Description
技术领域technical field
本发明涉及消防技术领域，具体涉及一种电力小微空间用灭火系统。The invention relates to the technical field of fire protection, in particular to a fire extinguishing system for electric small and micro spaces.
背景技术Background technique
近些年电气火灾频发。根据对电气火灾事故案例的调查，该类火灾大多是从开关柜、环网柜、电缆沟（桥架）、箱式变压器等电力小微空间内部引发。这些火灾常起源于电缆、电力变压器等电气设备故障，通过烟气热辐射及火蔓延发展成建筑物内或公共场合大型火灾。为了避免电气火灾蔓延导致较大事故，现今亟需在开关柜、环网柜、电缆沟（桥架）、箱式变压器等极易发生火灾的电力小微空间内设计、安装小型自动灭火装置，在该类场所出现火灾故障时，达到自动灭火的效果，确保电力设备的安全。Electrical fires have occurred frequently in recent years. According to the investigation of electrical fire accident cases, most of these fires are caused from inside small and micro spaces such as switch cabinets, ring network cabinets, cable trenches (bridges), and box-type transformers. These fires often originate from the failure of electrical equipment such as cables and power transformers, and develop into large-scale fires in buildings or public places through heat radiation and fire spread of smoke. In order to avoid large accidents caused by the spread of electrical fires, it is urgent to design and install small-scale automatic fire extinguishing devices in switch cabinets, ring network cabinets, cable trenches (bridges), box-type transformers and other small and micro power spaces that are prone to fire. When a fire failure occurs in such places, it can achieve the effect of automatic fire extinguishing and ensure the safety of electric equipment.
电力小微空间的火灾保护需要满足如下条件：（1）灭火高效，快速扑灭火灾。（2）具有清洁的灭火能力，电力设备中有较多的电气元件，不能因灭火造成污染或损坏，且火灾后应容易处理。（3）环保性较好，由于电力小微空间常位于高楼建筑中的电缆竖井、配电间，以及路边有行人出入的电缆沟、配电变压器、环网柜等，因此需要灭火系统对环境和人体的危害小。（4）安全性高，稳定性好，由于配电变压器、电缆沟、环网柜等发生火灾时常伴随电气设备的爆炸，因此要求灭火系统本身安全性高、稳定性好，不会由于爆炸冲击造成二次爆炸伤害。而且，灭火系统置于室外，需要在户外高温下长期保持稳定。Fire protection in small and micro spaces of electric power needs to meet the following conditions: (1) Efficient fire extinguishing and fire extinguishment quickly. (2) It has a clean fire extinguishing ability. There are many electrical components in the power equipment, which cannot be polluted or damaged by fire extinguishing, and should be easy to handle after a fire. (3) Environmental protection is good. Since small and micro spaces for electric power are often located in cable shafts and power distribution rooms in high-rise buildings, as well as cable trenches, distribution transformers, and ring network cabinets where pedestrians enter and exit on the roadside, it is necessary for the fire extinguishing system to The harm to the environment and human body is small. (4) High safety and good stability. Since fires in distribution transformers, cable trenches, ring network cabinets, etc. are often accompanied by explosions of electrical equipment, it is required that the fire extinguishing system itself has high safety and good stability, and will not be impacted by explosions. Deals secondary explosion damage. Moreover, the fire extinguishing system is placed outdoors and needs to be stable for a long time under high outdoor temperatures.
