inverse ventilation

Aiming at this problem, 3 methods of air supply were worked out, they are the methods of supplying air by assistant tunnel, by combination of drawing with blowing, and by backward air blowing.

针对这一问题 ,在新河和刘庄煤炭地下气化现场试验的基础上 ,研究了三种控制气流的方法 ,即辅助通道供风气化、压抽结合供风气化和反向供风气化 。

To reveal the pulsate dust-purging mechanism of plenum-type bag filter,the adiabatic energy equation based on aerodynamics is applied to the venting system,so as to drive theoretically the reverse air speed expression of bag filter surface in pulsate dust-purging process.

为了揭示气箱式脉冲喷吹袋式除尘器的清灰机理,应用空气热力学关于开口系统绝热能量方程,对气箱式脉冲袋式除尘器在脉冲喷吹过程中滤袋表面的反向风速数学表达式进行了理论推导。
