The invention discloses a cyclone type arrester, comprising a fire resistant sheet and a shell body; fire resistance including were banded smooth belt and fire belt, fire retardant belts are pressed on along the length direction of strip shape are arranged in oblique corrugated shape, inclined corrugated inclined fire belt length to set, smooth with folded and coiled disk like structure and fire resistance; fire resistance sheet is arranged on the shell body. In this way, through the fire resistance belt pressing strip of corrugated shape, the inclined corrugated inclined length in the direction of the fire with a set of such fire resistance with air channel formation and smooth zone between the parallel axis and fire resistance sheet or not coplanar, which makes the flow channel and the direction of the flow of air blast is not the same, and the formation of the surface exposed to a fire, explosion in the direction of flow, high temperature and high speed airflow generated high rate impact on the side exposed to fire the energy fast decay, backfire surface can effectively resist the impact of high rate, greatly improve the anti fire and anti explosion effect.

,具体涉及一种阻火器。
技术介绍
阻火器是用来阻止易燃气体、液体的火焰蔓延和防止回火而引起爆炸的安全装置,通常装在输送或排放易燃易爆气体的储罐和管线上。阻火器是应用火焰通过阻火片(层)的狭小孔隙时,由于热量损失而熄灭的原理设计制造。阻火器的阻火片(层)结构有砾石型、金属丝网型或波纹型。大功率防爆柴油机要达到ⅡB、ⅡC的安全防爆性能,其进气阻火器必须具备阻止氢气或乙炔等气体等被引爆后产生高爆炸压力引起的冲击传爆。目前,现有技术制造的防爆波纹阻火器中的阻火片200呈圆盘结构,其上形成有若干三角通道,三角通道与圆盘状结构的轴向方向平行,爆炸时,爆炸气流穿过三角通道,通过热传导降温、破坏大量链式反应。但由于三角通道与圆盘状结构的轴向方向平行,这样爆炸气流流通的方向就会与三角通道一致,构成直线传导,阻火性能较差。因此为了提高阻火性能及阻火片200的易加工,阻火器100通常采用多片阻火片200的组合,而且多组阻火片200是相互紧靠安装(如图1所示)。大功率防爆柴油机由于多气缸及气缸的容积较大而充气量多,其内部结构形成多个内腔与弯道 ...
