Description

Technical Field

[0001] This utility model relates to oil tanker unloading, specifically an oil unloading platform filter. Background Technology

[0002] The process of unloading oil from a tanker truck is as follows: the tanker truck puts crude oil into the zero-position tank at the unloading platform. The crude oil in the zero-position tank is pressurized by the oil transfer pump and enters the three-phase separator. After the oil, gas and water are separated, the oil enters the next station from the three-phase separator.

[0003] Because the crude oil transported by tank trucks comes from a variety of sources, including oil produced from oil wells, crude oil recovered from cleaning pools and tanks, and crude oil recovered from the ground, the crude oil in the tank often contains impurities such as sand, cotton yarn, grass roots, and leaves. When these impurities enter the crude oil processing system, they can entangle the probe of the water content analyzer on the unloading platform, affecting the measurement accuracy, and can also clog the filters at the inlet of the oil pump and the inlet of the three-phase separator.

[0004] Due to space constraints, the filters at the inlet of the oil pump and the inlet of the three-phase separator are small in size. To ensure the flow rate, the filter screen pore size is 10mm. This results in many fine impurities entering the three-phase separator and clogging the flow meter impeller at the outlet, affecting the normal operation of the oil treatment system.

[0005] The reason for the above problems is that no filter was installed on the unloading platform. In fact, the unloading platform was originally equipped with a filter. However, the unloading platform only had a few unloading ports, and dozens of tank trucks lined up to unload oil every day. The filter affected the unloading speed, so it was removed.

[0006] Therefore, an oil unloading platform filter is needed that can ensure filtration effectiveness without affecting the oil unloading speed. Utility Model Content

[0007] The purpose of this invention is to provide an oil unloading platform filter that can increase the oil unloading speed while ensuring the filtration effect.

[0008] The technical solution adopted in this utility model is:

[0009] An oil unloading platform filter includes a housing; inside the housing, there is a partition that divides the interior of the housing into upper and lower layers, and the partition has through holes. A basket filter screen for filtering crude oil passing through the through holes is provided at the through holes. The basket filter screen has filter holes distributed and extends downward at the bottom; the housing is provided with an inlet, an outlet, an air balance pipe, and a heating component. The inlet and outlet are respectively connected to the upper and lower layers inside the housing. The inlet is used to connect to an external tank truck. The outlet is connected to a zero-position tank through an outlet pipe. The two ends of the air balance pipe are respectively connected to the top inside the housing and the top inside the zero-position tank. The heating component is used to heat the crude oil inside the housing.

[0010] Preferably, the basket filter screen has a flange at its upper end, and the basket filter screen passes through the through hole and is hung on the partition plate through the flange.

[0011] Preferably, the top of the housing is provided with a loading and unloading port, the size of which is sufficient for the basket filter screen to enter and exit, and the loading and unloading port on the housing is provided with an opening and closing component that can seal and open the loading and unloading port.

[0012] Preferably, the opening and closing assembly is a quick-opening blind plate, one side of which is hinged to the outer shell and the other side is connected to the outer shell via a movable hook. The quick-opening blind plate adopts a screw-tight sealing method and a side-opening opening method.

[0013] Preferably, the outlet pipe is provided with a moisture content meter probe hole for installing a moisture content meter.

[0014] Preferably, the probe of the moisture content meter is located at the bend of the outlet pipe and points towards the outlet.

[0015] Preferably, the heating component is a heating coil, and the working area of ​​the heating coil is located inside the housing and at the bottom of the housing.

[0016] Preferably, the end of the heating coil extends out of the outer casing.

[0017] Preferably, the outer shell is rectangular in shape, the through holes are circular, the basket filter is cylindrical with an open top, and the inlet and outlet have circular cross-sections.

[0018] Preferably, the outlet pipeline is a fixed pipeline.

[0019] The beneficial effects of this utility model are:

[0020] When unloading oil from a tanker truck, the outlet of the tanker truck is connected to the inlet of the outer shell via a hose. The crude oil in the tanker truck enters the upper layer of the outer shell through the inlet, then passes through a basket filter and enters the lower layer of the outer shell. It then flows out of the outer shell through the outlet and into the zero-level tank through the outlet pipe. In the above unloading process, the basket filter can ensure the filtration effect, the air balance pipe can reduce the impact of air resistance on the flow of crude oil, and the heating component can heat the crude oil to reduce viscosity and improve its fluidity. The high-inlet and low-outlet oil path can increase the drop to increase the crude oil flow rate and also reduce the amount of oil left in the outer shell after unloading. Therefore, this filter can increase the unloading speed while ensuring the filtration effect. Attached Figure Description

[0033] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0034] Example 1

[0035] This embodiment discloses an oil unloading platform filter, such as... Figures 1 to 3 As shown, it includes an outer shell 1, on which are provided a partition 2, a basket filter 3, an inlet 4, an outlet 5, an air balance pipe 6, and a heating assembly 7; wherein: the partition 2 is located inside the outer shell 1 and divides the interior of the outer shell 1 into upper and lower layers, and the partition 2 is provided with through holes, see Figure 2 The basket filter 3 is located at the through-hole. The basket filter 3 is used to filter crude oil passing through the through-hole. The basket filter 3 has filter holes distributed on it and extends downwards from the bottom. (See...) Figure 2 Inlet 4 and outlet 5 are respectively connected to the upper and lower layers inside the outer shell 1. The inlet is used to connect to external tank trucks, and the outlet is connected to the zero-position tank through outlet pipe 8. See Figures 1 to 3 The two ends of the gas balance pipe 6 are connected to the top inside the outer casing 1 and the top inside the zero-position tank, respectively, see Figures 1 to 3 Heating component 7 is used to heat the crude oil inside the outer casing 1, see Figure 1 and Figure 2 .

