Description

Technical Field

[0001] This application relates to the field of chemical equipment technology, and in particular to a device for detecting gas leakage between sections of a multi-stage chlorination reactor. Background Technology

[0002] Chlorination reactors are important equipment for chlorination reactions. When using chlorination reactors, strict sealing and leakage detection measures should be ensured. Multi-stage chlorination reactors are usually composed of multiple reaction sections, with each reaction section connected to a vessel section. Due to aging, the gaskets between the vessel sections may cause the sealing measures to become less tight, resulting in a small amount of chlorine gas leaking from the reactor into the surrounding environment.

[0003] For multi-stage chlorination reactors, because the reactor sections are annular, the leakage point may be located far from the chlorine detection and alarm device. If the chlorine detection and alarm device cannot detect or detect the leakage in time, it will cause health hazards to the on-site operators. Utility Model Content

[0004] In order to detect leaks in the reactor in a timely manner, this application provides a multi-section chlorination reactor inter-section leakage detection device.

[0005] The multi-stage chlorination reactor inter-section leakage detection device provided in this application adopts the following technical solution:

[0006] A multi-stage chlorination reactor inter-section leakage detection device includes a multi-stage chlorination reactor composed of multiple reaction sections, with reactor sections between the multiple reaction sections. Each reactor section is fitted with a perforated duct. The perforated duct has evenly distributed air holes on one side close to the reactor section. One end of the perforated duct is connected to a tee connector and is connected to one branch pipe of the tee connector. The other end of the perforated duct is connected to the other branch pipe end of the tee connector. The main pipe of the tee connector is connected to a chlorine detection component.

[0007] By adopting the above technical solution, when chlorine leaks between vessel sections, the chlorine gas can enter the perforated duct along the vent near the vessel section. The leaking gas then travels along the duct to the tee joint and is conducted to the chlorine detection unit. The detection unit can then detect the leak. Even if a leak occurs far from the detection unit, the leaking gas can still enter the unit, ensuring timely detection.

[0008] Optionally, the chlorine detection assembly includes a chlorine detection box and a chlorine detection alarm. The main pipe of the three-way connector is connected to an air inlet pipe. The chlorine detection box has an air inlet, and an air inlet pipe connector is provided on the air inlet. The air inlet pipe connector is connected to the air inlet pipe, and the chlorine detection alarm is installed on the chlorine detection box.

[0009] By adopting the above technical solution, when chlorine is detected in the chlorine detection box, the chlorine detection alarm will sound an alarm in time, notifying relevant personnel to take timely measures to prevent the danger from escalating and thus contributing to safe production.

[0010] Optionally, one end of the chlorine detection chamber is connected to an oil-free piston vacuum pump, and the side of the oil-free piston vacuum pump away from the chlorine detection chamber is connected to a chlorine treatment device.

[0011] By adopting the above technical solution, the leaked chlorine gas is adsorbed by negative pressure using an oil-free piston vacuum pump, the gas leaking at the reactor section is extracted in real time, and the gas is sensed in time to prevent the disorderly spread of chlorine gas.

[0012] Optionally, an intake control valve is provided on the intake pipe, and an exhaust control valve is connected to the exhaust pipe.

[0013] By employing the above technical solution, the intake control valve controls the flow rate of fluid entering the system by opening or closing to a certain degree, while the exhaust control valve controls the flow rate of fluid leaving the system. Together, these two valves can precisely regulate the flow rate of fluid within the system to meet different operational requirements.

[0014] Optionally, a gasket is provided inside the reactor section, the gasket being close to the edges of two adjacent reaction sections, and the outer side of the gasket being flush with the outer edge of the reaction section.

[0015] By adopting the above technical solution, the gasket can help the two adjacent reaction sections of the reactor fit together better and seal better. By setting it flush, the gap between the perforated air duct and the reactor section is reduced, thus reducing the possibility of gas leakage.

[0016] Optionally, the reactor section is provided with a fixing assembly for fixing the perforated air duct. The fixing assembly includes a support platform, which is located below the perforated air duct and fixedly connected to the reaction section. The reaction section is located above the perforated air duct and is provided with a fixing ring. The fixing ring is provided with a plurality of fixing brackets, and the plurality of fixing brackets are fixedly connected to the fixing ring.

