Description

Technical Field

[0001] The invention relates to the technical field of fire safety, in particular to a positioning fire extinguishing system based on aerosol and perfluorohexanone. Background Art

[0002] With the advancement of global energy transformation and the widespread application of renewable energy, energy storage technology, as a key means to solve the problem of new energy consumption, has become increasingly important; especially in the industrial and commercial fields, the potential of the energy storage market is particularly huge, and the installed capacity is growing rapidly; the resulting fire safety is also crucial.

[0003] The current fire detection system performs temperature detection based on the corresponding temperature detection method. When the temperature of the corresponding area exceeds the specified value, the relevant fire extinguishing procedure is activated to extinguish the fire automatically. However, the original method does not simultaneously involve the dual fire extinguishing method of aerosol plus perfluorohexanone to achieve the effect of dual fire extinguishing. In addition, in the actual fire extinguishing process, there are relevant differences in the specific accuracy of its fire extinguishing coverage, and its accuracy needs to be enhanced. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a positioning fire extinguishing system based on aerosol and perfluorohexanone, which solves the problem that there are relevant differences in the specific accuracy of fire extinguishing coverage and its accuracy needs to be enhanced.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a positioning fire extinguishing system based on aerosol plus perfluorohexanone, comprising:

[0006] A temperature sensor is arranged on the fire extinguishing equipment to monitor the temperature at a designated position around the fire extinguishing equipment in real time, and transmit the real-time monitored temperature to the active control module. The fire extinguishing equipment includes a hot aerosol fire extinguishing device and a perfluorohexanone fire extinguishing device. A large amount of hot aerosol is stored in the hot aerosol fire extinguishing device, and a large amount of perfluorohexanone is stored in the perfluorohexanone fire extinguishing device.

[0007] The active control module, based on the real-time monitored temperature, assesses whether the conditions for opening the hot aerosol fire extinguishing device are met, generates a processing instruction after opening the hot aerosol fire extinguishing device, and then transmits the processing instruction to the infrared detection sensor unit. The specific method is as follows:

[0008] The real-time monitored temperature is calibrated as WD i , where i represents different moments, and the real-time monitored temperature WD i Compare with the preset value Y1:

[0009] When WD iWhen ≥Y1, the hot aerosol fire extinguishing device is directly turned on to release hot aerosol to carry out preliminary fire extinguishing treatment in the surrounding area. After the release is completed, a processing instruction is generated and transmitted to the infrared detection sensor unit;

[0010] When WD i When <Y1, no processing is performed;

[0011] The infrared detection sensor unit, based on the received processing instructions, performs infrared detection on the surrounding area of ​​the fire extinguishing equipment, determines the detection temperature at different points in the surrounding area, and locks the fire source area based on the specific detection temperature. The specific method is as follows:

[0012] Based on infrared detection sensors, the detected temperature at different points in the surrounding area is confirmed and calibrated as TC k , where k represents different points;

[0013] The detected temperature TC k Compare with the preset standard temperature Bz, where Bz is the preset value. k >Bz, mark this point as an abnormal point. If TC k ≤Bz, no treatment is performed;

[0014] Based on the calibrated groups of abnormal points, the areas associated with the groups of abnormal points are calibrated as fire source areas, and the determined fire source areas are transmitted to the area contour processing unit;

[0015] The area contour processing unit confirms the center point of the fire source area based on the determined fire source area, and locks the spatial coordinate point based on the determined center point, and transmits the confirmed spatial coordinate point to the spatial coordinate processing unit, specifically in the following manner:

[0016] Based on the determined fire source area, the peripheral contour of the fire source area is decomposed into a number of contour points, the overall peripheral contour of the fire source area is placed in a set of three-dimensional coordinate systems, and the point coordinates of each different contour point are obtained based on the three-dimensional coordinate system and calibrated as Lq(Xq, Yq, Zq), where q=1, 2, ..., n, and n represents the total number of the contour points;

