Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, in particular to a device for coordinated catalytic treatment of acrylonitrile waste gas and waste liquid. Background Art

[0002] Acrylonitrile is an organic compound with the chemical formula C 3 H 3 N is a colorless liquid with a pungent odor. It is flammable. Its vapor can form an explosive mixture with air. It is easy to burn when exposed to open flames or high heat, and release toxic gases. It reacts violently with oxidants, strong acids, strong alkalis, amines, and bromine. It is mainly used in the manufacture of polyacrylonitrile, nitrile rubber, dyes, synthetic resins, and medicines.

[0003] The waste gas and waste water generated after the acrylonitrile operation do not meet the requirements of normal discharge, and thus the waste gas and waste water generated need to be treated. In this regard, the relevant patent discloses a method for treating acrylonitrile waste liquid (Announcement No.: CN114031230B). Usually, the waste gas and waste water are treated separately. The waste gas is treated by an AOGC device. When the AOGC device fails, the waste gas in the combustion chamber cannot be burned, while the supply of waste gas continues, thereby causing the internal pressure to exceed the pressure that the equipment can withstand, resulting in damage to the equipment and leakage of waste gas. The present application is aimed at waste water and waste gas and works in coordination to avoid damage to AOGC and leakage of waste gas.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0046] For example, see Figure 1-Figure 12 , a device for the coordinated catalytic treatment of acrylonitrile waste gas and waste liquid, comprising a liquid combustion tank 12, a plurality of support rods are fixed at the bottom of the liquid combustion tank 12, the liquid combustion tank 12 is installed at a designated position through the support rods, and the figure shows that a fourth delivery pipe 6 connected to the liquid combustion tank 12 is fixed on one side thereof, and a third delivery pipe 5 and a fifth delivery pipe 7 connected to the fourth delivery pipe 6 are respectively fixed on both sides thereof, the third delivery pipe 5 is connected to the liquid combustion tank 12, an adsorption assembly is installed on the side of the liquid combustion tank 12 away from the fourth delivery pipe 6, the adsorption assembly is connected to the fourth delivery pipe 6 through the fifth delivery pipe 7, the fourth delivery pipe 6 is in the shape of a "cross" through the third delivery pipe 5 and the fifth delivery pipe 7, and a coordination mechanism is installed on both sides of the fifth delivery pipe 7 and the third delivery pipe 5 on the fourth delivery pipe 6;

[0047] The gas combustion tank 10 is fixed on the side of the gas combustion tank 10 away from the fourth delivery pipe 6, and the gas combustion tank 10 is also connected to the adsorption component through the sixth delivery pipe 9. The liquid combustion tank 12 and the gas combustion tank 10 are both installed with processing components.

[0048] Furthermore, the liquid combustion tank 12 is connected to the combustion chamber of the AOGC device 1 through the fourth delivery pipe 6. A pump body 3 is fixed to the side of the liquid combustion tank 12 facing the AOGC device 1. The input port of the pump body 3 is connected to the sewage discharge port of the AOGC device 1 through the first delivery pipe 2. The discharge port of the pump body 3 is connected to the liquid combustion tank 12 through the second delivery pipe 4. When the pump body 3 is working, the wastewater discharged by the AOGC device 1 is transported to the liquid combustion tank 12 through the first delivery pipe 2 and the second delivery pipe 4, and then processed by the processing component.

[0049] When a combustion chamber of the AOGC device 1 fails, the coordination mechanism is triggered, and when the coordination mechanism works, the exhaust gas is transported to the treatment component through the fourth delivery pipe 6, and is temporarily treated by the treatment component;

[0050] It should also be noted that the AOGC device uses catalytic oxidation and catalytic reduction technology to treat acrylonitrile tail gas, converting harmful substances such as acrylonitrile, acetonitrile, propylene, nitrogen oxides, etc. in the tail gas into water, carbon dioxide, nitrogen and other substances that can be directly discharged, while recovering the reaction heat, achieving the purpose of energy saving and environmental protection. This device is considered to be a relatively mature existing technology and will not be elaborated on in detail here.

