Abstract
Description
Technical Field
[0001] This invention relates to the field of neopentyl glycol tail gas emergency treatment technology, specifically a neopentyl glycol tail gas emergency treatment device. Background Technology
[0002] The production process of neopentyl glycol generates tail gas containing combustible dust, organic impurities, and unreacted materials. During normal production, this tail gas enters the supporting treatment system for standardized purification. However, when the standardized treatment system experiences a sudden failure and needs to be shut down for maintenance, emergency treatment equipment must temporarily take over the tail gas treatment task to ensure the continuous operation of the production process.
[0003] In actual operation, existing emergency treatment equipment often encounters a problem where sticky polymer particles entrained in neopentyl glycol exhaust gas form a dense filter cake on the filter screen surface, trapping solid contaminants. Due to the stickiness of this dense filter cake, it is often difficult to remove through conventional pulse backflushing. This dense filter cake not only gradually clogs the filter screen pores, reducing exhaust gas treatment efficiency, but also increases the airflow resistance inside the treatment tank, affecting the stability of exhaust gas delivery and failing to meet the requirements for long-term continuous emergency treatment. Furthermore, cleaning the filter screen requires stopping the exhaust gas delivery and disassembling the equipment before cleaning can be carried out, which interrupts emergency treatment work and affects production. Summary of the Invention

[0013] As a further improvement of the present invention: a sealing ring that is rotatably connected to the processing tank is fixedly installed on the outer circumferential surface of the rotating cover.
[0014] As a further improvement of the present invention: the waste centralized treatment structure includes an ash collection hopper fixedly installed at the lower end of the treatment tank, the ash collection hopper being connected to the second absorption and filtration structure, the ash collection hopper being fixedly connected to a protective shell, an active telescopic rod being fixedly installed inside the protective shell, the movable end of the active telescopic rod being fixedly connected to a heat insulation rod slidably connected to the protective shell, the heat insulation rod being fixedly connected to a conical plug movably installed at the middle position of the bottom of the treatment tank, the top of the conical plug being fixedly installed with a bowl-shaped elastic metal cover, and the bowl-shaped elastic metal cover being movably connected to the bottom of the inner side of the treatment tank.

[0016] As a further improvement of the present invention: two sets of brackets are fixedly installed at the lower end of the ash collection hopper.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] During use, this equipment communicates with a remote control center to facilitate remote operation. The mixing section is connected to the exhaust gas supply hose and the gas supply hose. Neopentyl glycol exhaust gas enters the equipment through the rotating mixing section. Rotating the mixing section causes the exhaust gas nozzle and burner to rotate circumferentially along the annular metal filter. The exhaust gas nozzle sprays the exhaust gas out. After passing through the annular metal filter, solid impurities entrained in the exhaust gas are intercepted and filtered. The filtered exhaust gas enters the inner cavity of the treatment tank and then passes through the first absorption and filtration structure before being discharged. The viscous polymer particles in the exhaust gas form a dense and thick filter cake on the inner wall of the annular metal filter. Therefore, the inner wall of the annular metal filter needs to be cleaned. During the cleaning process, the rotating mixing unit drives the first motor to rotate, which in turn drives the heat insulation roller to rotate. The heat insulation roller drives the hooks and metal brush layer to rotate. The metal brush layer first brushes the filter cake on the inner wall of the annular metal filter screen. Because the filter cake itself adheres to the metal brush layer due to the sticky polymer particles, the filter cake is wound off the inner wall of the annular metal filter screen by a winding method. During this process, the hooks grab the filter cake, thereby increasing the pulling and winding effect of the filter cake and preventing the filter cake from slipping off the hooks and metal brush layer during the winding process. As the hooks rotate and the rotating mixing unit drives the heat insulation roller to rotate around the circumference of the annular metal filter screen via the first motor, the wound filter cake adheres to each other layer by layer. At this time, the rotating hooks and metal brush layer roll the filter cake. The filter cake is wound into a filter cake roll, and then an external gas supply device introduces gaseous fuel mixed with oxygen into the rotating mixing section. The gas and exhaust gas mix in the rotating mixing section, ignite, and are ejected from the burner. At