Description

A kind of polypropylene agitated reactor
Technical field
The present invention relates to a kind of reactor, especially a kind of polypropylene agitated reactor.
Background technology
Reactor of the prior art is mostly for chemical field, stirs fully in a kettle. to chemical substance, but traditional reactor stirs abundant not, and mixing time is long, but poor effect, affect follow-up operation.Simultaneously for the chemical products needing successive reaction to prepare, the time of staying, stirring intensity, temperature etc. are very large on its impact, and along with people are to the requirement increasingly stringent of product purity, except material purity is required, also avoid introducing impurity in course of reaction as far as possible, and for the reactor of metal material, due to the corrosion of chemical raw material and the oxidation of air, inevitably introducing portion metal impurities, and the reactor price of metal material, processing and repairing difficulty.And polypropylene (PP) reactor is due to PP material stable chemical performance, there is very strong acid and alkali resistance, the characteristic of oxidation, avoids in course of reaction and introduce impurity.
Chinese patent CN2294107, open a kind of single slurry multiple-effect reactor, it is made up of reactor, anchor agitator, rotating shaft, be provided with in reactor on guide shell, guide shell and be connected with unidirectional baffle plate, the outer wall of reactor has chuck, the top of chuck is provided with annular water tank, and gap is arranged at the bottom of annular water tank.This reactor stirs insufficient, and mixing time is long.
Chinese patent 201020171131.3, discloses a kind of a kind of enhanced plastic reactor for chemical field.Comprise cylindrical shell and cover plate, cylindrical shell and cover plate match, and be provided with shaft and charging aperture, be provided with discharging opening in cylindrical shell in cover plate, and the outer wall of described cylindrical shell is coated with strip winding layer.Abundant reaction, raises the efficiency.But frame type agitating blade energy consumption is large, and stirring intensity is low.And there is no jacketed, be not suitable for isothermal reaction.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and the one that provides adopts polypropylene and the manufacture of PP material, cost is low and be convenient to maintenance, and stir, energy consumption is low, and the polypropylene agitated reactor of the constant temperature of realization response system.
In order to achieve the above object, the technical scheme that Bian of the present invention gets is:
A kind of polypropylene agitated reactor, comprises kettle, stirring system and chuck; Kettle comprises kettle cover, kettle cover is provided with manhole, peep hole, charging hole and thermocouple fixing hole, stirring system comprises stirring motor, paddle and electrical control cubicles, chuck comprises chuck chamber, inlet opening and apopore, it is characterized in that: kettle surrounding is provided with four pieces of baffle plates, bottom is provided with a baiting valve simultaneously, and kettle sidewall is provided with two overfalls, and described paddle is double-layer paddle.
Described kettle and chuck are PP material.
A kind of polypropylene agitated reactor designed by the present invention, kettle cover is provided with a manhole, clears up material and maintenance, be provided with a peep hole simultaneously under being convenient to people in reactor, is convenient to observe the response situation in still.Charging aperture divides equally the surrounding at still, and has a sheath to put in reactor, supports the charge pipe that charge pipe avoids the turbulent flow of solution to cause and rocks or fracture.Kettle cover is provided with a thermocouple hole simultaneously, also has a sheath to put in reactor, support the thermocouple probe that thermocouple probe avoids the turbulent flow of solution to cause and rock or fracture.Still wall has four pieces of baffle plates, for the middle-grade stream solution of course of reaction, make to mix between solution more abundant, sidewall has two overfalls one on the other, can carry out which overfall of free choice for use according to the time of staying of reaction and output.Stirring motor controls speed of agitator by electrical control cubicles, and reduce energy consumption, paddle is double-layer paddle, and stirring intensity is large, and mixing of materials is even.Chuck is used for constant reaction temperature, is entered by the water of steady temperature, go out from apopore from inlet opening, by the constant and control of the circulation realization response system temperature of water.
Advantage applies of the present invention is in the following aspects:
(1) whole kettle and chuck adopt the manufacture of PP material completely, cost low and be convenient to maintenance, avoid simultaneously product introduce metal impurities, be desirable anticorrosion consersion unit.
(2) arrange Double-layer stirring paddle, stirring intensity is large, and energy consumption is low, and efficiency is high.
(3) chuck is set, for the temperature of accurate constant reaction.
The present invention design equipment energy consumption little, cost is low, can realization response constant temperature, avoid introduce metal impurities, anticorrosion, have very large dissemination.
