Description

Technical Field

[0001] The invention relates to the technical field of chemical waste gas treatment, in particular to a waste gas treatment device for a chemical reactor. Background Art

[0002] Chemical waste gas refers to toxic and harmful gases discharged by chemical plants during chemical production. Chemical waste gas often contains many types of pollutants with complex physical and chemical properties and different toxicities. It seriously pollutes the environment and affects human health. The composition of chemical waste gas generated by different chemical production industries varies greatly.

[0003] According to a publicly disclosed waste gas treatment device for a chemical reactor (Announcement No.: CN222468484U), in the above application, when the top rod moves downward, the sliding rod and the blocking block move downward accordingly, so that the blocking block can block the guide bucket to prevent the water above the guide bucket from being discharged through the guide bucket, so that the entire waste gas treatment device can continue to treat the waste gas, effectively improving the waste gas treatment efficiency.

[0004] However, in the actual use of the above equipment, the waste gas generated by chemical production is generally mixed with a large amount of solid particle impurities and harmful gases. When the chemical waste gas is treated by filtering with a liquid aeration device, if the solid particle impurities are not pre-treated, it is easy to get clogged. The clogging of the filter material during use will also directly affect the device's treatment efficiency of the waste gas. In view of this, we proposed a waste gas treatment device for chemical reactors. Summary of the invention

The return spring is sleeved on the arc-shaped outer surface of the cylindrical part, and both ends of the return spring are fixedly connected to the side wall of the circular piston part and the side wall of the fixed ring respectively.

[0015] Preferably, tooth patterns meshing with the rack and realizing transmission are arranged on the top arc-shaped outer wall of the transmission sleeve, and the inside of the transmission sleeve is hollow to facilitate the installation of the scroll spring.

[0016] Compared with the prior art, the present invention provides an exhaust gas treatment device for a chemical reaction kettle, which has the following beneficial effects:

[0017] 1. For this exhaust gas treatment device for a chemical reaction kettle, when the filter disc is blocked, it will move upward along the inside of the rotating cylinder. Through the puncture of the filter core inside the filter disc by the puncture needle, when encountering relatively stubborn solid impurities, the puncture needle is blocked and moves upward. At this time, under the influence of the convex ball and the spiral chute, the puncture needle rotates self - sufficiently to improve the cleaning effect on the filter disc and its internal filter element, ensure the air permeability of the filter disc, and further ensure the aeration treatment effect of the device on the exhaust gas, thus solving the problem that solid particle impurities in the exhaust gas generated by the production of the chemical reaction kettle are likely to block the filter disc and then affect the normal aeration of the aeration head.

[0018] 2. For the waste gas treatment device used in the chemical reaction kettle, through the settings of the guiding plate and the Y-shaped groove, the puncture needle moves upward due to the obstruction of the impurities inside the rising filter disc. The round rod will move upward along the inner wall of the Y-shaped groove. Since there is no separate guiding structure at the bifurcated part of the top of the Y-shaped groove, when the round rod moves to the top of the Y-shaped groove, it will randomly swing left or right. Thus, during the upward movement of the puncture needle, it will also have a lifting effect. Combined with the rotation of the sliding rod itself, it will produce a kneading and squeezing effect on the filter element in the filter disc, further improving the cleaning efficiency of the accumulated impurities in the filter disc, ensuring the gas passing performance and treatment effect of the waste gas, and thus solving the problem that as the use time increases, solid particles agglomerate and are difficult to clean in a timely and effective manner, and further causing the filter disc to fail to achieve good filtering and air permeability effects.

[0019] 3. For the waste gas treatment device used in the chemical reaction kettle, by setting a pressurizing component, during the process that the filter disc moves upward along the inside of the rotating cylinder under the push of air pressure when it is blocked, the top of the connecting block will contact the proximity switch. When it is triggered, it controls the driving motor to increase the speed by one gear. When the connecting block disengages from the proximity switch, it controls the driving motor to restore the speed. Thus, when the filter disc is blocked and affects the aeration volume of the aeration head, by increasing the speed to drive the aeration pipe and the aeration head to move in the waste gas treatment solution, the diffusion range of the bubbles generated by aeration is expanded, so that it can more fully contact the waste gas treatment solution and complete the waste gas treatment work, and thus solves the problem that the blockage of the filter disc reduces the aeration volume of the aeration head, and further reduces the contact efficiency between the bubbles generated by aeration of the waste gas and the waste gas treatment solution.

