Description

Technical Field

[0002] Gasoline hydrogenation units usually produce acidic water, i.e., sulfur-containing wastewater, during production. If this part of sulfur-containing wastewater is directly discharged into the factory's sewage treatment unit, it will not only increase the treatment load of the sewage treatment unit, but also fail to recycle the beneficial water in the acidic water.

[0003] The existing recycling system has the following shortcomings:

[0004] 1. It is impossible to switch the spacing of the tower plates according to the degree of contamination of the acidic water, which easily causes the problem of mist entrainment, resulting in the inability of high-temperature steam and acidic water to fully merge, reducing the removal efficiency of toxic gases in the acidic water, thereby reducing the effect of recovery and treatment.

[0005] 2. The activated carbon adsorption unit is generally fixed in position.

[0024] Beneficial effects of the present invention:

[0025] 1. The present invention designs a fusion mechanism, namely, a first evacuation plate, a second evacuation plate and an adjustment component, and designs an ORP sensor. When it is detected that the pollution degree of the acidic water entering the liquid inlet pipe becomes larger, the adjustment component is started by the controller, so that the second evacuation plate slides down and the distance with the first evacuation plate is increased to prevent the entrainment of mist and foam, which is beneficial to improve the fusion of high-temperature steam and acidic water and improve the separation effect of toxic gases in acidic water.

[0026] 2. The present invention can make the fusion mechanism and the air intake mechanism operate in conjunction by designing a traction component, that is, while the distance between the first evacuation plate and the second evacuation plate is increased, the delivery amount of high-temperature steam into the tank body is simultaneously increased, thereby ensuring that sufficient high-temperature steam can be fused with the acidic water with greater pollution, reducing the partial pressure in the gas phase, and then promoting the volatile components in the acidic water to enter the gas phase more easily, thereby achieving an effective steam stripping effect.

[0027] 3. The present invention can realize the linkage operation of the air intake mechanism and the filtering mechanism by designing the transmission component, that is, while increasing the delivery amount of high-temperature steam into the tank body, it can simultaneously drive the filter frame to shake horizontally, so that the activated carbon in the filter frame can shake horizontally. On the one hand, the acidic water adhering to the surface of the activated carbon can be thrown off, thereby improving the recovery efficiency of the acidic water and avoiding waste of resources. On the other hand, it can prevent the acidic water with heavy pollution from retaining more impurities on its surface after being filtered by the activated carbon, thereby slowing down the subsequent flow rate of the acidic water, thereby ensuring the stable operation of the recovery and treatment work.

[0028] 4. The present invention degasses, deoils, removes toxic gases and organic matter, heavy metal ions, suspended impurities and pigments from acidic wastewater in sequence by designing a degassing tank, a deoiler, a recovery tank, a liquid inlet mechanism, a fusion mechanism, an air inlet mechanism and a filtering mechanism. Specifically:

[0029] Degassing is used to remove low-carbon hydrocarbons in acidic water to prevent equipment damage or even explosion when processing acidic water in the recovery tank, thereby improving the safety of recovery. The degassed acidic water is input into the deoiler for oil removal to prevent the subsequent acidic water from destroying the gas-liquid balance in the recovery tank due to oil content, resulting in operational disorder and affecting the treatment efficiency. The deoiled acidic water enters the recovery tank, and the separated waste gas is discharged from the exhaust pipe to ensure the recovery of beneficial water in the acidic water. The beneficial water is finally discharged from the drain pipe. By multi-stage treatment of the acidic water, the full recovery and utilization of the beneficial components therein is achieved, greatly improving the practicality of this system.

