铁合金电炉烟尘治理技术分析

本文在分析了半封闭铁合金电炉产生的烟气、烟尘的特性和各种除尘设备性能的基础上，提出了净化铁合金电炉烟尘的三种技术：袋式除尘、强化湿式除尘和文丘里除尘器。并对袋式除尘工艺和Calvert洗涤器除尘工艺作了介绍，分析了它们的经济技术指标。半封闭铁合金电炉烟尘只能采用布袋除尘器净化，只有那些建在环境空气质量三类区的铁合金电炉，当资金非常紧缺时，才可采用Cavlert洗涤器除尘。

Numerical Simulation of Synoptic Condition on a Severe Sand Dust Storm

By using observational data and MM5, an observational analysisand numerical study was conducted on the synoptic condition of a severe dust storm that was caused by a Mongolian cyclone whichoccurred from 6 to 8 April 2001. Results illustrated thatthe cyclogenesis was due to the isentropic potential vorticity (IPV) advection in the upper troposphere and the terrain modifiedbaroclinicity in the mid-lower troposphere. The Altai-Sayan complex of mountains blocked the lower level cold air and made the isentropic surface sharply steep. When the air slid down along the isentropic surface the increasing of baroclinicity anddecreasing of stability blew up the vertical vorticity development.The formation of the dust storm was a result of a cyclonic cold front passing across the area. The occurrence of this dust stormwas closely related to the strong surface wind, which was accompanied by a cold front passing, rather than the cyclogenesis, itself. Hence, the reason for the pre-front dust storm formulation was the formation of heating convection. Reasons behind the formation of a black storm (visibilitylower than 50 m), which occurred in the mid-north part ofInner Mongolia, lay in several aspects. Firstly, in thisarea the surface wind was strong, a direct result of thedownward transport in mid-lower troposphere. Secondly,the cold front passed over the effected area near sunsetso the air obtained much more surface heating to form adeeper mixed layer (ML). Thirdly, cooperation between thelower level wind and the terrain made the atmosphere inthis area and acquired the maximum advective contributionnecessary to form a deep post-front ML. The sensitivityexperiment revealed that surface heat flux was important to the frontal lifting. In addition, the forcing of surface heating wasalso seen as the primary forcing mechanism of frontogenesis. Meanwhile, removal of the surface heat flux made the atmosphericstratification became stable and the pre-storm ML very shallow,which weakened the strength of the dust storm.

半敞开烟气排放的测试方法的研究

综合分析了除尘系统进入的烟尘量、排放方式、排放浓度等5个参数及其相互关系,根据在一定时间内进入除尘系统烟气烟尘的量;对除尘器进口和出口即百叶窗内各方向烟尘浓度的测试,利用物料平衡方程,确定百叶窗内各测点各方向测定的烟气烟尘浓度,确定半敞开排放烟气烟尘的排放浓度,笔者发现,外排烟尘浓度与百叶窗内侧向烟尘浓度具有良好的线性关系,百叶窗内侧向测定烟尘浓度能够反映半敞开烟气排放浓度。据此,提出以半敞开方式排放烟气烟尘的除尘系统烟气烟尘浓度测试方法,即侧向间接测试法。
