Description
Technical field
The utility model provides chemical field and is used for electrolysis clarifying smoke retrieving arrangement.
Background technology
In the electrolysis process production process, in electrolyzer, produce a large amount of flue dust and enter in operating environment and the atmosphere, environment is had destructiveness.Some useful dust materials together are discharged from simultaneously, have wasted raw material, have increased production cost.
For example: the fused salt electrolysis process of metal-rare-earth oxide compound normally adopts rare earth fluorine of the same race and low amount of fluorinated lithium to be dissolved in the villiaumite system by constantly adding rare earth oxide after high temperature melting as ionogen, electrolytic reaction takes place under certain voltage, current condition obtain rare earth metal.Also can obtain rare earth metal and non-rare earth alloys by changing the negative electrode material.In the electrolytic process of rare earth, the main gas that produces has CO, also has a small amount of LiF, ReF in addition
3, CF
4Deng.Because the bulk specific weight of rare earth oxide is less, particle is very thin, and the hot gas flow that constantly reinforced process must be subjected to the anode generation dashes band and enters surrounding space, thereby causes the loss of rare earth.Through existing electrolysis process material balance measuring and calculating, the utilization ratio of rare earth oxide is not more than 97%, and the LiF that while evaporation of metal per ton falls is about 7 kilograms.Above-mentioned flue dust is along with CO, CF
4Be difficult in the surrounding space administer and recycle Deng entering.
Summary of the invention
In order to overcome the drawback that existing electrolytic process flue dust freely discharges, the utility model proposes electrolysis clarifying smoke retrieving arrangement.This device is by being provided with collecting hood above electrolyzer, and is connected with the flue dust collecting device by the flue dust vent pipe and solves the technical problem that the electrolysis clarifying smoke reclaims.
The scheme that the utility model technical solution problem is adopted is: the both sides of process furnace are provided with carrying roller respectively, and electrolyzer is installed on carrying roller, and the bolster of electrolyzer is placed on the carrying roller, and can prolong carrying roller and slide.Negative electrode and anode are installed in electrolyzer and are provided with charging opening, upper edge at electrolyzer is equipped with collecting hood by the collecting hood slideway, be provided with the flue dust vent pipe above collecting hood, in the flue dust vent pipe amount adjusting valve be installed, the flue dust vent pipe is connected with the flue dust collecting device.
Positively effect is: the utility model is simple in structure, and reliable in action, and can reclaiming the clarifying smoke that produced in the electrolytic process obtain valuable material, saves, the consumption reduction effect is obvious.Reduce the electrolysis flue dust simultaneously to atmospheric pollution and improve the hazardness of operating environment.Suit to use in electrolysis clarifying smoke and the field of reclaiming useful matter.

Embodiment
According to shown in Figure 1, the both sides of process furnace 1 are provided with carrying roller 1.1 respectively, and electrolyzer 2 is installed on carrying roller, and the bolster 2.4 of electrolyzer is placed on the carrying roller, and can prolong carrying roller and slide.Negative electrode 2.1 and anode 2.2 are installed in electrolyzer and are provided with charging opening 2.3, upper edge at electrolyzer is equipped with collecting hood 3 by collecting hood slideway 3.1, above collecting hood, be provided with flue dust vent pipe 3.2, amount adjusting valve 3.3 is installed in the flue dust vent pipe, and the flue dust vent pipe is connected with flue dust collecting device 3.4.
The flue dust vent pipe can be connected with one or more flue dust collecting devices and carry out the purifying treatment of flue dust.But flue dust collecting device sack cleaner, electrostatic precipitator, wet scrubbing fly-ash separator or tornado dust collector.
Soot emissions speed can be adjusted by the amount adjusting valve that is located in the flue dust vent pipe.
When electrolyzer charging or repairing, can promote collecting hood and electrolyzer along sliding on electrolyzer upper limb and the carrying roller.Then slide to reset again and enter production status.
Use: the utility model in use, the flue dust that electrolytic tank electrolysis produced is discharged by the flue dust vent pipe, the flue dust vent pipe is connected with the flue dust collecting device, in order to the flue dust that is produced in the collection electrolytic process.And can collect useful material, continue on for the electrolysis raw material.Gas after the udst separation can directly enter atmosphere, thereby prevents that the electrolysis flue dust is to atmospheric pollution.
The example explanation:
1, be example to produce 14 tons of praseodymium neodymium alloy electrolysis systems per month, per hour the fume amount of Chu Liing is 30m
3, dust concentration is 13.9g/m
3, adopt sack cleaner to carry out treatment and purification, through one month operation, collect dust 280kg altogether, by analysis, dust is mainly ReF
3, LiF, Re
2O
3, the rate of recovery reaches 99%.
2, be example to produce 14 tons of neodymium metal electrolysis systems per month, per hour the fume amount of Chu Liing is 30m
3, dust concentration is 11g/m
3, adopt wet scrubbing mode separating treatment flue dust, the operation of selecting civilian formula washer to carry out one month gets residue and oven dry through filter liquide, obtains the 269kg mixed powder, and the rate of recovery is 98%.
3, be that example is carried out flue dust recovery design to produce 30 tons of praseodymium neodymium alloy electrolysis systems per month, adopt the electrostatic precipitation mode to reclaim the improvement flue dust.The designing treatment fume amount is 80m
3/ hour, dust concentration is 10.49g/m
3Through one month operation, reclaim powder 578kg altogether, the rate of recovery is 99%.
