The jacketed reaction vessel contains a chlorine injection module and a stirring module for agitating the solution. A fixed shell is fixedly connected inside the jacketed reaction vessel, with a through hole in its center. A water ring distributor is fixedly connected to the top of the jacketed reaction vessel.

Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, and in particular to a chlorination reaction vessel. Background Technology

[0002] As the core equipment in the chlorination process, the chlorination reactor is a precision pressure-resistant vessel that integrates mass transfer, heat transfer, and reaction. Its main body is usually made of special stainless steel or composite materials. It is equipped with a high-efficiency stirring system (such as turbine or propeller blades) and an external jacket or built-in coil heat exchange system to precisely control the temperature environment required for the strongly exothermic reaction. The chlorination reactor is a core piece of equipment in modern fine chemical, pesticide, pharmaceutical, and polymer material synthesis. It imparts key properties to products by introducing chlorine atoms into organic molecules.

[0003] However, the key component for chlorine injection in existing chlorination reactors—the gas distributor—is highly susceptible to corrosion at its nozzles under long-term exposure to high temperatures, wet chlorine, and hydrochloric acid. This corrosion can lead to enlarged nozzles, changes in shape, and localized perforations, causing chlorine gas to enter the solution as irregular, large bubbles. These large bubbles rise rapidly and are difficult to dissolve effectively, resulting in a large amount of chlorine escaping into the gas phase before reacting. This not only causes significant waste of raw materials, but also results in the direct loss of chlorine, an important reactant, without it participating in the reaction, significantly increasing production costs. Furthermore, it continuously impacts the downstream alkaline washing system. The high-concentration, fluctuating chlorine load can easily exceed the design capacity of the alkaline washing tower, causing the alkaline solution to quickly degrade. This not only increases operating costs but can also lead to the emission of toxic gases, causing environmental accidents and production interruptions. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides a chlorination reaction vessel.

[0005] The technical solution is as follows: a chlorination reactor includes a support frame, a jacketed reactor fixedly connected to the support frame, a liquid injection pipe fixedly connected and connected to the side wall of the jacketed reactor, a liquid outlet pipe and a vent pipe fixedly connected and connected to the bottom and top of the jacketed reactor respectively, a gas injection module for injecting chlorine gas is provided at the bottom of the jacketed reactor, a stirring module for stirring the solution is provided in the jacketed reactor, a fixed shell is fixedly connected inside the jacketed reactor, a through hole is provided in the middle of the fixed shell, the stirring module passes through the through hole of the fixed shell, a water ring distributor is fixedly connected to the top of the jacketed reactor, the projection of the through hole of the fixed shell on the horizontal plane is located within the projection of the water ring distributor on the horizontal plane, and a circulation component for extracting the solution inside the jacketed reactor is provided on the jacketed reactor.

[0006] As an improvement to the above solution, the circulation component includes a negative pressure pump, which is fixedly connected to the side wall of the jacketed reactor. The outlet end of the negative pressure pump is fixedly connected to the water ring distributor and connected to a first pipe. The first pipe passes through the jacketed reactor and is fixedly connected to each other. The inlet end of the negative pressure pump is fixedly connected to the jacketed reactor and connected to a second pipe.

[0007] As an improvement to the above solution, a liquid dispersion shell is fixedly connected to the lower side of the fixed shell. The liquid dispersion shell is frustum-shaped and has a through hole in the middle. The central axis of the liquid dispersion shell coincides with the central axis of the water ring distributor. The diameter of the through hole in the middle of the liquid dispersion shell is smaller than the diameter of the through hole in the middle of the fixed shell.

[0008] As an improvement to the above solution, a dividing cylinder is fixedly connected to the through hole in the middle of the liquid dispersion shell, and the dividing cylinder passes through the through hole in the middle of the fixed shell.

[0009] As an improvement to the above solution, the liquid-dispersing shell is slidably connected to a liquid-retaining ring, and a gap is left between the liquid-retaining ring and the inner wall of the jacketed reactor. The liquid-retaining ring is used to allow the solution on the liquid-dispersing shell to overflow onto the inner wall of the jacketed reactor.