[0051] The processing assembly includes a liquid separation box 13 fixed to the inner wall of the liquid combustion tank 12, and a plurality of atomizing nozzles connected to the liquid separation box 13 are fixed on the bottom circumference thereof, and the liquid separation box 13 is connected to the second delivery pipe 4;

[0052] A fuel spraying member 18 is also fixed to the inner wall of the liquid combustion tank 12 at one end away from the liquid separation box 13, and the fuel spraying member 18 is connected to the feeding mechanism;

[0053] A catalytic cylinder 15 is coaxially fixed in the gas combustion tank 10, and a flow divider 14 with tapered ends is arranged in the catalytic cylinder 15, and the flow divider 14 and the catalytic cylinder 15 are fixed by a catalytic element 16;

[0054] A heat receiving member 17 is also provided between the liquid separation box 13 and the fuel spraying member 18 in the liquid combustion tank 12. The heat receiving member 17 penetrates the gas combustion tank 10 and the liquid combustion tank 12 and is fixed to the catalytic cylinder 15.

[0055] An igniter 11 is also installed in the liquid combustion tank 12 .

[0056] Furthermore, the pump body 3 delivers the waste liquid to the liquid separation box 13 through the second delivery pipe 4, and then the waste liquid is split by the liquid separation box 13 and then sprayed to the fuel spraying member 18 through the atomizing nozzle;

[0057] When the feeding mechanism is working, the fuel is supplied to the fuel spraying member 18, and then the fuel is atomized by the fuel spraying member 18 and sprayed toward the liquid separation box 13. At this time, the sewage and the fuel are both materialized and mixed, and the fuel is ignited by the igniter 11 to burn and produce a combustion reaction. The toxic substances in the acrylonitrile wastewater undergo an oxidative decomposition reaction under high temperature and oxygen-rich environment. Toxic substances, such as acrylonitrile, are completely oxidized and decomposed into harmless or low-toxic substances, such as carbon dioxide, nitrogen and water vapor, etc., which can be simply understood as similar to gasification;

[0058] The gas generated after combustion is transported to the adsorption assembly through the fourth delivery pipe 6 and the fifth delivery pipe 7, and then transported to the gas combustion tank 10. The catalyst 16 and the catalyst cartridge 15 in the gas combustion tank 10 are similar to the three-way catalytic converter of the car. Although the structures are slightly different, they are basically the same. The diverter 14 plays a diverting role. The gas and liquid generated after being processed by the catalyst 16 can meet the emission requirements. The liquid and gas are discharged or transported to the subsequent process through the discharge port opened at the tail end of the gas combustion tank 10.

[0059] As is known to all, the three-way catalytic reaction needs to be carried out at a certain temperature, that is, it needs to be heated. When the liquid is burned in the liquid combustion tank 12, a large amount of heat will be generated, and the heat will be absorbed by the heat receiving element 17 and transferred to the catalytic tube 15 and the catalytic element 16.

[0060] The adsorption assembly includes a processing box 8, in which a bubble tube arranged in an "L" shape is fixed. The bubble tube is connected to the fifth conveying pipe 7. The bubble tube is located at one end away from the fifth conveying pipe 7 and has multiple groups of air holes on its circumference. The sixth conveying pipe 9 is connected to the processing box 8.

[0061] Furthermore, the fuel sprayed by the heat receiving member 17 generates certain particles after combustion, and after being transported to the bubble tube through the heat receiving member 17, bubbles are generated at the bottom of the processing box 8 and float upward, and the particles in the gas are adsorbed by water, and then transported to the gas combustion tank 10 through the sixth transport pipe 9;

[0062] It is obvious that a certain amount of water needs to be added into the processing box 8 , and the water level needs to be lower than the connection point between the sixth delivery pipe 9 and the processing box 8 .

[0063] Embodiment 2, the feature that distinguishes the embodiment is that the cooperative mechanism includes two movable parts 19 sealed and slidably installed in the fourth delivery pipe 6, the two movable parts 19 are coaxially rotatably installed with a transmission rod 22 on opposite sides, the transmission rod 22 is sleeved with a transmission cylinder 41 on the outer side, the transmission cylinder 41 is rotatably connected to a support disk 21 fixed to the inner wall of the fourth delivery pipe 6, a spring 26 is installed between the support disk 21 and the movable parts 19, an opening and closing assembly is installed on the two movable parts 19, the opening and closing assembly is connected to a trigger assembly installed on the outer wall of the fourth delivery pipe 6, a cooperative assembly is installed between the two movable parts 19, and the cooperative assembly intermittently cooperates with the two trigger assemblies;

[0064] A blocking component is installed at the fifth delivery pipe 7 and the connection point between the third delivery pipe 5 and the fourth delivery pipe 6, and the trigger component cooperates with the cooperative component.

