Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a device for collecting and discharging acidic water from the reflux tank of a cracked gasoline hydrogenation stabilizer tower. Background Technology

[0002] The reflux tank of the stabilization tower in the cracked gasoline hydrogenation unit is an auxiliary device for the stabilization tower. Its main function is to collect the material condensed at the top of the stabilization tower. By separating the gas phase and the liquid phase, part of the liquid phase is returned to the stabilization tower as reflux liquid to maintain the stability of the operating temperature and pressure inside the tower, while the other part of the liquid phase is sent out as qualified product. The acidic water collection and discharge device is a device specifically used to collect, temporarily store and safely discharge wastewater containing acidic substances or acidic ions such as hydrogen sulfide and ammonia generated during the process. It can prevent the direct discharge of acidic water from causing equipment corrosion or environmental pollution. During the hydrocracking of gasoline, the material processed by the stabilizer tower contains trace amounts of impurities such as sulfides. These impurities dissolve into the aqueous phase during the condensation process at the top of the tower, forming acidic water. If acidic water accumulates in the reflux tank, it will not only corrode the reflux tank and subsequent pipelines, but also affect the quality of the reflux liquid and thus interfere with the normal operation of the stabilizer tower. Therefore, it is necessary to equip the reflux tank with an acidic water collection and discharge device to collect and discharge the acidic water in a timely manner, thereby ensuring equipment safety, maintaining stable operation of the unit, and avoiding environmental problems caused by acidic water, thus improving inherent safety from the source.

[0003] The acid water collection and discharge device for the reflux tank of the cracked gasoline hydrotreating stabilizer mainly consists of an acid water collection tank, liquid guiding pipelines and control valves, level detection instruments, pressure balancing pipelines, filter components, a transfer pump, and discharge pipelines. Some units are also equipped with heating facilities. During operation, the acid water collection tank or dedicated collection area serves as the core temporary storage space for acid water, used to centrally collect the acid water separated from the reflux tank. The liquid guiding pipelines are responsible for guiding the acid water from the reflux tank to the collection tank. The control valves can regulate the discharge rate of the acid water, preventing it from being discharged too quickly or too slowly, which could affect the stability of the unit. The level detection instruments can monitor the liquid level of the acid water in the collection tank in real time, preventing overflow due to excessively high levels or cavitation of the transfer pump due to excessively low levels. The pressure balancing pipelines can level the water. The pressure between the return tank and the collection tank ensures smooth flow of acidic water while maintaining stable pressure throughout the unit. The filter assembly performs preliminary filtration of the acidic water, removing small amounts of oily impurities to prevent blockage of subsequent pipelines or impact on wastewater treatment efficiency. The transfer pump, in conjunction with the discharge pipeline, transports the acidic water temporarily stored in the collection tank to the subsequent wastewater treatment unit, completing the transfer and treatment of the acidic water. The heating system primarily functions in low-temperature environments, preventing impurities in the acidic water from solidifying or freezing, thus avoiding pipeline blockage. Emergency discharge branches and safety pressure relief components serve as safeguards, allowing for timely discharge of acidic water or release of pressure in case of abnormal pressure or other emergencies, ensuring safe operation of the unit.

[0004] In existing technologies, the reflux tanks in some pyrolysis gasoline hydrostabilization tower reflux tank acid water collection and discharge devices discharge acid water at fixed intervals, rather than according to the actual amount of acid water. When the amount of acid water generated is large, fixed-time discharge will lead to excessive accumulation of acid water in the reflux tank or collection tank. Therefore, a pyrolysis gasoline hydrostabilization tower reflux tank acid water collection and discharge device is proposed to solve the above problems. Utility Model Content

The stabilizing tower 2 provides suitable space and reaction conditions for the hydrogenation stabilization reaction of cracked gasoline, allowing impurities such as unsaturated hydrocarbons in the cracked gasoline to complete the hydrogenation reaction inside the tower. A conveying pipe 3 is fixedly connected to the top of the stabilizing tower 2. The conveying pipe 3 can smoothly transport the mixed gas or liquid containing acidic water produced after the reaction in the stabilizing tower 2 to the cooling mechanism 8. The cooling mechanism 8 is fixedly connected to the left side of the conveying pipe 3. A reflux tank 4 is fixedly connected inside the fixed plate 1. The reflux tank 4 serves as a collection and temporary storage container for acidic water, receiving the acidic water separated after being cooled by the cooling mechanism 8.

[0022] It includes a stabilizing tower body 2, a conveying pipe 3, a return tank body 4, a discharge pipe 5, a drainage mechanism 6, and a dismantling mechanism 7; The top of the stabilizing tower 2 is fixedly connected to one end of the conveying pipe 3, and the other end of the conveying pipe 3 is connected to the cooling mechanism 8. A return tank 4 is connected below the cooling mechanism 8. A discharge pipe 5 is fixedly connected to the bottom inner wall of the return tank 4, and a drainage mechanism 6 is installed on the inner wall of the return tank 4.

