Description

Technical Field

[0001] The invention belongs to the field of oil pipelines, and in particular relates to an auxiliary matching system for bulk oil batch transportation. Background Art

[0002] The main way to ensure oil supply during wartime is through oil pipelines. Generally, oil pipelines are made of several grooved steel pipes or standard hoses connected by joints. The operating environment of oil pipelines is generally harsh. Frequent large-scale connection and disassembly and replacement of pipelines at the transportation site cause the following two problems: On the one hand, it causes certain harm to the oil pipeline. For example, impurities in the oil pipeline, such as particulate matter, moisture, oxygen and carbon dioxide, can cause pipeline blockage, corrosion and scaling, reduce oil transportation efficiency, and even cause safety accidents; on the other hand, it reduces the quality of the oil, which in turn causes a series of problems such as reduced performance of the power mechanism of the subsequent operating equipment, increased fuel consumption, and increased failures.

[0003] Therefore, it is necessary to design an integrated bulk oil batch transportation auxiliary supporting system, which should be placed between the end of the entire oil pipeline system and the rear oil depot to quickly build an oil transportation channel. The system integrates multiple functions such as oil filtration and metering, pipeline pre-recovery pipe cleaning filtration, and pipe cleaning device reception to improve the efficiency of the oil pipeline system in the process of mission preparation, deployment, implementation support, and equipment withdrawal, and comprehensively enhance the support capability of the bulk oil batch transportation system.

[0004] In order to integrate multiple functions, large and complex pipeline connections are designed. On the one hand, it increases the weight of the entire system, and on the other hand, it increases the volume of the entire system. The work efficiency during use is low, which is not conducive to the rapid construction of oil pipelines. Therefore, it is not suitable for the construction of emergency oil pipelines. In actual use, when faced with an operating environment with limited accommodating space, the volume of the system integrating multiple functions is too large. Once it is larger than the accommodating space, the system cannot be transported or used normally. How to realize the multiple functions of the system while taking into account the miniaturization and lightweight of the system is an urgent problem to be solved. Summary of the invention

The branch pipeline of the pig receiving device 200 can be detachably connected to the inlet of the inlet pipeline 111. One end of the main pipeline of the pig receiving device 200 is an inlet connected to the upstream oil pipeline, and the other end of the main pipeline of the pig receiving device 200 is an outlet, and a plugging cover is provided at the outlet. The pipe cleaner assembly 110 has the functions of decompression and pipe cleaner receiving, and improves the guarantee capability of the bulk oil batch delivery system. The valve is referred to as valve. The front side wall, rear side wall, left side wall and right side wall of the container 100 are all provided with access doors, the filter separator 131 in the filter metering device is arranged at the corresponding access door at the left end of the container, and the flow stabilizer in the gas-liquid separation device is arranged at the access door at the right end of the container; the door frame corresponding to the access door of the container and the opening part of the container, and the door frame and the access door are sealed with sealing strips.

[0022] The inlet pipeline 111 , the filter metering device 130 , and the gas-liquid separation device 120 are all equipped with a pressure gauge 102 , and the filter metering device 130 , the gas-liquid separation device 120 are connected to the oil collecting basin 101 .

[0023] The filtering and metering device 130 includes a filter separator 131, a coarse filter 132, and a flow meter 133. The coarse filter 132 includes two coarse filters arranged in parallel, one coarse filter is installed on pipeline one, and the other coarse filter is installed on pipeline two.

The outlet of the outlet pipeline 114 can be detachably connected to the outlet joint, and the outlet joint is an outlet elbow 201.

[0024] When the upstream oil pipeline completes the oil transportation operation and is in the gas cap emptying stage, the cleaning sending device at the front end of the upstream oil pipeline is loaded with a cleaning pig, and the compressed gas is provided by the pressure test emptying cabin in front. The compressed air is used to force the cleaning pig from the cleaning sending device into the upstream oil pipeline. The cleaning pig cleans along the upstream oil pipeline. After the cleaning pig reaches the cleaning receiving device 200, the compressed air is stopped, the gas source is turned off, the internal pressure of the cleaning sending device is removed, and the residual oil or foreign matter and residual oil in the upstream oil pipeline are swept into the oil tank or oil tank downstream of the oil pipeline from the container inlet, the cleaning pig assembly 110, the gas-liquid separation device 120, and the filtering and metering device 130.

[0025] After the pig receiving device 200 of the pig assembly 110 receives the pig ball 8, the plug-in and rotating plug cover assembly 103 is opened by the plug-in and rotating wrench to remove the pig ball 8. After the pig ball 8 is removed, the plug-in and rotating plug cover assembly 103 is plugged, and the oil transportation operation can be carried out.

The inlet of the inlet pipeline 111 is connected to the oil transportation pipeline, and the outlet of the outlet pipeline 114 is connected to the oil tank or oil tank downstream of the oil transportation pipeline.

[0027] During the oil transportation operation, the valves at the inlet and outlet of the gas-liquid separation device 120 are in an open state, the valves at the inlet and outlet of the filter separator 131 are in an open state, and the oil flows in the following direction: the inlet of the inlet pipeline 111 → the inlet pipeline 111 → the gas-liquid separation pipeline 120 → the filter metering pipeline 130 → the outlet of the outlet pipeline 114 → the rear oil depot.

