Detailed Description
as shown in fig. 1 and 2, the utility model discloses rectification knockout tower is equipped with subdivision board 5 just directly over every column plate 4 subdivision board 5 with but 4 edge of column plate detachable connections, subdivision board 5 middle zone with be equipped with the clearance between the column plate 4, be equipped with subdivision hole 12 on the subdivision board 5, subdivision hole 12 aperture is less than 11 apertures of discharge orifice on the column plate 4, wherein, discharge orifice 11 is the aperture and is in by the last bell mouth that diminishes gradually down in 4 thickness directions of column plate, 11 apertures of discharge orifice with contained angle α between 11 centraxonial in the discharge orifice is 15, subdivision hole 12 apertures is less than 11 throat end apertures in the discharge orifice.
In this embodiment, as shown in fig. 3 and 4, the fine dividing plate 5 is a spherical plate, and one side of the fine dividing plate 5 adjacent to the downcomer 2 is detachably connected to the sidewall of the overflow weir, and one side of the fine dividing plate 5 adjacent to the receiving tray 3 and the tray 4 form an air escape opening. The spherical panels are used as the subdivision plates 5, the tower plate 4 can be partitioned according to different bubble escape speeds, so that bubbles between the tower plate 4 and the subdivision plates 5 far away from the central area of the tower plate 4 can quickly escape to the upper part of the subdivision plates 5 through the subdivision holes 12, meanwhile, the speed of the bubbles between the tower plate 4 and the subdivision plates 5 in the central area of the tower plate 4 escaping upwards through the subdivision holes 12 is favorably delayed, the gas-liquid contact time is prolonged, the amount of mist is reduced, and the efficiency of a single tower plate is improved.
In actual production, a material to be rectified and separated is added into the tower body 1 through the feeding pipe 8, then high-temperature gas for heating is input into the tower body 1 through the air inlet pipe 9, after the material to be rectified and separated is heated by the high-temperature gas, substances with lower boiling points in the material to be rectified and separated are converted into gaseous states and ascend along the tower body 1, and when steam formed by the substances with lower boiling points meets the tower plate 4 with lower temperature, the steam is condensed into liquid drops. When the temperature in the whole tower body 1 rises to the normal working temperature (namely the temperature required by the materials to be separated in the materials to be rectified and separated can be obtained), the fraction enters the condenser through the air outlet pipe 6 and is condensed into a product, and a part of the product flows back into the tower body 1 through the return pipe 7. And the material with higher boiling point in the material to be rectified and separated is discharged out of the tower body 1 through the discharge pipe 10, wherein a part of the material with higher boiling point flows into the reboiler to be heated to form high-temperature gas, and then the high-temperature gas enters the tower body 1 through the gas inlet pipe 9 to be heated to the material to be rectified and separated.
In the rectification separation process, when the air flow through the through-flow hole 11 through the tray 4 is large, a part of the gas will be discharged out of the space enclosed by the fine-dividing plate 5 and the tray 4 through the air escape opening, while the rest of the gas will escape upwards through the fine-dividing hole 12, and when the air flow through the tray 4 through the through-flow hole 11 is small, the liquid overflowing from the liquid receiving tray 3 will block the bubbles in the space enclosed by the fine-dividing plate 5 and the tray 4. When the liquid amount on the tower plate 4 is less, the fine-dividing plate 5 can break bubbles in the mist, which is beneficial to gas-liquid heat exchange and gas heat transfer to the liquid on the upper layer of the tower plate 4.
Moreover, the through-flow holes 11 are tapered holes, so that the restriction of the ascending gas flow is facilitated, the pressurization is facilitated after the ascending gas flow passes through the tower plate 4 under the blocking of the fine-dividing plate 5, the dispersion of the gas flow is not large, the bubbles formed in the space enclosed by the fine-dividing plate 5 and the tower plate 4 are divided into bubbles with small volume through the fine-dividing holes 12, and the heat exchange between the high-temperature gas and the liquid is facilitated, so that the efficiency of the single tower plate is improved.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications are possible which remain within the scope of the appended claims.