[0030] 5. The present invention realizes the sequential linkage of the fusion mechanism, the air intake mechanism and the air intake mechanism through the traction assembly and the transmission assembly, that is, the synchronous operation of the three mechanisms can be realized only through the single driving source of the electric push rod, which greatly reduces the power consumption of the recovery system and saves the cost of recycling acidic water. At the same time, it greatly reduces the overall structure of the system and reduces the construction cost of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Reference Figures 1 to 11 As shown, a gasoline hydrogenation acidic water recovery and utilization system includes a recovery tank, wherein the recovery tank includes a top cover 11 and a tank body 12, and the top cover 11 is fixed to the top of the tank body 12 by a plurality of bolts;

[0049] The fusion mechanism is arranged on the recovery tank, and the fusion mechanism includes a first evacuation plate 16, a second evacuation plate 17 and an adjustment assembly 18. The first evacuation plate 16 is fixedly arranged on the inner top of the tank body 12, and the second evacuation plate 17 is slidably arranged below the second evacuation plate 17 through four slide bars 19. The adjustment assembly 18 is inserted on the outer wall of the top cover 11, and the second evacuation plate 17 is fixedly connected to the adjustment assembly 18;

[0050] The air intake mechanism is arranged on the outer wall of the tank body 12, and the air intake mechanism includes a cover 20, an air intake pipe 21, a traction assembly 22, a conveying assembly 23, a lifting assembly 24 and a plurality of air outlet heads 25. The air intake pipe 21 is inserted into the tank body 12, the cover 20 and the conveying assembly 23 are respectively fixed at both ends of the air intake pipe 21, the lifting assembly 24 is inserted into the cover 20, and a plurality of air outlet heads 25 are arranged at equal intervals on the conveying assembly 23, and the traction assembly 22 is arranged between the second evacuation plate 17 and the lifting assembly 24;

[0051] The filtering mechanism is arranged on the tank body 12, and the filtering mechanism includes activated carbon 26, a filter frame 27, a pressing assembly 28 and a transmission assembly 29. The filter frame 27 is slidably arranged on the inner bottom of the tank body 12 through two sliding rods 30. The activated carbon 26 is arranged inside the filter frame 27. The pressing assembly 28 is arranged between the transmission assembly 29 and one of the sliding rods 30. The transmission assembly 29 is arranged between the traction assembly 22 and the pressing assembly 28. The adjustment assembly 18 is electrically connected to the controller.

[0052] Reference Figures 1 to 11 As shown, the rotating assembly 15 includes a support shell 31, a discharge pipe 32, a docking pipe 33 and four liquid outlet pipes 34. A discharge port is provided at the bottom of the conical guide pipe 14. The discharge pipe 32 is fixedly arranged at the bottom end of the discharge port. The support shell 31 is fixedly arranged at the bottom of the conical guide pipe 14. The docking pipe 33 is rotatably arranged on the support shell 31 through a bearing 35. The diameter of the discharge pipe 32 is smaller than the diameter of the docking pipe 33. The four liquid outlet pipes 34 are arranged at equal intervals, and the docking pipe 33 is connected to the four liquid outlet pipes 34. When acid water is recovered, the acid water is first degassed through a degassing tank (not shown in the figure) to remove low-carbon hydrocarbons in the acid water, to prevent the recovery tank from treating the acid water and causing equipment damage or even explosion, to improve the safety of recovery, and the degassed acid water is input into a deoiler (not shown in the figure) for deoiling to avoid the subsequent acid water containing oil from destroying the gas-liquid balance in the recovery tank, resulting in The operation is disordered and affects the processing efficiency. The end of the liquid inlet pipe 13 away from the top cover 11 is connected to the output end of the deoiler, so that the acidic water after deoiling enters the interior of the conical guide pipe 14 through the liquid inlet pipe 13 and the liquid inlet. Since the discharge pipe 32 is fixedly connected to the discharge port at the bottom of the conical guide shell 65, the butt joint 33 is rotatably connected to the support shell 31 through the bearing 35, and the support shell 31 is fixedly connected to the conical guide shell 65. The discharge pipe 32 is inserted into the interior of the butt joint 33, and the diameter of the discharge pipe 32 is smaller than the diameter of the butt joint 33. The four liquid outlet pipes 34 are designed with equal intervals, and the butt joint 33 is connected to the four liquid outlet pipes 34. As a result, the acidic water falling from the butt joint 33 to the four liquid outlet pipes 34 will use the inertia of the acidic water flowing out to drive the four liquid outlet pipes 34 to rotate while entering the top of the first evacuation plate 16, thereby realizing the uniform transportation of the acidic water to the first evacuation plate 16.