[0010] As an improvement to the above solution, the jacketed reactor is fixedly connected to a driving component, and the jacketed reactor, the fixed shell, and the liquid distribution shell are jointly and slidably connected to a connecting frame. The telescopic end of the driving component is fixedly connected to the connecting frame, and the connecting frame is fixedly connected to the liquid baffle ring.

[0011] As an improvement to the above solution, the connection between the second pipe and the jacketed reactor is located between the fixed shell and the liquid distribution shell, and the second pipe passes through the liquid distribution shell.

[0012] As an improvement to the above solution, the second pipe is sealed and slidably connected to a sliding pipe, and the sliding pipe is fixedly connected to a float.

[0013] As an improvement to the above solution, the second pipe is slidably connected with a pressing block, which is used to press the sliding pipe to form a lock.

[0014] As an improvement to the above solution, the connecting frame is fixedly connected to a connecting ring inside the jacketed reactor, and the connecting ring is fixedly connected to a pressing block, which is used to press the pressing block.

[0015] The beneficial effects are: 1. This invention forms a dynamic water ring liquid seal on the chlorine discharge channel by cooperating with the fixed shell and the water ring distributor, thereby realizing the in-situ interception and secondary absorption of chlorine, significantly improving the utilization rate of chlorine, capturing the escaped chlorine and sending it back to the main reaction zone for continued reaction, while the water ring physically blocks the chlorine escape path, greatly reducing the instantaneous load and processing pressure of the downstream alkaline washing tower, and reducing the environmental risks caused by chlorine impact.

[0016] 2. The solution after absorbing chlorine is refluxed against the inner wall of the jacketed reactor by the liquid distribution shell, which prevents the solution from falling directly into the solution inside the jacketed reactor due to gravity and splashing. This reduces the probability of secondary desorption and volatilization of chlorine in the reflux solution. At the same time, the liquid baffle ring and the liquid distribution shell work together to evenly disperse the reflux solution in an overflow manner, so that the reflux solution adheres smoothly to the wall. Finally, the liquid baffle ring is controlled to reset so that the accumulated solution is discharged in an orderly and complete manner, reducing the probability of reflux solution remaining on the liquid distribution shell.

[0017] 3. By using a sliding tube and a float to extract the liquid surface solution from the jacketed reactor, the high-concentration bubble zone at the bottom is effectively avoided, significantly reducing the risk of undissolved chlorine gas being carried in the reflux liquid. This improves the chlorine absorption efficiency and reduces system disturbance. At the same time, the pressing block and the squeezing block work together to lock the sliding tube, ensuring that the height of the sliding tube extraction point is fixed and preventing the intake of gas phase due to liquid surface fluctuations or agitation. This ensures the stable operation of the water ring interception system and the reliability of the process. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] The core component used for chlorine injection in existing chlorination reactors—the gas distributor—is prone to enlargement, morphological distortion, and even localized perforation of its nozzles under long-term corrosion from high temperatures, wet chlorine, and hydrochloric acid. This results in chlorine entering the reaction liquid as irregular, large bubbles. Due to their rapid ascent, these bubbles are difficult to fully dissolve, and a large amount of chlorine escapes into the gas phase without participating in the reaction. This not only causes significant raw material waste and directly increases production costs but also subjects the downstream alkaline washing system to a continuous high-concentration, volatile chlorine load, easily exceeding its design capacity. This accelerates the consumption and deterioration of the alkali solution, increasing operating costs and potentially causing toxic gases to escape from the tail gas treatment system, leading to environmental accidents and unplanned shutdowns.

[0027] Example 1: This example provides a chlorination reactor to improve the utilization rate of chlorine gas.

