Hava filtresi içindeki akış ve titreşim deseninin karşılaştırılması- deneysel çalışma

Bu çalışmada, bir hava filtresi imal edilmiş ve filtre kâğıdı üzerinde sıcaklık ve titreşim büyüklüğü değişimi, ters darbeli temizleme yapılarak deneysel olarak tespit edilmiştir. Bu amaçla, sıkıştırılmış temiz ve kuru hava, akışa ters yönlü olarak filtreye doğru 10 ms süreyle 827 kPa sabit basınçla serbest bırakılmıştır. Filtre kâğıdının darbeli temizlenmesi için darbe mesafesi ve lüle etkisi, farklı lüle-filtre mesafeleri ve farklı lüle konumlarında deneysel olarak gözlemlenmiştir. Titreşim genliklerinin büyüklüğü ivme sensörleriyle, sıcaklık değişimleri ise termal kamera kullanılarak elde edilmiştir. Lülenin faklı konumlarda ve mesafelerde kullanımı, titreşim ve sıcaklık dağılımını desenlerini etkilemektedir. Deneylerin sonucunda en homojen titreşim ve sıcaklık dağılımının lülenin dikey konumunda olduğu belirlenmiştir.

Comparison between flow and vibration patterns in air filter-experimental study

In this study, an air filter was manufactured and variation of temperature and vibration magnitude on filter paper were investigated experimentally by inverse pulse cleaning. For this purpose, compressed clean and dried air was released throughout in the inverse direction of the flow for 10 msec under 827 kPa constant pressure. The effect of nozzle and pulse distance for pulse cleaning of filter paper were observed experimentally under different nozzle-filter distance and different nozzle positions. The magnitude of vibrations and variation of temperature obtained using accelerometers and thermal camera respectively. The usage of nozzle within the different positions and distance effect vibration and temperature patterns. As a result of experimental study, it was determined the most homogeneous vibration and temperature distributions were at vertical position of nozzle.
