Two disadvantages exist in the direct-fire type dryer for particles in particleboard factories at home today, namely, the possible pollution by the unburned coal dust and the accidental fire that may occur in particles in the rotary drum. In order to raise its efficiency, some improvements have been made in four respects:

目前,国内刨花板工厂或车间使用的烟气加热刨花干燥机存在着两个缺点,即在操作过程中,未完全燃烧或带有明火的炭粒可能会污染刨花和引起失火。为了改进其性能,我们进行了四方面的试验: 1.在烟气发生炉内增设了一道挡火墙,显著改善了刨花污染程度,并避免了刨花与明火的直接接触, 2.分段制造干燥转筒,减少了中小型刨花板工厂在制造,安装和维修干燥机方面的困难; 3.干燥机使用了司·控硅无级调速,干燥转筒的转速可以在2—16(r.p.m)范围内调节; 4.增设了简易防火装置,保证干燥转筒内烟气温度始终低于刨花着火点。 这种经过改进的新型烟气加热刨花干燥机已经使用二年多时间,效率和性能都比旧式烟气加热刨花干燥机好。

A method was adopted for studying permethrin residues in radish plants,in which the insecticide was extracted with acetone and partitioned intopetroleum ether; the extract was purified on a column containing silica geland activated charcoal; analysis was conducted by gas-liquid chromatographywith an electron-capture. The results indicate that, in field-conditions,the permethrin in radish plants is stable. The rates of their loss anddegradation are slow. Its half-life (HL_(50)) is abont 4.5 days. Permethrinhardly moves from the application site to other parts of the plant. Afterapplication of the insecticide, the radish tuber contains only a small resi-due and most of pollution occurs in the leaves. Spraying on the leaf atthe does of 5g permethrin/mu, the residue in radish tubers is below 0.03mg/kg. Rain has some influence upon the residue of the insecticide. Howe-ver, it is not prominent. There isn't a significant difference betweenthe cis-and trans-isosomers on the rates of their loss and degradation.

本试验用丙酮提取,石油醚液-液分配,经硅胶-活性炭混合柱纯化,气相色谱电子捕获测定,研究了二氯苯醚菊酯在萝卜植株上的残留消解动态。试验结果表明,在田间自然环境下,二氯笨醚菊酯在萝卜植株上较稳定,降解消失较慢,半表期约4.5天。它对植物组织的穿透力弱,在萝卜肉质根里的残留量低。主要污染部位在萝卜叶,使用有效成分5克/亩的剂量叶面喷雾,萝卜肉质根里的残留量低于0.03ppm,消解分为两个阶段,前一阶段较快,后一阶段较慢。降雨对药剂的残留消解有一定的影响,但不明显。顺、反两种异构体的消解速率差异不大。

The purpose of this paper is to recommend the development of SFF-40 hot-blast stove burning coal. At first, the process of energy consumption is analyzed and then the way of M751 heat-stter is recommended to operate with SFF-40 hot-blast stove. According to the measurements carried out by us, it may be concluded that the hot-blast stove has better economic result, and also the advantages of energy-saving, more safety and less pollution.