[0065] Further, for the convenience of description, the connection between the fifth delivery pipe 7 and the third delivery pipe 5 and the fourth delivery pipe 6 is named as a flow splitting portion;

[0066] One of the movable parts 19 and the opening and closing assembly installed on the movable part 19 controls the connection or blocking of the fourth delivery pipe 6 with the AOGC device 1, and the other movable part 19 and the opening and closing assembly control the connection and blocking of the fourth delivery pipe 6 with the liquid combustion tank 12. When the two movable parts 19 are connected with the movable part 19, the gas is delivered to the diversion part;

[0067] The two opening and closing components cannot be opened at the same time. When one is open, the other is closed. The cooperative component is used to achieve this effect.

[0068] The fourth delivery pipe 6 is connected with the fifth delivery pipe 7 or the third delivery pipe 5 through a blocking component, and the work of the blocking component is driven by the work of the coordination component;

[0069] Under normal working conditions, a movable part 19 and an opening and closing assembly controlling the fourth delivery pipe 6 to be connected to the liquid combustion tank 12 will be pushed by the gas pressure in the liquid combustion tank 12, and the trigger assembly will be driven to work when the movable part 19 moves, but the trigger assembly will not be triggered at this time. After the movable part 19 moves to the set stroke, the trigger assembly is triggered, and the opening and closing assembly is quickly driven to work by the trigger assembly, so that the diverter part is connected to the liquid combustion tank 12, and the gas inside it can enter the diverter part through the fourth delivery pipe 6. At the same time, the opening and closing assembly of another assembly is closed by the cooperative assembly. When the cooperative assembly works, the blocking assembly is also driven to work, so that the fourth delivery pipe 6 is connected to the fifth delivery pipe 7;

[0070] Similarly, when the combustion chamber of the AOGC device 1 fails, since the gas continuously / intermittently enters the combustion chamber and cannot be burned and discharged, the internal pressure will gradually increase. At a certain value, the pressure will be greater than the pressure in the liquid combustion tank 12. At this time, the movable member 19 and the opening and closing assembly that control the fourth delivery pipe 6 to be connected with the AOGC device 1 will be opened, and the other movable member 19 and the opening and closing assembly will be closed, and at the same time, the flow diversion cavity of the blocking structure will be connected with the third delivery pipe 5, so that the gas in the AOGC device 1 can be transported to the liquid combustion tank 12 through the third delivery pipe 5 to be burned together with the sewage;

[0071] The opening of the two opening and closing components is based on the pressure in the two combustion chambers;

[0072] Among them, a plurality of transmission bars are fixed at equal intervals on the outer circumference of the transmission rod 22, and the transmission bars are slidably matched with the transmission grooves opened on the inner wall of the transmission cylinder 41, so that the transmission rod 22 and the transmission cylinder 41 can slide axially and rotate synchronously, and the spring 26 can be used to counteract the force of the movable part 19 when it is subjected to pressure movement. When the driving force of the pressure is greater than the potential energy of the spring 26, the movable part 19 moves and compresses the spring 26. After the driving force of the pressure disappears and the elastic potential energy of the spring 26 pushes the movable part 19 to reset.

[0073] The opening and closing assembly includes a blocking disk 20 coaxially fixed to the end of a transmission rod 22, and the blocking disk 20 and the movable member 19 are both provided with discharge ports equidistantly arranged on the side of the blocking disk 20;

[0074] The opening and closing assembly further includes a transmission plate 30 that penetrates the fourth delivery pipe 6 and is sealingly and slidably connected to the fourth delivery pipe 6;

[0075] The transmission plate 30 includes a plate body, a transmission part 35 is provided at one end of the plate body and a rack part 42 is provided at the other end, the rack part 42 cooperates with a third gear 40 coaxially fixed on the transmission cylinder 41, and the transmission part 35 cooperates with the trigger assembly;

[0076] The movable part 19 is fixed with a sealing plate 29, and a rack 33 cooperating with the trigger assembly is fixed with the sealing plate 29; wherein, a slot for the linkage block between the movable part 19 and the sealing plate 29 is provided on the fourth delivery pipe 6, and the slot can be sealed by the sealing plate 29, and the rack 33 can be driven to move when the movable part 19 moves. The connection relationship can be simply understood as follows: the movable part 19 is fixedly connected to the rack 33 through the connecting block, the transmission block passes through the slot, and the sealing plate 29 is fixed on the transmission block and is used to seal the slot, such as Figure 4 and Fig.10 shown.

