When needing to carry out removing water, excessive octanol and other impurities in dioctyl phthalate production process, first
Superheated steam is sent in tower body 1 by steam inlet 4, steam is moved up along tower body 1, and steam passes through grid 102
Support component 10 enters in the first filler 5, and the first inlet tube 8, the second inlet tube 7 are passed through liquid into tower body 1 simultaneously at this time, and
The liquid being discharged in first inlet tube 8, the second inlet tube 7, which passes through liquid distribution trough 9, disperses liquid, passes through liquid point
Liquid after cloth device 9 disperses is fallen in the first filler 5 by self weight, enters the liquid in the first filler 5 and entrance at this time
It is adequately reacted to the steam in the first filler 5, so that water, excessive octanol and the other impurities in steam are tentatively deviate from,
And the water, excessive octanol and other impurities in the steam tentatively deviate from is by the bottom dropped out from trend tower body 1, and it is tentatively de-
Except the gas generated after steam then continues to move upwards along tower body 1.
When the gas generated after tentatively removing steam enters in the second filler 6 across 102 support component 10 of grid, the
Two fillers 6 absorb vapor remaining in gas, octanol and other impurities, to make the gas by the second filler 6
It is purer, dry；Finally, it is directly discharged from gas outlet 3 by the first filler 5 treated gas, and falls to 1 bottom of tower body
Then tower body 1 directly is discharged by liquid outlet 2 in the liquid in portion.
