Description

Technical Field

[0001] The invention belongs to the technical field of corrosion detection, and in particular to a device and method for detecting corrosion of a heating pipeline. Background Art

[0002] Heating pipes refer to piping systems that transport hot water or steam, and are used to provide heating, hot water and other services to buildings or industrial facilities. Heating pipes are usually exposed to the air or buried underground, so they need to have certain corrosion resistance. Corrosion resistance testing is an important part of the production process of heating pipes. It directly affects the stability and safety of the pipes during operation. Through scientific testing and measures, damage and failure of the pipes caused by corrosion can be effectively prevented, ensuring the normal operation of the heating system.

[0003] A Chinese patent application CN110618087A discloses a device for detecting corrosion resistance of a central heating pipeline. The key points of the technical solution are: comprising a detection box, a first storage box, and a second storage box, wherein an output port is arranged on one side of the upper end face of the detection box, an input port is arranged on one side of the bottom end face, and a through-joint is arranged on the box wall surface at the same height on both sides of the detection box, an elastic sealing sleeve is pressed on the inner hole wall of the through-joint, and the two ends of the through-joint extend from the box wall surface on both sides of the detection box, an electric heating panel is arranged on the inner wall surface of the detection box, the output port is connected to the output pipe, and the input port is connected to the input pipe, the output pipe is connected to the top of the first storage box, the input pipe is connected to the first drive pump, and the first drive pump is connected to the storage box.

In order to detect them, it is necessary to design a very large detection equipment, which is costly and occupies too much space.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 6As shown, a corrosion detection device for a heating pipeline according to the present invention comprises a machine tool 1, a detection ring 2, an air storage box 3 and a control console 4;

[0038] The interior of the detection ring 2 is used for the pipeline 5 to pass through; both end surfaces of the detection ring 2 are provided with sealing components; the sealing components are used to block the gap between the detection ring 2 and the pipeline 5; the surface of the detection ring 2 is fixedly connected with a pressure sensor 6 and a concentration sensor 7, and the detection ends of the pressure sensor 6 and the concentration sensor 7 extend into the interior of the detection ring 2, the pressure sensor 6 is used to detect the gas pressure, and the concentration sensor 7 is used to detect the concentration of the corrosive gas;

[0039] The gas storage box 3 is used to store corrosive gas, which may be acidic gas, alkaline gas or other gas used to detect the corrosion resistance of the pipeline 5; a delivery pump 8 is provided on the surface of the gas storage box 3; a delivery pipe 9 is connected between the delivery pump 8 and the detection ring 2, and a valve is provided on the delivery pipe 9;

[0040] A control panel is disposed on the surface of the console 4 ; an analysis module is disposed inside the console 4 ; the analysis module is used to process and analyze the detection data of the pressure sensor 6 and the concentration sensor 7 .

[0041] There are many drawbacks in the corrosion detection device of the heating pipe 5 in the prior art. For example, the technical solution disclosed in CN110618087A places the entire heating pipe 5 into a detection box and uses the corrosive gas inside the detection box to test the pipe 5. However, the diameter and length of the current heating pipe 5 are usually large. In order to detect it, it is necessary to design a very large detection equipment, which is costly and occupies too much space. In addition, this technology can only determine the corrosion resistance of the entire pipe 5, but cannot know where the corrosion resistance failure occurs in the pipe 5, so its practicality is poor.

[0042] The detection ring 2, sealing assembly, delivery pump 8, delivery pipe 9 and other components in contact with corrosive gases in the present invention are all made of corrosion-resistant materials or have undergone anti-corrosion treatment. When in use, the heating pipe 5 is passed through the detection ring 2, and the gap between the detection ring 2 and the pipe 5 is sealed by the sealing assembly, so that a relatively sealed annular space is formed between the detection ring 2 and the pipe 5. Then, the corrosive gas inside the storage box is input into the detection ring 2 through the delivery pump 8 and the delivery pipe 9, and the valve of the delivery pipe 9 is closed. At this time, the pressure sensor 6 and the concentration sensor 7 obtain a set of initial data. After a period of time, the pressure sensor 6 and the concentration sensor 7 obtain another set of data. By comparing the before and after data of the sensors by the analysis module, the corrosion resistance of the position of the pipe 5 can be determined. After that, the sealing assembly stops working, controls the pipe 5 to move horizontally for a distance, and repeats the above operation to perform corrosion detection on the remaining sections of the pipe 5 in turn.

