Description
Technical field
The utility model relates to a kind of reactor, particularly relates to a kind of reactor with Novel spraying materials device.
Background technology
PPG synthesis technique mainly contains two kinds: one is merely in a kettle., adopts and stirs synthesis.Simultaneously another kind is also equipped with Matter Transfer pump in reactor, allows material circulate up and down at reactor.
Synthesizing polyether glycol is stirred in simple employing, and the reaction time is very long, and efficiency is low, simultaneously because mixed effect is not good, and the poor quality of product.Adopt and stir additional Matter Transfer pump, production efficiency improves greatly, simultaneously good product quality.In the process that material is circulated by material outside circulation pump, reactor squeezed into by material form from reactor upper end is very important.
Mode conventional at present has: material is directly squeezed in reactor by a steel pipe; Be by the special shower nozzle of specialty, allow material spray and enter in reactor.PPG reaction comprises gas liquid reaction and reactive liquid solution two processes.Two courses of reaction are reacted in equilibrium, best to product quality.By the form that material outside circulation pump circulates, there is gas-liquid mixed weak effect, only can play the upper and lower mixing of material, such PPG generated time is oversize, and efficiency is too low, and quality is also bad simultaneously.By the nozzle type that specialty is special, gas-liquid mixed effect is very good, reaction major part is completed in the process of gas-liquid contact, is unfavorable for the control of product quality.
Utility model content
The purpose of this utility model is the defect overcoming above-mentioned prior art, provides a kind of reaction that can balance gas-liquid and liquid-liquid diphase, the fast and reactor with Novel spraying materials device for PPG synthesis that product quality is high of reaction rate.
For this reason, the utility model provides a kind of reactor with Novel spraying materials device for PPG synthesis, comprises kettle, described kettle top is provided with motor, be provided with shaft in kettle, shaft is provided with paddle, the output shaft of described motor is connected with shaft; The upper and lower part of described kettle is provided with upper cycling mouth and lower circulation port, and the arranged outside of kettle has circulating pump, and described upper cycling mouth, circulating pump are connected by pipeline successively with lower circulation port;
Top in described kettle is provided with material-spraying device, and described material-spraying device is the pipeline connection of ring pipe, ring pipe and upper cycling mouth; Described ring pipe is horizontally disposed with, and the bottom of ring pipe is provided with multiple material spraying hole.Material enters in ring pipe by circulating pump, is injected in reactor by the material spraying hole bottom ring pipe, and material presents material spray atomizing effect.Make vapour-liquid good mixing effect, shorten the reaction time, improve production efficiency.
Described ring pipe is connected by the pipeline of reducer tee with upper cycling mouth place.
Described material spraying hole is distributed on the bottom of ring pipe and equal and opposite in direction.
The beneficial effects of the utility model: this reactor with Novel spraying materials device for PPG synthesis that the utility model provides, shaft is adopted to stir, and by the material spraying hole on ring pipe, material is sprayed in reactor, make to present material spray atomizing effect during material self-loopa, vapour-liquid mixes, shorten the reaction time, improve product quality and production efficiency.
