Description

Technical Field

[0001] The utility model relates to the technical field of oil loading, and more specifically to an oil loading system capable of realizing accurate metering of liquid and gaseous media. Background Art

[0002] Oil loading is an important operation process involving the transportation of oil or related oil products. It is the process of loading oil products (such as gasoline, diesel, kerosene, etc.) from storage facilities (such as oil tanks, oil depots) into transportation vehicles (such as oil tank trucks, railway tank cars).

[0003] When loading oil into a tank truck, accurate metering equipment is required to ensure that the quantity of oil loaded is consistent with the order or plan. However, there are two pipelines connected to the tank truck, a liquid pipeline and a gas pipeline. When the oil is input into the tank truck, gas will be mixed in the oil. Liquefied petroleum gas is loaded into the tank truck through the liquid pipeline, and the gas discharged from the tank truck returns to the storage tank through the gas pipeline. The entire loading process relies on the gas-liquid pipeline for pressure balance.

[0004] When loading existing oil products, the gas returned from the gas phase pipeline is not measured, and only the total amount of gas and liquid oil transported in the liquid phase pipeline is measured. However, during the loading process, the gas will be transported back to the oil tanker through the gas phase pipeline, which will cause the weight of the oil transported by the tanker to be less than the measured total amount of gas and liquid oil, resulting in the problem of weight deviation of the tanker truck.

[0005] In view of this, the utility model provides an oil loading system which can realize accurate metering of liquid and gaseous media. Summary of the invention

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings and provide an oil loading system which can measure the mass of the oil filled in the oil tanker and can realize accurate measurement of liquid and gaseous media.

[0007] Therefore, the utility model provides an oil loading system that can realize accurate metering of liquid and gaseous media, which includes an oil tank body, wherein an oil outlet is arranged at the bottom of the oil tank body, and an air inlet is arranged at the top of the oil tank body. The oil outlet transports the oil in the oil tank body to the oil tank truck, and the air inlet transports the gas mixed in the oil back to the interior of the oil tank body. A liquid phase delivery pipe is installed at the bottom of the oil outlet, and a gas phase delivery pipe is installed at the top of the air inlet. The outsides of the liquid phase delivery pipe and the gas phase delivery pipe are both provided with mounting components, and a liquid phase mass flowmeter and a gas phase mass flowmeter are respectively arranged on the tops of the two mounting components. The liquid phase mass flowmeter is used to measure the mass of the oil transported in the liquid phase delivery pipe, and the gas phase mass flowmeter is used to measure the gas transported in the gas phase delivery pipe.

[0008] As a further improvement of the present technical solution, the installation assembly includes an arc-shaped butt joint tube, a fixing cylinder is installed in the middle of the arc-shaped butt joint tube, a support frame is installed on the top of the fixing cylinder, a placement hole is opened on the top of the support frame, and a metering hole is opened on the outer surface of the arc-shaped butt joint tube.

[0009] As a further improvement of the technical solution, the arc-shaped butt joint pipe intercepts and butts the liquid phase delivery pipe, the liquid phase mass flowmeter is installed on the top of the support frame, and the measuring head at the bottom of the liquid phase mass flowmeter passes through the placement hole and is connected to the inside of the metering hole.

[0010] As a further improvement of the technical solution, the gas mass flowmeter is also installed on the gas phase delivery pipe through the installation component to measure the gas transported in the gas phase delivery pipe.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the oil loading system capable of realizing accurate metering of liquid and gaseous media, when filling the oil tanker with oil, one end of the liquid phase delivery pipe is connected to the oil outlet at the bottom of the oil tank body, and the other end is connected to the tank body of the oil tanker, and then one end of the gas phase delivery pipe is connected to the air inlet of the oil tank body, and the other end is connected to the tank body of the oil tanker. Two installation components are respectively installed with a liquid mass flowmeter and a gas mass flowmeter in the middle of the liquid phase delivery pipe and the gas phase delivery pipe, so that when the oil in the oil tank body is transported to the oil tanker through the liquid phase delivery pipe, the mass of the oil passing through the liquid mass flowmeter is measured, and the gas mixed in the oil is transported back to the oil tank body through the gas phase delivery pipe connected to the oil tanker. The gas phase mass flowmeter installed on the gas phase delivery pipe measures the gas transported back, and the mass measured by the liquid phase mass flowmeter is subtracted from the mass measured by the gas phase mass flowmeter to obtain the mass of the oil loaded in the oil tanker, thereby achieving the effect of accurately measuring the oil loaded in the oil tanker and avoiding the situation where the oil loading in the oil tanker is insufficient in mass.

[0013] 2. In the oil loading system that can achieve accurate metering of liquid and gaseous media, when the oil in the liquid delivery pipe passes through the arc-shaped butt joint, the arc-shaped pipe can ease the flow state of the oil, reduce the generation of turbulence and eddy currents, and make the oil flowing through the liquid mass flow meter more stable, thereby improving the accuracy of measurement, so that the liquid mass flow meter can better measure the decelerated oil. Similarly, the gas mass flow meter is installed through the arc-shaped butt joint to measure the flowing gas. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] During the existing oil product loading, the gas transported back in the gas-phase pipeline is not measured, and only the total amount of gas-liquid petroleum transported in the liquid-phase pipeline is measured. However, during the loading process, the gas will be transported back to the oil tank through the gas-phase pipeline, which will cause the weight of the oil transported by the oil tanker to be less than the total sum of the measured gas-liquid oil, resulting in problems with the deviation of the weight of the oil tanker from time to time.

