Detailed description of the invention
Below in conjunction with each accompanying drawing and illustrated embodiment, the utility model is described further:
Embodiment 1 of the present utility model as Figure 1-3:
A methylbenzene azeotropic destilling tower, comprises tower reactor 1, tower body 2, heat-insulation layer 3, material pipe 4, first pressure valve 51, second pressure valve 52, chuck pressure valve 6, is located at the gas distributor 7 in tower reactor 1 and is positioned at the filler 8 of this gas distributor 7 upper end.Tower body 2 is installed in tower reactor 1, material pipe 4 is connected in tower reactor 1 by outside, and injection methylbenzene azeotropic destilling tower is inner, first pressure valve 51, second pressure valve 52 is located on material pipe 4 successively, heat-insulation layer 3 is located at the outer wall of tower reactor 1 and tower body 2, it is characterized in that: straight shape material shower 4 stretches in described tower body 2, material pipe 4 cross section is open circles, cross section obliquely 45 ° of both sides is provided with spray apertures (spray apertures does not mark in the drawings), gas distributor 7 entirety is in annular, cross section is hollow cylinder, the circle diameter of gas distributor 7 is the 60%-80% of tower reactor 1 interior diameter, gas distributor 7 is provided with distribution hole 71, the material that described gas distributor 7 is communicated with chuck pressure valve 6, material pipe 4 imports is ejected into from spray apertures on the filler 8 in methylbenzene azeotropic destilling tower.Distribution hole 71 is arranged on tiltedly 30 ° of angles, both sides place, below, gas distributor 7 hollow cylinder cross section.Filler 8 is the corrugated filler of stainless steel wire.Heat-insulation layer 3 is rock wool material.Gas distributor 7 is processed by seamless steel pipe.
In practice, with not gram reaction preparation one benzyl toluene and dibenzyl toluene, condensation liquid removes catalyst and hydrogen chloride through washing and alkali cleaning.Material enters tower reactor from material pipe 4, when liquid level is higher than gas distributor 7, first opening clamp cover pressure valve 6 is heated to 90 DEG C, open the first pressure valve 51 again, finely tune the second pressure valve 52, liquid in tower reactor can normally be seethed with excitement and not rise still, it is inner that organic matter material enters tower body 2 by material pipe 4, in 84-90 DEG C of situation, form azeotropic mixture from 80% toluene and 20% water and leave destilling tower condensation recycling, kettle base solution is product benzyl toluene mixture, is distributed on filler 8.This tower is economize energy due to frozen-free backflow, owing to being that air-distillation reduces toluene loss, consolidating utility model not only energy-conservation but also environmental protection, carry out B-grade condensation process without the need to arranging condenser at tower top, saves the consumption of the chilled brine of a large amount of energy.And the volatile quantity of disulfonic gas reduces, and protects environment.
The utility model is not limited to the restriction of above-described embodiment, and the equivalencing means that other various those skilled in the art skillfully grasp and distortion all fall in the scope of the utility model protection.Protection domain of the present utility model is specifically defined by appended claims.
