Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a gas pipeline liquid accumulation collection device for a torch pilot light and a torch pilot light. Background Art

[0002] In the high-sulfur natural gas gathering and transportation process, the venting flare system is one of the important facilities for HSE management. It is mainly used for emergency venting and maintenance venting of natural gas gathering and transportation stations. When equipment or pipelines have overpressure, leakage or abnormality during the production process, the acid gas cannot be discharged directly. It is necessary to discharge the high-sulfur natural gas in the pipeline or equipment to the flare through the venting pipeline in time to avoid direct discharge of natural gas in the equipment and pipelines in the gathering and transportation station into the atmosphere during venting, causing pollution to the environment and even direct harm to personnel. The venting flare is an important safety line for high-sulfur gas production, gathering and transportation, so the flare must be kept in a normal burning state 24 hours a day.

[0003] There are four gas pipelines for each flare in a gas field in southwest my country, extending from the ground to 60-120 meters in the air to keep the gas supply burning. In summer, there is a lot of rain, which causes rainwater to flow from the top of the flare along the opening of the flare tube into the pipeline and accumulate at the bottom of the flare pipeline. If it is not drained in time, more and more water will accumulate in the pipeline, eventually blocking the flare fuel gas supply and causing the flare to go out. At the same time, long-term accumulation of liquid in the pipeline also increases the corrosion rate in the pipeline. Utility Model Content

[0004] The utility model aims to solve the problem that rainwater and other liquids flow into the pipeline from the top of the torch along the tube mouth of the pilot lamp and accumulate at the bottom of the torch pipeline, thereby blocking the torch fuel gas supply, extinguishing the torch, and increasing the corrosion rate in the pipeline. A gas pipeline liquid collection device for a torch pilot lamp and a torch pilot lamp are provided.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model provides a gas pipeline liquid collection device for a torch light, because the gas outlet pipeline and the light pipeline are in a vertical relationship, which can effectively prevent rainwater flowing down the light pipeline from directly entering the gas outlet pipeline, causing water accumulation in the gas outlet pipeline, and effectively prevents problems such as torch flameout and pipeline corrosion caused by water accumulation in the pipeline. Since a drainage pipeline is also extended at the connection between the gas outlet pipeline and the light pipeline, the drainage pipeline can guide rainwater flowing down the light pipeline into the cylinder body, and prevent water from entering the gas outlet pipeline or the gas inlet pipeline. A drainage pipeline is provided at the bottom of the cylinder body, and the accumulated liquid in the cylinder body can be conveniently discharged through the drainage pipeline, thereby ensuring that the airflow channel of the torch light pipeline is unobstructed and the torch burns normally.

[0008] Optionally, the air intake line is installed on the upper part of the cylinder.

[0009] The air intake pipeline is set at the upper part of the cylinder.

[0010] Optionally, an end cap is detachably mounted on the bottom of the cylinder, and the drainage line is mounted on the end cap.

[0011] A detachable end cover is provided at the bottom of the cylinder, and a drainage pipeline is installed on the end cover.

[0012] Optionally, the drainage pipeline is located on a side of the top of the cylinder away from the air inlet pipeline, and the air outlet pipeline is located on a side of the top of the cylinder close to the air inlet pipeline.

The first mist catching net divides the cylinder into at least two parts.

[0013] With this structural setting, the cylinder is divided into two parts by the first mist catching net. When the gas on the side of the drainage pipeline in the cylinder passes through the mist catching net, the droplets carried by the gas are captured by the mist catching net and retained on the side of the drainage pipeline, which can further avoid corrosion of the pipeline by accumulated liquid.

[0015] With this structural arrangement, the first mist catching net divides the cylinder into two parts, and the second mist catching net further divides the cylinder into four parts. With this arrangement, when the gas on the side of the drainage pipeline in the cylinder passes through the mist catching net, the droplets carried by the gas are captured by the mist catching net and retained on the side of the drainage pipeline. When the gas at the bottom of the cylinder flows upward, the second mist catching net can further capture the droplets carried by the gas, and can further avoid the corrosion of the pipeline by the accumulated liquid. At the same time, the design of the double mist catching net can further improve the collection efficiency of water mist and fine droplets.

