Description

燃气轮机进气装置
技术领域
本实用新型涉及一种燃气轮机进气装置。
技术背景
燃气轮机对进气气流的品质要求较高,如果进气中有灰尘颗粒进入燃气轮机就会造成压气机叶片表面积垢、叶片磨损、燃气轮机有效输出功率减少。为了防止灰尘颗粒随空气进入,一般在燃气轮机进气口前设置单级过滤器。这种单级过滤器能减少一部分灰尘颗粒进入燃机,但在多灰尘地区或气候环境恶劣的情况下,单级过滤器往往容易堵塞,使气流速度升高,进气压损增大,影响过滤器的寿命。若遇到雨、雪天气,水滴随气流进入过滤器,打湿滤芯,直接造成过滤器的损坏。
发明内容
本实用新型针对上述发明容易堵塞、损坏过滤器的不足,提出了一种由三级过滤器构成的既能保证进气过滤效率又能延长过滤器使用寿命的燃气轮机进气装置。
本实用新型是在燃气轮机箱体内固有带压损测量传感器的蜗壳,蜗壳与燃气轮机进气口连接,上、下法兰固接有一连接气道,在支架上依次安装有消音器,收缩气道,反吹装置,其主要特点是在支架上还依次串接有带防护罩的百叶窗过滤器,含栅板的“V”型过滤器,含有百褶状滤芯的精过滤器。
采用本实用新型的进气装置,首先由百叶窗过滤器过滤掉一些粗大的灰尘颗粒,挡住飞禽,昆虫的侵入,“V”型过滤器可以过滤90%的5um以上的灰尘颗粒和大部分水滴,且压损较小。精过滤器对于小于5um的灰尘,过滤效率大于99%,且滤芯具有较好的防潮性能。由于采用三级过滤器,前两级粗过滤器过滤了大部分粗大灰尘颗粒和水滴,进入精过滤器的灰尘和水分较少,减小了精过滤器的工作压力,防止了过滤器的损坏,延长了使用寿命。
附图说明
图1为本实用新型结构示意图
图中1蜗壳,2压损测量传感器,3下法兰,4连接气道,5上法兰,6燃气轮机箱体,7转弯气道,8支架,9消音器,10收缩气道,11反吹装置,12精过滤器,13“V”型过滤器,14防护罩,15百叶窗过滤器。
具体实施方式
在燃机箱体6内固有带压损测量传感器2的蜗壳1,蜗壳与燃气轮机进气口连接使进气均匀,其上的连接气道4由上法兰5、下法兰3连接。在百叶窗过滤器15上设有防止雨水、雪、灰尘等进入的防护罩14,空气首先被带防护罩14的百叶窗过滤器15初过滤,过滤掉粗大灰尘颗粒与水滴的空气进入内设有栅板的“V”型过滤器13,“V”型过滤器对含有细小灰尘颗粒与水滴的空气作进一步分离、过滤。最后进入含有经防潮处理的百褶状滤芯的精过滤器12,过滤后的空气经消音器9进入燃气轮机。精过滤器12运行一段时间后其上吸附了一定的灰尘,流阻损失增大,此时,设于其后的反吹装置11自动清除积在滤芯上的灰尘,使空气流通顺畅,无需人工清理。
为使进气气流流动均匀,减小压损,在精过滤器12与消音器9之间,设有一段收缩气道10。
