車用超細乾粉自動感應滅火裝置在煤礦車輛防自燃滅火上的發明應用

山東中道消防是國內較早從事研發定製車用超細乾粉自動滅火裝置的單位，該單位研發生產的礦用車輛防自燃自動滅火技術採用的是超細乾粉滅火劑，其裝置主要是由超細乾粉滅火劑控制箱、聲光報警裝置、K型感溫探頭探測裝置、異形啟動裝置、檢漏裝置以及防火管路等組成，當下在內蒙古、新疆、陝西、山東等地區應用比較多，下面簡單介紹下該裝置的應用特點。

Shandong Zhongdao fire protection is an earlier unit engaged in the research and development of customized automobile superfine dry powder automatic fire extinguishing device in China. The self ignition automatic fire extinguishing technology for mining vehicles developed and produced by the unit adopts ultra-fine dry powder fire extinguishing agent. The device mainly consists of ultra-fine dry powder extinguishing agent control box, sound and light alarm device, K-type temperature probe detection device, abnormal starting device, leakage detection device and fire prevention Pipeline and other components, currently in Inner Mongolia, Xinjiang, Shaanxi, Shandong and other regions are more widely used, the following is a brief introduction to the application characteristics of the device.

外貯壓式超細乾粉自動滅火系統（Automatic fire extinguishing system of superfine dry powder with external pressure storage）

外貯壓式超細乾粉自動滅火系統是將新型超細乾粉滅火劑和高壓氮氣分別貯存於不同的鋼瓶內，在需要滅火劑噴放時，高壓氮氣通過減壓閥進入貯存滅火劑的鋼瓶推動滅火劑噴放。

The external pressure storage type ultra-fine dry powder automatic fire extinguishing system stores the new-type superfine dry powder extinguishing agent and high-pressure nitrogen respectively in different steel cylinders. When the extinguishing agent needs to be sprayed, the high-pressure nitrogen enters into the cylinder storing the fire-extinguishing agent through the pressure reducing valve to promote the fire-extinguishing agent spraying.

在外貯壓式超細乾粉滅火系統中，滅火藥劑由於沒有氮氣加壓，高壓氮氣與超細乾粉滅火劑接觸時間很短，可以通過更小管道輸送更多的滅火劑。

In the external pressure storage water-based fire extinguishing system, the contact time between high-pressure nitrogen and water-based fire-extinguishing agent is very short due to the absence of nitrogen pressure, so more extinguishing agent can be transported through smaller pipelines.

In the superfine dry powder fire extinguishing system with external pressure storage, the contact time between high-pressure nitrogen and superfine dry powder extinguishing agent is very short due to the absence of nitrogen pressure, so more extinguishing agent can be transported through smaller pipelines.
