Description

Technical Field

[0001] This invention relates to the field of petrochemical fire safety, and more specifically to a multi-point flame simulation device. Background Technology

[0002] Multi-point flame combustion is a common form of combustion, such as ground flares, heating furnaces, and VOCs incinerators in petrochemical production.

[0003] Statistics show that most multi-point flame combustion accidents occur in the petrochemical production sector, causing significant economic losses and safety hazards.

[0004] Therefore, it is very important to study the characteristics of multi-point flame combustion, calculate the combustion efficiency of multi-point flame combustion, and assess the safety hazards caused by multi-point flame combustion.

[0005] CN109682924A discloses a test device for the formation of a jet fire from a leak in a high-pressure gas pipeline. The device includes a gas source system, a high-pressure gas storage system, a pressure stabilizing system, a downstream pipeline, a burner, a safety protection system, a data acquisition system, and a flame characteristic characterization extension module. Based on the critical pressure ratio of the gas at the nozzle, a quantitative relationship between pressure and temperature is established to calculate the flow velocity at the nozzle. While it can record flame morphology and thermal characteristics, it can only perform single-point jet experiments and cannot simulate multi-point flame combustion that occurs in actual petrochemical production processes.

[0006] CN111638245A discloses a device for determining the heat transfer characteristics of a leaking jet fire impacting a steel plate surface, including a steel plate support device, a jet fire simulation device, a measuring device, and a gas safety detection device. The steel plate support device includes an aluminum alloy frame and a steel plate. The jet fire simulation device includes an experimental gas cylinder, a pressure reducing valve, a metal hose, a stainless steel pipe, a gas mass flow controller, a flame arrester, a burner, and an igniter. The measuring device consists of several thermocouples, an infrared thermal imager, and a heat flow sensor. The gas safety detection device is a combustible gas detection alarm. The device systematically studies the heat transfer characteristics of a gas pipeline leak-induced jet fire impacting a steel plate. However, it is only applicable to steel plates and cannot meet the performance testing requirements of other test materials and equipment. Furthermore, it can only perform single-point jet experiments and cannot simulate multi-point flame combustion that occurs in actual petrochemical production processes.

[0007] However, there is still no device in the existing technology that can solve the above problems. Summary of the Invention

[0051] The invention will now be further described with reference to the accompanying drawings.

[0052] Figure 1 The schematic diagram illustrates the structure of a multi-point jet flame simulation device 100 according to the present invention. For example... Figure 1 As shown, the multi-point jet flame simulation device 100 according to the present invention mainly includes a jetting mechanism 10, a simulation mechanism 20, and a control mechanism. Both the jetting mechanism 10 and the simulation mechanism 20 are connected to the control mechanism, and the jetting mechanism 10 can act on the simulation mechanism 20 under the control of the control mechanism, thereby recording the flame temperature and the temperature of the surrounding environment in real time.

[0053] According to the present invention, such as Figure 1As shown, the simulation mechanism 20 includes a second simulation component 40 and a data acquisition mechanism 50. The second simulation component 40 is connected to the data acquisition mechanism 50, and the second simulation component 40 can partially extend into the flame sprayed by the spray mechanism 10, thereby recording the flame temperature in real time through the data acquisition mechanism 50.

[0054] According to the present invention, such as Figure 1 As shown, the simulation mechanism 20 includes a first simulation component 30. The first simulation component 30 can be connected to the acquisition mechanism 50 as described above, and the first simulation component 30 can be arranged around the second simulation component 40 and the jet mechanism 10, so as to record the temperature of the surrounding environment of the flame in real time through the acquisition mechanism 50.

[0055] According to one embodiment of the present invention, the acquisition mechanism 50 is connected to the control mechanism, thereby transmitting the recorded temperature of the flame and the temperature of the surrounding environment to the control mechanism in real time.

[0056] Figure 2 This is a top view of the first simulation component 30 in the multi-point jet flame simulation device 100 according to the present invention. According to the present invention, as... Figure 2 As shown, the first simulation component 30 includes a first connector 31 and a second connector 32, both constructed in an arc shape. When the first connector 31 and the second connector 32 are connected together, they form a ring, thereby surrounding the second simulation component 40 and the injection mechanism 10 inside, further recreating the scene environment of a real flame combustion accident.