this time, the flame closely burns and carbonizes the rotating filter cake roll, while simultaneously treating the exhaust gas at high temperature. The small amount of filter cake residue remaining on the annular metal filter screen is also burned and carbonized by the flame passing around the heat insulation roller. The metal brush layer vibrates due to the periodic impact of the periodic impact on the annular metal filter screen during rotation, which helps to break and fall the carbonized filter cake roll and carbonized residue on the annular metal filter screen. During the flame burning, the airflow is controlled by closing the first absorption and filtration structure and opening the second absorption and filtration structure and the waste collection and treatment structure. Various solid wastes generated during carbonization are blown into a centralized waste treatment structure. The second absorption and filtration structure filters and absorbs the exhaust gas after combustion. After the cleaning operation is completed, the first absorption and filtration structure is opened and the second absorption and filtration structure and the centralized waste treatment structure are closed. The mixing section is rotated to drive the exhaust gas nozzle to spray exhaust gas in a rotating manner, further clearing the mesh of the annular metal filter screen, ensuring the filtration efficiency of the annular metal filter screen, and continuously treating the exhaust gas so that the gas that meets the emission standards is finally discharged. The waste generated during carbonization is temporarily stored in the centralized waste treatment structure for regular unified collection and treatment, avoiding direct discharge of waste and pollution to the environment, and reducing the fugitive emission of harmful exhaust gases.This invention achieves integrated self-cleaning through the coordinated use of a self-cleaning structure, a waste centralized treatment structure, a first absorption and filtration structure, and a second absorption and filtration structure. This allows for the cleaning of filter cake impurities intercepted by the annular metal filter screen without interrupting the exhaust gas supply. No manual shutdown for disassembly and cleaning is required, nor is stopping the exhaust gas supply, ensuring the equipment's continuous and stable emergency handling capabilities. Simultaneously, it efficiently collects and harmlessly treats viscous polymer impurities entrained in neopentyl glycol exhaust gas, preventing impurities from clogging the filter structure and reducing treatment efficiency, and avoiding direct emissions that could cause environmental pollution. It can separately treat the filtered qualified exhaust gas and the waste gas generated during cleaning operations, ensuring that the emitted gas always meets environmental emission standards.

[0028] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0029] Example 1, see Figures 1 to 8 As shown, a new pentylene glycol tail gas emergency treatment device includes a treatment tank 1, an annular metal filter 2 fixedly installed inside the treatment tank 1, and further includes:
[0030] A self-cleaning separation structure 3 is connected to the treatment tank 1. The self-cleaning separation structure 3 includes a rotating gas mixing section 4 connected to the treatment tank 1. The rotating gas mixing section 4 is connected to an exhaust cleaning mechanism 5. The rotating gas mixing section 4 drives the exhaust cleaning mechanism 5 to rotate, guides the exhaust gas from the exhaust cleaning mechanism 5, and mixes the fuel gas and exhaust gas. The exhaust cleaning mechanism 5 includes an exhaust gas nozzle 6 connected to the rotating gas mixing section 4. The outlet pipe of the exhaust gas nozzle 6 is positioned facing the inner wall of the annular metal filter 2. The rotating gas mixing section 4 is connected to a flame head 7, which is used to ignite and spray the mixture of exhaust gas and exhaust gas. The gaseous fuel is used. The flame outlet of the burner head 7 is arranged facing the inner wall of the annular metal filter 2. The rotating mixing part 4 is connected to the first motor 8. The output shaft of the first motor 8 extends into the inner cavity of the processing tank 1. The output shaft of the first motor 8 is fixedly connected to the heat insulation roller 9. Multiple sets of hooks 10 are installed on the circumferential surface of the heat insulation roller 9. Two sets of metal brush layers 11 are fixedly connected to the heat insulation roller 9. The heat insulation roller 9, hooks 10, and metal brush layers 11 are all arranged between the burner head 7 and the annular metal filter 2, which is conducive to the filter cake roll wrapped around the outside of the heat insulation roller 9 contacting the flame core ejected by the burner head 7.
[0031] Waste centralized treatment structure 12 connected to treatment tank 1;
[0032] The first absorption filter structure 13 is connected to the treatment tank 1;
[0033] The second absorption and filtration structure 14 is connected to the waste centralized treatment structure 12. The second absorption and filtration structure 14 has the same structure as the first absorption and filtration structure 13.
