双级关风器锁气性能试验研究

The Experimental Study on Locking Performance of Double-step Air-locker

提出了外加锁闭气的双级关风器锁气系统,对双级关风器的锁气性能进行了试验研究,测得了不同锁闭气体流量下的仓压,拟合得到了理论最大仓压与锁闭气体流量之间的经验关系式。试验结果表明:双级关风器锁气系统能够实现仓内气体的完全锁闭,为化工过程特殊气体的锁闭提供了一种简单有效的方法。

The double-step air-locking system plus with locking gas was proposed.The locking performance of double-step air-locker was studied experimentally.By measuring the silo pressure under different flow rate of locking gas, the empirical relation between the theoretical maximal pressure and the flow rate of locking air was developed .The experimental results showed that the silo gas could be completely locked by double -step air-locker and provide a simple and effective method for locking special gases in the process.
