At present, when producing CBS, quantitative cyclohexylamine and water are put into reactor, open and stir.Then add rubber accelerator M, drip the liquor natrii hypochloritis behind the stirring certain hour, temperature is controlled at 25--50 ℃ continues reaction.Reaction finishes, and emits material after being cooled to 25 ℃.Completely reacted material put into wash hopper, utilize the siphon of vavuum pump that the mother liquor in the material is sucked in the mother liquor tank, the washed material hopper of packing into is transported to dry post.Mother liquor siphon in the mother liquor tank enters distillation still, becomes mother liquor steam after heating and enters recovery amine storage tank by the condensation recovery.Be transported to the material in dry post, send in the kneader and mediate, to carry out granulation ready for material.Mother liquor namely contains the solution of cyclohexylamine, is to utilize the steam direct heating mother liquor when mother liquor is carried out Distillation recovery, and mother liquor is heated and becomes mother liquor steam, and mother liquor steam carries out rectifying through rectifying column, then obtains cyclohexylamine.Directly steam is passed into mother liquor at present and heat, steam can not be recycled, and has caused waste and the heat-energy losses of steam.And rectifying column only has a production capacity limited; Simple baffling orifice plate is only arranged in the rectifying column, and organic efficiency is low, and the cyclohexylamine of recovery is of poor quality.
The utility model content
Technical problem to be solved in the utility model is: for the deficiency that prior art exists, provide a kind of heating steam recoverable, the rectifying production capacity is high, organic efficiency is high and the measured cyclohexylamine rectifying device of producing for CBS of the cyclohexylamine matter that reclaims.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Be used for the cyclohexylamine rectifying device that CBS produces, comprise distillation still and the rectifying column that is communicated with described distillation still, be provided with the baffling orifice plate in the described rectifying column, described distillation still inner chamber is provided with U-shaped heater, described U-shaped heater comprises the U-shaped heating tube bundle that is positioned at described distillation still inner chamber, the two ends of described U-shaped heating tube bundle are respectively steam inlet and condensation-water drain, and described steam inlet and condensation-water drain run through described distillation still outer wall.
As a kind of scheme, described distillation still top is provided with at least two rectifying columns, is filled with filler between the baffling orifice plate in the described rectifying column.
As a kind of scheme, described distillation still top is provided with two rectifying columns that are set up in parallel.
As further scheme, the top of described two rectifying columns that are set up in parallel is equipped with the gaseous phase outlet that is communicated with condenser.
As a kind of scheme, described filler is Pall ring.
As a kind of scheme, described steam inlet and condensation-water drain are setting up and down, and steam inlet is arranged on the top of described condensation-water drain.
As a kind of scheme, described distillation still top is respectively equipped with evacuation port, mother liquor import and alkali import.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
Be filled with filler in the rectifying column of the present utility model, increased the time of staying of mother liquor steam in rectifying column, improved rectification effect and organic efficiency, the cyclohexylamine quality of recovery is good.Described distillation still inner chamber is provided with U-shaped heater.Steam enters heating tube bundle by the steam inlet of U-shaped heater, and with the heating of the mother liquor in the distillation still, condensed water out enters condensation water recovery system afterwards by the condensation-water drain of U-shaped heater, can send into other workshop sections that need and recycle.The distillation still top is provided with at least one rectifying column, has improved distillation efficiency, has shortened distillation time.
