FIELD: power engineering. SUBSTANCE: packing may be used in biological cleaning filters. Packing has vertical crimped netted sheets made of intercrossing parallel nonmetallic threads with parallelogram-shaped cells formed between the. Space l between threads equals 10-25 mm. Thread thickness delta= 1.5-4.0 mm. Crimping is performed at angle alpha=60-80 deg with space m = 30-60 mm and crimp height h = 30-60 mm. EFFECT: reduced aerodynamic resistance. 3 cl, 2 dwg |
