Art.
Technical background：
At present, automobile exhaust purifier is to reduce the most effectual way of engine combustion pollutant emission.
The main composition of automobile exhaust purifier has：Metal shell, pad and carried catalyst；Wherein, carried catalyst
It is the core component that processing discharges pollutants.It is in fact exactly that the transformation efficiency of carried catalyst can not expire that motor vehicle emission is not up to standard
Sufficient national environmental standard, such as state four, state five.
Cause carried catalyst transformation efficiency low, or conversion capability has many reason for completely lose, wherein most normal
What is seen is：1st, substantial amounts of carbon distribution covers catalyst coat；2nd, fuel oil or Pb in fuel oil additive, Zn, Ca, Mn, Fe, Cu,
Catalyst poisoning caused by the elements such as Ni, P, S.
The content of the invention：
In view of the above-mentioned problems, the invention discloses a kind of avoid-dismantle ternary catalyzing unit regeneration techniques.Pass through the method for preceding lambda sensor
Blue mouth, portable media reproduction equipment is connected with blast pipe, in situ to return to the carried catalyst be poisoned, failed without dismounting
The level dispatched from the factory close to original car.
To reach above-mentioned purpose, technical scheme provided by the present invention is：
Avoid-dismantle ternary catalyzing unit regeneration techniques, comprises the following steps：
First, generating apparatus and ternary catalyzing unit again are connected, by the flange port of preceding lambda sensor, by portable media reproduction equipment and exhaust
Pipe is connected；
2nd, carbon distribution is calcined, by the hot air duct of portable media reproduction equipment, hot blast is blown out to ternary catalyzing unit, carbon distribution is burnt
Fall；
3rd, purge, turn off the heater switch of portable media reproduction equipment, while blower fan air output is adjusted into maximum, the product of residual
Carbon and dust purging are clean；
4th, clean, when hot blast temperature is down to 200 DEG C, pass through the cleaning agent injection pipe jet cleaning of portable media reproduction equipment
Agent；
5th, active liquid supplement, active liquid is sprayed by the renovation agent injection pipe of portable media reproduction equipment；
6th, dry, by the hot air duct of portable media reproduction equipment, blow out hot blast to ternary catalyzing unit, active liquid is dried；
7th, activate, by the hot air duct of portable media reproduction equipment, blow out hot blast to ternary catalyzing unit, active liquid is activated；
8th, disconnect, complete regeneration.
Further, the hot blast temperature in step 2 is 300 DEG C ~ 500 DEG C, and the duration is 5 ~ 20 minutes, and the specific time regards
Catalyst converter aging performance is determined.
Further, in step 4, the main component of cleaning agent is hydrochloric acid, hydrogen peroxide, chelating agent.
Further, in step 5, active liquid is the renovation agent using Pt, Pd, Rh as main active component.
Further, the hot blast temperature in step 6 is 80 ~ 200 DEG C.
Further, water rate is gone to reach 100% in step 6.
Further, the hot blast temperature in step 7 can not be less than 500 DEG C.
Further, in step 7, time of the temperature more than 500 DEG C must not be less than 5 minutes.
It is an advantage of the invention that：Ternary catalyzing unit regeneration techniques of the present invention, without dismantling ternary catalyzing unit, operation
It is convenient and swift, ternary catalyzing unit carbon distribution both can be effectively removed, Pb, Zn, Ca, Mn, Fe, Cu, Ni, P, S etc. can be removed again to be had
Evil element, while the carried catalyst be poisoned, failed can be returned to the level dispatched from the factory close to former car.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
Skilled artisan understands that.
Comprise the following steps：
By the flange port of preceding lambda sensor, portable media reproduction equipment is connected with blast pipe, it is ensured that hot blast, cleaning agent and reparation
Agent critical point is directed at ternary catalyzing unit, opens blower fan and heater switch, air quantity is adjusted between the 0.5 ~ 0.25 of maximum quantity of wind, leads to
The hot air duct of portable media reproduction equipment is crossed, hot blast is blown out to ternary catalyzing unit, carbon distribution is burnt completely, notices that temperature can not
Less than 300 DEG C, 500 DEG C can not be higher than, the serious ternary catalyzing unit of aging is time-consuming 20 minutes or so, after burning completely,
Turn off the heater switch of portable media reproduction equipment, while blower fan air output is adjusted into maximum, carbon distribution and the dust of residual are purged
Totally, when hot blast temperature is down to 200 DEG C, the cleaning agent injection pipe jet cleaner of portable media reproduction equipment, cleaning are passed through
The main component of agent is hydrochloric acid and hydrogen peroxide, while also after the completion of cleaning, then passing through portable media reproduction containing chelating agents such as EDTA
The renovation agent injection pipe of equipment sprays the active liquid by main active component of Pt, Pd, Rh, treats that active liquid is fully dispersed in three
After on first catalyst converter, then by the hot air duct of portable media reproduction equipment, hot blast is blown out to ternary catalyzing unit, active liquid is dried
Dry, drying temperature is 80 ~ 200 DEG C, while going the requirement of water rate to reach 100%, is set when being completely dried, then by portable media reproduction