[0043] The present invention does not need to place the entire pipeline 5 into the detection equipment when detecting corrosion, and is more suitable for heating pipelines 5 with larger sizes. The installation of the pipeline 5 is more portable, and the present invention can test different positions of the pipeline 5 section by section, which can not only determine the corrosion of the entire pipeline 5, but also know the specific corrosion position of the pipeline 5. The detection result is more precise, which is convenient for the staff to make adaptive adjustments to the production process according to the specific corrosion position.

[0044] When judging the corrosion condition of the pipeline 5, the present invention compares and analyzes the data changes before and after the pressure sensor 6 and the concentration sensor 7 through the analysis module. If the detection data of the two sensors remain unchanged, it means that the corrosion resistance of the pipeline 5 at this location is good. If the detection data of the two sensors decrease, it can be determined that the corrosion resistance of the pipeline 5 at this location is poor. The degree of corrosion of the pipeline 5 can be known through the data change value of the sensor. The larger the data change value, the worse the corrosion resistance of the pipeline 5.

[0045] In addition, while judging the corrosion condition of pipeline 5, the sealing condition of pipeline 5 can also be judged according to the sensor data. If the detection data of the two sensors remain unchanged, it means that the sealing of pipeline 5 at this location is good. If the detection data of pressure sensor 6 becomes smaller and the detection data of concentration sensor 7 remains unchanged, it can be determined that the sealing of pipeline 5 at this location is poor, and there may be local cracks or holes. The sealing degree of pipeline 5 can be known through the data change value of pressure sensor 6. The larger the data change value, the worse the sealing of pipeline 5.

[0046] The sealing assembly includes an annular groove formed at the end surface of the detection ring 2; an annular bag 10 is fixedly connected inside the annular groove; an air pump 11 is provided on the surface of the machine tool 1; an air pipe 12 is connected between the air pump 11 and the annular bag 10, and a valve is provided on the air pipe 12. During operation, the annular bag 10 is inflated by the air pump 11 and the air pipe 12, and then a pair of annular bags 10 expand inwardly and clamp the pipeline 5 to fill the gap between the two ends of the detection ring 2 and the pipeline 5, so as to achieve the sealing between the detection ring 2 and the pipeline 5, and then the valve of the air pipe 12 is closed, and when the detection is completed, the valve is opened to allow the annular bag 10 to deflate and shrink.

[0047] As a preferred embodiment of the present invention, a slide groove 13 is provided on the surface of the console 4; a slide seat 14 is slidably connected inside the slide groove 13; a connecting plate 15 is fixedly connected between the slide seat 14 and the detection ring 2; a screw rod 16 is rotatably connected inside the slide groove 13, and the screw rod 16 is driven by a motor 17; the screw rod 16 passes through the slide seat 14 and is connected to it through a screw nut pair. The screw rod 16 is controlled to rotate by the motor 17 to drive the slide seat 14 to move inside the slide groove 13, thereby adjusting the height of the detection ring 2 up and down, so as to facilitate the actual operation of the staff and facilitate the heating pipe 5 to pass through the detection ring 2. In order to improve the operation stability, a guide rod can be set on one side of the slide groove 13, and the guide rod passes through the connecting plate 15 and is slidably connected to it.

[0048] As a preferred embodiment of the present invention, brackets 18 are fixedly connected to both sides of the bottom of the detection ring 2; an adjusting roller 19 is rotatably connected between the brackets 18, and the adjusting roller 19 is driven by a second motor 20; the diameter of the adjusting roller 19 gradually increases from the middle to both ends, and the shape of the adjusting roller 19 is adapted to the pipeline 5. After the heating pipeline 5 passes through the detection ring 2, its bottom contacts the adjusting roller 19. When the pipeline 5 needs to be moved laterally, the adjusting roller 19 is controlled by the second motor 20 to rotate, driving the pipeline 5 to move laterally inside the detection ring 2, so as to perform corrosion detection on the next section of the pipeline 5, realize automatic adjustment of the pipeline 5, and do not need to manually push the pipeline 5 to move, thereby improving the automation of the device.

[0049] As a preferred embodiment of the present invention, both sides of the connecting plate 15 are fixedly connected with connecting arms 21; a group of supporting rings 22 are evenly distributed on the surface of the connecting arm 21, and the supporting rings 22 are coaxially arranged with the detection ring 2; a group of rollers 23 are evenly distributed on the circumference of the side wall surface of the supporting ring 22. By providing multiple supporting rings 22, the heating pipe 5 passes through the inside of the supporting ring 22 to support and limit the pipe 5, reduce the shaking of the pipe 5, and improve the stability of the detection process. When the pipe 5 moves horizontally, the supporting ring 22 can be used to prevent the center of gravity of the pipe 5 from shifting and becoming skewed. The pipe 5 contacts the rollers 23, and when it moves, it drives the multiple rollers 23 to rotate, so as to reduce the resistance between the pipe 5 and the supporting ring 22.

