Description
Technical field：
The invention belongs to a kind of automobile exhaust purifiers, are a kind of dismountable plasma wood-fibred vapour more specifically
Tailstock gas purifier is installed to exhaust system muffler rear, can effectively purify the PM and NO of vehicle exhaustx。
Background technology：
Diesel engine has long lifespan, power bracket is wide, power is strong and low speed is turned round compared with other locomotives of equal-wattage
The advantages that square is big, but the PM and NO that diesel engine is dischargedxSerious influence is caused on environment, at present low temperature plasma skill
Art is acknowledged as one of most promising motor exhaust post-processing technology, but since complicated, purification efficiency are low and
The reasons such as of high cost seriously limit application of the low temperature plasma in purifying vehicle exhaust field, therefore research and develop a kind of with knot
Structure is simple, occupy little space, automobile exhaust purifier at low cost and easy-to-dismount is particularly important.
The content of the invention：
Problem to be solved by this invention is：The existing automobile exhaust purifier structure based on lower temperature plasma technology
The problems such as complicated, of high cost and difficult dismounting.
A kind of dismountable plasma wood-fibred automobile exhaust purifier.It is characterized in that：The purifying vehicle exhaust
Device, by ring flange, exhaust outlet, electrode wires, preceding clean room, clean room, after-purification room, wood-fibred filter core, fair water cone, air inlet,
Cartridge support frame, insulating carriage, insulating conical plug composition.The ring flange one and ring flange two respectively with air inlet and exhaust
Mouth sealing welding, the muffler rear that automobile exhaust purifier is made to be easily mounted in automobile exhaust system；The electrode wires are L
Type copper rod, one end are inserted into conical plug, and the other end is fixed on the axial location of clean room by insulating carriage；The purification
Room is divided into former and later two clean rooms and is connected using pipe screw thread, makes clean room easy to disassemble；The wood-fibred filter core is in inside
Empty cylindrical shape makes it keep coaxial with clean room by cartridge support frame.
Advantageous effect：Lower temperature plasma technology and wood-fibred filter core are used in combination for the invention, can purify simultaneously PM and
NOx, so reduce the occupied space of automobile exhaust purifier；Its removable structure can be convenient for changing discarded filter core and
Cleaning room allows the automobile exhaust purifier to recycle to achieve the purpose that reduce cost.
Description of the drawings：
Fig. 1 is a kind of dismountable plasma wood-fibred automobile exhaust purifier structure chart of the present invention.
In figure：It is one 1-1 of ring flange, two 1-2 of ring flange, exhaust outlet 2, electrode wires 3, after-purification room 4-1, clean room 4, preceding net
Change room 4-2, wood-fibred filter core 5, fair water cone 6, air inlet 7, cartridge support frame 8, insulating carriage 9, insulating conical plug 10.
Specific embodiment：
Below by embodiment combination attached drawing, the invention will be further described.
Example 1：
A kind of dismountable plasma wood-fibred automobile exhaust purifier, it is characterised in that：The purifying vehicle exhaust
Device, it is fine by ring flange 1-1, ring flange 1-2, exhaust outlet 2, electrode wires 3, after-purification room 4-1, clean room 4, preceding clean room 4-2, wood
Dimension filter core 5, fair water cone 6, air inlet 7, cartridge support frame 8, insulating carriage 9, insulating conical plug 10 form.The ring flange one
1-1 and two 1-2 of ring flange with 2 sealing welding of air inlet 7 and exhaust outlet, makes automobile exhaust purifier be easily mounted on automobile respectively
Muffler rear in exhaust system；The electrode wires 3 are L-type copper rod, and one end is inserted into insulating conical plug 10, and the other end passes through
Insulating carriage 9 is fixed on the axial location of clean room；The clean room 4 is by after-purification room 4-1 and preceding clean room 4-2 groups
Into front and rear clean room is connected using pipe screw thread, is conveniently replaceable discarded filter core and cleaning room；The wood-fibred filter core 5 is
The cylindrical shape of inner hollow as the discharge medium of dielectric barrier discharge reactor, is made by the fixation of cartridge support frame 8
It keeps coaxial with clean room 4.When use, first electrode wires 3 and wood-fibred filter core 5 are mounted in clean room, then will
Preceding clean room 4-1 and after-purification room 4-2 are tightened, and are finally arranged the automobile exhaust purifier assembled mounted on automobile with ring flange
In gas system.When automobile starting, electrode wires 3 connect high voltage power supply, and PM can be trapped by purifying indoor wood-fibred filter core 5, simultaneously
The active material generated in clean room can reduce NOxWith oxidation PM, the pollution of lower temperature plasma technology cleaning of off-gas is improved
Efficiency simplifies the complexity of clarifier.When filter element life reaches limit value, after-purification room 4-1 and preceding clean room 4-2 are twisted
It opens, you can replace filter core, also purification chamber interior walls capable of washing.
The described dismountable plasma wood-fibred automobile exhaust purifier of this example can Reusability, and wood-fibred filter
Core is at low cost, and the program can be as the effective ways of diesel car tail gas refining.