[0016] Optionally, the drainage pipeline is located on a side of the top of the cylinder away from the air inlet pipeline, and the air outlet pipeline is located on a side of the top of the cylinder close to the air inlet pipeline, and also includes a first mist catching net and a second mist catching net, the first mist catching net is located between the drainage pipeline and the air outlet pipeline, one end of the first mist catching net is installed on the top of the cylinder, the other end of the first mist catching net extends to the bottom of the cylinder, one end of the first mist catching net extending toward the bottom of the cylinder extends out of the second mist catching net, the second mist catching net extends toward one side of the air inlet pipeline, the edge of the second mist catching net is in contact with the side wall of the cylinder, and the first mist catching net and the second mist catching net divide the cylinder into at least two parts.

[0017] With this structural setting, the first mist catching net and the second mist catching net are connected to form a structure similar to an "L" shape, and the second mist catching net extends toward one side of the air inlet pipeline. The mist catching net with such a structure can divide the cylinder into two irregular parts. The gas on the side where the drainage pipeline in the cylinder is located and the bottom of the cylinder carry droplets when entering the side where the air inlet is located, and the droplets are captured by the mist catching net and retained on one side of the drainage pipe. This "L" shaped structure reduces the amount of mist catching net used and saves the production cost of the accumulated liquid collection device.

[0018] Optionally, the first mist catching net is arranged on the axis of the cylinder, and the second mist catching net is a semicircular structure.

[0019] The second mist catching net is set to a semicircular structure, which cooperates with the first mist catching net to effectively divide the space and achieve a better effect in collecting droplets.

[0020] Optionally, the first mist catching net is perpendicular to the second mist catching net.

[0021] The first mist catching net is arranged perpendicular to the second mist catching net, which is convenient for actual production.

[0022] Optionally, the air intake pipeline, the liquid discharge pipeline, and the drainage pipeline are all installed with control valves, and the control valves are used to control the opening and closing of the pipelines.

[0023] Corresponding control valves are installed in the air intake pipeline, liquid discharge pipeline and drainage pipeline, which can accurately control the opening and closing of each pipeline according to actual needs, thereby improving the management ability of the medium in the pipeline.

Since a drainage pipeline is also extended at the connection between the gas outlet pipeline and the light pipeline, the drainage pipeline can guide rainwater flowing down the light pipeline into the cylinder body, preventing water from entering the gas outlet pipeline or the gas inlet pipeline. A drainage pipeline is provided at the bottom of the cylinder body, and the accumulated liquid in the cylinder body can be conveniently discharged through the drainage pipeline, thereby ensuring that the airflow channel of the torch light pipeline is unobstructed and the torch burns normally.

[0031] 5. The gas pipeline liquid accumulation collection device for the torch permanent lamp provided by the utility model can be provided with a first mist catching net to divide the cylinder into two, and a further second mist catching net to divide the cylinder into four.

[0045] Example 1

[0046] like Figure 1 As shown, a gas pipeline liquid collection device for a torch light includes a cylinder 1. It is foreseeable that the cylinder 1 can be a cylindrical or rectangular structure with a cavity inside. The side wall of the cylinder 1 is installed with an air intake pipeline 2. Figure 1 As shown, the air intake pipeline 2 is installed at a position slightly above the side wall of the cylinder 1. The air intake pipeline 2 is set at the upper part of the cylinder 1. After the fuel gas enters the cylinder 1 through the air intake pipeline 2, the flow rate is instantly reduced, and the liquid carrying capacity is reduced, which is conducive to separating the water vapor carried by the fuel gas itself. At the same time, it can also keep the accumulated liquid at the bottom of the cylinder 1 away from the pipeline, reducing the corrosion of the pipeline by the accumulated liquid. A control valve 8 is also installed on the air intake pipeline 2. The control valve 8 is an air inlet control valve here, which is used to control the opening and closing of the air intake pipeline 2.

[0047] The bottom of the cylinder 1 is provided with a liquid discharge line 3. Specifically, the bottom of the cylinder 1 is provided with a detachable end cap 6, which can be detachably connected by means of threads or snaps. A detachable end cap 6 is provided at the bottom of the cylinder 1, and the liquid discharge line 3 is installed on the end cap 6. The detachable structure facilitates the inspection, cleaning and maintenance of the liquid discharge line 3, the end cap 6 and the inside of the cylinder 1, thereby improving the maintainability of the liquid accumulation collection device. At the same time, the end cap 6 can also be used to collect liquid accumulation. The liquid discharge line 3 can be installed on the end cap 6, and a control valve 8 is also installed on the liquid discharge line 3. The control valve 8 is a liquid discharge port control valve here, which is used to control the opening and closing of the liquid discharge line 3.

