Valve 6 and temperature regulating device 7 processed flow into reservoir 8, and the solution in reservoir 8 can carry out certain precipitation, be slightly soluble in the sulfurous of water
Sour magnesium can be deposited to the bottom of reservoir 8 with the solid impurity come is flowed through, and the second control valve 14 is opened after precipitating the regular hour,
The magnesium sulfite solution of 8 bottom of reservoir flows through the second control valve 14 under the action of drawing liquid pump 9 and flows back to bubble type reaction again
In device 13, above-mentioned steps are recycled, until after being magnesium sulfate by magnesium sulfite catalysis completely, the clear liquid containing magnesium sulfate is from second
Liquid outlet 10 is discharged, and carries out recycling.In the present invention, because catalyst belongs to the process recycled, in reservoir 8
In precipitated only supernatant liquor can be discharged and the inside and do not include magnesium sulfite, the final magnesium sulfite after each cycle
Can be fully oxidized to magnesium sulfate will not precipitate in reservoir at this time.
Inlet 2 can be always maintained at open state in entire cyclic process, ensure that slurries constantly flow into.Meanwhile root
According to needs, control valve can be set on the pipeline being connect with inlet 2, the flow of slurries can be controlled at any time.
Embodiment described above is only that the preferred embodiment of the present invention is described, and is not carried out to the scope of the present invention
It limits, under the premise of not departing from design spirit of the present invention, those of ordinary skill in the art make technical scheme of the present invention
Various modifications and improvement, should all fall into claims of the present invention determination protection domain in.