[0017] By adopting the above technical solution, the perforated duct can be fixed at the gap of the vessel section. The perforated duct is placed around the vessel section, and a support platform is used to hold the duct, preventing it from moving downwards due to gravity. To ensure a tighter fit between the perforated duct and the gap of the vessel section, a fixing ring and a fixing frame are used to fasten the duct, pressing it against the gap and reducing the possibility of chlorine leakage. This allows chlorine to enter the perforated duct and be detected promptly.

[0018] Optionally, the fixing frame is provided with a fastening plate, one end of which is rotatably connected to the fixing ring, and the fastening plate is connected to the support platform by bolts.

[0019] By adopting the above technical solution, after the fixing ring is fastened, the fastening plate is pulled to make the fastening plate fit against the inside of the fixing frame, and then fixed with bolts to completely fix the perforated air duct, preventing the untimely detection caused by the movement of the perforated air duct during use.

[0020] Optionally, a first sealing strip is provided at the reactor section and above the perforated air duct, and a second sealing strip is provided below the perforated air duct, with the first sealing strip and the second sealing strip surrounding the reaction section.

[0021] By adopting the above technical solution, the perforated air duct is in the shape of a round tube. When it is wrapped around the outside of the reactor section, there may be gaps between it and the two sides of the reactor side wall. By setting a sealing strip to seal the two sides of the perforated air duct, the situation of untimely detection due to air leakage is reduced.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By installing perforated ducts, air inlets, air ports, chlorine detection boxes, and chlorine detection alarms, even if a leak occurs in a part far from the chlorine detection components, the leaked gas can still enter the detection components, enabling timely detection of chlorine leaks. This allows for timely detection of gas leaks, prompting alarms and notifying relevant personnel to take timely measures to prevent the danger from escalating, thus promoting safe production.

[0024] 2. By setting up an oil-free piston vacuum pump, the gas leaking at the reactor section is extracted in real time, and the gas is detected in time to prevent the disorderly spread of chlorine gas;

[0025] 3. By setting up a support platform, fixing rings, and a fixing bracket, the perforated duct is prevented from moving downwards due to gravity. The engagement of the fixing rings and the fixing brackets holds the perforated duct against the gaps in the vessel section, reducing the possibility of chlorine leakage and allowing chlorine to enter the perforated duct for timely detection. The fastening plate fits snugly against the inside of the fixing bracket and is secured with bolts to prevent untimely detection due to movement of the perforated duct during use.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a device for detecting inter-section leakage in a multi-stage chlorination reactor. (Refer to...) Figure 1 and Figure 2 A multi-stage chlorination reactor inter-section leakage detection device includes a multi-stage chlorination reactor 1, which is composed of several reaction sections 101. A reactor section 102 is provided between two adjacent reaction sections 101, and multiple reactor sections 102 can be provided.

[0033] Reference Figure 1 and Figure 2 To prevent chlorine leakage from the multi-stage chlorination reactor 1, a gasket 2 is provided inside the reactor section 102. The gasket 2 is close to the edge of two adjacent reaction sections 101, and the outer side of the gasket 2 is flush with the outer edge of the reaction section 101.

[0034] Reference Figure 1 and Figure 3A fixing assembly is installed at reactor section 102. The fixing assembly includes a support platform 3 arranged around the lower of two adjacent reaction sections 101. A perforated air duct 4 is placed on the support platform 3 and is fitted over reactor section 102. The support platform 3 is used to support the perforated air duct 4 and prevent it from moving downward. The perforated air duct 4 has evenly spaced vents 5 on the side close to reactor section 102. The vents 5 are used to absorb leaked chlorine gas.

