Description

Technical field:

[0001] The utility model relates to the technical field of gas pipelines, in particular to a gas pipeline capable of preventing coking and blockage. Background technology:

[0002] During the use of the gas generator, the gas it produces will carry a large amount of coal ash, which will be brought into the pipeline system as the gas flows. At the same time, the gas also contains a large amount of tar, which is easy to deposit in the gas pipeline, causing internal blockage. This blockage not only hinders the normal transportation of gas, but also significantly increases the resistance during the transportation process. As the blockage worsens, the gas transportation efficiency will gradually decrease, and in severe cases it may even cause the paralysis of the entire gas transportation system. Utility model content:

[0003] To this end, the present invention provides a gas pipeline that prevents coking and blockage, overcoming the existing problem of the gas produced by the gas generator carrying a large amount of coal ash. This coal ash is carried into the pipeline system along with the gas flow. The gas also contains a large amount of tar. Tar easily accumulates in the gas pipeline, causing internal blockage. This blockage not only hinders the normal delivery of gas but also significantly increases the resistance during the delivery process. As the blockage worsens, the gas delivery efficiency gradually decreases, and in severe cases, it can even paralyze the entire gas delivery system.

[0004] The utility model is implemented by the following technical solutions:

[0005] A gas pipeline for preventing coking and blockage includes a gas pipeline, wherein the diameter of the gas pipeline is arranged to decrease sequentially from the gas input end to the gas output end, and the gas pipeline is fixedly sheathed with a heat insulation device, which can prevent the gas pipeline from reducing heat dissipation during the gas transportation process.

[0006] Preferably, auxiliary devices are fixed in the gas pipeline at equal intervals from the gas input end to the gas output end, and the auxiliary devices can assist in collecting tar and impurities.

[0007] Preferably, the auxiliary device includes a plurality of collection tanks, each of which is fixedly arranged at the bottom of the gas pipeline and is connected to the gas pipeline. A vibration component is fixed between adjacent collection tanks, and the vibration component can assist in vibrating tar and impurities into the collection tank.

[0008] Preferably, the vibration assembly includes a vibration plate, both ends of which are fixedly connected to the collection tank via elastic plates, a vibrator is fixed to the outer side of the vibration plate, and the cross-section of the vibration plate is in an inverted V shape.

[0009] Preferably, the bottom of the collecting trough is movably connected to a discharge plate, one end of the discharge plate is hinged to one side of the bottom of the collecting trough, and the other end is fixedly connected to the other side of the bottom of the collecting trough by bolts.

[0010] Preferably, the insulation device includes an insulation sleeve, which is made of insulation material and is fixedly sleeved on the outside of the gas pipeline.

[0012] Preferably, a thermal insulation sleeve is provided through the bottom of the collecting tank.

[0013] Advantages of the present invention: By adopting a tapered pipe to transport gas, the speed of the gas gradually increases when passing through the gas pipe. According to the principles of fluid mechanics, the increase in flow rate helps to reduce the deposition of tar and other impurities carried in the gas on the inner wall of the pipe, because a higher flow rate can provide greater kinetic energy, helping to carry these substances through the pipe instead of allowing them to settle on the inner wall, reducing the chance of blockage and ensuring the normal operation of the entire gas transportation system.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1 、 Figure 2 As shown, a gas pipeline for preventing coking and blockage includes a gas pipeline 1. The diameter of the gas pipeline 1 is set to decrease from the gas input end to the gas output end. The gas pipeline 1 is fixedly sheathed with an insulation device, which can prevent the gas pipeline from reducing heat dissipation during gas transportation.

[0020] Specifically, the diameter of the gas pipeline 1 is set to decrease in sequence from the gas input end to the gas output end, that is, a tapered pipeline is used to transport gas, so that the speed of the gas gradually increases when passing through the gas pipeline 1. According to the principles of fluid mechanics, the increase in flow rate helps to reduce the deposition of tar and other impurities carried in the gas on the inner wall of the pipeline, because a higher flow rate can provide greater kinetic energy, helping to carry these substances through the pipeline instead of allowing them to settle on the inner wall, reducing the chance of blockage and ensuring the normal operation of the entire gas transportation system.

[0021] Auxiliary devices are fixed in the gas pipeline 1 at equal intervals from the gas input end to the gas output end. The auxiliary devices can assist in collecting tar and other impurities.

[0022] Specifically, tar and other impurities can be collected to a certain extent during the gas transportation process without affecting the normal gas transportation function of the gas pipeline 1.

