Abstract
The present invention provides a zero pollution recovery system for safely producing anhydrous fluorine hydride, comprising: a compartment, a reactor for producing fluorine hydride, and a water pool; the reactor is disposed in the compartment; the water pool is disposed at the bottom of the compartment; absorption hoods are respectively disposed above both ends of the reactor for absorbing fluorine hydride gas; at least two absorption towers mutually connected in series via pipes are disposed above the compartment; water pipes connected with the water pool are respectively disposed at the top and bottom of the absorption tower; and a cooler and a receiver connected with the water pool is disposed on the pipes. The present invention has the advantages of being able to control the range over which fluorine hydride can diffuse.
