Dry-wet combined system for inhibiting dust and sulfur dioxide in titanium concentrate drying flue gas

The utility model relates to a dry-wet combined system for inhibiting dust and sulfur dioxide in titanium concentrate drying flue gas. The dry-wet combined system comprises a flue gas washing system and a boiler gas washing system, wherein the flue gas washing system comprises a cyclone dust collector (2), a flue gas washer (3) and a flue gas multi-blocking demister (4), and an inlet of the cyclone dust collector (2) is communicated with a flue gas pipeline; the pot gas washing system comprises a pot gas washer (7), a pot gas multi-gear demister (8) and a pot gas fan (9); an inlet of the pot gas washer (7) is communicated with the interior of the drying machine (1); the flue gas scrubber (3) and the pot gas scrubber (7) are obliquely arranged, and the spraying opening is opposite to the inlet. Flue gas is subjected to pre-dedusting through the cyclone dust collector (2) and then washed through the flue gas washer (3), pot gas is directly washed through the pot gas washer (7), water mist makes reverse contact