[0028] like Figures 1-3As shown, the apparatus includes a support frame 1, which serves as the fixed base for the entire device. A jacketed reactor 2 is fixedly connected to the support frame 1. The jacket structure of the jacketed reactor 2 is used to introduce heating or cooling media, thereby controlling the temperature of the reaction system. This is to accommodate the characteristic that chlorination reactions are often strongly exothermic and require strict temperature control, ensuring that the reaction proceeds within the optimal temperature window. A liquid injection pipe 3 is fixedly connected and connected to the side wall of the jacketed reactor 2. The liquid injection pipe 3 is used to inject organic solution into the jacketed reactor 2. The bottom and top of the jacketed reactor 2 are respectively fixedly connected and connected... The reactor 2 is equipped with a liquid outlet pipe 4 and an exhaust pipe 5. The liquid outlet pipe 4 is used to discharge the material after the chlorination reaction is completed, and the exhaust pipe 5 is used to discharge the chlorine gas that enters the atmosphere of the jacketed reactor 2 during the reaction. The exhaust pipe 5 is usually directly connected to an external alkaline scrubbing tower for purifying harmful gases. A gas injection module 6 for injecting chlorine gas is installed at the bottom of the jacketed reactor 2. The gas injection module 6 is a gas distribution device, such as a bubble tube or a microporous sintering device, which disperses the introduced chlorine gas into bubbles as small as possible to increase the gas-liquid contact area and improve the dissolution and reaction rate of chlorine gas. The jacketed reactor 2 is equipped with a stirring module 7 for agitating the solution. The stirring module 7 consists of a servo motor and a rotating frame. The servo motor is fixedly connected to the top of the jacketed reactor 2, and the rotating frame is rotatably connected to the inside of the jacketed reactor 2. The output shaft of the servo motor is fixedly connected to the rotating frame to realize the rotation of the rotating frame. A fixed shell 8 is fixedly connected inside the jacketed reactor 2. The lower part of the fixed shell 8 is shaped like an inverted frustum, and a through hole is provided in the middle of the fixed shell 8. This through hole is the necessary path for the chlorine gas to rise. The rotating frame of the stirring module 7 passes through the fixed shell 8. A water ring distributor 9 is fixedly connected to the top of the jacketed reactor 2 through the through hole of the fixed shell 8. The water ring distributor 9 is located above the fixed shell 8 and is sealed to the top of the jacketed reactor 2, so that chlorine gas cannot bypass the water ring distributor 9. The water ring distributor 9 sprays an annular liquid curtain downward and falls onto the fixed shell 8, thereby forming a water ring that intercepts chlorine gas and improves the utilization rate of chlorine gas. The projection of the through hole of the fixed shell 8 on the horizontal plane is located within the projection of the water ring distributor 9 on the horizontal plane. The jacketed reactor 2 is equipped with a circulation component for extracting the solution inside itself.

[0029] like Figure 1 and Figure 2 As shown, the circulation assembly includes a negative pressure pump 201, which is fixedly connected to the side wall of the jacketed reactor 2. The outlet end of the negative pressure pump 201 is fixedly connected to the water ring distributor 9 and connected to a first pipe 202. The first pipe 202 passes through the jacketed reactor 2 and is fixedly connected to each other. The inlet end of the negative pressure pump 201 is fixedly connected to the jacketed reactor 2 and connected to a second pipe 203. In this embodiment, the connection point between the second pipe 203 and the jacketed reactor 2 is located below the surface of the organic solution in the jacketed reactor 2. The specific location can be freely set, but is limited to this embodiment.