[0020] 4. For the waste gas treatment device used in the chemical reaction kettle, when the proximity switch is triggered, the connecting block cooperates with the dial block to release the limit on the clamping block, and the driving motor drives the pinion to rotate at an increased speed. Under the action of centrifugal force, the piston plate moves to the right along the inner surface of the center of the fixed ring to squeeze the space of the piston chamber. Since this change is triggered by the upward movement of the filter disc in the rotating cylinder, at this time, the filter disc is blocked and the airflow entering the aeration pipe is reduced. By pressurizing the air inlet area of the aeration head, that is, the piston chamber, the stable aeration of the aeration head is ensured, so as to ensure the purification and treatment efficiency of the device for the waste gas, and thus solves the problem that due to the blockage of the filter disc, the internal pressure of the aeration head is too small to carry out stable aeration, and further reduces the treatment efficiency of the whole device for the waste gas.

[0021] 5. The waste gas treatment device for this chemical reaction kettle, by setting a swinging component, when the rotating cylinder rotates inside the treatment tank due to the drive of the drive motor, due to the blocking of the leaf plate by the waste gas treatment solution, the aeration head has a tendency to rotate at the bottom of the aeration pipe. Due to the setting of the scroll spring, the aeration head will also perform a reverse rotation movement during the rotation process, thereby further increasing the dispersion range of the small bubbles generated by the aeration head, making the waste gas more fully contact with the waste gas treatment solution, and then improving the treatment effect of chemical waste gas, thus solving the problem that the diffusion path of the bubbles generated by the traditional aeration head in the waste gas treatment solution is relatively fixed, resulting in a relatively low contact efficiency between the waste gas and the waste gas treatment solution and affecting the waste gas treatment efficiency.

[0022] 6. The waste gas treatment device for this chemical reaction kettle, when the piston plate moves towards the side away from the rotating cylinder due to centrifugal force after the pressurizing component is triggered, drives the transmission sleeve through the rack, so that the transmission sleeve deflects by a certain amplitude, thereby limiting the winding state of the scroll spring, and thus can change the maximum winding rotation range of the scroll spring, so that the movement path of the bubbles generated when the aeration head rotates and diffuses bubbles in the waste gas treatment solution is more random, increasing the diffusion range of the bubbles generated by the waste gas in the waste gas treatment solution, ensuring the waste gas treatment efficiency of the device, and thus solving the problem that the diffusion range of the bubbles generated by the traditional aeration head in the waste gas treatment solution is too small and affecting the waste gas treatment efficiency.

Detailed implementation mode

[0031] As Figures 1-7 shown, the present invention provides a technical solution: an exhaust gas treatment device for a chemical reactor, including a treatment tank 1, a fixed sleeve 2 is fixedly installed on the bottom outer wall of the treatment tank 1, an intake pipe 3 is fixedly installed through and on the side wall of the fixed sleeve 2, a rotating cylinder 4 is rotatably installed on the top surface of the fixed sleeve 2, an aeration pipe 5 is fixedly installed on the side wall of the rotating cylinder 4, an aeration head 6 is arranged on the bottom inner wall of the aeration pipe 5, an exhaust pipe 7 is fixedly installed on the top outer wall of the treatment tank 1, and a puncture assembly 8 for preventing the aeration head 6 from being affected by solid impurities in the exhaust gas and reducing the aeration efficiency is arranged inside the rotating cylinder 4. The puncture assembly 8 includes a filter disc 81, a disc 82, a fixed cylinder 83, a slide bar 84, a convex ball 85, a small spring 87, a spiral chute 86, a puncture needle 88, a guide plate 89, a round rod 810 and a Y-shaped groove 811.

[0032] In an embodiment of the present invention, the filter disc 81 is movably installed inside the rotating cylinder 4, a disc 82 is fixedly installed on the inner wall of the rotating cylinder 4, a fixed cylinder 83 is fixedly installed on the upper surface of the disc 82, a slide bar 84 is fixedly installed through and movably on the inner wall of the disc 82, a convex ball 85 is fixedly installed on the arc outer wall of the slide bar 84, a small spring 87 is arranged between the top end of the slide bar 84 and the top inner wall of the fixed cylinder 83, a spiral chute 86 is opened on the arc inner wall of the fixed cylinder 83, the bottom end of the slide bar 84 is hinged with a puncture needle 88, a guide plate 89 is rotatably installed on the lower surface of the disc 82, a round rod 810 is fixedly installed on the arc outer wall of the top of the puncture needle 88, a Y-shaped groove 811 is opened on the inner wall of the guide plate 89, and the round rod 810 is arranged inside the Y-shaped groove 811.