[0053] Reference Figures 1 to 11 As shown, the tops of the first evacuation plate 16 and the second evacuation plate 17 are both provided with water receiving grooves, and the ends of the first evacuation plate 16 and the second evacuation plate 17 away from the water receiving grooves are respectively provided with conical water receiving holes 36 and cylindrical air vents 37, each of which is connected with a cylindrical air vent 37. When the acidic water is uniformly transported to the water receiving groove at the top of the first evacuation plate 16 by the four rotating liquid outlet pipes 34, the plurality of conical water receiving holes 36 on the first evacuation plate 16 disperse the batch of acidic water in the water receiving groove into a plurality of thin streams, which are transported to the top of the second evacuation plate 17 through the cylindrical air vents 37. At the same time, the high-temperature steam entering from the input pipe 53 enters the conveying channel 52 through the gap between the circulation ring 50 and the conical sealing plug 49, enters the air inlet pipe 21, and then passes through the air inlet pipe 21, the air delivery pipe 54, the dispersion pipe 55, the plurality of branch pipes 56 and A plurality of gas outlets 25 are transported from bottom to top inside the tank body 12 until they pass through a plurality of cylindrical vent holes 37 at the bottom of the second evacuation plate 17, and are discharged through a plurality of conical water receiving holes 36 on the second evacuation plate 17 to contact with the acidic water dripping from the first evacuation plate 16, so as to diffuse the volatile toxic gases in the acidic water into the steam in contact with it, such as toxic gases such as ammonia, hydrogen sulfide and carbon dioxide. It should be noted that the conical water receiving holes 36 and the cylindrical vent holes 37 on the second evacuation plate 17 are designed to be larger than the conical water receiving holes 36 and the cylindrical vent holes 37 on the first evacuation plate 16, so as to facilitate the acidic water to drip in a thin stream, while the high-temperature steam rises in a large stream, so as to achieve the wrapping of the thin stream of acidic water by the high-temperature steam, thereby improving the contact effect of the steam on the acidic water, and quickly extracting the toxic gases in the acidic water, which is beneficial to improving the treatment efficiency.

[0054] Reference Figures 1 to 11As shown, the regulating assembly 18 includes an electric push rod 38, a push block 39 and a push rod 40.

The top cover 11 and the first evacuation plate 16 are both slidably connected to the push rod 40. An ORP sensor 41 is inserted on the outer wall of the liquid inlet pipe 13. The electric push rod 38 and the ORP sensor 41 are both electrically connected to the controller. When the ORP sensor 41 detects that the pollution degree of the acidic water entering the liquid inlet pipe 13 is relatively large, the amount of high-temperature steam to be delivered increases, thereby ensuring that there is sufficient high-temperature steam to be able to separate the acidic water with relatively large pollution. At this time, it is necessary to adjust the distance between the first evacuation plate 16 and the second evacuation plate 17 to reduce the entrainment of mist and foam and avoid affecting the separation effect. Therefore, when the acidic water pollution degree is detected to be large, the electric push rod 38 is started by the controller, so that its output end extends to the end close to the top cover 11. Since its output end is fixedly connected to the push block 39, the push block 39 is fixedly connected to the second evacuation plate 17 through the push rod 40, the top cover 11 and the first evacuation plate 16 are both slidably connected to the push rod 40, and the second evacuation plate 17 is slidably connected to the inside of the tank body 12, and then the second evacuation plate 17 is driven to drop to a certain height through the push rod 40 to prevent the entrainment of mist and foam, which is beneficial to improve the fusion of high-temperature steam and acidic water and improve the separation effect of toxic gases.

[0055] Reference Figures 1 to 11As shown, the traction assembly 22 includes a pull rod 42, a lifting plate 43, a connecting rod 44, two swing rods 45 and two first plug rods 46.

Each swing rod 45 is designed with a first slot and a second slot at both ends of the rotating shaft 47, and each first plug rod 46 is plugged into a first slot. Therefore, when the second evacuation plate 17 slides down, the downward pressure applied by the two first plug rods 46 in the two first slots forces the two swing rods 45 to rotate counterclockwise with the rotating shaft 47 as the center.

