The non-ideal product impurity generated is more), become the technological difficulties of production hydroxyethylhydrazine.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of micro-reaction equipment producing hydroxyethylhydrazine,
The device enables hydrazine hydrate to be come into full contact with ethylene oxide, improves reaction efficiency.
The utility model is realized in this way a kind of micro-reaction equipment producing hydroxyethylhydrazine, including mixing tube and anti-
It is U-tube to answer device, the mixing tube, and the both ends of mixing tube are connect with reactor lower part, and mixing tube lower part enters Guan Lian with hydrazine hydrate
It connects, hydrazine hydrate, which enters, is arranged preheating device on pipe, the both sides standpipe of mixing tube enters pipe with ethylene oxide respectively and connect, and ethylene oxide enters
Two ends of pipe connect nozzle, and nozzle is equipped with multidirectional spray-hole, and nozzle is down-set.
Further, mixing tube both sides standpipe is equipped with pigtail, and pigtail is arranged in the epoxy second
Alkane enters on the mixing tube both sides standpipe of pipe nozzle or more.
Further, spiral there are one being set on the pigtail.
Further, the hydrazine hydrate enters pipe and the ethylene oxide enters to be additionally provided with flowmeter on pipe.
Further, the junction that the both sides standpipe of the mixing tube enters pipe with the ethylene oxide is welding.
Compared with prior art, the utility model has the advantage of：Hydrazine hydrate passes through nozzle and spiral with ethylene oxide
The setting of pipeline section can be better mixed, and improve reaction efficiency, improve the yield of hydroxyethylhydrazine.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model：
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
With reference to figure 1, in order to improve the production reaction efficiency of hydroxyethylhydrazine in laboratory, the utility model provides a kind of life
Produce the micro-reaction equipment of hydroxyethylhydrazine, including mixing tube 1 and reactor 2, mixing tube 1 is U-tube, the both ends of mixing tube 1 with
2 lower part of reactor connects, and 1 lower part of mixing tube enters pipe 3 with hydrazine hydrate and connect, and hydrazine hydrate enters setting preheating device 4 on pipe 3, mixing
The both sides standpipe of pipe 1 enters pipe 5 with ethylene oxide and connect respectively, and ethylene oxide enters two ends connection nozzle 6 of pipe 5, on nozzle 6
Equipped with multidirectional spray-hole, in the multidirectional injection in same level direction, nozzle 6 is down-set, and positive direction is sealed condition.
Using the present apparatus produce hydroxyethylhydrazine when, hydrazine hydrate from lower part hydrazine hydrate enter pipe 3 by preheating device 4 preheat into
Enter, from the both sides standpipe uplink of mixing tube 1, liquid epoxy ethane enters pipe 5 from ethylene oxide and enters, from moment after the ejection of nozzle 6
Gasification, mixes with hydrazine hydrate, and hydrazine hydrate carries ethylene oxide and continues uplink, is further mixed in mixing tube 1, until entering
Into reactor 2, start subsequent reactions.
In order to extend the incorporation time of hydrazine hydrate and ethylene oxide, as the improvement of technical solution, 1 both sides standpipe of mixing tube
It is equipped with pigtail 11, and the mixing tube both sides standpipe for entering 6 or more pipe nozzle in the ethylene oxide is arranged in pigtail 11
On.
Preferably, being set on the pigtail 11, there are one spirals.
Because it is proportional that hydrazine hydrate generates hydroxyethylhydrazine with ethylene oxide, therefore, as the improvement of technical solution, institute
State that hydrazine hydrate enters pipe 3 and the ethylene oxide enters to be additionally provided with flowmeter 7 on pipe 5, flowmeter 7 is by both reaction ratio control stream
Amount.
As a kind of specific connection type, the junction that the both sides standpipe of mixing tube 1 enters pipe 5 with the ethylene oxide is
Welding.
