Description
Technical field
The utility model relates to increases the nitration reaction of guide shell still, and it is that the reactor of guide shell is installed on a kind of agitator, belongs to chemical field.
Background technology
Reactor is in Chemical Manufacture, for chemical reaction provides the device of reaction compartment and reaction condition, in order to improve the efficiency of reaction, conventionally in reactor, increase agitating device, accelerate material in reactor and mix, augmentation of heat transfer effect and interphase mass transfer make gas dispersed in liquid phase, solid particle is evenly suspended in liquid phase, make the evenly suspension or fully emulsified of inconsistent another liquid phase.But, mononitrotoluene nitration reaction be one have that higher thermal is dangerous, environmental change is reacted faster in reactor, only depends on agitating device, the danger of reactor is high, reactor internal environment can not be controlled evenly preferably, the production capacity of reaction is low.
Utility model content
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of nitration reaction still that increases guide shell, increase can guide shell in this reactor, and material in reactor mixes, and reaction condition is controlled easy, and security performance improves.
The nitration reaction still that increases guide shell, comprises kettle, and kettle is provided with charging aperture and discharging opening, and kettle center is provided with agitator, and agitator is fixed on centre rotational axis, and the surrounding of agitator is provided with guide shell, and guide shell is cylindrical tube shape.
Described centre rotational axis extends to above kettle top, and the upper end of centre rotational axis is connected with motor-driven.
The surrounding of described kettle is provided with heat conduction shell, and cooling housing wraps in the bottom surrounding of kettle, and the upper end of cooling housing is provided with cooling water inlet pipe and cooling water outlet tube.
Described agitator comprises vertical with centre rotational axis fixing, and agitator arm is positioned at guide shell side on the lower side, but is no more than guide shell.
The utility model, compact conformation, function is obvious, in agitator rotary course, guide shell improves mixing efficiency, has strengthened the direct mechanical shear action of agitator to liquid, define the circulating path of liquid, established the flow pattern of abundant circulation, made all materials in device all can, by the strong mixed zone in guide shell, reduce the chance of walking short circuit; Improve the security performance of mononitrotoluene nitration reaction in reactor.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand the following specific embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Visible by reference to the accompanying drawings, the nitration reaction still of this increase guide shell, comprise kettle 8, kettle 8 is provided with charging aperture 2 and discharging opening 6, kettle 8 centers are provided with agitator 10, and agitator 10 is fixed on centre rotational axis 9, and the surrounding of agitator 10 is provided with guide shell 4, guide shell 4 is cylindrical tube shape, on the sidewall of guide shell 4 without through hole.The utility model, kettle 8 is places of chemical reaction, chemical reaction material is put into kettle 8 from charging aperture 2, after chemical reaction finishes, product is discharged from discharging opening 6, the material that agitator 10 stirs in kettle 8, make mixing of materials even, improve reaction efficiency, guide shell 4 strengthens mixed effect, also strengthens radiating effect.
Described centre rotational axis 9 extends to above kettle 8 tops, and the upper end of centre rotational axis 9 and motor 1 are in transmission connection.Motor 1 drives centre rotational axis 9 rotations, thereby drives agitator 10 in the interior rotation of kettle 8, realizes stirring action.
The surrounding of described kettle 8 is provided with cooling housing 5, and cooling housing 5 wraps in the bottom surrounding of kettle 8, and the upper end of cooling housing 7 is provided with cooling water inlet pipe 3 and cooling water outlet tube 7.In cooling housing 5, cooling water is housed, cooling water enters in cooling housing 5 from cooling water inlet pipe 3, from cooling water outlet tube 7, discharges, and cooling water, in the process of cooling housing 5 of flowing through, absorbs the heat in kettle 8, and making has more stable reaction temperature in kettle 8.
The uncovered opening of upper and lower side of described guide shell 4.In Flow of Goods and Materials, accelerate heat radiation, improve the security performance of kettle 8, guide shell 4 improves mixing efficiency, strengthen the direct mechanical shear action of 10 pairs of liquid of agitator, defined the circulating path of liquid, the flow pattern of having established abundant circulation, make all materials in device all can, by the strong mixed zone in guide shell, reduce the chance of walking short circuit.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme being comprised of above technical characterictic.
