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.

對平衡催化劑篩分組成、再生煙氣粉塵含量、沉降器VQS效率計算、工藝操作參數等進行分析后,采用了提高沉降器料位,用料封代替旋分器翼閥翼板的密封作用的方法,解決了沉降器VQS催化劑跑損的問題。

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

對負壓差下立管 -翼閥系統的氣固流動特性進行了理論分析 ,并系統地考察了翼閥結構、操作條件、顆粒物性等對立管 -翼閥系統中氣固兩相流動的影響 ,得到了穩定操作狀態下料腿中料封高度的計算式。

The minimum aeration rate of the standpipe trickling valve system influenced by the structure of dipleg under negative differential pressure was investigated.

考察了引入松動氣對立管 -翼閥穩定操作的影響。

Analysis and Research on the Dynamic Pressure in the Diplegs of a Cyclone Separator With Trickle Valves;

帶翼閥旋風分離器料腿內動態壓力的分析研究

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

帶翼閥旋風分離器料腿內靜壓分布試驗研究

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.

影響料腿內壓力分布的主要因素是料腿兩端的壓差,而與翼閥的位置無關;料腿內的的料封高度與料腿兩端的壓差和翼閥的插入位置有關;顆粒質量流率對壓力分布影響明顯,料腿兩端的壓差影響較小。
