 本发明的实施方式
如图1-4所示，本实施例提供一种组装式紊流火焰装置：其包括气箱1及设在其内的4个组合板，每个组合板由隔板2和弧形板3组成，并且隔板2的一侧与弧形板3固定连接而另一侧与气箱1的内壁固定连接，四个隔板2与四个弧形板3均关于气箱1的中心轴线呈等角度分布，以中心对称方式将气箱1的内部分为四个气体区间；气箱1的顶部和底部分别固定连接有顶板4和底板5，底板5沿四周均开设有通气孔11，四个通气孔11分别与所述四个气体区间的内部连通。气箱1的内部活动连接有转筒6，顶板4的内部开设有与转筒6相适配的活动孔7，底板5的顶部开设有与转筒6相适配的环形槽12，转筒6可穿过活动孔7进入气箱1并与环形槽12的内部活动连接，转筒6的上端为圆筒，转筒6周面相对的两侧且位于圆筒的下方开设有通槽。两个组合板相接处为进风口，实验完成时，进风口可用挡板封闭以免惰性气体等气体灭火剂扩散到大气中去；挡板8插在隔板2与相对的弧形板3之间，连接方式为滑动连接，顶板4的内部开设有与挡板8相适配的通孔9，并且底板5开设有与挡板8相适配的滑槽10；挡板8于气箱1内设置有两个，通孔9、滑槽10亦开设有两个。气箱1的外部表现形状为密闭的圆筒，并且气箱1采用透明玻璃制成，气箱1的高度为0.54m，并且挡板8和转筒6的高度均为0.56m，顶板4与底板5的厚度均为0.005m。
使用方式一：点燃燃料，将燃料放入气箱1底部中心，燃料在底板5的顶部进行燃烧，输气管道通过四个通气孔11向气箱1的内部输入空气或氧气，由于气箱1内的燃料燃烧迅速消耗掉装置内氧气，同时空气被加热而向上运动，使得燃烧体内压强减少，形成的压强差迫使气体区间内的气体进入燃烧体内,由于气箱1内部的弧形圆壁设计使得进入的气体迅速形成一个围绕火源的横向切向环流，从而产生湍流火焰。可以一并在气箱1外部安装观测系统、热电偶系统等进行常规紊流火焰的观测实验，由于实验在密闭环境空间内，通过气箱1体积的计算、输气管道对输入气体流量的控制，可定量的测得通入气体的体积。
使用方式二：从气箱1上部、活动孔7插入转筒6，转筒6的底端与环形槽12接触，转动转筒6，转筒6在转动的过程中会存在一对侧气体通入燃烧区域，一对侧气体被阻隔。输气管道通过四个通气孔11分别在两个相对气体区间A输入助燃性气体氧气或空气，对另两个相对的气体区间B输入惰性气体或卤代烃灭火剂等组成的混合气体，点燃燃料，将燃料放入气箱1底部中心，燃料在底板5进行燃烧，缓慢转动转筒6，使2个助燃性气体区间A与燃烧区间相通，使2个气体灭火剂区间B与燃烧区间相阻隔，压强差迫使气体区间A内的气体进入燃烧区间内,由于气箱1内部的弧形圆壁设计使得进入的气体迅速形成一个围绕火源的环流，从而产生湍流火焰。待火焰稳定后，缓慢转动转筒6，使2个气体区间A与燃烧区间相阻隔，使2个气体灭火剂区间B与燃烧区间相通，就可以在压强差的作用下，使气体灭火剂进入燃烧区间，在外部即可动态观察惰性气体以及卤代烃气体等灭火剂对湍流火焰的作用及影响。
方式一和方式二的实验后，停止输气管道的气体供应，旋转转筒6至一定角度并插入挡板8，即可完全封闭气箱1内的气体，防止其扩散到大气中去。
