Abstract

顺风角风机。该风机是在原有风机的基础上在风机出口法兰上边根部开始接45°角板。从而提高了风机的风压和风量,降低了炉灰含炭量,节约能源。

Description

顺风角风机
本实用新型涉及一种节能风机——特别是一种顺风角风机。
目前国内外生产的各种型号风机,都不能充分发挥其性能,为此,使用厂家为了得到所需风量及风压,一般都选用大功率风机,造成资金和电的浪费,有些锅炉引风机的风量、风压不够,正压运行,冒烟等,只好堵鼓风机吸口来烧炉,这样就降低了鼓风量及风压,造成炉膛底层结焦,上层烧不尽,浪费了大量的能源。
风机的出口风筒截面积应该大于或等于吸口风筒截面积,才能达到风阻平衡,但所有大小风机的出风口截面积小于或等于吸风口截面积,尤其都没有顺风角,所以风机出口上层的风压及风阻比底层大好几倍,为此,解决风机出口上层出风角度及截面积是能否充分发挥风机性能的关键所在。
本实用新型的目的是要提供一种节约能源、结构简单、效率高的改进的风机——顺风角风机。
本实用新型的目的是这样实现的,在风机出口法兰上边根部开始接45°角板,其高度为出口整个法兰高度的1/2,同时把原上层板割掉,按顺风角高度接三面即可,有的风机的出口截面积等于吸口,但没有顺风角的只要接出顺风角,顺风筒接半米左右,即得同样的效果。
本实用新型是从84年至今在4—10T/h锅炉的引风机上试验了9台次,其电流下降10T/h炉风机15%左右,4T/h炉风机8%左右,风量提高2000m3/h,风压提高400PQ,不冒烟,降低炉灰含炭量,改风机只需一名电焊工,一名力工,一天就完工。改造费:人工费及材料费共计400元,节约能源,按4T/h炉测算,年节电8000度,节约30T标准煤,年经济效益1万元以上。
本实用新型的具体结构由以下实施例及其附图给出。
图1为顺风角风机结构示意图。
图2为旧风机改造成顺风角风机结构示意图。
下面结合附图详细说明本实用新型的具体结构和使用情况。
该风机的风机主体1和现有的风机完全相同,只是在风机出口法兰上边根部开始接45°角板2,其高度h为出口整个法兰高度的1/2,如是旧风机改制成顺风角风机,可把原上层板3割掉,按顺风角度在出口法兰上边根部接45°角板2,然后按顺风角高度接三面即可。