[0056] Reference Figures 1 to 11 As shown, the lifting assembly 24 includes a lifting rod 48, a conical sealing plug 49, a circulation ring 50 and two second plug rods 51.

The two second plug rods 51 are fixedly connected to the top of the lifting rod 48, and each second plug rod 51 is plugged into a second slot. Then, when the two rocker arms 45 rotate counterclockwise with the rotating shaft 47 as the center, the conical sealing plug 49 is driven by the lifting rod 48 to rise to the top of the circulation ring 50, so that the circulation ring 50 is no longer blocked, thereby increasing the high-temperature steam delivery rate passing through the circulation ring 50, and then increasing the high-temperature steam delivery rate entering the tank body 12, which can reduce the partial pressure in the gas phase, thereby promoting the volatile components in the acidic water to enter the gas phase more easily, and achieving an effective separation effect of toxic gases.

[0057] Reference Figures 1 to 11 As shown, the conveying assembly 23 includes an air supply pipe 54, a dispersion pipe 55 and a plurality of branch pipes 56.

[0059] Reference Figures 1 to 11As shown, the pressing assembly 28 includes a wedge-shaped turntable 61, a ball 62, a return spring 63 and a baffle 64. The ball 62 is rotatably arranged on one of the slide bars 30 close to the driven wheel 59, the baffle 64 is fixedly arranged on one of the slide bars 30 close to the driven wheel 59, the return spring 63 is sleeved on one of the slide bars 30 close to the driven wheel 59, a limit plate is fixedly arranged on the outer wall of the L-shaped plate, the baffle 64 and the limit plate respectively contact with the two ends of the return spring 63, the wedge-shaped turntable 61 is fixedly arranged on the hinge shaft, the outer wall of one end of the wedge-shaped turntable 61 is in contact with the outer edge of the ball 62, a conical guide shell 65 is fixedly arranged on the inner wall of the tank body 12, and a liquid delivery pipe 66 is fixedly arranged at the bottom of the conical guide shell 65. When the hinge shaft rotates, due to the wedge The wedge-shaped turntable 61 is fixedly connected to the hinge shaft. In the initial state, the outer wall of the narrow section of the wedge-shaped turntable 61 fits with the ball 62, so that the long section and the narrow section of the wedge-shaped turntable 61 are swapped, and the long section is used to resist the ball 62. Since the ball 62 is rotatably connected to one of the slide bars 30 close to the driven wheel 59, the filter frame 27 is slidably connected to the inside of the tank body 12 through two slide bars 30, and then the filter frame 27 is pushed horizontally through one of the slide bars 30 to achieve the shaking of the filter frame 27, which can throw off the acidic water adhering to the surface of the activated carbon 26, improve the recovery efficiency of the acidic water, and avoid waste of resources. When the lifting rod 48 drives the conical sealing plug 49 to reset, the reset spring 63 cooperates with the baffle 64 to drive one of the slide bars close to the driven wheel 59 to reset.

[0060] Reference Figures 1 to 11 As shown, an exhaust pipe 67 is fixedly provided on the outer wall of the top cover 11, and a drain pipe 68 is fixedly provided at the bottom of the tank body 12. The toxic gas separated from the acidic water is discharged from the exhaust pipe 67, and the acidic water after the toxic gas is removed falls into the interior of the conical guide shell 65, and falls into the interior of the frame through the liquid delivery pipe 66 at the bottom center thereof. An opening is provided at the bottom of the filter frame 27, and the activated carbon 26 in the filter frame 27 filters the acidic water after the toxic gas is removed, and absorbs organic matter, heavy metal ions, suspended impurities and pigments in the acidic water. The acidic water treated with the activated carbon 26 falls into the drain pipe 68 at the bottom of the tank body 12 from the opening at the bottom of the filter frame 27, and is discharged from the exhaust pipe 67 after degassing, oil removal, toxic gas removal and filtration, thereby realizing the recycling of beneficial water.

