The smoke absorption cover of vacuum fan is arranged near rare earth electrolysis cell working face, directly can take the harmful smoke that rare earth electrolysis cell produces away, Rare Earth Electrolysis flue gas enters into heat-exchanger rig, tornado dust collector, absorption column of gas by vacuum fan successively, finally outwardly discharges.
High-temperature electrolysis flue gas corrosion strengthens, and be unfavorable for the work-ing life of flue gas purifying equipment, flue gas carries out heat exchange in heat-exchanger rig, and after heat exchange, flue-gas temperature reduces.Flue gas is dedusting in tornado dust collector, and gained dust Rare-Earth Content, up to more than 70%, has great recovery value.Flue gas after dedusting introduces absorption tower, except clean emission to external world after fluorine and further dedusting in absorption tower.
Compared with prior art, the Rare Earth Electrolysis flue gas processing device that the utility model adopts heat transfer tube, tornado dust collector, absorption column of gas to connect successively, reaches following effect:
1. reclaim electrolysis flue gas waste heat, reduce flue-gas temperature, improve heat energy service efficiency, reduce flue gas corrosion, extension device work-ing life;
2. equipment is simple, and efficiency of dust collection is high, can improve the rate of recovery of rare earth dust;
3. defluorination effect is good, has desirable decontamination effect improving;
4. the clean emission of wastewater zero discharge and flue gas is realized, energy-saving protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the utility model proposes for rare earth molten-salt electrolysis stove harmful smoke treatment facility, comprise heat transfer tube 1, tornado dust collector 2 and absorption column of gas 3.
The inwall of heat transfer tube 1 is provided with spiral heat exchange tube 4 along its length, the two ends up and down of spiral heat exchange tube 4 are respectively equipped with heat transferring medium import 5 and heat transferring medium outlet 6, the lower end of heat transfer tube 1 is connected with vacuum fan 7, the blast inlet of vacuum fan 7 is provided with smoke absorption cover 8, and the upper end of described heat transfer tube 1 connects the intake interface of described tornado dust collector 2 by tracheae.The harmful smoke be drawn into of vacuum fan upwards flows from the below of heat transfer tube, contrary with the flow direction of the heat transferring medium of spiral heat exchange tube 4, this makes it possible to ensure good heat exchange efficiency.
Tornado dust collector 2 give vent to anger interface connect flue 9, flue 9 extend into the bottom of absorption column of gas 3, and the bottom of tornado dust collector 2 is provided with the ash bucket 10 for collecting flue dust.Absorption column of gas 3 interior lower end is provided with circulation storage area 31, the top of storage area 31 is fixed wtih a loose tobacco pipe 11, loose tobacco pipe 11 smoke outlet upward and lower end is arranged on the smoke place end of flue 9, storage area 31 is connected with water spray circulation tube 12, water spray circulation tube 12 is provided with recycle pump 13, and the upper end of water spray circulation tube 12 is provided with a draining fog spray head 14 of the inner upper end being arranged on absorption column of gas 3.The flue gas that rare earth electrolysis cell produces by vacuum fan of the present utility model is introduced in heat transfer tube and is carried out heat exchange, after flue gas heat exchange, temperature reduces, then flue gas is introduced tornado dust collector, tornado dust collector can remove dedusting larger for particle in flue gas rapidly, efficiency of dust collection can reach 95%, after dedusting, flue gas introduces absorption column of gas through flue again, waterfog head is had in absorption column of gas, waterfog head 11 sprays water smoke and absorbs the fluorine in flue gas and remain dust, and further cooling gas, purify flue gas completely and discharged by the exhanst gas outlet of absorption column of gas.
