wing valve

After analysing equilibrium catalyst sieve composition, powder content of regenerative flue gas, VQS efficiency calculation of settler and process operating parameters, the problem of catalyst loss in settler VQS was solved by rising feed position in settler and replacing seal of wing valve with feed.

对平衡催化剂筛分组成、再生烟气粉尘含量、沉降器VQS效率计算、工艺操作参数等进行分析后,采用了提高沉降器料位,用料封代替旋分器翼阀翼板的密封作用的方法,解决了沉降器VQS催化剂跑损的问题。

The flow characteristics of standpipe trickling valve system under negative differential pressure was theoretically analyzed and experimentally studied.

An Experimental Study on the Pressure Distribution in the Diplegs of a Cyclone Separator With Trickle Valves;

带翼阀旋风分离器料腿内静压分布试验研究

Analysis on experimental data,it is concluded that the fluid regimes in the standpipe are consisted of entrance rotary segment,lean phase segment and dense phase segment,and the pressure distribution of the standpipe is relative to the pressure drop of the standpipe and independent of the position of the trickle valve,and the height of the dense phase.

影响料腿内压力分布的主要因素是料腿两端的压差,而与翼阀的位置无关;料腿内的的料封高度与料腿两端的压差和翼阀的插入位置有关;颗粒质量流率对压力分布影响明显,料腿两端的压差影响较小。