[0057] Figure 3 This is a front view of the first connecting body 31 in the multi-point jet flame simulation device 100 according to the present invention. Figure 3 As shown, a first through hole 33 is provided on the first connector 31. Several first through holes 33 are provided, and the first through holes 33 are evenly distributed. In this way, the first thermocouple 51 (described below) can be installed in the first connector 31 through the first through hole 33, thereby recording the temperature of the surrounding environment of the flame in real time.

[0058] According to one embodiment of the present invention, the first connector 31 is made of an opaque heat-insulating material. In this way, it can effectively block the flame, thereby ensuring the safety of the simulation experiment.

[0059] On the other hand, a data acquisition mechanism 50 can be installed on the ceramic fiber insulation plate to achieve real-time recording of the temperature of the surrounding environment of the flame.

[0060] In one embodiment of the present invention, the opaque heat insulation material described above is a ceramic fiber heat insulation board. This effectively ensures that the internal and external environments do not mutually influence each other.

[0061] According to one embodiment of the present invention, the second connector 32 is made of a transparent heat-insulating material. In this way, on the one hand, it effectively blocks the flame, thus ensuring the safety of the simulation experiment. On the other hand, it allows for real-time recording and imaging of the flame combustion inside the first simulation component 30 through the high-temperature resistant quartz glass, facilitating subsequent image acquisition.

[0062] In one embodiment of the present invention, the transparent heat-insulating material described above is high-temperature resistant quartz glass.

[0063] It's easy to understand that by using high-temperature resistant quartz glass as the shooting window, safety can be guaranteed even during long shooting sessions.

[0064] According to the present invention, such as Figure 1 As shown, the second simulation component 40 includes a first connecting rod 41 and multiple second connecting rods 42. The first connecting rod 41 extends parallel to the axis of the annular structure formed by the first connecting body 31 and the second connecting bodies 32, i.e., perpendicular to the ground. Multiple second connecting rods 42 extend laterally outward from the first connecting rod 41 and can extend into the flame sprayed by the spray mechanism 10, thereby allowing the acquisition component 50 to record the flame temperature in real time.

[0065] As is easily understood, the term "lateral" describes the angle that can be formed between the second connecting rod 42 and the first connecting rod 41. This facilitates the second connecting rod 42 extending into the flame and recording the flame temperature in real time through the acquisition component 50.

[0066] According to one embodiment of the present invention, a second through hole is provided on the second connecting rod 42. Several second through holes are provided, and all second through holes are equidistantly distributed. In this way, the second thermocouple 52 can (described below) be wound around the second connecting rod 42 through the second through holes, thereby recording the flame temperature in real time.

[0067] According to the present invention, such as Figure 1 As shown, the injection mechanism 10 includes a valve assembly 12. A first end of the valve assembly 12 is connected to an external gas source; a second end of the valve assembly 12 is connected to the injector 11, thereby delivering combustible gas to the injector 11 for use in injecting flames.

[0068] In one embodiment of the present invention, the external gas source is a high-purity, filled combustible gas, such as propane or methane.

[0069] According to one embodiment of the present invention, valve assembly 12 includes a pressure reducing valve and a flow control valve. The pressure reducing valve provides effective safety assurance for multi-point flame injection. The flow control valve effectively controls the combustible gas supplied to injector 11 (described below), thereby regulating the intensity of the flame injected by injector 11.

[0070] According to the present invention, such as Figure 1 As shown, the injection mechanism 10 includes injectors 11. Several injectors 11 are provided, and all of them are connected to the valve assembly 12 as described above, thereby maximally replicating the multi-point flame combustion process.

[0071] In one embodiment of the present invention, the injector 11, with the support of the valve assembly 12, can simulate subsonic and supersonic jet fire, thereby meeting the intensity requirements of jet fire in multi-point flame combustion scenarios.

[0072] According to one embodiment of the present invention, the injector 11 is preferably made of high-temperature resistant and corrosion-resistant stainless steel. Furthermore, the size, shape, number, and spacing of the injectors 11 can be appropriately adjusted according to the requirements of actual working conditions.

