Form balance.
Originally show invention when in use, first pour into iron powder in reaction tank, be then turned on
Spent acid is delivered in reaction tank by feed inlet, and open the circulation pump conveys spent acid by reflux line to mixing bottom of the tube
Liquid circulation flowing is formed to drive iron powder to rise, while driving spent acid to seethe so that reduction reaction, reaction fully to occur with iron powder
The spent acid finished reaches mixing nozzle upper end under circulating pump drive and enters baffle, and iron powder freely sinks under the blocking of baffle
It forms sediment, the spent acid after reduction reaction is then in reaction tank top, and the iron powder of precipitation is collected to mixing bottom of the tube through inclined plate again, also
Spent acid after original reaction is discharged through outlet valve 8, other spent acid continue to drive iron powder upward along mixing tube under circulating pump drive
It flows and continues reduction reaction.
Compared with prior art, the present invention what is obtained has the beneficial effect that：It can make to own by the inclined plate being obliquely installed
Iron powder concentrates on the bottom middle of reaction tank, and fully blows afloat all iron powders by the cooperation of reflux line and circulating pump,
So that iron powder is fully risen floating in reaction tank, improves time of contact and the contact area of iron powder and spent acid, greatly improve
The reduction efficiency of spent acid saves reduction cost；Iron powder after simultaneous reactions can be automatic by the guiding of inclined plate after falling
It is gathered in reaction tank bottom middle, cycle is then proceeded to and floats and carry out reduction reaction, improve reaction efficiency, ensure that oxygen
Change the abundant progress of reduction reaction；Baffle can effectively change the flow direction of the iron powder and spent acid that are discharged by mixing tube, make iron powder
Deposition downwards, to prevent it from being taken out of from outlet valve by spent acid, agent structure is simple, and design concept is ingenious, side safe to use
Just, application environment is friendly, wide market.
