İtfaiye Hortumunun Alternatif Yöntemlerle Kurutulması ve Uygun Kurutucu Seçimi

Bu çalışmada amaç, hortumların yıpranmasının geciktirilmesi ve içlerindeki suyun kurutularak, hortumların ağırlığını azaltmak ve bu sayede olay esnasında en hızlı kullanımın sağlanması için belirlenmiş tekniklerden olan serme toplama yöntemlerine göre hortumların depolanabilmesidir. Mevcut durumda kurutma işlemi için kullanılan doğal kurutma özellikle hava şartlarından çabuk etkilendiği ve yavaş olduğu için alternatif yöntemlere ihtiyaç duyulmaktadır. Bu çalışma ile enerjiden ve zamandan tasarruf ederek verimsiz çalışma saatlerinde de azalmaya gidilmesi hedeflenmiştir. Kurutma öncesi gerçek koşulları dikkate alarak 30, 60 ve 90 dakika boyunca yangın hortumuna su emmesi uygulanmıştır. Denemeler mikrodalga kurutucuda 120 W, 350 W ve 460 W güç değerlerinde ve bantlı tip tünel kurutucularda ise 50 ⁰C, 60 ⁰C ve 70 ⁰C sıcaklık değerlerinde gerçekleştirilmiştir. Elde edilen sonuçlara göre nem analizi, mukavemet analizi, kuruma hızı, enerji tüketim, difüzyon katsayısı ve aktivasyon enerjisi hesaplamaları yapılmıştır. En az enerji tüketimi ve en kısa sürede kurutma 460 W güç değerinde mikrodalga kurutucu ile yapılan deneyde görülmüştür. Deneylere ait tüm sonuçlar değerlendirildiğinde iki tip kurutmanın da mekanizmaları farklı olduğu için farklı kuruma süreleri ile farklı enerji tüketimleri gözlendiği ancak genel sonuç olarak mikrodalga kurutmanın bantlı tip kurutmaya göre daha verimli gerçekleştiği görülmüştür.

Drying Of Fire Hose With Alternative Methods And Selection Of Optimal Dryer

The aim here is to delay the wearing of hoses and in order to store them and use them in the most efficient way that laying-rallying hoses are dried by decreasing their weight. With this study the objective is decreasing inefficient working hours while saving energy and time. Considering real world conditions, drying hoses are subjected to water absorption for 30, 60 and 90 minutes. Trials are executed in a microwave dryer at 120 W, 350 W and 460 W settings and in a conveyor dryer at temperatures 50 °C, 60 °C and 70 °C. Moisture analysis, strength analysis, drying rate, energy consumption, diffusion coefficient and activation energy calculations were made according to the results obtained. It has been observed that minimum consumption of energy and fastest drying occurred with the power level of 460 W in the microwave dryer. When all of the results are evaluated according to trials, it has been noted that since the mechanisms behind the two dryer systems are not similar and drying times and consumption of energies are different, the microwave dryer is more efficient than the conveyor dryer type.
