    Waste liquid of medium wire cutting fluid and how to deal with it environmentally

    release time:2018-12-25  viewed:5720次
    How to discharge the liquid used in the middle traveling wire well?
    1. Selection of Processing Fluids
    It is necessary to choose environmentally friendly cutting fluid. Real environmentally friendly processing fluid must not contain harmful substances such as sodium nitrite, silver nitrite, hexapotassium chromium, heavy metals and pollution sources. Most of the cutting fluids on the market are semi-synthetic water-soluble oils, which contain a lot of non-standard mineral oils, which can not be called real environmental protection cutting fluids.
    2. Machine Tool Workplace Cleaning
    In the actual processing and production, the old liquid contains a lot of mixed metal powders and impurities such as molybdenum, iron, carbon powder, oil sludge, and so on. A certain amount of debris and dirt are accumulated in the dead angle of the water tank and the inside of the pipeline, pump and valve filter screen. When changing liquids, water tanks, workbenches and pipes need to be cleaned, and some detergents can be added to complete the cleaning.
    3. Filtration method of incision fluid
    Fixed waste residue is filtered out:
    (1) The old liquid is filtered by non-woven cloth, which relies on the gravity of the liquid to pass through the non-woven cloth and isolate impurities such as sludge.
    (2) Oil sludge and solid particles can be filtered out.
    (3) Conditional users can buy a portable oil filter and filter the old liquid twice.
    (4) The filtered sludge and solid particulate matter gather and flourish.
    (5) Assuming 300 kg of old liquid, about 60 kg of particulate matter and sludge can be filtered out after two filtrations.
    (6) According to the treatment standard of solid waste, solid waste of particulate matter and oil sludge should be packed in nylon bags and classified for waste treatment.
    4. Dilution and Emission
    For example, how many kilograms of liquid remain, need to add 10 times the dilution of tap water. So there is almost no pollution, the diluted liquid can be discharged directly; it can also be used for recycling and secondary use, and can also be used for industrial floor cleaning, toilet cleaning.