The drainage mechanism 6 includes a baffle plate 62, a sealing plate 63, a moving rod 64, a T-block 65, a spring 66, a damping rod 67, and a limiting assembly 69. The discharge pipe 5 has a side slot, and two baffle plates 62 symmetrically enter the discharge pipe 5 through the side slot. A sealing plate 63 is fixedly connected to the adjacent side of each of the two baffle plates 62. The other side of each baffle plate 62 is fixedly connected to one end of the moving rod 64, and the other end of the moving rod 64 is fixedly connected to one vertical end of the T-block 65. The other vertical section of the T-block 65... A damping rod 67 is fixedly connected to the side, and a spring 66 is sleeved on the outside of the damping rod 67; the inner wall of the return tank 4 is provided with a groove for sliding connection of the limiting component 69; the limiting component 69 includes a moving plate 691, which is slidably connected to the groove in the inner wall of the return tank 4; a grooved plate 692 is fixedly connected to each adjacent side of the moving plate 691; a float 693 is fixedly connected to the grooved plate 692; the float 693 has a density less than water and generates buoyancy in water greater than the weight of the limiting component 69; The horizontal section of the T-block 65 is inclined near the inner wall of the return tank 4, and the bottom of the grooved plate 692 can slide in conjunction with the inclined surface. The spring 66 is in a compressed state in its natural state, pulling the T-block 65, the moving rod 64, the baffle plate 62, and the sealing plate 63 away from the discharge pipe 5. The mass and width of the grooved plate 692 are sufficient to overcome the tension of the spring 66 by sliding in conjunction with the inclined surface of the T-block 65, thus pushing the baffle plate 62 and the sealing plate 63 into the discharge pipe 5. The drainage mechanism 6 also includes a partition plate 61 with a central opening; the partition plate 61 is positioned between the float 693 and the T-block 65.

The connecting pipe 71 is connected to the main pipe 73 via an outer pipe 72. Two outer blocks 75 are fixedly connected to the outside of the side of the connecting pipe 71. A second moving rod 76 is slidably connected inside the outer block 75. A fixing ring 78 is connected to the periphery of the moving rod 76. A second spring 77 is fixedly connected to the outside of the fixing ring 78. The other end of the second spring 77 is connected to the inner wall of the outer block 75. A limiting rod 74 is fixedly connected to the inside of the moving rod 76. A limiting hole is provided at the corresponding position of the outer pipe 72 and the main pipe 73. After the limiting rod 74 cooperates with the limiting hole of the outer pipe 72, the outer pipe 72 and the main pipe 73 are fixedly locked. The cooling mechanism 8 includes a housing 81, the delivery pipe 3 passes through the outside of the housing 81 and connects to the cooling tank 83, an actuator 82 is fixedly connected to the outside of the housing 81, a cooling plate 84 is fixedly connected to the inside of the housing 81, and the cooling tank 83 is fixedly connected to the inside of the housing 81; the actuator 82 is a signal receiving device and is communicatively connected to the cooling plate 84, and the cooling plate 84 receives the signal from the actuator 82 to control the cooling process to start or stop.

[0023] As the acidic water rises, the float 693 floats upward, causing the grooved plate 692 to move. This causes the grooved plate 692 to move the moving plate 691, which in turn moves the moving plate 691 upward, freeing it from the force applied to the T-block 65. This allows the spring 66 and damping rod 67 to apply force, causing the T-block 65 to move and ultimately freeing the baffle plate 62 from the discharge pipe 5.

[0024] Reference Figure 2 and Figure 4 The disassembly mechanism 7 includes a connecting pipe 71, the inside of which is fixedly connected to the outside of the discharge pipe 5. The connecting pipe 71 serves as a bridge connecting the disassembly mechanism 7 and the discharge pipe 5. An outer pipe 72 is slidably connected inside the connecting pipe 71, connecting the connecting pipe 71 to the main pipe 73. The main pipe 73 is fixedly connected inside the outer pipe 72, and is connected to the discharge pipe 5, thus controlling the discharge of acidic water. Two outer blocks 75 are fixedly connected to the outside of the connecting pipe 71. The outer blocks 75 provide mounting and sliding support for the moving rod 76. By fixing themselves to the outside of the connecting pipe 71, they form... A stable mounting base has an outer block 75 with a sliding connection to a second movable rod 76. The second movable rod 76 connects a fixed ring 78 and a limiting rod 74, allowing it to move under the operator's control. The second movable rod 76 is fixedly connected to a fixed ring 78, which fixes a second spring 77 and transmits elastic force. The second movable rod 78 is fixedly connected to the outside of the second movable rod 76. The right side of the fixed ring 78 is fixedly connected to a second spring 77, which provides reset and locking force for the second movable rod 76 and the limiting rod 74. The left side of the second movable rod 76 is fixedly connected to a limiting rod 74, which locks or unlocks the connecting tube 71 and the outer tube 72. The second movable rod 76 moves, thereby driving the fixed ring 78 to move, causing the spring to compress. As the second movable rod 76 moves continuously, it causes the limiting rod 74 to disengage from the outer tube 72, thereby causing the main tube 73 to drive the outer tube 72 to move.

[0025] The implementation principle of this application embodiment is as follows: First, the operator introduces the liquid phase from the "hot high-temperature separation tank" of the C6-C8 two-stage hydrogenation and the liquid phase from the "cold high-temperature separation tank" of the C6-C8 two-stage hydrogenation into the stabilizing tower body 2 respectively. The gas generated then enters the cooling tank 83 under the action of the connecting tank. Under the action of the actuator 82, the gas in the cooling tank 83 is converted into liquid and enters the reflux tank 4, thereby causing the float ball 693 inside to move upward continuously. This causes the moving plate 691 to move upward, and the T-block 65 moves under the action of the damping rod 67 and the spring 66, causing the baffle plate 62 to move, thereby detaching from the discharge pipe 5 and discharging the acidic water, thus realizing the automatic discharge of the reflux tank.

[0026] Then, after prolonged use, if a problem occurs with the pipe, the operator pulls the second movable rod 76, causing it to move within the outer block. This causes the fixed ring 78 to press against the second spring 77. As the second movable rod 76 moves continuously, the limiting rod 74 is disengaged from the outer pipe 72, allowing the main pipe 73 to be replaced, thus achieving the disassembly and replacement of the pipe.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