现今常用的小微空间灭火技术包括气溶胶、干粉、七氟丙烷、二氧化碳、氮气、IG541等。但是，气溶胶灭火系统喷放的烟雾可能对电气设备绝缘造成影响，且长期在高温等复杂环境下运行存在一定的爆炸和误动作风险。干粉灭火剂使用有效期短，且喷放后污染电气设备。气体灭火剂释放后可随空气飘散，因此清洁性好，适合应用于电力小微空间的灭火应用。但是，二氧化碳、氮气气体的灭火效率低。七氟丙烷、六氟丙烷、三氟甲烷环保性不好，对人身安全具有较大的危害。而且，七氟丙烷的释放压力在2.5MPa以上，二氧化碳、氮气、IG541的释放压力均在4MPa以上，压力较高；气体灭火装置置于电力小微空间，当火灾或爆炸发生时，由于灭火装置本身压力高，可能由于受热或爆炸冲击导致二次爆炸，因此灭火应用安全性低，存在安全隐患。综上所述，现今亟需一种灭火效率高、环保性好、安全性高的气体灭火系统。Today's commonly used small and micro space fire extinguishing technologies include aerosol, dry powder, heptafluoropropane, carbon dioxide, nitrogen, IG541, etc. However, the smoke emitted by the aerosol fire extinguishing system may affect the insulation of electrical equipment, and there is a certain risk of explosion and malfunction in long-term operation in complex environments such as high temperature. The dry powder fire extinguishing agent has a short validity period and pollutes electrical equipment after spraying. After the gas fire extinguishing agent is released, it can float with the air, so it has good cleanliness and is suitable for fire extinguishing applications in small and micro spaces of electric power. However, the fire extinguishing efficiency of carbon dioxide and nitrogen gas is low. Heptafluoropropane, hexafluoropropane, and trifluoromethane are not environmentally friendly and pose a greater hazard to personal safety. Moreover, the release pressure of heptafluoropropane is above 2.5 MPa, and the release pressure of carbon dioxide, nitrogen, and IG541 are all above 4 MPa, which is relatively high; the gas fire extinguishing device is placed in the small and micro space of the electric power. When a fire or explosion occurs, due to the pressure of the fire extinguishing device itself High, it may cause secondary explosion due to heat or explosion shock, so the safety of fire extinguishing application is low, and there are potential safety hazards. To sum up, there is an urgent need for a gas fire extinguishing system with high fire extinguishing efficiency, good environmental protection and high safety.
发明内容Contents of the invention
本发明要解决的技术问题是克服现有技术的不足，提供一种灭火效率高、安全性高、结构简单、操作简便、经济性好的电力小微空间用灭火系统。The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a fire extinguishing system for electric small and micro spaces with high fire extinguishing efficiency, high safety, simple structure, easy operation and good economy.
为解决上述技术问题，本发明采用以下技术方案：In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions:
一种电力小微空间用灭火系统，包括灭火剂容器、撞击式雾化喷头、灭火剂释放控制阀和用于探测电力小微空间内火灾的火灾探测模块，所述灭火剂容器内装有由灭火液和惰性气体混合而成的低压灭火剂，所述撞击式雾化喷头通过灭火剂释放管与灭火剂容器的内腔连通，所述灭火剂释放控制阀设于所述灭火剂释放管上并与火灾探测模块相连，所述灭火剂释放控制阀接收到火灾探测模块的火灾信号后开启，灭火剂容器中的低压灭火剂经灭火剂释放管由所述撞击式雾化喷头撞击雾化喷出。撞击式雾化喷头可以增大灭火剂的蒸发表面积，实现快速雾化后气化灭火，同时也使得容器中低压灭火剂的存储压力可为较低的状态。A fire extinguishing system for small and micro electric power spaces, comprising a fire extinguishing agent container, an impact atomizing nozzle, a fire extinguishing agent release control valve and a fire detection module for detecting fires in small and micro electric power spaces, the fire extinguishing agent container is equipped with fire extinguishing It is a low-pressure fire extinguishing agent mixed with liquid and inert gas. The impact atomizing nozzle communicates with the inner cavity of the fire extinguishing agent container through the fire extinguishing agent release pipe. The fire extinguishing agent release control valve is arranged on the fire extinguishing agent release pipe and Connected to the fire detection module, the fire extinguishing agent release control valve is opened after receiving the fire signal from the fire detection module, and the low-pressure fire extinguishing agent in the fire extinguishing agent container is sprayed by the impact atomizing nozzle through the fire extinguishing agent release pipe . The impingement atomizing nozzle can increase the evaporation surface area of the fire extinguishing agent, realize quick atomization and gasification fire extinguishing, and also make the storage pressure of the low-pressure fire extinguishing agent in the container can be in a lower state.