[0077] Furthermore, when the movable member 19 is subjected to pressure movement, the sealing plate 29 drives the rack 33 to follow the movement. When the movable member 19 and the rack 33 move to the specified position, the rack 33 triggers the cooperation of the transmission component and the transmission part 35 to drive the transmission plate 30 to move vertically. When the transmission plate 30 moves vertically, the transmission cylinder 41 is driven to rotate through the meshing of the transmission belt 32 and the third gear 40. The transmission cylinder 41 drives the transmission rod 22 to rotate through the transmission groove, thereby driving the blocking disk 20 to rotate.

[0078] Among them, because the movable member 19 is fixedly connected to the sealing plate 29, the movable member 19 is limited and guided, so that the movable member 19 cannot rotate and can only move axially toward the fourth delivery pipe 6. When the blocking plate 20 rotates, the discharge port on the blocking plate 20 coincides with the discharge port on the movable member 19, thereby releasing the blockage;

[0079] Similarly, if sealing is required again, the transmission plate 30 is lifted up and the sealing can be achieved by coordinating the directions of the rack portion 42 and the transmission cylinder 41 .

[0080] The trigger assembly includes a second gear 31 rotatably mounted on the outer wall of the fourth delivery pipe 6, the second gear 31 meshes with a rack 33, and a transmission disc 34 cooperating with a transmission part 35 is rotatably mounted on one side of the second gear 31, and the transmission disc 34 and the second gear 31 are connected by a transmission belt 32;

[0081] Among them, the transmission disk 34 includes a disk body, and multiple transmission claws are equidistantly installed on the edge of the disk body. Torsion springs are installed at the rotational connections of the multiple transmission claws. A tension spring 39 is rotatably installed at the eccentric part of the disk body, and the tension spring 39 is rotatably connected to the outer wall of the fourth conveying pipe 6.

[0082] Furthermore, when the rack 33 moves, the second gear 31 is driven to rotate. When the second gear 31 rotates, the transmission disc 34 is driven to rotate through the transmission belt 32. When the transmission disc 34 rotates, the tension spring 39 is driven to rotate and connect with the transmission disc 34 to perform a circular motion around the center of the transmission disc 34. During the movement, the tension spring 39 is pulled up. When the tension spring 39 rotates to the highest point, it continues to rotate around the circumference of the transmission disc 34. The elastic potential energy stored during the pulling up will be quickly released, and then the transmission disc 34 is driven to rotate quickly by the power of the tension spring 39 when the elastic potential energy is released.

[0083] The centrifugal force during rapid loading causes the transmission claw to swing away, and the transmission claw engages with the transmission part 35 of the transmission plate 30 to drive the transmission plate 30 to move vertically downward. When the transmission plate 30 moves downward, the transmission rod 22, the third gear 40, and the blocking disk 20 rotate to release the seal through the cooperation between the rack part 42 and the transmission cylinder 41.

[0084] Among them, as mentioned above, the movement of the movable part 19 is based on the pressure push, and after the sealing disk 20 rotates to release the seal, the driving force of the pressure will gradually decrease until it reaches a balance, and the movable part 19 will compress the spring 26 when being pushed, so that the spring 26 reserves elastic potential energy. When the driving force of the pressure disappears, the elastic potential energy of the spring 26 is released to drive the movable part 19 to move back and forth, and then drive the rack 33 to move back and forth, thereby driving the second gear 31 and the transmission disk 34 to rotate in the opposite direction. When the transmission disk 34 rotates in the opposite direction, the transmission of the transmission disk 34 is released from the engagement with the transmission part 35, so that the transmission claw, the movable part 19, and the rack 33 are all returned to the initial state for the next use. On the premise of having the ability of instantaneous triggering, this component can be reset to the initial state after the trigger is completed, and has high practicality.