[0061] The working principle of the present invention is as follows: when acidic water is recovered, the acidic water is first degassed through a degassing tank (not shown in the figure) to remove low-carbon hydrocarbons in the acidic water, to prevent the recovery tank from processing acidic water and causing equipment damage or even explosion, and to improve the safety of recovery. The degassed acidic water is input into a deoiler (not shown in the figure) for deoiling to prevent the subsequent acidic water from destroying the gas-liquid balance in the recovery tank due to oil content, resulting in operational disorder and affecting the treatment efficiency. The end of the liquid inlet pipe 13 away from the top cover 11 is connected to the output end of the deoiler, so that the deoiled acidic water enters the interior of the conical guide pipe 14 through the liquid inlet pipe 13 and the liquid inlet port, and the discharge pipe 32 It is fixedly connected to the discharge port at the bottom of the conical guide shell 65, the butt joint pipe 33 is rotatably connected to the support shell 31 through a bearing 35, the support shell 31 is fixedly connected to the conical guide shell 65, the discharge pipe 32 is inserted into the inside of the butt joint pipe 33, and the diameter of the discharge pipe 32 is smaller than the diameter of the butt joint pipe 33, the four liquid outlet pipes 34 are designed with equal intervals, and the butt joint pipe 33 is connected to the four liquid outlet pipes 34, so that the acidic water falling from the butt joint pipe 33 to the four liquid outlet pipes 34 will use the inertia of the outflow of the acidic water to drive the four liquid outlet pipes 34 to rotate when entering the top of the first evacuation plate 16, thereby realizing the uniform transportation of the acidic water to the first evacuation plate 16.

[0062] When the acidic water is uniformly transported from the four rotating liquid outlet pipes 34 to the water receiving trough at the top of the first evacuation plate 16, the conical water receiving holes 36 on the first evacuation plate 16 disperse the batch of acidic water in the water receiving trough into a plurality of thin streams, which are transported to the top of the second evacuation plate 17 through the cylindrical vent holes 37. At the same time, the high-temperature steam entering from the input pipe 53 enters the transport channel 52 through the gap between the circulation ring 50 and the conical sealing plug 49, and enters the air inlet pipe 21, and then passes through the air inlet pipe 21, the air delivery pipe 54, the dispersion pipe 55, the plurality of branch pipes 56 and the plurality of air outlet heads 25 in sequence, and is transported from bottom to top inside the tank body 12 until it passes through the plurality of cylindrical vent holes 37 at the bottom of the second evacuation plate 17. And it is discharged through several conical water receiving holes 36 on the second evacuation plate 17 to contact with the acidic water dripping from the first evacuation plate 16, and the volatile poisonous gas in the acidic water is diffused into the steam in contact with it, such as poisonous gases such as ammonia, hydrogen sulfide and carbon dioxide. It should be noted that the conical water receiving holes 36 and the cylindrical air vents 37 on the second evacuation plate 17 are designed to be larger than the conical water receiving holes 36 and the cylindrical air vents 37 on the first evacuation plate 16, in order to facilitate the acidic water to drip in a thin stream, while the high-temperature steam rises in a large stream, so as to achieve the wrapping of the thin stream of acidic water by the high-temperature steam, thereby improving the contact effect of steam on the acidic water, and quickly extracting the poisonous gas in the acidic water, which is beneficial to improving the treatment efficiency.

[0063] The poisonous gas separated from the acidic water is discharged from the exhaust pipe 67, and the acidic water after the poisonous gas is removed falls into the interior of the conical guide shell 65, and falls into the interior of the frame through the liquid delivery pipe 66 at the bottom center thereof. An opening is provided at the bottom of the filter frame 27, and the activated carbon 26 in the filter frame 27 filters the acidic water after the poisonous gas is removed, and absorbs organic matter, heavy metal ions, suspended impurities and pigments in the acidic water. The acidic water treated with the activated carbon 26 falls into the drain pipe 68 at the bottom of the tank body 12 through the opening at the bottom of the filter frame 27, and is discharged from the exhaust pipe 67 after degassing, oil removal, poisonous gas removal and filtration, thereby realizing the recycling of beneficial water.