[0034] During use, this equipment communicates with a control center that remotely controls the equipment for remote operation. Rotating the mixing section 4 connects the external exhaust gas supply hose and the gas supply hose, allowing neopentyl glycol exhaust gas to enter the equipment. Rotating the mixing section 4 causes the exhaust gas nozzle 6 and the burner head 7 to rotate circumferentially along the annular metal filter 2. The exhaust gas nozzle 6 sprays the exhaust gas out. After passing through the annular metal filter 2, solid impurities entrained in the exhaust gas are intercepted and filtered by the annular metal filter 2. The filtered exhaust gas enters the inner cavity of the treatment tank 1, and then passes through the first absorption and filtration structure 13 for absorption and filtration before being discharged. The viscous polymer particles in the exhaust gas form a dense and thick filter cake on the inner wall of the annular metal filter 2, requiring cleaning of the inner wall of the annular metal filter 2. During the cleaning process, the rotating mixing unit 4 drives the first motor 8 to rotate, which in turn drives the heat insulation roller 9 to rotate. The heat insulation roller 9 drives the hooks 10 and the metal brush layer 11 to rotate. The metal brush layer 11 first brushes the filter cake on the inner wall of the annular metal filter screen 2. Because the filter cake itself adheres to the metal brush layer 11 due to the sticky polymer particles, the filter cake is wound off the inner wall of the annular metal filter screen 2 by winding. During this process, the hooks 10 grab the filter cake, thereby increasing the pulling and winding effect on the filter cake and preventing the filter cake from slipping off the hooks 10 and the metal brush layer 11 during the winding process. As the hooks 10 rotate and the rotating mixing unit 4 drives the heat insulation roller 9 to rotate around the circumference of the annular metal filter screen 2 via the first motor 8, the wound filter cake adheres to each other layer by layer. At this time, the rotating... The hook 10 and the metal brush layer 11 wind the filter cake into a filter cake roll. Then, an external gas supply device introduces gaseous fuel mixed with oxygen into the rotating mixing section 4. The gas and exhaust gas mix in the rotating mixing section 4, ignite, and are ejected from the burner head 7. At this time, the flame closely burns and carbonizes the rotating filter cake roll, while simultaneously treating the exhaust gas at high temperature. The small amount of filter cake residue remaining on the annular metal filter screen 2 is also burned and carbonized by the flame of the burner head 7 bypassing the heat insulation roller 9. The metal brush layer 11 vibrates due to periodic impacts on the annular metal filter screen during rotation, which helps to break and fall the carbonized filter cake roll and carbonized residue on the annular metal filter screen 2. During the flame burning, the first absorption and filtration structure 13 is closed and the second absorption and filtration structure 14 is opened to collect the waste. The treatment structure 12 works by blowing various solid wastes generated during carbonization into the waste collection and treatment structure 12 via airflow. The second absorption and filtration structure 14 filters and absorbs the exhaust gas after combustion. After the cleaning operation is completed, the first absorption and filtration structure 13 is opened and the second absorption and filtration structure 14 and the waste collection and treatment structure 12 are closed. The mixing section 4 rotates, causing the exhaust gas nozzle 6 to rotate and spray exhaust gas again, further clearing the mesh of the annular metal filter 2, ensuring the filtration efficiency of the annular metal filter 2, and continuously treating the exhaust gas. This ensures that the gas meeting emission standards is finally discharged. The waste generated during carbonization is temporarily stored in the waste collection and treatment structure 12 for regular and unified collection and treatment, avoiding direct discharge of waste that could pollute the environment.This also reduces the fugitive emission of harmful exhaust gases. The present invention achieves integrated self-cleaning through the coordinated operation of the self-cleaning structure 3, the waste centralized treatment structure 12, the first absorption and filtration structure 13, and the second absorption and filtration structure 14. This integrates winding collection, carbonization, and material sweeping for self-cleaning, enabling the cleaning of filter cake impurities intercepted by the annular metal filter screen 2 without stopping exhaust gas delivery. No manual shutdown for disassembly and cleaning is required, nor is stopping exhaust gas delivery necessary, ensuring continuous and stable emergency handling capabilities. Simultaneously, it efficiently collects and harmlessly treats viscous polymer impurities entrained in neopentyl glycol exhaust gas, preventing impurities from clogging the filter structure and reducing treatment efficiency, and avoiding direct emission of impurities that would cause environmental pollution. It can separately treat the filtered qualified exhaust gas and the waste gas generated during cleaning operations, ensuring that the emitted gas always meets environmental emission standards.
