Background technology
Aminating reaction still is a kind of common chemical industry equipment, is the capital equipment in field of medicine and chemical technology ammonification operation.After aminating reaction terminates, need ammonia complete for unreacted in reactor to discharge, to ensure product quality.After current aminating reaction terminates, the method of discharging ammonia in reactor in reactor, accesses a nitrogen pipeline at the top of aminating reaction still, this nitrogen pipeline extends to bottom reactor along reactor inwall, pressurized nitrogen is utilized to be displaced by ammonia complete for unreacted in reactor, but because nitrogen bias current is uneven, ammonia is discharged completely needs 7-8 hour, and nitrogen consumption is large, expend time in length, and greatly reduce the production capacity of equipment.Chinese invention patent CN203620624U discloses a kind of gas distributor and uses the gas liquid reaction still of this gas distributor, and it is primarily of air inlet pipe and gas distribution pipe composition.Gas distribution pipe is made up of the qi-emitting hole according to the tactic several different pore size of pore size, ensures that multi-faceted the continuing of gas enters kettle, realizes gas uniform distribution.This distributor is arranged in the middle part of reactor, there is following point: 1. reactor bottom space becomes dead band (gas phase is easily bubbling effusion above at middle part); 2. distributor is not easy to install and maintenance in the middle part of paddle; 3., after this distributor is installed, blade can only be arranged on bottom still, and namely reactor can only install one deck blade; 4. affect mixing or the separative efficiency of reactor.In addition, this gas liquid reaction still cannot solve the problem that in ammonification operation, ammonia is discharged.
Summary of the invention
Object of the present invention will solve current ammonification operation exactly, and to terminate ammonia efflux time in rear reactor long, and nitrogen consumption is large, and does not have the problem of suitable ammonia excretion device of air in existing gas liquid reaction still, provides a kind of aminating reaction still that can reclaim ammonia fast.
Technical scheme of the present invention is: a kind of aminating reaction still that can reclaim ammonia fast, there is reactor body, the kettle outer wall of reactor is provided with chuck, agitating device is provided with in reactor, the top of reactor is provided with charging aperture, gas outlet and Pressure gauge, discharging opening is provided with bottom reactor, the external device for recovering tail gas in gas outlet at described reactor top, particularly: the distance bottom the stirrer bottom of described agitating device and reactor is 10 ~ 20cm, an annular gas distributor is equipped with in the below being positioned at agitator in Polycondensation Reactor and Esterification Reactor portion, a nitrogen tube is equipped with at reactor top, nitrogen tube extends along reactor inwall and is communicated with the gas access of annular gas distributor at the bottom of still, described annular gas distributor is made up of four sections of end to end arc tubes, the middle part of every section of arc tube is arranged on bottom reactor by clip, the top of every section of arc tube has several uniform apertures, the external nitrogen storage tank of described nitrogen tube.
Nitrogen tube described in the present invention and annular gas distributor are made by DN25 stainless steel tube.
Hole diameter on arc tube described in the present invention is 2mm, and the spacing between two between aperture is 2mm.
Agitator described in the present invention is any one in anchor agitator or arm stirrer or gate stirrer or helix(ribbon type) agitator.
Agitator on agitating device described in the present invention is one deck or two-layer.
The course of work of the present invention is: first in ammoniation kettle, add material and ammoniacal liquor carries out aminating reaction, after question response terminates, open the valve on nitrogen pipeline and tail gas recycle pipeline, nitrogen is made to enter the annular gas distributor bottom reactor by nitrogen tube, evenly flowed in the liquid phase of reactor by the aperture on annular gas distributor again, by ammonia air lift complete for unreacted in liquid phase out, nitrogen and the complete ammonia of unreacted reclaim ammonia by the gas outlet at reactor top through device for recovering tail gas.
The invention has the advantages that:
1. gas distributor is designed to annular, and designs uniform aperture on annular gas distributor, the nitrogen air flow method passing into reactor can be made so even, save evacuation time;
2. be four sections of end to end arc sections by annular gas distributor designs, utilize clip to be arranged on bottom reactor, design is conveniently installed and overhauls like this, once gas distributor breaks down, only needs the pipeline broken down to replace;
3. below agitator annular gas distributor being contained in reactor, make not exist in reactor the dead band that nitrogen can not arrive like this, thus ensure that in reactor, unreacted ammonia can thoroughly be discharged, do not affect the mixing effect of agitating device simultaneously, and make the agitator number of plies of agitating device unrestricted, it is more reasonable to design;
4. substantially reduce the recovery time of ammonia, existing aminating reaction still air lift ammonia needs 7-8 hour, and utilize aminating reaction still of the present invention, air lift ammonia only needs 3-4 hour, has not only saved nitrogen use level, also substantially increases the production capacity of equipment.
Structure of the present invention is simple, designs ingenious, and installation, maintenance is convenient, substantially increases the recovery speed of aminating reaction still ammonia after the completion of reaction, has saved the use amount of nitrogen, improve the production capacity of equipment; Certain the present invention is not limited in ammonification operation and uses, and also can be widely used in the chemical industry operation of gas liquid reaction.