作为上述技术方案的进一步改进：As a further improvement of the above technical solution:
优选的，所述灭火剂容器上设有实时监测其内灭火剂压力的压力表。Preferably, the fire extinguishing agent container is provided with a pressure gauge for real-time monitoring of the pressure of the fire extinguishing agent inside.
优选的，所述灭火剂容器中低压灭火剂的存储压力为0.35-1.5 MPa（更优选为0.5-1.0 MPa），可保证灭火系统在较低的安全压力下使用。Preferably, the storage pressure of the low-pressure fire extinguishing agent in the fire extinguishing agent container is 0.35-1.5 MPa (more preferably 0.5-1.0 MPa), which can ensure that the fire extinguishing system can be used at a lower safe pressure.
优选的，所述灭火剂为全氟已酮和惰性气体的混合物，所述惰性气体为氮气、氦气、氩气中的一种或多种。全氟已酮是一种无色无味的新型灭火剂，其臭氧损耗潜能值（ODP）等于0，全球温室效应潜能值（GWP）为1，大气存活寿命（年）为0.014（5天），因此环保性能很好。并且，全氟已酮的沸点为48-49℃，稳定性高，在受热情况下实现气化吸热灭火，灭火后无残留，清洁性好。另外，全氟已酮在常温下是液体，存储压力低，安全性能高，因此适合应用于电力小微空间的安全、清洁灭火。但是，由于全氟已酮的气化温度高，因此不能像其它气体灭火剂一样，直接凭借自身气体压力喷出灭火，而需要混合其它惰性气体，利用气体的压力，辅助其喷出并气化灭火。全氟已酮与惰性气体混合的混合方式为：首先，于常温常压下，在容器中添加体积分数为50-70%的全氟已酮灭火剂；然后，在密闭容器中填充惰性气体至一定压力。Preferably, the fire extinguishing agent is a mixture of perfluorohexanone and an inert gas, and the inert gas is one or more of nitrogen, helium, and argon. Perfluorohexanone is a new colorless and odorless fire extinguishing agent. Its ozone depletion potential (ODP) is equal to 0, its global warming potential (GWP) is 1, and its atmospheric survival life (year) is 0.014 (5 days). Therefore, the environmental protection performance is very good. In addition, perfluorohexanone has a boiling point of 48-49°C, high stability, and can realize gasification and endothermic fire extinguishing when heated. There is no residue after fire extinguishing, and the cleaning performance is good. In addition, perfluorohexanone is a liquid at room temperature, with low storage pressure and high safety performance, so it is suitable for safe and clean fire extinguishing in small and micro spaces of electric power. However, due to the high vaporization temperature of perfluorohexanone, it cannot be sprayed out directly by its own gas pressure to extinguish the fire like other gas fire extinguishing agents, but needs to be mixed with other inert gases to use the pressure of the gas to assist its spraying and gasification Extinguishing. The mixing method of perfluorohexanone and inert gas is: first, at normal temperature and pressure, add perfluorohexanone fire extinguishing agent with a volume fraction of 50-70% in the container; then, fill the airtight container with inert gas to Certain pressure.
