Abstract
The utility model discloses a low bromide epoxy resin reaction kettle system, which comprises a reaction kettle, and further comprises an evacuating device and a nitrogen filling device, wherein the evacuating device is arranged on one side of the reaction kettle through a vacuum valve, and the nitrogen filling device is arranged on the other side of the reaction kettle. Because the low bromide epoxy resin reaction kettle system is provided with the evacuating device and the nitrogen filling device, the low bromide epoxy resin reaction kettle system reduces oxygen content in the reaction kettle by evacuating before the reaction kettle feeds, reduces air which enters the reaction kettle by filling nitrogen to break vacuum before feeding, enables the inner portion of the reaction kettle to be kept in a state without oxygen by evacuating again when warming up, and guarantees low bromide epoxy resin not to be oxidized by external air, thereby guaranteeing product quality.
Description
Technical field
The utility model relates to a kind of reactor system, belongs to the chemical industry equipment field, is in particular a kind of low bromine Resins, epoxy reactor system.
Background technology
Oxidation chemically is being called oxygenizement, and traditional definition is material and combination with oxygen, forms the process of oxide compound, namely by the process of " oxygen " oxidation.Oxidation is a kind of important unit processes in chemical synthesis, occupies very important status simultaneously in chemical industry production.Yet in the reaction of some Chemical Manufacture, entering but of oxygen is harmful to, and can affect the color and luster, purity of product etc.Carry out easily being oxidized by oxygen in the reaction process at reactor at low bromine Resins, epoxy in the prior art, make the partially yellow quality product that affects of low bromine Resins, epoxy color of generation.Also fail to accomplish to keep to be in the reactor almost anaerobic state even taked to prevent the measure of product oxidation.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of reactor space that can make near vacuum, prevents the low bromine Resins, epoxy reactor system that low bromine Resins, epoxy finished product is oxidized.
For reaching above-mentioned technical purpose, the utility model is achieved through the following technical solutions:
A kind of low bromine Resins, epoxy reactor of the present utility model system, it comprises reactor, also comprises vacuum extractor and nitrogen charging device, and described vacuum extractor is installed in a side of reactor by vacuum valve, and nitrogen charging device is installed in the opposite side of reactor.
Further, described vacuum extractor mainly comprises vacuum tank and vacuum pump.
Further, be connected for stainless-steel pipe between described reactor and the vacuum extractor.
Further of the present utility model, described nitrogen charging device lower end, the offside that is connected with reactor is equipped with manhole.
Compared with prior art, the beneficial effects of the utility model:
The utility model structurally provides vacuum extractor and nitrogen charging device, reactor is before feeding intake, vacuumize and reduce oxygen content in the reactor, enter reactor by filling nitrogen vacuum breaker minimizing air before feeding intake, keep anaerobic state in the reactor by again vacuumizing to make during intensification, guarantee low bromine Resins, epoxy not by the oxidation of external airborne oxygen institute, thereby guarantee the quality of product.

Fig. 1 is structural representation of the present utility model.
Among the figure: 1, reactor; 2, vacuum extractor; 3, nitrogen charging device; 4, stainless-steel pipe; 5, nitrogen system; 6, the gas processing system that truncates; 11,12, variable valve; 21, vacuum tank; 22, vacuum pump; 23, vacuum valve; 24, vacuum meter; 31, control valve; 32, nitrogen inlet; 33, manhole; 34, nitrogen outlet; 35, variable valve
Embodiment
As shown in Figure 1, low bromine Resins, epoxy reactor described in the utility model system, it comprises reactor 1, vacuum extractor 2 and nitrogen charging device 3, described vacuum extractor 2 is connected to a side of reactor 1 by the stainless-steel pipe 4 that vacuum valve 23 is installed, described nitrogen charging device 3 is connected to the opposite side of this reactor 1.Wherein said vacuum extractor 2 mainly comprises vacuum tank 21 and vacuum pump 22.Described vacuum pump 22 1 ends are connected with this vacuum tank 21, and the other end is connected to the gas processing system 6 that truncates.Wire proximal response still 1 end of described vacuum extractor 2 is equipped with variable valve 12, and similarly, nearly this reactor 1 end of the wire of described nitrogen charging device 3 also is equipped with variable valve 11.
The nitrogen of described nitrogen charging device 3 derives from nitrogen system 5, enters from nitrogen inlet 32, and its uninterrupted is regulated by variable valve 35.For guarantee nitrogen evenly guarantor's amount enter this reactor 1, at nitrogen outlet 34 places of described nitrogen charging device 3 control valve 31 is installed.Described nitrogen charging device 3 lower ends, the offside that is connected with described reactor 1 is equipped with manhole 33, uses when being used for overhaul of the equipments.
Fill the nitrogen vacuum breaker is the normal means of using of Chemical Industry Drying apparatus field always, and the boiling point of solvent can reduce under the vacuum state, can faster dry product.And reactor 1 is before feeding intake in the utility model, and the vacuum pump 22 by vacuum extractor 2 vacuumizes, and can reduce reactor 1 interior oxygen content.Yet the reactor 1 under vacuum state can't be uncapped and be fed intake, and nitrogen is rare gas element, can not react with material, can drain oxygen and prevent that extraneous gas from entering simultaneously, therefore selects fill the nitrogen vacuum breaker by nitrogen charging device 3 this moment.Then heat up to feeding intake, again vacuumize by vacuum extractor 2, until vacuum meter 24 registrations be-95Kpa about, keep this vacuum tightness until reaction finishes.By vacuumizing, the nitrogen vacuum breaker vacuumizes after the rear intensification that feeds intake again, allows all the time reactor 1 interior maintenance anaerobic state, assurance hang down bromine Resins, epoxy not by the oxidation of the institute of the oxygen in the extraneous air, reaches the purpose that guarantees quality product.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
