Description

一种空气泡沫灭火枪 技术领域
本发明涉及消防灭火器具,特别涉及一种包括空气、泡沫灭火剂和水为灭火介质的空气泡沫灭火装置。
背景技术
在负压吸入空气泡沫灭火系统中,发泡倍数是系统灭火效能的重要指标,气液混合的充分程度关系到泡沫灭火剂的发泡倍数,而发泡后的混合液的喷射距离是系统灭火应用能力的重要性能指标。
现有泡沫灭火系统包括固定式或移动式灭火系统,无论固定式还是移动式泡沫灭火系统主要以液体泵为喷射动力,形成的泡沫灭火剂发泡倍数较低(3~8倍),覆盖和附着能力差,不适应现在多状态、较大火场的灭火需要。
泡沫灭火枪是移动式泡沫灭火系统的主要功能设备,混合液体介质通过提前预混合后通过灭火枪喷射。现有泡沫灭火枪的喷嘴结构多以轴向射流,并负压混合空气,形成的泡沫灭火剂发泡倍数较低(3~8倍),但还没有一种结构,可实现用低倍数泡沫液喷射并负压吸入空气方式,而达到发泡倍数为13~25倍。
发明内容
本发明根据现有技术的不足公开了一种空气泡沫灭火枪。本发明要解决的问题是提供一种可以将水、泡沫灭火剂、空气三者按灭火对象需求的 相应比例混合。液体介质通过流道呈多股交叉射流碰撞雾化后,产生引射力吸入空气,再混合的方式,实现用低倍数泡沫液达到发泡倍数为13~25倍的空气泡沫灭火枪。
本发明通过以下技术方案实现:
所述灭火枪为圆柱形中空结构,其特征在于:所述灭火枪包括设置于前端的空气泡沫混合液喷口;与混合液喷口在同一轴线、设置后端的空气入口;设置于空气入口轴线中心的灭火剂混合液入口和灭火剂混合液出口;设置于混合液喷口与空气入口结合部、均匀间隔环绕布置的水喷射斜口,水喷射斜口轴线与混合液喷口轴线夹角a为17~30度;水喷射斜口与结合部外壁的环形液体腔连通,环形液体腔有外供水源连通的水入口;灭火剂混合液入口与文丘里喷射器出口连通,文丘里喷射器吸入口通过比例调节阀与泡沫灭火剂贮存箱连通,在环形液体腔的水入口设置旁通水路与文丘里喷射器入口连通。
所述水喷射斜口环绕布置3~10个形成交叉射流。
所述水入口沿环形液体腔倾斜方向设置。
所述灭火剂混合液入口与旁通水路平行设置,旁通水路位于灭火剂混合液入口与灭火枪管壁连接部。
所述灭火剂混合液出口位于水喷射斜口后端。
所述环形液体腔位于混合液喷口与空气入口结合部外壁。
上述文丘里喷射器是利用文丘里原理制作的负压式吸入装置,有市售。
本发明为一种旁通文丘里管空气泡沫灭火枪。包括可以置于背架上可 移动的背负式灭火剂贮存箱、旁通文丘里喷射器、比例调节阀门、外供水源。空气入口与混合液喷口设置在同一轴向线上,空气入口与混合液喷口结合部是水喷射斜口,斜口形成的夹角a为17~30度,通常外供水压力0.8mpa时流量2L/S。空气泡沫灭火枪腔体铸造成型环形液体腔,外供灭火水入口沿环形液体腔切线方向设置。外供水源多种形式,满足压力0.2mpa~1.2mpa均可使用,即消火栓、手抬泵、消防车等供水压力都能正常运转。当外供水源供给,水流通过旁通水路流向文丘里喷射器,形成负压通过比例调节阀门吸取定比例的灭火剂,再通过出流喷头将灭火剂喷射与外供水源斜口喷射a处交汇撞击,形成极大的负压,从泡沫枪后端吸入大量空气,使得水、泡沫灭火剂、空气三者按相应比例混合,喷射出13~25倍的空气泡沫。
本发明空气泡沫枪,采用液体出口具有一定斜度的斜槽喷口交叉喷射,碰撞并雾化,既能产生比直流喷射泡沫枪更大的负压,吸入更多的空气,又因液体雾化增加与空气接触面积,产生更高的发泡倍数。其中泡沫混合液比例可调(0.1%~10%)、入口空气量可调节,从而调节泡沫干湿度。混合比例调节装置结构更简洁,操作方便,降低系统设备成本。

图1是本发明灭火枪结构横截面示意图;本发明灭火枪为圆柱形空管结构,空管前端为混合液喷口11,后端为空气入口12,中部为混合腔,中部包括设置于空管壁、环绕布置的水喷射斜口10,如图所示,本例水喷射斜口10为6个,均匀间隔布置,水喷射斜口10轴线与混合液喷口11轴线夹角a为17~30度,各水喷射斜口10入口端与环形液体腔9连通,入口端均衡的水压使各水喷射斜口10在混合腔在形成交叉射流碰撞并雾化,既能产生比直流喷射泡沫枪更大的负压,吸入更多的空气,又因液体雾化增加与空气接触面积,产生更高的发泡倍数。
