Description

Technical Field

[0001] The invention relates to the technical field of oily sludge analysis and detection, and in particular to an instrument and method for rapid separation and determination of oil, water and solid three phases of oily sludge. Background Art

[0002] In the analysis and testing standards for oily sludge, two standard measurement methods are used for the determination of oil content, water content, and solid content, namely:

[0003] (1) CJT 221, “Test Methods for Sludge from Municipal Wastewater Treatment Plants”

[0004] Among them, it involves mineral oil determination, and the total oil content is determined by infrared spectrophotometry;

[0005] (2) HJ613-2011, Gravimetric method for determination of soil dry matter and moisture

[0006] Determine the moisture / solids content.

[0007] The above method has the following disadvantages:

[0008] (1) The moisture content / solid content is determined by the gravimetric method. When the oil sludge is dried at 105°C, some light oil will evaporate along with the water vapor, causing the moisture content test value to be greater than the actual value.

[0009] (2) The oil content calculation formula in CJT 221 is the oil content of Soxhlet extraction divided by the dry solid content, and the dry solid content comes from the solid content determined by the above-mentioned gravimetric method. This solid content is the water-free solid content of the dichotomy method, and it still contains a lot of heavy oil. If the oil content is high, a large error will occur;

[0010] (3) The above test method has very high requirements for the configuration of experimental instruments and the professionalism of operators. It needs to be equipped with a Soxhlet extractor, a water bath, an extraction sleeve, cotton wool, a grinding mortar, an infrared spectrophotometer, an electronic balance, a muffle furnace and other auxiliary materials. The experimental drugs require carbon tetrachloride, magnesium silicate, hydrochloric acid, and magnesium sulfate monohydrate. The infrared spectrophotometer requires three standard solutions of n-hexadecane, pristane and toluene. According to the standard process, it takes about 6 hours to determine the oil content, and about 24 hours to determine the water content / solid content. The test cycle is long and the data feedback is not timely. Summary of the invention

9. A method for rapid separation and determination of oil, water and solid phases of oily sludge, characterized in that: The following steps are involved: S1. Take a sludge sample with a mass of m0 and put it into a distiller, heat it to evaporate the oil and water in the sludge sample into steam; weigh the mass of the volatile oil-gas mixture as m1; S2. The condenser receives the steam and condenses it into an oil-water mixture; S3. The deoiler receives the oil-water mixture and absorbs the oil in the oil-water mixture; weighing the mass of the oil as m2; S4. The water collector receives the steam-water mixture discharged from the degreaser, separates the water in the steam-water mixture and collects it; weighs the mass of the water as m3; S5. Calculate the contents of the three phases: solid, water and oil, where the solid content is (m0-m1) / m0, the oil content is m2 / m0, and the water content is m3 / m0.

10. The method for rapid separation and determination of oil, water and solid phases of oily sludge according to claim 9, characterized in that: In step S1, the heating temperature is 400-600° C.; and / or In step S3, compressed gas is introduced into the condenser to transport the oil-water mixture and the steam-water mixture.

11. The method for rapid separation and determination of oil, water and solid phases of oily sludge according to claim 9, characterized in that: In step S1, the mass of the distiller before and after the sludge sample is volatilized is weighed by a first electronic scale, and the difference is m1; and / or In step S3, the mass of the degreaser before and after degreasing is weighed by a second electronic scale, and the difference is m2; and / or In step S4, the mass of the water collector before and after water removal and water collection is weighed by a third electronic scale, and the difference is m3.

12. The method for rapid separation and determination of oil, water and solid phases of oily sludge according to claim 9 or 11, characterized in that: In step S3 and step S4, first open the liquid outlet valve of the condenser, and then open the compressed gas inlet valve. After the compressed gas is stably discharged from the exhaust port of the water collector, close the compressed gas inlet valve, weigh the mass of the deoiler after oil removal, and weigh the mass of the water collector after water removal and water collection.