[0033] Specifically, a detachable sealing cover is provided at the bottom of the fixed sleeve 2, so that while ensuring the sealing performance during normal use of the fixed sleeve 2, it can be opened and cleaned after a certain amount of solid impurities accumulate at the bottom of the fixed sleeve 2, ensuring the stable operation of the entire system. At the same time, one end of the intake pipe 3 far from the fixed sleeve 2 is connected in a through manner with the exhaust structure of the chemical reaction kettle. Further, the inside of the rotating cylinder 4, the air diffuser pipe 5, and the fixed sleeve 2 are connected in a through manner, so that the waste gas discharged from the exhaust structure of the chemical reaction kettle can finally be discharged into the inner cavity of the treatment tank 1 through the fixed sleeve 2, the rotating cylinder 4, and the air diffuser pipe 5 and then through the air diffuser head 6. And during the treatment of chemical waste gas, sufficient waste gas treatment solution is injected into the inside of the treatment tank 1, and the filter disc 81 in the puncture assembly 8 is used to block and drop the solid impurities in the waste gas. The aerated waste gas moves upward after being absorbed by the waste gas treatment solution and finally is discharged outward through the exhaust pipe 7. And the end of the exhaust pipe 7 is connected to the chemical treatment equipment, so that the preliminarily treated waste gas enters the subsequent treatment process, reducing the environmental pollution caused by the emission of chemical waste gas.

[0034] Further, please refer to the attached drawings of the specification Figures 3-5 . Square blocks are provided on the left and right sides of the filter disc 81, and rectangular grooves adapted to the above-mentioned square blocks are formed on the arc-shaped inner wall of the rotating cylinder 4, so that when the filter disc 81 is blocked after a period of filtering operation, it can move upward inside the rotating cylinder 4 along the inner surface of the rectangular groove. At the same time, a disc 82 is arranged above the filter disc 81, and the number of the fixed cylinders 83, the sliding rods 84, the small springs 87, and the puncture needles 88 is set in several groups, and several groups of the fixed cylinders 83, the sliding rods 84, the small springs 87, and the puncture needles 88 are evenly distributed inside the disc 82, so that the puncture needles 88 can perform a more comprehensive puncture cleaning work on the filter disc 81, and then realize the puncture cleaning of the particulate impurities accumulated inside the filter element placed in the filter disc 81. Specifically, a convex ball 85 is arranged in the spiral chute 86, so that when the sliding rod 84 moves vertically inside the fixed cylinder 83, through the guidance and restriction of the convex ball 85 and the spiral chute 86, the sliding rod 84 is driven to rotate. In addition, an inverted T-shaped groove is arranged at the top of the sliding rod 84, and the bottom end of the small spring 87 is fixedly connected with a T-shaped disc adapted to the above-mentioned inverted T-shaped groove, and the T-shaped disc is arranged in the inverted T-shaped groove, so that the small spring 87 can push the sliding rod 84 vertically without causing movement interference to the rotation of the sliding rod 84.

[0035] Meanwhile, two sets of guiding plates 89 are provided, and the two sets of guiding plates 89 are mirror - installed on the left and right sides of the puncture needle 88. An annular connecting piece is provided at the top ends of the two sets of guiding plates 89. The two sets of guiding plates 89 are rotatably installed on the lower surface of the disc 82 through this annular connecting piece, and the sliding rod 84 is arranged at the center of this annular connecting piece. Further, the bifurcated section of the Y - shaped groove 811 is arranged on the side close to the disc 82. As the use time of the filter disc 81 increases, the bottom surface thereof will be blocked by solid impurities. Under the continuous input of waste gas, the air pressure inside the rotating cylinder 4 increases, so that the filter disc 81 moves upward along the inside of the rotating cylinder 4. Through the puncture of the filter core inside the filter disc 81 by the puncture needle 88, when encountering relatively stubborn solid impurities, the puncture needle 88 is blocked and moves upward. At this time, under the influence of the convex ball 85 and the spiral chute 86, the puncture needle 88 rotates self - rotatably to improve the cleaning effect on the filter disc 81 and its internal filter element, ensure the air permeability of the filter disc 81, and further ensure the aeration treatment effect of the device on waste gas. Specifically, through the arrangement of the guiding plate 89 and the Y - shaped groove 811, the puncture needle 88 is blocked by the impurities inside the rising filter disc 81 and moves upward, and the round rod 810 will move upward along the inner wall of the Y - shaped groove 811. Since no separate guiding structure is provided at the bifurcated part at the top of the Y - shaped groove 811, when the round rod 810 moves to the top of the Y - shaped groove 811, it randomly swings left or right, so that the puncture needle 88 will also have a picking - up effect during the upward movement process. Cooperating with the self - rotation of the sliding rod 84, it produces a kneading and squeezing effect on the filter element inside the filter disc 81, further improving the cleaning efficiency of the accumulated impurities on the filter disc 81 and ensuring the gas passing performance and treatment effect of waste gas.

