Mazkur tadqiqotda havo bo‘shliqli membranali distillatsiya (Air Gap Membrane Distillation – AGMD) tizimining ishlash samaradorligi Taguchi ortogonal eksperimental rejalashtirish usuli yordamida optimallashtirildi. Tadqiqotda to‘rtta asosiy ekspluatatsion parametr — oziqlantiruvchi suv harorati (T₁), sovituvchi suv harorati (T₂), oziqlantiruvchi oqim sarfi (V₁) va sovituvchi oqim sarfi (V₂) tahlil qilindi. Jarayon samaradorligi distillyat oqimi, distillyat massasi va mahsulotning elektr o‘tkazuvchanligi bo‘yicha baholandi.
Materiallar va usullarTajriba Ispaniyaning PURA-Lab (PSA, CIEMAT) laboratoriyasida havo bo‘shliqli membranali distillatsiya qurilmasida o‘tkazildi. Tadqiqotda 3 mm havo bo‘shlig‘iga ega gidrofob PTFE tekis membranadan foydalanildi. Oziqlantiruvchi va sovituvchi oqimlar qarama-qarshi yo‘nalishda harakatlantirildi, harorat esa termostatli vannalar yordamida (±0,5 °C) boshqarildi. Jarayonni optimallashtirish L8 Taguchi ortogonal reja asosida amalga oshirildi. O‘rganilgan parametrlar: T₁ = 70–80 °C, T₂ = 20–25 °C, V₁ = 100–150 L/soat va V₂ = 100–150 L/soat. Tahlilda distillyat oqimi, distillyat massasi va mahsulot elektr o‘tkazuvchanligi statistik usullar yordamida baholandi.
NatijalarEksperimental natijalarga ko‘ra, distillyat oqimi 36,72–122,11 L/soat, distillyat massasi 0,158–1,328 kg, mahsulot elektr o‘tkazuvchanligi esa 1,23–3,69 μS/cm oralig‘ida o‘zgardi. Taguchi tahlili oziqlantiruvchi suv harorati (T₁) eng muhim omil ekanligini ko‘rsatdi; u distillyat oqimidagi o‘zgarishning 56,4 %, distillyat massasidagi o‘zgarishning esa 69,8 % ini belgilaydi. T₁ ning 70 °C dan 80 °C gacha oshirilishi distillyat oqimi va massasining 60 % dan ortiq kamayishiga olib keldi. Optimal ish rejimi T₁ = 70 °C, T₂ = 20 °C, V₁ = 150 L/soat va V₂ = 100 L/soat bo‘lganda kuzatildi. Ushbu sharoitda maksimal distillyat oqimi 118 L/soat va yuqori sifatli mahsulot (1,3 μS/cm) olindi.
XulosaTaguchi eksperimental rejalashtirish usuli AGMD tizimining optimal ish parametrlarini aniqlashda yuqori samaradorlikka ega ekanligi tasdiqlandi. Oziqlantiruvchi suv harorati tizim unumdorligiga eng katta ta’sir ko‘rsatuvchi omil bo‘lib, optimal parametrlarni tanlash distillyat unumdorligini oshirish va mahsulot sifatini yaxshilash imkonini beradi.
