Device for measuring content of water of crude oil and extracting asphalt

The utility model discloses a device for measuring the content of water of crude oil and extracting asphalt. The device comprises a fixed rack, a moisture measuring device and an asphaltene measuring device, wherein the moisture measuring device and the asphaltene measuring device are fixedly hung on the fixed rack in parallel; a heating device for heating the moisture measuring device or the asphaltene measuring device is arranged below the fixed rack. The device can be used for measuring the content of the water and extracting the asphaltene. By virtue of a general character that heating and cooling are required during the measurement of the content of the water and the extraction of the asphaltene, two parameters can be analyzed by virtue of the same device; the asphaltene can be cleaned by virtue of the device, so that the analysis accuracy is improved, and the human influence is eliminated; a toxic reagent is in a relatively closed state, so that the injury to an operator is greatly reduced; multiple samples can be analyzed and detected simultaneously by virtue of the device, so that the working efficiency is improved. The device has the relatively good applicability to the analysis of the content of the water of the crude oil and the asphaltene as well as has an actual application value and a wide generalization prospect.