[0017] The point coordinates of several contour points are processed by averaging to determine their mean coordinates: Xj = (X1 + X2 + ... + Xn) ÷ n, Yj = (Y1 + Y2 + ... + Yn) ÷ n, Zj = (Z1 + Z2 + ... + Zn) ÷ n, and the mean point Jz is locked based on the determined mean coordinates Xj, Yj and Zj;

[0018] Based on the determined mean point Jz and the corresponding mean coordinates, the corresponding spatial point is determined, and the determined spatial point is transmitted to the spatial coordinate processing unit;

[0019] The spatial coordinate processing unit determines the adjustment angle based on the determined spatial point position and the specific position of the fire extinguishing equipment, and then transmits the adjustment angle to the active control module based on the determined adjustment angle, and the active control module adjusts the injection angle of the perfluorohexanone fire extinguishing device based on the adjustment angle; the specific method is:

[0020] Based on the positioning sensor in the fire extinguishing equipment, the specific position of the fire extinguishing equipment is locked and the positioning point is determined, and the positioning point and the spatial point are located in the same two-dimensional plane;

[0021] Determine the two-dimensional horizontal plane where the positioning point is located, then construct a perpendicular line between the spatial point and the two-dimensional horizontal plane and determine the perpendicular point, connect the perpendicular point with the positioning point based on the determined perpendicular point, determine a horizontal connecting line, then interconnect the positioning point with the spatial point, determine an oblique connecting line, and determine a set of right triangles based on the oblique connecting line, the horizontal connecting line and the perpendicular line;

[0022] The angle between the oblique connecting line and the horizontal connecting line is determined from the right triangle based on trigonometric functions, and the angle is calibrated as an adjustment angle, and the adjustment angle is transmitted to the active control module.

[0023] Preferably, the active control module preferentially adjusts the injection port of the fire extinguishing equipment to a state parallel to the two-dimensional plane, and then adjusts the injection angle of the injection port based on the determined adjustment angle. After the adjustment is completed, the ejection of perfluorohexanone inside the perfluorohexanone fire extinguishing device is controlled.

[0024] The present invention provides a positioning fire extinguishing system based on aerosol plus perfluorohexanone. Compared with the prior art, it has the following beneficial effects:

[0025] The present invention preferentially uses a hot aerosol fire extinguishing device for preliminary fire extinguishing to prevent the fire from spreading, and then uses a perfluorohexanone fire extinguishing device to extinguish the fire source area. Through this linkage control mechanism, our fire extinguishing system can provide double protection to ensure that when a fire occurs, the fire extinguishing operation can be carried out quickly and effectively to minimize property losses and personal injuries.

[0026] By determining the overall contour of the fire source area and the corresponding area, locking the corresponding contour line, and then determining the relevant contour points based on the corresponding contour line, locking the point coordinates of the contour points in the two-dimensional coordinate system, and then adjusting the angle, the sprayed perfluorohexanone can accurately reach the designated fire source center point, and fully extinguish the relevant fire source area around the fire source center point, so as to achieve better fire extinguishing treatment effect and fully guarantee the accuracy and range of fire extinguishing.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] First embodiment

[0032] See also Figure 1 , the present application provides a positioning fire extinguishing system based on aerosol plus perfluorohexanone, comprising a temperature sensor, an active control module, an infrared detection sensor unit, a regional contour processing unit and a spatial coordinate processing unit, wherein the temperature sensor, the active control module, the infrared detection sensor unit, the regional contour processing unit and the spatial coordinate processing unit, wherein the temperature sensor is electrically connected to an input node of the active control module, the active control module is electrically connected to an input node of the infrared detection sensor unit, and the infrared detection sensor unit, the regional contour processing unit, the spatial coordinate processing unit and the active control module are electrically connected in sequence from an output node to an input node;

[0033] The temperature sensor is arranged on the fire extinguishing equipment to monitor the temperature at the designated position around the fire extinguishing equipment in real time, and transmit the real-time monitored temperature to the active control module. Specifically, the monitored temperature can be understood as the surface temperature of the equipment surface. Based on the corresponding sensor, the temperature of the fire extinguishing area can be monitored in real time. When the temperature reaches the standard, the corresponding fire extinguishing device needs to be turned on to carry out relevant fire extinguishing.

