Description

Technical Field

[0001] The utility model relates to the technical field of extraction devices, in particular to a device for extracting petroleum hydrocarbons in water. Background Art

[0002] Petroleum hydrocarbons in water need to be extracted. The extraction is divided into production extraction and laboratory extraction. In laboratory extraction, transfer all samples to a 2L separatory funnel, measure 60ml of dichloromethane (5.1) to wash the sample bottle, and then transfer all to the separatory funnel. Vibrate and extract for 5min (pay attention to degassing), let it stand for 10min, wait for the two phases to separate, and collect the lower organic phase. Add 60ml of dichloromethane, repeat the above operation, and combine the extracts. Dehydrate the extract with anhydrous sodium sulfate, transfer all the water phase to a 1000ml measuring cylinder, measure the sample volume and record it.

[0003] The Chinese patent authorization announcement number CN218896077U discloses a device for dewatering and purifying petroleum hydrocarbon extracts. The patent arranges a dewatering pipe and a purification column on a slide and a fixed frame of a lifting frame respectively, thereby realizing the adjustment of the height of the dewatering pipe relative to the purification column. In addition, the dewatering pipe and the purification column are connected by a connecting pipe, and a screening filter is arranged at the connection of the connecting pipe. When the height of the dewatering pipe is lower than the height of the purification column, the extract is dewatered in the dewatering pipe. After the dewatering is completed, the height of the dewatering pipe is raised to be higher than the height of the purification column, so that the dewatered sample can enter the purification column through the connecting pipe and the screening filter, and is purified by the purification column, thereby meeting the dewatering and purification requirements of the petroleum hydrocarbon extract. At the same time, the sample is completely transferred between the dewatering pipe and the purification column in the pipeline, thereby avoiding the problem of spillage that is easy to occur during the pouring process, improving the recovery rate of petroleum hydrocarbons, and ensuring the accuracy of the test results.

[0004] The above patent provides a petroleum hydrocarbon extraction device for laboratory use. The petroleum hydrocarbon extraction device of this structure does not have a separatory funnel. When using a separatory funnel for extraction, it is necessary to drive the liquid inside the separatory funnel to flip and oscillate back and forth. The existing extraction device cannot drive the separatory funnel to flip and oscillate, which is not conducive to efficient extraction of petroleum hydrocarbons. Utility Model Content