[0023] The auxiliary device includes multiple collection tanks 2, each collection tank 2 is fixedly arranged at the bottom of the gas pipeline 1 and is connected to the gas pipeline 1. A vibration component is fixed between adjacent collection tanks 2, and the vibration component can assist tar and other impurities to be vibrated into the collection tank 2.

[0024] Specifically, each collection tank 2 is connected to the gas pipeline 1 to ensure that the tar and other impurities in the gas flowing through the gas pipeline can enter the collection tank 2. At the same time, in order to improve the collection efficiency, a vibration component is installed between adjacent collection tanks 2. The vibration component generates vibration to help loosen the tar and other impurities attached to the inner wall of the gas pipeline 1, causing them to fall off and fall into the collection tank 2.

[0025] The vibration assembly includes a vibration plate 3, both ends of which are fixedly connected to the collection tank 2 through elastic plates 4. A vibrator 5 is fixed to the outer side of the vibration plate 3, and the cross section of the vibration plate 3 is an inverted V-shaped arrangement.

[0026] Specifically, because the two ends of the vibration plate 3 are fixedly connected to the collection tank 2 through the elastic plates 4, the vibration plate 3 is driven to vibrate by the vibrator 5, so that the tar and other impurities attached to the vibration plate 3 are vibrated and loosened. At the same time, because the cross-section of the vibration plate 3 is an inverted V shape, this helps the loosened tar and other impurities fall into the collection tank 2.

[0027] The bottom of the collecting tank 2 is movably connected to a discharge plate 6 , one end of the discharge plate 6 is hinged to one side of the bottom of the collecting tank 2 , and the other end is fixedly connected to the other side of the bottom of the collecting tank 2 by bolts.

[0028] Specifically, the discharge plate 6 is movably connected to the bottom of the collecting tank 2, so that the discharge plate 6 can move to a certain extent at the bottom of the collecting tank 2, thereby facilitating the unloading and cleaning of the collected tar and other impurities.

[0029] The insulation device includes an insulation sleeve 7, which is made of insulation material. The insulation sleeve 7 is fixedly sleeved on the outside of the gas pipeline 1. A plurality of electric heating rods 8 are arranged in sequence between the inner wall of the insulation sleeve 7 and the outer wall of the gas pipeline 1, and the electric heating rods 8 are fixedly connected to the inner wall of the insulation sleeve 7.

[0030] Specifically, heat is generated by the electric heating rod 8, and the insulation sleeve is fixedly sleeved on the outside of the gas pipe to form a closed space. When the electric heating rod 8 is energized, heat is transferred to the space between the insulation sleeve and the gas pipe, so that the temperature in the gas pipe 1 can be maintained at a certain temperature. Moreover, since the insulation sleeve 7 is made of insulation material, it has good insulation performance and can effectively retain heat and reduce heat loss to the external environment, thereby reducing heat dissipation and precipitation and coking during gas transportation.

[0031] A plurality of battery packs 9 are fixed at equal intervals on the outer wall of the heat preservation sleeve 7. The battery packs 9 are electrically connected to the vibrator 5 and the electric heating rod 8 respectively. A high temperature protection cover is fixed to the outer side of the vibrator 5. The bottom of the collection tank 2 is provided with the heat preservation sleeve 7.

[0032] Actual working process: The diameter of the gas pipeline 1 is set to decrease from the gas input end to the gas output end, forming a tapered pipeline, so that the gas flow rate gradually increases. According to the principles of fluid mechanics, the increase in flow rate helps to reduce the deposition of tar and other impurities carried by the gas on the inner wall of the pipeline, reducing the probability of blockage;

[0033] A vibration assembly is fixed between adjacent collection tanks 2. The vibration assembly helps tar and other impurities fall off and fall into the collection tank 2 through vibration. At the same time, the cross-section of the vibration plate 3 is in an inverted V shape, which helps the loosened tar and other impurities fall into the collection tank 2.

[0034] When the electric heating rod 8 is energized, the heat is transferred to the space between the insulation sleeve and the gas pipeline, maintaining the temperature in the gas pipeline 1, reducing heat loss and precipitation and coking;

[0035] A heat-insulating sleeve 7 is provided at the bottom of the collecting tank 2, and a discharge plate 6 is movably connected to the bottom of the collecting tank 2 to facilitate unloading and cleaning of the collected tar and other impurities.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