[0034] The fire extinguishing equipment includes a hot aerosol fire extinguishing device and a perfluorohexanone fire extinguishing device. A large amount of hot aerosol is stored in the hot aerosol fire extinguishing device. After the hot aerosol fire extinguishing device is turned on, the hot aerosol inside undergoes an oxidation-reduction reaction, and a large amount of condensed fire extinguishing aerosol is formed in the surrounding area, which can quickly and effectively cover the fire source and suppress the spread of the flame.

[0035] Schematic diagram of perfluorohexanone fire extinguishing device Figure 3 As shown, perfluorohexanone fire extinguishing agent is a colorless transparent liquid at room temperature, with a boiling point of about 49°C, a latent heat of evaporation of 1 / 25 of that of water, and is very easy to vaporize. It has high fire extinguishing efficiency (equivalent to Halon-1301), no activity to ozone (ozone depletion potential value ODP = 0), a greenhouse effect index (GWP) of only 1, a NOAEL of 10%, which is greater than 72-122% of its fire extinguishing concentration, and is non-conductive. The parameter table of the perfluorohexanone fire extinguishing device is as follows:

[0036] Model Specifications YF-4 / 2.5N-KD Total amount of fire extinguishing agent 3-6KG Dimensions Φ140-475mm Maximum working pressure 3.2MPa(65℃) Storage pressure 2.5MPa(20℃) Drive mode Nitrogen driven Startup method Electric Explosion Start Rated voltage 24V Starting current ≥600mA Spraying time ≤10S Bottle material Aluminum Alloy Spraying times 1 time

[0037] Table 1 (Perfluorohexanone fire extinguishing device parameter table);

[0038] The hot aerosol fire extinguishing device is a breakthrough product in the fire protection field with ultra-high fire extinguishing efficiency and reliability. The product has the characteristics of small size, pressure-free storage, no need to lay pipes and maintenance, efficient and rapid fire extinguishing, non-toxic and harmless, safe and reliable, green and environmentally friendly, etc. It is particularly suitable for relatively closed places such as communication rooms, battery compartments, engine compartments, battery boxes, etc.

[0039] The fire suppression effect of S-type thermal aerosol is mainly reflected in the following aspects:

[0040] The fire extinguishing mechanisms of general fire extinguishing agents mainly include isolation, asphyxiation, cooling, and chemical inhibition. Different fire extinguishing agents have different fire extinguishing mechanisms. The fire extinguishing mechanism of thermal aerosols is mainly reflected in two aspects: on the one hand, the cooling effect of endothermic decomposition, and on the other hand, the chemical inhibition of gas phase and solid phase, which work together. In addition, the gas phase components in the aerosol fire extinguishing agent product also play a certain auxiliary role.

[0041] ⑴ Cooling and fire extinguishing effect of endothermic decomposition

[0042] The cooling effect of thermal aerosol fire extinguishing agents mainly relies on the endothermic decomposition of four metal oxides and carbonates. The heat released by any fire in a short period of time is limited. If the solid particles in the aerosol can absorb part of the heat released by the fire source in a short period of time, the temperature of the flame will be reduced, and the heat radiated to the combustion surface and used to crack the already gasified combustible molecules into free radicals will be reduced, and the combustion reaction will be inhibited to a certain extent.

[0043] ⑵Gas phase chemical inhibition

[0044] Under the action of heat, the gasified metal ions such as Sr, K, Mg or cations that have lost electrons from the hot aerosol extinguishing and decomposition exist in the form of steam, and undergo multiple chain reactions with the active groups H·, ·OH and O· in the combustion. The following takes Sr as an example:

[0045] Sr+2·OH→Sr(OH)Sr+O·→SrOSr(OH)2+2H→Sr+2H2O

[0046] This process is repeated many times, and the active groups in combustion are consumed in large quantities, the concentration continues to decrease, and combustion is suppressed.