[0048] A drainage pipeline 4 and an air outlet pipeline 5 are installed on the top of the cylinder 1. Figure 1 As shown, the drainage pipeline 4 is located at the top of the cylinder 1 on the side away from the air inlet pipeline 2, and the air outlet pipeline 5 is located at the top of the cylinder 1 on the side close to the air inlet pipeline 2. The air outlet pipeline 5 can be an elbow pipeline, for example Figure 1 The air outlet pipeline 5 shown in the figure can be divided into a first air outlet pipeline 51 and a second air outlet pipeline 52. The first air outlet pipeline 51 and the second air outlet pipeline 52 can be split or integrated. A control valve 8 is also installed on the first air outlet pipeline 51. The control valve 8 is an air outlet control valve here, which is used to control the opening and closing of the air outlet pipeline 5. Figure 1 As shown, the first air outlet line 51 extends upward from the top of the cylinder 1, and the second air outlet line 52 turns left 90 degrees from the first air outlet line 51 and connects with the ever-burning lamp line 100, that is, the ever-burning lamp line 100 and the first air outlet line 51 are approximately parallel, and the second air outlet line 52 connects the ever-burning lamp line 100 and the first air outlet line 51, and is perpendicular to the two, that is, the air outlet line 5 is vertically connected with the ever-burning lamp line 100. Figure 1 As shown, a drainage line 4 is also extended from the connection point between the pilot lamp line 100 and the second gas outlet line 52. Specifically, the drainage line 4 extends downward to the cylinder 1. The extension direction of the drainage line 4 is parallel to the extension direction of the pilot lamp line 100. The drainage line 4 connects the pilot lamp line 100 and the cylinder 1. The connection point between the drainage line 4, the pilot lamp line 100 and the second gas outlet line 52 forms a similar three-way structure. A control valve 8 is also installed on the drainage line 4. The control valve 8 is a liquid inlet control valve here, which is used to control the opening and closing of the drainage line 4, and then control the liquid in the pilot lamp line 100 to flow into the cylinder 1.

[0049] Further Figure 1 As shown, the drainage pipeline 4 is located at the top of the cylinder 1 on a side away from the air inlet pipeline 2, and the air outlet pipeline 5 is located at the top of the cylinder 1 on a side close to the air inlet pipeline 2. A first mist catching net 71 is provided in the cylinder 1. The first mist catching net 71 is specifically located between the drainage pipeline 4 and the air outlet pipeline 5. One end of the first mist catching net 71 is installed at the top of the cylinder 1, and the other end of the first mist catching net 71 is installed at the bottom of the cylinder 1. Figure 1 As shown, the first mist catcher 71 divides the cylinder 1 into two parts, namely, the side where the drainage pipeline 4 is located and the side where the gas outlet pipeline 5 is located. The cylinder is divided into two parts by the first mist catcher 71. When the gas on the side where the drainage pipeline 4 is located in the cylinder 1 passes through the first mist catcher 71, the droplets carried by the gas are captured by the first mist catcher 71 and retained on the side where the drainage pipeline 4 is located, which can further avoid the corrosion of the pipeline by the accumulated liquid. It can be understood that the first mist catcher 71 here refers to a sheet-shaped mist catcher commonly used in industry to remove moisture from gases such as natural gas.

[0050] The gas pipeline liquid accumulation collection device for the torch light provided in this embodiment can effectively prevent rainwater flowing down the light pipeline 100 from directly entering the gas pipeline 5, causing water accumulation in the gas pipeline 5, and effectively prevent the problems of torch flameout and pipeline corrosion caused by pipeline water accumulation. Since the gas outlet pipeline 5 and the light pipeline 100 are connected at a vertical relationship, the drainage pipeline 4 is also extended at the connection point between the gas outlet pipeline 5 and the light pipeline 100, the drainage pipeline 4 can guide the rainwater flowing down the light pipeline 100 into the cylinder 1, and prevent the accumulated water from entering the gas outlet pipeline 5 or the gas inlet pipeline 2. A drainage pipeline 3 is provided at the bottom of the cylinder 1, and the accumulated liquid in the cylinder 1 can be conveniently discharged through the drainage pipeline 3, so as to ensure that the air flow channel of the torch light pipeline 100 is unobstructed and the torch burns normally.

