双套紊流正压浓相
1.
In operation,the MOLLER double turbulent positive dense ash-delivery system installed in Hejing Power Plant 2×350 MW generating-unit has encountered many breakdowns such as MOLLER valve breakdown,inclined groove blocking,ash-pipe stocking,ash delivery impeding,ash-sticking pan,leakage of pressed air pipe,ash delivery pipe blocking and so on.
在运行过程中,漳泽电力河津发电厂2×350MW机组MOLLER双套紊流正压浓相输灰系统曾出现了MOLLER阀故障、斜槽堵灰、灰管积灰、输灰不畅、灰斗落灰不畅、压缩空气管路泄漏、输灰管道堵塞等问题,采用多年现场事故处理经验相结合理论探讨的方法,分析了双套紊流正压浓相输灰系统故障产生的原因,找出了影响系统运行稳定性的主要因素,提出了改进措施和处理办法。
2)  turbulence double-pipe
紊流双套管
1.
Technology of turbulence double-pipe dense pneumatic conveying differs from other pneumatic conveying technology as its dry ash does not need to be suspended.
紊流双套管密相气力输送技术与其它气力输送技术明显不同是干灰不需要悬浮输送,因而其系统的设计、运行方式有其鲜明的特点:输送能力大,需要的输灰管道很少,输送速度低对系统的磨损轻。
3)  double-socket positive pressure dense phase ash disposal system
双套管正压浓相除灰系统
4)  barotropic dense-phase
正压浓相

6)  Squish turbulence
挤压紊流
补充资料:比浓渗透压
分子式:
CAS号:

性质: 溶液渗透压(π)与溶液浓度(c)的比值。渗透压是溶液依数性的一种,渗透压法可用于测定分子量2万以上聚合物的数均分子量及研究聚合物溶液中分子间相互作用情况。理想溶液的比浓渗透压可根据范特霍夫定律表示为。式中M是溶质的分子质量。对于非理想溶液:>。从实验结果可知,比浓渗透压π/c随c而变化,当,式中是聚合物的数均分子量;是无限稀释时,比浓渗透压服从范特霍夫定律,可当作理想溶液处理。
