In the process of equipment operation, high temperature, high pressure, corrosive or flammable and explosive substances may be generated in the internal due to material reaction, decomposition or accumulation. Once the temperature in the equipment is too high or the condition is out of control, leakage, explosion and other serious accidents will be caused, which will threaten the safety of personnel and the stability of production.

The structure reinforcement increases the strength and pressure resistance of the closed equipment, but cannot avoid the occurrence of explosion, and the pressure at the time of explosion is higher and the danger is higher. Pressure monitoring and external relief are generally used simultaneously. When the pressure rises above the threshold, the pressure is relieved from the outside to reduce the pressure in the closed equipment.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] Reference Figures 1 to 5 As shown in the figure, the present embodiment provides an explosion suppression and pressure relief control device for accidental explosion during the operation stage of a sealed device, which comprises an inhibitor spraying assembly in communication with the sealed device, and the inhibitor spraying assembly is used to spray the inhibitor to the sealed device when the explosion occurs in the sealed device.

[0030] The side wall of the sealed device is provided with a multi-layer rapid pressure relief assembly 2, and the multi-layer rapid pressure relief assembly 2 is automatically destroyed when the explosion occurs in the sealed device, so as to make the inner cavity of the sealed device communicate with the outside and relieve the pressure in the inner cavity of the sealed device.

[0031] The multi-layer rapid pressure relief assembly 2 comprises a rapid impact module 8 embedded and installed in the side wall of the sealed device, and the rapid impact module 8 is started when the explosion occurs in the inner cavity of the sealed device, so as to pierce the inner side pressure-resistant material 9 attached to the inner wall of the sealed device and relieve the pressure in the inner cavity of the sealed device.

[0032] The application discloses a closed device operation stage accidental explosion suppression and pressure relief control device, which is composed of a multilayer rapid pressure relief assembly 2 arranged on a closed device and a suppressant spraying assembly in communication with the closed device, and forms a complete system of "detection-explosion suppression-pressure relief" coordinated linkage. When the device explodes, the suppressant spraying assembly sprays suppressant into the device cavity accurately, directly acts on the surface of the reaction object of the explosion source, directly acts on the explosion reaction system by spraying the suppressant, can quickly suppress the high temperature and flame generated by the explosion, blocks the development of the explosion from the chemical suppression level, solves the problem that the traditional technology lacks active inhibition ability when the explosion occurs, and restrains the expansion of the explosion from the source. The multilayer rapid pressure relief assembly 2 is installed on the side wall of the closed device and belongs to a passive trigger type pressure relief structure, can be automatically damaged under abnormal working conditions of the device explosion, realizes rapid communication between the device cavity and the outside world, rapidly releases the high pressure generated in the cavity due to the explosion, and avoids continuous pressure accumulation. During the treatment process, the suppressant spraying and the multilayer rapid pressure relief action are synchronous and linked, the pressure relief creates a stable pressure environment for smooth and safe spraying of the suppressant, avoids hindering the diffusion of the suppressant due to high pressure, the explosion suppression blocks the development of the explosion at the same time of the pressure relief, the two form a complement, solves the bottleneck of the traditional technology that the response is lagging, the release efficiency is low, and the accident expansion is difficult to suppress, and provides more comprehensive and accurate safety protection for the closed device operation stage. The rapid impact module 8 is the core execution unit of the multilayer rapid pressure relief assembly 2 and is embedded and installed on the side wall of the closed device; when the device cavity explodes, the module starts immediately, penetrates the inner pressure-resistant material 9 adhered to the inner wall of the device through mechanical impact, quickly opens the pressure relief channel, realizes instantaneous communication between the cavity and the outside world, can rapidly release the high pressure generated by the explosion, at the same time, offsets the pressure superposition in the suppressant spraying process, effectively prevents the closed device from being broken due to pressure surge, and guarantees the safety of the device structure. The application has strong adaptability, does not need additional complex operation through the embedded installation and automatic triggering mode, at the same time of quickly disposing the explosion accident, maximally reduces the interference on the normal operation logic of the device, and takes into account safety and practicability.

[0033] Further optimization scheme, the rapid impact module 8 includes a slidable sharp hammer body 12, the tip of the sharp hammer body 12 is towards the inner side pressure-resistant material 9, the side of the sharp hammer body 12 away from the inner side pressure-resistant material 9 is abutted and fitted with a gas generating agent 10, when the sealed equipment occurs combustion and explosion, the gas generating agent 10 generates gas to push the sharp hammer body 12 to slide, and crushes the inner side pressure-resistant material 9. When combustion and explosion occur, the gas generating agent 10 reacts in milliseconds to generate a large amount of gas, which increases the pressure on the side of the sharp hammer body 12 away from the tip, pushes the sharp hammer body 12 to rapidly impact the inner side pressure-resistant material 9, crushes the inner side pressure-resistant material 9, and connects the inside and outside of the sealed equipment, realizes rapid pressure relief in the sealed equipment, solves the problem of response lag of mechanical driving, ensures that the pressure relief action is synchronized with the occurrence of combustion and explosion; the tip of the sharp hammer body 12 is towards the inner side pressure-resistant material 9, the impact force is concentrated, which can efficiently penetrate the inner side pressure-resistant material 9, and avoid the problem that the pressure relief channel cannot be quickly opened due to insufficient impact force; the whole device has simple and reliable power structure, does not need complex transmission components, reduces the risk of failure, and meets the emergency response demand in the combustion and explosion scene.

