Comparison Between Flow And Vibration Patterns In Air Filter - Experimental Study

In this study, an air filter was manufactuted 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 temparature obtained using accelerometers and thermal camera respectively. The usage of nozzle within the different positions and distance effect vibration and tempapature patterns. As a result of experimental study, it was determined the most homogeneous vibration and temperature distributions were at vertical position of nozzle.

Hava Filtresi Ýçindeki Akýþ ve Titreþim Deseninin Karþýlaþtýrýlmasý- Deneysel Çalýþma

Bu çalýþmada, bir hava filtresi imal edilmiþ ve filtre kaðýdý üzerinde sýcaklýk ve titreþim büyüklüðü deðiþimi, ters darbeli temizleme yapýlarak deneysel olarak tespit edilmiþtir. Bu amaçla, sýkýþtýrýlmýþ temiz ve kuru hava, akýþa ters yönlü olarak filtreye doðru 10ms süreyle 827 kPa sabit basýnçla serbest býrakýlmýþtýr. Filtre kaðýdýnýn darbeli temizlenmesi için darbe mesafesi ve lüle etkisi, farklý lüle-filtre mesafeleri ve farklý lüle konumlarýnda deneysel olarak gözlemlenmiþtir. Titreþim genliklerinin büyüklüðü ivme sensörleriyle, sýcaklýk deðiþimleri ise termal kamera kullanýlarak elde edilmiþtir. Lülenin faklý konumlarda ve mesafelerde kullanýmý, titreþim ve sýcaklýk daðýlýmýný desenlerini etkilemektedir. Deneylerin sonucunda en homojen titreþim ve sýcaklýk daðýlýmýnýn lülenin dikey konumunda olduðu belirlenmiþtir.