[0047] ⑶Solid phase chemical inhibition

[0048] The solid particles in the hot aerosol fire extinguishing agent can adsorb the chain reaction intermediates OH, H and O, and catalyze them to reconstitute stable molecules, thereby terminating the branch chain reaction of the combustion process. Taking K as an example, it is as follows:

[0049] K2O(s)+2H(g)→2KOH(s)KOH(s)+OH(s)→KO(s)+H2O(s)

[0050] K2O(s)+O(g)→2KOKO(s)+H(g)→KOH

[0051] In the above-mentioned fire extinguishing effect, several fire extinguishing mechanisms interact and work synergistically, but the gas transmission effect and the heat absorption and cooling effect of metal oxides or carbonates only play an auxiliary effect, and the main fire extinguishing effect still depends on the chemical inhibition of gas and solid phases.

[0052] The perfluorohexanone fire extinguishing device is used as a secondary fire extinguishing means. It can further ensure that the fire source is completely extinguished after the hot aerosol fire extinguishing device initially controls the fire.

[0053] Through the linkage control mechanism of the hot aerosol fire extinguishing device and the perfluorohexanone fire extinguishing device, double protection can be provided for the fire extinguishing system, ensuring that when a fire occurs, fire extinguishing operations can be carried out quickly and effectively to minimize property losses and personal injuries.

[0054] Among them, combined Figure 2 The active control module, based on the real-time monitored temperature, assesses whether the conditions for opening the hot aerosol fire extinguishing device are met. When the hot aerosol fire extinguishing device is opened, a processing instruction is generated and transmitted to the infrared detection sensor unit. The specific way of assessment is as follows:

[0055] The real-time monitored temperature is calibrated as WD i, where i represents different moments, and the real-time monitored temperature WD i Compare with the preset value Y1:

[0056] When WD i When <Y1, no processing is performed;

[0057] When WD i When ≥Y1, the hot aerosol fire extinguishing device is directly turned on to release hot aerosol to carry out preliminary fire extinguishing treatment in the surrounding area. After the release is completed, the processing instructions are generated and transmitted to the infrared detection sensor unit.

[0058] Specifically, when the associated monitoring temperature reaches the set value, the designated door needs to be opened to release the gas and preliminarily cover the surrounding fire sources to prevent the spread of the corresponding fire sources, so as to achieve a better fire extinguishing effect. Subsequently, targeted fire extinguishing is carried out based on the location of the fire source to ensure that the corresponding fire source can be fully extinguished.

[0059] Among them, the infrared detection sensor unit, based on the received processing instructions, performs infrared detection on the surrounding area of ​​the fire extinguishing equipment, determines the detection temperature of different points in the surrounding area, and locks the fire source area based on the specific detection temperature. Specifically, for the fire source area, it is necessary to lock the temperature exceeding the standard area based on the corresponding temperature performance and the set preset value, and determine the fire source area by locking the temperature exceeding the standard area. The specific method of locking the fire source area is:

[0060] Based on infrared detection sensors, the detected temperature at different points in the surrounding area is confirmed and calibrated as TC k , where k represents different points;

[0061] The detected temperature TC k Compare with the preset standard temperature Bz, where Bz is the preset value, and its specific value is determined by the operator based on experience. k >Bz, mark this point as an abnormal point. If TC k ≤Bz, no treatment is performed;

[0062] Based on the calibrated groups of abnormal points, the areas associated with the groups of abnormal points are calibrated as fire source areas, and the determined fire source areas are transmitted to the area contour processing unit;

[0063] Specifically, its infrared detection can detect the relevant temperature emitted by the corresponding object, and identify and determine the relevant abnormal points based on the temperature data of the specific points, so that the corresponding fire source area can be locked based on the specific coverage area of ​​the abnormal points.