[0028] When the oil quality is high, close the inlet and outlet valves of the gas-liquid separation device 120, close the inlet valves of the filter separator 131 and the outlet valves of the filter separator 131, and open the butterfly valves on the connecting branches 113 and 134, so that the oil does not pass through the gas-liquid separation device 120 and the filter separator 131 but flows directly from pipeline 1, branch 134, and pipeline 3 to the outlet of the outlet pipeline 114, thereby improving the infusion efficiency of the entire system.

[0029] When the oil quality is very high, close the inlet and outlet valves of the gas-liquid separation device 120, close the butterfly valves installed at both ends of the coarse filter, the inlet valve of the filter separator 131 and the outlet valve of the filter separator 131, open the valves on the connecting branch 113 and the outlet pipeline 114, and the oil passes through the gas-liquid separation device 120 and the filter metering device 130 and flows out directly from the outlet of the outlet pipeline 114, further improving the infusion efficiency of the entire system.

[0030] The inlet of the inlet pipeline 111 is the container inlet, and the outlet of the outlet pipeline 114 is the container outlet.

[0031] The process flow of the present invention is an integrated system. A plurality of pressure gauges are installed on the pipeline of the integrated system. The functions that can be realized are: normal oil transportation during pipeline transportation, online sampling, filtration metering, replacement of filter separator filter element without interrupting oil transportation, replacement of coarse filter element without interrupting oil transportation; during the pipeline cleaning process after the pipeline transportation is completed, the pipeline cleaning terminal receives the pipe cleaner, and gas and oil are separated during pipeline cleaning; the tank in the gas-liquid separator is emptied before withdrawal, and sewage is discharged from the gas-liquid separator. It also has an alarm prompt function when the pressure behind the pressure reducing valve exceeds 1.0 MPa, the pressure difference between the inlet and outlet of the filter separator exceeds 0.15 MPa, and the pressure difference before and after the coarse filter exceeds the specified value. The detailed description is as follows: (1) Normal oil delivery, filtration, metering and online sampling The gas-liquid separation device 120 is connected in parallel between the pig assembly 110 and the filter metering device 130. During the normal transportation process of the system pipeline, the oil product contains a small amount of impurities and water droplets through the pig assembly 110 inlet → sampler 112 → pressure reduction to 1.0 MPa, through the filter metering device 130 valve two 2 → coarse filtration → valve seven 7 → valve three 3 → filter separator → valve five 5 → valve six 6 → flow meter → valve seven 7 → container outlet, filtered and separated and purified oil is metered to the downstream of the pipeline.

[0032] The inlet pressure of the pressure reducing valve 115 in the pipe cleaning assembly 110 is ≤6.0 MPa, and the outlet pressure is ≤1.0 MPa; when the oil flows through the sampler 112, the oil sample can be taken online for analysis and observation of the oil direction; the impurities in the oil are coarsely filtered, and the particles in the oil after filtration are ≤200 microns; the coalescing separation filter element in the filter separator 131 can further filter fine impurities, and the separation filter element coalesces tiny water molecules into larger water particles and separates them out. The gas generated during oil transportation is discharged through the gas-liquid separation device; the flow meter 133 can measure the volume of oil flowing through.

[0033] (2) During the oil pipeline oil transportation process, the filter metering device 130 also has the following functions: (a) Online filter blockage elimination function During the continuous oil transportation process of the pipeline, if the coarse filter is found to be blocked, open the valves before and after another coarse filter online and close the two valves before and after the blocked coarse filter.

[0034] (b) Without filter separator When the oil is relatively clean, it can be output without passing through the filter separator 131 .

[0035] (3) Pipeline cleaning (d) Gas and oil separation during pipeline cleaning Process 1: pig receiving device 200 → valve A → flow restrictor 1200 → primary cyclone 1201 → flow stabilizer 1202 → valve C → secondary cyclone 1203 → coalescer 1204 → flame arrester 1205, discharged to the atmosphere.

[0037] (e) During pipeline cleaning, the terminal can receive the pig Process: The pig cleans the oil pipeline under pressure → the pig receiving device 200 at the container inlet. At this time, the pointer of the pig receiver is biased to one side. When the pipeline stops cleaning, open the air release valve on the pig receiver. After the pressure is released, open the end cover of the pig receiver and take out the pig.

[0038] Oil at the front end of the pig → container inlet → pig assembly 110 → gas-liquid separation device.

[0039] (4) Before pipeline withdrawal (f) Empty the tank in the gas-liquid separator before the pipeline is withdrawn Compressed air → valve A → valve B → valve I → filter metering device.

[0041] Figure 2 , 3 In the process, the filter metering device 130 adopts three operation modes: over-station, coarse filtration + metering, coarse filtration + filtration separation + metering, which meet the needs of the terminal process of the oil pipeline system. The double coarse filtration is adopted in parallel and can be replaced online. The functions of the filter metering device 130 are: normal oil transportation at the terminal, replacement of filter separator filter element without interruption of oil transportation during normal oil transportation, replacement of coarse filter element without interruption of oil transportation, and over-station.

[0045] (c) Replace the coarse filter element without interrupting the oil flow during normal oil flow Valve nine 9→coarse filter→valve ten 10→valve four 4→filter separator→valve five 5→valve six 6→flow meter→valve seven 7→container outlet.

[0046] (d) Overstepping the station Valve one 1→valve eight 8→container export.

[0047] The above functions can be realized by manually switching the valve in the pipeline of the filter metering device.