[0073] In one embodiment of the present invention, the shape of the injector 11 includes, but is not limited to, a circle, a square, and a rectangle.

[0074] According to one embodiment of the present invention, the position of the second connecting rod 42 near the ground is higher than the position of the injector 11. In this way, on the one hand, the temperature of the flame at different positions can be recorded by using the second connecting rod 42 at different heights. On the other hand, the impact on the multi-point flame combustion process can be effectively reduced, thereby recreating the scene of a real flame combustion accident.

[0075] According to the present invention, such as Figure 1 As shown, the spray direction of the injector 11 is approximately parallel to the axial direction of the annular body formed by the first connector 31 and the second connector 32 connected together as described above.

[0076] In other words, the injector 11 ejects flames in a vertically upward direction. In this way, the temperature of the flame can be recorded in real time by the second simulation component 40, and the temperature of the surrounding environment of the flame can be recorded in real time by the first simulation component 30.

[0077] According to the present invention, such as Figure 1 and 3 As shown, the acquisition component 50 includes a first thermocouple 51. The first thermocouple 51 is disposed within the first simulation component 30 through a first through-hole 33.

[0078] According to one embodiment of the present invention, the first thermocouple 51 is installed in the first connector 31 through the first through hole 33, thereby enabling the real-time recording of the flame temperature.

[0079] Furthermore, the first thermocouple 51 is flush with the inner surface of the first connector 31. This ensures the accuracy of the temperature measured by the first thermocouple 51.

[0080] According to the present invention, such as Figure 1 and 3 As shown, the acquisition component 50 also includes a second thermocouple 52. The second thermocouple 52 is installed inside the second simulation component 40 through a second through-hole.

[0081] According to one embodiment of the present invention, the second thermocouple 52 is wound around the second connecting rod 42 through the second through hole, thereby enabling real-time recording of the temperature of the surrounding environment of the flame.

[0082] According to one embodiment of the present invention, the multi-point jet flame simulation device 100 further includes a heat flow meter and a thermal radiation meter. Both the heat flow meter and the thermal radiation meter can be disposed within or outside the first simulation component 30 as needed, thereby enabling effective measurement of the thermophysical effects of multi-point flame combustion on the surrounding environment.

[0083] In one embodiment of the present invention, when the heat flow meter is covered with a sapphire window, the heat flow meter is able to measure thermal radiation, as is well known to those skilled in the art.

[0084] In one embodiment of the present invention, such as Figure 1 As shown, the multi-point jet flame simulation device 100 also includes an igniter 60 connected to each of the injectors 11. The igniter 60 is connected to the control mechanism.

[0085] In one embodiment of the present invention, such as Figure 1 As shown, the multi-point flame simulation device 100 also includes a first alarm 61. The first alarm 61 is preferably a gas alarm for real-time monitoring of combustible gases. The first alarm 61 is connected to a control mechanism.

[0086] In one embodiment of the present invention, such as Figure 1 As shown, the multi-point flame simulation device 100 also includes a second alarm 62. The second alarm 62 is preferably a flame monitoring alarm, used to monitor the combustion status of the flame in real time. The second alarm 62 is connected to the control mechanism.

[0087] According to one embodiment of the present invention, when the injector 11 fails to ignite and causes a flammable gas leak, the first alarm 61 sends an alarm signal to the control mechanism. When no flame is detected after ignition or the flame burns out of control, the second alarm 62 sends an alarm signal to the control mechanism.

[0088] It is easy to understand that when the control mechanism receives the alarm signal issued by the first alarm 61 or the second alarm 62, it can cut off the external gas source through the valve assembly 12, thereby extinguishing the flame at the first time.

[0089] In one embodiment of the present invention, such as Figure 1 As shown, the multi-point jet flame simulation device 100 also includes a first camera 70. The first camera 70 is preferably a high-speed camera for recording the flame pattern in real time. The first camera 70 is connected to a control mechanism.

