Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical exhaust gas treatment technology, specifically to a chemical production process exhaust gas treatment device. Background Technology
[0002] Chemical exhaust gas refers to the waste gas generated after chemical production. Chemical exhaust gas has a complex composition. For example, processes such as rebamipide synthesis, dibromobutenediol refining, acetoxyisobutyryl chloride preparation, anhydrous lithium bromide crystallization, monomethylamine methanol solution absorption, tetradecyltrimethylammonium bromide refining, and 2-hydroxyisobutyric acid catalytic synthesis generate large amounts of harmful gases during their production. These exhaust gases are mainly composed of organic VOCs, acidic gases, and alkaline gases. Direct discharge of these gases would negatively impact the ecological environment; therefore, a chemical exhaust gas treatment device is needed to treat them.
[0003] In the prior art, patent publication number CN202320794242.7 discloses a chemical tail gas treatment device, including a tower body. The left side wall of the tower body has a first opening, and the left side of the tower body has a gas guide pipe. The output end of the gas guide pipe passes through the first opening and extends into the interior of the tower body. A sedimentation tank is provided below the tower body. A maintenance plate is fixedly connected to the upper surface of the sedimentation tank by a nut. The upper surface of the maintenance plate has two second openings.
[0004] The above-mentioned exhaust gas treatment device has problems in actual use. For example, after the liquid participates in the reflux, it flows into the sedimentation tank, resulting in uneven distribution of the reaction solution. If the neutralized solution participates in the circulation operation again, the atomized solution cannot effectively participate in the exhaust gas atomization and purification operation and is discharged outside the device. Therefore, we propose an exhaust gas treatment device for chemical production processes. Utility Model Content

[0012] Furthermore, the treatment tower has a smoke inlet on the upper and lower sides of its outer arc surface, a smoke outlet pipe at the upper end of the treatment tower, and a liquid outlet pipe on the lower left side of its outer arc surface. The front end of the smoke inlet is connected to an external chemical exhaust device, the right end of the smoke outlet pipe is connected to a subsequent treatment device, and the left end of the liquid outlet pipe is connected to an external waste liquid collection device, thus realizing the functions of smoke inlet and smoke outlet.

This maintains the overall pH value of the solution at a threshold that effectively treats the exhaust gas, ensuring that each cycle of the solution effectively participates in the exhaust gas treatment operation. This allows for continuous and uninterrupted chemical exhaust gas treatment, preventing the problem of some chemical exhaust gas being discharged outside the equipment without treatment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This embodiment provides a technical solution: a chemical production process tail gas treatment device, including a treatment tower 1, characterized in that: it further includes an atomizing mechanism 5 and a rapid dissolution mechanism 6; a controller 10 is provided on the outside of the treatment tower 1, the input end of the controller 10 is electrically connected to an external power source; a smoke inlet 2 is provided on the lower side of the outer arc face of the treatment tower 1; a smoke outlet pipe 3 is provided at the upper end of the treatment tower 1; a liquid outlet pipe 4 is provided on the lower left side of the outer arc face of the treatment tower 1; the front end of the smoke inlet 2 is externally connected to external chemical exhaust equipment; the right end of the smoke outlet pipe 3 is externally connected to subsequent treatment equipment; the left end of the liquid outlet pipe 4 is externally connected to external waste liquid collection equipment; a liquid component detection module 7 is provided on the lower side of the outer arc face of the treatment tower 1; the measuring end of the controller 10 extends to the lower interior of the treatment tower 1; the liquid component detection module 7 is bidirectionally electrically connected to the controller 10; a demister 8 is provided on the upper interior of the treatment tower 1; the demister 8 is a wire mesh demister used in existing tail gas treatment tower technology; a viewing window 9 is provided on the upper front of the outer arc face of the treatment tower 1; the liquid component detection module 7... Customization is required based on work needs. For example, the waste gas generated during the preparation of dibromobutenediol and the waste gas from the synthesis of rebamipide are mainly composed of VOCs, various organic solvents, and organic by-products, supplemented by acidic gases HCl and SO2 and alkaline gases NH3 and organic amines. The waste gas from the preparation of acetoxyisobutyryl chloride is mainly composed of acidic gases HCl and SO2, volatile acyl chlorides, and VOCs. The waste gas from the anhydrous lithium bromide crystallization process is mainly composed of water vapor and hydrogen bromide HBr, possibly accompanied by a small amount of chlorine or organic waste gas. Most of the above production processes generate acidic and alkaline waste gas. Therefore, the mounting base of the liquid component detection module 7 integrates a pH sensor and an electronic water level gauge. Corresponding detection instruments can be added according to the type of industrial exhaust gas to be treated. The pH sensor and the electronic water level gauge are electrically connected to the controller 10 using methods commonly used in existing technologies. The pH sensor is an LTP200V model glass electrode pH sensor. The working principle of the pH sensor is to detect the pH through the glass electrode. + The selective response of H in the solution + Concentration is converted into a measurable potential difference. Combined with the Nernst equation and temperature compensation, the pH value is finally calculated and returned to the controller 10 as an electrical signal to realize real-time monitoring of the solution's pH information. The electronic water level gauge selected is the HSW-10 float-type electronic water level gauge. Its working principle is as follows: when the water level rises, the float rises with the water level, driving the internal potentiometer, encoder, or Hall sensor to rotate through the connecting rod or rope. The sensor converts the mechanical displacement into changes in resistance, voltage, or pulse signal. The circuit module amplifies and converts the electrical signal and returns the electrical signal to the controller 10 for display.
