Abstract :
A novel dehydration device was put forward to reduce the mist content in blast furnace gas. Aiming at the complex two-phase flow of curved-plate dehydration equipment, its capabilities were studied by changing the structures and operation parameters. The effects of all the factors on dehydration efficiency and pressure loss were also discussed. The results indicate that the optimum gas velocity is 1.75~2.25 m/s, the space between the curved-plates is 5~7.5 mm. and the length of the inclined plate is 200~250 mm. Moreover, the best ratio of liquid and gas is 0.2~0.25 L/m3, and the optimized particle size of water sprays is 100~500 μm. In the conditions described above, the highest dehydration efficiency and the smallest pressure loss can be obtained.
