Description

Technical Field

[0001] This utility model relates to the field of natural gas transportation technology, and in particular to an alcohol injection device and an alcohol injection vehicle. Background Technology

[0002] With the transformation of the global energy structure and increasing environmental protection requirements, natural gas, as a clean and efficient energy source, is becoming increasingly important. Natural gas transportation, as a crucial link in the natural gas supply chain, directly impacts the stability, economy, and security of energy supply. Therefore, advanced transportation technology has become key to optimizing natural gas transportation.

[0003] Currently, natural gas is typically transported via pipelines. However, this method presents several problems. Before use, natural gas pipelines undergo pressure testing. During this process, moisture may remain in low-lying areas, bends, and other special sections of the pipeline. Natural gas also contains a certain amount of moisture. When the temperature continues to drop, this moisture can combine with other components in the natural gas to form ice blockages. This can affect the normal operation of the equipment and prevent the natural gas from being transported normally. Utility Model Content

[0012] In one embodiment, two liquid dispensing components are symmetrically arranged along the height direction.

[0013] In one embodiment, the alcohol injection unit further includes a filtration and drainage assembly, which includes a filter valve, a drain pipe, and a drain valve.

The drain pipe is connected to the liquid suction pipe, and a drain valve is disposed between the drain pipe and the liquid suction pipe. The drain valve is used to control the opening and closing of the drain pipe and the liquid suction pipe.

[0014] In one embodiment, the alcohol injection unit further includes a flow calibration component, which includes a third switching valve and a calibration column. The calibration column is connected to the suction tube and is used to monitor the flow rate of the liquid flowing into the suction tube. The third switching valve is disposed between the suction tube and the calibration column and is used to control the connection and disconnection between the suction tube and the calibration column.

[0015] In one embodiment, the liquid storage tank is provided with a level gauge and an overflow port.

This can melt the blockage in the part to be injected with alcohol that has been blocked by hydrates or ice, restore smooth flow, and lower the freezing point of the water inside, thereby providing an antifreeze effect. This greatly avoids the residual moisture in special sections such as low-lying areas, bends, and pipe bends of the part to be injected with alcohol, as well as moisture in the natural gas. When the temperature continues to drop, moisture will combine with other components in the natural gas to form ice blockage, which will affect the normal operation of the equipment and cause the natural gas to be unable to be transported normally.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] Firstly, see Figures 1-4 An embodiment of this application provides an alcohol injection device, including a base 1, a liquid storage tank 2, and an alcohol injection unit 3. The liquid storage tank 2 is fixed on the base 1 and is used to store liquid.

[0038] The alcohol injection unit 3 is fixed on the base 1. The alcohol injection unit 3 includes a liquid suction assembly 31 and an alcohol injection assembly 32. The liquid suction assembly 31 includes a liquid suction tube 311 and a first valve 312. The liquid suction tube 311 is connected to the liquid storage tank 2. The first valve 312 is located between the liquid suction tube 311 and the liquid storage tank 2. The first valve 312 is used to control the opening and closing of the liquid suction tube 311 and the liquid storage tank 2.

[0039] The alcohol injection assembly 32 includes an inlet pipe 321, an outlet pipe 322, and a discharge pipe 323. One end of the inlet pipe 321 is connected to the end of the suction pipe 311 away from the storage tank 2, and the other end is connected to the inlet of the alcohol-to-be-injected component. One end of the outlet pipe 322 is connected to the outlet of the alcohol-to-be-injected component, and the other end is connected to the discharge pipe 323.

[0040] The alcohol injection device provided in this embodiment draws liquid from the storage tank 2 through the liquid suction component 31, and then injects the liquid into the alcohol injection component 32. This dissolves the blockage in the alcohol injection component that has been blocked by hydrates or ice, restoring unobstructed flow. It also lowers the freezing point of the water inside, thus providing an antifreeze effect. This greatly avoids the accumulation of moisture in low-lying areas, bends, and other special sections of the alcohol injection component, as well as moisture in the natural gas. When the temperature continues to drop, the moisture will combine with other components in the natural gas to form ice blockage, which will affect the normal operation of the equipment and prevent the normal transportation of natural gas.

[0041] In this embodiment, the liquid is methanol or ethylene glycol. Of course, in other embodiments, the liquid can be replaced with other desired liquids, which will not be elaborated here.