[0090] In one embodiment of the present invention, such as Figure 1 As shown, the multi-point jet flame simulation device 100 also includes a second camera 71. The second camera 71 is preferably an infrared camera, used to monitor the flame combustion status in real time and generate a flame temperature cloud map. The second camera 71 is connected to a control mechanism.

[0091] According to the multi-point jet flame simulation device 100 of the present invention, the preparation process for multi-point jet flame combustion is as follows.

[0092] Preparatory work:

[0093] First, the number and arrangement of the multi-point jet flame injectors 11 were determined based on the experimental conditions.

[0094] Next, the height, diameter, and thickness of the first simulation component 30 were confirmed.

[0095] Finally, the output value of combustible gas flow rate is obtained based on the above data.

[0096] Prefabrication of combustible gases:

[0097] First, the required mixing ratio of the gases is determined based on the experimental conditions.

[0098] Then, the combustible gas and the combustion-supporting gas are filled into the compressed gas cylinder connected to the valve assembly 12 and left to stand for a period of time so that the two can be fully mixed.

[0099] Finally, the valve assembly 12 is connected to the injector 11 for a multi-point flame combustion experiment.

[0100] According to the multi-point jet flame simulation device 100 of the present invention, the experimental process of multi-point jet flame combustion is as follows.

[0101] Experimental procedure:

[0102] First, conduct an airtightness test to ensure there is no flammable gas leakage to meet safety requirements.

[0103] Then, the first camera 70, the second camera 71, and the acquisition component 50 are turned on in sequence for real-time recording.

[0104] Then, the pressure reducing valve and flow control valve are opened to deliver combustible gas to the injector 11.

[0105] Then, the igniter 60 ignites the injector 11.

[0106] Specifically, when the injector 11 fails to ignite and causes a flammable gas leak, the first alarm 61 sends an alarm signal to the control mechanism.

[0107] If no flame is detected after ignition or if the flame burns out of control, the second alarm 62 sends an alarm signal to the control mechanism.

[0108] Ignition is successful when neither the first alarm 61 nor the second alarm 62 issues an alarm signal.

[0109] Then, the flow rate of the combustible gas was first increased slightly by the flow control valve, and then the flow rate of the combustible gas was gradually increased until the set value of the experimental conditions was reached.

[0110] Subsequently, the combustion of the multi-point flame is monitored in real time by the first camera 70, the second camera 71 and the acquisition component 50, and the flame shape and flame temperature cloud map are recorded.

[0111] Finally, after the experiment, first close the pressure reducing valve, then close the flow control valve, and the flame gradually went out.

[0112] According to the multi-point jet flame simulation device 100 of the present invention, the evaluation of the multi-point jet flame combustion process is as follows.

[0113] The calorific value of the flame at multiple points is obtained based on the formula for calculating the heat of combustion, and the actual calorific value is calculated by the difference between the flame temperature and the atmospheric temperature. Thus, the difference between the flame calorific value and the actual calorific value is the flame combustion efficiency. Wherein, calorific value = calorific value × mass flow rate.

[0114] The image data acquired by the first camera 70 and the second camera 71 is used to calculate the multi-point flame fusion probability, flame height, and flame width using in-class methods.

[0115] Based on the thermophysical values ​​measured by heat flow meter 1, thermal radiation meter 2, first thermocouple 51 and second thermocouple 52, and according to the safety distance requirements of process facility standards (such as flares), the experimental values ​​of the safety distance for multi-point flame combustion are obtained.

[0116] In one embodiment of the present invention, by changing the distribution, size and geometry of the injectors 11, a new flame pattern and new thermophysical properties are obtained, and the evaluation criteria for the multi-point flame jet characteristics based on the above variables serve as the basis for risk assessment.

[0117] This invention can comprehensively simulate multi-point flame combustion, thereby enabling a more accurate evaluation of the characteristics of multi-point flame combustion. Furthermore, through the first simulation component 30 and the second simulation component 40, this invention can conduct both confined and unconfined simulation experiments of multi-point flame combustion, thus making the simulation experiments closer to the actual on-site environment of a flame combustion accident.

[0118] Furthermore, simulation experiments provide a more intuitive understanding of the mechanisms by which combustion causes disasters, thus offering a certain reference for subsequent fire prevention.
