Sawdust passes through charcoal discharge gate in time and is discharged.
Further, the sawdust for being adsorbed with phosphoric acid drop is sent into phosphoric acid method life by transporter by the charcoal discharge gate
It produces in activated-carbon device, the sawdust for having adsorbed phosphoric acid can be used as the raw materials for production of active carbon, realize recycling for phosphoric acid；Its
In, producing active carbon by phosphoric acid method device is this field Typical reactive charcoal process units, not as the difference of technical scheme
Technical characteristic.
Preferably, using alkaline water spray in the spray column.
Further, it is additionally provided with circulation line in the spray column, sprays the alkaline water to get off and returns spray through circulation line
Head is recycled.
The cyclone separator bottom, which is equipped at the top of discharge outlet, is equipped with gas discharge outlet, is removed in tail gas by cyclonic separation
Moisture, and be up to cleaning emission request gas discharged.
The utility model has the advantages that
1, the utility model exhaust gas cleaner absorbs phosphoric acid, alkali spray, whirlwind water removal three-level unit using sawdust, containing height
The flue gas of concentrated phosphoric acid first passes through the absorption tower of filling sawdust, and 99% phosphoric acid is absorbed by sawdust, and remaining phosphoric acid is sprayed by alkalinity
Liquid is collected, and flue gas removes steam through cyclonic separation again, and last clean gas cleans discharge；
2, the utility model exhaust gas cleaner sawdust after absorbing saturation phosphoric acid, is passed through by entering at the top of absorption tower by bottom
Auger discharging, the sawdust for having adsorbed phosphoric acid can be used as activation raw material, and activation furnace activation production active carbon is sent into after with phosphoric acid, real
Phosphoric acid purification is showed and has recycled；
3, the utility model exhaust gas cleaner spray column can be realized the circulation of alkaline water using alkaline water spray is recycled
It utilizes, can reduce operating cost, green economy.
