徴とする廃油処理法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waste oil treatment method, and more specifically,
The primary treatment sludge of oil-containing wastewater discharged during the cleaning and regeneration of oil-containing cleaning materials such as motu and mats is filtered under pressure, and the oil-containing wastewater resulting from this pressure filtration is subjected to oil-water separation based on the difference in specific gravity, and the resulting waste oil is filtered. The present invention relates to a waste oil treatment method characterized by removing dust from the waste oil, mixing the filtered waste oil and heavy oil at a weight ratio of 1=99 to 40:60, and burning the mixture in a boiler burner.

情である。A system has been adopted in which the oil-impregnated fibers are lent to users for a certain period of time, and after the used oil-impregnated fibers are washed and treated with oil, they are shipped again to study demand. The oil-containing wastewater generated during this cleaning is treated by adding a flocculant such as sulfuric acid, adjusting the pH, etc.
For the next treatment, the oil-containing sludge is floated and separated, the separated wastewater is subjected to secondary treatment and sixth treatment which are known per se, and then discharged, while the oil-containing sludge is applied to a filter press to separate the oil-containing wastewater, This oil-containing wastewater is subjected to oil-water separation to separate it into waste oil and wastewater. This waste oil still contains a considerable amount of dust, and it is difficult to reuse it for any purpose, and the reality is that this waste oil is ultimately disposed of.

した。The present inventors have found that when the waste oil separated from the oil-containing wastewater described above is subjected to the dust separation described below, and then mixed with heavy oil etc. at a certain ratio, this mixed oil has the same flammability and calorific value as heavy oil. It was found that it can be fully used as a fuel.

aL/Kg) 10.890 10.734 From the above table, it can be seen that this waste oil has properties similar to A heavy oil and can be handled on the same level as A heavy oil. In addition to the waste oil storage tank 5 described above, a heavy oil tank 17, a mixing tank 18, and a burner 19 are provided.

としてバーナーに供給することが重要となる。In the present invention, this waste oil and heavy oil are mixed in a ratio of 1:99 to 4:
0:60. In particular, it is important to use them at a weight ratio of 5:95 to 30:70, and to mix the two sufficiently to prepare a burner fuel. In other words, even if the waste oil used has been separated from oil and water, it still contains a considerable amount of water and has a high viscosity, so in order to burn it in a normal heavy oil burner, it is necessary to mix the two evenly. It is important to supply this to the burner with a uniform composition.

んど意味をなさなくなる。It is also important to mix waste oil and heavy oil in the above-mentioned ratio; when the ratio of waste oil is higher than the above range, combustibility tends to decrease slightly. In terms of waste oil treatment, reducing the amount of oil has almost no meaning.
廃油と重油との混合比率の制御は、定量ポンプ２０と２

There is a risk that this may not clog the burner chip, but this drawback can be overcome by providing strainers 22 and 25 in the waste oil supply system to the mixing tank and the mixed oil supply system to the burner, respectively.