[0034] In an embodiment of the present application, the gas generated by the gas generating agent 10 is non-combustible and non-polluting, which can avoid the risk of ignition of the generated gas by high temperature, and improve safety.

[0035] Further optimization scheme, the side wall of the sealed equipment is embedded and installed with a hammer body running cylinder 13, the sharp hammer body 12 is slidingly connected in the hammer body running cylinder 13, the inner side pressure-resistant material 9 is in abutment with the inner end of the hammer body running cylinder 13, and the gas generating agent 10 is in abutment with the outer end of the hammer body running cylinder 13. The hammer body running cylinder 13 is a tubular structure, which is embedded in the side wall of the sealed equipment, does not damage the structural integrity of the main body of the sealed equipment, integrates the original sealing performance and protection function of the equipment, realizes the positioning and fixing of the gas generating agent 10 and the inner side pressure-resistant material 9, guarantees the stability of the power transmission path, and avoids the influence of displacement of components on the pressure relief efficiency; the hammer body running cylinder 13 provides precise sliding guidance for the sharp hammer body 12, avoids the deviation of the hammer body during the impact process, ensures that the tip accurately acts on the inner side pressure-resistant material 9, and improves the penetration success rate; meanwhile, the gas generating agent 10 is arranged on the side of the hammer body running cylinder 13 away from the tip of the sharp hammer body 12, so that the gas generated by the gas generating agent 10 enters the hammer body running cylinder 13, the pressure on the back side of the sharp hammer body 12 rapidly increases, and the leakage of the gas generated by the gas generating agent 10 is effectively avoided.

[0036] In a further optimized design, a flexible sealing ring 11 is fitted onto the outer wall of the pointed hammer body 12, with the outer ring of the sealing ring 11 abutting against the inner wall of the hammer body running cylinder 13. The sealing ring 11 achieves gap sealing between the pointed hammer body 12 and the hammer body running cylinder 13, preventing leakage of flammable and explosive substances, corrosive gases, or inhibitors inside the equipment, and ensuring the sealing performance during normal operation of the equipment. At the same time, the sealing ring 11 also ensures cavity sealing between the pointed hammer body 12 and the gas-generating agent 10, ensuring that the gas generated by the gas-generating agent 10 accumulates in the cavity and does not leak, thereby increasing the pushing pressure on the back of the pointed hammer body 12.

[0037] To further optimize the design, several vent holes 14 are provided through the inner sidewall of the hammer running cylinder 13. These vent holes 14 are connected to the outside of the sealed equipment. After the inner pressure-resistant material 9 is broken by the pointed hammer 12, the pressure inside the sealed equipment is released through the vent holes 14. The vent holes 14, located on the sidewall of the hammer running cylinder 13, form a high-pressure gas release channel. When the inner pressure-resistant material 9 is broken, the high-pressure gas generated by the combustion and explosion in the sealed equipment enters the hammer running cylinder 13 and is then released through the vent holes 14, preventing the sealing effect of the sealing ring 11 from affecting the release effect.

[0038] In one embodiment of the present invention, the tip of the pointed hammer 12 can also increase the space between the exhaust hole 14 and the pointed hammer 12 after breaking the inner pressure-resistant material 9, thereby improving the release efficiency of high-pressure gas, realizing rapid depressurization of the sealed equipment, and reducing the risk of damage to the sealed equipment.

[0039] The design is further optimized by installing a porous flame-retardant material 7 on the outer wall of the sealed equipment. This material 7 is positioned correspondingly to the hammer running cylinder 13, pressing the gas-generating propellant 10 against the outer end of the hammer running cylinder 13. The porous flame-retardant material 7, installed on the outer wall of the sealed equipment, reliably fixes the gas-generating propellant 10, preventing displacement due to equipment transport or operational vibrations and ensuring stable power output. Simultaneously, the porous flame-retardant material 7 possesses flame-retardant and heat-insulating properties, preventing internal combustion flames or high temperatures from being conducted to the gas-generating propellant 10, thus preventing accidental triggering and improving device safety. Furthermore, it effectively prevents flames and high temperatures within the pressure-bearing body 1 from leaking into the outside environment through the open hammer running cylinder 13, reducing the impact on the external environment and improving the safety of the automatic pressure relief process. The porous structure does not affect the gas discharge during combustion of the gas-generating propellant 10, ensuring unimpeded thrust output and balancing fixed protection with power transmission efficiency.

[0040] In one embodiment of the present invention, the porous flame-retardant material 7 has porous properties, which can form a dense physical barrier to block the flame propagation path and isolate oxygen from contact with combustibles. On the other hand, it can absorb some of the heat generated by the flame combustion, reduce the local temperature, and slow down the combustion reaction.

