Description
Technical field
This utility model is related to nitrify equipment technical field, is related specifically to a kind of continuous nitrification for experimental branch line certainly
Dynamic control device.
Background technology
Nitration reaction is that nitro is introduced in organic molecule（-NO2）Course of reaction.Aliphatic compound has when nitrifying
The side reaction of oxidation-scission of link, it is industrial seldom to adopt.Nitromethane, nitroethane, four kinds of nitroparaffin hydrocarbon gas of 1- and 2- nitropropanes
Phase method production process, is the american goods solvent company exploitation thirties.The method is still to produce the main work of nitroparaffins so far
Industry method.Additionally, nitrification also refers to the forming process of nitrogen oxide.
Nitrifying process is carried out in the liquid phase, generally using tank reactor.According to nitrating agent and the difference of medium, can adopt
Enamel still, steel kettle, cast iron kettle or rustless steel kettle.With during mixed acid nitrification in order to remove reaction heat as soon as possible to keep suitable reaction
Temperature, in addition to cooling down using chuck, also installs cooling worm in kettle.The little nitrifying process of yield adopts intermittently operated mostly.
The big nitrifying process of yield can be operated continuously, and using autoclave continuous nitrification reactor or ring-like continuous nitrification reactor, carry out many
Platform series connection completes nitration reaction.The advantage of ring-like continuous nitrification reactor is that heat transfer area is big, and stirring is good, and production capacity is big,
Many nitro compounds of by-product and nitrophenols are few.
Nitrator refers to that for carrying out the reactor of nitration reaction the tank reactor for generally being stirred using band by kettle, is stirred
Mix the composition such as device, actuating device, chuck or coiled pipe (being heated or cooled if desired).Nitrator is generally intermittently operated, material
Added in kettle by top, promptly mix in the presence of agitator and carry out nitration reaction.If necessary to heat, can be in chuck
Or steam in coiled pipe, is passed through, if necessary to cool down, cooling water or cryogen can be passed through.
Existing nitrator is generally single chamber nitrator, and artificial constantly charging is needed during use, and in order to ensure
Nitration reaction it is abundant, in addition it is also necessary to be stirred for a long time, will also be according to the change of liquid level and temperature, to stirring during stirring
Mix speed to be adjusted, the safety of production efficiency and personnel has been had a strong impact on using traditional nitrator.
The content of the invention
Technical problem to be solved in the utility model is the defect for overcoming prior art, there is provided a kind of simple structure, energy
It is enough to be stirred according to the change of temperature and liquid level automatically, energy resource consumption is reduced, improve production efficiency reduces the company of security risk
Continuous nitrification automaton.
To achieve these goals, this utility model is employed the following technical solutions：
Continuous nitrification automaton, includes a nitrator, nitrator built with agitating device, at the top of nitrator
Motor is installed, bottom passes through the pipeline communication pump housing, it is characterised in that a level sensing is provided with the left of described nitrator
Device, right side are provided with a temperature sensor, and wherein liquid level sensor, temperature sensor and motor is all connected with controller；It is described
Controller in liquid level warning module and temperature alarming module are installed；The described pump housing is connected with pump housing activate switch, the pump housing
Activate switch connects controller.
In such scheme, described motor is servomotor, and the control of the controlled device of motor is started or closed, electric
Heat ray filter is installed between machine and nitrator.
In such scheme, described agitating device includes a main shaft and the stirring vane on main shaft, stirs
It is horizontally disposed to mix blade, and equidistantly distribute on main shaft, and stirring vane is shaped as banding.
This utility model is had the advantages that as a result of above-mentioned technical proposal：
This utility model simple structure, can be stirred automatically according to the change of temperature and liquid level, reduce energy resource consumption,
Improve production efficiency, reduces security risk.