[0042] When methanol or ethylene glycol is mixed with water, the resulting solution has a lower freezing point than pure water, thus preventing water from freezing or melting existing ice. Methanol molecules insert themselves between water molecules, interfering with the crystallization process and causing ice to form at a lower temperature. Similarly, ethylene glycol molecules interfere with water molecule crystallization, lowering the freezing point and preventing freezing.

[0043] like Figures 1-2 As shown, in some embodiments, the alcohol injection unit 3 further includes a venting component 33, which includes a first connecting pipe 331, a safety venting valve 332, and a venting pipe 333. One end of the first connecting pipe 331 is connected to the suction pipe 311, and the other end of the first connecting pipe 331 is connected to the venting pipe 333. A safety venting valve 332 is provided between the first connecting pipe 331 and the venting pipe 333. The safety venting valve 332 is used to control the opening and closing of the first connecting pipe 331 and the venting pipe 333.

[0044] One end of the first connecting pipe 331 is connected to the suction pipe 311, and the other end is connected to the vent pipe 333. A safety vent valve 332 is installed between the first connecting pipe 331 and the vent pipe 333. When the pressure in the pipeline is too high, the safety vent valve 332 is opened to connect the first connecting pipe 331 and the vent pipe 333, so that the liquid is discharged from the vent pipe 333, thereby reducing the pressure in the pipeline and preventing damage to the components of the alcohol injection unit 3 due to excessive pressure.

[0045] Specifically, in order to facilitate pressure monitoring in the pipeline, the venting assembly 33 includes a pressure gauge 334, which is installed on the first connecting pipe 331. The pressure gauge 334 is used to monitor the pressure in the first connecting pipe 331. The pressure gauge 334 is electrically connected to the safety venting valve 332. The pressure gauge 334 can control the safety venting valve 332 to open, so that the first connecting pipe 331 is connected to the venting pipe 333.

[0046] By installing a pressure gauge 334 on the first connecting pipe 331, the pressure inside the first connecting pipe 331 can be monitored in real time. When the pressure gauge 334 detects that the pressure inside the first connecting pipe 331 exceeds the preset pressure value, the pressure gauge 334 can control the safety vent valve 332 to open, so that the first connecting pipe 331 is connected to the vent pipe 333, allowing the liquid to be discharged from the vent pipe 333, thereby reducing the pressure inside the pipe and preventing damage to the components of the alcohol injection unit 3 due to excessive pressure.

[0047] In some embodiments, a swivel joint 335 is provided between the first connecting pipe 331 and the vent pipe 333, which facilitates the disassembly of the first connecting pipe 331 and the vent pipe 333.

[0048] like Figures 1-2 As shown, in some embodiments, two liquid dispensing components are symmetrically arranged along the height direction. The liquid dispensing components include a first liquid dispensing component and a second liquid dispensing component. The first liquid suction pipe 311 of the first liquid dispensing component and the second liquid suction pipe 311 of the second liquid dispensing component are both connected to the liquid storage tank 2. A first switching valve is provided between the first liquid suction pipe 311 and the liquid storage tank 2, and a second switching valve is provided between the second liquid suction pipe 311 and the liquid storage tank 2.

[0049] By setting up two sets of liquid outlet components, one can be used as a backup, avoiding the need for immediate repair in case one set of components fails before the alcohol injection process can begin, thus greatly improving the working efficiency of alcohol injection unit 3. In operation, the first switch valve is opened first, and the second switch valve is closed to allow the first liquid outlet component to be used for alcohol injection. If the first liquid outlet component fails, the first switch valve is closed, and the second switch valve is opened to allow the second liquid outlet component to be used for alcohol injection.

[0050] like Figures 1-2 As shown, in some embodiments, the alcohol injection unit 3 further includes a filter and sewage discharge assembly 34, which includes a filter valve 341, a sewage discharge pipe 342, and a sewage discharge valve 343. The filter valve 341 is disposed between the liquid inlet pipe 321 and the liquid suction pipe 311 and is used to filter impurities in the liquid flowing into the liquid inlet pipe 321. The sewage discharge pipe 342 is connected to the liquid suction pipe 311, and a sewage discharge valve 343 is disposed between the sewage discharge pipe 342 and the liquid suction pipe 311. The sewage discharge valve 343 is used to control the opening and closing of the sewage discharge pipe 342 and the liquid suction pipe 311.

[0051] By installing a filter valve 341 between the liquid inlet pipe 321 and the liquid suction pipe 311, solid particles, impurities or other contaminants in the liquid can be filtered to ensure the cleanliness of the liquid, thereby protecting downstream equipment or devices from contamination or damage.

