铅塔 meaning in English
lead column
Examples
- During the course of rectifying zinc , the fluid of coarse liquid zinc put into pb column from furnace works as a key technical parameter
在锌的精馏过程中，液态粗锌从熔化炉加入到铅塔这个过程的流量是一个关键的技术参数。 - ( 3 ) the result of imitating shows that the distribution of temperature look like triangle at present , the cause of temperature asymmetry is the mistake ratio of gas and air in the same vertical direction , the direction to improve on is by adjustment to distribute reasonably gas in different height and uniformly gas in same level
( 3 )仿真结果展现了目前铅塔燃烧室温度呈三角形分布，并揭示了造成这种不均匀分布的根本原因是空气、煤气在同一垂直方向的不匹配。并指出了改进方向是通过调整，使煤气2002年工程硕士毕业论文摘要在高度方向的名迢群引配、以及在水平方向均匀分布。 - In order to solve the problems effectively , under the auspices of 863 plan in china , the synthesis diagnosis has been carried by means of measuring and numerical imitating the combustion chamber of refining column , and some conclusions is such as : ( 1 ) through measuring the temperature and combustion in the burning chamber of the refining column , the result shows the temperature difference on the same level is more than that in height direction , and there is a few of co in bottom of burning chamber . ( 2 ) in order to ensure normal work of flue system in lead column in the course of zinc refining , theoretic calculation and measure about the flow resistance of exhaust gas are carried through . the results of study reveal that drawing out force of chimney is inadequate , which is mainly caused by illogicality of flue construction
在研究过程中，采取了现场实测和数值仿真手段对韶关冶炼厂锌精馏铅塔燃烧室及排烟系统进行了综合诊断，具体结果包括如下： ( 1 )完成锌精馏铅塔燃烧室内温度测试以及燃烧状况的测试，结果发现：铅塔燃烧室内水平方向的烟气温度并非均匀，而且其温差比上下方向的温差更大，以及铅塔燃烧室尾部存在co未燃烬问题； ( 2 )为了保证铅塔烟气系统的正常工作，对烟道系统的阻力进行了理论计算及测试分析，结果发现：锌精馏铅塔烟气系统中烟囱抽力不够，这主要是烟道结构不合理所造成的。
