Detailed description of the invention
The embodiment of this utility model structure is described in detail in conjunction with accompanying drawing:
A kind of diesel engine after treatment device that can be recycled, it is characterised in that: include end gas catalytic oxidation device and micro-
Grain two major parts of collection device.End gas catalytic oxidation device includes pressure transducer 11 that two specifications are identical and 9, two
Oxidation catalyzer (DOC) 12 and 13 that specification is identical, granule oxidation catalyzer (POC) 10, two pressure transducers 9 and 11 are installed
In the port of exhaustor, determine whether blocking, the oxidation that two specifications are identical for monitoring the pressure of exhaustor front and back end
Catalyst converter (DOC) 12 and 13 is arranged on the position of the intermediate symmetry of exhaustor and has certain interval, for by tail gas
Carbonoxide (CO), nitric oxide (NO), hydrocarbon (CH) oxidation catalysis, granule oxidation catalyzer (POC) 10 is arranged on two specifications
The position of the middle of identical oxidation catalyzer (DOC) 12 and 13, for aoxidizing the catalysis of carbon granule (C).Described above
DOC be to be to be precious metal with palladium (Pd) and rare earth metal is constituted by platinum (Pt), with aluminium oxide as catalyst carrier, electromotor
When aerofluxus is by catalyst converter, chemical reaction activation energy reduces, HC and CO can the most quickly with the residual of aerofluxus
O2Reaction, generates CO2And H2O, realizes the purpose of HC and CO in purification diesel engine.POC needs in higher regeneration temperature,
Therefore need with DOC with the use of, when delivery temperature is between 200 DEG C～500 DEG C, POC carrier is substantially carried out 2NO+O2→
2NO2、C+2NO2Two chemical reactions of → CO+2NO.After aerofluxus is by DOC (oxidation catalyzer) and POC (grain catcher),
Tail gas may also have remaining HC and CO, now enter one in tradition after-treatment device (DOC+POC) by installing a DOC additional
Step purifies so that purification efficiency is higher.By pressure transducer and the pressure of second DOC rear end of first DOC front end of detection
Force transducer voltage difference judges whether post processing blocks.
The waste gas first passing around electromotor discharge enters from exhaust gas entrance 14, is then passed through oxidation catalyzer (DOC) 13 right
Tail gas carries out catalysis oxidation, passes through the microgranule in the tail gas of granule oxidation catalyzer (POC) 10 pairs of diesel engines and processes,
Through oxidation catalyzer (DOC) 12, further vent gas treatment can be improved purification efficiency, the pressure biography that now two specifications are identical
The pressure of end before and after exhaustor is monitored by sensor 9 and 11 respectively, and once to exceed regulation poor for the pressure difference value of front and back end
Value, illustrates that after-treatment device occurs serious blocking, this signal is fed back to driver, then operation of turning around exhaustor,
Starting electromotor utilizes its air-flow that DOC, the POC in exhaustor is carried out blowback, and the tamper being blocked on DOC, POC can be with
The highest speed enters particle collection device.Baffle plate 3 is arranged on and covers, and for changing the airflow direction of tail gas, makes exhaust gas flow
Rotating, first granule can be with the highest speed from shell 7 (lid 6, shell 7 are for the sealing to particulate collection device) and shelves
Pulling in the crack between 3 and flow into and to descending, bigger tamper has bigger inertia, rushes on the machine oil face of oil sump 8, quilt
Machine oil adheres to.Pallet 2 is arranged on waste gas outlet 1 pipeline, is in shell 7 internal, is used for supporting and fixing filter element, at filter element 4
In the inner side of baffle plate 3, lid 6 and the centre of pallet 2, it is used for filtering microgranule, relatively gently thinner tamper turns to filter element 4 to flow with air-flow
Go, adhered to filter by filter element 4.So granule in double-filtration, air-flow is cut, and the cleaning tail gas of filtering is from useless the most
Gas is given vent to anger in 1 inflow air, and sticks to the tamper on filter element 4, due to cleaning, gradually of the elaioleucite by being taken up by air-flow
Being back in oil sump 8, oil sump 8 is below pallet 2, and oil sump 8 liquid level and pallet 2 have a certain distance, are used for depositing height
Viscosity, resistant to elevated temperatures machine oil.This composite type particulate trap, small volume structure clean cycle simple, removable uses.Can basis
The size of automobile discharge capacity selects the structure adapted.When utilizing motor exhaust to carry out blowback, in order to prevent lasting high temperature
Exhaust gas flow causes the volatilization of the machine oil in the machine oil pond of composite type particulate trap, can deposit high viscosity, high temperature resistant in oil sump 8
Machine oil (used oil can be deposited), when two pressure transducer 9 and 11 force value are of substantially equal, illustrate that DOC is substantially dry by purging
Only, exhaustor normally uses.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to
Assert that of the present utility model being embodied as is confined to these explanations.Ordinary skill for this utility model art
For personnel, make some equivalents without departing from the concept of the premise utility and substitute or obvious modification, and performance or
Purposes is identical, then should be considered as belonging to the protection domain that claims that this utility model submitted to determine.
