Description

Technical Field

[0001] This utility model relates to the field of oil collection tank technology, and in particular to an oil collection tank with a protective structure. Background Technology

[0002] The oil collection tank is mainly used to collect liquids and is usually located below the overflow weir of the tray. There are two main types: one is a collection tank with a downcomer, where the liquid phase automatically overflows to the next tray through the downcomer; the other is a fully withdrawable collection tank, where liquid phase reflux relies on an external supply. The function of the collection tank is to increase operational flexibility and help establish a circulating reflux as quickly as possible during startup.

[0003] The prior art disclosure number CN104623923A describes an anti-coking overvaporized oil collection tank. The collection tank is composed of one or more square trough-shaped components. One end of the collection tank near the tower wall on both sides overlaps the support ring, and the other end overlaps the edge of the collection channel, forming a state where the end overlapping the support ring is high and the end overlapping the edge of the collection channel is low, and it is inclined towards the collection channel.

[0004] This device can reduce the residence time of liquid in the oil collection tank, reduce flow resistance, prevent coking, and ensure the normal operation of the tower at high temperatures.

[0005] However, when processing high-resistivity oils (such as vacuum residue), the high-speed friction between the oil and the metal collecting tank / channel walls, along with turbulence, leads to severe static electricity buildup. The lack of static discharge measures causes the electrostatic potential to rise continuously, especially in hazardous environments such as the flash section of the vacuum tower where flammable and explosive oil-gas mixtures exist. Static discharge can trigger serious safety accidents. This technical deficiency severely restricts the safety and reliability of the unit under harsh operating conditions such as deep vacuum distillation.

[0006] Therefore, an oil collection tank with a protective structure is proposed. Utility Model Content

[0007] This utility model is an oil collection tank with a protective structure proposed to overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an oil collection tank with a protective structure, comprising an oil collection tank and multiple baffles installed on the top of the oil collection tank, wherein multiple conductive strips are fixedly connected to the bottom of the oil collection tank, and vertical strips are fixedly installed on the top of the multiple conductive strips, and the vertical strips extend through the bottom of the oil collection tank to the top and are fixedly connected to the adjacent baffles.

[0009] A current collector is fixedly connected to the bottom of multiple conductive strips. A socket is fixedly installed at the end of the current collector. A plug is inserted into one end of the socket. A wire is fixedly connected to one end of the plug. A terminal block is fixedly connected to the other end of the wire.

[0010] Furthermore, each of the conductive strips includes a long metal wire, which is fixedly installed at the bottom of the oil collection tank. The outer surface of the long metal wire is wrapped with a long insulating sleeve, which is also fixedly installed at the bottom of the oil collection tank. The long insulating sleeve effectively isolates the metal parts from direct contact with the oil, ensuring electrostatic conduction efficiency, preventing electrochemical corrosion, and extending the service life of the equipment.

[0011] Furthermore, each of the vertical bars includes a short metal wire, which is fixedly installed on the top of an adjacent long metal wire and passes through the oil collection tank. The short metal wire is fixedly connected to an adjacent baffle plate. A short insulating sleeve is fixedly fitted onto the outer surface of the short metal wire. The short insulating sleeve is fixedly connected to the oil collection tank, the adjacent long insulating sleeve, and the adjacent baffle plate. The short insulating sleeve effectively isolates the metal parts from direct contact with the oil, ensuring electrostatic conduction efficiency, preventing electrochemical corrosion, and extending the service life of the equipment.

[0012] Furthermore, the current collector includes a ceramic sleeve, which is fixedly connected to multiple long insulating sleeves. A current collector copper wire is fixedly connected inside the ceramic sleeve, and multiple joints of the current collector copper wire are provided through the ceramic sleeve and extend into the adjacent long insulating sleeve. The long metal wire is fixedly connected to two adjacent joints of the current collector copper wire. The ceramic sleeve has excellent high temperature resistance and insulation performance, and can work stably in high temperature oil environment, ensuring the long-term reliable operation of the current collector copper wire. At the same time, its high mechanical strength effectively protects the internal conductive circuit from external damage.

[0013] Furthermore, the ceramic sleeve and the bottom of the oil collection tank are fixedly connected by multiple connecting blocks, which enhances the structural stability between the ceramic sleeve and the oil collection tank.

[0014] Furthermore, the socket includes an insulating base, which is fixedly installed at the end of the ceramic sleeve. A metal base is fixedly connected to one inner wall of the insulating base, and the end of the current-collecting copper wire passes through the insulating base and is fixedly connected to the metal base. Elastic metal sheets are symmetrically fixedly connected to one side of the outer surface of the metal base. The elastic metal sheets ensure stable contact pressure and avoid poor contact caused by vibration.

[0015] Furthermore, the plug includes an insulating plug, which is fixedly connected to the rubber sleeve of the wire and inserted into the insulating base. One end of the insulating plug is fixedly connected to a metal block, which is located between two elastic metal pieces and abuts against the two elastic metal pieces. One end of the metal block is fixedly connected to a metal rod, which passes through the insulating plug and is fixedly connected to the copper wire inside the wire. The overall structure is simple and reliable, and facilitates quick plugging and unplugging operations.

[0016] The beneficial effects of this utility model are:

[0017] In use, this utility model presents an oil collection tank with a protective structure. By incorporating a static discharge structure at the bottom of the tank, consisting of conductive strips, vertical strips, and current collectors, it effectively solves the problem of static electricity accumulation caused by oil friction under high-temperature and high-flow-rate conditions in existing oil collection tanks. The conductive strips and baffles are electrically connected via the vertical strips, quickly discharging static charge to the grounding terminal via the current collectors, significantly reducing the risk of electrostatic discharge. This structure is specifically designed for high-resistivity media such as vacuum residue oil. Through multi-point discharge, it ensures that the static potential remains within a safe range, effectively preventing explosions caused by static sparks in dangerous areas such as the flash section of the vacuum tower. Simultaneously, the use of an insulating sleeve design ensures both conductive reliability and prevents electrochemical corrosion, significantly improving the safety and operational stability of the oil collection tank under harsh conditions such as deep vacuum distillation.

[0031] Working principle:

[0032] When the oil flows within the oil collection tank 1, static charge is generated through friction between the oil and the baffle plate 2 and the inner wall of the tank. This static charge is conducted through the following pathways:

[0033] The static charge accumulated on the baffle plate 2 is conducted through the short metal wire 11 that is fixedly connected to it;

[0042] The ceramic sleeve 5 is fixedly connected to the bottom of the oil collection tank 1 by the connecting block 9, which enhances the overall structural stability.
