Description
Technical field
The present invention relates to the reactor preparing iron oxide black preparing ferrum in a kind of inorganic pigment iron oxide black production system, be specifically related to prepare the gas-liquid-solid phase reaction device of iron oxide black.
Background technology
Ferrum oxide is important inorganic chemistry pigment, and iron oxide black is one more typically, is widely used in the fields such as coating, building and traffic.At present, the production method of iron oxide pigment includes dry and wet.Producing substantial amounts of waste gas in dry production process, environmental pollution is more serious, it does not have practical in a large number；Wet method is current industrial commonly used method, manufactures in the production technology of ferrum oxide in wet method, it is common to adopt cylindric retort to react.Reaction raw materials copperas solution adds in retort, adds sodium hydroxide solution and regulates pH value, at a certain temperature, air is passed into bottom retort, and be stirred continuously so as to react, it is gradually added iron filings and participates in reaction, until mill base reaches required state in retort.Now, so as to react, reaction material is pumped into filter element, after through washing.Dry and packaging, be finished product.
Wet Method Reaction produces in the process of iron oxides inorganic pigment, and reaction efficiency and product quality are had important impact by the mixability of gas-liquid-solid three-phase.Only gas-liquid-solid is fully contacted, and can be only achieved the consumption that economizes in raw materials, and improves the purpose of efficiency and product quality.Along with yield and the demand of iron oxide black constantly increase, newly-built iron black project tonnage is all relatively big, thus therefore the volume of the retort adopted also raises.In the case, in gas-liquid-solid phase reaction device, gas-liquid-solid Flow Field Distribution is particularly important, design unreasonable will result in and react dead angle, cause that reactor effective reacting volume reduces, reaction efficiency declines and product particle skewness, product quality declines, and report disclosed at present rarely has the design preparing iron oxide black reactor, such as patent of invention " Processes and apparatus of wet method manufacture iron oxide black " (CN1143049A) discloses the production technology of a kind of iron oxide black, but requires simpler to consersion unit.Along with the increase of retort, there is some problems in gas-liquid-solid three-phase mass transfer, it is necessary to carries out appropriate design.
Summary of the invention
It is an object of the invention to provide and a kind of novel, practical prepare iron oxide black reactor with air secondary distribution, to substitute traditional iron black reaction container, realize improving retort effective rate of utilization, improve the uniformity of finished powder, improve conforming product rate, reduce energy consumption.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of reactor preparing iron oxide black, it is characterised in that be made up of retort 3, frequency conversion motor 1, main shaft 2, tapered air distribution grid 4, fixing device the 5, first stirring paddle 6A, the first stirring paddle 6B, heating coil 7, aeration plate 8, blowdown interface 9 and thermometer 10；Wherein retort 3 top center is provided with frequency conversion motor 1, frequency conversion motor 1 connects main shaft 2, main shaft about 2 is separately installed with the first stirring paddle 6A and the second stirring paddle 6B, tapered air distribution grid 4 is fixed on the inwall of retort 3 by fixing device 5 and its height is in the middle of the first stirring paddle 6A and the second stirring paddle 6B, equipped with aeration plate 8 bottom retort 3, heating coil 7 is positioned at above aeration plate 8, second stirring paddle 6B is positioned at above heating coil 7, first stirring paddle 6A is positioned at the middle and upper part of retort 3, retort 3 side is installed below blowdown interface 9, thermometer 10 is installed on middle and upper part, retort 3 side.
Utilize Frequency Converter Control frequency conversion motor to realize different stir speed (S.S.), control the liquid mixing uniformity in retort；Bottom aeration plate passes into reaction required air, and it is uniform by twice dispersing that air rises to tapered air distribution grid place.
Preferred described tapered air distribution grid be big mouth upper, osculum under configuration；Described tapered air distribution grid 4 is perforated panel, is uniformly distributed the hole of circular hole, square hole or other shapes；The area in each hole is 1-100cm2；Hole number on every square metre of tapered air distribution grid is 80-5000；The material of preferred dispersion plate is plastics or rustless steel, it is possible to so that the material of other alkali corrosion resistances.
Reaction raw materials copperas solution adds in retort, it is subsequently adding sodium hydroxide solution and regulates ph value, heating coil passes into steam, it is generally heated to 75-90 degree, bottom retort, passes into air, start frequency conversion motor and drive stirring paddle Stirring, the air that aeration plate enters bottom retort enters retort top after tapered air distribution grid, in retort, reaction mass is sufficiently mixed, until when in retort, mill base reaches required state, stopped reaction.
Accompanying drawing explanation
Fig. 1 is that the present invention is for preparing the structural representation of the reactor of iron oxide black, wherein 1, frequency conversion motor, 2, main shaft, 3, retort, 4, tapered air distribution grid, 5, fixing device, 6A, the first stirring paddle, 6B, the second stirring paddle, 7, heating coil, 8, aeration plate, 9, blowdown interface, 10, thermometer.
