Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste mineral oil treatment, in particular to a feed anti-scour device. Background Art
[0002] Waste mineral oil is a valuable resource. Its comprehensive utilization is crucial for alleviating my country's resource shortages, resolving the bottleneck of oil product supply and demand, improving the utilization rate of existing resources, and protecting the ecological environment. Waste mineral oil is listed on the National List of Hazardous Wastes, designated HW08. Waste mineral oil is a complex mixture of various substances, primarily C15-C36 alkanes, polycyclic aromatic hydrocarbons, alkenes, and phenols. Many of these components are toxic and harmful to the human body. If released into the environment in large quantities, they can cause serious environmental pollution, necessitating processing of waste mineral oil.
[0003] The processing equipment for waste mineral oil includes an oil extraction tower. However, when the oil extraction tower is used for a long time, the oil and gas flow rate is too fast, which causes the tower wall opposite the feed port to be eroded for a long time, causing the tower wall at that location to become thinner or perforated, posing a safety hazard.
[0004] For this reason, a feed anti-scour device is proposed. Utility Model Content
[0005] (1) Technical issues to be resolved
[0006] In order to overcome the shortcomings of the existing technology, a feed anti-scour device is proposed to solve the problem that during the long-term use of the oil extraction tower equipment in waste mineral oil, the tower wall opposite the feed port is subjected to long-term scouring due to the excessively fast oil and gas flow rate, which causes the tower wall at that location to easily become thinner or perforated, posing a safety hazard.
[0007] (2) Technical solution
[0008] The utility model is realized by the following technical solutions: The utility model proposes a feed anti-scour device, comprising
[0009] The anti-scour body is an integrally formed bullet-shaped body with an inlet at the top of its internal cavity.
[0010] The internal cavity of the anti-scour device body is connected to a cylindrical diversion conduit located at the center of the inlet, and one side of the internal cavity of the diversion conduit is through-set. The "bullet-shaped" bottom end of the anti-scour device body is provided with a penetrating fluid outlet connected to the opening of the diversion conduit, and a number of diversion flow holes are provided on the inside of the diversion conduit.
[0011] Furthermore, a connecting flange is provided at the top of the "bullet-shaped" anti-scour device body to connect with the external feed port.
[0012] Furthermore, the unopened end of the shunt conduit is connected with a solid pipe cap.
[0013] Furthermore, the front end of the tube cap can be set in an arc shape or a cone shape.
[0014] Furthermore, a circle of inwardly inclined bottom end force-bearing plates is provided at the connection between the inside of the anti-scour device body and the diversion conduit.
[0015] Furthermore, the diversion holes are arranged in an array inside the diversion conduit.
[0016] (3) Beneficial effects
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. In the present invention, the anti-scour device body is connected to the external feed port through a connecting flange, so that when the fluid enters the internal cavity of the anti-scour device body through the feed port, the fluid is forced to be diverted to the side when passing through the pipe cap, and the diverted fluid enters the diversion conduit through the side diversion flow hole. When inside the diversion conduit, the fluids impact each other, so that the impact forces offset each other and then enter the tower body, thereby achieving fluid blocking work, preventing the fluid from directly entering the tower body, and preventing the inner wall of the tower body from becoming thinner or perforated due to long-term scouring, so as to achieve the effect of increasing the service life of the equipment and extending the start-up cycle, making it safer and reducing cost consumption.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0026] See also Figures 1-4 The utility model provides a feed anti-scour device, including an integrally formed anti-scour device body 1, which increases the overall strength of the anti-scour device body 1, prevents it from being damaged by scouring, and increases its service life. The anti-scour device body 1 is in a "bullet-shaped" configuration, so that when the incoming fluid passes through the upper end when entering the interior of the anti-scour device body 1, a part of the impact is first generated, so that the impact force of the re-entry is reduced, reducing loss, and an inlet is provided at the top of its internal cavity, so that after the anti-scour device body 1 is connected to the feed port, the fluid can be input into the anti-scour device body 1 through the inlet for slowing down the flow, and the "bullet-shaped" top of the anti-scour device body 1 is provided with a connecting flange 2 for connection with the external feed port, so that it is easy to disassemble after connection, making installation more convenient. A cylindrical diversion conduit 4 is connected to the internal cavity of the anti-scour device body 1 and is located at the center of the inlet, so that after the fluid enters the interior of the anti-scour device body 1, it can directly contact the diversion conduit 4 for impact. The scourer body 1 is provided with a fluid outlet 3 at the bottom of the "bullet-shaped" end, which is connected to the opening of the scourer 4 to facilitate the discharge of the fluid from the inside of the scourer 4. The unopened end of the scourer 4 is connected to a solid pipe cap 5, so that the pipe cap 5 has better strength when impacted, reducing the damage caused by long-term impact, and the front end of the pipe cap 5 can be arc-shaped and cone-shaped, so that the fluid entering the interior can be diverted when impacted. A plurality of diversion holes 6 are provided on the inside of the scourer 4, and the diversion holes 6 are arranged in an array at the inside of the scourer 4 to facilitate the fluid after diversion by the pipe cap 5 to be input into the inside of the scourer 4 through the diversion holes 6 for counteraction, so that after the counteraction, the impacts offset each other, and the impact force of the fluid on the tower body becomes smaller, reducing damage to the tower body, and the array arrangement of the diversion holes 6 makes the counteraction more complete when the fluid enters the interior, avoiding the dispersion that causes poor impact.
[0027] Preferably, a circle of inwardly inclined bottom force-bearing plates 7 is provided at the connection between the interior of the anti-scourer body 1 and the diversion conduit 4, so as to prevent the fluid from contacting the bottom end of the anti-scourer body 1 during the process of entering the interior of the anti-scourer body 1 and moving inward, thereby causing a recoil force and poor impact effect. In this way, the fluid can be guided to flow inward when passing through the bottom force-bearing plate 7, reducing the recoil effect, and causing the fluid to enter the diversion conduit 4 to produce a counter-impact, thereby improving the anti-scour effect and reducing damage to the anti-scourer body 1.
[0028] Working principle: When in use, first connect the anti-scour device body 1 to the external feed port through the connecting flange 2, fix the anti-scour device body 1, and then the fluid enters the inlet at the front end of the anti-scour device body 1 through the feed port. After the fluid enters the interior of the anti-scour device body 1, the fluid contacts the internal pipe cap 5 and is diverted into two streams by the pipe cap 5. The two streams of fluid enter the diversion conduit 4 through the diversion flow hole 6 on the outside of the diversion conduit 4 and meet and collide with each other, so that the forces of the two fluids offset each other after the collision, and finally flow into the interior of the tower body through the fluid outlet 3, thereby completing the work.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
