Rayvaldo, Fandi Akhmad (2018) Pengembangan Filter Partikulat Pm0.1 Berbasis Elektrostatis Tegangan Rendah Arus Ac Untuk Sistem Pembuangan Emisi Sepeda Motor. Sarjana thesis, Universitas Brawijaya.
Abstract
Partikel ultrafine telah dikenal sebagai senyawa toxic bagi kesehatan manusia. Ada banyak teknologi filtrasi yang dikembangkan untuk mengurangi emisi partikel ultrafine di udara ambient. Studi ini bertujuan untuk mengembangkan filter berbasis elektrostatis untuk mengurangi konsentrasi partikel ultrafine yang dipancarkan oleh sistem pembuangan emisi sepeda motor. Penelitian ini menggunakan tiga sepeda motor dalam kondisi standar sebagai sampel sumber partikel ultrafine. Filter terbuat dari pelat aluminium dengan ketebalan 2,1 x 10-2 cm. Dalam penelitian ini menggunakan empat buah filter partikulat yang berbeda dengan variasi jarak antar plat, di mana: F1 (3,6 cm), F2 (1,8 cm), F3 (1,2 cm), dan F4 (0,9 cm). Test bench laboratorium digunakan untuk menyelidiki efisiensi filtrasi dari filter yang dikembangkan. Ada tiga variasi frekuensi yang digunakan dalam penelitian ini, antara lain: 60Hz, 684 Hz, dan 1309 Hz. Efisiensi filter ditentukan sebagai rasio antara konsentrasi partikel ultrafine sebelum dan sesudah melewati filter. Konsentrasi partikel ultrafine diukur menggunakan P-Trak Ultrafine Particle Counter (TSI, Model 8525) selama lima menit dengan interval satu menit (tiga pengukuran berulang). Hasil penelitian menunjukkan bahwa efisiensi filter tergantung pada gap filter, temperatur emisi, tegangan elektrostatik, frekuensi listrik, dan laju aliran emisi.
English Abstract
Ultrafine particles have been known as the toxic agents for human health. There were many filtration technologies that were developed to reduce the ultrafine particle concentration in the ambient air. In this study, we aimed to develop an electrostatic-based filter to reduce the concentration of ultrafine particles emitted by the motorcycle exhaust system. This study used three standard condition motorcycles as the ultrafine particle source samples. The filters were made of aluminum plates with the thickness of 2.1 x 10-2 cm. There were four different filters in different filter gaps: F1 (3.6 cm), F2 (1.8 cm), F3 (1.2 cm), and F4 (0.9 cm). A laboratory-bench tests are used to investigate the filtration efficiency of the developed filters. The frequency was varied into 60Hz, 684 Hz, and 1309 Hz. The filter efficiency is determined as the ratio between the concentration of ultrafine particle before and after passing through the filter. The concentration of ultrafine particles was measured using a P-Trak Ultrafine Particle Counter (TSI, Model 8525) for five minutes at one minute intervals (three repeated measurements). The results showed that the efficiency of the filter depends on the gap filter, emission temperature, electrostatic voltage, electrical frequency, and flow rate