[0036] When unloading oil from the tanker truck: connect the outlet end of the tanker truck to the inlet 4 of the outer shell 1 through a hose. The crude oil in the tanker truck enters the upper layer of the outer shell 1 from the inlet 4 of the outer shell 1, then passes through the basket filter screen 3 and enters the lower layer of the outer shell 1. It then flows out of the outer shell 1 through the outlet 5 of the outer shell 1 and flows into the zero-level tank through the outlet pipe 8.

[0037] During the above oil unloading process, the basket filter 3 can ensure the filtration effect, the air balance pipe 6 can reduce the impact of air resistance on crude oil flow, the heating component 7 can heat the crude oil to reduce viscosity and improve crude oil fluidity, and the high inlet and low outlet oil path can increase the drop to increase the crude oil flow rate and also make the oil in the shell less after unloading. Therefore, the filter can increase the oil unloading speed while ensuring the filtration effect.

[0038] The flow area and pore size of the basket filter 3 are designed according to the required oil unloading speed and the composition of the impurities to be filtered.

[0039] like Figure 2 As shown, in this embodiment, preferably, the upper end of the basket filter screen 3 is provided with a flange, the basket filter screen 3 passes through the through hole and is hung on the partition plate 2 through the flange; the basket filter screen 3 is hung on the partition plate 2 by its own weight, and the buoyancy generated by the crude oil will also prevent the basket filter screen 3 from floating, so there is no need to set other fixing parts, and it is convenient to install and remove.

[0040] like Figures 1 to 3 As shown, in this embodiment, preferably: the top of the outer shell 1 is provided with a loading and unloading port, the size of which is sufficient for the basket filter screen 3 to enter and exit, and the loading and unloading port on the outer shell 1 is provided with an opening and closing component 9 that can seal and open the loading and unloading port; when the basket filter screen 3 needs to be cleaned or replaced after a period of use, first open the loading and unloading port with the opening and closing component 9, take out the basket filter screen 3, and then put the new or cleaned basket filter screen 3 into place, and then seal the loading and unloading port with the opening and closing component 9; when cleaning the basket filter screen 3, due to the presence of oil, for safety reasons, it needs to be processed in a different location and cannot be processed directly near the oil unloading platform. Furthermore: the opening and closing assembly 9 is a quick-opening blind flange. One side of the quick-opening blind flange is hinged to the outer shell 1, and the other side is connected to the outer shell 1 through a movable hook. The quick-opening blind flange adopts a screw-tightening sealing method and a side-opening opening method. When opening the loading and unloading port, first rotate to loosen the screw, then remove the hook and open the quick-opening blind flange side-opening. When sealing the loading and unloading port, first close the quick-opening blind flange, then hang the hook and tighten the screw.

[0041] like Figure 1 and Figure 3 As shown, in this embodiment, preferably, the outlet pipe 8 is provided with a water content analyzer probe hole 10 for installing a water content analyzer; after the water content analyzer is installed on the water content analyzer probe hole 10, the water content of the filtered crude oil can be directly measured. Furthermore, the water content analyzer probe hole 10 is located at the bend of the outlet pipe 8 and points towards the outlet, resulting in the best measurement effect.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, preferably: the heating component 7 is a heating coil, the working area of ​​which is located inside the outer casing 1 and at the bottom of the outer casing 1; since the bottom of the basket filter 3 extends downwards, the heating coil located at the bottom of the outer casing 1 can effectively heat the crude oil at the bottom of the basket filter 3, increasing its fluidity and preventing it from clogging at the bottom of the basket filter 3. Furthermore: the end of the heating coil is sealed and extends out of the outer casing to prevent crude oil leakage.

[0043] like Figures 1 to 3 As shown, in this embodiment, preferably: the outer shell 1 is rectangular in shape, the through holes are circular, the basket filter 3 is cylindrical with an open top, and the inlet 4 and outlet 5 have circular cross-sections; this structure of square outside and round inside facilitates the arrangement and installation of the outer shell 1.

[0044] Since the basic positions of the unloading platform filter and the zero-level tank remain unchanged, the outlet pipe 8 is preferably a fixed pipe.

[0045] Example 2

[0046] This embodiment discloses a second type of oil unloading platform filter, such as... Figure 4 As shown, the difference between this and Embodiment 1 is that the working area of ​​the heating coil is covered with a basket-type filter screen 3. This setup has a larger heating area than Embodiment 1, but it is more complex to manufacture and install.

[0047] Example 3

[0048] This embodiment discloses a third type of oil unloading platform filter, such as... Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the outlet pipe 8 does not have a moisture content meter probe hole 10 for installing a moisture content meter. This configuration eliminates the moisture content measurement function compared to Embodiment 1.