[0024] Atomizing mechanism 5: Located on the right side of processing tower 1, atomizing mechanism 5 includes a storage tank 51, a circulation pipe 52, an inlet pipe 53, a diversion pipe 54, atomizing nozzles 55, and a circulation pump 56. The storage tank 51 is located on the lower right side of processing tower 1. A circulation pipe 52 is located on the right side of the storage tank 51. Diversion pipes 54 are evenly distributed inside the upper part of processing tower 1. Atomizing nozzles 55 are evenly distributed on the lower outer arc surface of each of the two diversion pipes 54. The right ends of the two diversion pipes 54 are connected to the upper end of one circulation pipe 52. An inlet pipe 53 is located on the lower right side of the circulation pipe 52. The right end of the inlet pipe 53 is connected to an external liquid supply device. A circulation pump 56 is connected in series on the lower side of the circulation pipe 52. The input end of the circulation pump 56 is electrically connected to the output end of the controller 10. When using this exhaust gas treatment device, the exhaust gas can be analyzed. Taking the waste gas generated from the catalytic synthesis of 2-hydroxyisobutyric acid as an example, the main waste gas generated from the catalytic synthesis of 2-hydroxyisobutyric acid consists of carbon oxides CO2, CO, water vapor, and small molecule organic compounds such as aldehydes, ketones, and carboxylic acids. In this case, an alkaline solution such as NaOH or Na2CO3 is needed as the basic absorbent, combined with an oxidizing solution such as KMnO4 to treat this type of waste gas. After preliminary mixing, these solutions flow through an external liquid supply device to the inlet pipe 53, then through the circulation pipe 52, and finally into the diversion pipe 54. After atomization by the atomizing nozzle 55, water mist is continuously generated in the treatment tower 1. At this point, the controller 10 can be adjusted to operate the liquid component detection module 7, and the liquid... The pH monitoring instrument inside the component detection module 7 monitors the pH value of the liquid at the bottom of the treatment tower 1 in real time. The alkaline absorption tower needs to maintain the pH at 8-10 in real time. The water level detector inside the liquid component detection module 7 monitors the water level at the bottom of the treatment tower 1 in real time, keeping the water level above the storage tank 51. When the water level reaches the top of the storage tank 51, the external liquid supply equipment can be stopped and the operation can be stopped. The controller 10 will control the circulation pump 56 to operate. The circulation pump 56 will discharge the reaction solution at the bottom of the treatment tower 1 into the circulation pipe 52. The reaction solution will then pass through the inlet pipe 53 and the diversion pipe 54, and finally be atomized by the atomizing nozzle 55, continuously spraying mist water downwards. At this time, the external chemical exhaust equipment can be adjusted to discharge the exhaust gas into the treatment tower through the exhaust port 2. The waste gas enters the interior of treatment tower 1, and then the subsequent treatment equipment performs induced draft operation. At this time, the waste gas will flow from bottom to top in treatment tower 1. During the flow, the waste gas may contain acetic acid and unreacted hydroxyisobutyric acid, which come into full contact with the alkaline solution to undergo a neutralization reaction, forming salt and water. Finally, it flows to the lower interior of treatment tower 1. If the pH value is lower than 8, the external waste liquid collection equipment needs to be adjusted to suck out the waste liquid inside treatment tower 1, and the external liquid supply equipment will refill the alkaline solution inside treatment tower 1. During this period, the external chemical exhaust equipment will stop supplying smoke. After the neutralization reaction, the gas with mist rises at a certain speed. Due to the inertia of the rising mist, the mist collides with the fine wire mesh and adheres to the surface of the fine wire of demister 8.The diffusion of mist on the surface of the filaments and the gravitational settling of the mist cause the mist to form larger droplets. These droplets flow along the filaments of the demister 8 to the junction of the two filaments. The wettability of the filaments, the surface tension of the liquid, and the capillary action of the filaments cause the droplets to grow larger and larger. When the accumulated droplets become so large that their own weight exceeds the combined force of the gas's upward force and the liquid's surface tension, the droplets separate from the filaments of the demister 8 and fall to the bottom of the treatment tower 1. From there, they flow through the outlet pipe 4 to the external waste liquid collection equipment.
