Abstract
The utility model relates to an urotropine mother liquor circulating device which comprises a reaction kettle, a crystallization separation tank connected with the bottom of the reaction kettle and a circulating pump connected with the crystallization separation tank. The circulating pump is connected back to the reaction kettle through a pipeline. The pipeline between the circulating pump and the reaction kettle is provided with a water cooling device. The urotropine mother liquor circulating device has the beneficial effects that by the mother liquor circulating device, the temperature of circulating mother liquor can be reduced; and after the circulating mother liquor is subjected to convection with mother liquor in the reaction kettle, not only is the continuous and stable production facilitated, but also the requirement for increasing a productive task can be met.
Description
Technical field
The utility model relates to the urotropine production field, particularly relates to a kind of urotropine Recycling Mother Solution device.
Background technology
Urotropine is a kind of important chemical product, can be used as the solidifying agent of phenoplast, the catalyzer of aminoplastics, the promotor of the vulcanization of rubber; Industrial at other, can be used as the sanforzing agent of textile production, the sanitas of food-processing, diuretic(s) pharmaceutically; After the nitration treatment a kind of important powerful explosive; Can be used as sterilant on the agricultural again, also can be used as the phosgene absorption agent of smoke mask etc.
The industrially preparing process of urotropine is liquid phase method and vapor phase process.What suitability for industrialized production was commonly used is vapor phase process, vapor phase process is that ammonia and formaldehyde gas enter reactor together, generate urotropine with the circulating mother liquor generation condensation reaction in the still, the urotropine mother liquor that generates is through concentrated, crystallization, separation, wet urotropine after the separation obtains urotropine finished product and packing warehouse-in by air stream drying, and isolated mother liquor returns recycle in the reactor again.
It is a kind of thermopositive reaction that ammonia and formaldehyde solid/liquid/gas reactions are produced urotropine, can steady and continuous carry out in order to guarantee to produce, the urotropine reactor adopts the interlayer water quench, and the mother liquor temperature that loops back reactor is higher, be unfavorable for that urotropine is synthetic, influence is produced stable.
The utility model content
The purpose of this utility model is that a kind of urotropine Recycling Mother Solution device that can reduce the circulating mother liquor temperature will be provided.
In order to achieve the above object, the technical solution of the utility model is: a kind of urotropine Recycling Mother Solution device, comprise reactor, the Crystallization Separation groove that is connected with the reactor bottom, the recycle pump that is connected with the Crystallization Separation groove, recycle pump is provided with a water-cooled water cooler by the pipeline reactor that is linked back on the pipeline between recycle pump and the reactor.
The beneficial effects of the utility model are: this Recycling Mother Solution device can reduce the circulating mother liquor temperature, after mother liquor convection current in the reactor, not only helps producing continous-stable and carries out, and can satisfy the needs that strengthen production task.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of urotropine Recycling Mother Solution device, comprise reactor 1, the Crystallization Separation groove 2 that is connected with reactor 1 bottom, the recycle pump 3 that is connected with Crystallization Separation groove 2, recycle pump 3 is provided with a water-cooled water cooler 4 by the pipeline reactor 1 that is linked back on the pipeline between recycle pump 3 and the reactor 1.This Recycling Mother Solution device can reduce the circulating mother liquor temperature, after mother liquor convection current in the reactor 1, not only helps producing continous-stable and carries out, and can satisfy the needs that strengthen production task.