[0030] Working principle: Before the chlorination reaction, the operator injects an organic solution into the jacketed reactor 2 through the injection pipe 3. After the solution injection is complete, the injection pipe 3 is closed (the injection height of the organic solution is below the injection pipe 3). Then, the stirring module 7 and the jacketed reactor 2 are turned on, causing the stirring module 7 to agitate the solution inside the jacketed reactor 2. Simultaneously, the jacketed reactor 2 heats the internal solution to a specific temperature. Then, chlorine gas is injected into the gas injection module 6. The chlorine gas enters the solution inside the jacketed reactor 2 evenly and dissolves in the solution. If the chlorine gas is not completely dissolved in the solution, it will enter the gas phase environment above the jacketed reactor 2. The chlorine gas rises through the through-hole in the middle of the fixed shell 8 and enters the alkali behind it through the exhaust pipe 5. The washing tower is used for purification. At the start of the chlorination reaction, the negative pressure pump 201 is turned on. The negative pressure pump 201 draws the solution in the jacketed reactor 2 and enters the water ring distributor 9 through the second pipe 203 and the first pipe 202. The water ring distributor 9 sprays the solution downward in the form of a water ring, so that the water ring sprayed downward by the water ring distributor 9 falls onto the fixed shell 8 and flows downward along the through hole in the middle back into the solution in the jacketed reactor 2. In this way, the path of chlorine gas entering the exhaust pipe 5 is completely blocked, so that the solution absorbs chlorine gas again and improves the utilization rate of chlorine gas. This cycle continues until the reaction is completed. Then, the stirring module 7, the jacketed reactor 2 and the negative pressure pump 201 are turned off, and the liquid outlet pipe 4 is turned on to drain the solution in the jacketed reactor 2. When chlorination is needed again, the above steps are repeated.

[0031] Example 2: This example provides a chlorination reactor, which is a further improvement on Example 1.

[0032] like Figures 3-5As shown, a liquid distribution shell 301 is fixedly connected to the lower side of the fixed shell 8. The liquid distribution shell 301 is frustoconical in shape, with a through hole in the middle. The central axis of the liquid distribution shell 301 coincides with the central axis of the water ring distributor 9. The diameter of the through hole in the middle of the liquid distribution shell 301 is smaller than the diameter of the through hole in the middle of the fixed shell 8. As a receiver and initial distributor of reflux solution, its frustoconical shape can smoothly guide the falling solution to the surrounding area, creating conditions for subsequent uniform overflow. The diameter of the through hole in the middle is smaller than the diameter of the through hole in the fixed shell 8. A dividing cylinder 302 is fixedly connected to the through hole in the middle of the liquid distribution shell 301. The dividing cylinder 302 passes through the through hole in the middle of the fixed shell 8. The top of the dividing cylinder 302 is higher than the bottom of the fixed shell 8 to prevent the reflux solution on the fixed shell 8 from entering the dividing cylinder 302, ensuring that the reflux solution is fully intercepted and dispersed. A liquid-blocking ring 303 is slidably connected to the liquid distribution shell 301. There is a gap between the liquid-blocking ring 303 and the inner wall of the jacketed reactor 2. The liquid-retaining ring 303 has a gap and is used to allow the solution on the liquid-dispersing shell 301 to overflow onto the inner wall of the jacketed reactor 2. In the initial state, the top of the liquid-retaining ring 303 is in contact with the outer edge of the liquid-dispersing shell 301. The liquid-retaining ring 303 is used to block the backflow solution on the liquid-dispersing shell 301, thereby forming a liquid storage area. The solution is forced to overflow evenly after reaching a certain liquid level. The top of the jacketed reactor 2 is fixedly connected to a driving component 304, which is an electric push rod. The jacketed reactor 2, the fixed shell 8, and the liquid-dispersing shell 301 are jointly and slidably connected to a connecting frame 305. The telescopic end of the driving component 304 is fixedly connected to the connecting frame 305. The connecting frame 305 is fixedly connected to the liquid-retaining ring 303. The telescopic end of the driving component 304 can drive the liquid-retaining ring 303 to move up and down through the connecting frame 305. After the chlorination reaction is completed, the driving component 304 can control the liquid-retaining ring 303 to descend, thereby completely draining the residual backflow solution on the liquid-dispersing shell 301.