惰性气体优选氮气、氦气、氩气中一种或多种混合物的原因为：研究发现，这些气体的压力随温度的变化小，如氮气，当环境温度从10℃上升至30℃时，气体压力上升少于10%，应用安全性能高。而对于二氧化碳气体，当环境温度为10℃上升至30℃时，气体压力可上升60%。因此，二氧化碳气体在温度变化过大时存在压力骤然上升的风险，应用安全性能低。The reason why the inert gas is preferably one or more mixtures of nitrogen, helium, and argon is that the research has found that the pressure of these gases changes little with temperature, such as nitrogen, when the ambient temperature rises from 10°C to 30°C, the gas The pressure rise is less than 10%, and the application safety performance is high. For carbon dioxide gas, when the ambient temperature rises from 10°C to 30°C, the gas pressure can increase by 60%. Therefore, when the temperature of carbon dioxide gas changes too much, there is a risk of sudden pressure rise, and the application safety performance is low.
优选的，所述的火灾探测模块为温度传感器、红外火焰传感器、火探管中的一种或多种的组合。Preferably, the fire detection module is one or a combination of temperature sensors, infrared flame sensors, and fire detection tubes.
优选的，所述的灭火剂释放控制阀为气动式气体释放阀或电磁式气体释放阀。Preferably, the fire extinguishing agent release control valve is a pneumatic gas release valve or an electromagnetic gas release valve.
优选的，所述的灭火剂释放管采用耐腐蚀和火灾温度的铜管、不锈钢管或金属合金管。Preferably, the fire extinguishing agent release pipe adopts copper pipe, stainless steel pipe or metal alloy pipe that is resistant to corrosion and fire temperature.
优选的，所述撞击式雾化喷头包括灭火剂释放孔、圆锥撞击体及支撑平台，所述灭火剂释放孔的入口端与灭火剂释放管连通，所述圆锥撞击体的大端装设于支撑平台上，圆锥撞击体的尖端正对灭火剂释放孔的出口端。Preferably, the percussion atomizing nozzle includes a fire extinguishing agent release hole, a conical impact body and a support platform, the entrance end of the fire extinguishing agent release hole communicates with the fire extinguishing agent release pipe, and the large end of the cone impact body is installed on the On the support platform, the tip of the conical impactor is facing the outlet end of the fire extinguishing agent release hole.
优选的，所述圆锥撞击体的锥角为20-90度的恒定值或渐变值，撞击体的高度为0.3-2.0cm；所述灭火剂释放孔的孔径为3-5mm。Preferably, the cone angle of the conical impactor is a constant or gradual value of 20-90 degrees, the height of the impactor is 0.3-2.0cm; the diameter of the fire extinguishing agent release hole is 3-5mm.
应用本发明灭火时的应用过程如下：The application process when applying the present invention's fire extinguishing is as follows:
火灾探测模块首先感应到火灾信号，将该信号传导至灭火剂释放控制阀。然后，灭火剂释放控制阀组启动，将灭火剂容器中的低压灭火剂经撞击式雾化喷头撞击雾化喷出，实现高效、清洁、安全灭火。The fire detection module first senses the fire signal, and transmits the signal to the fire extinguishing agent release control valve. Then, the fire extinguishing agent release control valve group is activated, and the low-pressure fire extinguishing agent in the fire extinguishing agent container is atomized and sprayed through the impact atomizing nozzle to realize efficient, clean and safe fire extinguishing.
与现有技术相比，本发明的优点在于：Compared with the prior art, the present invention has the advantages of:
1、本发明的电力小微空间用灭火系统，采用撞击式雾化喷头以及储存压力低的环保清洁型灭火剂，撞击式雾化喷头可以增大灭火剂的蒸发表面积，实现在较低压力下将灭火剂雾化气化灭火，同时也可使得容器中的灭火剂存储压力处于较低的状态，使本发明同时具有灭火效率高、安全性高、结构简单、操作简便等优点。1. The fire extinguishing system for electric small and micro spaces of the present invention adopts an impact atomizing nozzle and an environmentally friendly and clean fire extinguishing agent with low storage pressure. The impact atomizing nozzle can increase the evaporation surface area of the fire extinguishing agent and realize the fire extinguishing agent under lower pressure.
