Technical field
The utility model relates to polycarbonate production field, particularly relates to a kind of polycarbonate production device.
Background technology
In polycarbonate production device, finally all need the unnecessary volatile matter that removes in polycarbonate and add some auxiliary agents.In prior art, devolatilization extruder can realize this two objects, although devolatilization extruder energy effective elimination volatile matter, but the reason owing to itself constructing, be difficult to arrive the resistance to air loss requirement of poly-unit, easily cause air impact in reactive system of bleeding react and bring potential safety hazard.Moreover, large-scale devolatilization extruder and auxiliary auxiliary agent add-on system cost of equipment costliness, investment is large, and equipment maintenance is comparatively difficult.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of polycarbonate auxiliary agent to be added and the production equipment of devolatilization online.
For achieving the above object, the utility model provides following technical scheme: a kind of polycarbonate production device, comprise the feed-pipe that inside has polycarbonate melt, this feed-pipe is by being connected with the first devolatilizer after interchanger, the steam stripping agent add-on system for providing steam stripping agent is provided with between feed-pipe and interchanger, the downstream of this first devolatilizer connects the second devolatilizer, the outlet of the second devolatilizer is connected with melt Conveying pump, melt Conveying pump connects granulating system after connecting static mixer, also be connected with for providing the auxiliary agent increasing solidifiability auxiliary agent add-on system between this melt Conveying pump and static mixer, this first devolatilizer is provided with the first ventage and the first pressurize mouth, this second devolatilizer is provided with the second ventage and the second pressurize mouth.
The utility model is set to further: described first devolatilizer is also provided with the first liquid level sensor, between the first devolatilizer and the second devolatilizer, be provided with automatic regulating valve, and the aperture of this automatic regulating valve is controlled by the first liquid level sensor.
The utility model is set to further: described second devolatilizer is also provided with the second liquid level sensor, and the start and stop of described melt Conveying pump are controlled by the second liquid level sensor.
The utility model is set to further: described first ventage leads to nitrogen, and the air pressure inside of the first devolatilizer is 0.05mbar (a).
The utility model is set to further: described second ventage leads to nitrogen, and the air pressure inside of the second devolatilizer is 0.01mbar (a).
Compared with prior art, the utility model has the advantage of: not having churned mechanically devolatilizer to carry out devolatilization by using, significantly reducing the risk of leakage; Online interpolation auxiliary agent is also mixed with polycarbonate melt by static mixer; Whole planning device investment is little, and there is not large-scale dynamic equipment, reduces the risk that routine maintenance requires and affects production because equipment goes wrong; Devolatilization extruder can be replaced completely to use in actual production.

Fig. 1 is the system diagram of a kind of polycarbonate production device of the utility model embodiment.
In figure, 1, up-stream system; 2, steam stripping agent add-on system; 3, interchanger; 4, the first devolatilizer; 41, the first inlet mouth; 42, the first pressurize mouth; 43, the first liquid level sensor; 5, automatic regulating valve; 6, the second devolatilizer; 61, the second inlet mouth; 62, the second pressurize mouth; 63, the second liquid level sensor; 7, melt Conveying pump; 8, auxiliary agent add-on system; 9, static mixer; 10, granulating system.
Embodiment
With reference to Fig. 1, the embodiment of a kind of polycarbonate production device of the utility model is described in further details.
The utility model polycarbonate melt enters interchanger 3, through interchanger 3 heat temperature raising 5-10 DEG C to reduce viscosity and to be conducive to next step devolatilization after mixing with the steam stripping agent from steam stripping agent add-on system 2 on feed-pipe after up-stream system 1 output.Then melt enters the first devolatilizer 4 melt and forms the bar with larger devolatilization surface by the distribution plate of the first devolatilizer 4 inside and fall into bottom the first devolatilizer 4, in this process, in the first devolatilizer 4, pass into nitrogen by the first inlet mouth 41, the vacuum system be connected with the first pressurize mouth 42 vacuumizes devolatilizer and makes the vacustat of system at 0.05mbar (a).Under the acting in conjunction on nitrogen and steam stripping agent and larger devolatilization surface, the volatile matter in melt is easily drawn out of.The melt fallen into bottom the first devolatilizer 4 can enter into the second devolatilizer 6.For ensureing to produce continuously, have automatic regulating valve 5 bottom the first devolatilizer 4, the aperture of automatic regulating valve 5 is controlled by the first liquid level sensor 43, to keep the level stability in the first devolatilizer 4.
Second devolatilizer 6 is identical with the first devolatilizer 4 structure, in the second devolatilizer 6, pass into nitrogen by the second inlet mouth 61, the vacuum system be connected with the second pressurize mouth 62 vacuumizes devolatilizer and makes the vacustat of system at 0.01mbar (a).
Melt after the second devolatilizer 6 devolatilization passes through melt pipe downstream transport by melt Conveying pump 7, export at melt Conveying pump 7 and in melt, add auxiliary agent by auxiliary agent add-on system 8, then through static mixer 9, granulating system 10 granulation after mixing, is entered.
Because a certain amount of material must be had bottom the second devolatilizer 6 to ensure that melt Conveying pump 7 can run well, so be provided with second liquid level sensor 63 bottom the second devolatilizer 6, when the level attitude of liquid level lower than the second liquid level sensor 63, second liquid level sensor 63 is triggered, transmission signal is to melt Conveying pump 7, and melt Conveying pump 7 shuts down.When liquid level is higher than the second liquid level sensor 7, melt Conveying pump 7 restarts.In system, all devices, pipeline all have chuck heating medium for heating.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