[0025] Rapid dissolving mechanism 6: It includes a cross-shaped sealing box 61, a rotating rod 62, a spiral stirring blade 63, and a sealed bearing 69. The sealed bearing 69 is a 6208CE type zirconia material corrosion-resistant, high-temperature waterproof bearing. The cross-shaped sealing box 61 is located inside the lower side of the processing tower 1. Sealed bearings 69 are respectively provided at the four corners of the lower side wall of the cross-shaped sealing box 61. A rotating rod 62 is fixedly connected to the inner ring surface of each sealed bearing 69. The upper end of each rotating rod 62 is rotatably connected to the upper side wall of one of the cross-shaped sealing boxes 61. Spiral stirring blades 63 are respectively provided on the lower side of the outer arc surface of the rotating rod 62. The four spiral stirring blades 63 are identical in shape. The rotation direction of two horizontally adjacent spiral stirring blades 63 is opposite to that of two vertically adjacent spiral stirring blades 63. The stirring blades 63 are formed by inverting two horizontally adjacent spiral stirring blades 63, so the four spiral stirring blades 63 have the same shape and rotate in opposite directions after being inverted. The rapid dissolving mechanism 6 also includes a multi-groove synchronous pulley 64, a transmission synchronous pulley 65, a synchronous belt 66, a motor 67, and a drive synchronous pulley 68. The multi-groove synchronous pulley 64 is rotatably connected to the middle of the upper and lower inner walls of the cross-shaped sealing box 61. The transmission synchronous pulleys 65 are fixedly sleeved on the upper side of the outer arc surface of the rotating rod 62. The four transmission synchronous pulleys 65 are all connected to one multi-groove synchronous pulley 64 through the synchronous belt 66. The motor 67 is located on the right side of the cross-shaped sealing box 61. The output shaft of the motor 67 is fixedly connected to the drive synchronous pulley 68, which is also connected to the synchronous belt 66. The multi-groove synchronous pulley 64 is connected to the drive synchronous pulley 65 (which is composed of five synchronous pulleys with their central axes overlapping; the synchronous pulleys in the multi-groove synchronous pulley 64 are connected to the drive synchronous pulley 65 and the driving synchronous pulley 68 on the same horizontal plane via a synchronous belt 66, and the upper end of the right-side rotating rod 62 is located in the middle of the synchronous belt 66 of the driving synchronous pulley 68). The input end of the motor 67 is electrically connected to the output end of the controller 10. When the liquid produced by the atomization and neutralization reaction and the liquid falling from the demister 8 fall to the bottom of the treatment tower 1, the controller 10 needs to be adjusted, the motor 67 will run, and the output shaft of the motor 67 will rotate, driving the driving synchronous pulley 68 to rotate, which in turn drives the multi-groove synchronous pulley 64 to rotate via the synchronous belt 66. The synchronous belt 66 drives four synchronous pulleys 65 to rotate synchronously, which in turn drives the spiral stirring blades 63 on the four rotating rods 62 to agitate the solution at the bottom of the treatment tower 1. This forces the spiral stirring blades 63 to agitate the solution, allowing the reacted solution to mix quickly with the unreacted solution. This prevents locally neutralized solution from re-entering the circulation process of the circulation pipe 52. If these neutralized solutions were to re-enter the circulation process and be atomized, they would not react with the gas. The rapid mixing of reacted and unreacted solutions ensures that the solution participating in each atomization process is involved in the neutralization reaction. The remaining gas is then discharged through the exhaust pipe 3 to the subsequent treatment equipment. At this point, the characteristics of the chemical exhaust gas need to be considered.If the exhaust gas contains a large amount of mixed waste gas of dust and VOCs, it is necessary to select activated carbon adsorption equipment or catalytic combustion equipment for fine treatment.