[0036] Please refer to the attached drawings of the specification Figure 3 and Figure 6 , a pressurizing component 9 for preventing the insufficient air pressure of the aeration head 6 from reducing the aeration treatment efficiency of waste gas is arranged inside the aeration pipe 5. The pressurizing component 9 includes a driving motor 91, the driving motor 91 is fixedly installed on the bottom outer wall of the treatment tank 1, the output end of the driving motor 91 is fixedly installed with a small gear 92, a large gear 93 is fixedly installed through and on the outer wall of the rotating cylinder 4, a connecting block 94 is fixedly installed on the arc - shaped outer wall of the filter disc 81, a dialing block 95 is fixedly installed on the upper surface of the connecting block 94, a piston cavity 912 is opened on the inner wall of the aeration pipe 5, a fixed ring 96 is fixedly installed on the inner wall of the piston cavity 912, a piston plate 97 is slidably installed through and at the center of the fixed ring 96, a return spring 98 is fixedly connected to the side wall of the fixed ring 96, a ventilation cavity 99 is opened at the axis of the piston plate 97, an elastic connecting rod 910 is fixedly installed on the bottom surface of the piston plate 97, and a clamping block 911 is fixedly installed on the lower surface of the end of the elastic connecting rod 910 far away from the piston plate 97.

[0037] Meanwhile, the pinion gear 92 meshes with the large gear 93 to achieve transmission. A proximity switch is provided inside the rectangular groove. The proximity switch and the connecting block 94 are arranged in the same plane. So that during the process that the filter disc 81 is blocked and pushed upward along the inside of the rotating cylinder 4 by air pressure, the top of the connecting block 94 will contact the proximity switch. The proximity switch is electrically connected to the drive motor 91. Through a preset program, when the proximity switch is touched and triggered by the connecting block 94, the speed of the drive motor 91 is controlled to increase by one gear. When the connecting block 94 disengages from the proximity switch, the speed of the drive motor 91 is controlled to recover. Thus, when the filter disc 81 is blocked and affects the aeration volume of the aeration head 6, the rotation speed is increased to drive the aeration pipe 5 and the aeration head 6 to move in the waste gas treatment solution, so as to expand the diffusion range of the bubbles generated by aeration, enabling them to come into contact with the waste gas treatment solution more fully and complete the waste gas treatment work.

[0038] In an embodiment of the present invention, the piston plate 97 includes a circular piston member and a cylindrical member that are fixedly connected to each other. The cylindrical member penetrates and is movably connected to the center of the fixing ring 96. The return spring 98 is sleeved on the outer arc surface of the cylindrical member. The two ends of the return spring 98 are respectively fixedly connected to the side wall of the circular piston member and the side wall of the fixing ring 96. And in the initial state, due to the elastic force of the return spring 98, the piston plate 97 always has a tendency to move toward the side close to the rotating cylinder 4. Further, a latch adapted to the block 911 is provided on the bottom surface of the aeration pipe 5. And the end of the elastic connecting rod 910 away from the piston plate 97 is arranged directly above the dial block 95. Thus, during the process that the filter disc 81 is blocked and moves upward, through the drive of the connecting block 94 on the dial block 95, the top of the dial block 95 will squeeze the end of the elastic connecting rod 910 to release the limit of the block 911. At the same time, the speed of the drive motor 91 driving the pinion gear 92 to rotate increases. Under the action of centrifugal force, the piston plate 97 moves to the right along the inner surface of the center of the fixing ring 96 to squeeze the space of the piston chamber 912. Since this change is triggered by the upward movement of the filter disc 81 in the rotating cylinder 4, at this time, the filter disc 81 is blocked, resulting in a decrease in the air flow entering the aeration pipe 5. By pressurizing the air inlet area of the aeration head 6, that is, the piston chamber 912, the stable aeration of the aeration head 6 is ensured to guarantee the purification efficiency of the device for waste gas.

