Description
Technical field
The utility model relates to a kind of reactor that uses hydrochloric acid to decompose aluminium ore or other mineral, particularly a kind of breeze acidolysis reaction device of the extracorporeal circulation heating with triphase separator.Belong to the technical field that inorganic chemical industry is produced.
Background technology
In the prior art, breeze acidolysis reaction device generally mainly contains the reaction vessel of opening for feed, slip extraction mouth, be installed in motor and step-down gear on the reaction vessel top, an end fixedly connected with motor and speed reducer output shaft or be connected as a single entity, another section is positioned at reaction vessel, the lower end is connected with agitator formations such as main shaft.When using hydrochloric acid to decompose aluminium ore or other mineral, usually need to supply with suitable heat so that keep the temperature environment of reaction needed, but, the reactive system corrodibility of hydrochloric acid medium is very strong, if conversion unit also needs good heat transfer, the material problem is difficult to solve, and pre-existing reactors is difficult to be suitable for.The equipment of the most normal use at present is glassed steel reaction vessels, and the existing good heat transfer performance of glassed steel reaction vessels has good salt tolerant acid corrosion performance again, is a kind of more satisfactory conversion unit; But the volume size of existing glassed steel reaction vessels is generally smaller, can not adapt to the needs of scale operation, and simultaneously, the failure rate of lass lining conversion unit is than higher, and particularly under the situation of acidolysis breeze, reactor is often damaged easily.For the volume of reactor is enough big, have good salt tolerant acid corrosion performance simultaneously, reactor can adopt the equipment of non-metallic liner, and still, these non-metallic liner equipment are difficult to make the form of conducting heat by partition, and equipment is big more, and difficulty is big more.Because being the hydrochloric acid that is specifically designed to mineral substance, decomposes this reactor, certainly existing the resistates (slag) after a large amount of breezes and the breeze acidolysis in the reaction mass, therefore, realize that in this case in fact the pump circulation heat exchange is difficult to realize, because material viscosity height, the suspension content height must cause circulating line to stop up, denude serious and heat exchange efficiency is low, and production process can't be kept.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, carry out extracorporeal circulation heating etc. by setting " triphase separator ", use graphite heat exchanger, thereby the breeze acidolysis reaction device of the extracorporeal circulation heating of the good band triphase separator of a kind of result of use is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of breeze acidolysis reaction device of the extracorporeal circulation heating with triphase separator, comprise: have opening for feed, slip to extract the reaction vessel of mouth out, motor and the step-down gear (motor and speed reducer of passable connection, it also can be the motor of band step-down gear, same prior art), one end fixedly connected with motor and speed reducer output shaft or be connected as a single entity, another section is positioned at reaction vessel, the lower end is connected with agitator main shaft, it is characterized in that also comprising:
A triphase separator, this triphase separator by with the housing (2) that fixedlys connected in described reaction vessel (4) top, hypomere is back taper annulus (14), the reflux exchanger (12) that be arranged at housing (2) top, is connected with housing (2), and a drain pipe (15) that is connected with housing (2) constitutes;
The graphite heat exchanger (8) that a circulation fluid liquid-inlet pipe (8) that is positioned at reaction vessel (4) bottom and is connected with reaction vessel (4), one one end are communicated with drain pipe (15), the other end is communicated with circulation fluid liquid-inlet pipe (8) by slurry circulation pump (6), vacuum breaker (7).
Described motor and step-down gear (1) are installed on the top of housing (2) and described main shaft (3) passes housing (2).
In the technical solution of the utility model: can be provided with phenolic fiberglass reinforced plastics internal layer, graphite brick internal layer, inner polytetrafluoroethyllayer layer or acid-proof ceramic tile internal layer on described reaction vessel (4) inwall.
In the technical solution of the utility model: can also be fixedly connected with taper centrifugal thrust (11) on the main shaft (3) of described housing (2) below
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) the utility model adopts the housing, reflux exchanger, drain pipe etc. that are the back taper annulus by hypomere to constitute, and has " triphase separator " of solid, liquid, gas separation function; When being used for hydrochloric acid decomposition aluminium ore or other breezes, the solid particulate that " triphase separator " suspends the overwhelming majority mainly concentrates in " triphase separator " following conversion zone, on a small quantity along with solution rises to the interior suspended solid in " triphase separator " zone, gravity settling takes place because flow velocity reduces, the tapered slope of back taper annulus comes back to conversion zone in " triphase separator ", and what accumulate in " triphase separator " internal space is clear liquid completely basically.Therefore, leave " triphase separator " and be substantially devoid of suspended solid from the solution that drain pipe enters graphite heat exchanger, can successfully realize the heat exchange circulation, the abrasion and the obstruction of equipment are effectively eliminated; Reclaim hydrochloric acid by the reflux exchanger that is installed in the triphase separator top, the hydrochloric acid vapour that produces in the reaction is effectively separated with liquid phase with other gases; Because the existence of " triphase separator ", the gentle zone that is separated of conversion zone has been isolated by the fluid-tight effect of the circulating liquid in " triphase separator " internal space, make that the reaction of hydrochloric acid is more abundant, vaporization losses significantly reduces, and has improved reaction effect;
(2) the utility model adopts graphite heat exchanger, will carry out external pump circulation heat exchange from " triphase separator " interior isolating clear liquid, like this, has both replenished the heat that reactive system needs, and utilizes the circulation thrust of pump to play the violent stirring effect again; Because recycle stock is through the clear liquid after " triphase separator " separate solid suspended substance, so the obstruction of graphite heat exchanger, wearing and tearing or the like problem is eliminated, and has guaranteed the reliability service of equipment;
(3) owing to can realize the extracorporeal circulation heating smoothly, therefore, the conversion unit body no longer needs heat exchange, can adopt non-metallic material inner liner (for example phenolic fiberglass reinforced plastics lining, graphite brick lining, teflon lined or acid-proof ceramic tile lining etc.), for the maximization and the reliability of conversion unit have been created good condition; And volume of equipment is big more, and the separating effect of " triphase separator " is good more;
(4) simple in structure, easy to manufacture, use easy to operate, effective, practical.
