Description

Technical Field

[0001] This utility model belongs to the field of natural gas pipeline technology, specifically relating to a natural gas pipeline anti-blocking device. Background Technology

[0002] Natural gas pipelines are pipelines that transport natural gas (including associated gas from oil fields) from extraction sites or processing plants to urban gas distribution centers or industrial users. Also known as gas transmission pipelines, they are the primary means of transporting large quantities of natural gas over land. Natural gas pipelines account for approximately half of the world's total pipeline length.

[0003] However, the implementation of the relevant technologies revealed the following problems with the above-mentioned solutions: Existing natural gas pipelines are prone to ice blockage in winter. This is because water vapor or liquid water in natural gas combines with small molecule gases (such as CH4, C3H8, etc.) in natural gas at low temperatures, forming solid hydrates that block the pipeline. Furthermore, some hydrates in natural gas pipelines adhere to the inner wall of the pipeline or deposit in low-lying areas, gradually accumulating and blocking the pipeline. Natural gas pipelines may contain impurities, dust, oil, mud, etc., which can deposit in the pipeline and, over time, lead to blockages. Therefore, a natural gas pipeline anti-blockage device is proposed to solve the above problems. Utility Model Content

[0004] This utility model proposes a natural gas pipeline anti-blockage device, which solves the problem in related technologies that natural gas pipelines are blocked due to excessive impurities inside the natural gas.

[0007] A baffle is fixedly installed inside the filter tube, a filter element is fixedly installed inside the filter tube, and a flow channel is formed on the inner wall of the filter tube.

[0008] Preferably, an air outlet pipe is fixedly installed inside the heating tube, and an air inlet pipe is fixedly installed inside the filter tube.

[0010] Preferably, a cleaning port is fixedly installed inside the filter tube, and a fastener is installed on the internal thread of the cleaning port. A sealing cap is movably connected to one side of the cleaning port through the fastener.

[0012] Preferably, there are multiple filter elements, and the multiple filter elements are installed in a linear array inside the filter tube.

[0013] Preferably, the processor is connected to a thermometer, a temperature detector, and a heating plate via wires.

[0014] The working principle and beneficial effects of this utility model are as follows: The heating plate can heat the natural gas passing through the anti-clogging device, preventing the natural gas temperature from being too low and causing the hydrates inside the natural gas to solidify and block the natural gas pipeline. The filter element can filter the impurities inside the natural gas, preventing excessive accumulation of impurities and subsequent pipeline blockage. By movably installing the sealing cover on one side of the cleaning port, it can prevent the leakage of natural gas entering the equipment. By connecting the bottom of the thermometer to the wire, the temperature detected by the temperature detector can be displayed on the thermometer, allowing workers to know the current temperature of the pipeline. By connecting the processor to the thermometer, temperature detector, and heating plate through the wire, the processor can process the values ​​transmitted to it by the temperature detector and turn the heating plate on or off according to the temperature of the natural gas inside the pipeline.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Implementation

[0023] Please see Figure 1 -4, a natural gas pipeline anti-clogging device, comprising: a heating pipe 1 and a filter pipe 2;

[0024] A protective shell 3 is fixedly installed inside the heating tube 1, and a heating plate 4 is fixedly installed inside the protective shell 3;

[0025] A baffle 5 is fixedly installed inside the filter tube 2, a filter element 6 is fixedly installed inside the filter tube 2, and a flow channel 7 is opened on the inner wall of the filter tube 2.

[0026] The technical solution provided in this embodiment is as follows: When the device is in use, the inlet pipe 9 and the outlet pipe 8 are first connected to the natural gas pipeline. Then, the natural gas enters the filter pipe 2 through the inlet pipe 9. The natural gas is first blocked by the baffle 5. The baffle 5 is impacted by the natural gas. The solid matter inside the natural gas will fall naturally after the impact and fall to the bottom of the filter pipe 2. Then, the remaining impurities and natural gas will rise along the filter pipe 2 and be filtered by the filter element 6 to remove the impurities inside the natural gas. Then, these will flow along the guide groove 7 to the bottom of the filter pipe 2. After passing through the filter pipe 2, the natural gas will enter the heating pipe 1. The temperature detector 10 will detect the temperature of the natural gas and then transmit the value to the processor 11 and the thermometer 16 through the wire 12. The worker can know the current temperature of the natural gas pipeline through the thermometer 16. When the natural gas temperature is too low, the processor 11 will activate the heating plate 4 through the wire 12 to heat the natural gas inside the heating pipe 1 to prevent the hydrate inside the natural gas from solidifying and blocking the natural gas pipeline.

[0027] Furthermore, an exhaust pipe 8 is fixedly installed inside the heating tube 1, and an intake pipe 9 is fixedly installed inside the filter tube 2.

[0028] Specifically, by fixing the gas outlet pipe 8 inside the heating pipe 1 and fixing the gas inlet pipe 9 inside the filter pipe 2, natural gas can enter the filter pipe 2 through the gas inlet pipe 9 for filtration, be heated by the heating pipe 1, and then be discharged through the gas outlet pipe 8. This can reduce the risk of natural gas clogging the pipeline due to excessive impurities or freezing.

[0029] Furthermore, a temperature detector 10 is fixedly installed inside the heating tube 1, a processor 11 is fixedly installed inside the heating tube 1, and a wire 12 is fixedly installed inside the processor 11.

[0030] Specifically, by fixing the processor 11 inside the heating tube 1, external factors can be prevented from affecting the normal operation of the processor 11, thus preventing the processor 11 from accurately controlling the heating plate 4.

[0031] Furthermore, a cleaning port 13 is fixedly installed inside the filter tube 2, and a fastener 14 is installed inside the cleaning port 13. A sealing cap 15 is movably connected to one side of the cleaning port 13 through the fastener 14.

[0032] Specifically, by movably installing the sealing cap 15 on one side of the cleaning port 13, leakage of natural gas entering the equipment can be prevented.

[0033] Furthermore, a thermometer 16 is fixedly installed on the top of the heating tube 1, and the bottom of the thermometer 16 is connected to the wire 12.

[0034] Specifically, by connecting the bottom of the thermometer 16 to the wire 12, the temperature detected by the temperature detector 10 can be displayed on the thermometer 16, allowing the worker to know the current temperature of the pipeline.

[0035] Furthermore, there are multiple filter elements 6, and these multiple filter elements 6 are installed in a linear array inside the filter tube 2.

[0036] Specifically, by installing multiple filter elements 6 in a linear array inside the filter tube 2, the filter elements 6 can filter out impurities inside the natural gas.

[0037] Furthermore, the processor 11 is connected to the temperature gauge 16, the temperature detector 10, and the heating plate 4 via wires 12.

[0038] Specifically, by connecting the processor 11 to the thermometer 16, the temperature detector 10, and the heating plate 4 via the wire 12, the processor 11 can process the values ​​transmitted to it by the temperature detector 10 and turn the heating plate 4 on or off according to the temperature of the natural gas inside the pipeline.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