[0085] The cooperative assembly includes two oblique blocks 36 slidably mounted on the outer wall of the fourth delivery pipe 6, the two oblique blocks 36 are directly fixed by a connecting plate 28, and the connecting plate 28 passes through the fifth delivery pipe 7 and is sealed and slidably connected to the fifth delivery pipe 7;

[0086] The two transmission plates 30 are both fixed with a second force-bearing portion 38 matched with the oblique block 36 , and the two processing boxes 8 are both fixed with a first force-bearing portion 37 matched with the rack 33 .

[0087] Furthermore, the movement of the rack 33 is achieved by the first force-bearing portion 37 pushing one of the inclined blocks 36 to follow the movement, and at the same time, the connecting plate 28 drives the other inclined block 36 to follow the synchronous movement, so that when one of the racks 33 pushes the inclined block 36 through the first force-bearing portion 37, the two inclined blocks 36 move in the opposite direction toward the other rack 33, and vice versa when the other rack 33 pushes;

[0088] When one of the racks 33 pushes the inclined block 36 to move in the opposite direction of the other rack 33, the transmission plate 30 will be driven to rise vertically through the cooperation of the second force-bearing portion 38 of the inclined block 36. The rise of the transmission plate 30 will drive the transmission cylinder 41 to rotate in the opposite direction through the cooperation of the rack portion 42 and the third gear 40, thereby driving the blocking plate 20 to rotate in the opposite direction, so that the discharge port on the blocking plate 20 is misaligned with the discharge port on the movable member 19, thereby sealing;

[0089] In short, the movement of the rack 33 is to trigger the trigger assembly to open the opening and closing assembly below so that it can communicate with the diversion part. At this time, the stability of the rack 33 will close the other opening and closing assembly through the cooperation of the oblique block 36 and the second force-bearing part 38.

[0090] The two opening and closing components will not be in the open state at the same time. When one of them is opened, the other one will definitely be closed.

[0091] The plugging assembly includes a threaded rod 25 rotatably mounted in the fifth delivery pipe 7, a threaded barrel 24 threadedly matched with the threaded rod 25 is sleeved on the outer side of the threaded rod 25, a plugging member 23 is fixed to the end of the threaded barrel 24, and the plugging member 23 is sealingly and slidably matched with the fifth delivery pipe 7 and the third delivery pipe 5;

[0092] A first gear 27 is coaxially fixed on the threaded rod 25 , and the first gear 27 is meshed with a rack plate disposed on the connecting plate 28 .

[0093] Furthermore, when the two oblique blocks 36 move, the connecting plate 28 moves together, and when the connecting plate 28 moves, the first gear 27 is driven to rotate through the rack plate, and when the first gear 27 rotates, the blocking member 23 is driven to rise / fall vertically through the threaded engagement with the threaded barrel 24;

[0094] The blocking member 23 serves the purpose of switching the connection. When the blocking member 23 is vertically lowered, the fifth delivery pipe 7 is connected with the fourth delivery pipe 6. When the blocking member 23 is raised, the third delivery pipe 5 is connected with the fourth delivery pipe 6.

[0095] It should also be noted that the movement of the connecting plate 28, that is, one of the movable parts 19 is in a moving state, corresponds to the need to open a corresponding locking component and close another opening and closing component, and at the same time, switch the connection state.

[0096] In summary, under normal conditions, the pressure in the liquid combustion tank 12 must be greater than the pressure in the AOGC device 1, and the fourth delivery pipe 6 is in a connected state with the liquid combustion tank 12, and the gas generated in the liquid combustion tank 12 will be first delivered to the diversion part through the fourth delivery pipe 6. At this time, the AOGC device 1 and the fourth delivery pipe 6 are not connected, and at the same time, the blocking member 23 is in a descending state, and the gas will be discharged through the fifth delivery pipe 7;

[0097] When a fault occurs in the AOGC device 1, its internal pressure increases, and its pressure will gradually become greater than the pressure in the liquid combustion tank 12. At this time, the connection between the fourth delivery pipe 6 and the AOGC device 1 is opened, and the liquid combustion tank 12 and the fourth delivery pipe 6 are blocked at the same time, and the blocking member 23 is driven to rise, and the gas will be discharged into the liquid combustion tank 12 through the third delivery pipe 5.

[0098] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
