Abstract
The invention relates to a method for cleaning a three-way catalytic converter. The method comprises the following steps: the three-way catalytic converter of which surface is flushed is placed in a groove body of an ultrasonic cleaning machine; tap water is added into the ultrasonic cleaning machine till reaching a water line, and then concentrated cleaning liquid is added into the tap water and stirred uniformly to constitute mixed solution for cleaning; the three-way catalytic converter is fully soaked by the mixed solution; the ultrasonic cleaning machine is turned on to carry out ultrasonic cleaning; the ultrasonic cleaning machine is opened to discharge liquid waste in the groove body after the cleaning work of the ultrasonic cleaning machine is finished; and after the tap water is added into the ultrasonic cleaning machine for flushing the inside of the three-way catalytic converter, the three-way catalytic converter is demounted to be air-dried naturally. By using the ultrasonic to clean the three-way catalytic converter, damage to the three-way catalytic converter, which is caused by suspended-bottle-type cleaning, is avoided while the cleaning effect is effectively guaranteed.
Description
Technical field

3) open described supersonic cleaning machine, carry out ultrasonic cleaning;
4) after described supersonic wave cleaning machine cleaning finishes, open described supersonic wave cleaning machine and discharge the waste liquid after the cleaning in the cell body;
5) after the adding running water washes ternary catalyzing unit inside in the supersonic wave cleaning machine cell body, unload ternary catalyzing unit, natural air drying.
Further, also comprise pre-treatment step before the step 1, by observing the inside of ternary catalyzing unit, pick out inner sintering and stop up the ternary catalyzing unit pipeline or exist physically impaired ternary catalyzing unit not deal with that other ternary catalyzing unit is used for step 1.
Further, adding concentrated cleaning solutions in the described step 2 is that the cleaning agent of 500ML ternary catalyzing unit and the amount of putting into running water are 160L-180L.
Further, described ultrasonic drilling machine resonance generation frequency is higher than 20KHz.
Further, the time of the ultrasonic cleaning in the described step 3 is 20MIN-30MIN;
Further, the time of the flushing in the described step 5 is 5MIN-10MIN.
Compared with prior art, the present invention has following beneficial effect: utilize ultrasonic echography to produce acoustic energy, acoustic energy is radiated in the cleansing medium, when the sound intensity surpasses the cavitation threshold of cleansing medium, meeting generation micro-wave acts on and is cleaned the object surface, thereby dirt is peeled off rapidly, is adopted the method for Ultrasonic Cleaning ternary catalyzing unit to have the following advantages:
1, effectively decarbonizing and sulfur-containing, phosphorus-containing deposit;
2, cleaning effect is better, and is cleaner;
3, flushing process can be to the inside injury of ternary catalyzing unit.
The specific embodiment
Example of the present invention is can not limit the present invention to explanation of the present invention, in the implication suitable with the present invention and any change and the adjustment in the scope, all should think within the scope of the invention.
The present invention will be further described below in conjunction with embodiment.
A kind of cleaning method of ternary catalyzing unit comprises step:
1) ternary catalyzing unit of appearance through flushing is positioned in the supersonic wave cleaning machine cell body;
2) put running water to waterline at described supersonic wave cleaning machine, add again concentrated cleaning solutions and stir evenly the mixed liquor that is configured for cleaning; So that described mixed liquor fully soaks described ternary catalyzing unit;
3) open described supersonic cleaning machine, carry out ultrasonic cleaning;
4) after described supersonic wave cleaning machine cleaning finishes, open described supersonic wave cleaning machine and discharge the waste liquid after the cleaning in the cell body;
5) after the adding running water washes ternary catalyzing unit inside in the supersonic wave cleaning machine cell body, unload ternary catalyzing unit, natural air drying.
Preferably, before step 1, also comprise pre-treatment step, by observing the inside of ternary catalyzing unit, to pick out deposit and sintered bulk into and stop up the ternary catalyzing unit pore or exist physically impaired ternary catalyzing unit not deal with, other ternary catalyzing unit is used for step 1.
Concrete, the ternary catalyzing unit of Partial Blocking or inefficacy is carefully pulled down, by observing the inside of ternary catalyzing unit, also comprise pre-treatment step before the step 1, by observing the inside of ternary catalyzing unit, pick out and stop up serious or have the ternary catalyzing unit of physical damnification such as crackle, breakage etc. not deal with, rinse well with running water other ternary catalyzing unit outside; Before putting into ternary catalyzing unit, at first will clean up in the supersonic wave cleaning machine cell body, to prevent the impurity that its inside exists ternary catalyzing unit is caused secondary pollution.
Ternary catalyzing unit is put into the supersonic wave cleaning machine cell body, puts running water to waterline at described supersonic wave cleaning machine, and the amount of described running water is 160L-180L, adds concentrated cleaning solutions again and stirs evenly the mixed liquor that is configured for cleaning; Concentrated cleaning solutions is the cleaning agent of 500ML ternary catalyzing unit; The cleaning agent of ternary catalyzing unit is in existing patent " cleaning agent of automobile three-way catalysts ", by the agency of in the patent No. 200810010534.7, be not further elaborated in this patent, the adding mixed liquor has effectively strengthened the cleaning performance of supersonic wave cleaning machine, avoid simultaneously utilizing in the prior art transfusion bottle mode directly to ternary catalyzing unit internal spray cleaning agent, participate in burning, improve the temperature of combustion gas, remove the pollutant on the three-way catalytic converter carrier, this mode is to the damage of the inside of ternary catalyzing unit; Promote the life-span that ternary catalyzing unit uses.So that described mixed liquor fully soaks described ternary catalyzing unit; Like this, when carrying out ultrasonic cleaning, could fully clean inside and the outside of ternary catalyzing unit.
