چکیده مقاله:
Power plants are often built in desert environments where the gas turbines components, including compressor vanes and rotor blades, are subject to erosion damage by sand and dust particles, and therefore results in degradation to the gas turbines parts, lowering the cycle efficiency, reducing the device lifetime, and increasing the overall cost of the operation. Thus, it is necessary to take reciprocal and preventive measures. Cylindrical and conical filter cartridges are designed for the high demands in gas turbine air filtration systems, which they filtrate the particles with diameters generally smaller than ۱۰ μm. Nowadays, the nano filter are presented for use in gas turbine inlet air systems which provides exceptionally low pressure drop at high efficiency levels (۹۹%). They have used nanotechnology to produce powerful filters such as electrospinning, the electrical charging of polymer liquids, as a means of nanofiber fabrication. High-voltage electrical fields and low production rate limit electrospinning. Solution blow spinning (SBS) has the potential to overcome some of the limitations of electrospinning and has the advantage of depositing nanofibers directly on various materials. Here, we show SBS allows for scalable production and deposition at the point and site of use as industrial production technique. This study shows the feasibility of using solution blow spinning technique to prepare PAN nanofibers on paper filter as substrate. Experimental test data showed that the water contact angle of the sample increased from about ۸۸° to ۱۲۴.۵°. Also, SBS filter has high filtration efficiency and mechanical properties than electrospinning filter.