[0035] In one embodiment, the heat insulation roller 9 has a hollow honeycomb structure inside. The hollow honeycomb structure can effectively reduce the overall weight of the heat insulation roller 9, reduce the load pressure on the first motor 8 during operation, and at the same time improve the heat insulation effect of the heat insulation roller 9, prevent the high temperature generated by flame burning from being transferred to the first motor 8 in large quantities, ensure the long-term stability of the first motor 8, and extend its service life.
[0036] In one embodiment, the rotating gas mixing unit 4 includes a support frame 15 fixedly connected to the treatment tank 1. A second motor 16 is fixedly connected to the support frame 15. A gear 17 is fixedly connected to the output shaft of the second motor 16. The gear 17 meshes with a gear ring 18. A rotating cover 19 is coaxially fixedly connected to the gear ring 18. The rotating cover 19 is rotatably disposed at the upper end of the annular metal filter screen 2. The rotating cover 19 is rotatably mounted at the upper end of the treatment tank 1. The rotating cover 19 is fixedly connected to the exhaust gas nozzle 6 and the flame head 7. A mixing chamber 20 is fixedly connected to a rotating cover 19. A first control valve 21 is fixedly installed at the bottom of the mixing chamber 20. The first control valve 21 is fixedly connected to a first air pipe 22 that is connected to the exhaust gas nozzle 6. A second control valve 23 is fixedly installed at the bottom of the mixing chamber 20. The second control valve 23 is fixedly connected to a second air pipe 24 that is connected to the flame head 7. A pressure probe 25 is fixedly connected to the mixing chamber 20. A first connector 27 is connected to the top of the mixing chamber 20 through a first one-way valve 26. A second connector 29 is connected to the mixing chamber 20 through a second one-way valve 28. During normal filtration operations, neopentyl glycol exhaust gas is connected to the first connector 27 via an external exhaust gas supply hose and then introduced into the mixing chamber 20 via the first one-way valve 26. At this time, the first control valve 21 remains open, and the second control valve 23 remains closed. The exhaust gas in the mixing chamber 20 is then delivered to the exhaust gas nozzle 6 via the first gas pipe 22, completing the normal filtration and delivery of the exhaust gas. The pressure probe 25 can monitor the inlet pressure inside the mixing chamber 20 in real time, allowing operators to adjust the inlet flow rate based on the pressure data and prevent safety issues caused by abnormal pressure. When self-cleaning operations are required, the external gas supply hose delivers gaseous fuel through the second connector 29 and the second one-way valve 28. The feed and oxygen are introduced into the mixing box 20. After the fuel gas is mixed with the exhaust gas in the mixing box 20, the second control valve 23 is opened. The mixed fuel gas is delivered to the burner head 7 through the second gas pipe 24 and sprayed out. After ignition at the burner head 7, continuous and stable combustion can be achieved. During the operation, the second motor 16 drives the gear 17 to rotate. The gear 17 meshes and drives the gear ring 18 to rotate, which in turn drives the rotating cover 19 to rotate relative to the treatment tank 1. The maximum rotation angle of the rotating cover 19 does not exceed 360 degrees, so that the exhaust gas nozzle 6 and the burner head 7 can move at a uniform speed along the circumference of the annular metal filter 2, ensuring that every area of the inner wall of the annular metal filter 2 can be cleaned evenly.
[0037] In one embodiment, a sealing ring 30, which is rotatably connected to the treatment tank 1, is fixedly installed on the outer circumferential surface of the rotating cover 19. The sealing ring 30 can effectively fill the gap between the rotating cover 19 and the rotating mating surface of the treatment tank 1, improve the sealing performance at the rotating connection, prevent exhaust gas from leaking from the mating gap, and prevent substandard exhaust gas from being directly discharged into the atmosphere and causing pollution.
