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。

This design is to dials forks the components the processing craft and the jig design, its components are the forging, has the volume to be small, components complex characteristic,Because the surface is easier than the hole to process, when formulation technological process, first the machined surface, then processes other take the surface as the datum,In which various working procedures jig all uses the unit clamp, special regarding processes the big end of hole, the trough and drills the capitellum hole incline eyelet in the working procedure, Chooses locate mode which two sells at the same time, and operates the simple manual clamp way clamp, its organization design is simple, the convenience also can satisfy the request.
