高倍數泡沫發生器是高倍數泡沫滅火機的主要設備之一。既可用于固定滅火設備,也可用于移動滅火設備,其優點是發泡量大,適合于小空間全淹沒式滅火。那么,高倍數的泡沫發生器是如何滅火的?通常安裝在哪里?下面
川消小編為您分析:
High expansion foam generator is one of the main equipment of high expansion foam fire extinguisher. It can be used for both fixed fire extinguishing equipment and mobile fire extinguishing equipment, with the advantage of high foaming capacity and suitable for fully submerged fire extinguishing in small spaces. So, how does the high expansion foam generator extinguish the fire? Where is it usually installed? Below, the editor of Chuanxiao will analyze for you:
以0.3-1.0MPa壓力泡沫混合液為動力,推動水輪轉動,混合物通過噴頭將其混合液噴入發泡網絡,使其內表面形成一層薄膜,由風輪將其吹入網線,將膨脹吹塑成高倍數的泡沫,以淹沒或覆蓋燃燒物表面。通過對泡沫的遮蓋、冷卻及窒息作用來滅火。高倍數泡沫滅火系統在全淹沒和局部使用時,固定在保護區域內,以實現滅火。
Powered by the 0.3-1.0MPa pressure foam mixture, the water wheel is driven to rotate. The mixture is sprayed into the foam network through the nozzle to form a film on its internal surface, which is blown into the wire by the wind turbine to form a high expansion foam to submerge or cover the surface of combustibles. Extinguish fire by covering, cooling and suffocating foam. When the high expansion foam fire extinguishing system is totally submerged or partially used, it is fixed in the protected area to extinguish the fire.
高倍數的泡沫層能封住燃燒物表面,能遮住火焰對燃燒物的熱輻射,阻止燃燒物的蒸發或熱解揮發,使可燃氣體不易進入燃燒物表面,高倍數的泡沫覆蓋層能將燃燒物表面與空氣隔離。大量大量的泡沫沉淀液,其表面起著冷卻作用。高倍數泡沫蒸發產生的蒸汽具有稀釋燃燒區氧濃度的作用。
The high expansion foam layer can seal the surface of the combustor, block the thermal radiation of the flame on the combustor, prevent the evaporation or pyrolysis volatilization of the combustor, make it difficult for the combustible gas to enter the surface of the combustor, and the high expansion foam cover layer can isolate the surface of the combustor from the air. A large amount of foam precipitate, whose surface plays a cooling role. The vapor generated by the evaporation of high expansion foam can dilute the oxygen concentration in the combustion zone.
高倍數泡沫發生器是固定裝在建筑物內,墻壁與泵站之間用管道連接的給水發泡滅火。
The high expansion foam generator is fixed in the building, and the water supply foam fire extinguishing is connected between the wall and the pump station with pipes.
(1)距離泡沫發生器空氣入口端300cm以內不應有遮擋物。
(1) There should be no obstructions within 300cm from the air inlet end of the foam generator.
(2)在泡沫發生器的發泡網前進1m范圍內,不應設置妨礙泡沫噴射的障礙。
(2) Within 1m ahead of the foam mesh of the foam generator, there should be no obstacles preventing foam spraying.
(3)使用于全沉式系統的泡沫發生器,其安裝高度應高于泡沫設計到達的高度。
(3) The installation height of the foam generator used in the fully submerged system should be higher than the height reached by the foam design.
(4)泡沫網面向保護區。
(4) The foam net faces the protected area.
This is the end of the fire extinguishing process of the high expansion foam generator and related matters of the installation site. I hope I can give you good help. If there is anything else, please come to our website http://www.xintli.net consulting service
