The invention provides an anhydrous hydrogen fluoride production process; reaction raw materials fluorite powder and sulfate are mixed by an external mixer and enter into a converter with jacket; hot air with the temperature of 350 DEG C to 600 DEG C is fed in the jacket; the fluorite powder and the sulfate have chemical reaction and produce hydrogen fluoride; the produced hydrogen fluoride enters into a scrubber from a furnace header to be washed; the washed hydrogen fluoride enters into an intermediate tank from a condenser, and then receives distillation and degasification to prepare the finished product anhydrous hydrogen fluoride; solid residue is emitted from a furnace tail.

本发明提供一种无水氟化氢生产工艺，反应原料萤石粉及硫酸经外混器混合后进入带有夹套的转炉，向夹套内通入350～600℃的热风，萤石粉和硫酸在发生化学反应生成氟化氢，生成的氟化氢气体由炉头进入洗涤塔进行洗涤，洗涤后的氟化氢由冷凝器进入中间槽，然后经过精馏、脱气制得成品无水氟化氢；固体残渣由炉尾排出。
