Abstract
The present invention relates to a kind of Method for ultrasonic removal of carbon deposition.Technical scheme of the present invention: a kind of Method for ultrasonic removal of carbon deposition, comprises the steps: part oil removing, makes carbon remover tank liquor, ultrasonic wave carbon remover, hcl corrosion.Method for ultrasonic removal of carbon deposition of the present invention, utilizes the carbon remover tank liquor of special formulation, has the advantage that carbon remover speed is fast, quality is high, be easy to realization, reduces general chemistry infusion method carbon remover pollution on the environment simultaneously.
Description
Technical field
The present invention relates to a kind of carbon removing method, particularly relate to a kind of Method for ultrasonic removal of carbon deposition.
Background technology
Carbon distribution is fuel and the product of lubricating oil under high temperature oxidation effect.In a combustion chamber, oxygen supply is not enough, fuel and scurry into the lube stock of combustion chamber can not perfect combustion, and produce oil smoke and tar particles, after they and lubricating oil mix, be oxidized into consistence colloidal liquid further, stick to securely on nozzle, and under the continuous effect of high temperature, colloid aggregates into again more complicated polymkeric substance, i.e. carbon distribution.And engine temperature is higher, the carbon distribution of formation is also more hard tightr, and participant belongs to bonding and closes firmly.Carbon distribution is as unclean in cleaning, will waste fuel oil, and have a strong impact on the work-ing life of engine.
What generally adopt in the market is chemical immersion method carbon remover.Namely utilize 741 washing composition of 1% ~ 10%, soak for a long time, generally all will control at more than 24h.But thoroughly cannot remove for some obstinate carbon distributions like this, local mechanical can only be leaned on to polish, but adopt this to operate, easy damaging substrate, causes scrapping of part again.
Summary of the invention
The invention provides a kind of Method for ultrasonic removal of carbon deposition, utilize the carbon remover tank liquor of special formulation, there is the advantage that carbon remover speed is fast, quality is high, be easy to realization, reduce general chemistry infusion method carbon remover pollution on the environment simultaneously.
Technical scheme of the present invention is as follows:
A kind of Method for ultrasonic removal of carbon deposition, comprises the steps:
(1) by part oil removing: employing acetone is degreaser, is immersed in by part in degreaser, at room temperature soak oil removing 20 ~ 120 minutes, dry in atmosphere or dry up; Put into 60 ~ 80 DEG C of alkali lye and carry out electrochemical deoiling, cleaning oil pollution is clean, then carry out hot water wash and cold wash, clean the alkali lye of piece surface remnants;
(2) carbon remover tank liquor is made: carbon remover tank liquor formula is: potassium permanganate 10 ~ 35g/L, sodium hydroxide 25 ~ 50g/L, sodium dichromate 99 5 ~ 10g/L; Respectively described potassium permanganate, sodium hydroxide, sodium dichromate 99 are thoroughly dissolved with 40 ~ 60 DEG C of hot water, be placed in the groove with ultrasonic equipment, carbon remover tank liquor is stirred;
(3) ultrasonic wave carbon remover: the part after oil removing is put into described carbon remover tank liquor, control ultrasonic frequency at 20 ~ 30kHz, carbon remover tank liquor temperature at 40 ~ 60 DEG C, a part is overturn every 20 ~ 40min, until the thorough Ex-all of the carbon of piece surface black, piece surface local presents matrix metal gloss; Taken out by part, with hot water wash and cold wash, the alkali lye that piece surface is residual is thoroughly removed;
(4) hcl corrosion: because alkali lye and carbon distribution reaction can form oxide compound, be attached to piece surface, part is put into hydrochloric acid, the oxide compound of piece surface is removed, when part presents the matrix having metalluster, the carbon on part is thoroughly cleaned out; Then rinse part surfaces externally and internally with water blast gun, then put into hot water and clean, then make part rapid drying in atmosphere, finally dry up with pressurized air.
Beneficial effect of the present invention:
1, carbon remover tank liquor formula of the present invention is: potassium permanganate 10 ~ 35g/L, sodium hydroxide 25 ~ 50g/L, sodium dichromate 99 5 ~ 10g/L; Wherein potassium permanganate 10 ~ 35g/L and sodium hydroxide 25 ~ 50g/L loosens with the use of carbon surface rigid structure can be made to produce, and then it is inner to corrode carbon, improves carbon remover speed; Potassium permanganate is first for carbon remover tank liquor formula in this area, carbon remover successful.
2, in carbon remover tank liquor formula of the present invention, sodium dichromate 99 can play the effect of protection part metallic matrix, prevents part excessive erosion.
3, hyperacoustic cavitation effect combines with the solvency action of pharmaceutical chemicals to carbon distribution by the present invention, reaches the object of thorough decarbonizing.The shock action that ultrasonic vibration produces in a liquid and the high-speed micro-jet that ultrasonic cavitation produces on solid and liquid surface can remove or weaken the carbon on border, increase stirring action, accelerate the dissolving of carbon, strengthening carbon remover tank liquor is to the chemical dissolution effect of carbon.
4, adopt above-mentioned processing method carbon remover, the repairing of engine fuel nozzle can be successfully applied to.After nozzle burner carbon distribution is removed, surperficial metal luster, nozzle opening air-flow is unobstructed, meets design requirement, it can be made to recover recycling, saved production cost, increased work efficiency more than 8 times.
