the carrier of being located in the engine exhaust pipe 41 ', be equipped with a microwave device 2 in the air inlet of exhaust filtering element (cartridge) 1 or carrier 1 ' or arbitrary end place of air outlet, and for to prevent that the source of radiation of microwave from leaking outside, the exhaust filtering element (cartridge) 1 in outlet pipe 4 or the other end place of carrier 1 ' are provided with a wire netting piece 3, and the heat energy of filtering element (cartridge) 1 or carrier 1 ' is kept effectively.Skin at filtering element (cartridge) 1 or carrier 1 ' also is coated with a ceramic wool 5 and metal cylinder 6 respectively.
See also Fig. 3,4 again, they are user mode schematic representation of the present utility model.As shown in the figure: when starting microwave device 2, microwave device 2 i.e. launched microwave radiation 21 in the passage 11 of filtering element (cartridge) 1 or carrier 1 ', at this moment, microwave radiation 21 is done and the opposite conduct of black smoke toxic emission direction, promptly pass the inlet end of the passage 11 of filtering element (cartridge) 1 or carrier 1 ' to outlet pipe 4 from the outlet side of outlet pipe 4, because the microwave radiation 21 that microwave device 2 is produced has high temperature, therefore, outlet pipe (as Fig. 3) for diesel engine, can make soot particle 7 that lodges in the filtering element (cartridge) passage 11 do not need by or wait for that the catalyst that is coated in the filtering element (cartridge) passage 11 carries out directly making its burning by microwave radiation 21 under the chemical change of spontaneous combustion.And when using petrol engine (as Fig. 4), microwave radiation 21 will be accelerated catalyst and reach initiation temperature.
