A kind of washing oil fractionating column, comprise tower main body, skirt, washing oil entrance, naphtalene oil outlet, the outlet of middle matter washing oil, heavy wash oil outlet, refluxing opening, heavy wash oil return port, overhead vapours outlet and tower tray, described tower main body is installed on the skirt, the tower bottom part body is provided with the heavy wash oil outlet, the tower lower body part is provided with the heavy wash oil return port, tower main body middle part is provided with middle matter washing oil outlet, naphtalene oil outlet and washing oil entrance, the tower body interior is provided with tower tray, tower main body top is provided with refluxing opening, and tower main body top is provided with the overhead vapours outlet; The exit of described mink cell focus outlet is provided with anti-swirl baffle, and the outside of mink cell focus outlet is provided with sleeve pipe.
The inlet tube pipeline of described washing oil entrance gos deep into the inside of tower main body, evenly is provided with outage on the inlet tube pipeline.
Described tower tray is float valve tray.
The exit of described middle matter washing oil outlet and naphtalene oil outlet is provided with recessed seal pan ．．.
Described washing oil entrance has three, lays respectively at the 18th, 20,22 layer of tower tray place.
Described naphtalene oil outlet has three, lays respectively at the 39th, 41,43 layer of tower tray place.
Described middle matter washing oil outlet has four, lays respectively at the 49th, 51,53,55 layer of tower tray place.
Compared with prior art, the beneficial effects of the utility model are:
A kind of washing oil fractionating column, have be easy to overhaul, safe and reliable, practical, scientific and reasonable for structure, characteristics that fractionating efficiency is high, the exit employing recessed seal pan ．． of described middle matter washing oil outlet and naphtalene oil outlet has guaranteed the quality of Produced Liquid; The exit of mink cell focus outlet is provided with anti-swirl baffle, has prevented the eliminating of carrying secretly of gas phase, and the sleeve pipe in the outside of mink cell focus outlet adopts live (open) steam or conduction oil insulation, prevents condensing of difficult volatile component; Because tower tray is float valve tray or bubble cap tray or sieve tray, and the pressure drop between column plate is little, flux is large, thereby makes the fractionation energy consumption low, improve washing oil fractionation oil product purity and chemical stability simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further specified:
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of washing oil fractionating column of the utility model, comprise tower main body 1, skirt 2, washing oil entrance 3, naphtalene oil outlet 4, middle matter washing oil outlet 5, heavy wash oil outlet 6, refluxing opening 7, heavy wash oil return port 8, overhead vapours outlet 9 and tower tray 10, described tower main body 1 is installed on the skirt 2, tower main body 1 bottom is provided with heavy wash oil outlet 6, tower main body 1 bottom is provided with heavy wash oil return port 8, tower main body 1 middle part is provided with middle matter washing oil outlet 5, naphtalene oil outlet 4 and washing oil entrance 3, tower main body 1 inside is provided with tower tray 10, tower main body 1 top is provided with refluxing opening 7, and tower main body 1 top is provided with overhead vapours outlet 9; The exit of described mink cell focus outlet 6 is provided with anti-swirl baffle 11, and the outside of mink cell focus outlet 6 is provided with sleeve pipe; The inlet tube pipeline 13 of described washing oil entrance 3 gos deep into the inside of tower main body 1, evenly is provided with outage 12 on the inlet tube pipeline 13; Described tower tray 10 is float valve tray; The exit of described middle matter washing oil outlet 5 and naphtalene oil outlet 4 is provided with recessed seal pan ．．; Described washing oil entrance 3 has three, lays respectively at the 18th, 20,22 layer of tower tray 10 place; Described naphtalene oil outlet 4 has three, lays respectively at the 39th, 41,43 layer of tower tray 10 place; Described middle matter washing oil outlet 5 has four, lays respectively at the 49th, 51,53,55 layer of tower tray 10 place.
