Description
技术领域：Technical field:
本实用新型涉及一种煤矿用防、灭火系统，特别是使用低温惰性液体、低温惰性气体给煤矿灭火的系统。The utility model relates to a fire prevention and extinguishing system for coal mines, in particular to a system for extinguishing fires in coal mines by using low-temperature inert liquid and low-temperature inert gas.
背景技术：Background technique:
在煤矿开采中，由瓦斯气体引起的着火事故时有发生，给国家资源和人民生命财产造成巨大损失。目前煤矿灭火时多数是采用向矿井内直接注入惰性液体的方法，这种方法的缺点是由于惰性液体和惰性气体之间的气化比在1∶600以上，惰性液体在火区内突然膨胀，容易将火区内的瓦斯气体和氧气推向发火区域引起爆炸，从而造成更大的损失。In coal mining, fire accidents caused by gas occur frequently, causing huge losses to national resources and people's lives and property. At present, when coal mines are extinguished, most of them use the method of directly injecting inert liquid into the mine. The disadvantage of this method is that because the gasification ratio between the inert liquid and the inert gas is above 1:600, the inert liquid suddenly expands in the fire zone. It is easy to push the gas and oxygen in the fire area to the fire area to cause an explosion, resulting in greater losses.
发明内容：Invention content:
本实用新型所要解决的技术问题是提供一种低温惰液、惰气防、灭火系统，利用该系统给煤矿灭火，能避免因直接向火区内注入惰性液体，将火区的瓦斯气体和氧气推向发火区域而引起的爆炸，从而减少损失。The technical problem to be solved by the utility model is to provide a low-temperature inert liquid and inert gas fire prevention and fire extinguishing system. Using this system to put out fires in coal mines can avoid directly injecting inert liquids into the fire area, causing the gas and oxygen in the fire area to be extinguished. The explosion caused by pushing to the ignition area, thereby reducing the loss.
上述目的是这样实现的：它包括低温惰液储罐、空气加热式汽化器和气体减压器，空气加热式汽化器包括星型管和框架，星型管装在框架上；低温惰液储罐外面罩有保护壳，保护壳内壁与低温惰液储罐之间填充有保温材料，低温惰液储罐上有液位计、压力表、安全阀及回气增压管道和进、出液管道，进、出液管道外端连接有第一三通，三通的垂直接口有分支管道与传输泵的入口相连，分支管道上装有阀门，传输泵的出口与液体输送管道相连，液体输送管道供与煤矿中的灭火输送管道相连；进、出液管道外端连接的三通的另一个水平接口与空气加热式汽化器的星型管的入口连接，星型管的出口处连接有第二三通，三通的另一个水平接口通过管道与气体减压器的入口相连，气体减压器的出口供与煤矿中的灭火输送管道相连；低温惰液储罐上的回气增压管道的端部与空气加热式汽化器的星型管出口处的三通的垂直接口相连，回气增压管道上有阀门。The above-mentioned purpose is achieved in this way: it includes a low-temperature inert liquid storage tank, an air-heated vaporizer and a gas pressure reducer, the air-heated vaporizer includes a star-shaped tube and a frame, and the star-shaped tube is mounted on the frame; The mask has a protective shell, and insulation materials are filled between the inner wall of the protective shell and the low-temperature inert liquid storage tank. There are liquid level gauges, pressure gauges, safety valves, return air booster pipes, and liquid inlet and outlet pipes on the low-temperature inert liquid storage tank. The outer ends of the inlet and outlet pipes are connected with the first tee, and the vertical interface of the tee is connected with the inlet of the transfer pump by a branch pipe. The branch pipe is equipped with a valve, and the outlet of the transfer pump is connected with the liquid delivery pipeline. The liquid delivery pipeline is supplied to the coal mine The other horizontal interface of the tee connected to the outer end of the inlet and outlet pipes is connected to the inlet of the star-shaped tube of the air-heated vaporizer, and the outlet of the star-shaped tube is connected to the second three-way, three The other horizontal interface of the gas pressure reducer is connected to the inlet of the gas pressure reducer through a pipeline, and the outlet of the gas pressure reducer is connected to the fire extinguishing pipeline in the coal mine; the end of the return gas booster pipeline on the low temperature inert liquid storage tank is heated with air The three-way vertical interface at the outlet of the star tube of the type carburetor is connected, and there is a valve on the return air booster pipeline.
工作原理及优点：先将低温惰液储罐内的部分低温惰性液体转换成气体，方法是关闭回气增压管道上的阀门和分支管道上的阀门，将气体减压器与煤矿中的灭火输送管道连通，低温惰液储罐内的低温惰性液体在空气加热式汽化器内转换为惰性气体，然后经气体减压器输送到火区内。待火 区内的瓦斯和氧气指标达标后，开启回气增压管道上的阀门和分支管道上的阀门，关闭气体减压器，将惰性液体输送管道与煤矿矿井中的灭火输送管道连通，低温惰性液体经管道传输泵直接输送到火区内，使得低温惰性液体在火区内迅速膨胀，降温，实现灭火的目的。优点是由于设置了管道传输泵，可实现远距离输送，能保证灭火时人员及其它设备的安全；又由于设置了回气增压管道，低温惰性液体在空气加热式汽化器内转换为气体后回到低温惰液储罐内，可防止在释放低温惰性液体过程中，因为压力降低使低温惰性液体形成固态堵塞管路的问题；所以利用该系统给煤矿灭火，能避免因直接向火区内注入惰性液体，将火区的瓦斯气体和氧气推向发火区域而引起的爆炸；另外本系统结构简单，灭火效果好，操作安全可靠。Working principle and advantages: first convert part of the low-temperature inert liquid in the low-temperature inert liquid storage tank into gas by closing the valve on the return air pressurization pipeline and the valve on the branch pipeline, and connecting the gas pressure reducer with the fire extinguisher in the coal mine The delivery pipeline is connected, and the low-temperature inert liquid in the low-temperature inert liquid storage tank is converted into inert gas in the air-heated vaporizer, and then transported to the fire zone through the gas pressure reducer. After the gas and oxygen indicators in the fire zone reach the standard, open the valves on the return gas pressurization pipeline and the valves on the branch pipelines, close the gas pressure reducer, and connect the inert liquid pipeline with the fire extinguishing pipeline in the coal mine. The inert liquid is directly transported to the fire area through the pipeline transmission pump, so that the low-temperature inert liquid expands rapidly in the fire area, cools down, and realizes the purpose of fire extinguishing. The advantage is that due to the installation of a pipeline transmission pump, long-distance transportation can be realized, and the safety of personnel and other equipment can be guaranteed during fire extinguishing; and due to the installation of a return air booster pipeline, the low-temperature inert liquid is converted into gas in the air-heated vaporizer and then returned to the air. In the process of releasing the low-temperature inert liquid, it can prevent the problem that the low-temperature inert liquid forms a solid blockage due to the pressure drop during the release of the low-temperature inert liquid; The inert liquid pushes the gas and oxygen in the fire area to the fire area to cause an explosion; in addition, the system has a simple structure, good fire extinguishing effect, and safe and reliable operation.