[0064] When the ORP sensor 41 detects that the acidic water entering the liquid inlet pipe 13 has a high degree of contamination, the amount of high-temperature steam that needs to be transported increases, so as to ensure that the high-temperature steam is fully integrated with the acidic water with a high degree of contamination, thereby improving the separation efficiency of the toxic gas. At this time, it is necessary to adjust the distance between the first evacuation plate 16 and the second evacuation plate 17 to reduce the entrainment of mist and foam and avoid affecting the separation effect. Therefore, when it is detected that the acidic water has a high degree of contamination, the electric push rod 38 is started by the controller, so that its output end extends to the end close to the top cover 11. Since its output end is fixedly connected to the push block 39, the push block 39 is fixedly connected to the second evacuation plate 17 through the push rod 40, the top cover 11 and the first evacuation plate 16 are both slidably connected to the push rod 40, and the second evacuation plate 17 is slidably connected to the inside of the tank body 12, and then the second evacuation plate 17 is driven to drop to a certain height through the push rod 40 to prevent the entrainment of mist and foam, which is beneficial to improving the fusion of high-temperature steam and acidic water and improving the separation effect of toxic gases.

[0065] Since the pull rod 42 is fixedly connected to the second evacuation plate 17, the connecting rod 44 is connected to the pull rod 42 through the lifting plate 43, the top cover 11 and the first evacuation plate 16 are both slidably connected to the pull rod 42, and the two insertion rods are fixedly connected to the bottom end of the connecting rod 44. The two rocker arms 45 are rotatably connected to the two support plates through the rotating shaft 47. Each rocker arm 45 is respectively designed with a first slot and a second slot at both ends of the rotating shaft 47, and each first insertion rod 46 is plugged into a first slot. Therefore, when the second evacuation plate 17 slides down, the downward pressure applied by the two first insertion rods 46 in the two first slots forces the two rocker arms 45 to rotate counterclockwise around the rotating shaft 47 as the center.

[0066] Since the lifting rod 48 is slidably connected to the cover shell 20, the conical sealing plug 49 is fixedly connected to the bottom end of the lifting rod 48, and the two second plug rods 51 are fixedly connected to the top of the lifting rod 48, and each second plug rod 51 is plugged into a second slot, and then when the two rocker arms 45 rotate counterclockwise with the rotating shaft 47 as the center, the conical sealing plug 49 is driven by the lifting rod 48 to rise to the top of the circulation ring 50, so that the circulation ring 50 is no longer blocked, thereby increasing the high-temperature steam delivery rate passing through the circulation ring 50, and then increasing the high-temperature steam delivery rate entering the tank body 12, which can reduce the partial pressure in the gas phase, and then promote the volatile components in the acidic water to enter the gas phase more easily, thereby achieving an effective steam stripping effect.

[0067] Each time the rotating shaft 47 drives the two rocking arms 45 to rotate counterclockwise, since the rotating shaft 47 is fixedly connected to one end of the rotating rod 57, the rotating rod 57 is fixedly connected to the driving wheel 58, the driven wheel 59 is rotationally connected to the L-shaped plate through the hinge shaft, and the driving wheel 58 and the driven wheel 59 are connected by a belt 60, thereby driving the hinge shaft to rotate.

[0068] When the hinge shaft rotates, since the wedge-shaped turntable 61 is fixedly connected to the hinge shaft, the outer wall of the narrow section of the wedge-shaped turntable 61 is initially in contact with the ball 62, so that the long section and the narrow section of the wedge-shaped turntable 61 are swapped, and the long section is used to resist the ball 62. Since the ball 62 is rotatably connected to one of the sliding rods 30 close to the driven wheel 59, the filter frame 27 is slidably connected to the inside of the tank body 12 through two sliding rods 30, and then the filter frame 27 is pushed laterally through one of the sliding rods 30 to achieve the shaking of the filter frame 27, which can shake off the acidic water adhering to the surface of the activated carbon 26, thereby improving the recovery efficiency of the acidic water and avoiding waste of resources.