[0064] The regional contour processing unit confirms the center point of the fire source area based on the determined fire source area, and locks the spatial coordinate point based on the determined center point, and transmits the confirmed spatial coordinate point to the spatial coordinate processing unit. The specific method of confirming the center point is:

[0065] Based on the determined fire source area, the peripheral contour of the fire source area is decomposed into a number of contour points (its edge contour can be understood as a corresponding curve, and the corresponding curve is composed of a number of points, that is, a line is composed of a number of points), and the overall peripheral contour of the fire source area is placed in a set of three-dimensional coordinate systems, and the point coordinates of each different contour point are obtained based on the three-dimensional coordinate system, and calibrated as Lq (Xq, Yq, Zq), where q = 1, 2, ..., n, and n represents the total number of the contour points;

[0066] The point coordinates of several contour points are processed by averaging to determine their mean coordinates: Xj = (X1 + X2 + ... + Xn) ÷ n, Yj = (Y1 + Y2 + ... + Yn) ÷ n, Zj = (Z1 + Z2 + ... + Zn) ÷ n, and the mean point Jz is locked based on the determined mean coordinates Xj, Yj and Zj;

[0067] Based on the determined mean point Jz and the corresponding mean coordinates, the corresponding spatial point is determined, and the determined spatial point is transmitted to the spatial coordinate processing unit.

[0068] The corresponding fire source area has a corresponding area contour, and the corresponding area contour is composed of relevant curves, and the relevant curves are composed of several points. Each different point can determine the corresponding three-dimensional point in the three-dimensional space coordinate system, and the three-dimensional point has three-dimensional coordinates. By performing relevant mean processing on several three-dimensional coordinates, the corresponding mean coordinates can be directly locked. After the corresponding mean coordinates are determined, the relevant mean points can be locked. The determined mean point is the center point of the corresponding fire source area. After the center point is specifically confirmed, the spatial coordinates can be specifically confirmed, and specific related controls can be carried out.

[0069] Second embodiment

[0070] The spatial coordinate processing unit determines the adjustment angle based on the determined spatial point position and the specific position of the fire extinguishing equipment, and then transmits the adjustment angle to the active control module based on the determined adjustment angle. The active control module adjusts the injection angle of the perfluorohexanone fire extinguishing device based on the adjustment angle. The specific method of determining the adjustment angle is:

[0071] Based on the positioning sensor in the fire extinguishing equipment, the specific position of the fire extinguishing equipment is locked and the positioning point is determined, and the positioning point and the spatial point are located in the same two-dimensional plane;

[0072] Determine the two-dimensional horizontal plane where the positioning point is located, then construct a perpendicular line between the spatial point and the two-dimensional horizontal plane and determine the perpendicular point, connect the perpendicular point with the positioning point based on the determined perpendicular point, determine a horizontal connecting line, then interconnect the positioning point with the spatial point, determine an oblique connecting line, and determine a set of right triangles based on the oblique connecting line, the horizontal connecting line and the perpendicular line;

[0073] The angle between the oblique connecting line and the horizontal connecting line is determined from the right triangle based on trigonometric functions, and the angle is calibrated as an adjustment angle, and the adjustment angle is transmitted to the active control module.

[0074] The active control module preferentially adjusts the nozzle of the fire extinguishing equipment to a state parallel to the two-dimensional plane, and then adjusts the spray angle of the nozzle based on the determined adjustment angle. After the adjustment is completed, the perfluorohexanone inside the perfluorohexanone fire extinguishing device is controlled to spray out to extinguish the fire source area.

[0075] Specifically, the fire extinguishing equipment has its own transmission mechanism inside, which can drive the nozzle to rotate. During the rotation process, the nozzle can be made parallel to the two-dimensional plane. After the initial adjustment is completed, the injection angle of the relevant nozzle is specifically adjusted and confirmed through a specific control module. Based on the specific adjustment process, the corresponding nozzle reaches the optimal injection state, so that perfluorohexanone can fully cover the fire source area, thereby achieving a better fire extinguishing effect.

[0076] Some of the data in the above formulas are dimensionless and numerically calculated. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0077] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
