Description
Technical field
The utility model relates to a kind of esterifying kettle device that has the intubate bearing, relates in particular to a kind of commercial plant that is applied in the enamel reaction still of acetate industry Esterification Stage.
Background technology
At present; The esterification production process of acetate generally all is the preheating of elder generation through reboiler; Enter in the esterifying kettle through intubate then; Through the heat in the esterifying kettle material is reacted again, get in the esterification column via trap through riser behind reaction product and a spot of material gasification and separate, separate thereby accomplish preliminary esterification.
In the enamel reaction still of existing bigger volume; The height of enamel reaction still and internal diameter are all corresponding have been increased much; Thereby to use long intubate relatively, because existing intubate bottom is not supported, intubate is easy to rupture; The very big chance of intubate of fracture is hit the surface at enamel down, breaks the inwall of enamel reaction still easily and causes production accident.And owing to keep in repair relatively difficulty behind the quick-fried magnetic of enamel reaction still, and maintenance cost is higher, therefore designs a kind of rational supporting seat support intubate protection enamel reaction still, steady production are very important.
Summary of the invention
The utility model is in order to overcome the deficiency of prior art; Especially a kind of esterifying kettle device that designs in order to prevent the intubate fracture specially; Because the intubation length in the more large-scale enamel reaction still is long; The stress of the liquid-phase generating in the enamel reaction still still is bigger, and the less enamel reaction still of volume shakes more easily relatively, so prevent that long intubate from fracture taking place is very important.
The utility model solves the technical scheme that its technical problem adopted: a kind of esterifying kettle device that has the intubate bearing; Riser by being connected between the intubate that is connected between enamel esterifying kettle, reboiler, esterification column, enamel esterifying kettle and the reboiler, enamel esterifying kettle and the esterification column is formed; Be mounted with in the wherein aforesaid enamel esterifying kettle one have corrosion resistance the intubate supporting seat, the intubate supporting seat is connected with intubate bottom in inserting the enamel esterifying kettle and supports intubate.The intubate supporting seat is set, and promptly through below intubate, increasing a support force, when guaranteeing that support force is enough, the amplitude that can also guarantee the intubate double swerve is in the scope of elastic strain.
As the further design to the aforementioned techniques scheme: the side stay pipe that aforesaid intubate supporting seat is fixedly connected by a main stay pipe, main stay pipe top, the brace summer that connects main stay pipe and side stay pipe are formed.Through of the support of intubate supporting seat both sides to intubate; All stress all concentrates on the centre of brace summer, when intubate is rocked because of between intubate and the intubate supporting seat certain buffer distance being arranged, so center of effort is in fixing point and central point change; Become alternate stress, but major part is at central point.In addition, through the interlude of reinforcement intubate supporting seat, thereby reach the ideal effect that supports intubate.Since present all kinds of reactions all be with the concentrated sulfuric acid with deep-etching effect as catalyst, we both can select corrosion resistant PTFE lining on intubate supporting seat surface, also can select to make intubate supporting seats by corrosion resistant other metal materials.
As the further design again to the aforementioned techniques scheme: aforesaid intubate below is provided with the aperture that several are positioned at enamel reaction still liquid phase liquid level below.For guaranteeing that raw material can get into enamel reaction still through intubate smoothly, suitably below intubate, evenly open several less relatively, apertures of being used to spread material, need guarantee that position of opening is positioned at liquid phase liquid level below.
In sum, the esterifying kettle device of the utility model is compared with the esterifying kettle device of prior art, has following advantage: in the bigger enamel reaction still of volume; Long intubate has obtained effective support; Reduced the possibility of intubate generation fracture, can reduce the frequency of maintenance, can normally or better move by ensuring equipment; Greatly reduce the maintenance cost of equipment again, guaranteed the stable of production.Simultaneously, the intubate clamping support is simple, can in the liquid phase material of severe corrosive, work.

The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further to describe explanation.
Embodiment 1
The concrete scheme of present embodiment is: a kind of esterifying kettle device that has the intubate bearing; As shown in Figure 1; Riser 6 by being connected between the intubate 5 that is connected between enamel esterifying kettle 1, reboiler 2, esterification column 3, enamel esterifying kettle and the reboiler, enamel esterifying kettle and the esterification column is formed; Be mounted with in the enamel esterifying kettle one have corrosion resistance intubate supporting seat 7, the intubate supporting seat is connected with intubate bottom in inserting the enamel esterifying kettle and supports intubate.Because the reactant liquor phase materials in the enamel reaction still acutely seethes, and intubate is produced sizable moment, especially when the length of intubate was big more, moment was also big more, so must below intubate, fix an intubate supporting seat.The intubate supporting seat is set, and promptly through below intubate, increasing a support force, when guaranteeing that support force is enough, the amplitude that can also guarantee the intubate double swerve is in the scope of elastic strain.Raw material at first is heated to certain temperature through reboiler; Raw material enters in the enamel reaction still through intubate then, and after in enamel reaction still, fully reacting, the admixture of gas of high temperature enters into esterification column to be separated; Follow a spot of raw material in the mixture, and most water.
Like Fig. 2, shown in Figure 3, the side stay pipe 9 that aforesaid intubate supporting seat is fixedly connected by a main stay pipe 8, main stay pipe top, the brace summer 10 that connects main stay pipe and side stay pipe are formed.Main stay pipe is processed by a bigger thick-walled pipe of diameter; Four side stay pipes of main stay pipe top welding; The side stay pipe is processed by less relatively pipe, processes brace summer through four pipes with side stay pipe same size again, and brace summer is in order to the size of fixation side stay pipe.Through of the support of intubate supporting seat both sides to intubate; All stress all concentrates on the centre of brace summer, when intubate is rocked because of between intubate and the intubate supporting seat certain buffer distance being arranged, so center of effort is in fixing point and central point change; Become alternate stress, but major part is at central point.In addition, through the interlude of reinforcement intubate supporting seat, thereby reach the ideal effect that supports intubate.
Aforesaid intubate below is provided with the aperture that several are positioned at enamel reaction still liquid phase liquid level below.For guaranteeing that raw material can get into enamel reaction still through intubate smoothly, suitably below intubate, evenly open several less relatively, apertures of being used to spread material, need guarantee that position of opening is positioned at liquid phase liquid level below.
Except that the embodiment of above structure, every and esterifying kettle device the utility model structural similarity falls within the protection domain of the utility model too.
