Technical Field
The invention relates to the technical field of cutting fluid atomization treatment, in particular to a cutting fluid oil atomization microwave plasma treatment device and a treatment process thereof.
Background
Cutting fluid is an industrial fluid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Currently, the cutting fluids sold on the market are classified into water-soluble (water-based) fluids and water-insoluble (oil-based) fluids according to the chemical composition of the oil product.
Oil-based cutting fluids generally do not deteriorate due to odor, and the reason for replacing the cutting fluid is mainly due to chemical changes of the cutting fluid, an increase in the amount of mixed chips, leakage of a large amount of machine tool lubricating oil, mixing of water, and the like. The final treatment of waste oil with oil-based cutting fluid is generally a combustion treatment, and waste oil may be regenerated in order to save resources. The waste liquid treatment of the water-based cutting fluid can be classified into physical treatment, chemical treatment, biological treatment and combustion treatment. Since the compositions of water-based cutting fluids vary, there has been no fixed method for treatment, and the above-mentioned methods are generally used in combination according to the properties of the waste fluid to be treated.
The components of the cutting fluid are complex, the waste water has the characteristics of high COD value, high content of ammonia nitrogen and phosphorus, high content of organic matters such as emulsion and the like, the treatment difficulty is high, and particularly, the emulsion in the water is difficult to remove in the conventional method. Therefore, the method is urgently needed to provide a method which can better remove organic matter components such as COD, ammonia nitrogen and phosphorus in the cutting fluid wastewater and realize the standard discharge of the cutting fluid wastewater.
