Meanwhile, because the utility model is provided with a chlorine gas recovering pipeline, the recovery rate of the chlorine gas can be raised, the environmental pollution can also be reduced, the utility model can continuously product for a long time, and the purposes of energy saving, high production and high efficiency can be reached.

Description

Electrolyzer

The utility model relates to a kind of fused salt electrolyzer, particularly produces the electrolyzer that rare earth metal or its alloy are used.

At present, produce the electrolyzer of rare earth metal with fused salt electrolysis process, adopt a vertical tubular plumbago crucible of placing to make anode, bar-shaped molybdenum system negative electrode is arranged on the tubular anode axis and inserts ionogen downwards, and the metal susceptor places negative electrode below crucible bottom central authorities.The major advantage of this traditional electrolyzer is simple in structure, and electric force lines distribution is even, can add the electrolysis of water-containing crystal material.Shortcoming is because structural limitations, and received current is little, yield poorly; The bath voltage height, heat radiation is serious, electrothermal efficiency is low; Open wide because crucible is suitable for reading, outside air easily is involved in ionogen and heat loss through radiation is big; Because the chlorine that the chloride system electrolysis produces does not well reclaim, and cause the waste of severe environmental pollution and chlorine resource, and the structure of emptying or recovery system is huge, consumption of power is also many; Because dehydration of crystallization material and electrolytic process carry out in same container, the hydrolysis body refuse amount of formation is big; And moisture content have been accelerated the oxidation of electrolytical consumption and rare earth metal, and have been aggravated the anodic oxidation loss by electrolysis in a large number, and the two all makes current efficiency and metal recovery rate reduce; Owing to must heat up earlier when going out metal, stop electrolysis then and take out metal, reduced effective electrolysis time; When plumbago crucible is lost to seepage, general about 10 days of life-span, must stop groove cooling earlier, also need reset after changing new electrolyzer, this process has not only reduced the rate of load condensate of direct supply, and will waste a large amount of energy.

The purpose of this utility model is to provide a kind of can increase substantially received current and electrothermal efficiency, and discharge material crystal water rapidly and structurally can avoid of the influence of material crystal water effectively electrolytic process, and continuous production for a long time is to reach energy-conservation, highly efficient and productive electrolyzer.

The purpose of this utility model also further provides a kind of electrolysis and reclaim the electrolyzer of chlorine easily under air-tight state.

The purpose of this utility model is implemented by following technical scheme: it is made up of cell body, container, in container, be provided with the anode block of 2 above vertical through hole, wherein anode block hole is a charge cavity, in other anode block hole the cathode bar of downward insertion is arranged and become the electrolysis hole, like this, just constitute an electrolysis mechanism that identical function is arranged with traditional electrolyzer, several electrolysis hole is arranged, with regard to the phase group several traditional electrolyzers are installed in parallel in a groove, several times of the corresponding increases of received current and output, and the cell body thermosteresis reduces when installing than independent electrolysis hole at double.Add the crystallization material from charge cavity, crystallization material instant dehydration in fused salt, steam is from charge cavity rapid discharge naturally suitable for reading.Charge cavity and electrolysis hole end opening are immersed in below the electrolyte levels, and constitute a connection container with the container bottom space, and electrolytical Circulation has guaranteed the homogeneity of ionogen composition and temperature in charge cavity and the electrolysis hole.

Added the groove lid of sealing and insulation effect on the cell body, the groove lid covers container top, and charge cavity passes the groove lid, and electrolysis hole and charge cavity are worked in coordination by groove lid seam and charge cavity top seam and kept apart on liquid level.Each electrolysis hole interconnects more than electrolyte levels, and is closed by the groove cap seal and to constitute an enclosed space.

On cell body top, groove lid bottom has a chlorine pipeline one end to lead to container, and the other end leads to the chlorine recovery system.Thereby avoided sneaking into of outside air and raw material moisture content, guaranteed the concentration of output chlorine and be convenient to reclaim, the structure and the power consumption of recovery system also so greatly reduce.

The utility model has the advantages that: increase substantially received current and electrothermal efficiency, and discharge material crystal water rapidly and structurally can avoid of the influence of material crystal water effectively electrolytic process, simultaneously, because the chlorine of recovery pipeline is arranged, improve the rate of recovery of chlorine, and also reduced environmental pollution, and continuous production for a long time, to reach energy-conservation, highly efficient and productive purpose.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a longitudinal diagram of the present utility model.

Fig. 2 is a vertical view of the present utility model.

As shown in Figure 1 and Figure 2, electrolyzer is made up of cell body 1, container 2, in container 2, be provided with the anode block of 7 vertical through hole, wherein the interstitial hole of anode block is a charge cavity 3, in other 6 anode block holes the cathode bar 4 of downward insertion is arranged and become electrolysis hole 5, like this, just constitute an electrolysis mechanism that identical function is arranged with traditional electrolyzer, several electrolysis hole 5 is arranged, just be equivalent to several traditional electrolyzers are installed in parallel in a cell body 1, several times of the corresponding increases of received current and output, and cell body 1 thermosteresis reduces when installing than independent electrolysis hole at double.Add the crystallization material from charge cavity 3, crystallization material instant dehydration in fused salt, steam is from charge cavity 3 rapid discharges naturally suitable for reading.Charge cavity 3 and electrolysis hole 5 end openings are immersed in below the electrolyte levels, and constitute a connection container with container 2 bottom spaces, and electrolytical Circulation has guaranteed the homogeneity of ionogen composition and temperature in charge cavity 3 and the electrolysis hole 5.Because to electrolysis hole 5, the migration way of moisture content lengthening, the moisture content that raw material is deviate from have not promptly generated the bubble floating discharge before reaching electrolysis hole 5, have blocked migration of water to electrolysis hole effectively and have participated in electrolysis from charge cavity 3.The increase of anode surface area has also increased the carburizing chlorination reaction probability of hydrolysate, has reduced the generation of body refuse.Molybdenum system ring groove shape metal vessel is placed in container 2 bottoms, and is led to outside the cell body 1 by liquid discharging tube, can emit metal when normal electrolysis.When the anode block oxidation loss in electrolysis hole 5 when influencing normal electrolysis, can change a new anode block and just can recover normal electrolysis, thereby reach long-term quantity-produced purpose.

Added the groove lid 6 of sealing and insulation effect on the cell body 1, groove lid 6 covers container 2 tops, and charge cavity 3 passes groove lid 6, is worked in coordination by groove lid seam 7 and charge cavity 3 top seams 8 with charge cavity 3 and keep apart on liquid level in electrolysis hole 5.Each electrolysis hole interconnects more than electrolyte levels, and constitutes an enclosed space by 6 sealings of groove lid.

On cell body 1 top, groove covers 6 bottoms has a chlorine pipeline 9 one ends to lead to container 2, and the other end leads to the chlorine recovery system.Thereby avoided sneaking into of outside air and raw material moisture content, guaranteed the concentration of output chlorine and be convenient to reclaim, the structure and the power consumption of recovery system also so greatly reduce.
