Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to an explosion-proof structure for a chemical reaction vessel. Background Technology
[0002] Chemical reaction vessels are an indispensable core piece of equipment in chemical production and are widely used in various chemical reaction processes. However, due to the complex conditions such as high temperature, high pressure, and corrosive media often present during chemical reactions, reaction vessels are prone to explosion accidents caused by excessive pressure or abnormal temperature, resulting in serious safety hazards and economic losses.
[0003] Existing explosion-proof structures mostly use a single pressure relief device or pressure sensor, which is difficult to comprehensively cope with complex reaction conditions. In addition, they are complex in structure and have high maintenance costs. A single pressure or temperature monitoring device will have a delayed response in abnormal conditions and will not be able to take timely measures to prevent accidents. Therefore, there is an urgent need for a simple and highly reliable explosion-proof structure for chemical reactors to improve the safety and stability of the equipment.
[0004] Based on this, an explosion-proof structure for chemical reaction vessels is now provided, which can eliminate the drawbacks of existing equipment. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] In one embodiment, such as Figures 1-4 As shown, an explosion-proof structure for a chemical reactor includes a pressure relief assembly, which is disposed on one side of the chemical reactor 1, and a detection assembly is disposed on the other side of the chemical reactor 1.
[0026] The pressure relief assembly includes a pressure relief pipe 12, the lower end of which is inserted through the interior of the chemical reactor 1 and equipped with a solenoid valve. The upper end of the pressure relief pipe 12 is fixedly connected to a pressure relief valve 13. The output end of the pressure relief valve 13 is fixedly connected to an exhaust pipe 14. The upper end of the exhaust pipe 14 is fixedly connected to a filter box 15. The upper end of the filter box 15 has an air outlet 16.
[0027] In this embodiment, when the pressure or temperature exceeds the set value, the control system activates the pressure relief component, the solenoid valve opens, and the overpressure gas is discharged through the pressure relief pipe 12 and the pressure relief valve 13. After being filtered by the filter box 15, it is discharged from the outlet 16.
[0028] In one embodiment, such as Figure 4 As shown, the pressure relief valve 13 is a spring-loaded pressure relief valve, which enables active pressure relief.
[0029] In one embodiment, such as Figure 1 As shown, the detection assembly includes a detection seat 5, one end of which is inserted into the interior of the chemical reactor 1, and a plurality of detection sensors 6 are provided at the end located inside the chemical reactor 1. The explosion-proof pressure sensor and temperature sensor in the detection assembly monitor the pressure and temperature inside the reactor in real time and transmit the data to the control system.
[0030] In one embodiment, such as Figure 1 As shown, the detection sensors 6 are an explosion-proof pressure sensor and an explosion-proof temperature sensor, which monitor the pressure and temperature inside the reactor, respectively.
[0031] In one embodiment, such as Figure 2 As shown, a cooling component is provided on the outer side of the lower end of the chemical reactor 1 to cool the interior of the chemical reactor 1.
[0032] In one embodiment, such as Figure 2 As shown, the cooling assembly includes a cooling machine 4, which comprises a compressor, a condenser, an evaporator, an expansion valve, and refrigerant pipes. The compressor compresses the refrigerant, changing it from a low-temperature, low-pressure gas to a high-temperature, high-pressure gas, driving a refrigeration cycle. The condenser cools and condenses the high-temperature, high-pressure refrigerant gas into a liquid, releasing heat to the outside. The expansion valve controls the flow and pressure of the refrigerant, changing it from a high-pressure liquid to a low-pressure liquid, which then enters the evaporator. The refrigerant evaporates in the evaporator, absorbing indoor heat and achieving cooling. A support base 8 is fixedly connected to the lower end of the cooling machine 4, and a cooling jacket 7 is fixedly connected to the upper end of the cooling machine 4. The cooling jacket 7 is located on the outer side of the lower end of the chemical reactor 1. A threaded pipe is installed inside the cooling jacket 7 and is fixedly connected to the output end of the cooling machine 4. When the temperature is too high, the cooling assembly starts, and the cooling machine 4 circulates the refrigerant through the threaded pipe inside the cooling jacket 7, quickly reducing the temperature of the reactor.
[0033] In one embodiment, such as Figure 3 As shown, a valve cover assembly is provided above the chemical reactor 1. The valve cover assembly includes a reactor cover 10. A safety rupture disc 11 is provided on one side of the upper surface of the reactor cover 10. A flange 9 is fixedly connected to the connection between the reactor cover 10 and the chemical reactor 1. If the pressure relief assembly fails, the safety rupture disc 11 will rupture, releasing overpressure gas and preventing the reactor from exploding.
[0034] In one embodiment, such as Figure 1 As shown, a fixed frame 2 is fixedly connected to the outside of the chemical reaction vessel 1. Several support legs 3 are fixedly connected around the lower surface of the fixed frame 2. The fixed frame 2 and the support legs 3 ensure that the reaction vessel remains stable during operation and avoid accidents caused by vibration or tilting.
[0035] The above embodiment discloses an explosion-proof structure for a chemical reactor. The explosion-proof pressure sensor and temperature sensor in the detection component monitor the pressure and temperature inside the reactor in real time and transmit the data to the control system. When the pressure or temperature exceeds the set value, the control system activates the pressure relief component, the solenoid valve opens, and the overpressure gas is discharged through the pressure relief pipe 12 and pressure relief valve 13. After being filtered by the filter box 15, it is discharged from the outlet 16. When the temperature is too high, the cooling component is activated, and the cooling machine 4 circulates refrigerant through the threaded pipe in the cooling jacket 7 to quickly reduce the temperature of the reactor. If the pressure relief component fails, the safety rupture disc 11 ruptures, releasing the overpressure gas and preventing the reactor from exploding. The fixing frame 2 and support legs 3 ensure the reactor remains stable during operation, avoiding accidents caused by vibration or tilting.
[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
