Problems solved by technology

At present, the oil product monitoring of the above-mentioned links mainly adopts the method of manual sampling and manual testing to determine the quality of the oil product. With the development of electronic detection technology, water content analyzers are gradually used instead of manual testing to monitor the water content in the medium oil. Thus, it plays a warning role, and thus prevents the occurrence of phenomena that affect oil quality such as water mixing and dark tanks; In the scene where inferior oil is mixed, the water content analyzer cannot perform the monitoring function and cannot play a warning role, resulting in great losses for relevant users
[0003] For the testing of oil products, the two parameters of water content and density are mainly tested. The testing of wate...

Embodiment 1

[0024] Such as figure 1 As shown, an on-line measuring device for moisture content and density of the present invention includes a moisture analyzer 2 and a density meter 3, and also includes a host computer (not shown in the figure), a controller (not shown in the figure), a measuring pipeline 1 and automatic sampling device; the host computer is connected with the controller, moisture analyzer 2, density meter 3 and automatic sampling device respectively; the controller is connected with the moisture analyzer 2, density meter 3, automatic sampling device Connect respectively; Described automatic sampling device, moisture analyzer 2 and density meter 3 are respectively installed on the measuring pipeline 1, wherein, described moisture analyzer 2 and density meter 3 are arranged on the top of measuring pipeline 1, and described automatic sampling The device is arranged on the side of the measuring pipeline 1, the water content analyzer 2 and the density meter 3 are arranged op...

Embodiment 2

[0030] Such as figure 2 As shown, an on-line measuring device for moisture content and density of the present invention has the same basic structure and application as in Example 1. In order to achieve consistency in oil product measurement, specifically: the water content analyzer 2 includes a probe, and the The probe is a pipe section, and the probe is parallel to the measuring pipeline 1, so that the water content analyzer 2 can perform real-time detection along the flow direction of the oil in the measuring pipeline 1, reducing the influence of flow resistance on the instrument.

Embodiment 3

[0032] Such as image 3 As shown, an on-line measuring device for moisture content and density of the present invention has the same basic structure and application as in Example 1. In order to achieve consistency in oil product measurement, specifically: the water content analyzer 2 includes a probe, and the The probe is plug-in type, and the probe is perpendicular to the measuring pipeline 1, so that the water content analyzer 2 can penetrate deeply into the measuring pipeline 1 to detect oil products in real time.

The measure apparatus comprises a water analyzer, a densitometer, a host computer, a controller, a measure pipe and an automatic sampling device; the host computer is connected with the controller, the water analyzer, the densitometer and the automatic sampling device; the controller is connected with the water analyzer, the densitometer and the automatic sampling device; the automatic sampling device, the water analyzer and the densitometer are all installed on the measure pipe; and the water analyzer and the densitometer are arranged on the measure pipe, the automatic sampling device is arranged at the lateral side of the measure pipe, the water analyzer and the densitometer are arranged oppositely, and the automatic sampling device is opposite to the water analyzer and the densitometer and is arranged between the water analyzer and the densitometer. The apparatus is capable of realizing on-line real-time measure on an oil product and automatic sampling and storing a sample, helps to effectively solve the quality control problem of the oil product during transportation and comprehensively monitor the characteristics of the oil product, and is applicable in fields such as tank cars, pipelines, ship oil discharging and the like.

Description

technical field [0001] The invention relates to the technical field of oil-water monitoring, in particular to an on-line measuring device for water content and density and a measuring method thereof for oil quality monitoring. Background technique [0002] In pipeline oil transportation, ship unloading, tank truck unloading and other links, it is necessary to monitor the quality of oil in real time to ensure the quality of oil transportation. At present, the oil product monitoring of the above-mentioned links mainly adopts the method of manual sampling and manual testing to determine the quality of the oil product. With the development of electronic detection technology, water content analyzers are gradually used instead of manual testing to monitor the water content in the medium oil. Thus, it plays a warning role, and thus prevents the occurrence of phenomena that affect oil quality such as water mixing and dark tanks; In the scene where inferior oil is mixed, the water c...
