It closes.
Further, air pipeline of the present invention extends to one end of mixing infratubal port and the lower port of mixing tube is held
It is flat, or higher than mixing within infratubal port 5cm, when ensuring that the air of air pipeline is all blown into mixing tube, can be formed
Enough jet streams make iron powder, abrasive grit fully suck mixing tube, while upward because of air pipeline nozzle, can also prevent equipment from stopping
When only running, the iron powder on inclined plate piles up air pipeline nozzle, causes to block.
In the use of the present invention, first pouring into iron powder in reaction tank, it is then turned on feed inlet and spent acid is delivered to reaction tank
It is interior, it opens air compressor and air is conveyed to mixing bottom of the tube by air pipeline, to drive iron powder to rise, while driving spent acid
It seethes so that reduction reaction fully occurs with iron powder, reacts the spent acid finished and is reached under the drive of air and mix nozzle upper end and go forward side by side
Enter baffle, air escapes liquid level, and spent acid is folded to downlink, and the iron powder of iron powder free sedimentation, precipitation is collected to mixing tube again through inclined plate
Bottom, iron powder and spent acid are formed inside and outside mixing tube and are circulated, and purified spent acid is discharged through outlet valve.
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 can be filled by coordinating with the air pipeline being arranged right over reaction tank
Point all iron powders are blown afloat, iron powder is made fully to rise floating in reaction tank, improved iron powder and the time of contact of spent acid and contact
Area greatly improves the reduction efficiency of spent acid, saves reduction cost;Iron powder after simultaneous reactions can pass through after falling
The guiding of inclined plate is gathered in reaction tank bottom middle automatically, then proceedes to cycle and floats and carry out reduction reaction, improves anti-
Efficiency is answered, ensure that the abundant progress of redox reaction;Baffle can effectively change the iron powder being discharged by mixing tube and give up
The flow direction of acid, makes iron powder deposit downwards, to prevent it from being taken out of from outlet valve by spent acid, agent structure is simple, design concept
Ingenious, safe and convenient to use, application environment is friendly, wide market.