[0026] The working principle of the chemical production process tail gas treatment device provided by this utility model is as follows: When the tail gas treatment device is needed, the tail gas can be analyzed. Taking the waste gas generated by the catalytic synthesis of 2-hydroxyisobutyric acid as an example, the waste gas mainly generated by the catalytic synthesis of 2-hydroxyisobutyric acid mainly contains carbon oxides CO2, CO, water vapor, and small molecule organic compounds such as aldehydes, ketones, and carboxylic acids. At this time, an alkaline solution such as NaOH or Na2CO3 is needed as the basic absorbent, combined with an oxidizing solution such as KMnO4 to treat this type of waste gas. After preliminary mixing, these solutions can flow to the inlet pipe 53 through the external liquid supply equipment, then through the circulation pipe 52, and finally into the diversion pipe 54. Then, after atomization by the atomizing nozzle 55, the waste gas is treated in the treatment tower. Water mist is continuously generated within the treatment tower 1. At this time, the controller 10 can be adjusted to activate the liquid composition detection module 7. The pH monitoring instrument inside the liquid composition detection module 7 will monitor the pH value of the liquid at the bottom of the treatment tower 1 in real time. The alkaline absorption tower needs to monitor and maintain the pH at 8-10 in real time. The water level detector inside the liquid composition detection module 7 will monitor the water level at the bottom of the treatment tower 1 in real time, keeping the water level above the storage tank 51. When the water level reaches the top of the storage tank 51, the external liquid supply equipment can be stopped and the operation can be stopped. The controller 10 will then control the circulation pump 56 to operate. The circulation pump 56 will discharge the reaction solution at the bottom of the treatment tower 1 into the circulation pipe 52. The reaction solution will then pass through the inlet pipe 53 and the diversion pipe 54, and finally be atomized and sprayed. The first 55mm atomization continuously sprays water mist downwards. At this time, the external chemical exhaust equipment can be adjusted to discharge the waste gas into the interior of treatment tower 1 through inlet 2. Then, the subsequent treatment equipment performs induced draft operation, and the waste gas will flow from bottom to top in treatment tower 1. During the flow, the waste gas may contain acetic acid and unreacted hydroxyisobutyric acid, which come into full contact with the alkaline solution to undergo a neutralization reaction, forming salt and water. Finally, it flows to the lower interior of treatment tower 1. If the pH value is lower than 8, the external waste liquid collection equipment needs to be adjusted to suck out the waste liquid inside treatment tower 1, and the external liquid supply equipment refills the alkaline solution into treatment tower 1. During this period, the external chemical exhaust equipment will stop supplying smoke. After the neutralization reaction, the gas containing mist... The gas rises at a certain speed. Due to the inertia of the rising mist, the mist collides with the fine filaments of the demister 8 and adheres to the surface of the filaments. The diffusion of the mist on the filament surface and the gravitational settling of the mist cause the mist to form larger droplets that flow along the filaments of the demister 8 to the junction of the two filaments. The wettability of the filaments, the surface tension of the liquid, and the capillary action of the filaments cause the droplets to grow larger and larger until the accumulated droplets are large enough that their own weight exceeds the resultant force of the rising force of the gas and the surface tension of the liquid. At this point, the droplets separate from the filaments of the demister 8 and fall to the bottom of the treatment tower 1. When the liquid produced by the atomization and neutralization reaction and the liquid falling from the demister 8 fall to the bottom of the treatment tower 1, the controller 10 needs to be adjusted to activate the motor 67.The output shaft of motor 67 rotates, driving synchronous pulley 68 to rotate, which in turn drives multi-groove synchronous pulley 64 via synchronous belt 66. This, in turn, drives four transmission synchronous pulleys 65 to rotate synchronously, which in turn drives the spiral stirring blades 63 on the four rotating rods 62 to agitate the solution at the bottom of treatment tower 1. This ensures that the reacted solution quickly mixes with the unreacted solution, preventing partially neutralized solution from re-entering the circulation pipe 52. If these neutralized solutions were to re-enter the circulation and be atomized, they would not react with the gas. The rapid mixing of reacted and unreacted solutions ensures that each atomized solution participates in the neutralization reaction. The remaining gas is discharged through exhaust pipe 3 to subsequent treatment equipment. Depending on the characteristics of the chemical exhaust gas, if it contains a large amount of dust and VOCs, activated carbon adsorption or catalytic combustion equipment should be selected for further treatment.
[0027] It is worth noting that the core chip of the controller 10 disclosed in the above embodiments is a 51-type microcontroller. The circulating pump 56, motor 67, liquid composition detection module 7 and demister 8 can be freely configured according to the actual application scenario. It is recommended to use an IH80-50-200 type chemical circulating pump for the circulating pump 56, an MS112M-6-2.2KW type vertical motor for the motor 67, and the liquid composition detection module 7 can be selected according to the processing requirements. It is recommended to use a wire mesh demister 8. The controller 10 controls the operation of the circulating pump 56, motor 67 and liquid composition detection module 7 using methods commonly used in the prior art.
