锅炉除尘器外壳的重要性

文章作者:admin发布时间:2016-05-10 17:31浏览次数:


锅炉除尘器使用效果好坏和它的外壳设计也有重要关系。从材料本身来看,现在已经可以达到很高的效率,但是,往往由于锅炉除尘器外壳设计不良,或者除尘器的布置、安装存在缺点,以致灰尘不经过滤介质而旁通过去,造成不好的后果。
The use effect of the boiler dust collector and its shell design also has important relations. From the point of view of the material itself, now you can achieve very high efficiency, however, often because of poor design of the boiler precipitator shell, or dust collector arrangement, installation has some shortcomings, so that dust without filter media and bypass the past, resulting in bad consequences.
关于外壳设计的基本要求,有这样一些:
Basic requirements on the shell design, there are such a number of:
(1)把锅炉除尘器装在外壳内,应当让气流通过过滤器的方向倾向于把过滤器向密封面压紧。如果不能这样做,就必须采取适当办法把过滤器对着它的密封面夹紧,保证任何时候都不会松开。
(1) the boiler dust collector is installed in the housing, should let the air flow through the filter in the direction of the filter to the sealing surface. If you can not do so, you must take the appropriate approach to the filter facing its sealing surface, to ensure that no time will be released.
(2)如果气流是垂直经装在外壳内的过滤器,通常应使空气从上向下流动,因为这样可以防止过滤器捕集的污染物在进行维修等工作时失落。
(2) if the air flow is a vertical filter installed in the enclosure, the air is normally to be made to flow downward from the air, as this prevents the filter from being lost when it is being repaired.
(3)外壳应授有能聚集灰尘的突出面。
(3) the enclosure shall be granted with a prominent surface capable of gathering dust.
(4)外壳折曲处应成圆弧状,以免形成集聚灰尘的角落。所有内部焊接处,特别是密封面,均应磨光。
(4) the shell should flex arc shape, so as to avoid the formation of agglomeration of dust in the corner. All internal welds, especially the sealing surface, should be smooth.
(5)外壳尺寸应当便于对过滤器进行维修等工作。这样可能使锅炉除尘器外壳体积稍大,但因维修方便,可以避免发生事故。
(5) the size of the enclosure shall facilitate the maintenance of the filter. This may cause the boiler dust collector shell size slightly larger, but the maintenance is convenient, can avoid the occurrence of accidents.