[0052] In addition, by setting up a drain pipe 342, sewage, sludge, and sediment in the pipes or equipment can be removed, and air or other gases in the pipes can be expelled to prevent air blockage. Furthermore, by setting up a drain valve 343, the discharge volume can be controlled to ensure effective discharge.

[0053] like Figures 1-2 As shown, in some embodiments, the alcohol injection unit 3 further includes a flow calibration component 35, which includes a third switching valve 351 and a calibration column 352. The calibration column 352 is connected to the suction tube 311 and is used to monitor the flow rate of the liquid flowing into the suction tube 311. The third switching valve 351 is disposed between the suction tube 311 and the calibration column 352 and is used to control the on / off state between the suction tube 311 and the calibration column 352.

[0054] By setting the calibration column 352, the flow rate of the liquid can be monitored, thereby avoiding excessive or insufficient flow and allowing staff to quickly detect and adjust the flow rate. Furthermore, by installing a third switching valve 351 between the suction tube 311 and the calibration column 352, the calibration column 352 can be closed when flow monitoring is not required, thus significantly extending its service life.

[0055] In some embodiments, the alcohol injection unit 3 is further provided with a one-way valve, which is located between the liquid outlet pipe 322 and the liquid outlet of the alcohol to be injected, so as to prevent liquid from flowing back into the alcohol to be injected, thereby causing damage to the alcohol to be injected.

[0056] like Figure 1 and Figure 3 As shown, in some embodiments, the liquid storage tank 2 is provided with a liquid level gauge 21 and an overflow port 22. The liquid level gauge 21 is set along the height direction of the liquid storage tank 2 and is used to monitor the liquid level in the liquid storage tank 2. The liquid storage tank 2 has an overflow port 22, which is located above the liquid level gauge 21 along the height direction of the liquid storage tank 2.

[0057] By installing a level gauge 21 on the storage tank 2, real-time data on the liquid level inside the tank can be obtained, helping operators to monitor the liquid level. When the liquid level exceeds or falls below a set value, an alarm is triggered to prevent overflow. In addition, the overflow port 22 can prevent excessive liquid in the storage tank 2.

[0058] like Figure 1 and Figure 3 As shown, in some embodiments, a breather valve 23 is also provided on the top of the liquid storage tank 2, which is used to maintain the pressure balance inside the liquid storage tank 2.

[0059] By installing a breather valve 23 on the top of the liquid storage tank 2, it is possible to release gas and reduce pressure when the pressure inside the tank exceeds the set value; and to draw in air when a vacuum is formed inside the tank to prevent the tank from deforming.

[0060] In this embodiment, the breathing valve 23 is either a spring-loaded breathing valve 23 or a gravity-operated breathing valve 23. The specific type of breathing valve 23 used can be chosen by the operator based on actual needs, and will not be elaborated further here. Specifically, the top of the storage tank 2 is provided with an inspection port, facilitating maintenance by the operator.

[0061] In addition, the inspection port cover is equipped with a cover 24 to prevent impurities from entering the storage tank 2 through the inspection port. For example... Figure 1 and Figure 4 As shown, in some embodiments, the alcohol injection device control system 4 is electrically connected to the alcohol injection unit 3. The control system 4 can control the alcohol injection unit 3 to draw liquid from the storage tank 2 and can control the alcohol injection unit 3 to inject liquid into the part to be injected.

[0062] Specifically, the control system 4 includes a bracket 42 and a control box 41. The bracket 42 is fixed on the base 1, and the control box 41 is fixed on the bracket 42. The control box 41 is equipped with multiple switches, which are used to control the first switching valve, the second switching valve, and the third switching valve 351, as well as other valves. The principle of these switches will not be described in detail here.

[0063] In addition, a display unit is provided to display the measured values ​​of pressure gauge 334 and calibration column 352, making it convenient for operators to observe. The control box 41 is also equipped with a voltmeter and an ammeter.

[0064] Secondly, this utility model also provides an alcohol injection vehicle, including the above-mentioned alcohol injection device, as well as a vehicle body and wheels, with the base 1 fixed on the vehicle body and the wheels disposed at the bottom of the vehicle body.

[0065] By installing wheels at the bottom of the vehicle body and fixing the base 1 to the vehicle body, the entire alcohol injection device can move to different working positions as the vehicle body and wheels move, thereby greatly improving the efficiency of alcohol injection.

[0066] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
