[0013] This application provides a through-type chlorination reaction chamber, which solves the problems of existing chlorination reaction chambers, which are mostly intermittent and cannot meet the needs of large-scale continuous production. They also have technical problems such as uneven material flow leading to insufficient reaction, unstable product quality, poor sealing and fixing structure, and easy leakage and loosening of components.

[0014] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] A through-type chlorination reaction chamber, such as Figure 1 and Figure 2As shown, the system includes a mounting base 1, a mid-end fixing clip 21, a keyed fixing clip 22, a front-end fixing clip 23, a flow guide cap 3, a keyway cover plate 4, a graphite half-sleeve 5, a graphite bushing 6, a quartz reaction chamber 7, and an exhaust pipe connector 8. The mounting base 1 is a rectangular frame structure, connected to an external support structure by bolts, used to fix the reaction chamber. The mid-end fixing clip 21, the keyed fixing clip 22, and the front-end fixing clip 23 are respectively installed in the middle, keyway section, and front end of the quartz reaction chamber 7, achieving axial positioning through keyway fit and bolt fastening. The flow guide cap 3 is located at the end of the quartz reaction chamber 7 and is connected to the exhaust pipe connector 8. The inner cavity of the flow guide cap 3 is used to guide the chlorine gas to flow out. The keyway cover plate 4 covers the keyway area at the top of the quartz reaction chamber 7 and is fixed by a sealing gasket and screws. The graphite half-sleeve 5 and the graphite bushing 6 respectively cover part and the entire quartz reaction chamber 7 for corrosion resistance and uniform temperature distribution. The exhaust pipe connector 8 is connected to the guide cap 3 via a flange and is connected to the external exhaust pipe.

[0017] The bond width of the bond fixing clip 22 is adapted to the bond width of the quartz reaction chamber 7.

[0018] The flow guide cap 3 has a circular straight groove structure and is made of acid and alkali resistant, high temperature resistant engineering plastic.

[0019] The through-type chlorination reaction chamber also includes a retaining ring 9, which surrounds the graphite semi-shroud 5 and is located between the flow guide cap 3 and the keyway cover plate 4. The retaining ring 9 is used to secure the connections between components, ensuring the sealing of the reaction chamber and preventing leakage of gases such as chlorine by applying uniform pressure. The retaining ring 9 is typically made of high-strength, corrosion-resistant materials to withstand the special environment of the chlorination reaction. It surrounds the components that need to be connected and is secured by bolts or other fastening devices, ensuring the structural integrity of the entire reaction chamber.

[0020] In the assembly of the through-type chlorination reaction chamber in this embodiment, the graphite semi-sleeve 5 first partially wraps around the front end of the quartz reaction chamber 7, and the graphite bushing 6 completely wraps around the middle and rear sections of the quartz reaction chamber 7. The quartz reaction chamber 7 is then axially positioned and fixed using the middle fixing clip 21, the keyed fixing clip 22, and the front fixing clip 23. The flow guide cap 3 is installed at the end of the quartz reaction chamber 7 and connects to the exhaust pipe connector 8 to form a gas discharge channel. The keyway cover plate 4 seals the keyway area at the top of the quartz reaction chamber using a sealing gasket. During operation, materials are continuously input from one end of the reaction chamber, fully mixed with chlorine gas and reacted under the guidance of the flow guide cap 3, and the product is continuously discharged from the other end. During the reaction, the internal condition can be quickly checked through the keyway cover plate 4, and the graphite bushing 6 can be replaced simply by loosening the fixing clip bolts during periodic disassembly and maintenance.

[0021] Preparation before reaction:

[0022] The assembled reaction chamber undergoes an airtightness test by introducing inert gas at a certain pressure into the chamber and checking for leaks at each sealing point. According to the reaction process requirements, the reaction chamber is preheated or precooled to reach the appropriate reaction temperature. An external gas source is then turned on, and the valve at the gas pipe connector is adjusted to introduce chlorinating agent and other reaction gases at the set flow rate and pressure to purge the reaction chamber, removing internal air and impurities.

[0023] Chlorination reaction process:

[0024] The reactants are continuously and stably fed into one end of the reaction chamber via a feeding device. Guided by the flow guide cap 3, the materials are thoroughly mixed with the introduced chlorinating agent, and the chlorination reaction takes place within the quartz reaction chamber 7. During the reaction, parameters such as temperature, pressure, and material flow rate within the reaction chamber are monitored in real time, and the relevant parameters are adjusted through an automated control system to ensure that the reaction proceeds under the set process conditions. The tightness of all fixed components and the sealing performance of the sealing components are checked regularly, and any abnormalities are dealt with promptly.

[0025] Post-reaction processing:

[0026] The reaction products flow continuously from the other end of the reaction chamber, entering subsequent cleaning and purging processes. When it is necessary to stop the reaction, first stop the flow of reactants, then continue to flow a certain amount of chlorinating agent or inert gas to purge the reaction chamber and remove any residual chlorine gas. Turn off the external gas supply and allow the reaction chamber to cool to room temperature. Then, loosen the clamping rings, open the cover, and inspect and clean the inside of the reaction chamber. If any wear or damage is found in components such as the graphite bushing, replace them promptly.

[0027] Thanks to the inclusion of mounting base 1, mid-end fixing clip 21, keyed fixing clip 22, front-end fixing clip 23, flow guide cap 3, keyway cover plate 4, graphite half-bulb 5, graphite bushing 6, quartz reaction chamber 7, and exhaust pipe connector 8, this reaction chamber adopts a continuous design. Through the synergistic effect of the flow guide cap 3 and fixing clips 21-23, efficient material flow and complete reaction are achieved, significantly improving production efficiency. The multi-stage fixing clip structure, combined with the corrosion-resistant properties of the graphite bushing, ensures the sealing and stability of the reaction chamber during long-term operation, effectively preventing chlorine leakage. The design of the quartz reaction chamber 7 and graphite material not only ensures the equipment's lifespan in high-temperature and highly corrosive environments but also simplifies maintenance procedures and reduces production costs. Furthermore, the modular assembly method enhances the equipment's adaptability, flexibly addressing different process requirements. The through-flow design allows materials to continuously pass through the reaction chamber, achieving continuous chlorination production, significantly improving production efficiency, and meeting the needs of large-scale industrial production. The design of the flow guide cap 3 avoids the risk of environmental pollution caused by chlorine leakage, ensures workshop safety, makes the reaction more complete, and improves the yield and quality of the product.
