Embodiment 1
[0029] a kind of like figure 1 The fine-hole sieve plate bubble column shown includes a cylinder body 1, an air inlet 2, an air outlet 3, a liquid spray pipe 5, a sieve plate 6, an overflow plate 7, a liquid suction and ventilation net 8, and an auxiliary liquid inlet 11 and demister9. The gas inlet 2 is arranged at the lower part of the cylinder body and above the liquid level; the gas outlet 3 is arranged at the upper part of the cylinder body and above the bubbling layer of the tray.
[0030] The bubble column tray in this embodiment is a fine-pore sieve plate 6, which is rolled and formed by metal sheets or ceramic fiber sheets, or stamped and formed by metal sheets, or injection molded. Its structural parameters are 3-30 mm in height, 0.5-5 mm in average aperture, and 0.3-0.9 in opening ratio. One side of the sieve plate 6 is provided with an overflow plate 7, and there are many V-shaped notches on the top of the overflow plate, which are 10-50mm higher than the sieve p...
Embodiment 2
[0039] image 3 The fine-pore sieve plate bubble column shown is a bubble column with multiple layers of fine-pore sieve plates. It includes a cylinder body 1, an air inlet 2, an air outlet 3, a liquid spray pipe 5, a sieve plate 6, an overflow plate 7, a liquid suction and ventilation net 8, an auxiliary liquid inlet pipe 11 and a demister 9. The gas inlet 2 is arranged at the lower part of the cylinder body and above the liquid level; the gas outlet 3 is arranged at the upper part of the cylinder body and above the bubbling layer of the tray.
[0040] The bubble column tray in this embodiment is a microchannel fine-hole sieve plate 6, which is a screen with a certain height and spreads over the microporous channels. The preferred structural parameters are 10-20mm in height, 1-3mm in average pore size, 0.6 to 0.8. One side of the sieve plate 6 is provided with an overflow plate 7, and there are many V-shaped notches on the top of the overflow plate.
