Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Fig. 1 is a schematic view of a pipeline fluid separation storage, fig. 2 is a schematic view of a pipeline end cover of the pipeline fluid separation storage, fig. 3 is a schematic view of installation of a gas transmission pipeline and a storage pipeline, and referring to fig. 1-3, the pipeline fluid separation storage comprises a storage pipeline 2 and pipeline end covers 4 arranged at two ends of the storage pipeline 2, and the pipeline end covers 4 are detachably or fixedly connected with the storage pipeline 2. The pipeline end cover 4 is provided with a gas transmission pipe hole 401, and the gas transmission pipe hole 401 can be arranged at any position on the plane of the pipeline end cover 4. A gas transmission pipeline 10 penetrates through the gas transmission pipe hole 401 and is arranged in the gas transmission pipe hole 401 in a penetrating mode, a storage area 201 is formed between the outer wall of the gas transmission pipeline 10 and the inner wall of the storage pipeline 2, and the storage area 201 is used for storing impurities, wherein the impurities comprise water, oil, solid impurities and the like. The pipeline end cover 4 is connected with the gas transmission pipeline 10 in a sealing mode. The two pipeline end covers 4 divide the gas transmission pipeline 10 into a separation section 11 in the storage pipeline 2 and a connection section 12 outside the storage pipeline 2, and the connection section 12 is used for connecting a natural gas transmission pipeline. The pipe wall of the separation section 11 is provided with a plurality of holes at intervals, which are communicated with the storage area 201. When the pipeline fluid separation storage is installed, the storage area 201 is located below, and the gas transmission pipeline 10 is located above, so that impurities can enter the storage area 201 through the holes in the separation section 11.
The solid and liquid impurities are heavier than natural gas, and in the pipeline conveying process, the solid and liquid impurities in the natural gas flow at the lower wall of the pipeline, and the flow speed is low due to the friction resistance of the pipeline wall. During the process of passing through the separation section 11, solid and liquid impurities in the natural gas enter the storage area 201 through the holes on the separation section 11, while the natural gas with a high flow rate can enter the connection section 12 through the separation section 11; solid and liquid impurities in the natural gas flow at the lower wall of the pipeline under the action of gravity, because the natural gas in the pipeline has pressure, the friction resistance of the pipeline wall is larger when the large-specific gravity solid and liquid impurities flow along the lower wall of the pipeline under the action of pressure, the flow speed is slower, when the large-specific gravity solid and liquid impurities enter the separation section 11, the large-specific gravity solid and liquid impurities passively enter the storage area 201 from holes in the separation section 11 under the action of the pressure of the natural gas, and the pressure in the storage area 201 is balanced through the holes in the separation section 11. The natural gas is separated from the interference of solid and liquid impurities, and the flow speed is accelerated to flow forwards along the pipeline of the separation section 11. Natural gas and impurities are separated through the holes in the separation section 11, and the natural gas transportation pipeline is prevented from being blocked by the impurities.
Referring to fig. 1 to 3, after the gas transmission pipe 10 is inserted into the gas transmission pipe hole 401, the outer wall of the storage pipe 2 and the inner wall of the gas transmission pipe 10 are connected to form a contact portion 8. When the pipe fluid separation reservoir is installed, the contact portion 8 is located above and the storage area 201 is located below. The separation holes 111 and the pressure balance holes 112 are respectively arranged on the pipe walls at two ends of the separation section 11, and the larger the distance between the separation holes 111 and the pressure balance holes 112 is, the more the solid and liquid impurities can be prevented from flowing to the pressure balance holes 112, and the pressure balance holes 112 are prevented from being blocked.
As shown in fig. 1 to 3, the separation holes 11 are provided in the pipe wall of the separation section 11 on the side away from the contact portion 8. Since the storage pipe 2 and the gas transmission pipe 10 contact each other to form the contact portion 8, the storage area 201 can store the most foreign substances when the separation hole 111 is far from the contact portion 8. The separation holes 111 are plural and distributed along the axial direction of the gas transmission pipeline 10. The pressure balancing holes 112 are arranged on the tube wall at the bottom or at both sides of the separation section 11. The pressure balance holes 112 are plural and distributed along the axial direction of the gas transmission pipeline 10. The plurality of separation holes 111 and the plurality of pressure balance holes 112 are arranged to avoid blockage of the single separation hole 111 or the pressure balance hole 112, which leads to failure of the pipeline fluid separation storage. When the diameter of the storage pipeline 2 is 159mm, the diameter of the gas transmission pipeline 10 is 76mm, the separation holes 111 are arranged in three rows, 10 circular holes with 10mm in a row are formed, and the intervals of the holes are 20 mm; the pressure balance holes 112 are 2 10mm circular holes arranged at intervals.
Referring to fig. 1-3, when the impurities carried in the natural gas are less, the storage area 201 has a volume sufficient for storing the impurities, and when the impurities carried in the natural gas are more, a drain pipe 3 may be disposed on a side of the storage pipe 2 away from the contact portion 8 to communicate with the storage area 201, and a drain valve 5 is disposed on the drain pipe 3. The two ends of the gas transmission pipeline 10 are provided with connecting flanges 7 so as to connect the gas transmission pipeline 10 and a natural gas transportation pipeline. And a pressure gauge 6 is arranged on one connecting section 12 close to the separation hole 111, and the pressure in the pressure gas transmission pipeline 10 is detected through the pressure gauge 6.
When the pipeline fluid separation storage is installed, one of the connecting sections 12 close to the separation hole 111 is connected with the inlet section of the natural gas transportation pipeline, the other connecting section 12 is connected with the outlet section of the natural gas transportation pipeline, the contact part 8 is positioned right above, and the sewage discharge pipeline 3 is positioned right below. When natural gas and impurities pass through the separation hole 111 on the separation section 11, the impurities enter the storage area 201 through the separation hole 111 under the action of gravity and air pressure, the natural gas enters the natural gas transportation pipeline outlet section through the separation section 11, when the impurities pass through the separation hole 111, the pressure balance hole 112 balances the air pressure in the storage area 201, and when the impurities in the storage area 201 are accumulated to a certain height, the blow-off valve 5 is opened to discharge the impurities out of the storage area 201 through the blow-off pipeline 3.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
