Embodiment 1

[0018] like figure 1 Shown is the oilfield sludge multi-component extraction device of the present invention, comprising an extraction bottle 1 containing an extraction solvent at the bottom, a heating device is provided below the extraction bottle 1, and a thermometer 2 is also provided in the extraction bottle 1 for To measure the heating temperature of the solvent, the top of the extraction bottle 1 is provided with an extraction tube 4 for holding the solute. The bottom of the extraction tube 4 is closed and the upper part is open. Capillary 3, a bypass pipe 5 is provided between the upper mouth of the extraction bottle 1 and the upper part of the extraction pipe 4. The bypass pipe 5 extends upward to the upper end of the extraction pipe 4 and communicates with it laterally. The water separator, the water separator includes the water dividing cylinder 7 on the lower side and the branch pipe 6 bypassing the water dividing cylinder 7 above, the outlet below the branch pipe 6...

Embodiment 2

[0023] The method for recovering moisture in the drier in the oilfield sludge multi-component extraction device using the above-mentioned moisture recovery device, the specific process is: the bottom of the drier 9 after extraction and separation is connected to the first opening of the three-necked flask 10, and the drier The top of 9 is connected with the small test tube 16 that anhydrous calcium chloride is housed by air outlet pipe 13, elastic silica gel transition pipe 14, because anhydrous calcium chloride has very strong water absorption performance, in the inventive method, dry in drier 9 The consumption of agent is generally 40 ~ 60 grams, and the weight of calcium chloride in the small test tube 16 is 5 ~ 6 grams; Contain cooling liquid inside; connect the nitrogen gas input pipe 11, pass nitrogen gas into the three-necked flask 10 at 0.3 L / min, start the constant temperature heating device 11 at the same time, and adjust the heating temperature to 105~110° to heat th...

Abstract

The invention relates to the technology of oily sludge component testing and particularly relates to an oil field sludge multi-component extraction device and method for recycling water in a dryer thereof. The oil field sludge multi-component extraction device comprises an extraction bottle for holding an extraction solvent at the bottom, wherein a heating device is arranged below the extraction bottle; an extraction pipe for holding a solute is arranged above the extraction bottle, and the bottom of the extraction pipe is closed while the upper part is open; the bottom side wall of the extraction pipe is communicated with a capillary pipe extending into the extraction bottle; a bypass pipe is arranged between the top opening of the extraction bottle and the upper part of the extraction pipe; the bypass pipe extends upward to the upper end of the extraction pipe and is laterally communicated with the extraction pipe; a water distributor is connected above the extraction pipe and comprises a water distribution measuring cylinder on the lower side and a branch pipe laterally bypassed above the water distribution measuring cylinder; an outlet below the branch pipe extends into the extraction pipe; the upper part of the water distribution measuring cylinder is connected with a condensing pipe; the top of the condensing pipe is communicated with a dryer; and a silica-gel drying agent is arranged in the dryer.

Description

technical field [0001] The invention relates to an oily sludge component testing technology, in particular to a multi-component extracting device for oilfield sludge and a water recovery method in a drier. Background technique [0002] my country's petrochemical industry produces a large amount of oily sludge every year, and the output is still increasing year by year. Oily sludge is the main pollutant in the "National Hazardous Waste List". If it is discharged directly without treatment, it will damage the surrounding environment and production. Different regions have different impacts, and it is also a waste of resources. Therefore, it is very important to accurately analyze the water content, oil content, slag content and the content of asphaltene, saturated, aromatic, paraffin and colloid in oily sludge, which is an effective method for oily sludge. Recycling and harmless research premise. [0003] At present, the Soxhlet extraction method is relatively mature for testi...
