 Such as figure 2 As shown, the device for measuring oil and / or water content in the sample provided by the present embodiment mainly includes:
 Dean-Stark water separator 1, the main body of the water separator is a vertical columnar glass tube, the top is connected to the bottom of the reflux condenser 2, and the bottom is connected to the water well 11 with metering scale; A branch pipe obliquely protrudes from the upper part of the columnar glass tube as a solvent reflux pipe. The branch pipe forms an acute angle with the wall below the columnar glass tube. in the mouth.
 The extraction device part mainly uses a solvent to extract the sample and makes the solvent and water vapor enter the Dean-Stark water separator to separate water, so as to measure the water content of the sample. The extraction device mainly includes:
 An extraction bottle 3 for accommodating the extraction solvent;
 An extraction tube 4 placed in the extraction...
 Taking oily sludge A as the sample to be tested, the device and method of Example 1 were used to extract and measure the oil and water content of the oily sludge, and the extracted oily sludge sample was dried at 115°C to make Toluene volatilizes and weighs the sample after reaching constant weight, and calculates the content of oil and water. And with the use of figure 1 The measurement results of the "Dean-Stark improved device" shown in the prior art are compared, and the measurement results are listed in the following table.
 Parallel analysis of the determination results of oil content (wet basis mass fraction) of oily sludge A
 Parallel analysis of water content (wet basis mass fraction) measurement results of oily sludge A
 In this example, the extraction rate of oil and water in the oily sludge was also recorded, and the results can be found in Figure 7 and Figure 8 , it can be seen that compared with the "De...
 Take oil sand B as the sample to be tested, utilize the device and method of embodiment 1 to extract and measure the sample, and use figure 1 The measurement results of the "Dean-Stark improved device" shown in the prior art are compared, and the measurement results are listed in the following table.