[0038] In one embodiment, the waste centralized treatment structure 12 includes a ash collection hopper 31 fixedly installed at the lower end of the treatment tank 1. The ash collection hopper 31 is connected to the second absorption and filtration structure 14. A protective shell 32 is fixedly connected to the ash collection hopper 31. An active telescopic rod 33 is fixedly installed inside the protective shell 32. A heat insulation rod 34 that is slidably connected to the moving end of the active telescopic rod 33 is fixedly connected to the heat insulation rod 34. A conical plug 35 that is movably installed at the middle position of the bottom of the treatment tank 1 is fixedly connected to the heat insulation rod 34. The conical plug 35 is used to fit and seal the material discharge port at the bottom of the treatment tank 1. A bowl-shaped elastic metal cover 36 is fixedly installed on the top of the conical plug 35. The bowl-shaped elastic metal cover 36 is movably connected to the bottom of the inner side of the treatment tank 1. During normal filtration operations, the conical plug 35 remains in the sealed position, and the top bowl-shaped elastic metal cover 36 adheres to the bottom surface of the inner side of the sealed treatment tank 1 and is in a state of compression deformation, so that the filtered exhaust gas can only enter the first absorption and filtration structure 13 along the inner cavity of the treatment tank 1, and then the exhaust gas is discharged after adsorption and purification. When the self-cleaning operation is started and carbonized waste accumulates at the bottom of the treatment tank 1, the active telescopic rod 33 pushes the heat insulation rod 34 to move the conical plug 35 upward, and the bowl-shaped elastic metal cover 36 moves upward accordingly. A gap is created between the discharge port and the conical plug 35 for the passage of the gas after combustion and the crushed waste. The carbonized waste slides down along the gap into the ash collection hopper 31 for centralized temporary storage, avoiding the accumulation of fragments that will affect the subsequent operation of the equipment. The gas after combustion is discharged through the second absorption and filtration structure 14. After the self-cleaning operation is completed, the active telescopic rod 33 pulls the conical plug 35 to reset, and the bowl-shaped elastic metal cover 36 is pressed tightly against the bottom of the inner side of the treatment tank 1 again, sealing the discharge port again, ensuring the stability of the airflow path during normal filtration operations.
[0039] In one embodiment, both the first absorption and filtration structure 13 and the second absorption and filtration structure 14 include a third control valve 37. The third control valve 37 is fixedly connected to a housing 38. An activated carbon absorption layer 39 is disposed inside the housing 38. Both ends of the activated carbon absorption layer 39 are provided with interception mesh plates 40 fixedly installed inside the housing 38. The third control valve 37 of the first absorption and filtration structure 13 is threadedly connected to the treatment tank 1, and the third control valve 37 of the second absorption and filtration structure 14 is threadedly connected to the ash collection hopper 31. When the first absorption filter structure 13 and the second absorption filter structure 14 are in use, the intercepting mesh plate 40 can limit and fix the activated carbon absorption layer 39, preventing the activated carbon particles from shifting with the airflow. At the same time, it can also intercept fine carbon powder particles entrained in the airflow, preventing carbon powder from entering the atmosphere with the exhaust gas and causing secondary pollution. The threaded connection makes it easy to remove the first absorption filter structure 13 and the second absorption filter structure 14 as a whole to replace or regenerate the activated carbon absorption layer 39, reducing the difficulty of equipment maintenance and improving the efficiency of maintenance operations. Furthermore, by controlling the opening and closing of the third control valve 37, the on / off state of the first absorption filter structure 13 and the second absorption filter structure 14 can be controlled. Combined with the self-cleaning operation, the airflow path can be switched without changing the overall operating state of the equipment, ensuring that the exhaust gas treatment operation can be carried out continuously and without interruption.
[0040] In one embodiment, both the first motor 8 and the second motor 16 are coated with a heat-insulating coating. This coating can block the high temperatures transmitted from inside the treatment tank 1, preventing the high temperatures from continuously affecting the motor's circuitry and mechanical structure, further improving the long-term stability of the motor and reducing the probability of motor failure under high-temperature conditions.
[0041] Example 2, based on Example 1, see [link / reference] Figures 1-3 Two sets of brackets 41 are fixedly installed at the lower end of the ash collection hopper 31. The two sets of brackets 41 provide stable support for the ash collection hopper 31, and at the same time, they provide sufficient operating space to allow air to flow through from below the ash collection hopper 31, thereby assisting in cooling the waste residue inside the ash collection hopper 31.
