Embodiment Construction

[0038] In order to have a clearer understanding of the technical solutions, objectives and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings. Wherein, the use of the adjective or adverbial modifiers "top" and "bottom", "inner" and "outer" is only to facilitate relative reference between groups of terms and does not describe any specific relationship to the modified term. Orientation constraints. In addition, the terms "first", "second", "third" and so on are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the number of indicated technical features, thus, limiting A feature with "first", "second", "third", etc. may expressly or implicitly include one or more of that feature.

[0039] Such as figure 1 As shown, the present invention provides a multi-component thermal fluid residual ox...

Abstract

The invention provides a multi-element thermal fluid residual oxygen detection device which comprises a detection pipeline, and a cooling decompression separation assembly, a filter and an oxygen content analyzer are sequentially arranged on the detection pipeline. The cooling decompression separation assembly comprises a first-stage cooler, a first-stage decompression separation device, a second-stage cooler, a second-stage decompression separation device and a third-stage decompression separation device which are communicated in sequence, wherein the third-stage decompression separation device is communicated with the filter. According to the device, the multi-element thermal fluid can be converted into the gas to be detected with the dryness of 100% under the conditions of normal temperature and normal pressure, and the gas to be detected can be directly introduced into the oxygen content analyzer after being filtered, so that the content of the residual oxygen in the multi-element thermal fluid detected by the oxygen content analyzer is more accurate; therefore, in the multi-element thermal fluid injection process, protection of an injection pipeline and an oil well pipe column is guaranteed.

Description

technical field [0001] The invention relates to the technical field of residual oxygen detection, in particular to a multi-component thermal fluid residual oxygen detection device. Background technique [0002] The traditional residual oxygen detection device can only detect gas with a dryness of 100%, and cannot detect the multi-phase mixed gas of the multi-element thermal fluid, and the zirconia head of the traditional residual oxygen detection device is in contact with the moisture in the multi-element thermal fluid After that, it will become invalid and valid data cannot be detected. Contents of the invention [0003] The object of the present invention is to provide a multi-element thermal fluid residual oxygen detection device capable of detecting the residual oxygen content in the multi-element thermal fluid. [0004] In order to achieve the above object, the present invention provides a multi-element thermal fluid residual oxygen detection device, which includes a...