[0041] In one embodiment of the present invention, the porous fire-retardant material 7 is a high-efficiency composite porous fire-retardant material composed of inorganic salts such as sodium bicarbonate (NaHCO3), potassium bicarbonate (KHCO3), sodium carbonate (Na2CO3), and potassium carbonate (K2CO3). Under high-temperature conditions, it will trigger a series of chemical changes, inhibit the combustion reaction from the source, and at the same time help to enhance the fire-retardant effect.

[0042] The design is further optimized. The sealed equipment includes a pressure-bearing body 1 connected to the inhibitor spraying assembly. The hammer operating cylinder 13 is embedded in the side wall of the pressure-bearing body 1. Porous fire-retardant material 7 is attached to the outer wall of the pressure-bearing body 1, and inner pressure-resistant material 9 is attached to the inner wall of the pressure-bearing body 1. All core components are integrated with the pressure-bearing body 1, without occupying additional external space, and adapting to the compact layout requirements of the sealed equipment. The inner pressure-resistant material 9 attached to the inner wall and the porous fire-retardant material 7 attached to the outer wall respectively ensure the sealing and external protection of the equipment during normal operation without affecting the original function of the equipment. The integrated installation method improves the reliability of component connections, avoids response failure in emergency situations due to loose installation, enhances the overall stability of the device, and ensures the safety of the device.

[0043] The scheme has been further optimized by installing a detection sensor 4 inside the pressure-bearing body 1. When a combustion or explosion occurs inside the pressure-bearing body 1, the detection sensor 4 controls the activation of the inhibitor spraying assembly to spray inhibitor into the pressure-bearing body 1. The detection sensor 4 sends a control signal to trigger the inhibitor spraying assembly to activate and spray inhibitor into the body, achieving automatic linkage between detection and explosion suppression without manual intervention. This solves the response delay problem caused by manual operation in traditional technologies. The detection sensor 4 accurately identifies combustion and explosion signals, ensuring that the inhibitor spraying assembly only activates in emergency situations, avoiding material waste and equipment contamination caused by accidental triggering. Simultaneously, the detection sensor 4 is synchronized with the pressure relief action, forming a closed-loop control of "detection-explosion suppression-pressure relief," further improving the coordination and efficiency of accident response.

[0044] The scheme has been further optimized. The inhibitor spraying assembly includes an inhibitor storage tank 6, which is connected to a nozzle 3 mounted on the pressure-bearing body 1. An inhibitor delivery pipeline 5 is installed between the inhibitor storage tank 6 and the nozzle 3. The inhibitor storage tank 6 enables centralized storage of the inhibitor material, ensuring sufficient supply during combustion and explosion and preventing explosion suppression failure due to insufficient material. The nozzle 3 is directly mounted on the pressure-bearing body 1 and connected to the inhibitor storage tank 6 via the inhibitor delivery pipeline 5, shortening the inhibitor spraying path and ensuring rapid coverage of the combustion and explosion area by the inhibitor material, thereby improving the explosion suppression effect. The assembly has a simple structure, is easy to maintain and replenish inhibitors, and reduces equipment operating costs.

[0045] Specific example 1:

[0046] See attached document Figure 4 As shown, when the pressure-bearing body 1 is an oven, if an accidental explosion occurs during the drying process, the detection sensor 4 selects a flame sensor and places it inside the oven to detect the accidental explosion flame during the drying process. A nozzle 3 is built into the top of the oven, and the nozzle 3 is connected to the inhibitor storage tank 6 via an inhibitor delivery pipeline 5. A multi-layer rapid pressure relief assembly 2 is installed on the side of the oven. When a flame signal is detected, the built-in pointed hammer 12, driven by the gas-generating agent 10, responds in milliseconds to relieve the pressure increase caused by the explosion gas and inhibitor spraying, ensuring smooth and safe inhibitor spraying. Simultaneously, when the inhibitor storage tank 6 receives an accidental explosion flame signal inside the oven, it can respond in milliseconds to release the inhibitor material for explosion control.

[0047] In practice, depressurization and inhibitor spraying are carried out simultaneously, without any specific order.

[0048] Specific example two:

[0049] See attached document Figure 5 As shown, when the pressure-bearing body 1 is a reactor, in the event of an accidental combustion and explosion during reactor operation, the detection sensor 4, which includes a flame sensor and a gas sensor, is placed inside the reactor to detect the accidental combustion and explosion during the operation phase. A nozzle 3 is built into the top of the reactor, and the nozzle 3 is connected to the inhibitor storage tank 6 via an inhibitor delivery pipeline 5. A multi-layer rapid pressure relief assembly 2 is installed on the side of the reactor. When a signal is detected, the built-in pointed hammer 12, driven by the gas-generating agent 10, responds in milliseconds to relieve the pressure increase caused by the combustion and explosion gas and the inhibitor spray, ensuring smooth and safe inhibitor spraying. Simultaneously, when the inhibitor storage tank 6 receives an accidental combustion and explosion signal from inside the reactor, it can respond in milliseconds to release the inhibitor material for combustion and explosion control.

[0050] In practice, depressurization and inhibitor spraying are carried out simultaneously, without any specific order.