[0051] Example 2

[0052] like Figure 2 As shown, different from Example 1, in this embodiment, not only a first mist catching net 71 but also a second mist catching net 72 is provided in the cylinder 1. Specifically, the first mist catching net 71 is located between the drainage pipeline 4 and the air outlet pipeline 5. One end of the first mist catching net 71 is installed on the top of the cylinder 1, and the other end of the first mist catching net 71 is installed on the bottom of the cylinder 1. The second mist catching net 72 intersects with the first mist catching net 71. Furthermore, the second mist catching net 72 is perpendicular to the first mist catching net 71, and the first mist catching net 71 can be arranged at the axis of the cylinder 1. Figure 2 As shown, the second mist catching net 72 and the first mist catching net 71 divide the cylinder 1 into four parts: upper left, lower left, upper right, and lower right.

[0053] The cylinder is divided into four parts by the first mist catching net 71 and the second mist catching net 72. In this way, when the gas on the side where the drainage pipeline 4 is located in the cylinder 1 passes through the mist catching net, the droplets carried by the gas are captured by the mist catching net and retained on the side where the drainage pipeline 4 is located. When the gas at the bottom of the cylinder 1 flows upward, the second mist catching net 72 can further capture the droplets carried by the gas, which can further avoid the corrosion of the pipeline by the accumulated liquid. At the same time, the design of the double mist catching net can further improve the collection efficiency of water mist and fine droplets. It can be understood that the first mist catching net 71 and the second mist catching net 72 here refer to the sheet mist catching nets commonly used in industry to remove moisture from gases such as natural gas.

[0054] Example 3

[0055] like Figure 3 , 4As shown, different from Examples 1 and 2, in this embodiment, not only a first mist catching net 71 but also a second mist catching net 72 is provided in the cylinder 1. Specifically, the first mist catching net 71 is located between the drainage pipeline 4 and the air outlet pipeline 5. One end of the first mist catching net 71 is installed on the top of the cylinder 1, and the other end of the first mist catching net 71 extends toward the bottom of the cylinder 1, that is, the end of the first mist catching net 71 extending toward the bottom of the cylinder 1 does not contact the bottom of the cylinder 1, and the end of the first mist catching net 71 extending toward the bottom of the cylinder 1 extends out of the second mist catching net 72, and the second mist catching net 72 extends toward one side of the air inlet pipeline 2, that is, as shown in FIG. Figure 4 As shown, the first mist catching net 71 and the second mist catching net 72 are connected to form a structure similar to an "L" shape, and the edge 721 of the second mist catching net 72 is in contact with the side wall of the cylinder 1. Here, the contact means that the curvature of the edge 721 is the same as the side wall of the cylinder 1, so that the edge 721 and the side wall of the cylinder 1 fit each other. The first mist catching net 71 and the second mist catching net 72 divide the cylinder 1 into two parts. Specifically, the first mist catching net 71 is arranged on the axis of the cylinder 1, the second mist catching net 72 is a semicircular structure, and the first mist catching net 71 is perpendicular to the second mist catching net 72. It can be understood that the first mist catching net 71 and the second mist catching net 72 can be a split structure or an integrated structure.

[0056] With the structural setting of this embodiment, the first mist catching net 71 and the second mist catching net 72 are connected to form a structure similar to an "L" shape, and the second mist catching net 72 extends toward one side of the air inlet pipeline 2. The mist catching net of such a structure can divide the cylinder 1 into two irregular parts. The gas on the side where the drainage pipeline 4 is located in the cylinder 1 and the bottom of the cylinder 1 enters the side where the air inlet pipeline 2 and carries droplets, which are captured by the mist catching net and retained on the side of the drainage pipeline 4. This "L"-shaped structure reduces the amount of mist catching nets used and saves the production cost of the accumulated liquid collection device. It can be understood that the first mist catching net 71 and the second mist catching net 72 here refer to the sheet-shaped mist catching nets commonly used in industry to remove moisture from gases such as natural gas.