[0050] As a preferred embodiment of the present invention, a treatment box 24 is provided on the surface of the machine tool 1; the interior of the treatment box 24 is used to recover and treat corrosive gases; a recovery pump 25 is provided on the surface of the treatment box 24; a recovery pipe 26 is connected between the recovery pump 25 and the detection ring 2, and a valve is provided on the recovery pipe 26. After one detection work, the valve of the recovery pipe 26 is opened, and the corrosive gas remaining between the detection ring 2 and the pipeline 5 is pumped back to the inside of the treatment box 24 through the recovery pump 25 and the recovery pipe 26, and is centrally treated through the treatment liquid or recovery liquid inside it, and then the sealing component is controlled to stop working to prevent the corrosive gas inside the detection ring 2 from leaking out, causing air pollution and causing health effects on surrounding personnel.

[0051] As a preferred embodiment of the present invention, a guide chamber 27 is provided inside the detection ring 2; gas grooves 28 are provided on both sides of the guide chamber 27; a rotating wheel 29 is rotatably connected inside the guide chamber 27, and the rotating wheel 29 is driven by a motor; a group of blades 30 are evenly distributed on the circumference of the surface of the rotating wheel 29. During the detection process, the motor controls the rotation of the rotating wheel 29, and then under the rotation of the blades 30, the gas is sucked into the guide chamber 27 from the gas groove 28 on one side, and is thrown outward by the blades 30 through the gas groove 28 on the other side, so that the gas between the detection ring 2 and the heating pipe 5 circulates along the circumferential direction, improves the uniformity of the distribution of the corrosive gas, and allows each part of the pipe 5 to be evenly exposed to the corrosive environment, so that the detection result has more universal representative significance.

[0052] The end of the blade 30 away from the rotor 29 is rotatably connected to the guide wheel 31; the inner wall surface of the guide chamber 27 is fixedly connected to an elastic pad 32; an elastic member 33 is fixedly connected between the elastic pad 32 and the guide chamber 27; a group of elastic pads 34 are evenly distributed on the inner circumference of the detection ring 2; an elastic member 35 is fixedly connected between the elastic pad 34 and the detection ring 2; the elastic pad 32 and multiple elastic pads 34 are interconnected through a conduit 36, and the material of the elastic pad 32 and the elastic pad 34 can be elastic materials such as rubber and silicone; a group of folded springs 37 are evenly distributed on the side of the elastic pad 2 34 away from the elastic member 2 35. During the rotation, the blade 30 will intermittently use the guide wheel 31 to roll the elastic pad 1 32, and squeeze the air inside the elastic pad 1 32 into the multiple elastic pads 2 34 through the duct 36, so that the elastic pad 2 34 will continuously agitate toward the center of the detection ring 2, drive the gas around the elastic pad 2 34 to accelerate the flow, so that the gas between the detection ring 2 and the heating pipe 5 flows along the radial direction, promotes the exchange and mixing of the gases, and by setting the spring piece 37, the spring piece 37 is driven to continuously expand and contract and shake during the agitation of the elastic pad 2 34, and the spring piece 37 is used to improve the flow effect of the surrounding gas, further promote the uniform distribution of corrosive gas on the outside of the pipe 5, and improve the corrosion detection accuracy of the pipe 5.

[0054] S1: Control the screw 16 to rotate by the motor 17 to adjust the height of the detection ring 2, and then pass the heating pipe 5 through the detection ring 2 and the support ring 22, and use the sealing component to seal the gap between the detection ring 2 and the pipe 5;

[0056] S3: After a period of time, the pressure sensor 6 and the concentration sensor 7 obtain another set of data, and the analysis module compares the data before and after the two sensors to determine the corrosion resistance of the position of the pipeline 5;

[0057] S4: The residual corrosive gas between the detection ring 2 and the pipeline 5 is pumped back to the processing box 24 through the recovery pump 25 and the recovery pipe 26 for centralized processing, and then the sealing component is controlled to stop working;

[0058] S5: The adjusting roller 19 is controlled to rotate by the motor 20 to drive the pipeline 5 to move laterally inside the detection ring 2 and the support ring 22, and the above operation is repeated to perform corrosion detection on the remaining sections of the pipeline 5 in turn.
