Description

Technical Field

[0001] This utility model belongs to the field of mid-infrared spectroscopy detection technology for oil, specifically relating to a bubble diversion and stabilization device for mid-infrared online detection. Background Technology

[0002] In the detection of acid value and trace moisture in lubricating oil, infrared spectrometers are often used to analyze lubricating oil samples. By detecting the absorption and reflection of infrared radiation of a specific wavelength by the lubricating oil sample, its molecular structure and composition can be analyzed. However, due to the influence of the optical characteristics of bubbles, they can easily be misjudged as valid values, leading to deviations in the acid value and trace moisture detection results.

[0003] Currently, in the process of online infrared spectroscopy detection of acid value and trace moisture in oil, negative pressure exhaust and flow channel optimization are used to solve the influence of air bubbles on the detection results. The negative pressure method can eliminate air bubbles in the oil sample, but incomplete elimination of air bubbles will lead to large deviations in the measurement results. Moreover, the structure of the negative pressure device combined with the flow channel optimization is too complicated and is not suitable for the installation and implementation of online mid-infrared spectroscopy detection sensors. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mid-infrared online detection bubble drainage and stabilization device, comprising: Main flow pipe is used to transport the oil to be tested; The main flow heating zone, located at the front of the main flow pipe, is used to heat the flowing oil. The main flow heating zone is a heating sleeve wrapped around the front of the main flow pipe. The inclined inlet is downstream of the heating sleeve and before the detection zone; The bypass channel connected to the inclined inlet is used to guide the separated bubbles out.

[0008] As a further embodiment of this invention, the heating sleeve is a temperature-controllable heating structure.

[0009] As a further embodiment of this invention, the outlet of the bypass channel merges with the downstream of the main flow channel, so that the separated bubbles can be incorporated into the main liquid flow.

[0010] As a further embodiment of this invention, the inclined inlet is located above the main flow channel to guide the rising air bubbles into the bypass channel.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-2 This utility model provides a mid-infrared online detection bubble drainage and stabilization device, comprising: Main flow channel 108 is used to transport the oil to be tested; main flow channel heating zone 202 is set at the front of the main flow channel 108 to heat the flowing oil, and the main flow channel heating zone 202 is a heating sleeve wrapped around the front of the main flow channel 108; a sloped inlet is located downstream of the heating sleeve and before the detection zone 107; a bypass channel 206 connected to the sloped inlet is used to guide the separation bubbles 205 to be discharged; an ultrasonic generator integrated inside the main flow channel heating zone 202 is used to apply ultrasonic oscillation to the heated oil; By heating the liquid in the front section of the main flow pipe 108 through the heating sleeve, the bubbles 103 in the oil sample are intensified to overflow, forming separation bubbles 205. Since the density of separation bubbles 205 is less than that of the liquid, they are very easy to float to the surface when heated. The ultrasonic device installed inside the heating sleeve can simultaneously perform ultrasonic oscillation on the heated oil liquid, which helps to expel the separation bubbles 205. This effectively solves the problem of the influence of bubbles 103 in the oil sample on the results of mid-infrared detection, reduces detection operation failures, and lowers operation and maintenance costs.

[0019] The ultrasonic generator is model US-1500. Its structure and principle can be learned by our technicians through technical manuals or conventional experimental methods, and will not be elaborated on here.

[0020] In this invention, the inclined inlet is located above the main flow pipe 108 at an angle of 45°, and is used to introduce the floating separation bubbles 205 into the bypass flow channel 206. The inner wall of the bypass flow channel 206 is a smooth surface and has no step structure, which can minimize the retention and adhesion of the separation bubbles 205 during the flow process and ensure that the separation bubbles 205 can be smoothly discharged from the system along the bypass flow channel 206. Meanwhile, the 45° inclined inlet design, combined with the smooth inner wall of the bypass channel 206, forms a highly efficient bubble drainage mechanism. This mechanism works in conjunction with the heating and ultrasonic oscillation devices of the main flow channel 108. From heating to promote the overflow of bubbles 103 in the oil sample, to ultrasonic oscillation to accelerate the separation of bubbles 103 in the oil sample, to inclined guidance and smooth channel-assisted discharge, the removal efficiency of bubbles 103 in the oil sample is improved in multiple dimensions. This further ensures the purity of the oil in the mid-infrared detection zone 107, and significantly improves the accuracy and stability of the detection results.

[0021] The heating sleeve is a temperature-controllable heating structure, which is a closed-loop temperature control system consisting of a heating element, a temperature sensor, and a control module. The heating element is evenly wound around the outer wall of the sleeve, which can quickly transfer heat to the oil in the main flow pipe 108. The temperature sensor monitors the oil temperature in the sleeve in real time and feeds the data back to the control module. The control module automatically adjusts the heating power according to the deviation between the set temperature and the actual temperature, so that the oil temperature is stabilized within the preset range. This avoids the oil properties from changing due to excessively high temperature or the overflow effect of bubbles 103 in the oil sample due to excessively low temperature, thereby achieving precise control of the heating process. The heating element can be a resistance wire made of nickel-chromium alloy.

[0022] The outlet of the bypass channel 206 merges with the downstream of the main flow channel 108 to separate the bubbles 205 and allow them to flow into the main liquid flow, thus preventing the separated bubbles 205 from accumulating in the system and forming air blockages.

[0023] It should be noted that: Figure 1 The principle of the infrared sensor in this application for detecting the acid value and trace moisture content of lubricating oil includes an infrared light source 101 and a photoelectric converter 105, wherein... Figure 1 and Figure 2 In the oil sample, bubbles 103, liquid flow direction 104, oil and water mixture 106, oil-bubble mixed flow 201, bubble trajectory direction 203, and main oil flow direction 204 are all used to aid understanding. The specific principles are as follows: Infrared light source 101 emits collimated light beam 102 which shines on the main flow pipe 108 to detect the liquid in the main flow pipe 108. The collimated light beam 102 passes through the liquid and shines on the photoelectric converter 105. The photoelectric converter 105 converts the light intensity change into voltage pulses, thereby counting and classifying them to realize the detection of lubricating oil acid value and trace moisture content.

[0024] The working principle of this invention is as follows: When liquid flows in the main flow channel 108, it generates an oil-bubble mixture flow 201. When the oil-bubble mixture flow 201 passes through the heating zone 202 of the main flow channel, it is heated and vibrated by the heating sleeve and ultrasonic device, which intensifies the overflow of bubbles 103 in the oil sample. Separated bubbles 205 move upward in the liquid and enter the bypass channel 206 after passing through the inclined inlet. Meanwhile, the oil and water mixture 106 in the liquid in the main flow channel 108 enters the detection zone 107. The separated bubbles 205 will flow back into the main flow channel 108 from the bypass channel 206. Since the bubbles 103 in the oil sample no longer pass through the detection zone 107, the number of bubbles 103 in the oil sample in the detection zone 107 is greatly reduced, effectively solving the problem of the influence of bubbles 103 in the oil sample on the results of mid-infrared spectroscopy detection, reducing detection operation failures, and lowering operation and maintenance costs.