[0039] Please refer to the attached instructions Figures 6-7, in an embodiment of the present invention, a swinging assembly 10 is provided inside the aeration pipe 5 to increase the diffusion range of the bubbles generated by the lifting aeration head 6 in the treatment tank 1. The swinging assembly 10 includes a linkage ring 101, which is fixedly installed on the arc-shaped outer wall of the cylindrical part of the piston plate 97. A rack 102 is fixedly connected to the outer wall of the linkage ring 101 away from the piston plate 97. A transmission sleeve 103 is rotatably installed on the inner wall of the aeration pipe 5. The inner wall of the transmission sleeve 103 is rotatably connected to the aeration head 6. A scroll spring 104 is arranged inside the transmission sleeve 103. A vane 105 is fixedly installed on the arc-shaped outer wall of the aeration head 6.

[0040] Specifically, tooth patterns that mesh with the rack 102 and achieve transmission are provided on the top arc-shaped outer wall of the transmission sleeve 103, and the inside of the transmission sleeve 103 is hollow to facilitate the installation of the scroll spring 104. At the same time, both ends of the scroll spring 104 are fixedly connected to the top inner wall of the transmission sleeve 103 and the arc-shaped outer wall of the aeration head 6 respectively. Specifically, the aeration head 6 is rotatably connected to the inner wall of the aeration pipe 5. When the rotating cylinder 4 rotates inside the treatment tank 1 due to the drive of the drive motor 91, due to the blocking of the vane 105 by the waste gas treatment solution, the aeration head 6 has a tendency to rotate at the bottom of the aeration pipe 5. Due to the setting of the scroll spring 104, the aeration head 6 will also perform a reverse rotation movement during the rotation process, thereby further increasing the dispersion range of the small bubbles generated by the aeration head 6, making the waste gas more fully contact with the waste gas treatment solution, and thus improving the treatment effect of chemical waste gas. Further, when the piston plate 97 moves away from the rotating cylinder 4 due to centrifugal force after the pressurizing assembly 9 is triggered, the transmission sleeve 103 is driven by the rack 102, so that the transmission sleeve 103 deflects by a certain amplitude, thereby limiting the winding state of the scroll spring 104, and thus being able to change the maximum winding rotation range of the scroll spring 104, so that the bubble movement path generated when the aeration head 6 rotates and diffuses bubbles in the waste gas treatment solution is more random, increasing the diffusion range of the bubbles generated by the waste gas in the waste gas treatment solution, and ensuring the waste gas treatment efficiency of the device.

[0041] In the present invention, during use, the waste gas generated in the chemical reaction kettle is introduced into the fixed sleeve 2 and the rotating cylinder 4 through the air inlet pipe 3, and finally discharged into the waste gas treatment solution inside the treatment tank 1 through the air diffuser pipe 5 and the air diffuser head 6. The aerated waste gas moves upward after being absorbed by the waste gas treatment solution, and finally is discharged outward through the exhaust pipe 7. The end of the exhaust pipe 7 is connected to the chemical treatment equipment, so that the preliminarily treated waste gas enters the subsequent treatment process, reducing the environmental pollution caused by the emission of chemical waste gas. At the same time, by providing a puncture assembly 8, as the use time of the filter disc 81 increases, the bottom surface thereof will be blocked by solid impurities. Under the continuous input of waste gas, the air pressure inside the rotating cylinder 4 increases, so that the filter disc 81 moves upward along the inside of the rotating cylinder 4. Through the puncture of the filter core inside the filter disc 81 by the puncture needle 88, when encountering relatively stubborn solid impurities, the puncture needle 88 is blocked and moves upward. At this time, under the influence of the convex ball 85 and the spiral chute 86, the puncture needle 88 rotates self - sufficiently to improve the cleaning effect on the filter disc 81 and its internal filter element, ensure the air permeability of the filter disc 81, and further ensure the aeration treatment effect of the device on waste gas.

[0042] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