[0035] Reference Figure 2 and Figure 4 A fixing ring 6 is arranged around the upper reaction section 101 of two adjacent reaction sections 101. The fixing ring 6 is located above the perforated duct 4. Several fixing brackets 7 are evenly arranged around the circumference of the fixing ring 6 and are fixedly connected to the fixing ring 6. A fastening plate 8 is provided on the fixing bracket 7. One end of the fastening plate 8 is rotatably connected to the fixing ring 6, and the other end of the fastening plate 8 is connected to the support platform 3 by bolts. The side of the fastening plate 8 near the vessel section 102 abuts against the perforated duct 4 to reduce the gap between the perforated duct 4 and the vessel section 102 and reduce the possibility of leakage.

[0036] Reference Figure 2 A first sealing strip 9 is installed above the perforated duct 4, surrounding the upper reaction section 101 of two adjacent reaction sections 101. A second sealing strip 10 is installed below the perforated duct 4, surrounding the lower reaction section 101 of two adjacent reaction sections 101. The first sealing strip 9 and the second sealing strip 10 work together to seal the upper and lower sides of the perforated duct 4, reducing the possibility of delayed detection due to air leakage.

[0037] Reference Figure 1 and Figure 3 A perforated duct 4 is arranged around the perimeter with its two ends facing each other. One end of the perforated duct 4 is connected to a T-joint 11 and to one of the branch ends of the T-joint 11. The other end of the perforated duct 4 is connected to the other branch end of the T-joint 11. The main pipe of the T-joint 11 is connected to an air inlet pipe 12, which is equipped with an air inlet control valve 13. The other end of the air inlet pipe 12 is connected to a chlorine detection assembly. The chlorine detection assembly includes a chlorine detection box 14 and a chlorine detection alarm 16. The chlorine detection box 14 has an air inlet 15, which is equipped with an air inlet pipe 12 connector. The air inlet pipe 12 connector is connected to the air inlet pipe 12. The chlorine detection alarm 16 is installed on the chlorine detection box 14. When the chlorine detection box 14 detects chlorine, the chlorine detection alarm 16 issues a warning, prompting personnel to take protective measures.

[0038] Reference Figure 1The end of the chlorine detection chamber 14 furthest from the multi-stage chlorination reactor 1 is connected to an outlet pipe 18, which is equipped with an outlet control valve 19. The other end of the outlet pipe 18 is connected to an oil-free piston vacuum pump 20. The oil-free piston vacuum pump 20 applies negative pressure to accelerate the extraction of gas and promptly detects the gas, preventing the disorderly leakage of chlorine. The side of the oil-free piston vacuum pump 20 furthest from the chlorine detection chamber 14 is connected to a chlorine treatment device, which is an alkaline spray tower, used to wash and treat leaked chlorine.

[0039] The implementation principle of a multi-stage chlorination reactor 1 in this application embodiment is as follows: Under working conditions, when the gasket 2 corrodes and ages, there is a possibility of chlorine leakage. Once a chlorine leakage occurs at reactor section 102, the leaked chlorine gas enters the perforated duct 4 through the vent 5. Because the vent 5 is evenly distributed on the perforated duct 4, it can flow into the perforated duct 4 regardless of where the leakage occurs at reactor section 102. Furthermore, by setting an oil-free piston vacuum pump 20, a certain negative pressure is applied to the gas, allowing the gas to flow into the perforated duct 4 in a timely manner, preventing the possibility of leakage due to gas stagnation.

[0040] Gas flows into the inlet pipe 12 through the perforated duct 4 and the T-joint 11. The opening and closing of the inlet pipe 12 is controlled by the inlet control valve 13 to control the gas flow rate. Chlorine gas enters the chlorine detection box 14 through the inlet pipe 12. When a gas leak is detected, the chlorine detection alarm 16 will warn of the gas leak, and relevant personnel can then take appropriate measures. The leaked gas is connected to the alkali spray tower for treatment of the leaked chlorine.

[0041] The perforated duct 4 is wound around the vessel section 102. To prevent the perforated duct 4 from moving, it is held against the gap in the vessel section 102 by the support platform 3, the fixing ring 6, and the fixing frame 7, reducing the possibility of chlorine gas leakage and allowing chlorine gas to enter the perforated duct 4 in a timely manner for detection. The first sealing strip 9 and the second sealing strip 10 prevent gas from flowing out from the gaps on the upper and lower sides of the perforated duct 4, improving the safety of the equipment.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
