Abstract
The utility model relates to an improvement for the equipment required by the carnallite magnesium refining manufacturing technique, particularly the improvement for the special equipment for dewatering the carnallite be fore the fine magnesium is refined. The utility model has the technical proposal that chlorination dewatering equipment is adopted to make the further dewatering, and chlorination on the dewatering carnallite which has been made with one-time dewatering to obtain the anhydrous carnallite. The chlorinating dewatering equipment adopts a melting electric stove to make the dewatering; through the protective atmosphere, the resultant gas pressure of the hydrolysis reaction in the process of dewatering is changed, and the hydrolysis is effectively suppressed. The anhydrous carnallite suitable for refining the magnesium of the modernized large-scale large-capacity electrolyzer can be obtained.
Description
The utility model relates to the improvement of carnallitite magnesium-smelting production technology required equipment, particularly relates to the improvement of the preceding Carnalite dehydration specific equipment of refining magnesium.
Traditional refining magnesium raw material is a giobertite, and in recent years, people have developed new refining magnesium approach, promptly adopts the abundant carnallitite resource refining magnesium in salt lake, and not only cost is lower than giobertite magnesium cost, and technology is simple, and quality product also increases.But contain a large amount of attached waters and crystal water in the carnallitite, can not directly be used for refining magnesium, the Carnalite dehydration problem is the problem that people put forth effort to study.
Conventional fixed-bed type dehydration equipment, because of it can't solve hydrolysis problem in the Carnalite dehydration process, can not suppress hydrolysis, also just can not obtain refining the required anhydrous carnallite of closing down magnesium electrolysis bath, therefore traditional dehydration equipment can not satisfy the processing request of refining magnesium with the dehydration carnallitite.
The purpose of this utility model provides a kind of secondary chlorination dehydration equipment that is used for Carnalite dehydration process, can not only effectively suppress hydrolysis, and can make through the carnallitite that contains 5% left and right sides moisture content after the primary dewatering after fusion chlorination dehydration, obtain anhydrous carnallite.
The purpose of this utility model be achieved in that a kind of carnallitite chlorination dehydration equipment chlorinator by the melting chamber that is used to melt the dehydration carnallitite, be used for the chlorination chambers of further heating and melting carnallitite and chloride oxidation magnesium and be used to accumulate and the clarifying chamber that clarifies melt forms, melting chamber is communicated with by overflow ducts with chlorination chambers, and chlorination chambers and clarifying chamber are by the channel connection that is located at chlorination chambers suspension type dividing plate lower end.
Because a kind of carnallitite chlorination of the utility model dehydration equipment has adopted the dehydration of fusion electric furnace; and in dehydration, increased protective atmosphere; changed the resultant air pressure of hydrolysis reaction in the dehydration; suppress hydrolysis effectively, thereby can obtain being suitable for the anhydrous carnallite that the extensive large vol electrolyzer of modernization uses.
Fig. 1 is a kind of carnallitite chlorination of the utility model dehydration equipment structural representation.
How further narrate the utility model below in conjunction with accompanying drawing realizes: a kind of carnallitite chlorination dehydration equipment chlorinator is made up of the melting chamber (1) that is used to melt the dehydration carnallitite, the clarifying chamber (7) that is used for the chlorination chambers (3) of further heating and melting carnallitite and chloride oxidation magnesium and is used to accumulate and clarify melt.Be communicated with by overflow ducts (11) between melting chamber (1) and the chlorination chambers (3), this overflow ducts (11) is located at the upper end of dividing plate between melting chamber (1) and the chlorination chambers (3); Between chlorination chambers (3) and clarifying chamber (7) by the channel connection of suspension type dividing plate (4) lower end that is located at chlorination chambers (3), between the suspension type dividing plate (4) of chlorination chambers (3) and clarifying chamber (7) partition wall cavity is arranged, there is an overflow ducts partition wall upper end in clarifying chamber (7); The upper end cover (12) of melting chamber (1) is provided with heating electrode (14), chlorination chambers (3) upper end cover (9) is provided with heating electrode (10), the bottom is provided with Chlorination tube (2), clarifying chamber (7) upper end cover is provided with heating electrode (8), around the inwall of melting chamber (1), be provided with graphite block (13), the outside, passage place, chlorination chambers (3) suspension type dividing plate (4) lower end is provided with a tilting graphite block (5), and clarifying chamber (7) bottom is provided with a tilting graphite block (6); Bottom in chlorination chambers (3) and clarifying chamber (7) is equipped with a slag notch.
A kind of carnallitite chlorination of the utility model dehydration equipment is work like this: chlorinator is made up of melting chamber, chlorination chambers and clarifying chamber's three parts, for making magnesium oxide chlorination more fully in chlorination chambers, before the carnallitite fusing, add the melting chamber that good refinery coke of fragmentation and primary dewatering carnallitite enter chlorinator together.The dehydration carnallitite feeds electric current by electrode and melts, and the melt after the fusing flows into chlorination chambers by overflow ducts.
Two electrifying electrodes on the chlorination chambers upper end cover make melt continue to heat up, and two Chlorination tubes of chlorination chambers bottom are supplied with chlorine.Chlorine is sent into chlorination chambers after the Chlorine Buffer Vessel decompression.Chlorine is sent into from the chlorination chambers bottom, and melt flows into from the upper end of the partition wall between melting chamber and chlorination chambers overflow port, and chlorine forms relative countercurrent movement with melt, and chlorine is maximally utilised.
Melt flows in the clarifying chamber of chlorinator from chlorination chambers by gravity flow, here makes and is suspended in the magnesium oxide that is not chlorinated in the melt, superfluous refinery coke and other solid impurity is able to clarify with melt extraction.Melt after the clarification is discharged by weif orifice, promptly obtains anhydrous carnallite, just can carry out electrolysis refining magnesium.