[0021] As Figure 1 shown, the device includes an oil tank body 1. An oil outlet 2 is provided at the bottom of the oil tank body 1, and an air inlet 3 is provided at the top of the oil tank body 1. The oil outlet 2 transports the oil in the oil tank body 1 to the oil tanker, and the air inlet 3 transports the gas mixed in the oil back to the inside of the oil tank body 1. A liquid-phase conveying pipe 21 is installed at the bottom of the oil outlet 2, and a gas-phase conveying pipe 31 is installed at the top of the air inlet 3. Installation components 4 are provided on the outer parts of the liquid-phase conveying pipe 21 and the gas-phase conveying pipe 31. A liquid-phase mass flowmeter 22 and a gas-phase mass flowmeter 32 are respectively provided at the tops of the two installation components 4. The liquid-phase mass flowmeter 22 is used to measure the mass of the oil transported in the liquid-phase conveying pipe 21, and the gas-phase mass flowmeter 32 is used to measure the gas transported in the gas-phase conveying pipe 31.

[0022] When transporting oil to the tanker, a liquid mass flowmeter 22 and a gas mass flowmeter 32 are respectively installed in the middle of the liquid delivery pipe 21 and the gas delivery pipe 31 through two installation components 4, so that when the oil in the tank body 1 is transported to the tanker through the liquid delivery pipe 21, the mass of the oil is measured by the liquid mass flowmeter 22, and the gas mixed in the oil is transported back to the tank body 1 through the gas delivery pipe 31 connected to the tanker. The gas mass flowmeter 32 installed on the gas delivery pipe 31 measures the transported gas, and the mass measured by the liquid mass flowmeter 22 is subtracted from the mass measured by the gas mass flowmeter 32 to obtain the mass of the oil loaded in the tanker, thereby achieving the effect of accurately measuring the oil loaded in the tanker and avoiding the situation where the oil loaded in the tanker is insufficient in mass.

[0023] The liquid mass flowmeter 22 and the gas mass flowmeter 32 are metering devices in the liquid phase delivery pipe 21 and the gas phase delivery pipe 31, which are prior art, preferably, Corilio mass flowmeter, and its model is: LY-CMF50.

[0024] Considering the problem of how to install the liquid mass flow meter 22 and the gas mass flow meter 32, it is shown Figures 2 - 3 , the specific structure of the installation component 4 is disclosed, the installation component 4 includes an arc-shaped butt-joint pipe 401, a fixing cylinder 402 is installed in the middle of the arc-shaped butt-joint pipe 401, a support frame 403 is installed on the top of the fixing cylinder 402, a placement hole 404 is opened on the top of the support frame 403, and a metering hole 405 is opened on the outer surface of the arc-shaped butt-joint pipe 401. The arc-shaped butt-joint pipe 401 intercepts and butt-joints the liquid phase delivery pipe 21, the liquid phase mass flowmeter 22 is installed on the top of the support frame 403, and the measuring head at the bottom of the liquid phase mass flowmeter 22 passes through the placement hole 404 and is connected to the inside of the metering hole 405.

[0025] The gas mass flow meter 32 is also installed on the gas delivery pipe 31 through the installation component 4 to measure the gas delivered in the gas delivery pipe 31 .

[0026] By intercepting the liquid phase delivery pipe 21, the arc-shaped butt-joint pipe 401 is installed inside the liquid phase delivery pipe 21, and the fixed cylinder 402 is fixed in the middle of the arc-shaped butt-joint pipe 401, so that the liquid phase mass flowmeter 22 can be installed on the support frame 403 on the top of the fixed cylinder 402, and the placement hole 404 on the support frame 403 can limit and fix the measuring head at the bottom of the liquid phase mass flowmeter 22, thereby improving the measurement accuracy, so that when the oil in the liquid phase delivery pipe 21 passes through the arc-shaped butt-joint pipe 401, the arc-shaped curved pipe can ease the flow state of the oil, reduce the generation of turbulence and eddy currents, and make the oil flowing through the liquid phase mass flowmeter 22 more stable, thereby improving the measurement accuracy, so that the liquid phase mass flowmeter 22 can better measure the decelerated oil. Similarly, the gas phase mass flowmeter 32 is installed through the arc-shaped butt-joint pipe 401 to measure the flowing gas.

[0027] In summary, the working principle of this solution is as follows:

[0028] When filling the oil tanker, one end of the liquid phase delivery pipe 21 is connected to the oil outlet 2 at the bottom of the oil tank body 1, and the other end is connected to the tank body of the oil tanker. Then one end of the gas phase delivery pipe 31 is connected to the air inlet 3 of the oil tank body 1, and the other end is connected to the tank body of the oil tanker. Two mounting components 4 are respectively installed with a liquid phase mass flow meter 22 and a gas phase mass flow meter 32 in the middle of the liquid phase delivery pipe 21 and the gas phase delivery pipe 31, so that the oil in the oil tank body 1 is transported to the oil tank through the liquid phase delivery pipe 21. When the tanker is in operation, the mass of the oil is measured by the liquid mass flowmeter 22, and the gas mixed in the oil is transported back to the tank body 1 through the gas phase delivery pipe 31 connected to the tanker. The gas phase mass flowmeter 32 installed on the gas phase delivery pipe 31 measures the gas transported back, and the mass measured by the liquid mass flowmeter 22 is subtracted from the mass measured by the gas phase mass flowmeter 32 to obtain the mass of the oil loaded in the tanker, thereby achieving the effect of accurately measuring the oil loaded in the tanker and avoiding the situation where the oil in the tanker is insufficient in quality.
