Description

一种无电非储压式灭火***Non-electricity and non-pressure storage type fire extinguishing system 技术领域Technical field
本发明属于消防领域，特别涉及一种无电非储压式自动灭火***。The invention belongs to the field of fire protection, and particularly relates to a non-electricity and non-pressure storage type automatic fire extinguishing system.
背景技术Background technique
消防领域现存灭火***的反馈环节多需要供电支持，如紫外、红外、烟雾传感器等，灭火介质多采用采用储压式灭火剂瓶储藏，如七氟丙烷气瓶、惰性气体气瓶等，但通过大量应用案例暴露出了现存灭火***的一些问题，例如：The feedback link of the existing fire extinguishing system in the fire protection field requires power supply support, such as ultraviolet, infrared, smoke sensors, etc. The fire extinguishing medium is mostly stored in storage pressure extinguishing agent bottles, such as heptafluoropropane gas cylinders, inert gas cylinders, etc., but through a large number of applications The case exposed some problems with the existing fire extinguishing system, such as:
(1)电反馈***在因火灾先烧毁供电设施而断电的情况下失效。(1) The electrical feedback system fails when the power supply facilities are burned down due to a fire and the power is cut off.
(2)七氟丙烷灭火***的七氟丙烷瓶在长期储存时存在压力降低的情况，5年左右需检修维护，高压气瓶本身就是危险源。(2) The pressure of the heptafluoropropane cylinders of the heptafluoropropane fire extinguishing system will drop during long-term storage, and maintenance is required for about 5 years. The high-pressure gas cylinders themselves are the source of danger.
(3)使用内置式或外置式二氧化碳气瓶作为灭火剂喷出动力源的灭火***存在冬季低温条件下因相变无法工作的情况，不适合在野外低温环境中使用。(3) The fire extinguishing system that uses built-in or external carbon dioxide gas cylinders as the power source for the fire extinguishing agent is unable to work due to phase change under low temperature conditions in winter, and is not suitable for use in low-temperature outdoor environments.
(4)地下停车场内使用的感温玻璃泡启动的喷雾管网***存在管路内压力不足或漏水的问题。(4) The spray pipe network system activated by the temperature-sensitive glass bubble used in the underground parking lot has the problem of insufficient pressure or water leakage in the pipeline.
(5)采用伍德合金等易熔合金作为感温元件，同时采用弹簧拉线式启动方式启动灭火器的灭火***，如厨房自动灭火***，存在火灾响应慢的问题，此外，因弹簧弹力限制、拉线长度限制，致使感温元件和灭火剂储罐无法相距太远，导致灭火***覆盖面十分有限。(5)Using fusible alloys such as Wood's alloy as the temperature sensing element, and adopting the spring pull wire start method to start the fire extinguishing system of the fire extinguisher, such as the automatic fire extinguishing system in the kitchen, which has the problem of slow fire response. In addition, due to the spring elasticity limitation and the length of the wire Due to restrictions, the temperature sensing element and the fire extinguishing agent storage tank cannot be too far apart, resulting in a very limited coverage of the fire extinguishing system.
发明内容Summary of the invention
针对现有技术的不足，本发明提供一种无电非储压式灭火***，它摆脱供电约束和反馈信号传输距离长的技术缺陷，能在野外低温环境中使用、且可以长期免维护，能广泛用于仓库、电力设备、舰船、工程车辆等的灭火。In view of the shortcomings of the prior art, the present invention provides a non-electricity and non-pressure-storage fire extinguishing system, which gets rid of the technical defects of power supply constraints and long feedback signal transmission distance, can be used in a low temperature environment in the field, and can be long-term maintenance-free. It is widely used for fire extinguishing in warehouses, power equipment, ships, engineering vehicles, etc.

(2)气动管路有效传输距离长，可以根据需要，方便弯折且不影响动力气体传输。150m长内径为4mm不锈钢管路仅需在感温气源端有5g气体发生药剂(发气量400L/kg)工作的情况下，便能顺利启动管路另一端的气动启动器。(2) The pneumatic pipeline has a long effective transmission distance, which can be easily bent as required without affecting the transmission of power gas. The 150m long stainless steel pipe with an inner diameter of 4mm only needs to work with 5g gas generating agent (400L/kg) at the end of the temperature-sensing gas source, and the pneumatic starter at the other end of the pipe can be started smoothly.
(3)免维护期长。由于感温气源和灭火剂储罐气体发生器内的复合固体推进剂使用寿命均可达到10年以上。罐体为非储压式，且整个***未预先加压，正常情况下长期储存基本不存在灭火剂泄露的可能。(3) Long maintenance-free period. The service life of the composite solid propellant in the temperature-sensitive gas source and the gas generator of the fire extinguishing agent storage tank can reach more than 10 years. The tank is of non-pressure storage type, and the entire system is not pre-pressurized. Under normal circumstances, there is basically no possibility of extinguishing agent leakage in long-term storage.
(4)可在野外低温环境中使用。采用特定耐低温型复合固体推进剂药剂和耐低温型灭火剂可使该***在-40℃野外环境中使用。(4) It can be used in low temperature environment in the field. The use of specific low-temperature-resistant composite solid propellant agents and low-temperature-resistant fire extinguishing agents enables the system to be used in a field environment at -40°C.