[0033] Working principle: At the start of the above chlorination reaction process, the drive unit 304 is activated. The telescopic end of the drive unit 304 drives the connecting frame 305 to move upward. The connecting frame 305 drives the liquid-retaining ring 303 to move upward synchronously. This continues until the bottom of the liquid-retaining ring 303 is flush with the bottom of the liquid distribution shell 301. Then, the drive unit 304 is closed. The solution left in the through hole in the middle of the fixed shell 8 is blocked by the dividing cylinder 302 and falls onto the liquid distribution shell 301. It then disperses and flows downward along the liquid distribution shell 301. Due to the obstruction of the liquid-retaining ring 303, the initial solution cannot flow downward along the inner wall of the jacketed reactor 2 and accumulates between the liquid distribution shell 301 and the liquid-retaining ring 303. This continues until the liquid level between the two is equal to the liquid distribution shell 301. After the top of the baffle ring 303 is aligned with the liquid-retaining ring, the solution begins to overflow downwards around the baffle ring 303. The overflowing solution flows downwards along the inner wall of the jacketed reactor 2 and eventually converges into the solution at the bottom of the jacketed reactor 2. This continues until the reaction is complete. Then, the drive unit 304 is activated again. The telescopic end of the drive unit 304 drives the connecting frame 305 to reset downwards. At this time, the connecting frame 305 drives the baffle ring 303 to gradually reset downwards, so that the baffle ring 303 is reset to its initial state. During this period, the solution between the liquid distribution shell 301 and the baffle ring 303 gradually overflows downwards as the height of the baffle ring 303 decreases and flows back into the solution inside the jacketed reactor 2 along the inner wall. When a chlorination reaction is required again, the above steps are repeated.

[0034] Example 3: This example provides a chlorination reactor, which is a further improvement on Example 2.

[0035] like Figure 5 and Figure 6 As shown, the second pipe 203 is sealed and slidably connected to a sliding tube 401. The sliding tube 401 can slide up and down along the second pipe 203. A float 402 is fixedly connected to the bottom of the sliding tube 401. The float 402 is used to keep the sliding tube 401 suspended below the solution surface of the jacketed reactor 2, i.e., at the surface level, thereby avoiding the high bubble area at the bottom of the jacketed reactor 2. The connection between the second pipe 203 and the jacketed reactor 2 is located between the fixed shell 8 and the liquid distribution shell 301 to ensure the flow of the reflux solution on the inner wall of the jacketed reactor 2 below the liquid distribution shell 301. Regarding stability, the second pipe 203 penetrates the liquid distribution shell 301. A pressing block 403 is slidably connected to the second pipe 203 below the liquid distribution shell 301. The pressing block 403 is used to squeeze the sliding pipe 401 to form a lock. A connecting ring 404 is fixedly connected to the connecting frame 305 inside the jacketed reactor 2. The connecting ring 404 is located below the liquid distribution shell 301. A squeezing block 405 is fixedly connected to the connecting ring 404. The squeezing block 405 is a right-angled trapezoidal block with its lower base located at the bottom. The inclined waist of the squeezing block 405 fits against the pressing block 403. The squeezing block 405 is used to squeeze the pressing block 403.

[0036] Working principle: When the solution is injected into the jacketed reactor 2, as the solution level rises continuously within the jacketed reactor 2, the solution level causes the float 402 to move upward, which in turn causes the sliding tube 401 to slide upward along the second pipe 203. This continues until the solution injection is completed. At this point, the sliding tube 401 draws back the solution at the solution level in the jacketed reactor 2. The solution at the solution level has a low chlorine gas bubble content, reducing the probability of the solution carrying chlorine gas bubbles back. Then, when the telescopic end of the drive component 304 drives the connecting frame 305 to move upward, the connecting frame 305 drives the connecting ring 404 to move synchronously, causing the connecting ring 404 to drive the pressing block 405 on it to move synchronously. The pressing block 405 presses the pressing block 403, which in turn presses the sliding tube 401, thus forming a compression lock on the sliding tube 401. Then, the chlorination reaction begins, and this continues until the reaction is completed.

[0037] After the chlorination reaction is completed, the telescopic end of the drive component 304 drives the connecting ring 404 to reset via the connecting frame 305. The connecting ring 404 drives the pressing block 405 on it to move downward synchronously, so that the pressing block 405 releases the pressure on the pressing block 403, and the pressing block 403 releases the pressure on the sliding tube 401. Then, as the solution in the jacketed reactor 2 is discharged, the sliding tube 401 moves downward along the second pipe 203 to the initial position. When the chlorination reaction needs to be carried out again, the above steps are repeated.

[0038] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
