Q:你们的药品柜能控温吗?A:不能,控温就不能室内循环了,我们的柜子设计了专门的进风出风口,保证通风能力。对于控温型净气型药品柜,我司也正在研发当中。Q:你们的柜子材质是什么,防腐蚀吗?A:金属部分为1.2mm镀锌钢板,涂有抗腐蚀涂层,抗腐蚀能力强;过滤器采用聚丙烯(PP)框体,抗腐蚀能力强。Q:大量的化学品操作能用吗?A:一般情况下,几乎99%以上的化学实验室使用我司净气型药品柜是没有任何问题的,但对于通风柜,由于过滤器的吸附量一定,如果是大量的操作,过滤器的寿命会相应减少,所以需要填写问卷,我司实验室判定过滤器大致寿命,有些操作可结合我司研发的新技术(如冷凝回收装置等)与通风柜有机结合,保证过滤器寿命达到一定程度。
不锈钢反应釜以其优良的耐腐蚀性能和较低的价格,赢得越来越多客户的喜爱和信赖;因此在搅拌与反应釜结合处的密封的选择对于密封效果、使用安全、节约成本等都显得特别重要,现对如何选择合适的密封形式做出如下建议:1.首先要明确密封选择的依据:是釜内的工作压力,第二是工作物料的性质。还有一个就是设备的工作温度。其次要明确不锈钢反应釜所用密封的类别:反应釜所用密封即通常所说的轴封有两类,是填料密封,第二是机械密封,机械密封又分为单机封(即单端面机械密封)和双机封(即双端面机械密封),单机封全套还包括水夹套,双机封则较为复杂,除水夹套(必须有循环冷却水)外,还包括配套的支架、平衡罐等。如何选择合适的密封:在常温常压,物料没有挥发性也不易燃易爆的使用条件下,要选择填料密封;在压力小于4公斤,物料的易挥发性和易燃易爆性一般的使用条件下,就要选择单机封;在工作压力超过4公斤(但要小于1公斤),物料的易挥发性和易燃易爆性很强的使用条件下,则必须选择双机封。各种密封的优缺点:填料密封价格便宜,但只适合普通的使用条件和物料;单机封价格适中,可以在大多数使用条件下通用;双机封价格贵,但在苛刻的工作条件下必须使用。
5T/万立方米影响脱硫因素。煤气中的焦油雾滴小于1MG/M3为宜。与碱形成疏水性膜,碱液颜色变暗,使碱液吸收效果变差,会使溶液中的催化剂活性降低,硫就显褐色。硫磺变茶褐色,甚至上浮一层油。氨与硫化氢平衡分压较高,协手进入碱液,会降低深液碱度,破坏碱液PH值平衡,同时与焦油雾一起造成碱液雾化,硫泡沫浮选困难。脱硫温度大于4度主宜。。-。碱度为宜。溶液再生时间。
下面给大家介绍脉冲袋式除尘器结露的原因:一般,脉冲袋式除尘器结露的原因是外壳常常会有空气漏入,导致脉冲袋式除尘器室内气体温度低于露点,除尘滤袋就会受潮,致使灰尘不是松散地,而是粘糊地附着在滤袋上,把织物孔眼堵死,造成清灰失效,使脉冲袋式除尘器压降过大,无法继续运行,有的产生糊袋无法除尘。当脉冲袋式除尘器发生结露现象时的解决方法:做好脉冲袋式除尘器管道等有关各处的保温与防雨。实践证明良好的保温措施,可使除尘器进、出口温度相差很小,这是防止结露的一项有效措施。
