A rapid oil unloading environmentally friendly cyclone device

Abstract

This utility model discloses a rapid oil unloading environmentally friendly swirling device. The key technical features include a bent pipe, one end of which is connected to a pipe inside the oil unloading port; and a swirling mechanism, which is fixedly connected to the other end of the bent pipe and connected to the oil unloading pipe. The swirling mechanism is used to guide the oil to flow in a spiral. The bent pipe design prevents the gravitational potential energy of the oil from being completely converted into downward potential energy, thus reducing the likelihood of oil overflow.

Description

Technical Field

[0001] This utility model relates to the field of petrochemicals, and more specifically, it relates to a rapid oil unloading environmentally friendly cyclone device. Background Technology

[0002] Ground-mounted unloading ports are commonly used devices for unloading oil at gas stations. The unloading port has a vertical pipe at the bottom. When unloading oil, the unloading pipe is inserted into the unloading port and connected to the pipe to unload the oil.

[0003] The GB 20952-2020 "Emission Standard of Air Pollutants for Gas Stations" stipulates that when using a hydrogen ionization detector to detect oil and gas leaks at closed points of the oil and gas recovery system, VOCs gas leakage at the ground-mounted unloading port of gas stations is a serious problem. According to the detection data from 2022 to 2023, the detection rate of the problem at the ground-mounted unloading port is as high as 95%.

[0004] The main reason for these problems is that the unloading pipeline is perpendicular to the ground at a 90° angle. During the unloading process, all the gravitational potential energy is converted into kinetic energy. The speed is too fast, which may cause some oil to spill due to the impact. At the same time, after unloading, the residual oil in the unloading pipe may drip into the internal space of the unloading port due to improper operation, causing the oil and gas to accumulate in the internal space of the unloading port and not dissipate, thus increasing the detection concentration of the ground-inserted unloading port. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fast oil unloading environmentally friendly cyclone device. The device uses a bend in the tube to prevent the gravitational potential energy of the oil from being completely converted into downward potential energy, thus making it less likely for oil to overflow.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid oil unloading environmentally friendly vortex mechanism, including a bent pipe, one end of which is connected to a pipe inside the oil unloading port;

[0007] And a swirl mechanism, which is fixedly connected to the other end of the bend and connected to the oil unloading pipe, is used to guide the oil spiral flow.

[0008] The present invention is further configured such that one end of the swirling mechanism connected to the unloading pipe extends out of the unloading port.

[0009] The present invention is further configured such that: the swirling mechanism includes a swirling tube, and the swirling tube is configured as a straight tube;

[0010] And a swirl plate, which is fixedly connected to the inner wall of the swirl tube and arranged in a spiral shape around the axis of the swirl tube.

[0011] The present invention is further configured such that: the swirling mechanism is provided with multiple swirling plates, which are evenly arranged around the axis of the swirling tube.

[0012] The present invention is further configured such that: one end of the vortex tube connected to the oil unloading tube is provided with an oil inlet quick connector.

[0013] The present invention is further configured such that: one end of the bent pipe connected to the inner pipe of the unloading port is provided with an oil outlet quick connector.

[0014] In summary, the present invention has the following advantages over the prior art:

[0015] 1. The present invention uses a bend in the pipe to prevent the gravitational potential energy of the oil from being completely converted into downward potential energy, thus making it less likely for oil to overflow.

[0016] 2. This utility model optimizes the rotation angle, thickness, and number of swirl plates, so that a negative pressure zone can be formed in the middle of the swirl tube, thereby accelerating the oil flow rate.

[0017] 3. This utility model changes the traditional straight pipe to a bent pipe, so that the disassembly port of the bent pipe can be moved to the outside of the oil discharge port, thus preventing the VOCs concentration in the oil discharge port from increasing due to oil dripping during disassembly.

[0018] 4. By setting up a swirling mechanism, this utility model concentrates the pressure generated by the maximum flow rate in the central control area during the overall oil unloading process, effectively improving the sealing performance of the sealing components. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] Example: A rapid oil unloading environmentally friendly cyclone device, see attached document. Figure 1 and attached Figure 2 It includes a bend 1 and a swirl mechanism 2. One end of the bend 1 is connected to a pipe inside the oil unloading port. The swirl mechanism 2 is fixedly connected to the other end of the bend 1 and is connected to the oil unloading pipe. The swirl mechanism 2 is used to guide the oil spiral flow.

[0025] By setting up bend 1, the gravitational potential energy of the oil will not be completely converted into downward potential energy, thus making it less likely for oil to overflow.

[0026] By setting up the swirling mechanism 2, the oil can flow smoothly downwards after its downward potential energy is reduced by driving the oil spiral flow.

[0027] Specifically, the end of the swirling mechanism 2 that is connected to the unloading pipe extends out of the unloading port.

[0028] By extending one end of the swirling mechanism 2 connected to the unloading pipe into the unloading port, it is less likely that oil will drip into the unloading port when the unloading pipe is removed from the swirling mechanism 2.

[0029] Specifically, the swirling mechanism 2 includes a swirling tube 21 and a swirling plate 22. The swirling tube 21 is configured as a straight tube. The swirling plate 22 is fixedly connected to the inner wall of the swirling tube 21 and is arranged in a spiral around the axis of the swirling tube 21.

[0030] The swirl plate 22 can guide the oil spiral to flow during the process of oil flowing through the swirl tube 21, thereby accelerating the downward flow of oil and ensuring that the oil can flow smoothly downward.

[0031] Specifically, the swirling mechanism 2 is provided with multiple swirling plates 22, which are evenly arranged around the axis of the swirling tube 21.

[0032] Specifically, the end of the swirling pipe 21 that connects to the unloading pipe is equipped with an oil inlet quick connector 3.

[0033] Specifically, a quick-connect oil outlet 4 is provided at the end of the bend 1 that connects to the pipeline inside the unloading port.

[0034] The quick-connect oil inlet connector 3 and quick-connect oil outlet connector 4 make it easier to connect and disconnect the vortex device during use.
